【正文】 基于單片機的語音警報系統(tǒng)設(shè)計 摘 要： 本文介紹了住宅智能化中的防盜防火報警系統(tǒng)。智能化住宅防盜防火報警系統(tǒng)集防盜防火功能于一體，可實現(xiàn)自動檢測與自動電話撥號報警。自動檢測是指由紅外探測與微波探測器構(gòu)成的雙鑒探測器實現(xiàn)盜情檢測，同時由溫度探測器、光電感煙探測器和一氧化碳探測器集為一體的復合式火災探測器完成火情檢測。多傳感器的應用實現(xiàn)了低誤報率，增強了系統(tǒng)可靠性。自動電話撥號報警是指通過電話網(wǎng)絡(luò)自動向相關(guān)部門發(fā)出語音求救信號。當防盜、防火探測器檢測到險情的時候，向單片機發(fā)出中斷申請，再由單片機控制電話接口電路 ，實現(xiàn)模擬摘機，根據(jù)險情類別，自動撥打相關(guān)部門的電話號碼。 關(guān)鍵詞： 防盜，防火，自動撥號，語音報警 Abstract： A kind of intelligent alarm system for residential area is introduced. It includes the functions of theftproof and frreproo， performing automatic detection and automatic dial. Pyroelectric infrared sensor and Microwave sensor bined are used for theftproof so as torealize automatic detection. Temperature sensor. make the least false alar Photoelectric smoke sensor and CO sensor are integrated to a pound detector for fireproof. Multisensors m and enhance the reliability of system. Automatic dial means that it can send help voice through public telephone switch work to the bureau. When the sensor of fireproofing or burglarproof detects any off normal signal, an interrupt request is sent to the MCU. Next the MCU control the interface module of telephone to acplish off hook. According the kind of dangerous, the dialing module will automatically dial the right phone number .
