Private communication protocol system based on Lora standard base station ad hoc network and method of system

Abstract

The invention discloses a private communication protocol system based on a Lora standard base station ad hoc network and a method of the system, and the method comprises the following steps: firstly enabling a base station to be synchronized to an initialization state; entering the base station, opening a base station table, and detecting whether the base station table is expired or not; if the base station table is not expired, directly starting a synchronization process, then synchronously updating a base station communication priority queue, and if the base station table is expired, initializing the base station, completing self-broadcasting in a network domain, then reconstructing base station table information, and then synchronously updating base station communication priority alignment; after the communication priorities of the synchronously updated base stations are aligned, acquiring a next updating timestamp acquisition token; and completing synchronization after base stationsynchronization completion. The method has the advantages that the communication model is simple and reliable, and the base stations are flexibly networked; multiple frequency bands are reasonably used, and the communication efficiency is improved; and base station realizes plug-and-play.

Description

technical field [0001] The invention relates to the technical field of communication protocol monitoring, in particular to a self-owned communication protocol system and method for a dangerous goods sensor monitoring data transmission based on a wireless network. Background technique [0002] LoRa is a low-power local area network wireless standard created by Semtech Corporation. The name of LoRa is Long Range Radio. Its biggest feature is that it can transmit farther than other wireless methods under the same power consumption condition, realizing the unity of low power consumption and long distance. The consumption is 3-5 times larger than the traditional radio frequency communication distance. [0003] Features of LoRa [0004] Transmission distance: up to 2-5Km in towns and up to 15Km in suburbs. [0005] Working frequency: ISM frequency band includes 433, 868, 915MH, etc. [0006] Standard: IEEE 802.15.4g. [0007] Modulation method: based on spread spectrum techno...

Problems solved by technology

[0012] At present, the main Lora communication system is the communication between the LoraWAN gateway and the Lora node. In order to support various scenarios, the common communication protocol of LoraWAN has a bloated and complex protocol stack and relatively low communication efficiency.

In addition, the price of the general Lora gateway is relatively expensive, and there may be problems in the communication between different gateways.
