Description

A monitoring device for rail vehicles

technical field

The utility model relates to the technical field of rail transportation, in particular to a monitoring device for rail transportation tools.

Background technique

In the fully automatic driverless line of urban rail transit, the active obstacle detection system has become one of the necessary functions of the smart train. When a foreign object is detected, an alarm will be sent to the control center and the driver in real time, and the type and distance of the identified foreign object will be detected to improve the reliability of line operation and reduce operation and maintenance costs.

At present, the commonly used sensors in existing rail vehicle obstacle detection systems include cameras, millimeter-wave radars, and lidars, each of which has its own advantages and disadvantages in application. Among them, the camera is image-based, capable of distinguishing shapes and colors, and plays a key role in obstacle type recognition. Compared with other sensors, the cost is low, but the performance of the camera is not good in extreme weather, such as rain, fog, and insufficient light. Under normal circumstances, the transparent cover in front of the camera lens will be easily contaminated with rainwater, sewage and dust. If it is not cleaned for a long time, it will lead to unclear shooting. Most of the existing technologies use spray or wiper to clean the surface of the camera optical glass. On the one hand, most of the spray cleaning methods directly spray the camera with water or water mist. After spraying, the surface is difficult to dry quickly, which affects the use of the camera. The impurities will scratch the glass surface along with the movement of the wiper. To this end, we propose a monitoring device for rail vehicles.
