Abstract
Of the invention and a kind of load-carrying motor vehicle superelevation siren, belongs to vehicle driving safety facility.Set CCD to carry out detection collection in main section, using plug-in type image acquisition board and its drive software the transmission speed of pci bus and the performance of processor can be made full use of to carry out real-time monitoring surface without other specialised hardwares.3 points of fixed point detections are carried out with reference to laser range finder, average is used as final measured value；Picture altitude combination ranging is collected, analysis calculating is carried out.The advantage of the invention is that：Motor vehicle limit for height road surface can be ensured（Provide limit for height, bridge, culvert etc.）Driving safety, in the conscientious real-time monitoring in main section, accurately to motor vehicle, whether superelevation carries out discriminatory analysis, so as to send alarm early warning.Potential safety hazard of the driver caused by absent minded, tired, weather influence etc. can be excluded, it is ensured that driver's person property and communal facility safety.
Description
Technical field
The invention belongs to vehicle driving safety facility, a kind of vehicle super-high warning device is referred in particular to.
Background technology
As highway bridge traffic infrastructure storage is continuously increased, there is nonstandard behavior in user, while overload of vehicle and natural cause will also result in influence and endanger, in order to ensure people life property safety, it is necessary to limit for tonnage.In the evolution in city, in order to solve traffic congestion, occur in that many Urban Bridges and viaduct, various regions, which are accordingly also increased, is provided with height-limiting gantry to carry out control to traffic before many bridges and viaduct, at present, when loading motor vehicle passes through limit for height road conditions, generally judge passability by driver experience, and in actual travel, due to judgment bias, low visibility, the problems such as fatigue driving, often there is driver's erroneous judgement problem, even alarming sign is not seen, so that superelevation loading motor vehicle error row rolls existing collision accident away from, there are major safety risks.
The content of the invention
The present invention provides a kind of load-carrying motor vehicle superelevation siren, to solve to judge that passability causes the problem of judgment bias, low visibility, fatigue driving by driver experience.
The technical scheme is that：Set CCD to carry out detection collection in main section, using plug-in type image acquisition board and its drive software the transmission speed of pci bus and the performance of processor can be made full use of to carry out real-time monitoring surface without other specialised hardwares.3 points of fixed point detections are carried out with reference to laser range finder, average is used as final measured value.
Image capturing system uses black white image, and black white image system has higher precision and faster frame rate compared with color system, therefore most of application schemes all adopt plate using black and white camera and slotting people's formula artwork master.The size of black white image frame three times at least smaller than coloured image are more suitable for the high image capturing system of high accuracy, real-time.
Picture altitude combination ranging is collected, analysis calculating is carried out.When result of calculation exceedes threshold value, by signal transmitting system, car alarm is transferred to, is reminded.Brakes can also be combined and carry out forced deceleration.
Computational methods：Laser range finder launches height of the laser acquisition position far from ground for H, and the distance of laser acquisition and goods is M, then vehicle-mounted height is h, and vehicle-mounted height and limit are led to and are highly compared, more than the then car alarm alarm of the logical height of limit, less than then safety.
The advantage of the invention is that：Motor vehicle limit for height road surface can be ensured（Provide limit for height, bridge, culvert etc.）Driving safety, in the conscientious real-time monitoring in main section, accurately to motor vehicle, whether superelevation carries out discriminatory analysis, so as to send alarm early warning.Potential safety hazard of the driver caused by absent minded, tired, weather influence etc. can be excluded, it is ensured that driver's person property and communal facility safety.
