As shown in Figure 4, the present invention surveys by 11 pairs of combustion gas of combustion gas detecting alarm, and the signal that detects is passed to controller 6; Controller 6 is controlled exhaust fan 1, solenoid valve 2 and telephone automatic dialing device 4 automatically according to the detectable signal of combustion gas detecting alarm 11.
As shown in Figure 3, link to each other with 1 one input ends of door and voltage stabilizing sheet are anodal, make this input end remain high level, another input end is the high level pulse signal input part, unilateral diode D1 and and door 1 high level signal input end between be connected to resistance R 5, R6 and capacitor C 4.Capacitor C 4 positive poles are connected on the signal input line after the resistance R 5, and negative pole links to each other with the negative pole of voltage stabilizing sheet.Resistance R 6 one ends are connected on the signal input line behind the R5 equally, and the other end links to each other with voltage stabilizing sheet negative pole, make resistance R 5, R6 and capacitor C 4 with the signal input part of door 1 on form a RC circuit, link to each other with triode T1 base stage through resistance R 1 back with door 1 output terminal.Its course of work is as follows: (a) when not having the high level signal input, with one of 1 two input end of door be high level, another is a low level, its output terminal output low level, triode T1 is in cut-off state, relay J coil and power supply disconnect does not have electric current to pass through, and exhaust fan is in closed condition.(b) when the high level pulse signal is imported, signal arrives with door 1 signal input part through unilateral diode D1, resistance R 5 backs and also becomes the output high level by output low level, triode T1 is become by cut-off state and full closes state, and engage relay J coil power starts exhaust fan.(c) behind the high level pulse blackout, return to low level with door 1 signal input part by high level, its output terminal also reverts to output low level.The extensive cut-off state that obtains of triode T1 disconnects the relay J coil power, closes exhaust fan, thereby has realized that the combustion gas detecting alarm reports to the police for the 1st time, and controller starts exhaust fan and the function of automatic delay function exhaust fan behind all clear.
Link to each other with the voltage stabilizing sheet is anodal equally with 2 one input ends of door, make this input end keep high level, another input end is the high level signal input end, and its output terminal links to each other with triode T2 base stage through resistance R 2 backs.And with door 2 outlet lines on other be connected to three paths: one through linking to each other with high level signal incoming line behind the unilateral diode D2 behind unilateral diode D3 and the normally closed switch K1; Another with link to each other with 3 one input ends of door; Article three, link to each other with voltage stabilizing sheet negative pole through behind resistance R 3 and the light emitting diode T3.Its course of work is as follows: (a) as high level signal through unilateral diode D2 when reaching with door 2 signal input parts, its output terminal becomes the output high level by output low level, triode T2 becomes the full state that closes by cut-off state.When connecting power of electromagnetic valve, when closing solenoid valve, cutting off burning line and continue to leak to stop combustion gas.Make with door 3 with the high level of door 2 output terminals output simultaneously and become high level by low level with the input end that links to each other with door 2 output terminals; With the high level of door 2 output make light emitting diode T3 have forward current by and send ruddiness, indication solenoid valve this moment cuts out; Get back to high level signal input end with door 2 after through unilateral diode D3 and normally closed switch K1 with the high level of door 2 output, form high level output self-locking.(b) after high level signal disappears.Because with door 2 high level output self-locking, therefore, its output terminal is still exported high level under the situation of not release.When the state of triode T2, solenoid valve, light emitting diode T3 is constant, press normally closed switch K1 after, become low level with its output terminal of door 2 high level output release by high level, triode T2 returns to cut-off state.Disconnect power of electromagnetic valve and open solenoid valve, light emitting diode T3 does not have forward current to pass through, no longer send ruddiness, make with door 3 and revert to low level by high level with the input end that links to each other with door 2 output terminals, thereby realized that the combustion gas detecting alarm still closes at all clear rear electromagnetic valve, and the ruddiness that is sent by light emitting diode T3 is as indication.After pressing K switch 1, solenoid valve is opened, the function that light emitting diode T3 extinguishes.
Binary counter output terminal Q1 through behind the unilateral diode D6 with link to each other with door 3 another input ends.Linking to each other with triode T1 base stage with resistance R 1 back through unilateral diode D5 with door 3 output terminals, and with door 3 outlet lines on (front of unilateral diode D5) other two paths and extension of being connected to, promptly path is for through getting back to the input end that links to each other with door 3 sum counter output terminal Q1 behind the unilateral diode D4; Another is to link to each other with the negative pole of voltage stabilizing sheet through behind resistance R 4 and the light emitting diode T4.Telephone automatic dialing device socket one end and join with extension on door 3 outlet lines, the other end and voltage stabilizing sheet negative pole join.Its course of work is as follows: (a) after the 1st high level signal arrived the counter input end through unilateral diode D7, counter began counting.At this moment, counter output Q0 exports high level, Q1, Q2, Q3 output low level.With one of 3 two input end of door be high level, another is a low level, its output terminal output low level, light emitting diode T4 does not have forward current to flow through, and can not send gold-tinted.The potential difference (PD) at telephone automatic dialing device socket two ends is poor less than the minimum initiate potential of 1.5V, and the telephone automatic dialing device can not start, and predefined number is not carried out telephone remote and reports to the police.Triode T1 also is in cut-off state, can the engage relay coil power, start exhaust fan.(b) after the 2nd high level signal arrives the counter input end, counter output Q0, Q2, Q3 output low level, and Q1 output high level.With 3 two input ends of door all this moment all be high level, its output terminal also becomes high level by low level.Make triode T1 be become by cut-off state with the high level of door 3 output terminals output and fullly close state, the engage relay coil power starts exhaust fan.The potential difference (PD) that telephone automatic dialing device socket two ends form is poor greater than the minimum initiate potential of 1.5V, starts the telephone automatic dialing device predefined number is carried out phone and door 3 remote alarmss.Simultaneously with the high level of door 3 outputs through unilateral diode D4 after, got back to the input end high level that links to each other with door 3 sum counter output terminal Q1 again, behind unilateral diode D4, got back to the input end that links to each other with door 3 counter output Q1 again, final formation exported the high level self-locking.Make light emitting diode T4 have forward current to flow through with door 3 output high level, gold-tinted indication telephone automatic dialing device this moment that sends starts, and air draft has also started and self-locking automatically.(c) after the 2nd high level signal disappeared, the counter output output level is constant, and was also constant with door 3 output terminal output levels.So, the state of triode T1, exhaust fan, telephone automatic dialing device and light emitting diode remains unchanged, thereby when having realized that this device (solenoid valve still is in the not zero clearing of closed condition, counter on the burning line) combustion gas detecting alarm under situation about not resetting detects indoor leakage gas concentration above the warning of warning concentration for the 2nd time, controller can start exhaust fan and self-locking once more automatically.Also can start the telephone automatic dialing device simultaneously and carry out the telephone remote warning, remind the user that the dangerous situation of gas leakage takes place by telephone call according to predefined number, and the function that need in time handle.
Unilateral diode effect of the present invention is to allow the high level pulse signal is unidirectional to be passed through, and avoids influencing each other between each control section signal.Indication uses light emitting diode 16 as the indicator signal under exhaust fan 1, solenoid valve 2 and telephone automatic dialing device 3 corresponding states.The effect of capacitor C 1, C2, C3 is that remaining alternating current guarantees that controller 6 is normal, reliably work to the influence of controller 6 each element and high level pulse signal behind the elimination rectifying and voltage-stabilizing.
Counter system zero end can link to each other with the positive and negative electrode of voltage stabilizing sheet 15 respectively by two-way switch K2.When rolling counters forward time system zero end and voltage stabilizing sheet during 15 anodal linking to each other, press the zero end of K switch 2 back systems and voltage stabilizing sheet 15 negative poles mutually, counter O reset, its output terminal Q0, Q1, Q2, Q3 have output low level.Reset switch is formed by normally closed switch K1 and two-way switch K2 common combination, and after pressing reset switch, counter will be forced system zero, and basic output terminal all is a low level; Normally closed switch K1 disconnects, and with door 2 high level output release, output terminal becomes low level by high level.At this moment, triode T2 returns to cut-off state, disconnects solenoid valve 2 power supply opening solenoid valves, and light emitting diode T3 extinguishes.Be low level with door 3 with the input end that links to each other with door 2 output terminals simultaneously, make to become low level by high level high level output release with door 3 output terminals.And then make that triode T1 is extensive must be to cut-off state, disconnect the relay J coil power and close exhaust fan 1; The potential difference (PD) at telephone automatic dialing device 4 socket two ends is poor less than the minimum initiate potential of 1.5V; Light emitting diode T4 extinguishes.After decontroling reset switch, normally closed switch K1 closure; Counter system zero end recovers high level, can restart counting again.
