Description

A kind of system of applying GPS technical checking examination driver field test

Technical field

The utility model relates to a kind of system of applying GPS technical checking examination driver field test.

Background technology

Vehicle driver examination equipment is the equipment of the examinee of application driver's license being examined for public security deparment and traffic police department, is used for checking examinee whether to have qualified driving efficiency.Each examination equipment is all generally to adopt the signals such as photoelectricity, vibration, magnetic to obtain travel condition of vehicle at present, judges whether examinee takes an examination qualified.

The side parking examination project of take is below example, the method of prior art is, on tetra-the stake bars of A, B, C, D that represent four jiaos, garage, shock sensor and photoelectric sensor are installed, by catching vibration signal, judge whether vehicle has lance in examination process, by gathering photosignal between AB, BC, CD, DA, judge the whether outlet of examination vehicle vehicle body.Its defect is gathered exterior light electric signal, is subject to the interference of weather conditions very large.Often there will be at an examination point and because extraneous wind-force is excessive, trigger shock sensor signal, cause judging by accident examinee's grazing stake bar, erroneous judgement examinee takes an examination defective.

Utility model content

Of the present utility model objectthe system that is just to provide a kind of applying GPS technical checking examination driver field test, its accuracy is high, is subject to extraneous weather effect very little, there will not be the problem that erroneous judgement occurs because of weather effect, and installs and uses very convenient.

Of the present utility model technical schemefor: the system of a kind of applying GPS technical checking examination of the utility model driver field test, it comprises: examination vehicle, vehicle-mounted GPS equipment A, B, truck-mounted computer, vehicle radio station equipment, GPS base station equipment, and data radio station;

Described GPS base station equipment receives gps satellite signal; Described data radio station is connected in GPS base station equipment for receiving the differential signal that it sends by communication cable, and is broadcast in test site in the mode of radiowave; Described vehicle radio station and data radio station wireless connections, and by communication cable, be connected with vehicle-mounted GPS equipment A, B, vehicle radio station by the differential signal transmission receiving to vehicle-mounted GPS equipment A, B; Described vehicle-mounted GPS equipment A, B are connected with truck-mounted computer, and the locating information that vehicle-mounted GPS equipment A, B comprehensively itself obtain via satellite combines with the difference information of base station and obtains accurate locating information, and it is passed to truck-mounted computer.

Apply of the present utility model principle of workfor: before examination first according to the judgment criteria of examination project, place, test item place take the mark of this examination project as benchmark is divided into corresponding judge region; Then utilize a kind of hand-held surveying and mapping tool, survey and draw out the sideline in the judge region of each test item, and with this hand-held surveying and mapping tool testing vehicle profile and tire the position with respect to vehicle center, and above-mentioned measurement result is input in advance and in truck-mounted computer, forms map file; In when examination by being arranged on two GPS device A, the B on vehicle, Real-time Collection vehicle location, frequency acquisition is per second to be not less than 4 times, by calculating the relative position of two GPS, obtains direction of traffic, and obtains appearance profile each point and tire loca position; Its appearance profile point of different vehicles is different, according to different automobile types, divides respectively; Finally according to vehicle body and judge region, wheel place, the whether qualified or deduction of points accordingly of real-time judge examinee's examination.

The GPS equipment using due to native system adopts RTK(Real-time kinematic) real time dynamic differential technology, positioning precision is 2mm, even if vehicle foremost maximum error is also less than 1cm, meet country for standard (the GA/T 554-2008 field driving skill examination system for automotive drivers) requirement of examination equipment.

Of the present utility model beneficial effectfor: through comparison test confirmation repeatedly, adopt the utility model in the place examination examination of carrying out, precision is high, examination accurately, and reliable operation, has solved the interior complicated procedures of forming that various optoelectronic devices are installed of examination in the past, has avoided in the past because extraneous weather disturbs the problem that caused erroneous judgement.And easy for installation simple, operate easy to use.

Particularly along with up-to-date Examination Rate's requirement, increased a lot of test items, and some project is used usual photosignal to pass judgment on, use GPS equipment and test item carried out to region division and pass judgment on, can be the job simplification of a lot of complexity.Even if standard is upgraded again later, increased respective item or adjusted Examination Rate, native system only need be adjusted cartographic information in software systems, does not need to increase or transform any hardware device, the expense and the time that have reduced greatly upgrading, can reach the effect of putting things right once and for all.
