Abstract

The invention discloses a speedometer sensor calibration system. The system includes a signal generating device and an electrical control device. The signal generating device includes a driving part and a clamping part. The clamping part clamps the sensor under test or the probe of the sensor under test installed on the motor vehicle, and then the electric control device sets the first set rotation speed of the driving part according to the sensor model and the current clamping parameters, so that the driving part can be The first set rotational speed rotates the clamping portion. Finally, the electrical control module acquires the second rotational speed of the sensor under test, and compares it with the first set rotational speed to automatically generate a measurement certificate for the sensor under test. The invention can also complete the calibration work without disassembling the sensor from the motor vehicle, which improves the calibration efficiency and is easy to carry.

Description

technical field [0001] The invention relates to the technical field of instrument calibration, in particular to a speedometer sensor calibration system. Background technique [0002] The speedometer is a special measuring instrument used to measure the speed of the train. The speedometer indicator is installed on the driver's console of the locomotive or EMU. In the field of locomotives or motor vehicles, magnetoelectric speedometers and photoelectric speedometers are generally used to measure the speed of locomotives. The indication of the speedometer depends on the vehicle speed sensor. The sensor is installed on the gearbox to measure the different speeds of the locomotive to obtain different pulse signals, which are then converted into pointer output, so that the driver on the driver's console can pass the speedometer indicator. Check the current speed. [0003] In order to ensure the safety of motor vehicles, the display speed of the general speedometer indicator is s...
