摘要
设计并实现了一种以单片机AT89C51和双音多频解码集成电路MT8870为核心,基于PSTN(公共交换电话网)的家用电器远程多路智能控制器。此设备具有振铃检测、密码校验和指令译码及执行等多项功能,提供多路开头控制接口和数字量控制接口,可以根据用户远程指令来执行相应控制。经过实际测试,该设备能正常工作,实现了设计中的所有功能,具有一定的实用价值。
Design and realize one AT89C51 and DTMF decoding integrated circuit MT8870 for the core frequently with one-chip computer, long-range intellectual controller of several ways of household appliances which on the basis of PSTN. This equipment has several functions, such as shakes bell measuring , password check-up and order decipher and operate automatically, provide several roads switch control of connection and numerals control of connection, can carry out the corresponding control according to the customers remote instruction. Tested actually, this equipment can work normally, has realized all functions in the design, have certain practical value.
