Abstract
The invention discloses an ultrasonic ranging backing-up reminder comprising a single-chip microcomputer, an ultrasonic transmitting module, an ultrasonic receiving module, a video acquisition module, a display module, a speech circuit, and an alarm circuit. The input end of every one of the ultrasonic transmitting module, the display module, the speech module and the alarm circuit is connected with the single-chip microcomputer. The output ends of both the ultrasonic receiving module and the video acquisition module are connected with the single-chip microcomputer. The ultrasonic ranging backing-up reminder further comprises a backing-up bake switch. The input end of the backing-up bake switch is connected with the single-chip microcomputer. The video acquisition module feeds an image of rear view back to an LED display screen. The speech circuit plays a distance between the back of a car and an obstacle in real time so as to more directly remind a driver. When the distance exceeds a safety value, the single-chip microcomputer shuts off the backing-up bake switch to stop the car from backing up, and life safety of the driver and passengers inside is further ensured.
Description
Technical field
The present invention relates to supersonic sounding field, be specifically related to a kind of supersonic sounding reversing alarm set.
Background technology
Current, after adopting ultrasonic ranging substantially, the reversing prompting field of vehicle embodies by forms such as certain sound, numeral demonstration or signal flickers, and numeral demonstration and the audible alarm with different distance belong to main way.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and technical matters to be solved is for providing a kind of supersonic sounding reversing alarm set.
To achieve these goals, the present invention adopts following technical scheme:
A kind of supersonic sounding reversing alarm set, comprise micro controller system, super sonic sending module, super sonic receiver module, video acquisition module, display module, sound circuit and warning circuit, the input end of described super sonic sending module, display module, sound circuit and warning circuit is connected with described micro controller system, the mouth of described super sonic receiver module, video acquisition module is connected with described micro controller system, also comprise reversing brake switch, the input end of described reversing brake switch is connected with described micro controller system.
Further, described supersonic sounding reversing alarm set also comprises the IR evading obstacle sensors being arranged on after car.
Further, described micro controller system is MC9S12XS128MAA micro controller system.
Further, described micro controller system is MC68HC908GP32 micro controller system.
Further, described display module is LED display module.
Further, described ultrasound measurement module is HC-SR04 type ultrasonic distance measuring module.
The invention has the beneficial effects as follows: adopt ultrasonic distance measuring module and micro controller system to coordinate to implement the distance of rear end and obstacle of checking vehicles, and the image after the car that distance value and video acquisition module are collected is presented on display module, simultaneously, sound circuit is play distance value after car in real time, chaufeur is according to this distance value and in conjunction with image after car, can well judge the position of vehicle distances obstacle and the scene situation after car, be convenient to driver safety reversing; When the distance after car has surpassed safety value, described micro controller system will be closed reversing brake switch, and then stop vehicle reversing, further ensure chaufeur and passenger inside the vehicle's life security.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is elaborated:
Fig. 1 is electrical block diagram of the present invention.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
As shown in Figure 1, a kind of supersonic sounding reversing alarm set, comprise micro controller system, super sonic sending module, super sonic receiver module, video acquisition module, display module, sound circuit and warning circuit, the input end of described super sonic sending module, display module, sound circuit and warning circuit is connected with described micro controller system, and the mouth of described super sonic receiver module, video acquisition module is connected with described micro controller system; Also comprise reversing brake switch, the input end of described reversing brake switch is connected with described micro controller system.Described micro controller system is MC9S12XS128MAA micro controller system or MC68HC908GP32 micro controller system, and described display module is LED display module, and described ultrasound measurement module is HC-SR04 type ultrasonic distance measuring module.
Single-chip Controlling super sonic sending module and super sonic receiver module sending and receiving echo, and according to the hypracoustic transmission time, calculate the distance of rear vehicle end and obstacle, and this distance is presented in LED display, video acquisition module also by the image feedback after car in LED display, LED display is contained in below the dead ahead front windshield of chaufeur, is beneficial to observation.Sound circuit is play the distance value of rear vehicle end and obstacle in real time, more directly reminds chaufeur.Simultaneously, the distance value that micro controller system obtains according to test produces respectively the impulse singla of the different frequency that represents distance to warning circuit, after warning circuit amplifies this impulse singla, respectively by buzzer phone and light emitting diode prompting backing distance, different distance section produces different buzzings and luminescence feature.In the time of within the scope of obstruction and vehicle distances to 1.2 meter, warning circuit is started working, and sends desultory chimes of doom, more and more nearer along with distance, the interval of chimes of doom is shorter, in the time that distance approaches safety distance, there is continuous sound in buzzer phone, can not move backward, in order to avoid collision to show again.In the time that distance arrives safety distance, micro controller system is closed reversing brake switch, forces to stop chaufeur and continues reversing, further ensures chaufeur, passenger inside the vehicle and car pedestrian's etc. the security of the lives and property.
Further, described supersonic sounding reversing alarm set also comprises the IR evading obstacle sensors being arranged on after car.IR evading obstacle sensors has played the another kind of detection mode that approaches obstacle, once ultrasonic transceiver circuit lost efficacy, can combine to remind by IR evading obstacle sensors driver with camera, thereby prevents collision.
Above-described embodiment is just the content that allows one of ordinary skilled in the art can understand this law labyrinth and implements according to this for technical conceive of the present invention and feature being described, its objective is, can not limit the scope of the invention with this.Every equivalent variation or modification that according to the present invention, the essence of content has been done, all should be encompassed in protection scope of the present invention.
