| Abstract: | The design and implementation of intelligent alarm system based on dual-tone multi- frequency （DTMF） are introduced. The system structure and the hardware of the system are presented, as well as the algorithm. The hardware design includes infrared radio circuit design, DTMF circuit design and AT89C2051 microcontroller circuit design. The software design includes preventing lightning algorithm design, short circuit alarm design and open circuit alarm design. The experiment result proves that the system has good real-time performance and stability, and has good alarm effect. |
