Problems solved by technology

[0002] With the continuous advancement of urbanization, more and more buildings stand around us. Nowadays, almost all kinds of office, commercial and residential buildings generally adopt the underground floor as the power distribution room design, but the underground floor is deep underground. Tens of meters away and blocked by thick concrete walls, telecom operators' network signals cannot be covered or only have weak signals, and various intelligent monitoring equipment cannot directly apply 3G / 4G communication networks for data transmission; method, high construction cost, difficult operation and maintenance, and poor expansion flexibility

The effective transmission distance of commonly used wireless sensing technology signals is short, and the electromagnetic environment inside the power distribution room is complex, and the operating environment of the equipment is very different from that on the ground. The traditional wireless communication method on the ground is greatly limited in the basement power distribution room and is difficult to realize. Stable and reliable data communication

Common devices that use Bluetooth, WIFI, and other wireless communication methods for online monitoring have the problem of excessive power consumption, and need to lay dedicated power supply lines, basically losing the advantages of wireless communication.

[0003] In order to solve the problems of weak mobile network signal coverage, difficult wired sensor wiring, wireless sensor power consumption and transmission stability in the basement power distribution room, the present invention proposes a wireless sensor monitoring system for an ultra-low power consumption basement power distribution room The technology based on RFID and LoRaMESH uses multiple sensors to comprehensively monitor the environment of the power distribution room in the basement, and at the same time manages the power consumption of the work of various wireless sensors, thereby realizing comprehensive monitoring of the environment under ultra-low power consumption
