Switch, it is not only troublesome in poeration, but also often there is student not know by switch, cause to take an examination unqualified, often causes student's
Discontented and complaint.
It is bothered in view of traditional switch push-botton operation, and there is student often to forget to go by cause to take an examination unqualified etc. bring
Dispute and complaint, occur currently on the market it is contactless detected around Che Yizhou, for example detected whether by infrared sensor
It is easy to cause erroneous judgement when being acted around Che Yizhou, but having infrared object under high temperature environment and around due to infrared detection.
In conclusion existing switch button formula detection is troublesome in poeration, actual use often brings dispute.And it is contactless
Infrared detection easily erroneous judgement and environment-adapting ability is poor.

Property, it is applied to detect around Che Yizhou, solves the problems, such as that existing student is underproof because maloperation switch button causes to judge, and
Solves the problems such as existing environment-adapting ability difference of current non-contact infrared induction and easily erroneous judgement.The present invention is using novel super
Sonic detection improves system stability and applicability.
Description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the signals transmission figure of the present invention.
Specific implementation mode
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case of without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.
A kind of vehicle driver driving path examination of technical ability system is around Che Yizhou detection devices, including is set to motor vehicle
On cab signal comprehensive detection module, and the examination evaluation system that is connect with cab signal comprehensive detection module further includes position
Before the ultrasonic radar that the forward and backward vehicle body of motor vehicle sets up separately probe and ultrasonic radar after pop one's head in, before ultrasonic radar probe and
Pop one's head in after ultrasonic radar and connect with ultrasonic radar controller by electric connection line, the ultrasonic radar controller with
Cab signal comprehensive detection module is connected by LIN buses.
Further, probe includes that two ultrasonic radars being set to before motor vehicle are visited before the ultrasonic radar
Head, two ultrasonic radar probes are installed on the Liang Ge corners of motor vehicle headstock.
Further, probe includes being set to subsequent two ultrasonic radars of motor vehicle to visit after the ultrasonic radar
Head, two ultrasonic radar probes are installed on the Liang Ge corners of motor vehicle tailstock.
Further, ultrasonic radar probe includes ultrasonic wave sending module and ultrasonic wave receiving module.
Further, the ultrasonic radar controller includes AT89C51 microcontrollers.
The installation steps of present device：
The first step：Four ultrasonic radars probe is divided into it is each two front and back, be respectively assembled at two turnings of headstock and
Then ultrasonic radar probe is connected on ultrasonic radar controller by the Liang Ge corners of the tailstock by electric connection line.
Second step：The cab signal comprehensive detection module that ultrasonic radar controller is connect with examination evaluation system passes through
LIN buses connect.
Third walks：When student is around Che Yizhou, front and back ultrasonic radar probe senses that barrier exists, and passes through ultrasound
After the processing of wave radar controller, it will be acted around Che Yizhou and give cab signal comprehensive detection module through LIN bus transfers.
4th step：Cab signal comprehensive detection module judges system according to the signal that ultrasonic radar controller transmits to examination
System output.
Through place actual test, being acted around Che Yizhou using ultrasonic radar detection is had greatly compared to regular tap button
Big operation is promoted, and student need not bend over to go to touch the button manually again, it is only necessary to walk one time around before and after vehicle body, in addition
Compared to infrared induction technology, ultrasonic radar environment-adapting ability is more preferably also more stable, can not only meet different kinds of roads situation,
And there is good adaptability for rainy days, greasy weather and four seasons spring, summer, autumn and winter.
More specifically, wherein：Ultrasonic wave sending module and ultrasonic wave receiving module are integrated in a ultrasonic radar simultaneously
In probe, ultrasonic wave sends and receives processing and is all completed by AT89C51 microcontrollers, will be around vehicle one after completing detection of obstacles
All result informations give cab signal comprehensive detection module by LIN bus transfers.
1, ultrasonic wave sends and receives：There is ultrasonic radar controller to be controlled, sends in real time, when single probe ranging
Between 30ms, four probe cycle the ranging periods be 120ms.When student passes through headstock or the tailstock, ultrasonic radar probe can connect
It receives echo-signal and is transferred to ultrasonic radar controller.
2, judge around Che Yizhou：Ultrasonic radar controller is obtained according to the time relationship of ultrasonic wave transmitting and echo reception
Go out out obstacle distance, and is determined as whether having carried out acting around Che Yizhou.There is short distance echo after sending out wave, is then determined as
Student is around Che Yizhou；If without short distance echo, it is judged to not carrying out acting around Che Yizhou.
3, it is exported around Che Yizhou results：Cab signal comprehensive detection mould will be transferred to around Che Yizhou results by LIN buses
Block is judged for examination evaluation system and is used.
Obviously, described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.Based on this
Embodiment in invention, every other reality obtained by those of ordinary skill in the art without making creative efforts
Example is applied, shall fall within the protection scope of the present invention.
