Abstract
The utility model relates to an alarming unit which directly alarms by a speech. The alarming unit makes alarming status reports be intuitive, rate of false alarm be low and alarming ways and alarming times be unlimited. The alarming unit adopts an integrated speech signal generator, the alarming status detecting part adopts the double monitoring control of voice and light, and can automatically monitor on site, making the operational reliability of the whole alarming unit enhanced. The utility model has the advantages of convenient operation and low cost, and the alarming unit is suitable for various places, in particular to be convenient for being popularized in a family.
Description
The utility model is a kind of warning device of directly automatically reporting alert with language.
No matter wired existing warning device is, wireless transmission, adopts signal sound to report to the police mostly, the pilot lamp indication, and this type of alarm, intuitive is poor, and way is restricted.Concerning wire transmission, if want the multichannel will be multi-thread, trouble be installed, circuit fee often causes wrong report because of the installation quality difference with height.Concerning wireless transmission, be subjected to the restriction of frequency range, " dead angle " that has electric wave to be shielded, the frequency division difficulty, string road situation is comparatively serious, and way is restricted, and is subject to disturb, and causes wrong report, and the cost of device is higher, has influence on practicality and popularization.
The purpose of this utility model is to provide a kind of intuitive strong, reliable operation, and rate of false alarm is low, and the warning way is unrestricted, warning device with low cost.
The technical solution of the utility model is: signal generator adopts integrated speech signal generator.Utilize the Protean characteristics of speech signal, different language is used in different alerts, place, it is directly perceived to report to the police.
Alert detection circuit of the present utility model is the infrared two monitoring system circuit of a kind of ultralow frequency frequency-selecting acoustic control and fixed frequency.
The utility model is to the on-the-spot realization of alert AM automatic monitoring.
This warning device is directly reported alert place and character automatically with language, can stop the drawback that pilot lamp shows alert place, alert character in theory at all, intuitive is strong, wrong report and wrong number, string phenomenon can not take place, and be not subjected to the restriction of way, be how much irrelevant with main frame extension set is, manufacturing cost is reduced greatly, be suitable for family and use.Because employing sound, the two monitoring systems of light promptly monitor sound and people's activity simultaneously, have strengthened the reliability of device work, the AM automatic monitoring by to alarm set point also provides field condition to supervision department once more, is convenient to the detection of alert is handled.
Fig. 1, transmitter control principle figure.
Fig. 2, the receiver principle block scheme.
Set forth embodiment of the present utility model below in conjunction with accompanying drawing.
Microphone (1), amplifier (2), (3), (5), oscillator (4) are formed the alert detection circuit with door (7).Monitor sound by microphone (1), ultra-low frequency amplifier (2) receives the aural signal that microphone (1) sends, and delivers to an input end with (7).Oscillator (4) modulation output makes infrared light-emitting device D
1Luminous, then by photosensitive tube D
2Produce photoelectric effect, in certain scope, the surveillance operation target if people's activity is arranged, is just sent signal, delivers to another input end with door (7) through amplifier (3).When amplifier (2), (3), when having detectable signal to send simultaneously, proof has alert, overturn with door (7), open integrated speech signal generator (6), simultaneously, open electronic switch SCR1, connect active carrier oscillator (9), speech signal generator (6) repeatedly sends certain specific warning language, as " No. 235 there are robber's feelings in the place " or the like (and can change the warning language as required), this speech signal is that active carrier oscillator (9) is sent to power lead through radiating circuit, by power line carrier, the alert signal is passed to each place of this electric system (in a transformer-supplied scope), receive for the control point.
The receiving circuit of this device alert signal mainly is made up of carrier wave, reception, frequency-discriminating circuit (11), note amplifier (12), recording control circuit (13), power supply (14), sound-track engraving apparatus (15) etc.By the alert signal of power line carrier transmission, deliver to frequency-discriminating circuit (11) through capacitance C9, after note amplifier (12) amplifies, deliver to loudspeaker (16) again, the operator on duty just can hear the warning language that place of alarm is sent.Simultaneously, utilize relay of DC component control of frequency-discriminating circuit output to start sound-track engraving apparatus (15), finish the automatic record of alert signal, alert is not only accurate like this, and tape can carry out permanent keeping records, and is true and reliable, even operator on duty's inadvertent, also no mistake could arise, brought convenience to detection work.Under the situation that need not to write down, can not want sound-track engraving apparatus, receiving trap is more easy.
When language generator repetition of alarms language automatically shuts down for several times, at this moment electronic switch SCR2 connects low-frequency amplifier (5), so transfer to on-the-spot transaudient automatically, then receiving end just can be monitored, monitor also record automatically of content, the field condition AM automatic monitoring can make the operator on duty judge alert more accurately, so that take corresponding measure.
This warning device also is provided with cipher switch (10) and electronic reminding device (8), when the one of own side enters the room, electronic reminding device (8) sends sound, notify the household to dial predetermined shutoff password, allow cipher switch (10) turn-off, make the one of own side enter house and do not send alerting signal, and report to the police when illegally entering, this facilitates popularizes household alarm in the whole society.
Distinguish the character of alert, need multiple probe, every alert detecting head (the then available simple relay circuit of the probe of non-switching value signal changes into switching value) that sends the switching value signal all can be used with this warning device.Therefore if increase and the identical language integrated circuit of probe quantity, promptly can be assembled into language direct sounding type warning system, and cost improves slightly just with multiple warning function.
The utility model is by C
2, D
3, E realizes that alternating current-direct current switches, and generally adopts mains-supplied, when mains failure, can automatically switch to direct current supply, continues the holdout device operate as normal.
The utlity model has stronger versatility, if in the non-transformer area or special occasions use, can adopt wireless transmission method, at this moment only need the frequency shift of the resonance circle in transmitter circuit and the receiver circuit is become required ultra-high frequency signal, remainder is constant. If when some needs special secret place and special-purpose control, available single-core cable or lay a dedicated signal lines, realize not limitting the single line multiplexing of way, at this moment circuit is more simple, the manufacturing cost of equipment also can reduce, as long as audio signal, namely alarm language sound has enough power, and speech signal just can transmit as telephone wire. Compare with the multi-thread multiplexing mode of existing usefulness, saved a large amount of electric wires and set up expense, have secret, reliable characteristics.
