Sealing performance detection method and device for vehicle-mounted detection equipment

Abstract

The invention discloses a sealing performance detection method and device for vehicle-mounted detection equipment, and the method comprises the steps: sensing the resistance change generated by accumulated water through an electrode detection module disposed in the vehicle-mounted detection equipment, and generating a corresponding level signal; detecting a temperature parameter and a humidity parameter in the vehicle-mounted detection equipment through a temperature and humidity detection module configured in the vehicle-mounted detection equipment; judging whether accumulated water exists in the vehicle-mounted detection equipment or not through the processing module according to the level signal, and judging whether water vapor exists in the vehicle-mounted detection equipment or not according to the temperature parameter and the humidity parameter. According to the invention, the problem that the sealing performance detection needs to be implemented outside the vehicle-mounted detection equipment in the prior art, so that extra vehicle operation dangers are caused can be solved.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a method and device for detecting airtightness of vehicle-mounted detection equipment. Background technique [0002] Leakage due to sealing problems is an important problem faced by the daily operation and maintenance of railway on-board testing equipment, especially on-board testing equipment installed on the top of railway vehicles, which is exposed to outdoor environments all year round and runs at high speed with railway vehicles. Complex and changeable, this puts forward high requirements on the sealing performance of on-board testing equipment. If there are defects in the design or production of the vehicle-mounted testing equipment, it will cause leakage in rainy and snowy weather and high-speed operating environments, or water droplets or water vapor enter the interior of the vehicle-mounted testing equipment on the roof. If the level is too high, it will lead to probl...
