Through the realization of the GPS receiving module and GPRS communication module in the vehicle- carrying module, therealization of interface communication between the GPRS communication module and USB module in the control center.

Combining with China’s national conditions, The paper study and design a set of GPRS network energy meter based on ADE7758 .

Implementation of data communication action and function of LF level 2 computer system;

Realization of Data Communication between PC and PLC in Fault Online Monitor System under DELPHI Platform;

A design for data communication of multiple-rate timeshare Watt-hour meter;

Communication Between GEPAC71 and VersaMax_I/O;

According to the characteristics of wide coverage, large number of users and complicated situation of power consuming in Shengli Oil Field, a set of remote metering systems is set up with the help of data communication service provided by the mobile communications company and GPRS data collecting terminal station.

In order to accomplish the control on-line in systems, it s very important for the reliable data communication between computer and subsidiary systems, It s introduced that way of network control system with ARLNC429 and CAN bus in the text.
