摘　　要：目前,远程自动控制中所采用的遥控方式主要有有线遥控和无线电射频遥控,由于受到地域条件和无线电频率资源的限制,有线遥控和无线电射频遥控往往不是最经济、最有效的远程控制方式。该系统以公众电话网为平台,以单片机AT89C51为控制手段,通过音频传输与控制,实现远程自动供水。包括发送和接收两个子系统,研究内容涉及数据采集、控制信号生成、自动拨号、振铃信号检测、控制执行等。Currently, the main control ways which the long range automatic remote control adopted inelude wired remote control and radio remote control. Subject to the restriction of region and the radio frequency resources, wired remote control and radio remote control usually are not the most economic and the most effitient control way. The project uses PSTN （Public Switched Telephone Network） as its base and uses single chip microcomputer as control means, by audio signal transmitting and controlling, realizes long distance automatic water supply. The system includes a sending subsystem and a receiving subsystem, the research topics involve the data collection, the generation of control signal, the automatic dialing, the detecting of the tinging signal and its checking and the carrying out of control etc.
