Description

A kind of wireless with have the line traffic control fire-fighting to cut circuit by force

Technical field

The utility model relates to the fire-fighting circuit field, particularly relate to a kind of wireless with have the line traffic control fire-fighting to cut circuit by force.

Background technology

It is very important interlock that fire-fighting is cut by force in the fire alarm interlock, and when breaking out of fire, fire alarm system sends to the distribution box circuit breaker and cuts signal by force, cuts off main circuit power, guarantees fire fighter's safety and avoids fire spread.But traditional device has only wire transmission mode, just in case wired wire rod is had no progeny by baked wheaten cake, can not realize long-range forced cutting function.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of wireless with have the line traffic control fire-fighting to cut circuit by force.

The technical scheme that the utility model adopted is such: a kind of wireless with have the line traffic control fire-fighting to cut circuit by force, comprise radio transmitter, wireless receiving circuit, wired external trigger circuit, single chip machine controlling circuit, described radio transmitter is launched frequency electromagnetic waves to wireless receiving circuit, the output signal of this frequency electromagnetic waves and wired external trigger circuit is sent to single chip machine controlling circuit, is controlled warning circuit and is driven electronic by single chip machine controlling circuit output.

Described radio transmitter and wireless receiving circuit adopt FDD-5 transmitter module and JDD-5 receiver module respectively.

Described wired external trigger circuit connects the photoelectricity coupling circuit by trigger switch output and forms.

By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: this circuit adopts wired input signal circuits for triggering and wireless transceiver circuit, cuts off drive signal by Single-chip Controlling output, makes circuit breaker cut off main circuit power, can strengthen reliability, guarantee fire fighter's safety.

Embodiment

Further specify the utility model below in conjunction with the drawings and specific embodiments.

As shown in Figure 1 and Figure 2, a kind of wireless with have the line traffic control fire-fighting to cut circuit by force, comprise radio transmitter 1, wireless receiving circuit 2, wired external trigger circuit 3, single chip machine controlling circuit 4, the frequency electromagnetic waves of 1 pair of wireless receiving circuit of described radio transmitter, 2 emissions, the output signal of this frequency electromagnetic waves and wired external trigger circuit 3 is sent to single chip machine controlling circuit 4, is controlled warning circuits 41 and is driven electronic 42 by single chip machine controlling circuit 4 outputs.

Described radio transmitter 1 is made up of K switch 1, FDD-5 transmitter module U2, described wireless receiving circuit 2 is made up of JDD-5 receiver module U3, loud speaker Y, resistance 1R3, LED 1, when K switch 1 closure, FDD-5 transmitter module U2 pin is low-potential state, the triggering signal input is arranged, and deliver to its 3rd pin CP modulation signal input end, the high-frequency signal of emission is modulated.FDD-5 transmitter module U2 output connects antenna and promptly JDD-5 receiver module U3 is launched modulated frequency electromagnetic waves, and expression needs long-range cut-out main circuit power.When JDD-5 receiver module U3 receives transmitting of FDD-5 transmitter module U2, the 4th pin CPA audio signal output end of JDD-5 receiver module U3 directly drives common electrical dynamic formula loud speaker Y sounding, its the 2nd pin data output end is exported high level simultaneously, make LED 1 get electroluminescence, expression receives the alarm signal of extension set.Simultaneously signal is input to the 4th pin of single-chip microcomputer IC1, the output of the 4th pin of single-chip microcomputer IC1 is high level state, make diode Q2 conducting from its 21st pin output high level through resistance 2R2 current limliting through the control of single-chip microcomputer IC1 internal processes, promote loud speaker BD and send the alarm sound that ticks.The 34th pin output high level of secondary route single-chip microcomputer IC1 makes triode Q1 enter conducting state through resistance 1R2 current limliting, the relay J adhesive, switch J1-1 is by transferring normally closed point normal battle to, promote contactor KM adhesive, promote breaker device dropout outage simultaneously, guarantee fire fighter's fire-fighting safety and avoid fire spread, realize the wireless receiving warning, the function of cutting main circuit power by force.

Described wired external trigger circuit 3 is by trigger switch K, resistance 1R1, photoelectricity coupling circuit U1, resistance 2R1 forms, when fire alarm system sends triggering signal, trigger switch K closure, photoelectricity coupling circuit U1 enters conducting state, its output signal sends to the 36th pin of single-chip microcomputer IC1, the 36th pin of single-chip microcomputer IC1 is low level state, after single-chip microcomputer IC1 internal arithmetic is judged, control through single-chip microcomputer IC1 internal processes, the first via makes triode Q2 conducting from the high level of the 21st pin output of single-chip microcomputer I C1 through resistance 2R2 current limliting, promotes loud speaker BD and sends the alarm sound that ticks.The 34th pin output high level of secondary route single-chip microcomputer IC1 makes triode Q1 enter conducting state through resistance 1R2 current limliting, the relay J adhesive, switch J1-1 promotes contactor KM adhesive by transferring normally closed point normal battle to, promote breaker device dropout outage simultaneously, guarantee personnel's fire-fighting safety.
