Embodiment 1

[0047] Such as figure 1 Shown:

[0048] A joint GPS / Beidou trusted judgment TAXI meter accuracy working method:

[0049] Comparing the similar data of the taxi meter and GPS / Beidou positioning system every second or several seconds, calculate the distance error of the taxi meter: if the distance error is less than or equal to the preset error threshold, the vehicle error information will be stored as the original data To be checked, the vehicle error information includes vehicle number, time, location, meter display distance and error; if the error is greater than the preset error threshold, the vehicle error information will be stored as raw data to be checked, and the vehicle error information will be transmitted at the same time To the taxi management platform.

[0050] The similar data of the meter and GPS / Beidou positioning system per second or several seconds refers to: mileage data or pulse data:

[0051] The mileage data is the mileage recorded by the meter and the ac...

Embodiment 2

[0057] Such as figure 2 Shown:

[0058] A device for joint GPS / Beidou credible judgment of the accuracy of the TAXI meter, including a processing module, a meter connected to the processing module, a storage module and a GPS communication module, and the power supply module provides power for all the above-mentioned modules, The processing module obtains the distance of this ride by the taximeter; the processing module is a single-chip microcomputer with processing capability, which is used to calculate the distance error of the taxi meter, and is transmitted to the storage module; the storage module is used to store all Detected vehicle error information; the GPS communication module is used for communication with the taxi management platform and GPS data collection.

Embodiment 3

[0060] A kind of application of device as described in embodiment 2, comprises steps as follows:

[0061] (1) Passengers get on the bus, the driver turns off the empty lights, and the device that combines GPS / Beidou Trustworthy to judge the accuracy of the TAXI meter starts to work;

[0062] (2) After the vehicle starts to drive, the processing module reads in the similar data of the meter and GPS / Beidou positioning system every second or several seconds, and calculates the distance error of the taxi meter; when the distance error is less than or equal to When the threshold error is preset, proceed directly to step (4); when the distance error is greater than the preset threshold error:

[0063] The device sends a warning vehicle information to the taxi management platform, including the vehicle number, time, place, distance and error displayed by the meter; meanwhile, the above-mentioned warning vehicle information is packaged as raw data and stored in the storage module to b...

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 [0001] The invention relates to a GPS / Beidou credible judgment TAXI meter accuracy working method and a device thereof, and belongs to the technical field of taxi meter supervision and detection devices. Background technique [0002] Since the advent of taxis, the researchers of the taxi meter error verification system technology have been studying how to test the taxi meter error more accurately and quickly. This research work has very important practical significance. Using GPS / Beidou to detect the use error of taximeters has a broad application prospect in error verification. [0003] As a part of public transportation, taxis are a window for urban mobility, representing the image of a city, and as a metering instrument for operating settlement on taxis—taximeters, which safeguard the interests of both drivers and passengers. However, the known traditional taximeters do not have the function of analyzing the signal of the pricing sensor. There are always ...
