22、t;jor aci ments fist nn-l智能光電感煙探測器JTY-GD-G3 (GST2.908.488)作者：劉增宏、原理框圖二、工作原理:光電感煙探測器是利用光的反射原理來檢測空氣中煙霧的濃度,對火災(zāi)作出反應(yīng)。探測器主迷宮1、迷宮2、發(fā)射管、接收管及線路板組成。在監(jiān)控狀態(tài)下，發(fā)射管發(fā)出的紅外光，只有少部分經(jīng)迷宮反射后被接收管吸收。當(dāng)有煙霧進(jìn)入探測區(qū)時,由于煙霧粒子的反射,接收管吸收的光通量將增加,接收元件進(jìn)入接收管的光信號，被接收管轉(zhuǎn)換成電信號，并經(jīng)放大電路放大，當(dāng)煙霧達(dá)到一定濃度時, 收到的光信號達(dá)到預(yù)定的閾值，輸出報警信、電路組成:光電探測器以PIC16C72A、光電發(fā)射管及

23、接收管組成的電路為核心，對煙霧進(jìn)行監(jiān)測報警。3.1二極性變換電路：由VD1、VD2、VD9、VD10 組成。3.2輸入電路:VD6、VT2、R2、R3、C9 等組成。3.3回碼電路:C18、VT1、R21 組成。3.4穩(wěn)壓電路:VD5、R7、C12、D3組成穩(wěn)壓電路，為探測器提供電源。3.5光電信號發(fā)射電路:VT3、VT4、R22、VD3及外圍組件組成。3. 6光電信號接收電路:C1、C2、VD4組成光電接收電路。3.7信號放大電路：由N1及周圍元件組成。四、維修流程4.1 總線短路故障:重點檢查二極管 VD1、VD2、VD9、VD10是否擊穿對地短路，總線端子與地短接。4.2 燒地址失敗或點

24、名不正常:應(yīng)首先檢查16C72A第1腳電壓是否正確。如無電壓，依次檢查VD1、VD2、VD9、VD10、VD5是否損壞，D3是否損壞，C12、C7、C16、C6是否損壞，16C72A 第1、2、57、20腳是否對地?fù)?穿1;如電壓低于正常值，可能由于電容等元件損壞，將電壓拉低。應(yīng)依次檢查C12、C7、C16、C6、D3是否損壞；如電壓正常，應(yīng)測量 9、10腳波形是否正確，如無波形，檢查晶振和C10、C11 ,如有波形檢查24C02 ,測量16C73B的22腳，若3次回碼為窄脈寬，則 24C02壞。4.3 24LC02 故障：用電子編碼器的對講功能來測試24LC02 ,同時用示波器監(jiān)測 PIC1

25、6C73B第22腳回碼波形，若連續(xù)三次回碼均為窄脈寬說明24LC02已損壞。4.4 對講故障：首先檢查發(fā)射管處測試點是否有發(fā)射波形，其幅值是否達(dá)到2.1V;再檢查運(yùn)放LM324的輸出幅值是否達(dá)100 mV,在對講功能下，幅度是否達(dá) 4.5V;若不滿足上述要求請檢查發(fā)射、接收電路是否正常。4.5 誤報火警：首先打開迷宮，檢查迷宮內(nèi)是否有顆粒狀或絲狀灰塵，如有則清除；再檢查16C72A的3腳波形是否飽和LM324及LM324外圍器件； 若以上各項均正常，用電子編碼編寫器檢查其靈敏度設(shè)定是否 為正常值。4.6 不報：檢查16C7 2A的3腳波形是否正常，正常，檢查 16C72A、24C02 ;不正常

26、，檢查 LM324 ;檢查接受電路、發(fā)射電路波形，檢查 16C72A的12腳波形； 指示燈不亮檢查指示燈是否損壞。4.7 燈常亮或不亮：R8是否損壞。5.2集成電路16C73B的3腳依次中查16C72A是否損壞，發(fā)光二極管 五、探測器主要測試點波形5.1發(fā)射管正極1.7V0.5ms5.3集成電路16C72A的12腳5.2V2.5mV130ms anda on.Trui g ni-,“ful ply t roe of -hn nagemet, -pr o-d pro-smaagemet.，hs year 1 owe hea de eakage "ie p mj" 29 of
