Embodiment
In order to arrive the have an accident purpose of moment image scene of registration of vehicle, the utility model combines two kinds of technology: digital image shooting technology and acceleration sensing technology.
The digital image shooting technology is the technology that photo-sensitive cells such as a kind of CCD of utilization or CMOS change optical imagery digital signal and handle and store.General digital image shooting device has the optical imagery unit, image sensing cell, image storage unit, several sections such as picture system controller, its operation principle is summarized as follows: the optical imagery unit can clearly be imaged on the optical imagery of the outside scenery of certain limit on the image sensing cell, image sensing cell is a two-dimensional array that is made of photo-sensitive cells such as CCD or CMOS, photo-sensitive cell changes the power of every bit light into the signal of telecommunication, the picture system controller with these signals of telecommunication and corresponding coordinate through handling the digital document that is converted into specific format, then with these file storage in image storage unit.Utilize these files, can further show or export the image that is filmed by computer or other instruments.Start digital image shooting system and only take and need import a control signal by the picture system controller, general digital image shooting system is triggered by the people by a button.
The acceleration sensing technology is the technology that a kind of sense object movement velocity changes, and can change object linear movement acceleration magnitude into the signal of telecommunication by acceleration transducer.This technology is used in automobile widely, and for example the startup of automobile air bag when bumping realizes by the change of acceleration transducer monitoring car speed.
The utility model proposes a kind of digital image shooting system that is triggered by acceleration signal in conjunction with digital image shooting technology and these two kinds of technology of acceleration sensing technology.Its basic principle is as follows: at first, utilize acceleration transducer to change the acceleration of motion size of automobile into the signal of telecommunication, be sent in the control-signals generator after the amplification of the signal of telecommunication by signal amplifier then, control-signals generator can compare input signal and preset threshold, when the accekeration that records surpasses preset threshold, control-signals generator produces a control signal and is input in the picture system controller, the picture system controller starts digital image shooting system and carries out image taking, and the image of shooting is stored in image storage unit so that query display.
With reference to the accompanying drawings 1, the utility model comprises digital image shooting device and acceleration sensing device, wherein the optical imagery unit of digital image shooting device and image sensing cell will be aimed at the direction that needs shooting, and acceleration transducer need be fixed on the car body and the hand designations on degree of the will speed up transducer is aimed at the acceleration direction that needs monitoring; After the system start-up, acceleration sensing system is monitored the velocity variations of automobile in real time, when automobile runs into situation by brake hard, the pickup that acceleration transducer is sensed has surpassed preset threshold, control-signals generator is sent a signal triggering digital image shooting system and is taken, the image of taking can be static also can be dynamic, then information such as the image of Pai Sheing, shooting time and shooting brief acceleration value are saved in the image storage unit.In the time need reading relevant image to the emergency analysis that automobile takes place, just can obtain as long as image storage unit linked to each other with the relevant calculation machine equipment, also can show by the display device of equipping on the automobile.Utilize image storage unit can repeat erasable characteristics, can suitably set lower acceleration rate threshold (threshold value that this threshold value is opened well below air bag) and guarantee that each emergency can both be noted down reliably.
With reference to the accompanying drawings 2, the weak electric signal that acceleration transducer 1 produces amplifies by the signal amplifier that operational amplifier 2 constitutes, obtain one 0 voltage signal to 5V, by the analog to digital converter ADC0809 in the control-signals generator 3 analog quantity is converted to digital quantity then, this digital quantity is sent among the single-chip microcomputer 89C51 by data/address bus and handles then, calculating and differentiation by singlechip CPU, when accekeration surpasses the limit of setting, produce a signal by singlechip CPU by port P1.2, this signal outputs in the picture system controller of digital image shooting device by the isolation of optocoupler PC827.The model of acceleration transducer 1 is ADXL311EB in the present embodiment, and it is the operational amplifier of LM2904 that operational amplifier 2 adopts model.
