AMR system is applied to read and collect power consumption information from meters by host station through communication tech. It is a long distance from the host/database server to concentrators to transfer data, so using GPRS, CDMA, FDDI, etc; A short distance from concentrators to meters we use PLC, RS485. AMR is also support switching on/off the meters remotely.

 

Power companies are now adopting meter reading and management system to replace the existing residential manual meter reading system, which is able to save the cost of human resources, cut down the meter reading cost, meanwhile realize real time meter reading efficiency and improve successful reading rate; besides, automatic computer meter reading could decrease the manual reading error rate; to prevent fraud from dishonesty manual meter reading operator, cut down the lost of power companies, to monitor residents power consumption status, timely alarming will be sent once discovered abnormal event; At the same time, able to read and collect general zone meter, line loss can be calculated and analyzed.

 

Developed by Java language, the system can be installed in a variety of mainstream operating systems. Using three-level structure (users end / application server / database server) with J2EE as system framework, it also support Oracle, Sybase, SQL database. Core business processing logic as the form of Middleware is deployed in one or several J2EE application servers. System designed to take full account of the current wide distribution of power company customers, more access points, as well as large differences in scale of electricity supply, it has good opening, scalability, flexibility, high reliability and so on. Adopting a large number of advanced computer technology, communications technology, it can meet the need of the power company for AMR management under new environment very well.
