World Electric Intelligent Power and Environment Monitoring IoT Solution

❶ Introduction to Power and Environment Monitoring System

Power and Environment Monitoring refers to the centralized monitoring of power equipment and environmental variables in various types of equipment rooms, i.e., Power and Environment Monitoring. A comprehensive integrated Power and Environment Monitoring System can perform remote measurement and remote signaling data acquisition from distributed independent power equipment, room environment, and security monitoring objects. It provides real-time monitoring of system and equipment operation status, records and processes relevant data, promptly detects faults, performs necessary remote control and adjustment operations, and notifies personnel for handling in a timely manner.

❷ Basic Functions Required for a Power and Environment Monitoring System

• Room power equipment is connected to the Power and Environment Monitoring System via intelligent data interfaces (RS232, RS485, RS422) or by adding sensor devices, enabling functions such as monitoring normal operation status, predicting abnormal conditions, and online intelligent fault diagnosis.
• The working environment of power equipment, servers, and transmission/switching equipment, such as temperature, humidity, water leakage, fire protection, and other environmental parameters, as well as room air conditioning monitoring, are integrated into the Power and Environment Monitoring System. This enables real-time data monitoring, alarm threshold setting, alarm prediction, and the implementation of corresponding handling strategies based on emergency plans when alarms occur, ensuring a healthy working environment and providing strong guarantees for reliable equipment operation.
• As a critical area, the security environment of the equipment room must be integrated into the Power and Environment Monitoring System. This includes implementing functions such as access control management, intrusion and theft alarm management, video surveillance, and IP intercom, ensuring room security, enabling remote unattended management, and saving human resources.
• The monitoring system must support flexible networking methods, allowing the construction of monitoring networks based on available on-site resources. It should support networking via field data buses (RS485, RS422, RS232, etc.), TCP/IP, cellular networks, and other methods.
• For dispersed equipment rooms, the principle of distributed application, centralized monitoring, and unified management should be adopted to achieve unattended operation.
