Description
Technical field
The utility model relates to the automobile automatic control device, specifically the reflective automobile collision preventing automatic control device of infrared laser.
Background technology
In people drive, often since chaufeur carelessness or fatigue cause before and after the car collision, take place for fear of this type of accident, the method that adopts usually is both at home and abroad: 1, air bag protecting device, 2, the fence operation lever apparatus, 3, crashproof automatic control device.But air bag protecting device and fence operation lever apparatus all just slow down or reduce the collision injury, and it is to control afterwards, and control setup is just to work after collision takes place.And the automatic collision control setup is that detection is put in the first place, in advance control.The existing use in the automobile collision preventing operatorless device luxury car abroad, but cost an arm and a leg, on interior low and middle-grade cars, be difficult to promote.
Summary of the invention
The purpose of this utility model provides the reflective automobile collision preventing automatic control device of a kind of infrared laser, it passes through to self speed of a motor vehicle and to the far and near detection of distance between car the place ahead obstacle or the self-propelled vehicle, realization sound, light warning and auto acceleration, deceleration, braking reach safety traffic.
The technical solution of the utility model is: the reflective automobile collision preventing automatic control device of infrared laser main composition is made up of following electric part: infrared laser transmission circuit and infrared laser acceptor circuit, micro controller system, infrared velocity pick-up circuit, operation selector button (source switch, hand, automatic selector switch), sound alarm circuit and optical alarm circuit, and clutch controller and brake controller composition; Its each part circuit all connects with micro controller system.
The reflective automobile collision preventing automatic control device of infrared laser of the present utility model, adopt Single-chip Controlling and processing, infrared light emission and reception have good in anti-interference performance to signal, stability, high reliability features, can realize safety traffic, reduce the generation of safety misadventure, realize keeping between back car and the front truck certain minor increment, i.e. safety distance, rear-end impact can not take place so that work as the unexpected glancing impact of front truck, and be applicable to high, medium and low all kinds of automobile collision preventing safety control.

The specific embodiment
As shown in the figure, the reflective automobile collision preventing automatic control device of infrared laser of the present utility model main composition is made up of following electric part: infrared laser transmission circuit and infrared laser acceptor circuit 1, micro controller system 9, infrared velocity pick-up circuit 2, operation selector button (source switch, hand, automatic selector switch) 15, sound alarm circuit 8 and optical alarm circuit 10, and compositions such as clutch controller 6 and brake controller 4; Its each part circuit all connects with micro controller system.
Wherein: the singlechip controller model is 89C51, and its input interface circuit is made up of velocity checking circuits, distance detecting circuit, reset circuit, mu balanced circuit, selector button, clock circuit, and its connecting relation as shown in Figure 2.The output interface circuit of singlechip controller is made up of speed infrared emission circuit, optical alarm circuit, sound alarm circuit, infrared laser transmission circuit, clutch control circuit, lifting speed braking circuit, and its connecting relation as shown in Figure 3.
The utility model adopts infrared reception, the radiated element of performance-oriented 850nm wavelength, and infrared lens (or lens or parabolic lens) realize to detect the distance (requirement of 1m～100m, 1m～70m, 1m～50m).Projector and receptor are contained in the same box, are installed on the appropriate location, dead ahead of automobile.Power-transfer clutch is by the magnet control of controller drives, and drg is realized automobile acceleration, deceleration and braking by the driving bindiny mechanism control based on motor of controller drives.
Principle of work: the infrared laser projector sends the laser pulse of certain wavelength, laser pulse is run into front automobile or obstacle, the laser diffuser reflection is got back to infrared laser receptor (projector is installed in by the receptor), the infrared laser receptor is converted to the backward wave that receives electricity, amplifies then, sends into the micro controller system auto mat.Infrared speed sensor is sent into the micro controller system auto mat to the speed pulse signal of current detection.Range signal and infrared speed sensor speed pulse signal that the micro controller system auto mat is sent the infrared laser receptor here carry out computing, comparison, judgement, provide current car running velocity and the place ahead situation, have or not automobile or obstacle as the place ahead, apart from what.When the distance between back car and the front truck less than back speed of a motor vehicle control apart from the time, controller sends sound, light is reported to the police, the prompting driver's operation is slowed down; When distance greater than current vehicle speed control apart from the time, driver's operation accelerates to given running velocity.If chaufeur is neglected operation, controller is controlled performer and is made power-transfer clutch, drg action, changes the running state of current automobile, realizes acceleration, the safe in operation that slows down, brakes, and avoids the generation of safety misadventure.
Working process: 1) M/C: energized is chosen in manual state.Sound, light that chaufeur sends according to controller are reported to the police, the acceleration, deceleration and the braking of operation automobile.2) operation automatically: energized is chosen in auto state.Chaufeur can be by normal M/C.If chaufeur carelessness or other reason, so that send under the prompting of sound and light alarm at controller, chaufeur does not have M/C, and controller can be realized automobile acceleration, deceleration and braking according to detected apart from situation, reaches safe automatically controlled purpose.
