This research proposes a CENIS (Circuit Equipment Network Information System) for circuit equipment repair service craftsmen. The system is used for improving the efficiency and reducing the repair time. This system is able to upgrade the maintain and update information of resource in the International Transmission Maintenance Center (ITMC) from manual to computerized and automatic. The main functions include data inquires, data updates and the display of repair-time over alarm via web browser. In addition, it provides the following function Password checking, administration, statistic and operation tables. To make sure that the system operates efficiently and quickly, we developed this system by using Web Application technology, which provides an integration of quick computer data processing and resource sharing. In this paper, we first introduce the system functions of CENIS. Then, we describe the system hardware architecture and software configuration.
