The operation principle and the course of work of the present embodiment：

During normal condition, the light that light emitting diode D sends due to no barrier direct irradiation, photosensitive audion VT by In the reflection light for receiving Infrared, so resistivity reduces, equivalent resistance diminishes, and due to photosensitive audion VT and electricity The partial pressure relation of resistance R3, the voltage increase of the detection signal of the in-phase input end input of operational amplifier U1, higher than reversely input The voltage of the reference signal provided by resistance R2, resistance R4 partial pressures is provided, so operational amplifier U1 is operated in positive saturation region, and it is defeated Go out the light detection signal of positive supply voltage, i.e., the light detection signal for now exporting is high level

During generation fire, handss are extended and carry out on the downside of Fire Alarm Button device trigger action by person for help first, work as handss After the palm is extended on the downside of housing 4, the light that light emitting diode D sends will be reflected back after exposing to palm, then by photosensitive three Pole pipe VT is received, and due to receiving Infrared so resistivity increases, equivalent resistance becomes big to photosensitive audion VT, due to sense The partial pressure relation of optical transistor VT and resistance R3, the voltage drop of the detection signal of the in-phase input end input of operational amplifier U1 It is low, the voltage of the reference signal provided by resistance R2, resistance R4 partial pressures less than reverse input end, so operational amplifier U1 work In reverse saturation region, the light detection signal of inverting power supplies voltage is exported, i.e., the light detection signal for now exporting is low level.

When high level is changed into low level, 555 chips are touched the infrared detection signal received when 2 pins of 555 chips Send out and start working, electric capacity C1 is started to charge up, and the now output of 555 chips is changed into the high level of temporary stable state from the low level of stable state, That is 3 pins export the time-delay closing signal of high level, when the voltage at electric capacity C1 two ends is charged to more than 2/3VCC, 555 chips Recovered to stable state by temporary stable state, 3 pins export low level time-delay closing signal, additionally, slide rheostat RW2 is connect by adjusting The resistance for entering part can adjust the discharge and recharge time of electric capacity C1, it is achieved thereby that the regulation to the time-delay closing time.

When 3 pins of 555 chips export the time-delay closing signal of high level, audion VT1 begins to turn on, then normally opened Formula relay KM1 work closes switch KM1-1, while pre- open instruction unit 33 is in response to time-delay closing signalman now Make, audion VT2 conductings make then bulb L1 be powered and start to light, and then point out to be now pre- opening, can carry out down The unlatching operation of one step.

After into pre- opening, within the time of time-delay closing, i.e., before time-delay closing signal is changed into low level, Person for help presses double-point double-throw switch SB disconnects open instruction unit, while ZIGBEE wireless modules 32 are connected start working, Fire alarm wireless signal is sent to monitor terminal, ZIGBEE wireless modules 32 are prior art, and this utility model here is not Repeat.

At the same time, police instruction unit in parallel with ZIGBEE wireless modules 32 is started working, and operational amplifier U1 is opened Beginning work, Jing after the partial pressure of resistance R8 and resistance R10, the voltage of the in-phase input end of operational amplifier U1 is higher than inverting input Ground voltage, operational amplifier U1 outfan output high level, and due to output signal feed back to reversed-phase output to electricity Hold C3 to charge, when making anti-phase input terminal voltage be more than homophase input terminal voltage to electric capacity C3 chargings, operational amplifier U1 outputs are low The signal of level, hereafter electric capacity C3 start electric discharge and cause anti-phase input terminal voltage again below in-phase input end, computing then is put Big device U1 output high level, charging, discharge process constantly repeat, so as to export required square wave, i.e. outputting oscillation signal, after And bulb L2 receives flashing after oscillator signal, buzzer SP is spaced song simultaneously and reports to the police, so as to point out people fire alarm Success, and warning fire of occur herein to surrounding.
