Railway vehicle compressed air humidity detection and display device

Abstract

The invention is suitable for the technical field of railway vehicle detection, and provides a railway vehicle compressed air humidity detection and display device which comprises an air pipeline and a train control and management system. The air pipeline is provided with a compressed air humidity detection module, the compressed air humidity detection module is electrically connected with the train control and management system, the compressed air humidity detection module further comprises a box body with an opening in the front face and an air circuit board, and the air circuit board is matched with the opening in the front face of the box body. According to the railway vehicle compressed air humidity detection and display device, the humidity of compressed air can be detected and displayed according to pressure setting, so that the problem of false alarm is avoided, and whether the humidity of the compressed air is qualified or not can be indicated through a red lamp or a green lamp of an indicator lamp according to the air humidity; it is convenient for maintenance manual to observe and check, a pressure switch and a humidity sensor can be calibrated at any time through external equipment, so that manual operation is facilitated.

Description

technical field [0001] The invention belongs to the technical field of rail vehicle detection, in particular to a rail vehicle compressed air humidity detection and display device. Background technique [0002] There are many systems using compressed air in rail vehicles, such as air brake systems, air spring suspension systems, and pneumatic pantograph systems. Compressed air is used as a medium. Excessive humidity will cause corrosion or even failure of system parts and pipelines. Under normal circumstances, the air source system will be equipped with a dryer to dry the compressed air to ensure that the parts and pipelines are not corroded. If the dryer fails or the desiccant fails, it is crucial to quickly and accurately judge the humidity state of the compressed air. important. [0003] In the prior art, the dew point meter specially used to measure the humidity of compressed air is connected to the test joint installed on the pipeline, and the humidity of the compresse...
