Communication method and system between devices

Abstract

The invention relates to a communication method and system between devices, and the method comprises the steps: S1, enabling a control device to configure an IQ signal parameter in Radio.SetTxConfig in an instruction into different values according to the difference of the types of the instruction to be sent, and then, enabling the control device to send the instruction; the type of the instruction comprises a D2D type and a LoRaWAN type; and S2, receiving the instruction in real time by the controlled equipment, and executing the operation of analyzing the instruction or discarding the instruction according to different IQsignal parameter values in Radio.SetTxConfig in the received instruction. According to the invention, gateways and network servers in the LoRaWAN system are reduced, the delay of data transmission between LoRa devices is reduced, and the real-time performance is high; through polarity switching of the nodes, direct communication between the LoRa nodes is realized.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication method and system between devices. Background technique [0002] LoRaWAN (Long Range Wide Area Network) is a narrow-band low-power wide-area IoT technology that has developed rapidly in recent years. Its network topology is a star network, which is composed of network servers, gateways and terminal nodes. , smart home, smart infrastructure and other aspects are widely used. However, LoRaWAN still has the following problems in node communication: [0003] (1) LoRaWAN technology needs to pass through the gateway when transmitting data and linkage control of other devices, which has a large delay and poor real-time performance; [0004] (2) The communication between nodes depends on the gateway and NS. In the absence of a gateway, there is no direct communication between nodes; [0005] (3) The Class C main control device needs to continue to detect ...
