Description
The utility model relates to car steering security alarm field.
What the multi-purpose vehicle(MPV) driver drowsy alarm that is proposed according to existing application (patent) 91220161.4 adopted is helmet-type transmitter and organization switch formula anti-theft puzzle lock.Because general driver feels inconvenient to using the helmet-type transmitter, most drivers are reluctant to use.Its mechanical switch formula theftproof lock confidentiality is poor, easily decodes, and receiver only is common superregenrative reception mode in addition, and interference free performance is poor, is subject to the engine spark and disturbs.
The purpose of this utility model is to improve above-mentioned the deficiencies in the prior art.Provide a kind of and wear conveniently, antijamming capability is strong and have the multi-purpose vehicle(MPV) driver drowsy alarm of anti-theft capability.
The utility model is made up of transmitter and controller two parts.Transmitter adopts the very high frequency(VHF) transmitter of secondary modulation, can be installed in the leg of spectacles that the driver wears.Transmitter is made up of modulator (1), oscillator (2), liquid sensor (3), power supply (4).Modulator (1) is modulated the frequency signal of oscillator (2), and liquid sensor (3) is as the switch of power supply (4).
Controller is by receiver (5), secondary demodulation device (6), time arbiter (7), alarm (8) in the car, the outer alarm 914 of car), pause switch (10), four electronic password locks (9), recognizer (11), control circuit (12), topworks (15) forms, receiver (5) receives from after the sub-radiofrequency signal of transmitter, send secondary demodulation device (6) to carry out secondary modulation, time of delivery (TOD) arbiter (7) is finished or is discerned again, arbiter (7) compares the duration of input signal and the time of setting, controller (12) is delivered in sleepy signal output, and controller (12) is distinguished shallow degree drowsiness and sleepy signal of the degree of depth and difference again, control, outer alarm (14) of alarm (8) or car and topworks (15) in the car.
Four electronic password lock employings are digital, send recognizer the password of input, after recognizer is identified as correct password, the recognizer via controller provides a correct signal, the cut-in point ignition source can be lighted a fire, and car starts, when recognizer thinks that the password of being given is wrong, just send error signal, car can't start, and the driving of going forward side by side is outer reports to the police, microphone (13) can directly be given orders or instructions outside car, so that other car is defeated and the pedestrian arouses attention and prevent road block.
The present invention adopts the spectacle transmitter, and is in light weight, wears conveniently, can the sleepy signal of comprehensive detection.On interference free performance, adopted the mode of secondary modulation and demodulation, interference free performance is improved greatly, even in the serious environment that disturbs, also can normally use.Its anti-theft puzzle lock adopts group of four figures coding, so its confidentiality improves greatly, all uses the CMOS integrated circuit at signal processing, has low-power consumption, highly reliable characteristics.
Following drawings and Examples are described in further detail the present invention:
Accompanying drawing 1 is the circuit block diagram of preferentially selecting embodiment for use of transmitter of the present invention.
Accompanying drawing 2 is circuit block diagrams of controller of the present invention.
Fig. 3 is the physical circuit figure of transmitter;
Fig. 4 is the physical circuit figure of controller;
Transmitter (16) is modulated the frequency signal of oscillator (2) by modulator (1), by the switch of liquid sensor (3) as power supply (4), and control transmitter (16) work.During use, transmitter (16) is contained in driver's the leg of spectacles when driver drowsy, nose drop sensor (3) thus tilt energized (4), an adjusting wave signal is carried out exporting the very high frequency(VHF) signal by oscillator (2) after the secondary modulation.As shown in Figure 2, liquid sensor (3) adopts the mercury sensor, modulator (1) adopts NL200, after receiver (5) receives radiofrequency signal from transmitter as shown in Figure 2, carry out secondary modulation through secondary demodulation device (6), signal time of delivery (TOD) arbiter (7) after the demodulation is finished or is discerned, arbiter (7) compares the duration of input signal and the time of setting, sleepy signal is delivered to control circuit (12) from output terminal, and shallow degree drowsiness distinguished by control circuit (12) and alarm (8) or outer alarm (14) of car and topworks in the car are controlled in degree of depth drowsiness respectively.
The physical circuit of controller as shown in Figure 4.Receiver (5) is BG
1The superregenerative reception device, the signal after the detection is at R
3, R
3Between output, CD4069a, 4069b constitute amplifier, and the low frequency signal after the detection is amplified, and make the signal that enters the secondary demodulation device have enough amplitudes, assurance detuner operate as normal.The secondary demodulation device adopts the LM567 audio decoder, to improve antijamming capability.When the local frequency of low frequency signal frequency after the detection and LM567 near the time, circuit has very strong catch lock ability, and makes the local frequency of LM567 equal incoming frequency, circuit enters lock-out state, at this moment the 8 pin output low levels of LM567.Described time arbiter (7) adopts counter CD4060, and control circuit (12) comprises thick film circuit NL201 and register CD4015B; " 9 " pin of thick film circuit NL201 links to each other with " Qn " of CD4015B end, and " 12 " pin is by amplifier 4069e, 4069f, BG
3FM is communicated with hummer.Described pause switch is by light emitting diode G
1And general circuit switches set formula, G
1Link to each other with " 2 " pin of thick film circuit NL201." 8 " pin of " 1 " pin of NL201 and LM567 inputs to the R end of time arbiter CD4060 through circuit CD4071a.
Enter lock-out state at LM567, under the situation of " 8 " pin output low level, when " time-out " key is late for G
1Luminotron extinguishes, and " 1 " number pin of thick film circuit NL201 is output low level also, so its Gn end output high level behind the about 1S of counter CD4060 startup.At this moment " 12 " pin of NL201 is a high level, and hummer FM sends chimes of doom, and this process is equivalent to sensor acquisition and arrives the once process of sleepy signal, and this time sleepy signal is delivered among the register CD4015B.The outer alarm of car is made up of warning circuit KD-4 and loudspeaker, and KD-4 is by controllable silicon BG
2" Q with register CD4015B
2" pin links to each other.Four electronic password locks (9) and recognizer (11) comprise thick film circuit NL202 and register CD4015A.Topworks is made up of the relay road J and the diode of parallel connection, and they link to each other with " 3 " pin of thick film circuit NL202.If in 1 minute, secondary or three so sleepy signals appear, at the Q of register CD4015B
2Pin output high level triggers controllable silicon BG
2Conducting.Chimes of doom circuit KD-4 work, the alarm sound of in loudspeaker, sending out strong.Thick film circuit NL202 " 3 " number pin is high level output simultaneously, makes the relay J outage, and its contact discharges and the priming supply of engine is cut off, and " 11 " pin of thick film circuit NL201 links to each other with the R of counter CD4015B end.
If at 1 minute timer, secondary or the sleepy signal more than three times do not appear continuously at this moment, and thick film circuit NL201 " 11 " pin is exported high Anping, and the content of having deposited in the register is removed.Sleepy signal-count is restarted.
Thick film circuit NL202 is four electronic password locks, have only by the program of unblanking of pre-input and just can unblank after by the keyboard input, at this moment actuating of relay car can start, and there is requirement the time to the keyboard input, if in official hour, can not import correct coding, electronic lock can not be opened equally.On keyboard, be provided with antitheft key, as long as the anti-key of stealing down,, and make car enter warning, off-position no matter all can automatic cutout at what state relay.
