Family Intellectualized Control System

摘要

This paper introduces a Family Intellectualized Control System, together with the discussion on the system's Circuit and their functions. This system employs AT89C51 as the main control unit, DTMF (Dual Tone Multi-Frequency) chips MT8880 and electric wire modem chips ST7536. Dual Tone Multi-Frequency in the telephone is directly used to send control message, then DTMF signals are decoded which is translated by AT89C51. According to the relative control signal, Circuit is driven to conduct the operation. This system gets the family electrical appliances, security alarm sensor and the internet integrated. Meanwhile, intellectual control over family electrical appliances and automatic alarm is actualized.
