【摘要】 EAST装置中调节ICRH天线阻抗的真空调谐电容必须实现远程控制。基于串口通信技术,采用上下住机的形式,以工控机为上位机、以西门子PLC为下位机实现了真空调谐电容的远程控制,其中上位机控制界面采用虚拟仪器开发软件LabVIEW实现,不仅实现了对电容的远程控制,而且得到了交互性良好的人机界面。更多还原

【Abstract】 We must realize the remote control function in the Impedance matching systems for EAST ICRH antenna because the distance between vacuum tuing capacitors and the operating room is about 100 meters. Based on serial port communication technology, we designed the remote control system using PC& PLC.Through the use of LabVIEW-a special software for Visual Instruments,we not only realized the initial remote control function but also gets a friendly interface for the operators.更多还原
