摘 要
文章系統(tǒng)地介紹基于DTMF遠(yuǎn)程控制系統(tǒng)的組成、設(shè)計(jì)方案、電路原理、程序設(shè)計(jì)及產(chǎn)品的研發(fā)過程。DTMF遠(yuǎn)程控制系統(tǒng)是以AT89C51單片機(jī)作為控制核心，MT8870為DTMF信號(hào)的接收電路及其它的外圍電路，在系統(tǒng)程序的控制下實(shí)現(xiàn)功能。該系統(tǒng)由振鈴信號(hào)檢測(cè)、摘、掛機(jī)控制、雙音頻解碼、語音提示及電器控制五大電路部分組成。它適用于家庭、商店等無人的場(chǎng)所、還可以用于工業(yè)控制現(xiàn)場(chǎng)。以電話作為媒介， 通過電話線完成對(duì)設(shè)備的遠(yuǎn)程操作。
關(guān)鍵詞：電話遙控、雙音頻解碼、單片機(jī)
Abstract：
Using The AT89C51 Single Chip Processor and the MT8870 Decoder, which is specially used for decoding multiple dual channel audio frequency signals , as core components, the control system of the intelligent telephone can remotely control the electric appliances through the PSTN (Public Switched Telephone Network). This article introduced the control system’s constitution, it’s working principle, and the program designed idea. The detail specification for several main function circuits which is used for telephone ring detecting, picking up a call simulating, dual channel audio frequency signals decoding, voice suggestion, and electric appliances controlling were provided. This control system can be used in home, stores, and offices.
Keywords: Remote controlling through telephone, dual channel audio frequency coded and decoded, controlling under a Single Chip Processor
