【Abstract】 As the operating parameters of 10 kV power system for railway vary quickly and the transmission and processing of massive data are much tough,the SCADA system with synchronous real-time data transmission is developed.The remote transmission of operational data and recorded data is analyzed and the processing of massive real-time data is designed.The asynchronous transmission of real-time data is proposed based on the publisher/subscriber principle and two-level caching mechanism is established to guarantee information integrity and avoid important information loss.The developed system operates stably and reliably,with better real-time performance.更多还原
