| 摘 要： | 在Ｗｉｎｄｏｗｓ’９５平台下，利用ＶｉｓｕａｌＢａｓｉｃ５．０中提供的ＭＳＣｏｍｍ通信控件，开发了ＩＮＦＩ－９０与ＰＣ机接口的应用程序。该程序采用了ＩＮＦＩ－９０以及标准的串口通信协议。在通信过程中采用事件驱动方式，保证了通信的实时性和程序的多任务性，并且合理地考虑了发送和接收的时序，实现了多点采样。该软件的开发，也为Ｗｉｎｄｏｗｓ平台下实现其它分散控制系统与ＰＣ机之间的通信，提供了一种解决的思路。

| Abstract: | This paper introduces an applied program for the interface between INFI-90 and a personal computer(PC). The program is developed by means of MSComm communication control provided by VB5.0 under Windows'95. The program adopts communication protocol of INFI-90 and standard serial port. It assures Real-timeand multi-task properties of communication by adopting event drive mode in communication process. It realizesmulti-point sampling after taking account of the time sequence of data sending and receiving. The software provides a way for realizing communication between other DC.S and PC under Windows' 95. |
