The Research Of The Automatic Meter Reading System Based On Wireless Communication

Along with the deep innovation on electric power system and pushing the project that one meter per door in using power through the town, making the workload of charging the Meter Reading manually increased rapidly, AMRS(Automatic Meter Reading System) is a kind of effective technical methods to figure out the issue which existed in the manually meter reading system. On the basis of the general analyzing on existing AMRS as well as the practically applied requirements, this text designed a set of meter reading system according to the wireless network.Data transmit between the concentrator and the collector in the form of wireless ad hoc networks. The wireless ad hoc networks have lots of characteristics such as having no centre, self-organizing and multi-skip route. Adopt the wireless ad hoc networks, be apart from concentrator farther node can communicate with the concentrator through other nodes' transitions. After the analyzing on the issue when building the wireless as hoc networks often faced and the routing arithmetic in common used, according to the requirements of this meter reading system, predigesting network structure, designed a routing arithmetic which is based on call-over, the request of that arithmetic to each node hardware is lower, and drew up the related network protocol.Data transmit through GPRS (General Packet Radio Service) network between concentrator and control centre. As the continuous development of GPRS, the application of GPRS will be more and more extensive. The GPRS has the baud rate high, on-line forever, overlay the region wide etc. advantage which is suitable to collect some data of region dispersion very much. This text carries on the research to the system of GPRS and the application provide, discussing several kinds net project based on GPRS and the method dealing with the line problem. Request to choose the GPRS set net project that connects to go into with the special line of APN according to the system function, and designed the related hardware and software systems.Remote meter reading system based on ad hoc networks and GPRS can not only leave out the trouble in wiring but also realize Wireless communication on large-scale by using tiny power wireless module, that system have on-line forever, inexpensive cost of equipments, simple maintenance, cheap charges, quickly connection, in keeping with date uncertain, the long-playing data delivers etc. advantage. Therefore, it is full of important social and economic values that carry out this meter reading system.
