Scene application and monitoring principle:
The monitor is mainly used for urban pipe networks, restricted spaces, sewage pipes, valves In wells, septic tanks and other places, the equipment gathers sensor data and contact signals to the motherboard. After processing and packaging, the data is sent to the monitoring center through the GPRS/4G/NB-IOT wireless module. When the monitoring value is abnormal, the monitoring device will immediately upload alarm information.

series Unified group network topology diagram :
The system is composed of front-end monitoring equipment, transmission network, back-end emergency management platform, etc., to realize online real-time monitoring. Users can use mobile terminals and computers to view the data of the monitoring center.
