Embodiment

Below in conjunction with embodiment, the utility model is elaborated.

Motor-vehicle accident autoalarm of the present utility model as shown in Figure 1, comprise the pick-up unit 1 and the signal processing apparatus 2 that are connected successively, signal processing apparatus 2 is connected with respectively acoustic-optic alarm 3, position detecting device 4 and 3G communication module 5, and wherein 3G communication module 5 adopts the EM660 of Huawei.

As shown in Figure 2, pick-up unit 1 comprises rollover sensor 11, crash sensor 12, humidity sensor 13 and the smoke transducer 14 that is connected with signal processing apparatus 2 respectively.

Signal processing apparatus 2 comprises the first single-chip microcomputer 21 and the filter and amplification module 22 that is connected successively, and wherein the model of the first single-chip microcomputer 21 and filter and amplification module 22 is respectively STC89C52 and TLC04.

Acoustic-optic alarm 3 comprises loudspeaker 31 and flashlamp 32.

As shown in Figure 3, rollover sensor 11 comprises power supply 101, fixed resistance 102, slide rheostat 103, switch 104, reometer 105, A/D modular converter 106 and the second singlechip 107 that head and the tail are connected successively, switch 104 belows are connected with Metal Ball 109 by montant 108, Metal Ball 109 contacts with the upper surface of vehicle frame 111, and the arranged outside of Metal Ball 109 has tubular fixed mount 110.

Wherein the model of A/D modular converter 106 is ADC0809, and the model of second singlechip 107 is AT89S52.

When automobile normal running, Metal Ball 109 under the self gravitation effect with the Surface Contact of vehicle frame 111, Metal Ball 109 applies downward pulling force by montant 108 to switch 104, makes switch 104 be in off-state, rollover sensor 11 is not worked.

When automobile occurs tilting because of fortuitous event in the process of moving, when the angle of inclination of automobile was interior in not dangerous scope, Metal Ball 109 can be along with the inclination of automobile in the interior motion of fixed mount 110, and montant 108 moves thereupon, the change in location of pull switch 104, but switch 104 is not closed; And when tilting of automobile to dangerous angle, until in the process of overturning, Metal Ball 109 moves to the opening direction of fixed mount 110 under action of gravitation, montant 108 is along with movement, pull switch 104 closures, this moment, rollover sensor 11 was started working.

Crash sensor 12 is when automobile bumps, and detects the strength signal of car crass.The principle of crash sensor 12 is identical with acceleration transducer, generally by the piezoelectric manufacturing, when after adding load on specific direction, can cause that charge distribution is uneven, judges what of load and then the size of judgement acceleration by the size of measuring electric charge.If acceleration has surpassed predefined threshold value, just explanation is abnormal deceleration, and namely collision accident has occured automobile.

Crash sensor 12 also can adopt the crash sensor of inertia-type mechanical switch structure or other types.

Humidity sensor 13 is used for judging whether accident vehicle is under water.Rational humidity threshold value is set, if surpass threshold value, thinks that the accident automobile drops in water, the rescue personnel can carry out the rescue preliminary work of persons falling in water and vehicle in advance.

Smoke transducer 14 converts airborne smokescope variable to the voltage signal output of certain corresponding relation.Judge according to the concentration of smog whether accident vehicle is on fire, prepare so that when rescue carried out fire extinguishing.

Signal processing apparatus 2 comprises the first single-chip microcomputer 21 and filter and amplification module 22.Various sensors produce signal through the processing of the first single-chip microcomputer 21, then send to acoustic-optic alarm 3 and position detecting device 4 and 3G communication module 5 with suitable form after the processing of filter and amplification module.

Acoustic-optic alarm 3 comprises respectively loudspeaker 31 and flashlamp 32, and the hummer that loudspeaker 31 adopts on automobile after it receives the signal of signal processing apparatus 2, will be reported to the police with the flicker light beam by sending alarm sound respectively.

Position detecting device 4 is used for the location accident spot, and what this device mainly used is vehicle mounted GPS guidance system.According to cartographic information and the real-time satellite information that receives of storage, determine concrete, the detailed geography information when the vehicle in front position.Gps system is made of satellite, monitoring station, main control station, ground-plane antenna and signal receiver.As the user, we only need to buy signal receiver and just can use.

Be inserted with the 3G card with car owner's cell-phone number jack per line in 3G communication module 5, store relevant target mobile phones number in card, process the related personnel's such as department and kith and kin telephone number as traffic hazard.3G communication module 5 is issued relevant departments and related personnel with the accident vehicle position, accident condition and the pre-stored Word message that receive with the form of note, to show emergency.

By the way, motor-vehicle accident autoalarm of the present utility model solved prior art can't be initiatively, accurately, the problem that at length motor-vehicle accident information in time sent.And take full advantage of the elements such as existing GPS navigation system, hummer, flashlamp and accumulator on automobile, make native system with low cost, and can give full play to the effect of existing equipment on automobile.And place and status information that can the real-time report accident vehicle be rescued driver and crew timely and effectively, effectively reduce mortality ratio and the disability rate of motor-vehicle accident.
