Optimization of Interface Data Refresh Method in Power Dispatch SCADA System
摘要
Abstract
In view of the problems of server over-load,data inconsistency and data update loss in the large-scale interface data refresh by current data refresh methods,an optimized interface data refresh method is proposed.By using event triggered subscribe/push mechanism,the link sharing technology and the screen synchronized push technology,the optimized method is able to reduce the server load and improve data consistency.Comparison tests show that the optimized interface data refresh method is superior to the CPU usage,memory usage,and the data update loss rate.Practice has proved that the optimal method is more suitable for large-scale interface data refresh,thus better meeting the requirements of a new generation of electric power supervisory control and data acquisition(SCADA) system interface data refresh.关键词
