System and method for removing snow or sundries for train infrared shaft temperature detection equipment

Abstract

The invention provides a system and method for removing accumulated snow or sundries for train infrared axle temperature detecting equipment, and belongs to the field of railway assisted control systems. The problem that in severe snowing weather, due to the fact that snow and sundries enter a detection window, an infrared detection light path of the infrared axle temperature detecting equipment for measuring the train axle temperature is affected, and the measuring precision is affected accordingly can be solved. The system comprises a rain and snow sensor, an ambient temperature sensor, an air source mechanism, two air pipes and a bellows. The air source mechanism comprises a box, and an external air blower, an internal air blower and a controller are arranged in the box. Whether it snows can be accurately judged according to signals of the ambient temperature sensor and signals of the rain and snow sensor, and the air pipes are controlled to directly stretch into a train axle temperature measuring device to sweep the edge of a temperature measuring probe. The upper surface of the train axle temperature measuring device is swept again after delaying, the temperature measuring probe is prevented from being shielded by ice, snow and sundries on the surface again, and the temperature measuring precision is guaranteed.

Description

technical field [0001] The invention belongs to the field of railway auxiliary control systems. Background technique [0002] The shaft temperature of the train needs to be monitored online during operation. The commonly used detection equipment for the shaft temperature of the train is infrared shaft temperature detection equipment. The top of the equipment is equipped with an infrared detection window for temperature collection. In actual use, this kind of equipment will be arranged along the railway track, most of which are located in the field. This kind of equipment has fast measurement speed and high precision, but it will be affected by bad weather, especially in the north. When there is snow, the snow will block the detection window, which will affect or even hinder the measurement path of infrared rays, making the measurement inaccurate or even impossible. In addition, the snow in the north is often accompanied by strong winds, which will cause snow and even some d...
