摘要
长距离通讯对分布式控制系统实现远程控制具有重要意义。文章介绍了一种长距离通讯方式及在具体装置上的设计过程和实际应用，并对软、硬件配置进行了说明。实验证明该系统可以在ＰＣ机上直接控制有效范围１２００ｍ内的对象，具有控制准确、传输距离远、误差小、速度快、易于操作、控制对象切换方便、主站通讯界面友好等特点。
Distant communication is essential to implementation of remote communication mod e and its
design process and practical application in the device is described.Th e hardware/software
configurations are also stated. The practice proves that thi s system can directly control the object
within the effective range of 1200m on the personal computer,which features with accurate control,
distant transmission, less error,fast speed, easy operation,easy changeover of controlled objects
and communication interface oriented for master station.
