The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present invention will be described below with reference to the accompanying drawings.
For a clear understanding of the technical solutions of the present application, the prior art solutions will be described in detail first. Currently, a control unit and a slave unit are integrated on a board card of a communication device. The control unit is connected with different slave units through different buses, different buses use different protocols, and the buses have different clocks and redundant signals. Thus, when the control unit communicates with a plurality of slave units in real time, a complex protocol needs to be processed, and communication can be performed only through different buses, respectively, resulting in a low signal transmission rate between the control unit and the slave units.
Therefore, in order to solve the problem of low signal transmission rate between the control unit and the slave units in the prior art, the inventor finds that, in order to solve the problem, multiple buses can be integrated, so that the control unit and each slave unit are connected and communicated through the same bus, and the signal transmission rate between the control unit and the slave unit is improved. The method comprises the following steps: when a control instruction is issued, the control unit acquires a first control instruction to be sent to at least one slave unit. The first control instruction includes a slave unit identification. And generating a corresponding issuing serial frame according to the first control instruction. The outgoing serial frame is sent over the bus to the slave unit set. And when uploading the state signals, the slave unit sets acquire at least one uploading state signal to be uploaded to the control unit by the slave unit. The upload status signal comprises a slave unit identification. And generating a corresponding uploading serial frame according to the uploading state signal. And transmitting the uploading serial frame to the control unit through the bus so that the control unit determines an uploading state signal corresponding to the slave unit according to the slave unit identification.
According to the serial communication method, the control unit and the slave unit set are connected through the same bus, the same communication protocol is adopted, the control unit can communicate with each slave unit in real time through only one bus, and the signal transmission rate is improved.
The inventor puts forward the technical scheme of the application based on the creative discovery.
The application scenario of the serial communication method provided by the embodiment of the invention is described below. As shown in fig. 1, in this embodiment, in order to better describe an application scenario of the serial communication method, other devices in the scenario are also described at the same time. Wherein 10 is a board card, 11 is a control unit, 12 is a slave unit set, and 13 is a bus. The control unit 11, the slave unit set 12, and the bus 13 are provided on the board card 10. The slave unit set 12 includes a plurality of slave units, as shown in the drawing as slave unit a, slave unit b, slave unit c to slave unit n.
In the process of communication between the control unit and the slave unit set, if the control unit needs to issue data, for example, issues control instructions to the slave unit a, the slave unit b and the slave unit c, corresponding issuing serial frames are generated according to the control instructions to be sent to the slave unit a, the slave unit b and the slave unit c. The issued serial frame contains slave unit a, slave unit b, and slave unit identification of slave unit c. The outgoing serial frame is then sent over bus 13 to the slave unit set 12. The slave unit set 12 performs identification processing, such as decoding processing and protocol processing, based on the issued serial frame, and transmits corresponding data therein to the slave unit a, the slave unit b, and the slave unit c based on the slave unit identifications of the slave unit a, the slave unit b, and the slave unit c.

Fig. 2 is a flow chart of a serial communication method according to a first embodiment of the present invention, as shown in fig. 2, in this embodiment, a control unit is connected to a slave unit set through the same bus, and the slave unit set includes a plurality of slave units. The serial communication method is applied to the control unit. The serial communication method provided in this embodiment includes the following steps:
step S101, a first control instruction to be sent to at least one slave unit is acquired. The first control instruction includes a slave unit identification.
The existing control unit is connected with different slave units through different buses, the protocols adopted by each bus are different, and the clocks of each bus are different. This approach will occupy multiple pin resources of the control unit, while the clocks are not uniform and the protocol processing is complex. In this embodiment, the control unit is connected to the slave unit set through a bus, and a communication protocol is adopted to reduce the complexity of protocol processing. The bus may include a serial data line for synchronizing timing and a clock line for transmitting serial frames.
The slave unit set may include a plurality of slave units, each of which is preset with a corresponding slave unit identifier, and the slave unit identifier may be a slave unit number, a slave unit name, or the like.
Step S102, generating a corresponding issuing serial frame according to the first control instruction.
In this embodiment, the first control instructions corresponding to different slave units may be different, and when the issuing serial frame is generated according to the first control instructions, the protocol frame processing and the encoding processing may be performed according to a preset protocol, so as to generate the issuing serial frame. The method comprises the following steps:
and carrying out data encoding processing and protocol frame processing on the first control instruction to generate a corresponding issuing serial frame.
The control unit may be provided with a data encoding and decoding module for encoding the issued control instruction and decoding the received uploading serial frame. And a serial protocol frame processing module for processing protocol frames of a preset protocol can be also arranged.
Optionally, the slave unit set on the board card further includes: the high-speed signal unit is connected with the control unit, and has certain requirements on the communication speed, and the transmission priority is required to be set. Thus, the method of the present embodiment may further comprise the steps of:
and acquiring a second control instruction to be sent to the high-speed signal unit. The second control instruction includes a high speed signal unit identification.
After the second control instruction is acquired, determining a preset sending priority corresponding to the first control instruction and a preset sending priority corresponding to the second control instruction according to the slave unit identifier and the high-speed signal unit identifier. The slave unit identifier and the high-speed signal unit identifier have a mapping relation with a preset transmission priority.
And encoding the corresponding first control instruction and second control instruction according to a preset protocol and a preset encoding strategy to generate a corresponding issuing serial frame. The preset encoding strategy is to encode the corresponding first control instruction and second control instruction according to the sequence from the highest preset sending priority to the lowest preset sending priority.
In this embodiment, the preset transmission priority may be set according to the priority that the high-speed signal unit is greater than the slave unit, so as to preferentially transmit and process the second control instruction of the high-speed signal unit, and improve the communication rate of the high-speed signal unit. Meanwhile, the sending priority can be set for different slave units according to actual requirements, so that when the first control instruction and the second control instruction are coded according to a preset protocol and a preset coding strategy, the priority code with the highest sending priority is coded at the head of the serial frame.
As shown in fig. 3, CLK refers to clock lines, MS0-1 to MS0-6, SM0-1 to SM0-6, MS1-1 to MS1-6, SM1-1 to SM1-6, MSn-1 to MSn-6, SMn-1 to SMn-6 refer to signal identifications, a codec module and a serial protocol frame processing module are provided in the control unit, and a serial protocol frame processing module and a codec module are provided in the slave unit set. The control unit is connected with the slave unit set through a bus, and the bus comprises a clock line and a serial data line marked with a serial data frame in the figure. After decoding and frame processing via the slave unit set, the issuing serial frame can parse out specific control commands to be transmitted by means of different kinds of signals, such as MS0-1, SM 0-1.
Alternatively, in this embodiment, as shown in FIG. 4, P0-1 to P1-12, P1-1 to P1-12, P2-1 to P2-12 and Pn-1 to Pn-12 refer to byte identifiers, and MS0-1 to MS0-6 and SM0-1 to SM0-6 refer to signal identifiers. h1 and h2 refer to frame header, TR and RE index identifier, TR is the down flag, RE refers to the up flag. C refers to CRC8, a cyclic redundancy check code. As shown, issuing a serial frame includes:
a frame header, an identifier, a cyclic redundancy check code, a high speed signal unit overhead, and at least one slave unit overhead. The high speed signal cell overhead is located before the slave cell overhead. The high-speed signal unit cost is 12 bytes, the slave units 1-n are included in the figure, and the specific number can be set according to actual requirements.
The high speed signal unit overhead and the at least one slave unit overhead are constructed in a parity byte interleaving manner.
Meanwhile, optionally, frame header and CRC8 checks can ensure frame data accuracy, and a 2-byte identifier is used for identifying the direction of issuing and uploading. In the unit overhead, the high-speed signal unit is used as the first unit overhead, so that the main signal of the high-speed signal unit is ensured to be transmitted preferentially under the condition that the frame header, the identifier and the CRC8 of each frame are checked without errors, and the unit overhead of the slave unit can also be used for data coding and transmission according to the priority. All issued control instructions can use odd bytes, uploaded state signals can use even bytes, and each unit overhead is formed in a mode of odd-even byte interleaving, so that communication efficiency and reliability are improved.
Optionally, in the method of this embodiment, when the control unit receives data uploaded from the unit set, the method specifically may include the following steps:
an upload serial frame transmitted from the set of units is acquired.
The uploading serial frame is decoded and processed by protocol frame to generate uploading state signals correspondingly transmitted by each slave unit.
The format of the upload serial frame is the same as the format of the download serial frame, as shown in fig. 4.
Step S103, the issuing serial frame is sent to the slave unit set through the bus, so that the slave unit set sends corresponding data in the issuing serial frame to the corresponding slave unit according to the slave unit identification.
Since the number of the slave units may be more than 2, the slave unit set needs to issue the data in the issued serial frame to the corresponding slave unit, so that the corresponding slave unit can be determined according to the slave unit identifier, and the corresponding data, such as the data in the unit overhead of the slave unit, can be sent to the corresponding slave unit.
According to the serial communication method, the control unit and the slave unit set are connected through the same bus, the same communication protocol is adopted, the control unit can communicate with each slave unit in real time through only one bus, and the signal transmission rate is improved.
Fig. 5 is a schematic flow chart of a serial communication method according to a second embodiment of the present invention, as shown in fig. 5, in which an execution body is a slave unit set based on the serial communication method according to the first embodiment of the present invention. The serial communication method provided by the present embodiment includes the following steps.
Step S201, obtaining at least one upload status signal to be uploaded from the slave unit to the control unit. The upload status signal comprises a slave unit identification.
Each slave unit receives data sent by other devices correspondingly connected, and the slave unit needs to convert the data into an uploading state signal and upload the uploading state signal to the control unit so that the control unit generates a subsequent control instruction according to the uploading state signal.
Step S202, corresponding uploading serial frames are generated according to the uploading state signals.
In this embodiment, the manner of generating the corresponding upload serial frame according to the upload status signal is similar to the manner of generating the corresponding download serial frame according to the control instruction in the control unit.
In this embodiment, data encoding processing and protocol frame processing are required to be performed on the upload status signal to generate a corresponding upload serial frame. The slave unit set may be provided with a data encoding and decoding module for encoding the uploaded status signal and decoding the received serial frame. And a serial protocol frame processing module for processing protocol frames of a preset protocol can be also arranged.
Meanwhile, the slave unit set on the board card can be also provided with a high-speed signal unit, so as to ensure the requirement of the high-speed signal unit on the communication speed.
The transmission priority can be preset for the uploading state signals to be uploaded by the slave unit and the high-speed signal unit, and the preset transmission priority can be set according to the fact that the high-speed signal unit is larger than the slave unit, so that the uploading state signals of the high-speed signal unit are transmitted and processed preferentially, and the communication rate of the high-speed signal unit is improved. Meanwhile, the sending priority can be set for different slave units according to actual demands, so that when the uploading state signal is encoded according to a preset protocol and a preset encoding strategy, the head of the uploading serial frame is encoded with the priority with the highest sending priority.
Step S203, the uploading serial frame is sent to the control unit through the bus, so that the control unit determines the uploading state signal corresponding to the slave unit according to the slave unit identification.
The bus includes a clock line and a serial data line, and the control unit can determine the content of the upload status signal and determine its corresponding slave unit through decoding processing and protocol frame processing after receiving the upload serial frame.
As shown in fig. 3, the control unit and the slave unit are interconnected by a clock line and a serial data frame. The encoding and decoding module encodes and decodes the command issued by the unit to be controlled and the state signal to be uploaded by each slave unit, and encapsulates all data into serial data frames according to a preset protocol frame format so as to realize the control and state monitoring of each unit.
In order to further explain the serial communication method of the present embodiment, a detailed description will be given below with reference to fig. 6. The overall flow of the serial communication method is shown. In the figure, the issued control instruction is abbreviated as an issued instruction, and the issued serial frame and the uploaded serial frame are abbreviated as serial frames. MS0-1 to MS0-12 and MSn-1 to MSn-12 refer to different kinds of signals in the control instruction, SMn-1 to SMn-12 and SM0-1 to SM0-12 refer to different kinds of signals in the upload status signal.
The control unit firstly judges the issued control instruction according to the preset priority, performs data encoding, then sends an issued serial frame to the slave unit set after protocol frame processing, and receives the serial frame from the slave unit set, and then performs frame processing and data decoding to decode the control instruction sent to each slave unit, wherein signals in the control instruction are represented by MS0-1 to MS0-12 and MSn-1 to MSn-12. Meanwhile, after the slave unit sets encode all the uploading state signals corresponding to the slave units according to the preset priority and the protocol frame format, the uploading state signals are sent to the control unit in a serial data frame mode, protocol decoding is carried out after the control unit receives the serial frame, all the uploading state signals corresponding to the slave units are solved, and the signals are represented through SMn-1 to SMn-12 and SM0-1 to SM0-12, so that real-time control and state monitoring are achieved.
