Description

Technical Field

[0001] This invention relates to the field of rail transit communication technology, specifically to a method for opening and closing railway stations. Background Technology

[0002] In overseas railways, the only credential for a train to enter a section is the fulfillment of block conditions. For single-track bidirectional lines, the formation of block conditions requires the cooperation of the two stations protecting the section to complete block procedures, which are much more complicated than those in China. Since a block procedure can only serve as the departure credential for one train, block procedures must be completed for every trip between stations, resulting in a significant workload.

[0003] In actual operation, some freight lines have relatively low transport volumes, or some stations on the line have no passenger boarding or alighting needs. The primary function of these stations is for trains to pass through. For these stations, dedicated staff are still required to complete block closure procedures, inevitably leading to a waste of manpower. Furthermore, if the staff fails to complete the block closure procedures in a timely manner, it may cause train delays. Against this backdrop, a method is needed to quickly establish block closure relationships between two stations, thereby reducing operating costs and improving operational efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a railway station opening and closing method that can quickly establish a block relationship between two stations.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] A railway station opening and closing method includes the following steps: the station to be closed sends inquiry information to the two adjacent stations to confirm whether the station to be closed is permitted to close; after receiving permission, the station to be closed moves all mainline switches to the open mainline position and sends a station closing command; the interlocking system executes the station closing command after checking that the station closing conditions are met; the station to be closed sends station closing information to the two adjacent stations, so that the two adjacent stations respectively cut off their block relationship with the station, and at the same time establish a cross-station block relationship between the two adjacent stations.

[0007] Preferably, the interlocking system checks the station closure conditions, including: checking that there are no trains at the station to be closed and there is no current route operation; checking that the block signal of the station to be closed is in the restored state; and checking that the block signal between two adjacent stations is in the restored state and the large section is empty.

[0008] Preferably, the station closure method further includes interlocking protection after station closure, including locking the mainline turnouts of the station and keeping them locked after the station is closed, and prohibiting any other operations except for opening the station.

[0009] Preferably, the station opening method includes: the station to be opened sending inquiry information to the two adjacent stations respectively to confirm whether the station to be opened is allowed to open; after receiving a permission reply, the station to be opened sends a station opening command; after the interlocking system checks that the station opening conditions are met, it executes the station opening command; the station to be opened sends the station opening information to the two adjacent stations, so that the two adjacent stations can disconnect the block relationship and re-establish the block relationship with the station respectively.

[0010] Furthermore, the interlocking system checks the station opening conditions, including: checking that the block signal of the station to be opened is in the restored state; checking that the block signal between two adjacent stations is in the restored state; and checking the communication status between the station to be opened and the two adjacent stations.

[0011] Furthermore, the station opening method also includes: automatically disengaging the interlocking protection that was in place when the station was closed after the station is opened.

[0012] Preferably, the station status initialization method includes: when the station to be operated is initialized, if communication with two neighboring stations is normal and neither of the two neighboring stations has a station opening / closing status, the station to be operated is directly switched to the closed state. If it needs to be switched to the open state, manual operation is required.

[0013] Preferably, the station status initialization method includes: when the station to be operated is initialized, communication with two neighboring stations is normal, and the on / off status of the station to be operated recorded by the two neighboring stations is consistent, the station to be operated directly follows the received status to set the on / off status of the station to be operated.

[0014] Preferably, the station status initialization method includes: when the station to be operated is initialized, communication with two neighboring stations is normal, one of which has no status record of the station to be operated, while the other has a record, and the station to be operated directly follows the received status to set the opening and closing status of the station to be operated.

[0015] Preferably, the station status initialization method includes: when the station to be operated is initialized, communication is first established with any of the neighboring stations and the station has the on / off status of the station to be operated. The station to be operated then directly follows the received status to set the on / off status of the station to be operated.

[0016] Preferably, the station status initialization method includes: when the station to be operated is initialized, communication with two neighboring stations is normal, but the switch status sent by the two neighboring stations is inconsistent, the station to be operated is directly switched to the closed state, and both neighboring stations follow suit and record the station to be operated as closed.

[0017] Preferably, the station status initialization method includes: when the station to be operated is initialized, if the station's on / off status cannot be obtained, the station's on / off status is manually given; and only after the station is powered on and there is no on / off status for a certain period of time is the station's off button manually operated.

[0018] Furthermore, the station status initialization method includes: the duty officer needs to contact the two adjacent stations by phone in advance to see if the station close button can be operated.

[0019] Furthermore, the station status initialization method includes: both adjacent stations record the station to be operated as open, and the duty officer can operate the station close button to directly switch the station to open.

[0020] Furthermore, the station status initialization method includes: both neighboring stations record the station to be operated as closed, the duty officer does not need to operate the station close button, the station to be operated can remain in a stateless state, and the station will automatically return to the closed state after communication with the neighboring stations is established.

[0021] Furthermore, the station status initialization method includes: if the opening / closing status of the station to be operated recorded by two neighboring stations is inconsistent or both are in an empty state, the duty officer can operate the station close button, and the station to be operated will directly switch to the open state; after communication is restored, both neighboring stations will follow the station to be operated and record the station to be operated as open.

[0022] Preferably, the station to be closed and its adjacent stations exchange information via an inter-station interface.

[0023] The present invention has the following beneficial effects:

[0024] The station closure method of the present invention includes: first, the station to be closed sends inquiry information to the two adjacent stations to confirm whether closure is permitted; after receiving permission, the station to be closed moves all mainline switches to the open mainline position and sends a station closure command; then, the interlocking system executes the station closure command after checking that the station closure conditions are met; finally, the station to be closed sends station closure information to the two adjacent stations, so that the two adjacent stations respectively sever their block relationship with the station, and simultaneously establish a cross-station block relationship between the two adjacent stations. Using the station closure method of the present invention, stations with low workload can be closed directly, allowing adjacent stations to establish a block relationship across the station, thereby improving the efficiency of block procedures.

[0025] After a station is closed, a block is established between its two adjacent stations. Only one block procedure is required, and the train can travel between the two stations, reducing the original two block procedures between stations to one. At the same time, since the interval between stations is longer, the operating speed can be increased and the operation efficiency can be improved.

[0026] This invention proposes a new station closure technology that can flexibly close or open stations according to operational needs, reducing reliance on duty personnel and lowering operating costs.

[0027] This invention can also be used as an emergency train operation method in scenarios where trains cannot run in a section due to a block equipment failure at a station or a communication failure between two stations, thereby reducing the impact of the failure.

[0028] This invention checks the necessary interlocking conditions when the station opens and closes, ensuring the safety of train operation. Attached Figure Description

[0034] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the embodiments of the present invention. Please refer to the drawings to make the objectives, features, and advantages of the present invention more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for the purpose of assisting those skilled in the art in understanding and reading the content disclosed in the specification, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.

[0035] This embodiment proposes a station closure method that, for stations with low workload, eliminates the need for duty officers to complete block closure procedures and ensure normal train operation.

[0036] The overall plan for closing the station is as follows:

[0037] like Figure 1 As shown, a certain line has three stations: Station A, Station B, and Station C. Station B can be closed as needed, meaning no further operations can be performed at this station, equivalent to a section of track. The section from Station A to Station C forms a large section. When a train needs to travel from Station A to Station C, Station A and Station C coordinate to complete the block signaling procedure, thus achieving section block signaling. Conversely, the same applies when a train needs to travel from Station C to Station A. The closure of the block signaling between Station A and Station C will be referred to as cross-station block signaling. Station B does not require any block signaling-related operations.

[0038] When a train travels through a closed station, it is treated as a through operation. Therefore, all switches need to be in the mainline position. This operation needs to be manually performed by the duty officer before the station is closed.

[0039] To ensure operational safety, the closure and opening of stations must meet the corresponding interlocking conditions before they can be processed. Furthermore, after a station is closed, appropriate protective measures must be taken to ensure that trains can operate safely at the closed station.

[0040] The following sections detail the specific operational procedures and design schemes for station closure and opening:

[0041] Function F1 station closed:

[0042] like Figure 3 As shown, the operation procedure for closing station function F1.1 is as follows:

[0043] Step S1: The B station staff contacted the A and C station staff by phone to confirm whether B station allowed to be shut down.

[0044] Step S2: After obtaining consent from stations A and C, the station operator at station B needs to first move all mainline switches to the open position, and then press the station close button (PAS) on the operation display interface. After the interlocking system checks that the station closes and the conditions are met, it will close the station.

[0045] Step S3: After station B is closed, the station closure information is sent to stations A and C, so that stations A and C can respectively cut off the block connection with station B, and at the same time establish a cross-station block connection between stations A and C.

[0046] Function F1.2 Station Closure Inspection Conditions:

[0047] Station closures can only be performed on stations without operational activity. Therefore, it is necessary to check that the station being closed is free of trains and that no route operations are currently underway. Furthermore, since block signaling and other operations cannot be performed after a station is closed, it is also necessary to check that the block signaling is in a restored state before closure; otherwise, the block signaling connection with adjacent stations cannot be severed. After a station is closed, cross-station block signaling needs to be established between two adjacent stations; therefore, it is also necessary to check that the inter-station block signaling between the two adjacent stations is in a restored state and that the large section between them is clear. In summary, the specific inspection conditions for station closures should include the following:

[0048] Condition C1: The interval between Station A and Station B is empty;

[0049] Condition C2: The interval between Station B and Station C is empty;

[0050] Condition C3: Station A and Station B form a blocked directional opening, and their blocking circuit is in the restored state;

[0051] Condition C4: Station C and Station B form a blocked directional opening, and their blocking circuit is in the restored state;

[0052] Condition C5: The blocking circuits at both directional ports of Station B are in the restored state;

[0053] Condition C6: Both Station B and the mainline section are empty.

[0054] Condition C7: Station B has not established any type of path;

[0055] Condition C8: All turnouts on the main line of Station B are in the open position.

[0056] Function F1.3 Interlocking protection design after station closure:

[0057] Protective P1: Switch the mainline turnout of Station B to the locked state and maintain it;

[0058] For protection P2, except for Station B, all other operations are not allowed, such as block signaling, route control, and turnout switching.

[0059] F2 station is now open:

[0060] like Figure 4 As shown, the operation procedure for opening station function F2.1 is as follows:

[0061] Step S1: The duty officer at Station B contacts the duty officers at Stations A and C by phone to confirm whether Station B is allowed to open.

[0062] Step S2: After obtaining consent from stations A and C, station B pulls out the station open / close button on the operation display interface. After the interlocking system checks that the station opening conditions are met, it completes the opening of the station.

[0063] Step S3: After B station is opened, the opening information of this station is sent to A station and C station, so that A station and C station can cut off the blocking relationship and re-establish the blocking relationship with B station respectively.

[0064] Inspection conditions for opening station F2.2:

[0065] Condition C1: Station A and Station B form a blocked directional opening, and their blocking circuit is in the restored state;

[0066] Condition C2: Station C and Station B form a blocked directional opening, and their blocking circuit is in the restored state;

[0067] Condition C3: The blocking circuits at both directional ports of Station B are in the restored state;

[0068] Condition C4: Communication between Station A and Station B is normal;

[0069] Condition C5: Communication between Station C and Station B is normal.

[0070] Function F2.3: Disconnection of interlocking protection after station opening: After the station is opened, the interlocking protection associated with the station when it was closed will be automatically disconnected.

[0071] like Figure 2 As shown, station status initialization for function F3:

[0072] When initializing the station interlocking system, station status processing needs to be considered. Since both neighboring stations record the station status of this station, a comprehensive consideration based on inter-station communication status and the station status recorded by the two adjacent stations is required. The processing solution is as follows:

[0073] 1) When this station is initialized, if communication with two neighboring stations is normal and neither of the two neighboring stations has the switch status of this station, this station will directly switch to the closed state. If it needs to switch to the open state, manual operation is required.

[0074] 2) During the initialization of this station, communication with both neighboring stations is normal, and the power on / off status of this station is consistent as recorded by the two neighboring stations. This station directly follows the received status to set its power on / off status.

[0075] 3) During the initialization of this station, communication with two neighboring stations is normal. One station has no status record of this station, while the other station does. This station directly follows the received status to set the on / off status of this station.

[0076] 4) When this station is initialized, it first establishes communication with any of its neighboring stations and that station has the power on / off status of this station. This station then directly follows the received status to set its own power on / off status.

[0077] 5) During the initialization of this station, communication with the two neighboring stations is normal, but the switch status sent by the two neighboring stations is inconsistent. This station directly switches to the closed state, and both neighboring stations record this station as closed.

[0078] 6) If the station's on / off status cannot be obtained through the above scenarios during initialization, the on / off status can be manually provided. Considering that it takes time for this station to establish communication with neighboring stations, the PAS button should only be manually operated after the station has been powered on and has no on / off status for a certain period of time. Furthermore, the duty officer needs to contact the two neighboring stations by phone beforehand to confirm whether the PAS button can be operated.

[0079] ①If both neighboring stations record this station as open, the duty officer can press the PAS button to directly switch this station to the open state;

[0080] ② If both neighboring stations record this station as closed, the duty officer does not need to operate the PAS button. This station can remain in a stateless state and will automatically return to the closed state after establishing communication with the neighboring stations.

[0081] ③ If the two neighboring stations record the station's on / off status inconsistently or both are in an "no" status, the duty officer can operate the PAS button to directly switch the station to the on / off status; after communication is restored, both neighboring stations will follow the station's record to the on / off status.

[0082] Functional F4 Inter-station Interface Design:

[0083] Based on the design scheme for the station opening and closing functions, the three stations need to exchange information, as detailed in the table below:

[0084]

[0085]

[0086] The following details the implementation of the station closing and station opening functions:

[0087] To record the station's status, the following variables were designed:

[0088] OPEN: Records the open status of this station. It is a global variable that is set for each station. A value of 1 indicates that the station is open.

[0089] CLOSE: Records the closure status of this station. It is a global variable, set per station. A value of 1 indicates that the station is in a closed state.

[0090] BSKOPEN: Records the open status of this station. It is a local variable and is set according to the departure gate. A value of 1 indicates that the station is open.

[0091] BSKCLOSE: Records the closure status of this station. It is a local variable, set by departure gate. A value of 1 indicates that this station is in a closed state.

[0092] LZOPENBC: Records whether the neighboring station is open. It is a local variable, set by departure gate. A value of 1 indicates that the neighboring station is open.

[0093] LZCLOSEBC: Records whether the neighboring station is in a closed state. It is a local variable, set according to the departure gate. A value of 1 indicates that the neighboring station is in a closed state.

[0094] To determine whether the check conditions for station closure are met, the CLOSEJC variable was designed.

[0095] To determine whether the inspection conditions for opening a station are met, the OPENJC variable was designed.

[0096] In addition, the following variables were designed to handle the station state initialization:

[0097] NOSTATE: Time variable, records the time during which the station is in a state of no opening or closing. A value of 1 indicates that the grace period has expired and manual operation can be performed.

[0098] OPENGSEN: A value of 1 indicates that the condition for this station to be initialized to an open state following the two adjacent stations is met;

[0099] CLOSEGSEN: A value of 1 indicates that the condition for this station to be initialized to a closed state along with the two adjacent stations is met.

[0100] Combined with appendix Figure 2-4 This embodiment will be described as follows:

[0101] When station B is initialized, if it can obtain the initial open state following the two adjacent stations, then OPENGSEN is true, CLOSGEN is false, and OPEN is true, thus initializing the station to the open state.

[0102] When station B is initialized, if it can be initialized to the closed state along with the two adjacent stations, then CLOSEGSEN is true and OPENGSEN is false, and CLOSE is true, thus initializing this station to the closed state.

[0103] When station B is initialized, if it cannot obtain the initialization state along with the two adjacent stations, then OPENGSEN and CLOSGEN will not be true, and the station will be initialized to a state of no state. At this time, the duty officer can press the PAS button as needed for the operation, and if the associated interlocking condition check OPENJC is true, the station will be switched to the open state.

[0104] When station B is in the open state, if the duty officer presses the PAS button and the associated interlocking condition check CLOSEJC is true, the station will be switched to the closed state, and the closure information will be sent to other corresponding modules such as the turnout module, route module, and block module to restrict their operation.

[0105] When station B is in the closed state, if the duty officer pulls out the PAS button and the associated interlocking condition check OPENJC is successful, the station will be switched to the open state, and the open information will be sent to other corresponding modules such as the turnout module, route module, and block module, and their operation will no longer be restricted.

[0106] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
