Remote monitoring system for temperature and humidity of multiple power cabinets

Abstract

The invention discloses a remote monitoring system for temperature and humidity of multiple power cabinets. The remote monitoring system comprises a temperature and humidity sensor, a wireless temperature and humidity collector, a base station, a database, a central management server and a supervision platform, the wireless temperature and humidity collector, the base station and the central management server are wirelessly connected through an narrowband Internet of Things; the database is connected with the central management server and is used for storing the transmitted data for a long time; the supervision platform is connected with the central management server and is used for receiving, analyzing, processing and displaying the temperature and humidity data of each power cabinet; andindependent batteries are arranged in the wireless temperature and humidity collector and the temperature and humidity sensors, and each temperature and humidity sensor is provided with a different and unique identity number and preset with a sending period. Data is transmitted through the narrow-band Internet of Things, different numbers are preset for different wireless temperature and humiditycollectors, and the data is periodically transmitted, so that the effects of reducing the power consumption of the monitoring system, prolonging the service life and quickly processing the power cabinet are achieved.

Description

technical field [0001] The invention relates to the technical field of substation auxiliary equipment, in particular to a remote monitoring system and method for temperature and humidity of multiple power cabinets. Background technique [0002] The outdoor cabinets of the substation have no ventilation equipment and are in harsh environments such as wind, rain, and exposure, and are greatly affected by ambient temperature and humidity. In order to ensure the safe and reliable operation of the wire core, it is necessary to set up monitoring equipment for real-time monitoring, otherwise it cannot be found in time. Faults can easily cause the temperature and humidity in the cabinet to exceed the standard, affecting the safe operation of the equipment. Reference CN208559942U discloses a substation outdoor cabinet state monitoring platform, and CN205484661U discloses a switchgear online monitoring system, all of which realize monitoring of cabinets under various harsh environment...

[0002] The outdoor cabinets of the substation have no ventilation equipment and are in harsh environments such as wind, rain, and exposure, and are greatly affected by ambient temperature and humidity. In order to ensure the safe and reliable operation of the wire core, it is necessary to set up monitoring equipment for real-time monitoring, otherwise it cannot be found in time. Faults can easily cause the temperature and humidity in the cabinet to exceed the standard, affecting the safe operation of the equipment

Reference CN208559942U discloses a substation outdoor cabinet state monitoring platform, and CN205484661U discloses a switchgear online monitoring system, all of which realize monitoring of cabinets under various harsh environmental conditions by means of sensing technology and wireless communication technology. Remote online monitoring and early warning of temperature changes is convenient for maintenance personnel to fully and timely grasp the temperature and humidity conditions of cabinets. However, the monitoring system has high power consumption and cannot handle multiple monitoring points at the same time, which has certain limitations and causes inconvenience in later management.
