Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-speed rail safety doors, and more particularly to a door column fault backup control system and method for high-speed rail safety doors. BACKGROUND

[0002] Unlike the fixed position of the subway platform screen door, the design of the high-speed rail safety door needs to be compatible with multiple different types of train models. Since the positions of the doors of different types of trains and the lengths of the carriages are different, the high-speed rail safety door needs to be designed to be extendable and movable to match different positions of the train models. If an individual door controller in the high-speed rail safety door system fails, the adjacent normal door columns may be occupied by the faulty door due to the movement of the position, thereby causing the failure to be transmitted to the entire system, so that the entire high-speed rail safety door system cannot operate normally.

[0003] Generally, all door controllers of the high-speed rail safety door are connected to the communication control bus to receive control instructions and move the door columns to the corresponding positions according to the control instructions. The commonly used communication control bus backup redundancy scheme of the existing high-speed rail safety door is generally as shown in Figure 1 All door controllers are connected to two sets of buses, and when one set of buses fails, the system can be switched to the other set of buses. This redundancy backup method only redundantly backs up the wiring, and actually does not redundantly back up the door controller failure.

[0004] The existing bus main backup method only improves the reliability of the system circuit, and does not solve the influence of individual door controller failure on the entire system. Because the failure of the individual door controller may seriously affect the realization of the overall function of the system due to the following reasons: the failure of the door controller causes the door column controlled by the door controller to be unable to normally extend and move, in which case the adjacent position is occupied, affecting the extension and movement of the adjacent door column, and sequentially transmitted to affect the extension and movement of more door columns.

In other instances, well-known structures and processes are not described in detail in order to avoid obscuring the description of the present application. Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features presented herein.

[0042] The purpose of the present application is to apply a backup solution in a high-speed rail safety door system, to redundantly backup the door controller failure, and to realize the function of the overall safety door system to continue to operate in the case of failure of an individual safety door controller, thereby improving the reliability and stability of the overall operation of the system.

[0043] Referring to Figure 2 , Figure 2is a topological graph of a door column fault backup control system of a high-speed rail safety door provided by an embodiment of the present application, the door column fault backup control system of the high-speed rail safety door comprising a plurality of door column fault backup control devices respectively arranged at a plurality of high-speed rail safety doors, the plurality of door column fault backup control devices being connected in series through serial interconnection lines and being respectively connected to a control bus. Each door column fault backup control device comprises a first door controller and a second door controller; each high-speed rail safety door comprises a first door body, a second door body, a first door column arranged in the first door body, and a second door column arranged in the second door body. At each high-speed rail safety door, the first door column is controlled by the first door controller to drive the first door body to move, and the second door column is controlled by the second door controller to drive the second door body to move.

[0044] In the embodiment, referring to Figures 3-4 , Figure 3 is a schematic diagram of a local door closing state of a high-speed rail safety door provided by an embodiment of the present application, Figure 4 is a schematic diagram of a local door opening state of a high-speed rail safety door provided by an embodiment of the present application. The first door column of a first door column fault backup control device (which can be named as module 1) can be numbered as 1L, and the second door column can be numbered as 1R. The first door column of a second door column fault backup control device (which can be named as module 2) can be numbered as 2L, and the second door column can be numbered as 2R. Similarly, the door columns numbered as 1L and 1R are a pair of adjacent door columns, the door columns numbered as 2L and 2R are a pair of adjacent door columns, the spacing between the adjacent door columns is very close, and in the door closing state, the adjacent door columns are close to each other, and in the door opening state, the adjacent door columns are spaced apart by a door opening distance. Each door column is controlled by a corresponding numbered door controller. In a normal working condition, each door column can move according to a control instruction and feedback a normal state to a control center. In a fault condition, an individual door column cannot move according to the control instruction and feedback an abnormal state. When the door controller fails, a linkage control mechanism of adjacent door columns is started, the failed door column is connected with the adjacent door columns, and the adjacent door columns are used to assist the failed door column to realize corresponding extension and movement.

[0045] At each high-speed rail safety door, the first port of the first door controller and the first port of the second door controller are connected to the control bus, the second port of the first door controller and the second port of the second door controller are connected to the first node, the third port of the first door controller and the third port of the second door controller are connected to the second node, and each door column fault backup control device is connected to adjacent door column fault backup control devices through the first node and the second node respectively.

[0046] In the embodiment, referring to Figure 5 , Figure 5 is a schematic diagram of communication wiring connection in each door column fault backup control device provided by an embodiment of the present application, two door controllers in the module are connected through internal interaction lines to realize information interaction between the door controllers.

[0047] Each door column fault backup control device further comprises a first switch and a second switch, the normally closed end of the first switch and the normally closed end of the second switch are connected to a power supply, the first normally open end of the first switch and the first normally open end of the second switch are connected to the first door controller, and the second normally open end of the first switch and the second normally open end of the second switch are connected to the second door controller.

[0048] In the embodiment, referring to Figure 6 , Figure 6 The door controller power supply control diagram in each door column fault backup control device provided by the embodiment of the application, the power supply control switch of the door controller is in a default on state when powered on, and through the switch, each door controller in the module can turn off the power supply switch of another door controller, so that when a door controller in the module fails, the normal door controller can power off or restart the failed door controller.

[0049] Each door column fault backup control device further comprises a first brake device and a second brake device, the first brake device is connected to the first door controller and the second door controller respectively, and the second brake device is connected to the first door controller and the second door controller respectively.

[0050] In the embodiment, referring to Figure 7 , Figure 7 The brake control switch diagram in each door column fault backup control device provided by the embodiment of the application, the door controller can control the brake of the door column and the adjacent door column, and when the door controller is powered off, the brake device of the door column is controlled by the adjacent door controller. This design facilitates the brake system to be controlled by the adjacent door column when the door column fails.

[0051] Each door column fault backup control device further comprises a linkage buckle, the linkage buckle is connected to the first door controller and the second door controller respectively, and the linkage buckle is used for buckling the first door body and the second door body.

[0052] In the embodiment, referring to Figure 8 , Figure 8 The linkage buckle diagram in each door column fault backup control device provided by the embodiment of the application, the linkage buckle is used for connecting two adjacent door columns together so that they can move together. Under normal circumstances, the linkage buckle is opened and not used, and the two door columns in the module move independently. When a fault occurs, the linkage function of the linkage buckle is used to move the two door columns together. The two door controllers of a module can control the linkage buckle linkage, so that when one door controller fails, the normal door controller can control the linkage buckle.

[0053] The application further provides a door column fault backup control method of a high-speed rail safety door, which is implemented by using the door column fault backup control system of the high-speed rail safety door according to any one of the above.

[0054] S1, driving the first door column by the first door controller to drive the first door body to move, and driving the second door column by the second door controller to drive the second door body to move.

[0055] In this embodiment, when a single door column fails, the function movement of the single door column is realized by the adjacent door column, the adjacent door columns are backup for each other, each pair of adjacent door columns is grouped, and each pair of adjacent door columns is controlled as a module. When a single door column in the module fails, the working mode is automatically switched to be assisted by another normal door column in the module to move the abnormal door column, and the change of the working mode in the single module does not affect the control of other modules. The switching of the backup working mode in the failure is completed in the module, and has no significant influence on other control parts outside the module. The two adjacent door controllers in each door column backup control device realize the backup function for each other in the module.

[0056] S2, when the first door controller fails or the second door controller fails, the backup working mode in the failure is switched to. Step S2 includes steps S21-S22.

[0057] S21, if the first door controller fails, the first door controller stops driving the first door column, the second door column is driven by the second door controller to drive the second door body to move, the first door body and the second door body are buckled by the linkage buckle, the second door body is pushed by the first door body to assist the first door column to move to a preset first position, then the linkage buckle is released, and the second door column is driven by the second door controller to drive the second door body to move.

[0058] In this embodiment, referring to Figure 9 , Figure 9 The step diagram for assisting the 1L door column to open the door by the adjacent 1R door column when the 1L door column fails is provided in an embodiment of the application. The 1L door column releases the brake and is linked with the 1R door column, the 1R door column moves to the left, pushes the 1L door column to move to the door opening position of the 1L door column, then the two door columns release the linkage, and the 1R door column moves to the right to the door opening position of the 1R door column. In this way, the two adjacent door columns are moved from the door closing position to the corresponding door opening position.

[0059] S22, if the second door controller fails, the second door controller stops driving the second door column, the first door column is driven by the first door controller to drive the first door body to move, the first door body and the second door body are buckled by the linkage buckle, and the second door body is pushed by the first door body to assist the second door column to move to a preset second position. Then, the linkage buckle is released, and the first door column is driven by the first door controller to drive the first door body to move.

[0060] In this embodiment, this step is similar to step S21, the adjacent door pillar is first moved to be close to the faulty door pillar to implement linkage, the faulty door pillar is moved to the expected position by the adjacent door pillar, and then the adjacent door pillar is moved to the expected position thereof.

[0061] In addition, each door pillar fault backup control device needs to be able to monitor whether the working state of the door pillar is normal at any time, and needs to be switched into a fault backup working mode when the working state is abnormal. After the module is powered on, it defaults to enter a normal working mode, and when running in the normal working mode, the door controller regularly performs a state self-check query, and if the query result is normal, a heartbeat signal is sent to the adjacent door controller through an internal interaction interface. The door controller considers that another adjacent door controller in the same module is faulty when a fault signal is received or the heartbeat signal is not received within a timeout period, and then can be switched to a backup working mode in a fault state. Referring to Figures 10-11 , Figure 10 A self-check flowchart in a normal working state provided by an embodiment of the present application is shown in Figure 11 A flowchart for monitoring the state of an adjacent door controller in a normal working state provided by an embodiment of the present application is shown in FIG. 5. The steps for switching the door pillar fault backup control device from the normal working mode to the backup working mode in a fault state are shown in Figure 12 , Figure 12 A flowchart for switching the door pillar fault backup control device from the normal working mode to the backup working mode in a fault state provided by an embodiment of the present application is shown in FIG. 6.

[0062] After the door pillar fault backup control device is powered on, it defaults to enter a normal working mode, in which two adjacent door controllers in the module each self-performs drive control to complete the movement of the door pillar. Referring to Figure 13 , Figure 13 A flowchart for the normal working mode of the door pillar fault backup control device provided by an embodiment of the present application is shown in FIG. 5.

[0063] When a single door controller fault is detected in the door pillar fault backup control device, it is switched into a backup working mode in a fault state, in which the faulty door controller stops driving, and the other normal door controller in the door pillar fault backup control device drives the abnormal door controller to move to the expected position. Referring to Figure 14 , Figure 14 A flowchart for the backup working mode in a fault state of the door pillar fault backup control device provided by an embodiment of the present application is shown in FIG. 6.

[0064] Those skilled in the art can understand that all or part of the steps of various methods in the above embodiments can be completed by instructions or by controlling relevant hardware by the instructions, and the instructions can be stored in a computer readable storage medium and loaded and executed by a processor. To this end, the embodiments of the present application provide a storage medium, wherein a plurality of instructions are stored, and the instructions can be loaded by a processor to execute the steps in any high-speed rail safety door door column fault backup control method provided by the embodiments of the present application.

[0065] The storage medium can include a read-only memory (ROM), a random access memory (RAM), a magnetic disk or an optical disk, etc.

[0066] Since the instructions stored in the storage medium can execute the steps in any high-speed rail safety door door column fault backup control method provided by the embodiments of the present application, the beneficial effects of any high-speed rail safety door door column fault backup control method provided by the embodiments of the present application can be achieved, which are described in detail in the foregoing embodiments and will not be repeated here.
