Problems solved by technology

Due to the large amount of gap sensors used in maglev trains and the heavy workload of calibration and maintenance, the effectiveness and reliability of the gap sensor calibration system are very high. However, the traditional gap sensor calibration system only uses cables to control the calibration sensor. The measurement gap of the gap sensor is calibrated, but the measurement speed of the gap sensor cannot be calibrated. This system cannot meet the horizontal moving speed requirements of the gap sensor calibration, and there are hidden dangers of cable wear and tear

Description

technical field [0001] The invention relates to the field of maglev trains, in particular to a calibration system for a multi-probe gap sensor of a maglev train. Background technique [0002] During the operation of the low-speed maglev train, the vehicle does not have direct contact with the track, but relies on electromagnetic force to achieve non-contact suspension, so a large number of gap sensors are used. However, in the actual production process, the characteristics of each sensor cannot be completely consistent. Generally speaking, there are differences in the linearity and output range of the original signal output by the sensor, and because the maglev train track is spliced ​​by segmented steel rails , There is a seam between the tracks, and when the general gap sensor passes through the gap, the measured gap value will be greater than the actual value. Therefore, each gap sensor needs to be calibrated during production and maintenance. The calibration process is ...
