Description
Technical field
The utility model is put it briefly and is related to the technology of a kind of audio alert and on-the-spot emergency command.
Technical background
Along with the enhancing of people's fire-fighting consciousness, the strick precaution of fire is more and more paid attention to, it is related to people's lives and properties after all, and fire-fighting work is the heavy again of weight really; However, fire still happens occasionally, and when fire took place, existing technology was the signal that on-the-spot smog probe is sent here, makes the acoustooptic alarm system response, and buzzer sends strong screaming, and indicator lamp is glittering simultaneously.At this moment administrative staff are on the scene with the fastest speed according to the position of indicator lamp indication, propaganda directed to communicate with mouth, at most also are to propaganda directed to communicate the commander Field Force to evacuate with hand microphone, assemble the fire fighting personnel and drop into rescue work, comprise that certainly dialling 119 requires assistance.But the scene of a fire such as battlefield, complete confusion often, by the time the fire fighting personnel are on the scene, some times have been delayed, add and propaganda directed to communicate, seem too small and weak, evacuate no matter this is the commander Field Force at this very noisy environment, still assembling, command the fire fighting personnel to drop into rescue work, all is unsatisfactory.
The utility model content
The purpose of this utility model is to restrain traditional acoustooptic alarm system and current scene of adopting the propaganda directed to communicate deficiency and the shortcoming of comand way, provide a kind of can flash lamp flicker report to the police and the buzzing prompting, again can with voice mode inform promptly, repeatedly the concrete site of an accident of people, and commander near personnel how to evacuate and the commander in chief that saves oneself and put out a fire can make the full-automatic fire alarm scene emergency evacuation voice command system of floor manager with mobile phone or wireless microphone.
The on-the-spot emergency evacuation voice of the full-automatic fire alarm of the utility model command system, it commands circuit, wireless microphone to command circuit, power amplifier and loudspeaker, flash alarm circuit and buzzer additional alarm circuit, power supply circuit etc. to form at a distance by control panel, input circuit, input scan and coding circuit, voice IC playback circuitry, phone at a distance.In case catch fire, the smog in the place that catches fire probe is sent signal here, these voice command system will make buzzer ring several, flash of light simultaneously near constantly flicker, high-power loudspeaker are also constantly play catch fire address and commander how personnel evacuate, save oneself; After the fire fighting commander in chief reaches the spot, can make floor manager with mobile phone or wireless microphone, repeatedly broadcasting.
The on-the-spot emergency evacuation voice of the full-automatic fire alarm of the utility model command system, its described control panel are by casing (1) and be installed in the lip-deep various control buttons of casing, indicator lamp, switch, socket, built-in miaow head (12), loudspeaker (13) and form.Button has: stop dodging that button (21), commander reset (22), player button (5), stop button (6), SR (3), record button (7); Indicator lamp has: input indicator (26), voice IC working station indicator (11), segment addressing locking indicator lamp (4), and input indicator is the light emitting diode on one on every road; Switch has: power switch (15), call command change-over switch (23), external speaker volume adjustment knob (14), built-in miaow head or outside line recording change-over switch (8), recording playback sound change-over switch (10); Beginning (25) is switched in the input that every road is; Socket has: outside line recording socket (9); It has with the wiring in the external world: be connected wiring (24) (totally 128), connection 220V power supply wiring (16), connection outside high-power loudspeaker wiring (18), the connection 220V alternating current buzzer wiring (19) of each road smog probe, connect the wiring (20) of the outer over-lapping stitch of telephone set, connect 220V alternating current flash lamp wiring (17).
The on-the-spot emergency evacuation voice of the full-automatic fire alarm of the utility model command system, its described input circuit, every route: " closed type " Connection Block (169), change-over switch (25), anti-interference capacitor (170), pull-up resistor (167,168) and buffering triode (172), current-limiting resistance (171), light emitting diode (26), optically-coupled triode (173) are formed; Change-over switch (25) is divided third gear, correspondence: " normally ", " disconnection " and " test "; Dial when " normally " when change-over switch (25), this road is in normal running status; Dialling when " disconnection " when change-over switch (25), does not come into operation in this road; When change-over switch (25) is dialled when " test ", this road indicator lamp (26) is bright, optically-coupled triode (173) output is closed, buzzer (63) sound several, while flash lamp (62) constantly glimmer, if at this moment recording playback sound change-over switch (10) is in " broadcast ", play the voice content how near personnel catch fire address and the commander are evacuated, save oneself constantly, repeatedly just begin to play; If at this moment recording playback sound change-over switch (10) is in " recording ", can pass through miaow head (12) or outside line, voice recording is carried out on this road.
The on-the-spot emergency evacuation voice of the full-automatic fire alarm of the utility model command system, its described input scan, coding circuit, it is by oscillating circuit (34,36,35,37), 24 binary counters (38,39) connection level constitutes the decoder (30) of 7 binary counters, 16 outputs, 8 choose 1 variable connector (44), and 2 latch (40,43) and 16 * 8 driving switch matrixes (27) are formed.When smog probe in a certain road is sent signal here, optically-coupled triode (173) output on this road is closed, input scan and coding circuit carry out column scan and line scanning to switch matrix, produce this road corresponding codes, and produce a low level control signal output (45), the 1 the tunnel removes to control the bistable shape circuits for triggering (33) of oscillating circuit work, makes it be output as high level, makes it suspend scanning; The 2 the tunnel removes latch (40,43), and coding is latched; The 3 the tunnel triggers flip and flop generator (56) upset of control buzzer (63) and flash lamp (62), is output as high level, makes flash of light control module (61) work on the one hand, constantly flicker of flash lamp (62) beginning; On the other hand, add a pulse signal for thyristor (64) trigger electrode of control buzzer work, make thyristor (64) conducting several seconds, buzzer (63) rings several, and reminds people is noted; The 4 the tunnel through coupling capacitance (48,53), trigger flip and flop generator (54) upset, the output high level, again through playback switch (10), remove voice IC playback circuitry, voice IC playback circuitry is encoded according to correspondence, select corresponding voice segments to play, this section speech play finishes, and the state pin (67) of voice IC is sent a high level signal back to, after phase inverter (50) is anti-phase, trigger the bistable shape trigger (33) of control oscillating circuit work, make it be output as low level, oscillating circuit is started working again, scanning circuit continues scanning forward, when being scanned up to last road, counter in the scanning circuit automatically resets, and scanning starts anew again, repeats above-mentioned action, play second time, the 3rd time------circulation is continuous, repeat playing; Near personnel (guest), hear broadcasting after, will command according to voice, hasten to flee the scene, the working unit personnel, hear broadcasting after, also can hurry to the scene and drop into the fire fighting rescue work; If selecting 1 variable connector IC (44) to change 16 into 8 selects 1 variable connector IC, latch makes 8 into, and memory is increased to 16, and smog probe sum can reach 256 the tunnel.Certainly, if amount of memory is reduced, also can make 16 the tunnel, the 32 tunnel, the 64 tunnel.
