摘　　要：设计了一种基于GPRS短信模块的远程控制系统,借助移动通信网的GPRS网络,采用短信息模式进行通信,从而达到对一些野外或异地终端进行控制。该系统由上、下位机组成,上位机又由GPRS短信模块和PC机组成,两者之间通过串口使用AT指令进行通信。上位机用户界面采用C++Builder软件设计。下位机由GPRS短信模块和51单片机终端系统组成。上位机可以随时读取下位机的工作参数,根据当前参数,用户可以对系统的工作状态进行控制。该方案进一步促进了工业控制系统的智能化和信息化。A remote control system based on the GPRS short-message module is designed, thus with the aid of GPRS network for mobile communication and by short-message communication, to achieve the control on some open-country or strange-land terminals. This system is composed of upper- and lower-position machines. The upper-position machine is composed of GPRS short-message module and PC, the communication between the module and PC is realized through serial port and AT instruction. The user interface of upper-position machine is designed with C＋＋ Builder software, while the lower-position machine consists of GPRS short message module and 51 monolithic integrated circuit terminal system. The upper-position machine may read operation parameters of the lower- position machine. Based on the current parameter, the user may implement control on the actual operation status of the system. This scheme could further promote intellectualization and informationization of the industrial control system.
