Description

Monitoring method and apparatus for railway vehicles and tracks {The Method And Apparatus For Monitoring a Train And Railway Line}

The present invention relates to a monitoring method and apparatus for a track for safety on a track on which a high-speed train operates.

More specifically, in the case of high-speed trains, when the train is required to stop due to human and materialized accidents in its operation, work on the track that occurs while the train is running, delays or breakdowns of the preceding trains, The track operator recognizes only the transmitted stop signals or warnings, but in order to identify more precisely the situation that occurred in front, all the information related to the track can be sent directly so that the image information about the situation can be directly transmitted. The present invention relates to a monitoring method and apparatus for a track that can collect and transmit information so that it can be monitored at an appropriate time.

As trains become faster and faster, the braking distance becomes longer and longer, so even if the train operator visually detects other trains, people, or obstacles on the track, it is inevitable that an accident will inevitably occur. Great damage occurs. There are many people in history, especially when the train is long or the track is curved so that the back of the vehicle is not visible to the train operator. There is a need for a surveillance system for personal accidents at crossings where vehicles or people enter and exit.

Hereinafter, with reference to the exemplary drawings will be described in detail the configuration and operation of the embodiment of the monitoring method and apparatus for a railway vehicle and track according to the present invention.

The core of the present invention is not limited to risk factors of railway operation at a specific point such as a platform of railroad station and a railroad crossing of a conventional railway station, but by a conventional warning signal for a section in which a railway is connected or when a vehicle is connected at a railway station. In order to improve the stopping, the cameras around the tracks of the recently installed trains can be used to take appropriate measures to train operators or on-track operations managers through a more accurate image of the situation on the train. It is a method and apparatus for monitoring rail vehicles and tracks.

As shown in FIG. 5, a monitoring method and apparatus for a railroad vehicle and a track which provides a more accurate image of a situation occurring in a train operation section and a historical neighborhood according to an embodiment of the present invention include a photographing unit 200, The information collecting unit 210, the intelligent situation recognition unit 220, the camera state management unit 230, the situation information management unit 240, the information transmission unit 250, the output unit 260.

The photographing unit 200 is installed at regular intervals in the train operation section includes a camera for photographing the track side situation in a certain angle range and a transmitter for transmitting the image taken from the camera to the information collecting unit 210.

Preferably, the camera in the photographing unit 200 operates at all times, but only the camera within a predetermined range of a section and a traveling direction in which the train is operated may be operated to prevent prolonging the life of the camera and power consumption. It has a self-diagnosis function that diagnoses the condition in the camera in order to be able to maintain and repair the camera located at.

The information collecting unit 210 converts the image from the photographing unit 200 by analog / digital converter, digital image information, camera status information diagnosed by a camera's self-diagnostic function, and trains and cameras in operation. In addition, each location information is collected from the track operator and stored in memory.

The intelligent situation recognition unit 220 analyzes each of the digital image information stored in the memory of the information collecting unit 210, detects a dangerous situation such as a person or an obstacle on a train section line, and provides warning and danger information. Send it to the situation information management unit.

The intelligent situation recognition unit detects a danger and compares the two digital images previously acquired based on the present by pixel unit by dividing the information collection unit which is continuously transmitted from each camera and stored as a digital image in a predetermined time unit. Obstacles and moving objects can be checked according to the color change.

The object recognition algorithm of the digital image classifies and stores objects in the digital image and then classifies them into individual units of photographed digital images to detect obstacles and moving objects through differences from conventional objects. .

It is relatively easy to determine the appearance of a specific obstacle or the appearance of a moving object such as a person because there is no change of image on the railroad on which the train is operating.

The camera state management unit 230 is a malfunction of each camera according to the self-diagnosis results that can be confirmed from the normal operation of each camera installed on the track change stored in the memory of the information collecting unit 210 and the important device of the camera By judging whether the camera is repaired or replaced, it is determined whether the transmitted image information is reliable.

The situation information management unit 240 is a situation set by the intelligent situation recognition unit 220 and the camera state management unit 230 and the state information of each camera or a set of information to the person who needs the information manually Whether or not to pass. For example, when a dangerous situation is recognized by the dangerous situation detection algorithm of the intelligent situation recognition unit 220, the situation information management unit 240 warns of a dangerous situation and trains of the train operator and the central control room of the train following the image. Alternatively, it selects and transmits it among the track workers, and transmits the information to the central control room or the service provider when a malfunction problem occurs from the state of each camera installed on the track.

The information transmitting unit 250 transmits the information by wire or wireless to the train operator, the central control room or the company of the selected train from the situation information management unit 240.

The output unit 260 receives the image information transmitted from the information transmission unit 250 and the image information transmitted from the receiver and outputs the received image information to the display on the output system of each user.

In the present specification, a preferred embodiment of a monitoring method and apparatus for a railroad vehicle and a track according to the present invention has been described, but the present invention is not limited thereto. The invention may be practiced in various ways within the scope of the claims and the accompanying drawings, which also belong to the scope of the invention.
