RESEARCHES ON THE INTELLECTUALIZED TESTING SYSTEM OF THE SECONDARY ELECTRON EMISSION YIELD OF SPACE MATERIALS BASE ON KINGVIEW 6.52 AND PLC

This paper describes an intellectualized testing system of the secondary electron emission yield of space materials by integrating the technology of electronic control and communication base on Kingview 6.52 and PLC.The system achieves the multithreading intellectualized control of vacuum obtaining,pulse modulation of electron gun and on-off of all electrical sources.The application of Kingview 6.52 makes the design of system more convenient and improves the control quality.The communication with PLC through serial interface improves the ability of data collection and real-time disposing of the industry personal computer.
