Description

The intelligent linkage controller is set out in 119 fire alarm fire-fightings

Technical field

The utility model relates to a kind of intelligent linkage controller of accelerating fire brigade fire alarm reaction velocity, and specifically, it is that the intelligent linkage controller is set out in a kind of 119 fire alarm fire-fightings, mainly is applicable to fire brigade.

Background technology

Fire brigade is being undertaken the important task of the line of putting out a fire, and all be ready 24 hours every days.Common 119 fire alarm command centres are after receiving fire alarm, want rapidly to send to the remote terminal computing machine of each fire brigade residence duty room and set out order by computer network, the remote terminal computing machine sends the alert prompt tone by audio amplifier when receiving this order; If be not equipped with the residence of remote terminal computing machine, command centre is then by the Advise By Wire duty room; The operator on duty will sound alarm bell rapidly after in a single day hearing the alert prompt tone of computing machine or receiving Fire telephone, carries article such as the communication apparatus, fire extinguishing prediction scheme and scene of a fire record then; And the fire-fighting soldier after hearing alarm bell in a short period of time (within one minute) set out rapidly.The existing problem of this process is: the one, and order is set out in fire alarm can not start alarm bell automatically, incurs loss through delay the time that alarm bell is sounded easily; The 2nd, if set out order at night, the soldier will feel about in the dark and open the illuminating lamp in bedroom, corridor and garage, can influence fire-fighting and set out speed.

The utility model content

The purpose of this utility model is the problem at above-mentioned prior art, at first provide a kind of 119 fire alarm fire-fightings and set out the intelligent linkage controller, realize that fire alarm sets out the interlock of order and alarm bell and relevant illuminating lamp, thereby improving fire brigade rapid-action speed, secondly is to make this controller also can be used for the control of fire brigade daily life electric bell.

For achieving the above object, solution of the present utility model is as follows:

This linkage controller is serially connected in audio frequency trigger circuit in computing machine audio amplifier and sound card or telephone wire and the terminal box link circuit, is connected on the delay driving circuit of this audio frequency trigger circuit output terminal and is connected on the alarm bell of delay driving circuit output terminal by one and the execution relay J 1 of relevant illuminating lamp constitutes.

Above-mentioned sound signal trigger circuit are made of two photoelectric isolating devices.

The also subsidiary life electric bell interlock of this linkage controller control module, this control module are by time block and be connected on level shifting circuit, triggering driving circuit and the life electric bell execution relay J 2 that this time block triggers output terminal successively and constitute.

Characteristics of the present utility model are:

1, realized starting alarm bell and relevant illuminating lamp automatically, thereby realized that fire alarm sets out the interlock of order and alarm bell and relevant illuminating lamp, set out to provide advantage fast for fire brigade with computing machine fire alarm prompt tone or phone ringing sound.

2, this controller adopts the photoelectricity isolation method to carry out the collection of trigger pip, makes the work not influence of the installation of this controller to computing machine or telephone communication network.

3, the also subsidiary control function that has timing to start life electric bell of this controller can promote the robotization of fire brigade life management.

Embodiment

Describe structure of the present utility model and principle of work in detail according to embodiment below.

Referring to Fig. 1,2, described sound signal trigger circuit 1 have adopted a two photoelectric isolating device TPL521-2, its two input end A, B are serially connected in the link circuit of computer sound card and audio amplifier or telephone set and terminal box, when computing machine sends telephone bell that alert prompt tone or fire alarm set out order and sounds, sound signal is carried in input end A, the B of this pair photoelectric isolating device, two lumination of light emitting diode then, corresponding simultaneously photosensitive receiving tube receives this luminous signal and conducting, and from high trigger signal of its output terminal C output.This controller uses two photoelectric isolating devices to finish this controller and being electrically connected of trigger pip equipment is provided dexterously, this electrical connection only is equivalent to be connected in series the light emitting diode of two reverse parallel connections in the link circuit of computing machine audio amplifier and sound card or telephone set and terminal box, because the tube voltage drop very little (less than 0.7V) of these two light emitting diodes, so can not produce any influence to the equipment that trigger pip is provided, and this connection also need not consider to connect polarity, and is easy for installation.Described delay driving circuit 2 is monostable circuits that are barricaded as by 555 time base circuits, the delay time constant is arranged on (because the fire-fighting attack time is no more than one minute) within one minute, its triggering input end (2 pin) joins with two photoisolator output terminal C by a current-limiting resistance R1 with by the anti-jamming circuit that resistance R 2, capacitor C 1 are connected into, and described execution relay J 1 is connected on the time-delay output terminal (3 pin) of this monostable circuit.When this controller was awaited orders, monostable circuit was in stable state, i.e. 3 pin output low levels, and relay J 1 dead electricity, alarm bell stops ringing and relevant illuminating lamp extinguishes; When two photoelectric isolating devices 1 are exported trigger pip, this monostable circuit upset, its 3 pin output high level, then relay J 1 gets electronic work, and alarm bell is reported to the police, and the illuminating lamp of being correlated with is bright; After the time-delay (1 minute), monostable is turned into virgin state automatically, and then alarm bell stops, and relevant illuminating lamp extinguishes.Sound all clear if in delay time, want, can be with linked switch K, K ' closure, wherein K short circuit sound signal is immediately extinguished light emitting diode, and K ' will reduce charging resistor, just shorten the delay time constant, make delay capacitor C2 be full of electric charge in advance, 7 pin are put height, then the monostable virgin state of overturning back immediately, 3 pin become low Gao Ping rapidly, alarm bell are stopped and the illuminating lamp of being correlated with extinguishes.This function can be used for hand-operated forced cut-out interlock or make reporting hand-reset immediately by mistake.

Again referring to Fig. 1,2, described time block 4 adopts TIMESTAR piece moulds, when it can show, minute, second, week etc., and can set six timing signals of output in one day, and this timing signal is exported with square wave, and the upper edge of square wave is for opening signal, and the lower edge is the pass signal; Described triggering driving circuit 6 is bistable circuits that are connected into by 555 time base circuits, because the signal level of time block output is not more than 0.7V, be not enough to trigger this bistable circuit, so added a level shifting circuit 5 between time block and bistable circuit, life electric bell is carried out the output terminal (3 pin) that relay J 2 is connected on bistable circuit.When time block is exported a timing signal according to the time that sets, behind level translator, the bistable circuit upset is triggered in its upper edge, then 3 pin are exported high level, the J2 action, and life electric bell rings, after ringing certain hour (width of square-wave signal), the lower edge of timing signal makes the bistable state Inversion Recovery again, J2 dead electricity then, and life electric bell stops.

Referring to Fig. 2, sequence number 8 is power circuits of this controller among the figure again, and rectification and the voltage stabilizing of the filtering of electric capacity and voltage-stabilizing device IC1 of the mains supply of 220V by the bridge diode full wave rectifier provides a galvanic current to press to this controller to power.
