Abstract
The utility model discloses a car monitoring device that backs a car that moves ahead based on embedded linux adopts displacement sensor to detect the automobile and moves ahead or back a car, turns into the signal of telecommunication with the signal that detects, sends embedded system to, and embedded system handles data, makes and judges the back, and the control signal switching circuit switches over with the supervisory circuits that backs a car the supervisory circuits that moves ahead. If the car is in the state of moving ahead, embedded system then received the signal that comes from the transmission of front truck supervisory circuits, if the automobile is in the state of backing a car, embedded system then received the signal that comes from the supervisory circuits transmission of backing a car, and the signal that embedded system accepted all can show through liquid crystal display and LED pilot lamp. The utility model discloses it provides safe vehicle distance's reference information can the wide application to move ahead to park in the car for the driver with the in -process of backing a car.
Description
Technical field
The utility model relates to embedded Linux technology field and sensor detecting field, is specially a kind of automobile front driving reversing monitoring device based on built-in Linux.
Background technology
Along with automobile popularizing rapidly in China, increasing automotive safety problem receives the concern of people, no matter be to the strict demand of taking driving test or the strict regulations to traffic regulation, knock into the back or the still generation again and again of reversing accident, safety problem is never improved.Due to chaufeur, field range is limited when driving, advance travel stop time can not judge front-and-rear vehicle distance from and knock into the back; In reversing process, the situation after car can only be observed by back mirror, and particularly some dead angles cannot observe, in case of emergency can not react in time, accident rate increases greatly.In order to solve the generation of the accident caused due to the limitation in the visual field in this reversing process that moves ahead, the present utility model devise a kind of system stability, can the real time monitoring apparatus based on built-in Linux of display automobile front and back scene and distance.
Utility model content
The utility model object is to provide a kind of automobile front driving reversing monitoring device based on built-in Linux, has solved the difficult problem in prior art reliability and safety.
1. in order to achieve the above object, technical solution adopted in the utility model is: the automobile front driving reversing monitoring device of built-in Linux, it is characterized in that comprising: the astern direction that moves ahead testing circuit, the supervisory circuit that moves ahead, reversing supervisory circuit, LED light, LCDs, signal switching circuit, circuit is switched to move ahead supervisory circuit or reversing supervisory circuit by the control signal that wherein signal switching circuit can send according to embedded system.
The astern direction that moves ahead testing circuit is characterized in that: core is displacement pickup, can judge the running state residing for automobile.
The supervisory circuit that moves ahead is characterized in that: mainly comprise COMS camera and ultrasonic transduter, is used for respectively gathering vehicle front image and calculating the distance with the nearest obstacle in front.
Reversing supervisory circuit is characterized in that: mainly comprise COMS camera and ultrasonic transduter, is used for respectively gathering vehicle front image and calculating the distance with the nearest obstacle in rear.
LED light and LCDs are execution parts, and embedded Linux system receives the video information of supervisory circuit and the range information of detection can be shown by (SuSE) Linux OS after treatment on LCDs; Distance between automobile and obstacle reach setting value after embedded Linux system also can control LED light and become blink states.
The beneficial effects of the utility model comprise:
1. move ahead supervisory circuit and reversing supervisory circuit lays respectively at the front and back position of automobile, the dead angle of comprehensive covering automobile, increase the field range of navigating mate, also car and the distance recently between obstacle is calculated accurately, and in the distance range of setting, warned by LED light flicker.
2. embedded Linux system can by the range information of video information and concrete automobile and obstacle by camera and ultrasonic transduter collection, directly show inside the interface of operating system, watch more directly perceived, and software and hardware can cutting, dependable performance, stable, volume is little, low in energy consumption.
Accompanying drawing explanation
Fig. 1 is the utility model mechanical schematic diagram.
Wherein, 1 boot compartment, 2 reversing supervisory circuits, 3 machinery spaces, 4 move ahead control monitor unit, 5 bearing circle, 6 LCDs and LED light.
Fig. 2 is the utility model functional-block diagram.
Wherein, 1 moves ahead astern direction testing circuit, 2ARM9/Linux system, 3 signal switching circuits, and 4 move ahead supervisory circuit, 5 reversing supervisory circuits, 6LED indicator lamp, 7 LCDs.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with Fig. 2, setting forth the utility model further.
Detailed description of the invention is as follows:
As shown in Figure 2, when automobile is in running state, the Signal transmissions that the astern direction that moves ahead testing circuit 1 is detected by inner displacement pickup carries out data analysis judgement in ARM9/Linux system 2.If detect, automobile is in forward traveling, ARM9/Linux system 2 sends control signal to signal switching circuit 3, signal switching circuit 3 supervisory circuit 4 that will move ahead is connected with to ARM9/Linux system 2, the supervisory circuit 4 that moves ahead is transferred to ARM9/Linux system 2 by inner CMOS camera and ultrasonic transduter Information Monitoring, ARM9/Linux system 2 is controlled to export and video image and the spacing of calculating and the range information of nearest obstacle is shown on linux system by LCDs 7, once the distance calculated is in the scope of setting, LED light 6 will be glimmered and be sent warning, if detect, automobile is in state of rolling backward, ARM9/Linux system 2 sends control signal to signal switching circuit 3, reversing supervisory circuit 5 is connected with to ARM9/Linux system 2 by signal switching circuit 3, reversing supervisory circuit 5 is transferred to ARM9/Linux system 2 by inner CMOS camera and ultrasonic transduter Information Monitoring, ARM9/Linux system 2 is controlled to export and video image and the spacing of calculating and the range information of nearest obstacle is shown on linux system by LCDs 7, once the distance calculated is in the scope of setting, LED light 6 will be glimmered and be sent warning, invention increases the visual field of steerman, considerably reduce accident rate.
The above, be case study on implementation of the present utility model, all should be encompassed in the utility model.
