Abstract
The invention discloses a laser ranging automotive emergency deceleration system. The laser ranging automotive emergency deceleration system comprises a processing control module, a switch module, a sound-light alarm module, a helium-neon laser transmitter, a laser receiver, a motor driving chip, an automotive brake mechanism and a power converter, wherein the processing control module is connected with the switch module, the sound-light alarm module, the helium-neon laser transmitter, the laser receiver and the motor driving chip, the motor driving chip is connected with the automotive brake mechanism, the switch module is connected with an automotive battery through the power converter, and the helium-neon laser transmitter and the laser receiver are installed at the top end of an automotive. By the aid of the method, the system can help a driver to detect the relative height of a barrier when the driver does not know the barrier ahead, if the height is not sufficient, automatic speed reduction is conducted, prompts are put forward, and the driver can get ready in advance, so that an accident can be avoided.
Description
Technical field
The present invention relates to the automotive engineering field, particularly relate to a kind of laser ranging car emergency deceleration system.
Background technology
Now, the structure species of automobile is quite extensive, and the road plan of establishment is fixed.A full-sized car must have a lot of objective problem to need to consider before road travels, and expects fully surely but the obstacle that runs in motion but differs.And sometimes, abominable natural situation more can allow the highway section of being familiar with thicken.Thereby, the goods of some high capacity waggons or warehouse often occurring the mark post in roadside is rubbed down, serious some lorries that also occur are stuck under tunnel or the bridge pier, and are in a dilemma, had a strong impact on safety traffic.
Based on this present situation, the mode of this novel employing laser reflection location, remote at a distance of suspicious obstacle or because environmental aspect, when the driver does not know that there is obstacle in the place ahead, detect its relative height, if insufficient height, automatic retarding then, and provide prompting, make the driver ready in advance, thereby avoided the generation of accident.
Summary of the invention
The technical matters that the present invention mainly solves provides a kind of laser ranging car emergency deceleration system, can help the driver when not knowing that there is obstacle in the place ahead, detect its relative height, if insufficient height, automatic retarding then, and provide prompting, make the driver ready in advance, thereby avoided the generation of accident.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of laser ranging car emergency deceleration system is provided, this laser ranging car emergency deceleration system comprises processing and control module, switch module, sound and light alarm module, He-Ne Lasers projector, laser pickoff, motor drive ic, automobile braking mechanism and power supply changeover device, connecting switch module, sound and light alarm module, He-Ne Lasers projector, laser pickoff and motor drive ic on the described processing and control module, described motor drive ic is connected with automobile braking mechanism; Described switch module is connected to automobile storage battery by power supply changeover device; Described He-Ne Lasers emission and laser pickoff are installed on the automobile top.
The invention has the beneficial effects as follows: a kind of laser ranging car emergency of the present invention deceleration system, adopt the mode of laser reflection location, remote at a distance of suspicious obstacle or because environmental aspect, when the driver does not know that there is obstacle in the place ahead, detect its relative height, if insufficient height, automatic retarding then, and provide prompting, make the driver ready in advance, thereby avoided the generation of accident.
Description of drawings
Fig. 1 is the structural representation of a kind of laser ranging car emergency of the present invention deceleration system;
Fig. 2 is He-Ne Lasers projector and the installation site scheme drawing of laser pickoff on automobile of a kind of laser ranging car emergency of the present invention deceleration system;
Fig. 3 is the He-Ne Lasers transmitter circuit scheme drawing of a kind of laser ranging car emergency of the present invention deceleration system;

The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that the advantage of invention and feature can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1 to Fig. 4, the embodiment of the invention comprises:
A kind of laser ranging car emergency deceleration system, this laser ranging car emergency deceleration system comprises processing and control module 1, switch module 2, sound and light alarm module 3, He-Ne Lasers projector 4, laser pickoff 5, motor drive ic 6, automobile braking mechanism 7 and power supply changeover device 8, connecting switch module 2, sound and light alarm module 3, He-Ne Lasers projector 4, laser pickoff 5 and motor drive ic 6 on the described processing and control module 1, described motor drive ic 6 is connected with automobile braking mechanism 7; Described switch module 2 is connected to automobile storage battery by power supply changeover device 8; Described He-Ne Lasers emission 4 and laser pickoff 5 are installed on the automobile top.
A kind of principle of work of laser ranging car emergency deceleration system is: when automobile during in normal highway section normal driving, and device for opening switch not, device is in off position; When finding the place ahead segment distance far away, the driver has short obstacle, when can difficult judgement be passed through, and the master cock of device for opening.At this moment, laser transimitter begins to launch low level laser, if can pass through, does not then have any response; Highly be lower than bodywork height when laser pickoff detects it, just signal passed to processing and control module, processing and control module is received signal, sends instruction to motor drive ic, makes automobile braking mechanism work, and with car deceleration, the warning indicator lamp begins to flash; When the driver finds situation, in time stop or reverses its direction, turn off master cock, device is no longer worked, and problem is just solved.
A kind of laser ranging car emergency of the present invention deceleration system can help the driver when not knowing that there is obstacle in the place ahead, detects its relative height, if insufficient height, automatic retarding then, and provide prompting, make the driver ready in advance, thereby avoided the generation of accident.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification sheets of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
