Novel dual-channel wireless communication system, control method and control system

Abstract

The invention provides a novel dual-channel wireless communication system, a control method and a control system. The dual-channel wireless communication system comprises an intelligent gateway, a sensor terminal and an electric power big data platform, and the intelligent gateway is connected with the sensor terminal and the electric power big data platform; the intelligent gateway is provided with a first wireless communication channel and a second wireless communication channel; the first wireless communication channel works in an active uploading mode, and monitors report information actively sent by the sensor terminal when the first wireless communication channel is idle; and the second wireless communication channel collects data of the sensor terminal in a normal polling mode. The system has the advantages that automatic registration and network access of the sensor can be supported, the wireless communication frequency and the communication ID are automatically allocated to the sensor, and configuration steps are simplified; and due to the fact that the independent active uploading channel is used, when the sensor generates the alarm information, the sensor can be actively switched to the active uploading communication wireless frequency to upload the alarm information, and the problem of alarm information transmission delay is solved.

Description

technical field [0001] The present invention relates to the technical field of ubiquitous power Internet of Things communication, and in particular to a novel dual-channel wireless communication system, a control method and a control system. Background technique [0002] The goal of ubiquitous power Internet of Things construction is to build a multi-level system communication architecture of cloud, pipe, edge, and terminal, to realize comprehensive perception of terminal information, localized data processing, and efficient information transmission, and to establish a unified power big data processing platform. , and based on this, carry out big data analysis, mine data value, and carry out various businesses. More and more sensors transmit data to the smart gateway through wireless communication, and the smart gateway uploads the data to the power big data processing platform through the Internet of Things communication protocol. [0003] The wireless communication method...

AI Technical Summary

Problems solved by technology

[0003] The wireless communication method has the advantages of convenient equipment installation and low construction cost, but the problem is that the sensors of the short-range wireless communication method generally adopt a question-and-answer communication protocol, and the intelligent communication gateway needs to poll one by one to collect data from multiple sensor terminals. Fault and alarm information cannot be read and uploaded to the power big data processing platform in time. The transmission delay of this key information may lead to the expansion of on-site accidents; on the other hand, the site should reasonably divide the wireless communication channel frequencies of intelligent communication gateways and sensor terminals Communicate with the sensor ID to avoid wireless frequency interference and communication ID conflicts. Due to the large number of gateways and sensors, the workload of debugging personnel is increased, and the debugging efficiency is low.
