摘要
以AB DF1串口控制协议为例,说明了利用CDMA/GPRS DTU传输串口数据和组建无线远程控制系统(SCADA)的基本方法。对系统组建所涉及的软硬件环境进行了介绍,并详细描述了DF1控制协议的分析过程和将其与DTU开发包集成以实现新的通讯驱动的原理。通过此类原理,我们可以实现在统一的软件构架下,通过加载所需的通讯驱动,与包含不同用户设备的RTU进行通讯,而这样的RTU,均是采用DTU为其通讯手段。
This paper goes into the basics of creating a driver that integrates the AB DF1 protocol and CDMA/GPRS wireless communications,the integrated drivers can transmitte the serial communication data through the IP packets that transmitted by a CDMA/GPRS DTU(Data Terminal Unit).Based on a uniform software construction,we can design a SCADA system that works with RTUs and the RTU is used in various different serial communications protocol or any others filed protocol.All the wireless communications will be based on DTUs.
