  • Solution of IOT Cellular Modem
  •  

Install a monitoring terminal box at the monitoring point, which is equipped with a data acquisition terminal that can be directly connected to the flowmeter and other instruments. After the wireless data transmission module is powered on, it will automatically report monitoring data (such as traffic, etc.) to the data management system server of the monitoring center through the GPRS/4G network according to the set test interval.
The computer room of the monitoring center is equipped with a dedicated server computer, and the server is equipped with remote monitoring system software and server system for groundwater level. Realize the sending and receiving of data collected at the monitoring point and real-time monitoring and management of status through RTU ZHC4921.
