AI Technical Summary

Technical Problem

The timing error during the commissioning of the plug doors on the high-speed train is large and the accuracy is low. Moreover, the existing methods require manual intervention, resulting in low construction efficiency.

Method used

A vibration sensor is used to collect vibration signals when the sliding door is opened and closed. The signals are then processed by a comparator and converted into electrical signals. A timing chip is used to calculate the opening and closing time, and a microcontroller is used to display the results.

Benefits of technology

It enables precise calculation of the opening and closing time of the sliding door, reduces human error, and improves construction efficiency.

Abstract

This invention provides a timing method and system for opening and closing a sliding door, comprising: using two large vibrations during the opening and closing of the sliding door as a signal source; using the signal source as the start and end points of the timing process; converting the interval frequency signal collected within the start and end points of the timing process into a time signal; and calculating the specific time used for opening and closing the sliding door based on the time signal.
