Description

Technical Field

[0001] The utility model relates to the technical field of station monitoring, in particular to a station monitoring video processing device. Background Art

[0002] The passenger service system of large passenger stations is relatively complete, the scale of various passenger service information is large, and the construction investment is also large. It is easier to create an information integration platform to concentrate all passenger service information and video surveillance systems on this platform. However, for medium or lower passenger stations, the passenger service system is simple, small in scale, and the investment is also small. This technology is suitable for the needs of passenger transportation in medium stations, giving full play to the role of existing video surveillance equipment in stations, and using computer vision technology to collect and analyze video surveillance images of medium stations, analyze and count passenger flow in waiting rooms in real time, and monitor the station's reception and dispatch of trains. These data are uploaded to the medium-sized station passenger service integration platform for unified summary.

[0003] The video surveillance systems of medium-sized stations are of various types and independent due to their different construction periods. They adopt a discrete system mode, and the information between the monitoring systems cannot be shared. Some sudden dangerous situations have to be completely completed by manual visual inspection or video playback, which is relatively inefficient. In order to ensure the improvement of monitoring efficiency, video processing devices are currently installed in each medium-sized station to synchronize the video time and share transmission. However, since the video processing device does not work intermittently, it is easy to heat up inside. The current video processing device is equipped with an intermittent cooling fan to blow out the internal heat through the heat dissipation net. When the fan is not working, external dust can easily enter through the heat dissipation net, resulting in serious dust accumulation inside the video processing device, affecting its normal operation and life. Dust accumulation not only leads to a decrease in heat dissipation efficiency, but also may cause safety problems such as circuit short circuit, thereby further reducing the stability and reliability of the video surveillance system.
