Description
Technical Field
The invention relates to the technical field of urban rail transit, in particular to a control method, a device, equipment and a medium for gap detection.
Background
As urban rail transit gradually becomes an important transportation mode for people to go out, people pay more attention to the safety of urban rail transit. For example, in order to ensure safety of trains and passengers entering and exiting the station, a screen door is installed at the station. The platform and the train operation area are separated by the shielding door, so that passengers can be prevented from falling onto the train track due to accidents, and the safety of the passengers is protected.
However, there is currently a gap between the screen door and the train door that can accommodate small persons or children. If a child or a small person is present in the gap after the train starts to leave, a major accident may be caused. Therefore, in order to ensure that no obstacle exists in the gap between the train door and the screen door when the train is ready to be launched, obstacle detection needs to be performed on the gap.
The existing gap detection technology cannot perform signal interaction with a Computer Interlocking (CI) system, once an obstacle is found, a worker needs to open a shielding door immediately for operation treatment, and the vehicle is dispatched after the worker finishes the treatment. The method for carrying out operation treatment by manually opening the shielded door has the advantages of longer operation treatment time and lower operation treatment efficiency.
Therefore, how to improve the operation handling efficiency by controlling the gap detection system becomes an urgent technical problem to be solved.

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It will be apparent to one skilled in the art that the present invention may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.
In order to ensure the safety of passengers, a screen door is usually provided at the platform to separate the platform from the train's operating area. However, in the actual operation process, because a gap exists between the train door and the shielding door, the condition that objects are clamped between the train door and the shielding door is easy to occur, and potential safety hazards exist.
Because the signal of the train is not opened, most of the existing operation handling means are that the staff at the platform confirms whether the object clamped by the person exists at the gap between the train door and the shield door, if no obstacle exists at the gap, the staff at the operation center can be informed to command the train to dispatch, if the obstacle exists at the gap, the staff at the platform can only handle the object, and after the staff finishes the handling, the staff at the operation center is informed to command the train to dispatch.
The operation method which needs manual monitoring and obstacle disposal has long operation disposal time and low operation disposal efficiency.
Therefore, the embodiment of the invention provides a control method for gap detection, which can automatically detect whether an obstacle exists at a gap between a train door and a screen door, and can automatically open the train door when the obstacle exists so as to eliminate the obstacle, shorten operation treatment time and improve operation treatment efficiency.
A control method, apparatus, device, and medium for gap detection according to embodiments of the present invention are described in detail below with reference to the accompanying drawings. It should be noted that these examples are not intended to limit the scope of the present disclosure.
A flow signaling diagram of a control method of gap detection according to an embodiment of the present invention is described in detail below with reference to fig. 1 and 2.
For better understanding of the present invention, the following describes the control method for gap detection according to an embodiment of the present invention with reference to fig. 1, and fig. 1 is a flow signaling diagram illustrating the control method for gap detection according to an embodiment of the present invention.
In one embodiment of the invention, the VOBC is used as an on-board controller of the train, and when receiving the locking signals (or closing and locking signals of the car door and the screen door) fed back by the target train and the CI system, the VOBC sends a start signal to the CI system to command the CI system to control the gap detection system to perform gap detection.
When the CI system controls the gap detection system to detect and receives a gap detection result fed back by the gap detection system, the VOBC controls the state of the target train based on the gap detection result.
In one embodiment of the present invention, if the gap detection result fed back to the VOBC by the CI system is no obstacle, the VOBC can control the target train to normally depart.
In the embodiment of the invention, the VOBC can obtain the gap detection result between the vehicle door and the shield door of the target train through the signal interaction between the CI system and the VOBC, and the state of the target train is controlled through the obtained gap detection result, so that whether an obstacle exists between the vehicle door and the shield door of the target train or not does not need to be monitored by a worker, the operation treatment time of the train can be shortened, and the operation treatment efficiency of the whole train is improved.
In one embodiment of the present invention, as shown in fig. 2, fig. 2 is a flow signaling diagram illustrating a control method of gap detection according to another embodiment of the present invention.
And if the gap detection result fed back to the VOBC by the CI system is that an obstacle exists, the VOBC can control the target train and the shielding door to open the door again.
When the target train and the shielding door are opened again, the VOBC sends a stop signal to the CI system, so that the CI system controls the gap detection system to stop gap detection. And after the VOBC delays for a preset time interval, the target train and the shielding door are detected so as to receive the locking signals of the train door and the shielding door of the target train again.
As an example, the preset time interval may be set in consideration of a control period during which the CI system controls the gap detection system to stop operating, a period during which the gap detection system stops operating, a communication period of the VOBC with the CI system, and a period during which the CI system receives feedback information of the gap detection system. Wherein the communication cycle of the VOBC with the CI system can be considered in terms of the maximum communication failure time.
When the door and the shield door of the target train are opened again, if people are clamped between the door and the shield door of the target train, the clamped passengers can enter the train or the platform section by opening the door again, and then the purpose of eliminating obstacles is achieved.
After the VOBC receives the locking signals of the doors and the shield doors of the target train again, the starting signals are sent to the CI system again. At this time, the CI system may determine whether a time length between the last time the stop signal is received and the time the start signal is received (i.e., a stop time length for the gap detection system to stop the gap detection) satisfies a preset time length, and if the preset time length is satisfied, the CI system may respond to the start signal to control the gap detection system to perform the gap detection.
In the embodiment of the invention, if the VOBC obtains the gap detection result that the obstacle exists, the door and the screen door of the target train are controlled to be opened again, so that the passenger can automatically eliminate the obstacle caused by the passenger (for example, the passenger can take back the backpack clamped at the gap), the door and the screen door do not need to be opened manually by the staff, the operation handling time of the train can be shortened, and the operation handling efficiency is improved.
As an example, the preset duration may be set in consideration of a control duration for the CI system to control the gap detection system and a stop duration for the gap detection system.
In one embodiment of the invention, if the CI system receives a start signal and a stop signal from the VOBCs of different trains, respectively. That is, the CI system receives the start signal transmitted by the VOBC of the first train and receives the stop signal transmitted by the VOBC of the second train, and at this time, the CI system preferentially responds to the stop signal transmitted by the VOBC of the second train to control the gap detection system to stop the gap detection.
When the CI system detects that the stop duration of the gap detection system for stopping the gap detection meets the preset duration, the first train is used as a target train, and the gap detection system is controlled to perform gap detection in response to a starting signal of the first train (the target train).
The CI system transmits the gap detection result fed back by the gap detection system to the VOBC so that the VOBC performs state control of the train.
In the embodiment of the invention, the CI system preferentially responds to the stop signal, controls the gap detection system to stop gap detection, and responds to the start signal after the preset time length, so that the CI system can effectively avoid that the last gap detection result is fed back to the VOBC by mistake, the VOBC carries out misoperation on the target train, and the safety and the accuracy of operation treatment are improved.
In one embodiment of the present invention, if the gap detection result is no obstacle, the VOBC controls the target train to normally depart.
In another embodiment of the present invention, if the gap detection result received again by the VOBC still indicates that there is an obstacle, the VOBC will continue to control the doors and the platform doors of the target train to open the doors again, so as to repeat the above control method of gap detection as shown in fig. 2, which is not described herein again.
In another embodiment of the present invention, if the VOBC continuously receives the gap detection result that the receiving time of the obstacle meets the preset threshold, the VOBC may send a detection request to the TIAS system, the TIAS performs fault detection on the target train, and if the detection result is that the gap detection system is misinformed, the TIAS may remotely control the target train to normally depart through the VOBC.
If the detection result shows that an obstacle exists (for example, the backpack is clamped at a train door gap and is difficult to take out), the TIAS informs the staff of manual treatment. For example, a prompt message for turning on a key in a manual driving mode is displayed by using a multimedia Interface (MMI), the driving mode of the target train is changed into the manual driving mode by waiting for a driver to turn on the key in the manual driving mode, and the driving mode of the target train is upgraded into a full-automatic driving mode after a platform operator manually turns on or off a vehicle door and processes an obstacle.
In one embodiment of the present invention, the VOBC sends a stop signal to the CI system if the tail of the target train has completely left the platform, and the CI system controls the gap detection system to stop gap detection.
In one embodiment of the present invention, if the VOBC detects that the communication with the CI system is failed and/or that an obstacle is present in the gap detection result received during the time when the target train exits the platform, the target train is controlled to stop operating.
As an example, after the doors and the platform doors of the target train are opened again, if the VOBC detects that a communication failure occurs in the communication with the CI system, the VOBC cannot control the doors and the platform doors of the target train to be closed. At this time, the platform operator is required to close the car door and the screen door, and at this time, the VOBC does not send a start signal to the CI system any more, so that the CI system controls the gap detection system to perform gap detection. But the platform staff ensures that no obstacle exists between the vehicle door and the shield door of the target train.
As another example, if the VOBC detects a communication failure with the CI system, an obstacle is present between the doors and the platform doors of the target train by default, and departure of the target train is prohibited. And the VOBC sends an emergency braking non-release instruction to the target train, key prompt information for opening a manual driving mode is displayed by using the MMI, a request for applying departure is sent to the control center, and a worker of the control center remotely confirms normal departure of the target train or changes the driving mode of the target train into a non-full-automatic driving mode, so that departure is manually carried out.
In one embodiment of the present invention, the gap detection system is controlled to stop gap detection if the CI system detects a communication failure with the VOBC. So as to prevent the CI system from misusing the gap detection result of the previous time when the gap detection result fed back by the gap detection system is received next time.
In the embodiment of the invention, if communication failure occurs between the VOBC and the CI system, the target train is emergently braked, and the driving mode is changed into a non-full-automatic driving mode, so that accidents can be effectively avoided, and the safety factor of safe driving of the train can be improved.
In one embodiment of the present invention, if the CI system detects that the screen door is open and closed when the platform is idle and empty, the CI system does not control the gap detection system to perform gap detection.
In an embodiment of the invention, when the number of times of re-opening the doors and the screen doors of the target train meets the preset number of times, if the VOBC still does not receive the locking signals of the doors and the screen doors of the target train, that is, the doors or the screen doors of the target train are still not locked, the VOBC controls the target train to stop at the platform, keeps a traction state, sends a door non-closing fault to the TIAS, and waits for manual processing. At this point, the VOBC no longer sends a start signal to the CI system.
It should be understood that, in the embodiment of the present invention, no limitation is imposed on the preset number of times for the doors of the target train and the shield door to be re-opened, and the preset number of times for the doors of the target train and the shield door to be re-opened may be set according to actual requirements.
In the embodiment of the invention, by setting the preset times of the target train and the shield door for re-opening, when the train door and the shield door meet obstacles which are difficult to eliminate, workers can be informed to process the obstacles in time, so that repeated re-opening of the train door and the shield door is effectively avoided, the operation processing time can be shortened, and the operation processing efficiency can be improved.
