利用通讯线路进行远程数据传输与控制

Remote data transfer and control by use of lines of communication

介绍了一种利用通讯线路（电话线）进行远程数据传输与控制的方案．该方案利用单片微机作为信号采集与控制的核心，采用电话机的拔号原理进行数据传输．该方案传输数据稳定可靠，占用线路时间短，而且不受距离限制，较适于远程遥控系统或集中控制等场所作为数据传输与控制，还可用于居民区作为防盗，防止煤气泄漏等的智能报警系统等．

This paper introduces the design of remote data transfer and control by use of lines ofcommunication(telephone lines). The core of datacollecting and control is a singlechip. By use of thisdesign, the data transfer is stable, the transacting time is short, and there isn't the limit of distance.There fore, the design is fit to data transfer and control in the field of the remote controlsystem, centralizing control, and the alarming system in the field of guarding against theft inresidential area and guarding against leakage of gas.
