15 November 2011Measurement error analysis of taxi meter
The error test of the taximeter is divided into two aspects: (1) the test about time error of the taximeter (2) distance test
about the usage error of the machine. The paper first gives the working principle of the meter and the principle of error
verification device. Based on JJG517 - 2009 "Taximeter Verification Regulation ", the paper focuses on analyzing the
machine error and test error of taxi meter. And the detect methods of time error and distance error are discussed as well.
In the same conditions, standard uncertainty components (Class A) are evaluated, while in different conditions, standard
uncertainty components (Class B) are also evaluated and measured repeatedly. By the comparison and analysis of the
results, the meter accords with JJG517-2009, "Taximeter Verification Regulation ", thereby it improves the accuracy and
efficiency largely. In actual situation, the meter not only makes up the lack of accuracy, but also makes sure the deal
between drivers and passengers fair. Absolutely it enriches the value of the taxi as a way of transportation.
