Realization Of Data Acquisition System In Power System Based On Wide Area Measurements

The paper is based on the measure technic in the wide area measures of power system atpresent. It proposes and realizes data acquisition system based on ARM. Beginning with thecharacteristic and constitution of embedded system and the software and hardware frame ofdata acquisition system, it analyzes the principle of software and hardware of the dataacquisition system which uses the embedded microprocessor S3C44B0X, describes thecomposition structure and operation principle of modules as GPS clock, data entry andacquisition, data transmission, etc., and introduces the transplantation of the operating systemand setting-up of TCP/IP network platform in detail. Finally the equipment driver andapplication programs are expounded and the test result is provided.
