Abstract
The utility model discloses a vehicle-mounted overspeed warning device which comprises a single-chip microcomputer, a camera, an image capture card, a rotating speed sensor, a scan driver, a liquid crystal display (LCD), the warning device and a power module, wherein the camera is used for capturing images in real time and storing the images in an internal memory of the image capture card, image information is further extracted and analyzed by the single-chip microcomputer, the rotating speed sensor fixed on a wheel is used for acquiring rotating speed of the wheel in real time and sending acquired information to the single-chip microcomputer for processing, the real-time speed is displayed on the LCD by starting the scan driver, the warning device is triggered by the single-chip microcomputer to send an alarm when the rotating speed reaches to limiting speed of the road section, and the power module provides power for the whole detector. The vehicle-mounted overspeed warning device is capable of well preventing the overspeed phenomenon by sending the overspeed alarm to a driver in a vehicle, and measuring and displaying the speed, and has the advantages of being high in reliability, economical, and the like.
Description
Technical field
The utility model relates to a kind of annunciator, specifically a kind of Vehicular Dver speed alarm.
Background technology
Along with the high speed development of national economy, China's Automobile Transportation industry has obtained fast development, and meanwhile, for various reasons, overspeed of vehicle causes traffic accident to take place frequently, and has brought huge loss for people's life and property.Safe driving becomes the focus that everybody pays close attention to, and wherein the design of Vehicular Dver speed alarm and demand seem extremely important and urgent.
At present, people are provided with monitoring camera on road, the a series of device such as electronic police, speed to vehicle is monitored, yet these devices are all from automobile external, automobile speed to be monitored, the moving velocity information that chaufeur can only obtain by the moving velocity table in operator's compartment at driving procedure, but the information warning that can not obtain exceeding the speed limit.For this situation, design a kind of vehicle-mounted detection and warning, response is fast, reliability is high, comparatively economic automobile overspeed alarm device is the problem that the contriver will solve.
Summary of the invention
For the defective that exists in prior art, the purpose of this utility model is to provide Vehicular Dver speed alarm, solves the deficiency that existing overspeed of vehicle fixed point detects.
The technical scheme that its technical matters that solves the utility model adopts is: Vehicular Dver speed alarm comprises micro controller system, camera, image pick-up card, tachogen, scanner driver, LCD display, warning device and power module.
When the utility model used, when automobile starting, the outer speed-limit warning identification image of camera Real-time Collection car was stored in the internal memory of image pick-up card; Again by micro controller system further extract, analysis image information, the speed limit identification information of speed limit signboard outer according to captured car and remove stated-speed sign board information is determined the limited speed in highway section, the current place of car; Be fixed on the rotating speed of the tachogen Real-time Collection wheel on wheel, and this information sent into micro controller system process, start scanner driver the real-time speed of a motor vehicle is shown on LCD display; When actual vehicle speed reached the limited speed in this highway section, micro controller system trigger alarm device sent alarm sound, prompting chaufeur hypervelocity.Power module provides power supply for whole detector.
The beneficial effects of the utility model are: utilize the collaborative works such as micro controller system, camera, image pick-up card, tachogen, realized the overspeed of vehicle detection.This utility model is by carrying out overspeed alarm to chaufeur in car, phenomenon that can well the preventing car hypervelocity, but also can measure and the size of display speed has that reliability is high, economic dispatch advantage comparatively.
Description of drawings
Fig. 1 is the utility model principle assumption diagram.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used for explanation the utility model and be not used in restriction scope of the present utility model.Should be understood that in addition the relevant technical staff in the field makes various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims restricted portion equally.
Referring to Fig. 1, Vehicular Dver speed alarm comprises power module (1), warning device (2), scanner driver (3), LCD display (4), micro controller system (5), camera (6), image pick-up card (7), tachogen (8), and power module (1) connects all needs supply module.
When the utility model uses, when automobile starting, camera (6) real-time image acquisition, be stored in the internal memory of image pick-up card (7), again by the further extraction of micro controller system (5), analysis image information, speed on stated-speed sign board outer according to captured car identifies frame and removes stated-speed sign information, determines the limited speed in highway section, the current place of car; Be fixed on the rotating speed of tachogen (8) the Real-time Collection wheel on wheel, and this information is sent into micro controller system (5) process, starting scanner driver (3) upward shows the real-time speed of a motor vehicle at LCD display (4), when rotary speed information reaches the limited speed in this highway section, micro controller system trigger alarm device (2) sends alarm sound, prompting chaufeur hypervelocity.Power module (1) provides power supply for whole detector.
