[0061] Wherein, exemplary, the first data packet is:

[0062] "{'msgNum': '1234', 'Direct': 'D0T1A103', 'srcID': '000001F1P1M1C10100D1', 'dstID': '000001F1P1M1C10100D2', 'regAddr', 'C2H1N1E1', 'regVal': '00_'} ".

[0063] Specifically, the msgNum is the identifier of the data packet.

[0064] The Direct is the data packet type, and T1 indicates that the transmission type is the first transmission type, which is transmitted ...

Embodiment 2

[0090] The embodiment of this application provides a communication method, which is applied to such as figure 1 In the IoT system shown. Hereinafter, the first device is an Internet of Things terminal device D2, the second device is a control terminal device D1, and the second device establishes a relationship between the first device and other Internet of Things terminal devices as an example for illustration.

[0091] Such as image 3As shown, the method includes S301-S304:

[0092] S301. The IoT terminal device generates a seventh data packet, and sends the seventh data packet to a gateway.

[0093] Wherein, the seventh data packet is:

[0094] "{'msgNum': '1234', 'Direct': 'D0T3R103', 'srcID': '000001F1P1M1C10100D2', 'dstID': '000001F1P1M1C10100D1', 'regAddr', 'C5G1M1E6', 'regVal': '05_56789'} ".

[0095] Specifically, the msgNum is the identifier of the data packet.

[0096] The Direct is the data packet type, and T3 indicates that its transmission type is the third...

Embodiment 3

[0111] The embodiment of this application provides a communication method, which is applied to such as figure 1 In the IoT system shown. Hereinafter, the first device is the control terminal device D1, the second device is the Internet of Things terminal device D2, and the unicast control process between the control terminal device and the Internet of Things terminal device is described as an example. The unicast control process is used to close the switch of the executive device relay of the Internet of Things terminal device.

[0112] Such as Figure 4 As shown, the method includes S401-S405:

[0113] S401. The control terminal device generates a tenth data packet, and sends the tenth data packet to a server.

[0114] Wherein, the tenth data packet is:

[0115] "{'msgNum': '1234', 'Direct': 'D0T1B103', 'srcID': '000001F1P1M1C10100D1', 'dstID': '000001F1P1M1C10100D2', 'regAddr', 'C1J1O1E4', 'regVal': '01_1'} ".

[0116] Specifically, the msgNum is the identifier of the ...

Abstract

The invention provides a communication method, which is applied to the field of communication and is used for carrying out data transmission according to a data packet in a preset format. The method comprises the following step of transmitting data between devices in the Internet of Things system through a data packet in a preset format, wherein the data packet in the preset format comprises a data packet identifier, data packet types, a device identifiers, a destination register address and a destination register value; the data packet types comprise a system type, a transmission type, an operation type and an operation result; the device identifiers comprise a first device identifier and a second device identifier, and the first device identifier refers to a source device identifier; thesecond equipment identifier refers to a target equipment identifier; the device identifiers comprise a user number, a region number, a physical grouping type of the device, a physical grouping numberof the device, a device type, a device address type and a device address. Via the communication method and device disclosed in the invention, automatic establishment and automatic control of the Internet of Things system can be realized through the data packet in the preset format.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the prior art, Internet of Things terminal devices of different companies use different Internet of Things protocols, resulting in inability to communicate directly between these devices. Complicated configuration of these devices is required to build a complete IoT system, and then effectively manage and control the devices of the IoT system. After the Internet of Things system is built, if the automatic control function is to be realized, it is also necessary to configure the communication relationship between the Internet of Things terminal devices. When the number of devices in the Internet of Things system is large, the communication relationship between these devices will be Very complicated, which greatly increases the workload of configuration. Contents of the invention [0003] Th...
