1. Background overview
In recent years, with the development and popularization of the Internet of Things technology, the construction of smart cities has also entered a new stage. The construction of smart cities is based on the Internet of Things, big data, cloud computing and other information technologies to achieve urban management. Standardization, digitization, and intelligence create a convenient, efficient and comfortable living environment for community residents. As the foundation of the operation of power supply equipment, the low-voltage distribution network is mainly responsible for the control, protection, measurement, and distribution of electric energy. The stability and reliability of the low-voltage distribution network are directly related to the reliability of electricity use. As a new type of power distribution equipment, the intelligent power distribution cabinet has greatly improved the safe operation of the low-voltage distribution network, and provided a strong guarantee for the power consumption of enterprises, making the power supply in people’s lives more and more The more convenient.
2. System overview The
low-voltage electrical cabinet monitoring system realizes the "intelligent cloud operation and maintenance" of the low-voltage electrical cabinet, an intelligent analysis system based on cloud platform WEB and APP, real-time monitoring, intelligent analysis and online operation and maintenance, and real-time monitoring is provided Real-time and historical online data monitoring function; intelligent analysis provides analysis and reports including data, reports, fault warning, power quality and energy efficiency; online operation and maintenance realizes online repair, online monitoring, fault analysis, maintenance management, etc. Provides a web-based data monitoring service based on a cloud platform, which can quickly lock faults in real time through APP, so as to deal with faults in time, reduce the impact of faults on enterprise production and reduce losses.
3. Industrial gateway selection
Chenmai Smart M23F5 is a smart monitoring gateway for the Internet of Things, which uses the public NB-IoT network to realize real-time monitoring of the operating status and environment of various remote front-end equipment, such as: network, power supply, temperature, humidity , Flooding, unpacking alarm, etc., effectively solve the problems of untimely detection of front-end equipment failures and delayed failure processing.
4. Intelligent power distribution cabinet system function
1. With network communication as the core, it completes the collection and monitoring of station-side branch voltage, current, bus temperature, audio and video, environmental data, and safety precautions, and transmits the above information to monitoring Center.
2. On-line monitoring of equipment operating parameters, environment, video, ventilation, lighting, safety protection, fire protection, primary equipment auxiliary monitoring and other monitoring variables are integratedly displayed and controlled on the main interface of the monitoring system.
3. You can set up the linkage between the environmental monitoring, video monitoring, air conditioning and equipment linkage in the system, and complete automatic closed-loop control and alarms according to site requirements, such as automatically turning on/off the air conditioner, automatically turning on/off the fan , Automatically start/close the drainage system, etc.
4. Support mobile terminal access, users can access platform data through mobile devices such as mobile phones and PAD, and manually control front-end equipment.
5. All operations and alarm confirmation need to keep detailed logs and generate corresponding reports
6. The system can upload station-side data to the central platform in real time and accept remote control instructions. It can also operate in isolation without interference through the pre-configured linkage scheme to ensure the normal operating environment in the power distribution room.
V. System value
1) Improve the management efficiency of the power distribution room and reduce the cost of operation management.
Real-time monitoring of the environmental data and equipment operation status of the power distribution room, unified management of the on-site electrical equipment, eliminating the tedious work of staff on site inspections, The staff can fully grasp various information of the power distribution room in the monitoring room.
2) Improve the level of comprehensive power management.
Intelligent power distribution cabinets provide management departments with functions such as power cost and efficiency management, power operation dispatch management, and assist managers in adjusting operation strategies and energy use strategies, while achieving improved power operation dispatch Efficiency, the management purpose of reducing the salary cost of on-duty personnel.
3) Save electricity expenses and realize refined management. The
system provides functions such as household metering, bill settlement, peak, flat and valley electricity metering, and various related report data, which are conducive to the refined management of enterprise electricity expenses.
