Description

Technical Field

[0001] The present invention relates to the technical field of urban rail transit, and in particular to a method for processing view data return for obstacle recognition. Background Art

[0002] In the urban rail transit industry, trains are encouraged to be equipped with active obstacle detection devices to proactively identify risk factors that affect the safe operation of trains, such as foreign objects in front of the train, severe deformation of tracks and other structures, and personnel in the track area, and to promptly issue alarms and push relevant image information. At the same time, users have proposed that after the active obstacle detection device alarms, the image information it identifies can be uploaded to the center for dispatchers to confirm the cause of the alarm.

[0003] The perception-based Train Eagle Eye System (ITE) is a system that integrates data through multiple sensors such as cameras and lidars, and uses core technologies such as artificial intelligence, image recognition, and edge computing to achieve active environmental perception of the train, including trains, obstacles, tracks, and signals. The system can be used to improve the driving safety of manual driving when the on-board control system fails.

[0004] During the operation of the train, the ITE subsystem provides active obstacle detection results in real time. When the ITE subsystem identifies an obstacle, an alarm is issued at the automatic monitoring subsystem (ATS) workstation in the control center, and the dispatcher retrieves the obstacle image information of the designated train. The ITE subsystem transmits the obstacle image information (including obstacle calibration results) to the ATS subsystem according to certain principles.

[0005] The existing technology only realizes the interaction between the ATS system and the ITE system, and cannot link the obstacle alarm information with the camera illuminating the track surface, and cannot realize the linkage output of the view data to the ATS dispatching workstation. Summary of the invention

[0006] In order to solve the above problems, the present invention provides a method for returning view data of obstacle identification. When the ITE system identifies the existence of an obstacle in the line, the obstacle information is provided to the on-board controller (VOBC), and the ATS system generates a first-level pop-up alarm to prompt the dispatcher, and displays an obstacle icon in front of the train on the interface. The VOBC sends the effective obstacle identification point of the activation end to the train control management system (TCMS), which is forwarded to the on-board PIDS system by the TCMS, and the driver's cab is linked to illuminate the track surface camera image and push the camera image T time before the obstacle is identified to the OCC large screen.

[0007] The present invention provides a method for processing view data return for obstacle identification, and the specific technical solution is as follows: When the ITE system identifies an obstacle in the line, it transmits the obstacle location alarm information to the VOBC; The alarm information is transmitted to the on-board automatic train overspeed protection system ATP through VOBC. The on-board ATP forwards the obstacle alarm information to the ATS system and displays the output at the ATS dispatching workstation in the control center; The alarm information is transmitted to the vehicle-mounted interactive system MMI through VOBC. After receiving the alarm information, the MMI continuously outputs the alarm prompt sound until the train stops in front of the obstacle; After receiving the alarm information, VOBC will forward the effective obstacle identification points at the activation end to the on-board public information display system PIDS through the TCMS system. The on-board PIDS will simultaneously drive the driver's cab to illuminate the track surface camera to obtain the real-time image and the image at the set time before the obstacle is identified, and upload and return the view data for scheduling.

[0008] Furthermore, when the ATS dispatch workstation at the control center displays the output, the kilometer mark where the obstacle is located is output and displayed.

[0009] Furthermore, the ATS dispatch workstation in the control center displays the output as follows: When the train identifies an obstacle but has not yet entered the ITE identification blind area, the ATS system outputs a first-level pop-up alarm to prompt the dispatcher. At the same time, the dispatch interface of the ATS dispatch workstation marks an obstacle icon in front of the train.

[0010] Furthermore, when the train identifies an obstacle but has not yet entered the ITE recognition blind area, if the ITE identifies that the obstacle has cleared the non-blind area, the ATS system outputs a clear mark of the identified obstacle and records and outputs the system time when it is cleared.

[0011] Furthermore, the ATS dispatch workstation in the control center displays the output as follows: When a train identifies an obstacle and enters the ITE blind spot or the vehicle body, the ITE system continues to lock the obstacle, and the ATS system outputs a first-level pop-up alarm to prompt the dispatcher. At the same time, the dispatch interface of the ATS dispatch workstation marks the output obstacle locked icon above the train number window.

[0012] Furthermore, the alarm tone also includes a set voice broadcast; After receiving the alarm information, the MMI also outputs the target distance to the obstacle in real time.

[0013] Furthermore, the acquired real-time images and the images at a set time before the obstacle is recognized are pushed to the OCC large-screen display output of the vehicle-mounted CCTV.

[0014] Furthermore, the process of video data upload and return scheduling is as follows: After the ATS dispatch workstation receives the alarm information sent by the ITE system when it identifies an obstacle, it executes the operation of retrieving the obstacle view data of the specified train through the alarm prompt box of the ATS system; The ITE system transmits obstacle view data to the ATS system through the internal interface protocol; The ATS system uploads the obstacle view data to the gateway computer according to the received retrieval command; The ATS dispatch workstation in the control center transmits obstacle image information of the designated train from the gateway computer.

[0015] The beneficial effects of the present invention are as follows: Based on the existing urban rail systems, after identifying an obstacle, ITE links the camera in the driver's cab to collect real-time view data. At the same time, after identifying an obstacle, ITE transmits the obstacle information to the ATS system. The ATS system forwards the alarm information to the ATS dispatching workstation through the alarm prompt box. The ATS dispatching workstation executes the view data dispatching operation through the alarm prompt box, based on the ATS system's call instructions, and realizes the return of view data based on the gateway computer. Active obstacle recognition under fully automatic operation of urban rail transit is realized. At the same time, the image of the identified obstacle can be returned under multi-system interaction, and output and displayed on the on-board display screen and OCC large screen. Based on multi-system linkage, it can also realize the linkage control of the train system after identifying the obstacle. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the dispatch interface of the ATS dispatch workstation marks an obstacle icon in front of the train.

[0023] When the train identifies an obstacle but has not yet entered the ITE identification blind area, if the ITE identifies that the obstacle has cleared the non-blind area, the ATS system outputs a clear mark for the identified obstacle and records and outputs the system time when it is cleared.

[0024] When a train identifies an obstacle and enters the ITE blind spot or the vehicle body, the ITE system continues to lock the obstacle, and the ATS system outputs a first-level pop-up alarm to prompt the dispatcher. At the same time, the dispatch interface of the ATS dispatch workstation marks the output obstacle locked icon above the train number window.
