Photoelectric direct reading cable remote meter reading meter system consists of photoelectric direct reading water meter, collector, concentrator, remote meter reading platform. The system supports 2 levels of networking. The water meter is directly connected to the downstream bus interface of the concentrator through the m-bus bus. The concentrator sends data to the server through the uplink GPRS interface. The system supports the 3-level network water meter directly connected to the m-bus bus. The downstream bus interface of the collector, each collector can be connected to multiple water meters, the collector is connected to the concentrator through the uplink 470MHZ wireless interface, each concentrator is connected to multiple collectors, and the concentrator sends data to the server through the uplink GPRS interface.
