The automatic meter reading system is comprised of management software, concentrator and AMR meters of water, electricity, gas and heat.
Systems introduction & application
Integrated with smart meters, computer technology and network communication technology, this automatic meter reading system gathers data from meters on real time/ timing, saves and analyzes the data for practical application.
Based on analysis and statistics of data from meters, information networking, self-assist search, data report can be implemented according to customer requirements. Managing demands of billing system, arrearage management and so on are also can be implemented. Meters belong to defaulting subscriber can be closed remotely.
Digital energy management system founded on these data is the decision basis for energy conservation and emission reduction.
Mode of data transmission
Two layers data transmission:
* Radio frequency communication: the fixed data transmission between meters and concentrator via Wireless Ad hoc network, available for 7 layers data transmission.
* M-bus cable communication: the fixed data transmission between meters and concentrator via M-BUS port. The protocol is DL/T645 or CJ/T188.
The data transmission between concentrator and data center via GPRS or Ethernet.
M-bus is the short for Meter-bus, a bus architecture special for public utilities of meters. With embedded m-bus module, data can be transmitted between meters and concentrator via two parallel wires cable.
1 High speed communication rate, long distance stable communication
2 Available for serial interface, star connection, cross connection
3 Non-polar two parallel wires cable easy for field installation
4 Anti-interference, insulating devices by constant current electric current loop communication
The Ad-Hoc Network based on which meters communicating with concentrator or with other meters is the most important feature and technology of this system. In this Ad-Hoc Network, wireless water meter is available for 8 layers route data transferring. With the possibility of meter data being sent from first meter step by step to the eighth meter, this technology expands the communication distance and strengthen the data transmission, makes the functions of automatic meter reading & controlling, automatic data upload, router management be implemented quickly and in high success rate by wireless concentrator without any manual work, even meters installed in complicated surroundings.
