Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a flowchart illustrating an embodiment of a communication method of an electrical home appliance according to the present application. Specifically, embodiments of the present disclosure may include the steps of:
Step S11: the current home appliance utilizes a first transport layer protocol to dynamically networking with other home appliances.
In the embodiment of the disclosure, the household electrical appliance comprises any electrical appliance used daily by a family. For example, the home devices may specifically include, but are not limited to: kitchen appliances such as an electric cooker, an electric stewpot, a dish washer, a refrigerator and the like, refrigerating/heating equipment such as an electric fan, an air conditioner and the like, cleaning/washing appliances such as a washing machine, a clothes drying machine, a sweeping robot and the like, intelligent appliances such as an electronic lock, an intelligent socket, an intelligent lamp, a smoke/water immersion alarm and the like, and intelligent household equipment such as a home service robot and the like are not limited herein.
In one implementation scenario, the current home device may refer to any home device in the home communication system. It should be noted that, the home communication system includes a plurality of home devices in the same network, for example, the home communication system may specifically include an electric cooker, an air conditioner, a sweeping robot and an electronic lock in the same network, and any one of the electric cooker, the air conditioner, the sweeping robot and the electronic lock may be regarded as a current home device, for example, in a case that the electric cooker is regarded as a current home device, the air conditioner, the sweeping robot and the electronic lock may be regarded as other home devices, in a case that the air conditioner is regarded as a current home device, the electric cooker, the sweeping robot and the electronic lock may be regarded as other home devices, and in a case that the sweeping robot and the electronic lock are respectively regarded as current home devices, and the like, which is not repeated herein. In other cases, the home communication system includes home devices, and so on, which are not further examples herein.
In the embodiment of the disclosure, the home appliance can be dynamically networked in a WiFi (Wireless Fidelity ) environment, and compared with a general network environment, in the home environment, the specificity of frequent plugging of the home appliance exists, for example, the electric rice cooker is powered on when cooking, and is powered off when cooking is completed; or the television is powered on during watching and powered off during rest, so various are not taken as examples, so in order to adapt to the special feature, it is necessary to improve the flexibility of dynamic networking, and in view of this, the first transport layer protocol may be UDP (User Datagram Protocol, user data packet protocol). UDP provides a method for transmitting encapsulated packets without establishing a connection, the UDP packets being composed of a header and a payload, wherein the header specifies the source port and the destination port and the payload contains information to be communicated by the UDP packets, such as may include, but is not limited to: the type of equipment (e.g., washing machine, air conditioner, electronic lock, rice cooker, sweeping robot, etc.) of the home appliance, etc., is not limited herein.
In one implementation scenario, device discovery may be performed using a first transport layer protocol to network with other home devices. According to the mode, through device discovery, each household appliance can know the existence of other household appliances, so that basic conditions can be provided for dynamic networking, and the success rate of dynamic networking is improved.
In a specific implementation scenario, the first transport layer protocol may be used to monitor the identification information of other home devices, and the first transport layer protocol may be used to broadcast the identification information of the current home device, so that each home device may know the existence of other home devices by broadcasting the identification information of its own device and monitoring the identification information of other devices. Taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, the electric cooker can monitor the identification information of other household appliances such as the air conditioner, the sweeping robot and the electronic lock through a first transmission layer protocol, broadcast the identification information of the electric cooker, the sweeping robot and the electronic lock through the first transmission layer protocol, and similarly, the air conditioner can monitor the identification information of other household appliances such as the electric cooker, the sweeping robot and the electronic lock through the first transmission layer protocol, broadcast the identification information of the electric cooker, the sweeping robot and the electronic lock through the first transmission layer protocol, and the like, and the details are omitted.
Specifically, after the home appliance is powered on, the identification information of the home appliance can be broadcast through a first transmission layer protocol, and the identification information of other home appliances can be intercepted through the first transmission layer protocol, so that dynamic networking is performed; after the home appliance is powered down, the hardware circuit of the home appliance for network communication stops working, so that the home appliance can not broadcast or listen any more, i.e. the home appliance can be regarded as being in a offline state. For convenience of description, taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, at a moment after the air conditioner, the sweeping robot and the electronic lock finish dynamic networking, responding to a cooking requirement of a user, the electric cooker is switched to an upper power state, in this case, the electric cooker can broadcast identification information of own equipment and monitor the identification information of the air conditioner, the sweeping robot and the electronic lock, and in this process, the air conditioner, the sweeping robot and the electronic lock can also broadcast the identification information of the own equipment and monitor the identification information of other household appliances, so that the electric cooker, the air conditioner, the sweeping robot and the electronic lock finish networking. Further, at a certain moment after the electric rice cooker and the air conditioner, the sweeping robot and the electronic lock complete networking, in response to the completion of cooking by a user, the electric rice cooker can be switched to a power-down state, in this case, the electric rice cooker cannot be broadcasted or intercepted any more, namely, the electric rice cooker is in a power-down state at this moment, in the process, the air conditioner, the sweeping robot and the electronic lock can respectively broadcast the identification information of the self equipment and intercept the identification information of other household appliances, so that the air conditioner, the sweeping robot and the electronic lock complete dynamic networking. Therefore, the dynamic networking is performed through the first transmission layer protocol, and even if the household electrical appliance is powered on/off frequently, the networking can be performed adaptively, so that the networking reliability is further improved.
It should be noted that the identification information may include, but is not limited to, a device type of the home appliance, such as a washing machine, an air conditioner, an electronic lock, an electric cooker, a sweeping robot, and the like. As previously mentioned, the first transport layer protocol may be UDP, in which case the identification information may be located in the payload of the UDP packet.
In another specific implementation scenario, as mentioned above, unlike a general network environment, in a home environment, a home device usually has a frequent plug, so it is necessary to perform a communication process through the second transport layer protocol later, and meanwhile, consider improving flexibility and reliability of the communication, so that the home device may use a C/S mode (i.e. Client/Server) for communication. In this case, the master device and the slave device may be selected from the current home device and the other home devices based on the identification information of the other home devices obtained by interception. It should be noted that, the master device is a Server (i.e., a Server), and the slave device is a Client (i.e., a Client). To accommodate the above-mentioned specificity of the home environment, the second transport layer protocol may specifically be a TCP protocol (i.e. Transmission Control Protocol, transmission control protocol).
Specifically, in order to ensure the consistency of the master devices respectively determined by different home devices in the same network, a master device selection policy may be preset, and different home devices in the same network may select a master device and a slave device from the current home devices and other home devices according to the master device selection policy. For example, when the identification information includes device types, the home devices corresponding to the device types with the highest priority may be selected as the master device according to priorities of different device types, and other home devices except the home devices may be selected as the slave devices. The priority of the home devices may be preset, for example, from high to low may be set as follows: air conditioner, robot, rice cooker, electronic lock sweep floor, do not limit here.
It should be noted that, the priority of the home appliance may also be set according to the interaction frequency between the home appliance and the user, and the interaction frequency between the home appliance and the user and the priority are in a positive correlation relationship, that is, the priority of the home appliance frequently interacted with the user is also higher. Taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, a user interacts with the air conditioner frequently in high-temperature time periods such as summer or low-temperature time periods such as winter, so that the priority of the air conditioner can be higher than that of the electric cooker, the sweeping robot and the electronic lock in the time periods, and the user does not interact with the air conditioner almost in normal-temperature time periods such as spring or autumn, so that the priority of the air conditioner can be lower than that of the electric cooker, the sweeping robot and the electronic lock in the time periods. I.e. the priorities of the various device types may be varied according to the frequency of interaction of the home device with the user at different time periods.
As previously described, during use, the home devices may be powered up/down frequently. If the electric cooker is powered on during cooking, the electric cooker is powered off after cooking; or the sweeping robot is electrified when sweeping, and is electrified after sweeping; or, the air conditioner is powered on during heating/cooling, and powered off after the heating/cooling is finished, so that other household appliances can be pushed in the same way, and the heating/cooling is not exemplified here. Therefore, in order to improve the stability of networking and subsequent communication, the steps of selecting the master device and the slave device from the current home device and the other home devices based on the identification information of the other home devices obtained by interception may be periodically performed.
For convenience of description, still taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, at a certain moment after the air conditioner, the sweeping robot and the electronic lock finish dynamic networking, the electric cooker can be switched to an upper electric state in response to a cooking requirement of a user, in this case, the electric cooker can broadcast and listen to the electric cooker, so that the electric cooker can finish dynamic networking with the air conditioner, the sweeping robot and the electronic lock, in this case, the air conditioner can be used as a main device based on identification information of various different household appliances, and the electric cooker, the sweeping robot and the electronic lock can be used as slave devices. Since then, the above-described steps of selecting a master device and a slave device may be performed once every fixed period (e.g., 10 seconds, 20 seconds, etc.). Further, at a certain moment after the electric cooker, the air conditioner, the sweeping robot and the electronic lock complete networking, the electric cooker can be powered down in response to the completion of cooking by a user, in this case, the electric cooker cannot broadcast or listen through the first transmission layer protocol any more, that is, when the electric cooker is in a down state and reaches an integer multiple (for example, 1 time, 2 times, 3 times, etc.) of the fixed period again at the current moment, the step of selecting the master device and the slave device is performed, so that the air conditioner can be used as the master device, and the sweeping robot and the electronic lock can be used as the slave device. Other situations can be similar and are not exemplified here.
In still another specific implementation scenario, in order to improve reliability of subsequent communication using the second transport layer protocol on the premise of improving networking flexibility, the current home appliance may use the first transport layer protocol to monitor identification information of other home appliances and use the first transport layer protocol to broadcast identification information of its own appliance, and on this basis, the master device and the slave device may be selected from the current home appliance and other home appliances based on the monitored identification information of the other home appliances. The specific process can be referred to the above related description, and will not be repeated here.
Specifically, referring to fig. 2 in combination, fig. 2 is a process schematic of an embodiment of dynamic networking. As shown in fig. 2, in the dynamic networking process, the home device a may monitor the identification information B of the home device B and broadcast the identification information a of the home device a, and at the same time, the home device B may monitor the identification information a of the home device a and broadcast the identification information B of the home device B, so that, whether the home device a or the home device B, after broadcasting and monitoring, the home device a and the identification information B may be learned, so that based on the identification information a and the identification information B, the home device a and the home device B may make master-slave decisions, that is, both may select a master device and a slave device from the home device a and the home device B. As described above, since different home devices in the same network perform master-slave decision according to the same master device selection policy, it is possible to ensure that the master devices selected by home device a and home device B are consistent. Other situations can be similar and are not exemplified here.
In the dynamic networking process, the identification information of other household appliances can be firstly monitored, and then the identification information of the current household appliances is broadcasted; the identification information of the current home appliance may be broadcast first, and then the identification information of other home appliances may be monitored, which is not limited herein.
Step S12: after networking with other home devices, the second transport layer protocol is utilized to communicate with the other home devices.
As described above, in the whole dynamic networking process, the current home device may select the master device and the slave device from the current home device and other home devices, and when the current home device is the master device or the slave device, different communication steps may be adopted to interactively communicate with the other home devices. As previously mentioned, the second transport layer protocol is specifically the TCP protocol. So as to adapt to the special situation of frequent plugging of household appliances in the household environment. In the process of interactive communication through the TCP protocol, the master device and the slave device establish connection through the three-way handshake protocol, namely, after one of the master device and the slave device firstly sends out a SYN connection request, the other party waits for answering SYN+ACK, finally carries out ACK confirmation on the SYN of the other party, and after the three-way handshake is completed, the two parties can be regarded as successful connection establishment and start to transmit data packets. After the data packet transmission is completed, since the TCP connection is full duplex, each direction must be closed separately, so both parties can terminate the connection by waving their hands four times, i.e. one party sends a FIN first for closing the data transmission from the party to the other party, the other party returns an ACK to confirm the closing after receiving the FIN, and then continues to send a FIN to the other party for closing the data transmission to the other party, and the other party returns an ACK to confirm the closing after receiving the FIN. That is, in the embodiment of the present disclosure, since the home environment is different from the general network environment, special situations such as frequent plugging and unplugging of the home devices exist, and in order to adapt to the special situations, in the dynamic networking process, the embodiment of the present disclosure adopts the UDP protocol to improve flexibility of dynamic networking, and after networking is completed, the embodiment of the present disclosure adopts the TCP protocol to implement communication between the home devices to improve reliability of communication, so that by combining both the UDP protocol and the TCP, the embodiment adapts to special situations that the home environment is different from the general network environment, so as to improve reliability of communication while improving flexibility of networking.
In one implementation scenario, when the current home appliance is a slave device, in the case of detecting the instruction to be executed, the second transport layer protocol may be utilized to send an execution inquiry message to the master device, and in the case of receiving the execution instruction sent by the master device, the second transport layer protocol is utilized to execute the instruction to be executed. It should be noted that the instructions to be executed may include, but are not limited to, voice instructions. For example, in the case where the home appliance includes the electric rice cooker, the instruction to be executed may include "start cooking", in the case where the home appliance includes the sweeping robot, the instruction to be executed may include "start sweeping", in the case where the home appliance includes the air conditioner, the instruction to be executed may include "turn down the temperature", in the case where the home appliance includes the electronic lock, the instruction to be executed may include "unlock lock alarm", and the like, which are not limited herein.
In a specific implementation scenario, the current home appliance may analyze the instruction to be executed to obtain correlations between the instruction to be executed and each home appliance located in the same network as the current home appliance, and the execution inquiry message may include the correlations between the instruction to be executed, so that the master device determines the home appliance executing the instruction to be executed according to the correlations between the instruction to be executed and the current home appliance; or, the current home appliance may package the detected instruction to be executed into the execution query message, so that the master device analyzes the instruction to be executed to obtain the correlation between the instruction to be executed and each home appliance located in the same network with the current home appliance, and determines, according to the correlation between the instruction to be executed, the home appliance executing the instruction to be executed, which is not limited herein.
In another specific implementation scenario, as mentioned above, the to-be-executed instruction may be a voice instruction, and the current home appliance may further detect an audio intensity of the to-be-executed instruction, and package the detected audio intensity and the to-be-executed instruction together into an execution query message, so that the master device analyzes the to-be-executed instruction, obtains correlations between the to-be-executed instruction and each home appliance located in the same network with the current home appliance, and determines the home appliance executing the to-be-executed instruction according to the correlations between the to-be-executed instruction and the audio intensity.
It should be noted that, the specific process of determining the home device to execute the instruction may refer to the following related description, which is not repeated herein.
In another implementation scenario, when the current home device is the master device, the current home device may receive an execution inquiry message from a slave device, select an execution device from at least the slave devices that send the execution inquiry message, and send an execution instruction to the execution device using the second transport layer protocol, where the execution instruction is used to instruct the execution device to execute the instruction to be executed. If the slave device does not detect the instruction to be executed, the slave device may be regarded as an execution device that the slave device does not desire to execute the instruction to be executed, and thus, when the execution device is selected, the slave device that does not transmit the execution inquiry message may be excluded. Taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, as mentioned above, the air conditioner can be used as a master device, and the electric cooker, the sweeping robot and the electronic lock can be used as slave devices, when a user uses the air conditioner in a bedroom, if there is a temperature adjustment requirement, the user generally interacts with the air conditioner at a position close to the air conditioner, such as sending a voice command, the user does not generally send a voice command in a kitchen or a toilet, in this case, the sweeping robot in a living room, the electronic lock in a door and the air conditioner in the bedroom can detect the voice command, but the electric cooker in the kitchen may not detect the voice command, so that the electric cooker does not send an execution inquiry message to the air conditioner, and when the execution device is selected, the electric cooker can be excluded. Other situations can be similar and are not exemplified here.
In a specific implementation scenario, when the current home appliance is the master device, if the current home appliance detects that the instruction to be executed is obtained, the executing device may be selected from the current home appliance and the slave device that sends the execution inquiry message. As described above, the to-be-executed instruction may be packaged into the execution query message, and on this basis, the master device may analyze the to-be-executed instruction to obtain the correlation between the to-be-executed instruction and the current home appliance and the slave device that sends the execution query message, respectively, so that the home appliance with the highest correlation may be used as the execution device.
For convenience of description, taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, under the condition that an instruction to be executed is "start sweeping", the correlation degree between the instruction to be executed "start sweeping" and each household appliance device can be analyzed and obtained as follows: the sweeping robot (97%), the electric cooker (1%), the air conditioner (1%), and the electronic lock (1%), so the sweeping robot can be used as an execution device, and other cases can be similar, and the sweeping robot is not exemplified one by one.
In another specific implementation scenario, as described above, the to-be-executed instruction and the audio intensity of the to-be-executed instruction detected by the slave device may be packaged together into the execution query message, and on this basis, the master device may analyze the to-be-executed instruction to obtain correlations between the to-be-executed instruction and the current home appliance and the slave device that sends the execution query message, respectively, so that the execution device may be selected from the current home appliance and the slave device that sends the execution query message based on the correlations and the audio intensity. Specifically, the correlation and the audio intensity may be weighted to obtain a score value of each home appliance, and the home appliance with the highest score value may be used as the executing device.
For convenience of description, taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, under the condition that the instruction to be executed is "temperature-adjusting", the correlation degree between the instruction to be executed "temperature-adjusting" and each household appliance is respectively: sweeping robot (1%), rice cooker (20%), air conditioner (78%), electronic lock (1%), and audio intensity of the instruction to be executed that each tame electric installation detected respectively is: sweeping robot (5 dB), rice cooker (3 dB), air conditioner (30 dB), electronic lock (5 dB), under the condition that the weighting factors of relativity and audio frequency intensity are preset to 0.5 and 0.5 respectively, the score value of each household appliance is respectively: 3. 11.5, 54, 3, in which case the air conditioner with the highest score value may be used as the executing device, and the other cases may be similar, and are not exemplified here.
In yet another specific implementation scenario, when the current home appliance is the master device, if the master device does not detect the instruction to be executed, the executing device may be selected from the slave devices that send the execute query message. As described above, the to-be-executed instruction may be packaged into the execution query message, and on this basis, the master device may analyze the to-be-executed instruction to obtain the correlation between the to-be-executed instruction and the slave device that sends the execution query message, respectively, so that the home appliance device with the highest correlation may be used as the execution device.
For convenience of description, taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, when an instruction to be executed is "start sweeping", and the main equipment air conditioner does not detect the instruction to be executed, the correlation degree between the instruction to be executed "start sweeping" and the slave equipment sending the execution inquiry message is: the sweeping robot (98%), the electric cooker (1%), and the electronic lock (1%), so the sweeping robot can be used as an execution device, and the like, and the sweeping robot is not exemplified here.
In still another specific implementation scenario, as described above, the to-be-executed instruction and the audio intensity of the to-be-executed instruction detected by the slave device may be packaged together into the execution query message, and on this basis, the master device may analyze the to-be-executed instruction to obtain correlations between the to-be-executed instruction and the slave device that sends the execution query message, so that the execution device may be selected from the slave devices that send the query message based on the correlations and the audio intensity. Specifically, the correlation and the audio intensity may be weighted to obtain a score value of each home appliance, and the home appliance with the highest score value may be used as the executing device.
For convenience of description, taking an electric cooker, an air conditioner, a sweeping robot and an electronic lock as examples, when an instruction to be executed is "start cooking", and the main equipment air conditioner does not detect the instruction to be executed, the correlation degree between the instruction to be executed "start cooking" and the slave equipment sending the execution inquiry message may be respectively: the floor sweeping robot (1%), the electric cooker (98%), the electronic lock (1%), and the slave devices which send the execution inquiry messages respectively detect that the audio intensity of the instruction to be executed is: sweeping robot (5 dB), rice cooker (30 dB), electronic lock (5 dB), under the condition that the weighting factors of the correlation degree and audio intensity are preset to be 0.5 and 0.5 respectively, the score values of the slave devices for sending and executing the inquiry messages are respectively: 3. 64, 3, in which case the rice cooker with the highest score value may be used as the executing device, and the other cases may be similar, and are not exemplified here.
In yet another implementation scenario, referring to fig. 3 in combination, fig. 3 is a process diagram of one embodiment of a master device and a slave device communicating. As shown in fig. 3, the upper half part is a main device executing process, the lower half part is a slave device executing process, in the main device executing process and the slave device executing process, the same is that the main device executing process and the slave device executing process both detect an instruction to be executed, if a user sends the instruction to be executed, the slave device can interactively communicate with the main device through a second transport layer protocol under the condition of detecting the instruction to be executed, and in the communication process, an execution inquiry message is sent to the main device, if the main device also detects the instruction to be executed, the main device can select an executing device from the main device itself and the slave device sending the execution inquiry message, if the selected executing device is the main device itself, the instruction to be executed can be directly executed, and if the selected executing device is the slave device, an execution instruction can be sent to the slave device through the second transport layer protocol, so that the slave device executes the instruction to be executed under the condition of receiving the execution instruction; similarly, if the master device does not detect the instruction to be executed, the master device may select an execution device from the slave devices that send the execution inquiry message, and on this basis, may send an execution instruction to the slave devices through the second transport layer protocol, so that the slave devices execute the instruction to be executed when receiving the execution instruction. It should be noted that, for convenience of explanation, fig. 3 only schematically shows a communication flow in the case of only one slave device, and the like in the case of a plurality of slave devices, and is not exemplified here.
It should be noted that, as described above, in the communication process, the master device needs to take on the task of deciding the executing device of the instruction to be executed, so in the dynamic networking process, the interception/broadcasting identification information may include the computing power resource information, so in the master-slave decision process, the master device and the slave device may be selected from the current home devices and other home devices based on the computing power resource information.
In one implementation scenario, the computing power resource information may specifically include, but is not limited to: CPU (Central Processing Unit ), GPU (Graphic Processing Unit, graphics processor), memory, etc., without limitation.
In another implementation scenario, the home devices with the most abundant computing power resources can be selected as the master device according to the computing power resource information, and other home devices except the master device are regarded as the slave devices.
According to the scheme, the current household electrical appliance utilizes the first transmission layer protocol to carry out dynamic networking with other household electrical appliances, the first transmission layer protocol is the UDP protocol, and because the UDP protocol is a connectionless protocol, compared with a connection-oriented protocol, the networking can be carried out without holding hands for many times, so that the flexibility can be improved, and after the networking of the other household electrical appliances, the second transmission layer protocol is continuously utilized to carry out communication with the other household electrical appliances, and the second transmission layer protocol is the TCP protocol, the reliability in the communication process of the household electrical appliance can be ensured.

The processor, which may also be referred to as a CPU (Central Processing Unit ), may be an integrated circuit chip with signal processing capabilities. The processor may also be a general purpose processor, a digital signal processor (Digital Signal Processor, DSP), an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a Field programmable gate array (Field-Programmable Gate Array, FPGA) or other programmable logic device, discrete gate or transistor logic device, discrete hardware components.

Different from the foregoing embodiment, the first transport layer protocol is used to monitor the identification information of other home appliances, and the first transport layer protocol is used to broadcast the identification information of the current home appliances, so that the master device and the slave device are selected based on the identification information of the other home appliances obtained by monitoring, which is beneficial to improving the flexibility of home appliance networking and the reliability of home appliance communication.
In some disclosed embodiments, the step of selecting the master device and the slave device from the current home device and the other home devices is performed periodically based on the identification information of the other home devices obtained by interception.
Unlike the foregoing embodiments, by periodically performing the steps of selecting the master device and the slave device, it is possible to facilitate improvement in stability of networking and subsequent communication in the case where the home appliance is frequently powered on/off.

In contrast to the foregoing embodiment, if the home appliance is a slave device, in the case where the to-be-executed instruction is detected, the execution query message is sent through the second transport layer protocol, and in the case where the execution instruction sent by the master device is obtained through the second transport layer protocol, the to-be-executed instruction is executed, so that the master device can uniformly process the execution query message, and communicate with the second transport layer protocol in the whole process, which can be beneficial to improving the reliability of the device for determining the to-be-executed instruction to be subsequently executed.
