Embodiment 1

[0031] Embodiment 1: A rail car intelligently detects the installation position of the emergency braking device during the construction phase of the subway track

[0032] The infrared sensor is installed on the roof of the rail car to detect whether there is a person in the tunnel in the running direction, and if there is a person, it will return the distance signal between it and the rail car.

[0033] The ultrasonic sensor is installed on the lower side of the window of the cab of the rail car, and is used to detect whether there is an obstacle in the tunnel in the running direction, and if there is an obstacle, it will return the distance signal between it and the rail car.

[0034] The camera is installed at the connecting hook of the rail car, and is used to return the real-time images in the tunnel in the running direction, and use image processing technology to review the status of personnel and obstacles in the tunnel.

Embodiment 2

[0035] Embodiment 2: A method of using an intelligent detection emergency braking device for rail cars during the construction phase of a subway track

[0036] Before starting the device, it is first necessary to confirm whether the infrared sensor, ultrasonic sensor and camera are working normally. After confirming that the above sensors are working normally, the rail car driver should drive according to the normal rail car driving rules.

[0037]During the operation of the rail car, the device obtains the information in the tunnel at the front end of the running direction through infrared sensors, ultrasonic sensors, and cameras. The infrared sensor is mainly used to detect whether there is a person in the front tunnel, and if there is a person, it will return the position information between the person and the rail car. The ultrasonic sensor is mainly used to detect whether there is an obstacle in the front tunnel, and if there is an obstacle, it will return the position i...

Abstract

The invention relates to the technical field of rail engineering, in particular to an intelligent detection emergency braking device for a rail car in the subway rail construction stage and a using method. First collecting equipment is used for detecting whether people exist in a tunnel in the running direction or not; second acquisition equipment is used for detecting whether an obstacle area exists in the tunnel in the running direction; third acquisition equipment is used for acquiring real-time image information in the tunnel; the first collecting device, the second collecting device, the third collecting device and the vehicle-mounted terminal are in signal connection, and the vehicle-mounted terminal is used for controlling emergency braking of the rail car. 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 that the driving safety is improved. Therefore, 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 an intelligent detection emergency braking device for 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...
