By analyzing the working conditions and functions of the intelligent controller, a smart home control solution is proposed on this basis. The smart home control uses mobile phones or landlines to remotely control household appliances through the public telephone network. According to functional requirements, starting from hardware design, the ARM7 series microcontroller LPC2132 is selected as the core microprocessor, MT8870 is used as the dual-tone multi-frequency receiver, and the voice recording and playback chip ISD4004 and the execution relay, as well as the corresponding high-efficiency switching power supply constitute the entire hardware circuit. Then the software is analyzed, the overall software flow chart is given, and the design of the intelligent controller system is completed.
