Abstract
The present invention relates to an automatic brake anticollision system for vehicles. Said system is composed of signal transmitter circuit, signal receiver circuit, brake mechanism and detector. When the distance between two vehicles is less than a set value, its signal inductor can convert the electromagnetic wave or light wave or sound wave signal transmitted by signal transmitter and received by signal receiver into electric signal to transfer it to brake mechanism to implement automatic brake, so that it can effectively prevent vehicles from colliding against each other.
Description
The present invention relates to the anticollision safety method of transport facilitys such as a kind of automobile, train.
At present, the protection safety measure of automobile only is confined to prevent collide back personnel's injures and deaths such as safety strap, air bag etc., and not only personal casualty can't be eradicated, and automobile itself can not get protection, and the traffic accident of car crash increases year by year.
Purpose of the present invention is exactly in order to eradicate collision.Thereby avoid vehicle breaking-up, personal casualty.
The present invention sends continuous electromagnetic wave or light wave or sound wave signals such as (as super sonic, infrasounds) with signal projector.When two spacings during less than certain value, signal inductor will be received signal and it is changed into electric signal, passes to braking mechanism after amplifying, and causes self-actuating brake.
The installation site of signal projector, inductor and the waveform that is sent are shown in figure one, and wherein dash area is for causing the scope of self-stopping ripple, and relevant circuit is seen figure five, six.
Native system has three kinds of modes of action:
(1) passive brake.See figure two.This mode can solve collides end to end and head-on crashes.
The condition that realizes this mode is: all vehicles all need be installed native system, and inclination angle, the bottom surface A of the ripple of the setting height(from bottom) h1 of signal projector, inductor, h2, emission, the included angle B of liquid, braking distance l, the mounting distance a of signal projector, the frequency of signal etc. all has unified regulation.H1 wherein, h2 is generally highly definite by car: l stop according under maximum speed, braking to the distance of process determine, and leave certain safe clearance; A is determined by the general width of car; Determine B, tgB=a/l by a, l: determine A by l, h1.tgA＝h1/l。
Among the figure two, car 7,8 is to right travel, car 9 left, all on same straight line.Motor-driven switch among the figure five, six 15,16 is all closed at this moment.
When the spacing of car 7,8 during less than l, the signal inductor 1 on the car 7 is received the signal that the signal projector of car 8 afterbodys sends, closing period relay 19 after amplifier 18 amplifies, and the brakes on mechanism circuit causes self-actuating brake.Because the effect of outage time lagged type time relay 19, the braking mechanism circuit will automatic cutout after car stops, braking mechanism resets.So just can avoid car 7 to run into car 8 from behind.
When the spacing of car 8,9 during less than l, the signal inductor of car 8,9 front portions all can be received the signal that the signal projector of the other side front portion sends and brake simultaneously so just can prevent to head on and clash.
(2) central collision is initiatively braked.See figure three.This mode also can solve rear-end collision and head-on head-on collision.Car 10 is equipped with native system, and car 11 does not have dress.
When the spacing of car 10,11 during less than l/2, the signal that send car 10 front portions is received by the signal inductor of car 10 front portions through car 11 reflection backs, makes car 10 self-actuating brakes, in order to avoid collide.
(3) oblique impact is initiatively braked.See figure four.Can solve oblique impact.
When the spacing of car 12,13 during less than l, the signal of car 13 anterior signal projectors emissions by the reception of the signal inductor of car 13 front portions, makes car 13 self-actuating brakes, in order to avoid oblique impact through car 12 reflection backs.
The difference of mode (2), (3) and (1) is that (2), (3) do not require that all cars all install native system.
Purpose by angle A, B restricting signal transmitting boundary be avoid making cannot and car other vehicle mistake of colliding collect mail and number brake, operating angle C is in order to prevent that the car mistake from receiving the signal that oneself sends.Signal projector before and after the car should symmetry be installed.
Motor-driven switch 15,16 auto-closings after the car starting, signal emission, acceptor circuit are connected simultaneously, and signal projector sends continuous signal, and inductor is also started working.Two circuit automatic cutouts in the time of to stall.
The effect of hand switch 14 is to stall the time, still can send signal, and this car that just can prevent other is run into oneself.Should closed this switch during traffic congestion on the express highway.
Explanation about verifier: verifier is an annex independently, is mainly used in the scope of adjusting ripple when signal projector is installed, and checks whether normal operation of native system.It is made up of two parts, and figure seven is that acceptor circuit verifier figure eight is the transmission circuit verifier.When signal projector is installed, connect transmission circuit earlier, launch the ripple of certain limit, when signal inductor 22 entered in the ripple, indicator lamp 24 can be lighted suddenly, so just can adjust the scope of ripple.When checking the service condition of native system, the closed transmission circuit of elder generation, acceptor circuit.If working properly, when inductor 22 entered in the ripple, indicator lamp 24 can be shinny: car was slowly advanced, and when the signal of signal projector 21 emissions was penetrated on signal inductor 1, car can self-actuating brake.
The intensity of the signal of signal projector emission is in the intensity of distance l planted agent greater than the general electromagnetism glistening light of waves, sound wave, and general electromagnetic wave, light, sound wave can not the energizing signal inductor.Its triggering also can realize by wave frequency is controlled.
Because the mature technology (as: telecontrol engineering of vision receiver, electro-optical tubes etc.) of now existing signal projector, receptor omits their concrete structure here.
Compare with prior aries such as safety strap, air bags.The present invention not only can protect the safety of people in the car better, and can make vehicle itself avoid damaging, and can reduce traffic accident and economic loss in large quantities.
