Intelligent GPRS data concentrator
The GPRS data concentrator is an indispensable important device in the remote meter reading system, and is the relay station of the Internet of Things water meter system terminal. The uplink uses a GPRS network and a cloud server remote management system network to process commands such as meter read commands and control commands from the remote management system. Downstream, the LoRa ad hoc network is used to send meter reading and switching valve commands to the water meter. In an ideal environment, the GPRS concentrator can be connected to a water meter within 1500 meters. If a small number of water meters cannot be successfully connected, you can use a repeater to enhance the signal.
