Embodiment:
Below in conjunction with accompanying drawing the present invention is done further explanation:
A kind of radar for backing car self-stop device; Constitute by ultrasonic radar detection agency, object distance set mechanism and parking topworks; As shown in fig. 1; The ultrasonic radar detection agency comprises that ultrasonic transmit circuit 4 is used to launch ultrasound wave, ultrasound wave receiving circuit 5 is used to receive ultrasound wave, signal amplification circuit 6, and DC control circuit 7, voice warning circuit 8 are used to point out distance and the single-chip microcomputer 1 between barrier and the car to be used to control total system.
The object distance set mechanism is object distance setting device 2, is used to preestablish the distance between barrier and the car.
Parking topworks is an electromagnetic brake device 9, is used to carry out the stop sign that single-chip microcomputer 1 sends.
Object distance setting device 2 connects single-chip microcomputer 1 and ultrasonic generator 3 respectively; Ultrasonic generator 3 links to each other with ultrasonic transmit circuit 4; Ultrasound wave receiving circuit 5 connects signal amplification circuit 6; Signal amplification circuit 6 connects DC control circuit 7, and DC control circuit 7 connects voice warning circuit 8 and single-chip microcomputer 1 respectively; Single-chip microcomputer 1 also connects voice warning circuit 8 and electromagnetic brake device 9.
This radar for backing car self-stop device also comprises power supply 10, and power supply 10 connects ultrasonic generator 3, signal amplification circuit 6 and single-chip microcomputer 1 respectively, is ultrasonic generator 3, signal amplification circuit 6 and single-chip microcomputer 1 power supply.
The working power 10 of said radar for backing car self-stop device is parallelly connected with automobile power source.
The principle of work of radar for backing car self-stop device of the present invention is following:
The present invention in use, the whole radar for backing car self-stop device of single-chip microcomputer 1 control system, the pre-set before use distance of object distance setting device 2, and being sent in the single-chip microcomputer 1; Ultrasonic generator 3, ultrasonic transmit circuit 4, ultrasound wave receiving circuit 5 use as transmitting and receiving integrative ultrasonic ripple probe; Adopt single-chip microcomputer 1 control ultrasonic transmit circuit 4 to send ultrasound wave, ultrasonic waves transmitted runs into the barrier reflection, and the ultrasound wave that reflects arrives ultrasound wave receiving circuit 5; Transmitting and receiving the ultrasound wave that reflects that integrative ultrasonic ripple probe will receive sends into signal amplification circuit 6 and amplifies; Behind DC control circuit 7, carry out data processing by single-chip microcomputer 1, send into voice warning circuit 8 then; Display-object obstacle distance and orientation, the distance between voice suggestion explanation target obstacle and the vehicle.At this moment; Object distance setting device 2 judges whether the distance between the vehicle-to-target barrier reaches predefined safe stopping distance; If the distance that detects has reached the safe stopping distance that presets, then notify single-chip microcomputer 1 to send stop sign to electromagnetic brake device 9, carry out the action of stopping; Automobile power source 10 and electromagnetic brake device 9 coils are connected in single-chip microcomputer 1 control; Coil generates an electromagnetic field, and with brake flange generation effect (friction force that is equivalent to bremsbelage and drum and dish), thereby reaches self-stopping purpose.
The present invention proposes a kind of radar for backing car self-stop device; Have the function of distance between instant detection vehicle and the reversing target object, and can carry out voice suggestion, automatic stopping when the distance between the vehicle-to-target barrier reaches predeterminable range; Thereby realize that accurate distance stops; Simple and reasonable, be convenient to the driver and use, be easy to apply.
