Wireless multi-point equalized low-power-consumption power monitoring system and method

Abstract

The invention relates to a wireless sensor network technology and a data acquisition field, and discloses a wireless multi-point equalized low-power-consumption power monitoring system and method. The system comprises a wireless monitoring terminal, common control equipment and upper management software. The innovation point of the system and method lies in that: 1) each wireless monitoring terminal is connected with more than two sensor units, wherein each wireless monitoring terminal uploads an equilibrium value to the common control equipment after equalizing and comparing data acquired by multiple sensor units, thus, the inconvenience in replacing the terminal equipment caused by the damage of the sensor unit is avoided; 2) a special calling mechanism is adopted in each wireless monitoring terminal, and each wireless monitoring terminal is in a low-power-consumption standby state most of time and automatically turns into a working state only after receiving a monitoring command; and 3) the common control equipment selectively sends the received data according to a preset condition. According to the invention, the redundant data in the system is reduced, the safety monitoring efficiency is increased, and the low-power-consumption problem in the wireless monitoring is solved.

Description

technical field [0001] The invention relates to the field of wireless sensor network technology and data collection, in particular to a wireless multi-point balanced low-power power monitoring system based on wireless sensor network technology. Background technique [0002] With the rapid economic growth, the safety problems of my country's high-voltage power grid equipment have become increasingly prominent, and the safe operation monitoring of power equipment has become the key to solving the problem. At present, there are three main monitoring methods adopted to ensure the safe operation of power equipment: optical fiber monitoring, infrared monitoring, and wireless monitoring. The cost of optical fiber monitoring is high, especially in the occasions below 35KV where there are a lot of equipment, it cannot be widely used. Infrared monitoring cannot be continuously monitored online, and cannot measure parameters of non-visible points. Therefore, at present, electric powe...

AI Technical Summary

Problems solved by technology

In the implementation process of the existing method, if the sensor unit is damaged and fails, the entire monitoring terminal will not be able to monitor, and then there will be "blind spots" in the collection area, especially in places that are dangerous at high places or where people are not easy to reach, and it is troublesome to replace the monitoring terminal manually. and difficult to implement

In addition, a large amount of data is directly transmitted to the management machine through the concentrator without "screening", which will easily cause data redundancy

At the same time, the terminal equipment is in the real-time online monitoring state, which will bring unnecessary energy waste
