Abstract
The invention relates to a working method for credibly judging TAXI taximeter accuracy by combining GPS (global positioning system) and Beidou positioning system. The method includes the steps: comparing homogeneous data of a taximeter and a GPS/ Beidou positioning system every second or a few seconds, calculating a distance error of the TAXI taximeter, and taking vehicle error information as original data to be stored and inspected if the distance error is smaller than or equal to a preset error threshold value; taking the vehicle error information as original data to be stored and inspected and transmitting the vehicle error information to a TAXI management platform if the distance error is larger than the preset error threshold value. The vehicle error information includes vehicle numbers, time, sites, taximeter display distances and errors. By the aid of the working method and the working device for credibly judging TAXI taximeter accuracy by combining GPS (global positioning system) and Beidou positioning system, distance data of the taximeter and the GPS data are compared and analyzed, the problem that illegal valuation signal information cannot be wirelessly communicated and transmitted is solved, and violation and cheating are thoroughly eliminated.
Description
Technical field
The present invention relates to the credible judgement of associating GPS/ Big Dipper TAXI fee register accuracy method of work and device thereof, belong to the technical field of taximeter supervision pick-up unit.
Background technology
Since coming out from taxi, how more the researchist of taximeter error testing systems technology in the research calibrating taximeter error of accurate quick, and this research work has considerable realistic meaning.Utilize the GPS/ Big Dipper to detect taximeter use error and aspect error testing, have comparatively wide application prospect.
Taxi, as a part for public transport, is the window of a Urban Migrant, represents the image in a city, as measurement instrument---the taximeter for operating and settling accounts on taxi, is safeguarding driver and passenger both sides' interests.But, known traditional taximeter does not all carry out analytic function to valuation sensor signal, always there are some taxi drivers to utilize the functional defect of traditional fee register, run counter to sincere principle of managing, for many " drawing " count out money, use various fraudulent meanses, infringement passenger's interests, make department take advantage of ask that contradiction is continuous, disturbed the normal transportation order of taxi trade, damaged the image in city.
Fraudulent means common in operation has:
1, utilize the size cheating of tire, giant tyre changes little tire and uses the tire of hiring a car and move the identical number of turns, and actual distance of passing by is less than fee register record certainly, that is to say that fee register jumps soon;
2, utilize gearbox gear cheating, the pulsation wheel of former car is replaced by the less pulsation wheel of the number of teeth, has improved ratio of gear, makes the revolution of ratio of revolution wheel of the sensor of fee register high, allows fee register jump fast;
3, utilize mechanical switch control cheating, external micromachine or pulse producer in fee register sensor signal lines, by mechanical switch control, arbitrarily make fee register jump fast;
4, utilize fee register clock to adjust function cheating, utilize the clock of fee register to adjust function, deliberately the time of the permanent clock of fee register is adjusted forward, make fee register enter in advance night running state, to reach the object of collecting in advance night running subsidy;
5, remote control cheating, external signal generator in fee register sensor signal lines, produces valuation signal by telepilot control signal generator, and arbitrarily change valuation transducing signal, allows fee register jump fast.
Especially Lung biopsy, because disguise is strong, volume is little, easy to operate, and illegal taxi driver uses quite general.
Taxi management at different levels department utilizes in order to hit illegal driver that fee register is taken advantage of visitor, the behavior of ripping off the customer, and has adopted various counter-measures, mainly contains:
1, strengthen the metering performance of taximeter to detect and supervision and management;
2, strengthen the professional ethics quality-oriented education to practitioner, their service behavior of standard;
3, strengthen inspection, improve punishment;
4, GPS is installed.
Although taxi management at different levels department adopts multiple counter-measure, but due to the intrinsic defect of traditional taximeter, and minority taxi driver professional ethics is low, taxi driver utilizes the phenomenon of the many valuation of fee register often to have generation, taxi management department can not find in time, even if find, owing to there is no evidence, also cannot effectively process illegal driver, this has just connived illegal driver more.Current traditional taximeter can not solve minority driver and utilize that fee register is valuated, the problem of overcharge more, seriously hinders the lifting of city image and the construction of harmonious society.
More domestic research institutions also drop into the research of this respect one after another.But until at present, taximeter the machine timing calibrating of domestic many taximeter error testing systems and taxi use error are had the records of distance by the log and examined and determine is all also relatively independent carrying out, not single wasting manpower and material resources, detection speed is also slower.
Improve the performance of taximeter error testing system and realize more function, need to improve and upgrading application software.Software upgrading is just had higher requirement to the calculation process ability of microprocessor.And in taximeter error testing system, due to will be to hyperchannel Continuous Tracking, real time data calculation process amount be large, therefore higher to the performance requirement of microprocessor.Except performance, power consumption and volume are also had high requirements.
Current, in the urgent need to developing a kind of taximeter error testing system detector, can realize detection taximeter use error accurately and fast.
Fee register calculates the principle of distance: in vehicle spindle (or on output shaft of wheel box), electromagnetism (or photoelectricity) sensor is installed, main shaft often rotates a circle, and produces an electromagnetism (or photoelectricity) pulse, utilizes counter, recording impulse number.Consider transmission speed ratio, can obtain the rotating cycle of wheel, then consider wheel diameter, utilize girth formula, can draw the distance travelled of vehicle.
Summary of the invention
For the deficiencies in the prior art, the invention provides the credible judgement of a kind of associating GPS/ Big Dipper TAXI fee register accuracy method of work.The object of the method for the invention be solve existing taximeter error testing system to the timing calibrating of fee register the machine and use error the calibrating of having the records of distance by the log can only relatively independently carry out, not only wasting manpower and material resources, and also slower problem of detection speed.
