Cable trench operation and maintenance monitoring system

Abstract

The invention provides a cable trench operation and maintenance monitoring system which comprises at least one Mojie node sensor, an Internet of Things (IOT) gateway, a server, a mobile terminal and adistribution network operation and maintenance system, wherein each Mojie sensor comprises a temperature probe, a gas probe, a smoke probe and a liquid level probe, the temperature probe is used formeasuring ambient temperature and cable joint temperature, the gas probe is used for measuring the volume concentration of combustible alkane gas, the volume concentration of hydrogen sulfide H2S gasand the volume concentration of carbon monoxide gas, the smoke probe is used for monitoring the volume concentration of smoke, and the liquid level probe is used for measuring a liquid level depth. Each Mojie sensor is used for obtaining measurement data and sending the data to the IOT gateway. The IOT gateway sends the above data to the server. The terminal and the distribution network operationand maintenance system are used for reading the data from the server. According to the system, a cable trench is continuously monitored online through the sensor, and the problem that the cable trenchcannot be continuously monitored in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a cable trench operation and maintenance monitoring system. Background technique [0002] Due to the closed environment and no low-voltage power supply of electric power underground cable trenches, the real-time monitoring method of GPRS was used in the past. Due to the high power consumption and large sensor volume, a large amount of power consumption is required, so online persistent monitoring cannot be realized, and the big data required for system evaluation cannot be formed. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a cable trench operation and maintenance monitoring system to solve the problems existing in the prior art. [0004] A cable trench operation and maintenance monitoring system provided by the present invention, the system includes at least one magic joint sensor, an Inte...
