Accompanying drawing explanation
Describe these and other aspect of the present utility model in further detail now with reference to appended accompanying drawing, it is depicted as currently preferred embodiment of the present utility model.Wherein:
Fig. 1 is the fundamental diagram that the utility model highway keeps the warning system of traffic safety spacing.
In figure: 1a, infrared distance sensor; 1b, infrared distance sensor; 2, control module; 3, alarm unit; 31, light warning circuit; 32, voice alarm circuit; 4, liquid crystal display; 5, driving recording video processing unit; 61, front-facing camera; 62, post-positioned pick-up head; 7, external data storage; 8a, drive recorder; 8b, drive recorder.
Embodiment
Below in conjunction with accompanying drawing and instantiation, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
Embodiment one:
As shown in Figure 1, a kind of highway keeps the warning system of traffic safety spacing, comprise two groups of infrared distance sensors (1a, 1b), infrared distance sensor 1a be arranged on automotive front end and its tube-launched laser towards vehicle front, infrared distance sensor 1b be arranged on automobile rear end and its tube-launched laser towards rear view of vehicle.So, when vehicle is about to knock into the back or knocked into the back, can implement to learn, so that follow-up prompting driver.
Two groups of infrared distance sensors all couple control module 2, and control module 2 is coupled with alarm unit 3.
So, the infrared distance sensor of the present embodiment utilizes infrared signal to run into the also different principle of the intensity of the difference reflection of obstacle distance, carries out the detection of barrier distance.Infrared distance sensor has a pair infrared signal launching and receiving diode, power valve launches the infrared signal of characteristic frequency, receiving tube receives the infrared signal of this frequency, when infrared detection side is to when running into barrier, infrared signal reflects received pipe and receives, after process, turn back to control module 2 by digital sensor interface, control module 2 can utilize infrared return signal to identify the change of surrounding environment.Namely the distance between periphery and automobile.
Indiffusion principle when what specifically it utilized is infrared ray propagation, because infrared ray refractive index when passing through other material is very little, so the stadimeter of long distance all can consider infrared ray, and ultrared propagation needs the time, encounter reverberation and be reflected back when infrared ray sends from stadimeter and be accepted to, again according to infrared ray from being issued to time of being accepted to and ultrared velocity of propagation just can calculate distance, ultrared principle of work: the phase shift utilizing the infrared ray of high frequency modulated to come and go generation on testing distance is extrapolated light beam degree and got over time △ t, thus obtain distance D according to D=C △ t/2.
Therefore, be to calculate the distance between periphery barrier and automobile immediately by infrared distance sensor with coordinating of the single-chip microcomputer as control module 2.If the distance between barrier and automobile is less than default minor increment numerical value, then Single-chip Controlling alarm unit 3 carries out Realtime Alerts, prevents traffic hazard or scratch automobile.
Preferably, alarm unit 3 comprises light warning circuit 31 and voice alarm circuit 32; Light warning circuit 31 and voice alarm circuit 32 all couple with control module 2.So, by cooperatively interacting of light warning circuit 31 and voice alarm circuit 32, the attention of driver can be caused immediately, prevent the generation of accident further.
Further, light warning circuit 31 comprises two groups of alarm lamps corresponding respectively with infrared distance sensor, and alarm lamp controls to open and close by control module 2.So, two groups of group alarm pilot lamp can respectively the side of corresponding automobile and barrier too close to time carry out alarm, be convenient to the position that driver distinguishes dangerous obstacles, evade in time.
Certainly, the present embodiment by presetting voice broadcast information, can also carry out difference to the dangerous obstacles from forward and backward side and reporting to the police respectively.Separately carry, because voice broadcast circuit is the ripe prior art in conjunction with chipspeech, therefore its internal circuit structure does not do necessary restriction.
Moreover, the control module of the present embodiment is after receiving the distance signal exported from each infrared distance sensor, carry out numerical monitor by the liquid crystal display 4 coupled with it, be convenient to the actual range that driver gets information about other vehicles or barrier and this car.
In addition, the present embodiment is provided with front-facing camera 61 at vehicle front further, monitors vehicle front event; Be provided with post-positioned pick-up head 62 in rear vehicle end, monitor that rear view of vehicle event front-facing camera 61 and post-positioned pick-up head 62 all couple driving recording video processing unit 5, driving recording video processing unit 5 has external data storage 7 by control module communication.So, the image information of supervision can be transferred to control module by front-facing camera 61 and post-positioned pick-up head 62 in real time, and image information can be delivered to liquid crystal display 4 and play in real time by control module on the one hand, makes driving safer; Image information can be stored in external data memory on the other hand, be convenient to investigate and collect evidence.
Embodiment two:
As shown in Figure 2, the difference of the present embodiment and embodiment one is only, only installs drive recorder (8a, 8b) at vehicle front and back ends.So, drive recorder can provide the real time monitoring to vehicle front and back ends, so that the later stage investigates and collects evidence, but is not play synchronous the image information monitored by liquid crystal display 4.
Certainly, the present embodiment does not get rid of the drive recorder with real-time playing function.
