AI Technical Summary

Technical Problem

When EMUs operate in winter, condensation is likely to form on the sliding doors and end inner walls, causing corrosion of electronic components and damage to interior trim, and the protective effect of existing insulation materials and sealing strips gradually weakens.

Method used

The data acquisition module is used to monitor the temperature and humidity of the sliding door and the end in real time. The temperature and humidity are controlled by the sliding door heating module and the end warm air module. The threshold is set to judge and automatically adjust the heating device of the sliding door and the end to prevent the formation of condensation water.

Benefits of technology

Effectively prevent the formation of condensation water, extend equipment life, ensure normal operation of trains and passenger health, and improve the comfort of the interior environment.

Abstract

The invention relates to an anti-condensation system and method for a sliding plug door and an end part of a motor train unit, and the system comprises a data obtaining module which is used for detecting the real-time temperature of the sliding plug door, and the real-time temperature and the real-time humidity of the end part; a sliding plug door heating module; an end warm air module; the control module is configured to set a first sliding plug door temperature threshold value, a first end part temperature threshold value and a first end part humidity threshold value; the real-time temperature of the sliding plug door and the real-time humidity of the end portion are obtained, whether the temperature of the sliding plug door is lower than or equal to a first sliding plug door temperature threshold value or not is judged, whether the real-time humidity of the end portion is higher than or equal to a first end portion humidity threshold value or not is judged, and if yes, a sliding plug door heating module is controlled to increase the temperature of the sliding plug door; and the real-time temperature of the end part is obtained, whether the real-time temperature of the end part is lower than or equal to a first end part temperature threshold value or not is judged, and if yes, the end part warm air module is controlled to increase the temperature of the end part. Through the application, the problem that the anti-condensation effect of the sliding plug door at the end part of the vehicle and the inner wall at the end part is poor is solved.
