摘要
本文介绍了实现基于电话线的嵌入式远程控制单元的设计方案。在文中主要介绍了该设计的硬件电路和软件设计流程。嵌入式远程控制器的MCU采用AT89C51单片机,由MT8870实现电话按键的DTMF信号的解码,用可多次录放的语音芯片ISD1110实现语音提示。通过操作电话按键实现对远程被控对象的控制。
The design of Embedded long distance controller based on telephone net in this paper. Mainly introduced the hardware constitute and the process of softwares in the paper. The MCU of the controller is made of single chip processor of AT89C51. The device of MT8870 is used to decode the DTMF signal of the telephone key. The voice device of ISD1110 is used to play the voice hint.
