串行通信在远程监控系统中的应用

由于微软类库中没有对串口进行操作的类,为利用VisualC 开发与硬件接口有关的串行通信程序带来了一定的不便和困难.基于面向对象的编程思想,对Win API函数库中有关串口编程的函数进行了类的封装,提出了串行通信程序设计的一般方法,给出了远程监控系统的软件实现过程.实际运行表明,该系统具有较强的稳定性和可扩展性,适用于监控对人体有害的工作环境.

The Serial Communication Application in Remote Monitoring System

Microsoft Foundation Class has not a class that can operate serial port, So it is inconvenient and difficult to develop serial communication program about interface of hardware by Visual C . This paper encapsulates some Application Programming Interface functions about serial port program by a class and tells general method of serial communication program designing. This paper also gives process of realizing remote monitoring and controlling system. The field test indicates that the system has strong stability and expansibility. The system, especially, is applicable to monitor and control the working environment that is harmful to human.
