摘要
本文介绍一种利用调制解调器进行远程测控系统通信的方案。远端由单片机通过RS232串行口控制调制解调器,本地主机由系统机和调制解调器组组成。利用电话线进行全双工数据通信,传输距离长,传输速度较快,应用简便,既具备单片机多系统成本低,实时性强,操作简单的特点,又拥有系统机适于大量数据处理,用户界面友好,使用维护方便的优点。
This article introduces a method of performing remote communication by using MODEM. In the remote, the microcontroller through RS232 serial interface controls MODEM, and the local main computer is made up of system computer and MODEM. Performing data communication by using telephone wire conveys long distance and high speed.The method has not only microcontroller' s characters of muti-system, strong same time and single operation, but also company with system computer' s advantages of being able to manage a great deal of data, good user' s interface and simple keep.
