Linked network wireless high-speed communication protocol

Abstract

The invention discloses a linked network wireless high-speed communication protocol. A linked network consists of management nodes and ordinary nodes, wherein the management nodes are used as a starting point, the wireless communication is used as a medium, and the ordinary nodes are sequentially networked and connected; in a real physical linked network, a link data forwarding address is configured in each node in a single-link, double-link and three-link virtual linking way according to the real requirement; the quick forwarding of the data and the backup function of a forwarding route can be carried out by virtue of the link data forwarding address; three types of data transmission orders such as a broadcast order, a direct transmission order and a lengthening order are only defined by the network nodes, and the transmission requirement of all data among the nodes can be completed. The transmission reliability can be improved by adopting the double-link and three-link linking way, so that the response time of the wireless communication can be shortened, the efficiency for storing and forwarding the uplink data and downlink data of the link data can be improved, the high-speed transmission of data among the link nodes can be realized, and the safety and reliability can be improved.

Description

technical field [0001] The invention relates to the communication field, in particular to a chain network wireless high-speed communication protocol. Background technique [0002] In the fields of the Internet of Things, smart industry, smart transportation, smart lighting, and smart roads, there are a large number of devices that need to be networked and communicated. Most of these networked communication devices are installed in a straight-line link environment. Form a chain network topology structure, realize the communication between equipment and main control, equipment and management center, and complete industrial information collection and control. [0003] At present, all walks of life generally use RS485 bus, CAN bus, power carrier, optical fiber communication and other wired transmission media to realize communication in link-type environmental equipment network communication. This kind of wired network communication needs to spend a lot of wire. The cost of the ...

Problems solved by technology

[0006] The zigbee network and self-organizing network currently in use all adopt dynamic network access and dynamic topology calculation, and it is impossible to establish a backup link. Especially after a key routing node fails, all nodes under it need to re-enter the network and perform topology calculation again. , time-consuming and energy-consuming, and will also cause network access vibration problems, which greatly weakens the stability of the network and increases the risk of data loss during data transmission
