Description

TECHNICAL FIELD

[0001] The utility model relates to passenger flow monitoring equipment technical field, especially passenger flow monitoring device for hub station. BACKGROUND

[0002] At present, most passenger flow monitoring devices are installed on the ceiling of the station passage, in order to monitor different entrance of the station, multiple monitoring devices are needed to fix the angle to monitor the entrance in real time. The camera obtains image information and transmits the information to the data preprocessing unit through the interface, and performs preprocessing operations such as cleaning, denoising and format conversion on the collected data. The pedestrian density calculation unit in the peripheral system uses a pedestrian density estimation algorithm based on video and mobile device signals to calculate the pedestrian density in different areas, and fuses and calibrates the results of the two methods, uses multi-view video images to reconstruct a three-dimensional scene, and generates a real-time updated three-dimensional model of the station area. The peripheral system displays the real-time passenger flow of the station in a visual manner through a large screen display or a monitoring terminal. However, there are some defects in the way the monitoring device obtains information in this process.

The passenger flow monitoring device for subway station has a reasonable structure, does not need to be manually adjusted by staff, saves time and effort, easily corrects the angle, reduces the labor intensity of the staff, avoids the subway congestion caused by the maintenance of the passenger flow monitoring device, is easy to disassemble, and improves the use efficiency of the passenger flow monitoring device.

[0004] The existing technology has the following problems:

[0005] Firstly, the connection between the device shell and the mounting disc is through the clamping of the first clamping block and the second clamping block. According to the actual situation, the motor will generate vibration when it is running, and the camera in the station needs to be adjusted to obtain information. The first clamping block and the second clamping block will deviate and cause the shell to loosen due to long-term vibration. Secondly, the adjustment of the camera in the vertical direction in the above-mentioned device is realized by using the rotation of the motor, the gear and the tooth structure. The third connecting rod is retracted or extended into the sliding groove to adjust the rotation angle of the camera, which affects the appearance, and the gear and rack cannot realize self-locking, which may occur rotation.
