Multiple positional informations of multiple test points are sent to control centre in the 3 continuous obstacle examination halls for determining place information acquisition module
Server 9；On the other hand, examining in the continuous obstacle examination hall of entrance that GPS receiver 3 determines on-vehicle information acquisition module
The motion outline and position course information of car 14 are sent to control centre's server 9.
Further, it is multiple in the continuous obstacle examination hall that control centre's server 9 will be sent by GPS receiver 3
Multiple positional informations of test point and Kao Che 14 motion outline and position course information are sent to vehicle-mounted judge computer 8,
It is vehicle-mounted judge computer 8 according to above-mentioned multiple positional informations, examine the motion outline of car 14, examine car 14 position course information and
The safe information that data acquisition device is sent, speed information and gear information, judge and enter examining in continuous obstacle examination hall
Whether car 14 passes through when bypassing cake, meets driver safety driving demand.
Wherein, continuous obstacle examinations evaluation result is mainly：Navigated according to the position for the motion outline and Kao Che 14 for examining car 14
Judged to information and multiple test points of the setting in continuous obstacle examination hall, if examining car 14 in correct position course information
It is interior, examine some in the motion outline of car 14 select it is overlapping with the test point on cake, it is determined that this examines car 14 not by current test；
Ruo Kaoche 14 in correct position course information, examine that the motion outline of car 14 includes select not with the test point weight on cake
It is folded, and by safe information, speed information and gear information, determine that the driving situation of examinee meets driver safety driving
It is required that, it is determined that this examines car 14 by current test.
Further, it is vehicle-mounted judge computer 8 will currently examine the examination evaluation result of car 14 by wireless network send to

Based on identical inventive concept, the embodiment of the present invention additionally provides a kind of continuous obstacle examinations detection method, due to
The principle that this method solves technical problem is similar to a kind of continuous obstacle examinations detection means, therefore the implementation of this method can be joined
See the implementation of device, repeat part and repeat no more.
Fig. 3 is a kind of continuous obstacle examinations detection provided in an embodiment of the present invention, as shown in figure 3, this method mainly includes
Following steps：
Step 301, by being arranged on the vector sensor and positioning antenna examined on car, it is determined that being arranged in continuous obstacle examination hall
Multiple positional informations of test point on multiple cakes；
Step 302, the base station gps antenna being arranged in the continuous obstacle examination hall, the vector sensor and institute are passed through
Positioning antenna is stated, it is determined that into when examining car described in the continuous obstacle examination hall and bypassing multiple cakes, the car of examining
Motion outline and position course information；
Step 303, according to multiple positional informations, the motion outline and the position course information, judge described in examine
Whether car bypasses multiple cakes according to this.
It should be noted that in above-mentioned steps, it is necessary to according to step 301, the order of step 302 and step 303 is performed,
And step 301, the order between step 302 and step 303 can not overturn.
Wherein, in step 301 and step 302, it is determined that multiple positional informations of the continuous multiple test points in obstacle examination hall and really
Surely enter the motion outline for examining car and position course information in continuous obstacle examination hall, employ RTK technologies.Both are different
It is that in step 301, it is fixed to be arranged on the vector sensor examined on car, i.e., as base station, and position antenna in continuous obstacle
Moved in examination hall, i.e., as rover station；In step 302, the base station gps antenna being arranged in continuous obstacle examination hall is fixed not
It is dynamic, i.e., as base station, and the vector sensor and positioning antenna examined on car are arranged on, move, that is, swear with the movement for examining car
Amount antenna and positioning antenna are used as rover station simultaneously.
Specifically, in step 301, it is motionless to be arranged on the vector sensor examined on car, that is, examines car and fix and be parked in continuous obstacle
In examination hall, and another positioning antenna exists the positioning antenna from examined the test point position lifted down on car, determine as needed
Moved in continuous obstacle examination hall, so as to determine multiple positions letter of the multiple test points set in continuous obstacle examination hall according to this
Breath.
In step 302, the base station gps antenna being arranged in continuous obstacle examination hall is fixed, i.e. base station GPS
Antenna is fixedly installed in continuous obstacle examination hall, and examines the vector sensor that is set on car and positioning antenna can be with the movement for examining car
And moved in continuous obstacle examination hall, by examining the movement of car, vector sensor and positioning antenna are driven in continuous obstacle examination hall
It is mobile.Specifically, the base station gps antenna 7 being arranged in continuous obstacle examination hall receives GPS positioning satellite hair according to setting time
The framing signal that GPS positioning satellite is launched is sent to reference GPS receiver 6 by the framing signal penetrated, base station gps antenna 7,
Reference GPS receiver 6 determines differential correcting value according to the framing signal and base station current location information that receive,
And by the differential correcting value by reference GPS receiver 6, the radio station 4 being arranged in continuous obstacle examination hall and be arranged on and examine car
Radio antenna 5 on 14 is sent to GPS receiver 3, and car 14 is examined because vector sensor 1 is separately positioned on positioning antenna 2
Headstock and the tailstock, the positioning of vector sensor 1 that vector sensor 1 and positioning antenna 2 launch the GPS positioning satellite received respectively
The framing signal of signal and positioning antenna 2 is sent to GPS receiver 3, GPS receiver 3 according to differential correcting value and
Position the framing signal of antenna 2 and the framing signal of vector sensor 1 determines the position of vector sensor 1 and positioning antenna 2 respectively
Confidence ceases, that is, the positional information of the headstock and the tailstock of examining car is determined, according to the positional information of headstock and the tailstock, it may be determined that go out
Examine the contour shape of car.Further, moved always in continuous obstacle examination hall due to examining car, if the reception GPS of setting determines
The time interval of the framing signal of position satellite launch is smaller, then can determine and examine according to the motion outline for examining car of determination
