Intelligent electricity safety supervision system is a set of early warning and prevention management system innovated by guderian in view of frequent electrical fire accidents in China. The system is based on the technical system of Internet of Things, and is applied to 200V-400V low-voltage distribution system. By monitoring the residual current, current and temperature of key nodes such as distribution cabinets and secondary cabinets, the potential safety hazards existing in the dynamic operation of lines can be grasped in time, which provides a new technology and management concept for improving the whole power safety management level.
(A) the main functions of the system
Local alarm: when the monitoring value is abnormal, the buzzer of the field equipment gives an audible and visual alarm;
Cloud service platform: customers can know the safety situation of enterprise electricity consumption anytime and anywhere through mobile phones or networked computers, and remind all security personnel of potential safety hazards in time through early warning;
Electricity safety report: The platform will regularly send customers the electricity safety situation of monitoring lines, so that customers can easily grasp the electricity situation without sending people on duty;
Professional diagnosis report: provide remote "physical examination" report regularly to serve users to analyze and rectify the causes of hidden dangers in electrical lines;
System remote upgrade and maintenance: continuously enhance system functions; Ensure the stable operation of the system;
Support third-party service hosting, on-site investigation of potential safety hazards, and rectification of electrical circuits.
(2) System composition and characteristics
Intelligent electricity safety monitoring service system consists of intelligent electricity safety sensing terminal, sensing data communication base station and intelligent electricity safety management service platform.
1. Power security intelligent sensing terminal
The intelligent sensing terminal for electricity safety can monitor the residual current, current, conductor temperature and environmental temperature of the power supply line in real time; When the characteristic parameters of power supply line electricity safety reach the alarm value, the alarm signal is immediately transmitted back to the monitoring equipment in real time through wireless transmission, so as to realize the early warning function of electricity safety.
2. Sensing data communication base station
Sensor data communication base station is a device that connects the data of power security intelligent sensor terminals to the Internet to realize remote data transmission.
3. Intelligent power safety management service platform
Remote login by using Web and APP: Users can get real-time information about the safe operation of enterprise electricity consumption by using authorized accounts and passwords through computers or mobile phones with Internet access.
4. Alarm reminder
Real-time display of alarm information of intelligent sensing terminal for electricity safety, including alarm position, type and occurrence time.
The alarm information window pops up.
Graphic display of alarm information
5. Form a test report every week.
The platform regularly counts the electricity consumption data during this period every week and generates a test report. Users can log in to the platform to browse at any time.
Record historical data
Through long-term operation, the changes of residual current and temperature data can be recorded and observed, and the hidden dangers of line power consumption can be grasped in time, which is also conducive to investigating and analyzing the causes of power failure. It can support the query of power consumption data in any time period.
7. Automatic reminder by SMS or email
The platform can customize the reminder mode and content according to customer requirements.
8. Platform operation and maintenance
It can know the running state of the intelligent sensing terminal equipment in real time, and the company's maintenance personnel will notify relevant personnel to deal with it in time after the failure occurs.
