Abstract
The utility model relates to a collision warning device based on visual analysis, which comprises a microprocessor unit (2), a vision sensor (1), an audible alarm unit (3), a signal acquiring unit (5) and a display unit (4), wherein the microprocessor unit (2) is respectively connected with the vision sensor (1), the audible alarm unit (3), the signal acquiring unit (5) and the display unit (4). The device can monitor vehicles running in the same lane in front of a vehicle through the vision sensor at any time, measures and calculates the distance between the vehicles, simultaneously collects the signals of speed, braking, steering and the like of the vehicle, and comprehensively analyzes whether collision danger exists or not; and the signal acquiring unit is used for acquiring the practical running speed signal, the braking signal or non-braking signal and the like, the device operates to acquire whether the rear-end collision danger with the front vehicle exists or not, warns a driver in different acoustooptical manners, and prevents the collision and the rear-end collision of vehicles.
Description
Technical field
The utility model relates to a kind of anti-collision warning device, particularly a kind of anti-collision warning device based on visual analysis.
Background technology
Along with the quick growth of China's economic, automobile pollution increases in the annual speed with millions of of China.Accordingly, the driver is no longer professional, and the unskilled fresh driver of many driving technologies holds inaccurately to the situation of vehicle front, anticipate not good enoughly, or fatigue driving can not in time be found the danger of knocking into the back with front truck to cause the generation of rear-end collision.Also there are not a kind of performance, the gratifying car crass prior-warning device of price at present.
The utility model content
Technical problem to be solved in the utility model is, a kind of car crass prior-warning device based on visual analysis is provided, when calculating if do not take according to the relative speed of a motor vehicle with the vehicle distances of front, vehicle do not slow down or other measures, will rear-end collision take place at short notice, send sound and light alarm, cause that human pilot notes, take measures to avoid accident to take place.To overcome the deficiencies in the prior art.
The technical measures that the utility model is taked are: a kind of anti-collision warning device based on visual analysis, comprise microprocessor unit, vision sensor, audible alarm unit, signal gathering unit and display unit is characterized in that: microprocessor unit respectively with vision sensor, audible alarm unit, signal gathering unit and display unit.
Microprocessor unit links to each other with vision sensor by the CAN bus.
Good effect of the present utility model is: the vision sensor on the device can be monitored the vehicle in the place ahead at any time, by certain algorithm computation spacing, calculating with the time that bumps of present speed and front vehicles and by display unit with green, yellow, red three kinds of colors are reminded the present harmful grade of user, when the collision the scope of time in safety in the time, display system shows green, when collision time is lower than 1 second, display system prompting yellow signal, when the time shortens to and is enough to cause when collision, send the conflict alert signal, display blinking red lamp, loudspeaker send the rapid sound that pipes, the prompting human pilot is taken action, with the generation of avoiding colliding.The actual travel speed of signal gathering unit collection vehicle, whether signal such as brake, obtain whether the danger of knocking into the back is arranged by computing with front truck, when having knock into the back dangerous, human pilot is not still taked brake, mean that collision is about to take place, system will sound a warning to human pilot by the acousto-optic different modes, impel human pilot in time to take measures, and avoid the generation of rear-end collision.

Described vision sensor 1, be responsible for road ahead information is carried out image acquisition, and carry out graphical analysis, find the vehicle that travels in the place ahead, and calculate the spacing of Ben Che and front vehicles, and communicate by letter signals such as the speed of acquisition vehicle, brake with microprocessor unit 2 by the CAN bus according to certain computing method, carry out analysis-by-synthesis, draw whether to exist and pass to microprocessor unit 2 with the dangerous of preceding vehicle collision and by the CAN bus.
As shown in Figure 2, described microprocessor unit 2 is by various signals such as signal gathering unit 5 collection vehicle speed, brakes.And link to each other with vision sensor 1 by the CAN bus, information such as the speed of vehicle, brake are delivered to vision sensor 1, and obtain and the risk of collision of preceding vehicle from vision sensor 1.
Described audible alarm unit 3 is subjected to microprocessor unit 2 controls, sends the different sounds, represents various warning, reminds the vehicle drive personnel to note.
As shown in Figure 3, described signal gathering unit 5, directly be connected with the circuit of automobile, detect the speed pulse signal of vehicle, obtaining the speed of vehicle through microprocessor unit 2 computings, is that the signal that can use of microprocessor unit 2 is for microprocessor unit 2 uses simultaneously with signal transition such as the brake of vehicle, headlights.
As shown in Figure 4, described display unit 4 is a kind of display circuits, is subjected to microprocessor unit 2 controls, shows various information, comprises information such as warning level, fault, spacing.
Claims (2)
