Embodiment 1

[0032] The safety device for the visual operation of the rail car during the construction phase of the subway track adopts a split design, and is mainly composed of a camera installed in the tunnel, an image integration processing device, a data collection device, and a vehicle-mounted terminal. The camera in the tunnel is set on the tunnel wall, which meets the requirements of the rail car running limit in the tunnel. The camera, image integration processing equipment and data summarization equipment are connected through a wired network. The data aggregation device sends information to the vehicle terminal through the wireless network.

[0033] The image acquisition equipment in the tunnel is used to obtain real-time image information in the tunnel. Specifically, the cameras of the image acquisition equipment are placed in pairs on both sides of the tunnel wall at a fixed distance, and can simultaneously observe the tunnel in the direction of large mileage and small mileage....

Embodiment 2

[0038] Before the device is used, it is necessary to divide the running section of the rail car into independent sections according to the arrangement of the cameras through the program. The state of each section can be acquired through the camera and analyzed by the image integration processing device to determine whether there are people or obstacles in the section. For example, the camera is arranged with a pair of cameras every 25 meters, facing the direction of the large mileage and the small mileage respectively. The observation range of each camera is 12.5 meters, and the image in the tunnel is sent to the integrated image processing device for processing through the wired network.

[0039]When the rail car driver is driving, turn on the on-board terminal, set up the distribution port to receive the information sent by the data collection device, including the position of the current section of the rail car in the section, whether the several sections in front of the rai...

Abstract

The invention relates to the technical field of rail engineering, in particular to a subway rail construction stage rail car visual operation safety device and a using method. The subway rail construction stage rail car visual operation safety device comprises an image collecting and processing device and a vehicle-mounted terminal, and the image collecting and processing device comprises an image collecting device and an image integrated processing device; the image integrated processing equipment is in signal connection with the image acquisition equipment and is used for identifying the real-time image information and obtaining processed image information; and the vehicle-mounted terminal is in signal connection with the image acquisition and processing device and is used for braking according to the processed image information. The light and efficient safe driving auxiliary device is designed, in the driving process, a driver is reminded whether obstacles exist in the running direction or not and the driving is affected, and in the case that emergency obstacle avoidance is needed, the auxiliary device can directly control the rail car to conduct emergency braking operation, so the safe driving of the rail car in the urban rail transit construction stage is ensured.

Description

technical field [0001] The invention relates to the technical field of track engineering, in particular to a safety device for visually running rail cars during the construction phase of a subway track and a method for using it. Background technique [0002] As a means of transporting materials such as rails, rail cars are widely used in the construction phase of urban rail transit in my country. However, along with its wide application, correspondingly, the problem of the safety of rail cars has also arisen. [0003] During the running of the existing rail car, the driver can ensure the safe driving of the rail car by observing the situation of the tunnel ahead. However, in the process of urban rail construction, harsh factors such as strong light and smoke may appear in the tunnel to affect the driver's observation of the tunnel. At the same time, because the operators need to transport materials through the trolleys in the tunnel, the safety of the rail cars is also red...
