Real-time monitoring system and method for environment of whole-network communication terminal boxes

Abstract

The invention discloses a real-time monitoring system and method for the environment of whole-network communication terminal boxes. The system comprises an environment detection collecting unit, a system master control unit, a whole-network communication unit, a linkage relay unit and a background management system; the environment detection collecting unit collects and monitors environmental parameters of the terminal boxes, collected environmental data is sent to the system master control unit to judge whether or not the environmental data is normal, when the data is abnormal, the linkage relay unit is triggered to control execution equipment to adjust the environmental parameters, meanwhile, through the whole-network communication unit, the environmental data and alarm information are transmitted to the background management system, the background management system monitors the operation conditions of all the front end terminal boxes in real time, through a background electronic map, the terminal box with abnormal alarming is rapidly positioned, and information is sent to mobile phone terminal equipment. Communication between the system master control unit and the whole-networkcommunication unit includes LoRa, Zigbee, NBIoT, WiFi, RJ45, CAN, RS485, GPRS and 4G.

Description

technical field [0001] The present invention relates to the technical field of power equipment monitoring, and specifically refers to a system and method for real-time monitoring of the environment of a full-network terminal box. Background technique [0002] In the substation, the terminal box is the intermediate link between outdoor electrical equipment and indoor protection, measurement and control, and communication equipment. The dual functions of measurement and protection, whether its operating status is good or not directly affects the safety of power system operation and the stability of power supply. [0003] Condition monitoring of the environment of the substation terminal box is one of the effective means to improve the safe and stable operation of the power system. At present, the following two schemes are usually used to monitor the environment of the terminal box in the existing technology: ①The temperature controller method: add a heating plate and an exhau...

AI Technical Summary

Problems solved by technology

At present, the following two schemes are usually used to monitor the environment of the terminal box in the existing technology: ①The temperature controller method: add a heating plate and an exhaust fan to the terminal box, and automatically control it through the temperature controller, and the staff cannot control it in time. The heater and fan are often damaged due to continuous work for a long time, but they do not know it, which leads to various accidents in the terminal box; ②The temperature and humidity are monitored through wired (bus, Ethernet) or wireless (GPRS, WIFI, Zigbee) methods : At present, most of the products on the market only monitor temperature and humidity, with a single monitoring parameter and no follow-up linkage processing unit

Method 1 does not upload parameters and can only monitor temperature and humidity parameters, so the staff cannot grasp the specific conditions of the terminal box in real time; method 2 can upload data, but the monitoring parameters (only temperature and humidity) are single, and the transmission method is not comprehensive enough (mainly Ethernet, WIFI, Zigbee, GRPS), and no linkage processing unit, only simple monitoring of temperature and humidity parameters
