技术领域technical field
本发明涉及物联网领域，特别涉及一种数据传输方法、装置及系统。The present invention relates to the field of the Internet of Things, in particular to a data transmission method, device and system.
背景技术Background technique
在物联网领域中，局域网包括中心网关以及与该中心网关连接的多个终端，终端通常处于睡眠状态，每个终端可以每隔一定时长从睡眠状态进入唤醒状态，并向中心网关发送心跳信号。该中心网关在接收到终端发送的心跳信号后，若确定需要进行数据更新，则可以向该终端发送更新数据。若确定不需要进行数据更新，则可以向该终端发送心跳响应，以使终端在接收到该心跳响应后从唤醒状态进入睡眠状态。In the field of the Internet of Things, the local area network includes a central gateway and multiple terminals connected to the central gateway. The terminal is usually in a sleep state, and each terminal can wake up from the sleep state at regular intervals and send a heartbeat signal to the central gateway. After receiving the heartbeat signal sent by the terminal, the central gateway can send update data to the terminal if it determines that data update is required. If it is determined that no data update is required, a heartbeat response may be sent to the terminal, so that the terminal enters a sleep state from the wake-up state after receiving the heartbeat response.
但是，在上述方案中，中心网关需要逐个向多个终端发送更新数据，因此数据传输的灵活性较差。However, in the above solution, the central gateway needs to send update data to multiple terminals one by one, so the flexibility of data transmission is poor.

The identifier of the first terminal is used to uniquely identify the first terminal. Optionally, the identifier of the first terminal may be the address of the first terminal, or may also be the serial number of the first terminal.
在本发明实施例中，该第一终端通常处于睡眠状态，且以心跳方式与中心网关保持连接，该第一终端可以每隔第四时长从睡眠状态进入唤醒状态，并向中心网关发送携带第一终端的标识的第一心跳信号。该第四时长可以为第一终端预先存储的固定时长，示例的，该第四时长可以为1小时。In this embodiment of the present invention, the first terminal is usually in a sleep state and keeps connected with the central gateway in a heartbeat manner.

The second heartbeat signal is a heartbeat signal received by the second terminal within the first time period after the central gateway determines that data update is required. Optionally, the identifier of the second terminal may be the address of the second terminal, or may also be the serial number of the second terminal.
步骤509、中心网关将第二时长以及更新数据的标识发送至第二终端，并记录第二终端的标识。Step 509, the central gateway sends the second duration and the identifier of the updated data to the second terminal, and records the identifier of the second terminal.

Wherein, the second duration is shorter than the first duration, and the start moment of the second duration is the moment when the central gateway receives the second heartbeat signal, and the end moment of the second duration is the same as that of the first duration.
步骤510、第二终端检测是否存储有更新数据。Step 510, the second terminal detects whether update data is stored.
在本发明实施例中，第二终端中存储有中心网关发送的多个数据以及每个数据的标识，在接收到中心网关发送的更新数据的标识后，第二终端可以将该更新数据的标识与其存储的多个数据的标识进行比较，若第二终端存储该更新数据的标识，表明第二终端存储有该更新数据，则第二终端可以执行步骤511。若第二终端未存储该更新数据的标识，表明第二终端未存储该更新数据，则可以执行步骤512。In the embodiment of the present invention, the second terminal stores a plurality of data sent by the central gateway and the identifier of each data, and after receiving the identifier of the updated data sent by the central gateway, the second terminal can store the identifier of the updated data Compared with the identifiers of multiple data stored by it, if the second terminal stores the identifier of the updated data, which indicates that the second terminal stores the updated data, the second terminal may execute step 511 .

步骤512、第二终端保持第二时长的睡眠状态。Step 512, the second terminal maintains a sleep state for a second duration.
第二终端在确定未存储有更新数据后，可以从唤醒状态再次进入睡眠状态，并在保持第二时长的睡眠状态后再次进入唤醒状态。其中，该第二时长小于第四时长。After determining that no update data is stored, the second terminal may enter the sleep state again from the wake-up state, and enter the wake-up state again after staying in the sleep state for a second length of time. Wherein, the second duration is less than the fourth duration.
需要说明的是，在第一时长内，中心网关可以接收到多个第二终端发送的多个第二心跳信号，每个第二终端向中心网关发送的第二心跳信号可以携带该第二终端的标识，中心网关接收到多个第二终端发送的第二心跳信号的时刻可以不同，也可以相同。若中心网关接收到不同第二终端发送的第二心跳信号的时刻不同，则该不同第二终端在确定未存储有更新数据的后，保持睡眠状态的时长不同，且该不同第二终端从睡眠状态再次进入唤醒状态的时刻(从睡眠状态再次进入唤醒状态的时刻也即是唤醒时刻)是相同的，该唤醒时刻与第一时长的终止时刻相同，也即是该多个第二终端均在第一时长的终止时刻从睡眠状态再次进入唤醒状态。It should be noted that within the first duration, the central gateway may receive multiple second heartbeat signals sent by multiple second terminals, and the second heartbeat signal sent by each second terminal to the central gateway may carry the second terminal heartbeat signal. The time when the central gateway receives the second heartbeat signals sent by multiple second terminals may be different or the same. If the central gateway receives the second heartbeat signals sent by different second terminals at different times, the different second terminals will keep the sleep state for different periods after determining that there is no update data stored, and the different second terminals will start from sleep. The time when the state enters the wake-up state again (the time when the sleep state enters the wake-up state again is the wake-up time) is the same, and the wake-up time is the same as the end time of the first duration, that is, the plurality of second terminals are all in At the end of the first duration, the sleep state enters the wake-up state again.

在本发明实施例中，该更新数据可以包括数据包总数。在到达第一时长的终止时刻后，中心网关可以基于第一终端的标识和第二终端的标识，将数据包总数同步传输至第一终端和第二终端。相应的，该第一终端和该第二终端均在到达第一时长的终止时刻后，从睡眠状态再次进入唤醒状态，并接收中心网关发送的数据包总数。In this embodiment of the present invention, the update data may include the total number of data packets. After reaching the termination moment of the first duration, the central gateway may synchronously transmit the total number of data packets to the first terminal and the second terminal based on the identifier of the first terminal and the identifier of the second terminal. Correspondingly, both the first terminal and the second terminal enter the wake-up state again from the sleep state after reaching the end time of the first duration, and receive the total number of data packets sent by the central gateway.
可选的，中心网关还可以将更新数据的标识同步传输至第一终端和第二终端。Optionally, the central gateway may also synchronously transmit the identification of the updated data to the first terminal and the second terminal.
步骤514、中心网关基于第一终端的标识和第二终端的标识，将多个数据包分多次同步传输至第一终端和第二终端。In step 514, the central gateway transmits multiple data packets synchronously to the first terminal and the second terminal based on the identifier of the first terminal and the identifier of the second terminal.
在本发明实施例中，该更新数据还可以包括多个数据包和每个数据包的传输次序号。中心网关还可以基于第一终端的标识和第二终端的标识，将该多个数据包分多次同步传输至第一终端和第二终端。In this embodiment of the present invention, the update data may also include a plurality of data packets and a transmission sequence number of each data packet. The central gateway may also transmit the plurality of data packets to the first terminal and the second terminal synchronously in multiple times based on the identifier of the first terminal and the identifier of the second terminal.
可选的，对于该多个数据包中的目标数据包，中心网关在每次向第一终端和第二终端同步传输该目标数据包时，可以向第一终端和第二终端同步传输该目标数据包和该目标数据包的传输次序号。也即是，对于每一个数据包，中心网关可以向第一终端和第二终端多次传输该数据包。其中，该目标数据包为多个数据包中的任一数据包，该传输次序号不大于次数阈值。示例的，该次数阈值可以为2。若传输次序号为1，该传输次序号表示中心网关是第1次向第一终端和第二终端同步传输该目标数据包。Optionally, for the target data packet in the plurality of data packets, the central gateway may synchronously transmit the target data packet to the first terminal and the second terminal each time the target data packet is synchronously transmitted to the first terminal and the second terminal. The data packet and the transmission sequence number of the target data packet. That is, for each data packet, the central gateway may transmit the data packet to the first terminal and the second terminal multiple times. Wherein, the target data packet is any data packet in a plurality of data packets, and the transmission sequence number is not greater than the number of times threshold. For example, the times threshold may be 2. If the transmission sequence number is 1, the transmission sequence number indicates that the central gateway is synchronously transmitting the target data packet to the first terminal and the second terminal for the first time.
相应的，以第一终端为例，对于多个数据包中的目标数据包，第一终端在接收到中心网关传输的目标数据包以及该目标数据包的传输次序号后，可以检测接收到的数据包的个数是否小于数据包总数，以及该目标数据包的传输次序号是否小于次数阈值。若接收到的数据包的个数不大于数据包总数，且该目标数据包的传输次序号小于次数阈值，则第一终端保持第三时长的睡眠状态后接收中心网关传输的目标数据包的下一个数据包。若接收到的数据包的个数不大于数据包总数，且该目标数据包的传输次序号等于次数阈值，则第一终端接收中心网关传输的目标数据包的下一个数据包。其中，该第三时长为该目标数据包的传输时长与差值阈值的乘积，该差值阈值为次数阈值与目标数据包的传输次序号的差值，该第三时长小于第四时长。Correspondingly, taking the first terminal as an example, for a target data packet among multiple data packets, after receiving the target data packet transmitted by the central gateway and the transmission sequence number of the target data packet, the first terminal can detect the received Whether the number of data packets is less than the total number of data packets, and whether the transmission sequence number of the target data packet is less than the number of times threshold. If the number of data packets received is not greater than the total number of data packets, and the transmission sequence number of the target data packet is less than the number of times threshold, then the first terminal maintains a sleep state of a third duration and then receives the next target data packet transmitted by the central gateway. a packet. If the number of received data packets is not greater than the total number of data packets, and the transmission sequence number of the target data packet is equal to the number of times threshold, the first terminal receives the next data packet of the target data packet transmitted by the central gateway. Wherein, the third duration is the product of the transmission duration of the target data packet and a difference threshold, the difference threshold is the difference between the number of times threshold and the transmission sequence number of the target data packet, and the third duration is smaller than the fourth duration.
以第一终端为例，示例的，若数据包总数为10，目标数据包为该10个数据包中的第一个数据包，次数阈值为2，则中心网关向该第一终端发送数据包总数10，并在第一次向第一终端传输该第一个数据包时，向该第一终端传输该第一个数据包以及该第一个数据包的传输次序号1。Take the first terminal as an example. For example, if the total number of data packets is 10, the target data packet is the first data packet in the 10 data packets, and the number of times threshold is 2, then the central gateway sends data packets to the first terminal The total number is 10, and when the first data packet is transmitted to the first terminal for the first time, the first data packet and the transmission sequence number 1 of the first data packet are transmitted to the first terminal.
若第一终端接收到该第一个数据包以及传输次序号1，由于第一终端接收到的数据包的个数1小于数据包总数10，且传输次序号1小于次数阈值2，则第一终端可以保持第三时长的睡眠状态。中心网关在第二次向第一终端传输该第一个数据包时，向该第一终端传输该第一个数据包以及该第一个数据包的传输次序号2，由于此时第一终端处于睡眠状态，则第一终端不会接收中心网关第二次发送的该第一个数据包以及传输次序号2。在到达第三时长的终止时刻后，第一终端从睡眠状态进入唤醒状态，并继续接收中心网关发送的第二个数据包，以此类推，直至中心网关将10个数据包均传输至第一终端。If the first terminal receives the first data packet and the transmission sequence number 1, since the number 1 of the data packets received by the first terminal is less than the total number of data packets 10, and the transmission sequence number 1 is less than the number of times threshold 2, the first The terminal may maintain a sleep state for a third duration. When the central gateway transmits the first data packet to the first terminal for the second time, it transmits the first data packet and the transmission sequence number 2 of the first data packet to the first terminal, because at this time the first terminal In the sleeping state, the first terminal will not receive the first data packet and the transmission sequence number 2 sent by the central gateway for the second time. After reaching the termination moment of the third duration, the first terminal enters the wake-up state from the sleep state, and continues to receive the second data packet sent by the central gateway, and so on, until the central gateway transmits all 10 data packets to the first terminal. terminal.
若第一终端未接收到该第一个数据包以及传输次序号1，则第一终端继续接收中心网关第二次发送的第一个数据包以及该第一个数据包的传输次序号2，之后，若第一终端接收到中心网关第二次发送的该第一个数据包和该第一个数据包的传输次序号2，由于第一终端接收到的数据包的个数1小于数据包总数10，且传输次序号2等于次数阈值2，则第一终端可以保持唤醒状态并等待接收中心网关发送的第二个数据包。若第一终端仍未接收到中心网关第二次发送的该第一个数据包和该第一个数据包的传输次序号2，表明第一终端未接收到中心网关发送的第一个数据包，则可以保持唤醒状态并等待接收中心网关发送的第二个数据包，以此类推，直至中心网关将10个数据包均传输至第一终端。If the first terminal does not receive the first data packet and the transmission sequence number 1, the first terminal continues to receive the first data packet sent by the central gateway for the second time and the transmission sequence number 2 of the first data packet, After that, if the first terminal receives the first data packet sent by the central gateway for the second time and the transmission sequence number 2 of the first data packet, since the number 1 of the data packets received by the first terminal is less than the data packet The total number is 10, and the transmission sequence number 2 is equal to the number of times threshold 2, then the first terminal can stay awake and wait to receive the second data packet sent by the central gateway. If the first terminal has not received the first data packet sent by the central gateway for the second time and the transmission sequence number 2 of the first data packet, it indicates that the first terminal has not received the first data packet sent by the central gateway , you can stay awake and wait to receive the second data packet sent by the central gateway, and so on until the central gateway transmits all 10 data packets to the first terminal.
在本发明实施例中，该更新数据还可以包括每个数据包的标识，该数据包的标识可以为该数据包的名称。中心网关在将多个数据分多次同步传输至第一终端和第二终端后，可以向第一终端和第二终端发送更新信息获取指令，以使第一终端和第二终端将更新信息发送至中心网关，中心网关将接收到的第一终端发送的更新信息和第二终端发送的更新信息发送至上位机，由上位机确定是否需要再次向第一终端和第二终端传输更新数据。其中，更新信息可以包括第一终端和第二终端接收到的数据包个数以及接收到的每个数据包的标识。第一终端和第二终端在将更新信息发送至中心网关后，再次进入睡眠状态，并保持第四时长的睡眠状态后再次执行步骤501。In this embodiment of the present invention, the update data may further include an identifier of each data package, and the identifier of the data package may be the name of the data package. After the central gateway synchronously transmits multiple data to the first terminal and the second terminal, it can send an update information acquisition instruction to the first terminal and the second terminal, so that the first terminal and the second terminal will send the update information to To the central gateway, the central gateway sends the received update information sent by the first terminal and the updated information sent by the second terminal to the host computer, and the host computer determines whether to transmit update data to the first terminal and the second terminal again. Wherein, the update information may include the number of data packets received by the first terminal and the second terminal and the identifier of each received data packet. After sending the update information to the central gateway, the first terminal and the second terminal enter the sleep state again, and perform step 501 again after maintaining the sleep state for a fourth period of time.
需要说明的是，中心网关可以采用广播的方式向第一终端和第二终端同步传输多个数据包，在该过程中，中心网关会向第一终端和第二终端传输每个数据包，但是容易理解，第一终端和第二终端可能会接收到中心网关发送的所有数据包，也可能仅会接收到中心网关传输的部分数据包。It should be noted that the central gateway may transmit multiple data packets synchronously to the first terminal and the second terminal in a broadcast manner. During this process, the central gateway will transmit each data packet to the first terminal and the second terminal, but It is easy to understand that the first terminal and the second terminal may receive all the data packets sent by the central gateway, or may only receive part of the data packets transmitted by the central gateway.
在本发明实施例中，由于对于每一个数据包，中心网关会向第一终端多次传输该数据包，因此有助于提高第一终端接收到每个数据包的可靠性以及准确性。并且，由于第一终端在接收到数据包后，若传输次序号小于次数阈值，则该第一终端进入睡眠状态，并在中心网关传输下一个数据包时从睡眠状态进入唤醒状态，因此第一终端无需一直保持唤醒状态，有助于降低第一终端的功耗。In the embodiment of the present invention, since the central gateway will transmit the data packet to the first terminal multiple times for each data packet, it is helpful to improve the reliability and accuracy of each data packet received by the first terminal. And, because after the first terminal receives the data packet, if the transmission sequence number is less than the number of times threshold, the first terminal enters the sleep state, and enters the wake-up state from the sleep state when the central gateway transmits the next data packet, so the first terminal The terminal does not need to keep in the wake-up state all the time, which helps to reduce the power consumption of the first terminal.
需要说明的是，本发明实施例提供的数据传输方法步骤的先后顺序可以进行适当调整，步骤也可以根据情况进行删除。例如，步骤503、步骤504以及步骤511可以根据情况删除。任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化的方法，都应涵盖在本发明的保护范围之内，因此不再赘述。It should be noted that the order of the steps of the data transmission method provided in the embodiment of the present invention can be adjusted appropriately, and the steps can also be deleted according to the situation. For example, step 503, step 504 and step 511 may be deleted according to circumstances. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changing methods, which should be covered within the scope of protection of the present invention, and thus will not be repeated here.
