Description

Multichannel wireless communication equipment and management method Technical Field The present invention relates to the field of wireless communications, and in particular, to a multi-channel wireless communications device and a management method. Background With the continuous development of the internet of things technology, a large number of terminal devices perform remote data transmission through a low-power-consumption wide area network. The LoRa technology is widely applied in the fields of industrial monitoring, intelligent agriculture, urban infrastructure management, environmental data acquisition and the like due to the advantages of wide coverage range, low power consumption, flexible networking and the like. In a typical application scenario, the system generally adopts a star network structure, and a central node centrally manages communications of a plurality of terminal nodes. In the prior art, a central node mostly adopts a single loRa module to transmit and receive data, and organizes a terminal to report the data in a time-sharing scheduling or simple broadcast control mode. This structure can satisfy the basic communication requirement when the number of terminals is small. However, under the conditions that the terminal scale is continuously enlarged, the data uploading frequency is increased or the application environment is complex, the problems of channel congestion, data collision, increased packet loss rate and the like easily occur in the single-channel structure. Meanwhile, since the central node has only a single path receiving capability, a collision is easily generated when a plurality of terminals answer at the same time, resulting in a decrease in communication efficiency. Furthermore, existing schemes have limitations in terms of expansion capabilities. When it is desired to promote the concurrency capability of a system, it is often necessary to add independent equipment or build a multi-level network structure, increasing the complexity of the system and the deployment cost. Disclosure of Invention The technical problem to be solved by the invention is to provide a multichannel wireless communication device and a management method, which can improve concurrency capability of a system. In order to solve the technical problems, the invention adopts the following technical scheme: A method of managing a multi-channel wireless communication device, comprising the steps of: s1, starting a first preset number of LoRa modules in multichannel wireless communication equipment, wherein the first preset number is more than or equal to 2; S2, setting a second preset number of LoRa modules as a main channel, wherein the second preset number is smaller than or equal to the first preset number; s3, controlling the LoRa module serving as the main selection channel to poll and send broadcast data according to a preset interval; And S4, after any one of the LoRa modules transmits the broadcast data to the terminal equipment, controlling all the LoRa modules to enter a receiving mode and waiting for the terminal equipment to return the communication data. In order to solve the technical problems, the invention adopts other technical schemes as follows: a multi-channel wireless communication device, a management method applied to the multi-channel wireless communication device, the device comprising: A main control chip; the LoRa modules are in communication connection with the main control chip, and the number of the LoRa modules is more than or equal to two; and the transceiver is in communication connection with the main control chip. The multi-channel wireless communication device and the management method have the beneficial effects that the multi-channel wireless communication device and the management method are provided, and a management mechanism of multi-module cooperative work is realized by starting at least two LoRa modules in the multi-channel wireless device, setting part of the LoRa modules as main channels according to actual requirements and adopting a polling broadcast and unified receiving control mode. The method is characterized in that a plurality of LoRa modules exist in parallel, but broadcast is sent through polling at preset intervals, so that each main channel works orderly in the time dimension, and the conflict caused by simultaneous active sending is avoided. Meanwhile, after any main selection module broadcasts, all modules are controlled to enter a receiving state, which is equivalent to forming a multipath parallel receiving structure, and the capturing probability of terminal response data is improved. The method effectively solves the problems of the traditional single-channel structure that the packet loss rate rises and congestion occur when the number of nodes is increased, and improves the overall throughput capacity and the identification efficiency of the system.
