With the popularization and implementation of unattended substations, it is very important to strengthen environmental monitoring of substations and ensure the safety of power supply. The traditional environmental monitoring system of distribution room is mainly for staff to measure and check the distribution equipment one by one. The result is time-consuming and laborious, which can neither reflect the real situation in time nor solve practical problems in time. Generally, the environmental monitoring system of distribution room takes the environmental temperature and humidity, distribution switch status, water leakage/flooding, smoke and theft prevention of distribution room in low-voltage network as the monitoring objects, and carries out local linkage control, remote centralized monitoring and SMS alarm on various parameters and status of important equipment in distribution room. The system adopts technologies such as Internet of Things and big data processing to realize online monitoring of the operation environment of the distribution room and the state of power equipment, which can improve the operation reliability of the distribution room, thus effectively improving the operation reliability of the whole distribution network.

Achieve the purpose of providing highly stable and reliable monitoring information resources for equipment operation, real-time data monitoring and necessary remote control and intelligent control.

★ Realize fault alarm caused by power distribution fault, notify relevant management personnel in various ways, handle it in time, solve it in time, and give an early warning of upcoming faults.

★ Promote the automation and intelligence of power distribution, clarify the rights and responsibilities of managers, improve the level of power distribution management, save operation and management costs, and achieve the purpose of short-term investment and long-term benefit.

★ Use the perfect data statistics and analysis function of the system to provide reliable reference for the managers of distribution stations and provide sufficient decision-making basis for the construction and improvement of distribution stations.

★ Reserve enough expansion functions to meet development needs, facilitate expansion and change, and adapt to changes in the environment and diversification of management needs.
