Optimization of a SCADA system based on client/serve mode

In this paper a Supervisory Control and Data Acquisition (SCADA) system based on the client/server model is presented. It is developed for the traction power administration system of Beijing-Zhengzhou electrified railway. The system hardware configuration and software functions are introduced first. Then the optimization of this SCADA system is discussed. The motivation of optimization is to diminish the affect of network bottleneck and allocate the server´s load more reasonably. The optimization can be done from four aspects: (1) choosing an operating system, (2) data structure definition, (3) network administration, and (4) the server´s load reduction. After the optimization, this SCADA system performs better than before in many fields
