Portable intelligent speedometer tester and using method thereof

Abstract

The invention discloses a portable intelligent speedometer tester and a using method thereof, belongs to the technical field of automatic detection, and particularly relates to an intelligent tester for testing a plurality of speedometers of an airplane, a steamship, a train, a car and the like simultaneously. The portable speedometer tester based on a DSP (Digital Signal Processor) is characterized in that the tester can test speedometers to be tested without rotating the speedometers, thus equipments such as various shafts, a speed regulator, a belt driving mechanism, a roller and the like are saved; a plurality of speedometers can be tested automatically and simultaneously, measured values of the speedometers to be tested can be collected in real time, and errors can be recorded and analyzed; the tester can test speedometers used on various rotating machines through real-time maintenance of parameters; and the tester solves the problems that the traditional testing table has narrowapplication range, is inconvenient to carry, has high labor intensity and low working efficiency and the like.

Description

technical field [0001] The invention relates to a portable speedometer intelligent tester and a method for using the same, belonging to the technical field of automatic detection, and in particular to an intelligent tester capable of simultaneously detecting multiple speedometers such as airplanes, ships, trains and automobiles. Background technique [0002] The vehicle speedometer is an important instrument to monitor the driving of the vehicle, and its integrity and accuracy are directly related to the driving safety of the vehicle. In order to ensure the driving safety of motor vehicles and avoid road traffic accidents caused by inaccurate speedometers, according to Article 9 of the "Measurement Law of the People's Republic of China" and Article 25 of the "Detailed Implementation Rules for the Measurement Law of the People's Republic of China", the Measuring instruments must be periodically calibrated in accordance with the law, and the longest calibration period shall no...

AI Technical Summary

Problems solved by technology

[0004] The present invention is a portable speedometer intelligent tester and its use method, aiming at the limitations of the above-mentioned disclosed calibration platform, providing a device that can be calibrated without rotating the speedometer to be tested, which saves Various shafts, speed regulating devices, belt transmission mechanisms, rollers and other equipment have been removed, and the automatic calibration of multiple speedometers can be realized at the same time, and the measured values ​​​​of the speedometers to be tested can be collected in real time to record and monitor their errors. Analysis, through the real-time maintenance of parameters, the verification of various rotating machinery speedometers can be realized, so as to solve the problems of narrow application range, inconvenient portability, high labor intensity and low work efficiency of the existing verification platform. The present invention is based on DSP Technical solution of portable speedometer tester and method of use thereof
