一种新型程控交流源上位机软件设计

摘要

A design method of host computer software for a programmable inverter power on Delphi is discussed. This software communicates with more programmable powers by GPIB or RS232 serial interface, which can realize some functions such as communication type select, output mode select, working parameter reading, data saving and SCPI testing etc. Some key technologies as communication protocol, multi-threads and serial interface driver are introduced in detail. Finally, some procedure examples are presented.%介绍了一种在Delphi环境下实现程控交流源上位机监控软件的设计方法.该软件通过GPIB接口或RS232串口与多台程控电源通信,实现通信类型和输出方式选择、电参数回读、数据保存、SCPI命令测试等功能.详细介绍了通信协议、串口驱动、多线程等关键技术,并给出了部分编程示例.
