Method and system for monitoring cable joint by NB-IOT technology

Abstract

The invention discloses a method and system for monitoring a cable joint by an NB-IOT technology. The method comprises the steps of acquiring a temperature value and a humidity value of the cable joint based on a data acquisition module arranged on the cable joint; realizing data conversion of the temperature value and the humidity value based on an analog-to-digital conversion module on a terminal control module, and generating temperature and humidity acquisition data; and sending the temperature and humidity acquisition data to a cloud platform based on an NB-IOT module. According to the embodiment of the invention, the equipment can monitor the parameter information of the cable joint in real time, and the monitoring information is transmitted through the NB-IoT technology, so that themanpower resources and cost are greatly reduced, and the data obtaining accuracy is improved through the automatic monitoring in the equipment.

Description

technical field [0001] The invention relates to the technical field of power detection, in particular to a method and system for monitoring cable joints using NB-IOT technology. Background technique [0002] With the rapid development of large units, large capacity and high voltage in the power industry, the operating conditions are more harsh, the failure rate is gradually increasing, the troubleshooting time is getting longer and longer, and the economic losses caused are also increasing. The modern power industry is constantly in To change these aspects and study many various technologies to deal with fault problems, wireless temperature measurement technology has become a very important part of monitoring technology in the power industry. Therefore, the power industry at home and abroad has put forward higher and higher requirements for the reliability of wireless temperature measurement power equipment operation. The most important performance is accuracy, real-time and...

Problems solved by technology

[0003] Due to changes in the climate equipment foundation, equipment being polluted by the environment, severe overload operation, contact oxidation and other reasons, the crimping is not tight, the pressure is not enough, the contact part of the contact changes, and finally the contact resistance increases. When the current passes, the temperature increase, which will cause equipment aging, insulation decline, reduce the service life of equipment, and always threaten the safe operation of power equipment. Therefore, it is necessary to provide a corresponding solution for cables
