摘要
在研究图形化组态软件在数字式微机保护中的应用时,涉及到PC机与TMS320F2812芯片串口通过RS-232串口进行DSP与PC之间的异步通信技术的问题。在研究近程的异步串行通信软件以及通信协议的基础上,给出了实现异步通信的硬件接口电路和相应的软件程序。其中上位机采用C++Builder6.0程序语言进行设计,利用串行通信控件TComm,实现了上位机平台软件与微机保护硬件之间的数据传输。
While study on application of graphic configuration software in digital microprocessor based relay protection is carried out, serial communication between PC machine and TMS320F2812 chip through RS-232 serial port to realize asynchronous communication between them is involved. Based on study on short range asynchronous communication and communication protocol, hardware interface circuit and related software to realize asynchronous communication is presented. C＋＋Builder6.0 is used as the upper computer software to realize data transmission between platform software and relay protection hardware with serial communication component TComm.
