An interlocking system automatic route logic processing method

Abstract

This invention provides an automatic route logic processing method for an interlocking system. The system includes an automatic route construction module, an automatic route exit module, and an automatic route inspection module. The automatic route construction module receives an execution signal to enter the automatic route construction step, and the automatic route exit module receives an exit signal to enter the automatic route exit step. During automatic route mode operation, the automatic route signal inspection module continuously runs the automatic route detection step. This method aims to establish a control mode for established train routes. Once a train route enters this mode, the route will not automatically unlock due to train operation. After the train clears the route, the route start signal can automatically reopen if the signal opening conditions are met, without requiring the operator to re-arrange the route.

Description

Technical Field

[0001] This invention relates to the field of train route control, and more particularly to a logic processing method for an automatic route mode of an interlocking system. Background Technology

[0002] Due to the needs of station operations, line junctions without interlocking switches on the main railway line need to be incorporated into nearby interlocking stations for centralized control to save on signal equipment costs and infrastructure expenses. This centralized control method is called centralized interlocking or regional interlocking. During normal line operation, trains do not need to stop at the line junctions; therefore, train operations in both the down and up directions at the line junctions are through operations, meaning that the entry and exit signals of the line junctions are simultaneously open to improve operational efficiency.

[0003] When there are a large number of centrally controlled train signals and train operations are frequent, station staff need to process several train routes that are connected in the same direction multiple times. This increases the workload of the staff and also increases the risk of incorrect route processing, affecting train operation safety.

[0004] Considering the safety of train route control and the flexibility of on-site operations, it is not simply a matter of automatically triggering the required train routes simultaneously to meet the need for automatic route processing. There is a need to provide an effective means to manage trains that can both ensure train operation safety and meet operational flexibility requirements. In the existing technology, there is no method involving the automatic route logic processing of the interlocking system. Summary of the Invention

[0005] This invention provides an automatic route logic processing method for an interlocking system. This method aims to overlay an automatic route control mode onto an established train route, ensuring that the train route is locked after a train has passed and the signal can be automatically released. The corresponding system includes: an automatic route construction module, an automatic route exit module, and an automatic route checking module.

[0006] The automatic route construction module receives an execution signal and enters the automatic route construction step; the automatic route exit module receives an exit signal and enters the automatic route exit step; and the automatic route signal inspection module runs to implement the automatic route detection step.

[0007] The automatic route construction step and the automatic route exit step enable the operation and exit of the automatic route mode for train routes. During the operation of the automatic route mode, the automatic route detection step continues to run, enabling automatic restart in case of failure. The automatic route construction step includes the following steps in sequence: S1. Establishing a train route, with the route locked and the signal open; S2. Setting the automatic route mode; S3. The automatic route remains unlocked, and the signal is automatically opened. The automatic route exit step is S4. Canceling the automatic route mode. The automatic route detection step is S5. After the automatic route signal fails, the signal is automatically reopened. During the operation of the automatic route module, the automatic route module operates independently of the automatic route exit module and the automatic route signal inspection module.

[0008] Preferably, the beginning and end of the train route are set as signals. Depending on the nature of the train operation, the signal indicating that the train is entering the station is called the entry signal, and the signal indicating that the train is leaving the station is called the exit signal.

[0028] The automatic route signal faults include: track section faults, turnout derailment, and broken signal filaments.

[0029] Compared with the prior art, the present invention has the following beneficial effects:

[0030] 1. The automatic route processing method of the interlocking system is based on an existing route that has been established and whose starting signal is open. An automatic route control mode is superimposed on the route. This mode is used to control the route to be locked after the train clears the route. At the same time, the signal is automatically opened when the opening conditions are met. This allows the train route to be dynamically controlled according to the train's running conditions. This can greatly reduce the labor intensity of station duty officers in repeatedly arranging routes and the probability of operational errors, thereby improving train operation safety.

[0031] 2. The automatic route mode operates independently of the automatic route exit module and the automatic route signal check module. It does not affect the existing signal closing timing and locking check control logic, does not reduce the safety of the existing signal control logic, and ensures driving safety.

[0032] 3. An automatic route button is set up, which can be set and canceled at any time according to the needs of station operation. This solves the shortcoming of the interlocking system in the existing technology that directly triggers the route after power-on. It supports the flexible selection of setting and canceling the automatic route mode according to the actual operation situation, thus improving the flexibility of operation.

[0033] 4. The automatic route logic processing method of the interlocking system has fault tolerance processing for possible faults in the trackside signaling equipment. When a fault occurs in the signaling infrastructure (such as: track section fault, turnout derailment, signal filament breakage), the train signal will not be automatically opened, and the train cannot pass the closed signal. After the fault is restored, the interlocking system can automatically restart the automatic route logic control without manual intervention, so that the signal is automatically opened, enhancing the fault tolerance and scientific nature of the system.

[0041] The technical content, structural features, objectives and effects of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0042] This invention provides an automatic route logic processing method for an interlocking system. Figure 1 This is a schematic diagram of the five stages of the present invention. (See diagram below.) Figure 1 As shown, the system corresponding to this method includes: an automatic route construction module, an automatic route exit module, and an automatic route inspection module; wherein, the automatic route construction module receives an execution signal to enter the automatic route construction step; the automatic route exit module receives an exit signal to enter the automatic route exit step; during the operation of the automatic route mode, the automatic route signal inspection module continuously runs the automatic route detection step.

[0043] During operation, the automatic route module operates independently of the automatic route exit module and the automatic route signal check module. It does not affect the existing signal closing timing and locking check control logic, does not reduce the safety of the existing signal control logic, and ensures driving safety.

[0044] The automatic route construction step involves overlaying an automatic route control mode onto an existing train route using an automatic route construction module. This ensures that the train route is locked after a train passes and the signal is automatically reopened. The automatic route exit step cancels the automatic route mode. Simultaneously, an automatic route check module is used to perform an automatic route detection step during automatic route mode operation. If an automatic route signal malfunctions, the system automatically reopens after a signal failure and signal recovery.

[0045] Specifically, the train route consists of a train route start point, a train route end point, a track section, and turnouts. The train route start point and train route end point are equipped with signals. Depending on the nature of the train operation, the signal indicating the train's entry into the station is called an entry signal, and the signal indicating the train's departure from the station is called a departure signal.

[0046] Furthermore, all train routes starting from the station entry signal constitute a train reception operation, which is a train operation to the track; all train routes starting from the station exit signal constitute a train departure operation, which is a train operation to the track. The automatic route mode logic processing method is applicable to both train reception and train departure operations.

[0047] For train routes, if the start and end points of the route are signals in opposite directions, the section from the start to the end of the route is defined as the inner section of the route terminal, and the section from the end of the route to the blocking signal (which is in the same direction as the signal at the start of the route) is defined as the outer section of the route terminal. If the start and end points of the route are signals in the same direction, the section from the start to the end of the route is defined as the inner section of the route terminal, and the next section inside the signal at the route terminal, facing the direction of train travel, is defined as the outer section of the route terminal, which is not within the scope of the train route.

[0048] In a preferred embodiment, the train route start and train route end each include a train button for arranging the route, the track section is all the sections on the train's running path, the turnout is used to determine the position of the train, and each turnout includes a track section. By pressing the train route start button and the train route end button, the train route can be arranged.

[0049] The automatic route construction steps are as follows:

[0050] S1. Establish a train route, with the route locked and the signal open.

[0051] Specifically, such as Figure 3 As shown, after receiving the execution signal, the system checks whether the command signals at the beginning and end of the train route are valid, whether the filaments of the turnout, section, and route beginning signals are in valid working condition, and whether there is a no-opposing-route signal. Once the aforementioned signal detections are completed, if the corresponding signal is valid, the train route is established; if any signal is invalid, the process ends.

[0052] Once a train route is established, the validity of the starting and ending signals of the train route is checked. If the corresponding signals are valid, the section of the train route within the terminal is locked. If any signal is invalid, the process ends.

[0053] After a section of the train route is locked in the train route terminal, the validity of the section route locking signal in the train route terminal is checked. If the corresponding signal is valid, the train route start signal is opened; if the signal is invalid, the process ends.

[0054] S2. Set automatic route mode.

[0055] Specifically, such as Figure 4 As shown, after all steps in S1 are completed, the system checks whether the automatic route button processing command and pull-out command for the train route are valid signals, whether the train route start signal opening is valid, and whether the automatic route mode signal for the current route in the previous operation cycle is invalid. If the corresponding conditions are met, the train route is in automatic route mode; if any signal is not met, the process ends.

[0056] Once the train route is set to automatic route mode, the system checks for the presence of an automatic route mode cancellation or train route cancellation command signal. If no such command is found, the train route enters the automatic route control mode holding phase. If either cancellation command signal is present, the process ends.

[0057] Setting the automatic route mode refers to the station operator pressing the automatic route button on the human-machine interface of the computer interlocking system for the route that requires automatic route mode setting. The automatic route button is a two-position, non-automatic reset button with both pressed and pulled-out states. When the station operator presses the automatic route button, the automatic route mode is set for the corresponding route. The button is highlighted in red when pressed, indicating that the current route is in automatic route mode.

[0058] This automatic route button can be set and canceled at any time according to the station's operational needs, which solves the shortcoming of the existing technology where the interlocking system directly triggers the route after power-on. It supports flexible selection of setting and canceling the automatic route mode according to the actual operation situation, thus improving the flexibility of operation.

[0059] S3. Lock the automatic route mode; the signal will be automatically released.

[0060] Specifically, such as Figure 5 As shown, after the train route enters the automatic route control mode holding phase, the system detects whether the signal at the end of the train route is in the same direction or in the opposite direction as the signal at the beginning.

[0061] Specifically, when the signals are in the same direction, the system checks whether the normal cross-pressure signal and the clearing signal of the last section of the train route are valid, whether the signal of the next section of the route being occupied by the train is valid, and whether the train route terminal signal is valid. If the corresponding signals are valid, the train clearing section record is valid. If any signal is invalid, the process ends.

[0062] When the signal is a reverse signal, the system checks whether the normal cross-pressure signal and the clearing signal of the last section of the train route are valid, whether the signal of the outer area of ​​the route terminal being occupied by the train is valid, and whether the signal of the train route terminal is valid. If the corresponding signal is valid, the train clearing section record is valid. If any signal is invalid, the process ends.

[0063] After the train exit section record is valid, check whether the train route start signal is closed. If closed, the train exit section record enters the holding phase; if the signal is valid, the process ends.

[0064] After the train exit section recording enters the holding phase, the validity of the train exit section recording holding signal is checked, the validity of the train route start signal check enable signal is checked, and the validity of the train route start signal open check enable signal is checked. If the corresponding signal is valid, the train signal is automatically reopened. If any signal is invalid, the process ends.

[0065] After the automatic restart of the train signal is valid, the validity of the automatic restart signal of the train route is checked. If the corresponding signal is valid, the train route start signal is automatically opened, and the train enters the automatic route control mode. If the signal is invalid, the process ends.

[0066] The automatic route exit steps are as follows:

[0067] S4. Cancel automatic route mode.

[0068] Specifically, such as Figure 6As shown, the system checks whether an automatic route mode cancellation command signal has been received. If such a signal is received, the train route signal check control logic ceases to be valid, thus allowing the train route unlocking logic to operate normally. The train exit section record remains invalid, thereby invalidating the automatic reopening of the train route, and the train route signal will no longer be automatically opened. If no such signal is received, the system will not enter this mode.

[0069] The system checks whether a train route cancellation command signal has been received. If the corresponding signal is received, the train route unlocking logic operates normally, unlocking the train route and eliminating its existence. At the same time, the automatic route mode superimposed on the train route is also canceled.

[0070] In the case of receiving an automatic route mode cancellation command, only the mode superimposed on the train route is cancelled, the train route itself still exists, and the signal check control logic and train route unlocking logic both return to normal. In the case of receiving a train route cancellation command, both the train route mode and the train route are cancelled, and the train route no longer exists.

[0071] Step S401 includes:

[0072] con33: Detected that an automatic route mode cancellation command has been received;

[0073] When condition con33 is met, the automatic route mode is disabled, i.e., con16 is disabled; simultaneously:

[0074] The train route signal check control logic is no longer valid, thus causing the train route unlocking logic to operate normally; the train exit section record con26 is invalid, which in turn makes the automatic reopening of the train route con29 invalid, and the train route signal no longer automatically opens.

[0075] 21. The automatic route logic processing method for an interlocking system according to claim 20, characterized in that step S402 includes:

[0076] con34: The system has received a train route cancellation order;

[0077] When condition con34 is met, the automatic route mode is disabled, i.e., con16 is disabled; simultaneously:

[0078] The train route signal check control logic is no longer valid, thus causing the train route unlocking logic to operate normally; the train exit section record con26 is invalid, which in turn makes the automatic reopening of the train route con29 invalid, and the train route signal no longer automatically opens.

[0079] The automatic route detection steps are as follows:

[0080] S5. Automatic route signal fault detection.

[0081] Specifically, such as Figure 7 As shown, if the detection train route has no cross-voltage signal, the detection train route start signal is a closed signal, and the detection train route automatic route mode valid signal is present, then a signal fault is determined to have occurred; otherwise, the fault detection ends.

[0082] After confirming a signal fault, the train signal must be automatically restarted. This involves checking whether the turnouts in the train route are valid working signals, whether there are no opposing route signals, whether the train exit section record is valid, whether the train route start signal check is enabled, and whether the automatic route fault record is valid. If all these conditions are met, the train signal will be automatically restarted. If not, the process will end.

[0083] The steps S1 include the following steps in sequence: Step S101: Establishing a train route; Step S102: Locking the inner section of the route terminal; Step S103: Opening the train route start signal.

[0084] In a specific embodiment, steps S101, S102, and S103 are performed according to the following process:

[0085] Step S101 executes the following detection process:

[0086] con1: Detects the validity of the train route start command;

[0087] con2: The train route terminal command is valid;

[0088] con3: Detects whether the turnouts in the train route are in the required positions for the route;

[0089] con4: The train's route is not occupied by any train.

[0090] con5: No other hostile routes that are in conflict with this train's route have been established;

[0091] con6: Check that the filament of the red light at the starting signal of the train route is intact.

[0092] When conditions con1, con2, con3, con4, con5, and con6 are simultaneously met (regardless of their order), a train route is established.

[0093] After step S101 is completed, proceed to step S102 to execute the following detection process:

[0094] con7: The train route start record is valid;

[0095] con8: The train route terminal record is valid.

[0096] When conditions con1, con2, con3, con4, con5, con6, con7, and con8 are simultaneously met (regardless of their order), the section route within the train route terminal is locked.

[0097] When the section within the train route terminal is in the locked-out phase, the above conditions con1, con2, con3, con4, con5 and con6 are no longer detected, while con7 and con8 remain valid.

[0098] After step S102 is completed, proceed to step S103 and execute the following detection process:

[0099] con9: Detects track section route locking within the train route terminal.

[0100] When conditions con3, con4, con5, con6, and con9 are simultaneously met (regardless of their order), the train route start signal is opened.

[0101] Step S2 includes, in sequence: S201, activating the automatic route control mode; and S202, maintaining the automatic route control mode.

[0102] In a specific embodiment, steps S201 and S202 are performed according to the following process:

[0103] After all steps in S1 are completed, proceed to step S201 and execute the following detection process:

[0104] con10: The automatic route detection button for train route is valid;

[0105] con11: The automatic route detection button pull-out command is invalid;

[0106] con12: Detects the opening of the train route start signal;

[0107] con13: Detects that the automatic route mode of the current route was invalid in the previous operation cycle.

[0108] When conditions con3, con10, con11, con12, and con13 are met simultaneously (regardless of their order), the train route is set to automatic route control mode.

[0109] After step S201 is completed, the train route is set to automatic route mode and must be maintained in automatic route mode. During the maintenance period, proceed to step S202 and execute the following detection process:

[0110] con14: No automatic route mode cancellation command detected;

[0111] con15: No train route detected, cancellation order.

[0112] When conditions con14 and con15 are met simultaneously (regardless of their order), the train route enters the automatic route control mode holding phase.

[0113] Step S3 includes, in sequence, S301 locking the automatic route mode; S302 detecting the train exit section; and S303 detecting the train route start signal.

[0114] When the train route is set to automatic route mode, the route will not be automatically unlocked after the train has entered and completely cleared the current route. Instead, the signal at the beginning of the train route will be automatically opened.

[0115] In a specific embodiment, steps S301, S302, and S303 are performed according to the following process:

[0116] After all steps in S2 are completed, the train enters automatic route mode and the train route is locked.

[0117] Proceed to step S301 and execute the following detection process:

[0118] con16: The automatic route-taking mode for the detected train route is effective.

[0119] The train route unlocking logic will not be activated when condition con16 is met.

[0120] After step S301 is completed, for train routes where the terminal signal and the starting signal are in opposite directions, step S302 is performed to perform the following checks:

[0121] con17: Detects that the last section inside the reverse train route terminal is being normally crossed;

[0122] con18: Detects a train that has cleared the last section inside the reverse train route terminal after it was occupied by a train.

[0123] con19: Detects that the section outside the reverse train route terminal is occupied by a train;

[0124] con20: The terminal record for detecting the reverse train route is invalid.

[0125] When conditions con3, con16, con17, con18, con19, and con20 are all met simultaneously (regardless of the order), the train clearance section record is set to be valid.

[0126] For train routes where the terminal signal and the starting signal are in the same direction, proceed to step S302 to perform the following checks:

[0127] con21: The last section of the same-direction train's route is normally crossed;

[0128] con22: Detects when the last section of the same-direction train's route is occupied by a train and then cleared;

[0129] con23: Detects that the next section of the same direction train's route is occupied by another train;

[0130] con24: The terminal record of the same direction train route is valid.

[0131] When conditions con3, con16, con21, con22, con23, and con24 are all met simultaneously (regardless of their order), the train clearance section record is set to be valid.

[0132] After step S302 is completed, during the period when the train exit section record is validly maintained, step S303 is entered to perform the following checks:

[0133] con25: Detection signal at the beginning of the train route is closed.

[0134] When conditions con3, con16, and con25 are met simultaneously (regardless of their order), the train exit section record enters the holding phase.

[0135] con26: The record of the train leaving the cleared section must remain valid;

[0136] con27: Check that the train route start signal is enabled;

[0137] con28: Checks whether the signal opening at the beginning of the train route is enabled.

[0138] When conditions con3, con6, con26, con27, and con28 are simultaneously met (regardless of their order), the train signal will automatically restart.

[0139] con29: Check that the automatic restart of the train route is effective.

[0140] When condition con29 is met, the train route start signal is automatically opened.

[0141] At this point, the train enters automatic route control mode.

[0142] When it is necessary to cancel the automatic route mode, proceed to step S4, run the automatic route exit module, and cancel the automatic route mode.

[0143] Specifically, when the station duty officer presses the automatic route button marked in red again, that is, pulls out the automatic route button, the automatic route mode of the corresponding route is disabled, the route returns to the normal train route, the route is automatically unlocked as the train moves, and the signal will no longer be automatically opened.

[0144] Step S4 includes two independent steps: S401 Automatic route mode cancellation command or S402 Train route cancellation command.

[0145] In a specific embodiment, steps S401 and S402 are performed according to the following procedures:

[0146] If step S401 is entered to exit automatic route mode, the following checks are performed:

[0147] con33: Detected that an automatic route mode cancellation command has been received.

[0148] When condition con33 is met, the automatic route mode is disabled, i.e., con16 is disabled; simultaneously:

[0149] (1) The train route signal check control logic is no longer valid, thus enabling the train route unlocking logic to operate normally;

[0150] (2) The train exit section record con26 is invalid, which in turn makes the automatic reopening of the train route con29 invalid, and the train route signal no longer automatically opens.

[0151] If step S402 is entered to exit automatic route mode, the following checks are performed:

[0152] When a station duty officer cancels a train route, this operation will also cancel the automatic route mode, and the following checks must be performed:

[0153] con34: The system has received a train route cancellation order.

[0154] When condition con34 is met, the automatic route mode is disabled, i.e., con16 is disabled; simultaneously:

[0155] (1) The train route signal check control logic is no longer valid, thus enabling the train route unlocking logic to operate normally;

[0156] (2) The train exit section record con26 is invalid, which in turn makes the automatic reopening of the train route con29 invalid, and the train route signal no longer automatically opens.

[0157] In addition, the present invention also includes an S5 automatic route signal inspection module.

[0158] Step S5 includes the following steps in sequence: S501 signal fault detection, S502 automatic train signal reopening, and S503 automatic opening of train route signal.

[0159] If a signal failure occurs, the reason for the signal being shut down must be recorded, and step S501 should be executed to perform the following checks:

[0160] con30: Detects that the train's route has not been crossed by another train.

[0161] When conditions con16, con25, and con30 are met simultaneously (regardless of their order), the automatic route fault record is valid.

[0162] After the signal fault is restored, the train signal needs to be automatically restarted and made effective. Step S502 is executed to perform the following checks:

[0163] con31: Detection of automatic route failure records is valid.

[0164] When conditions con3, con6, con26, con27, and con31 are simultaneously met (regardless of their order), the train signal will automatically restart.

[0165] After the automatic reopening of the train signal is effective, the train route signal needs to be automatically reopened. Step S503 is executed to perform the following checks:

[0166] con32: Check that the automatic restart of the train route is effective.

[0167] When condition con32 is met, the train route start signal is automatically opened.

[0168] In a specific embodiment, when a signal infrastructure failure occurs (such as a track section failure, turnout derailment, or broken signal filament), the train signal will not be automatically opened, and the train will not be able to pass the closed signal. After the fault is restored, the interlocking system can automatically restart the automatic route logic control without manual intervention, so that the signal is automatically opened, thereby enhancing the system's fault tolerance and scientific nature.

[0169] The embodiments of the present invention are as follows:

[0170] The automatic route construction process is carried out in sequence according to steps S1, S2, and S3.

[0171] S1. Establish a train route, with the route locked and the signal open:

While sections 27DG and 21DG are in the locked-in phase, conditions con1, con2, con3, con4, con5, and con6 are no longer checked, while con7 and con8 remain valid.

[0197] P301. After the 5DG and 3DG routes within the 2SI section of the train route 1X-2SI terminal are locked, the 1X signal at the beginning of the train route 1X-2SI needs to be opened. The following checks need to be performed:

[0198] con9: Detects the locking of 5DG and 3DG routes within the 2SI terminal of the 1X-2SI train route.

[0199] When conditions con3, con4, con5, con6, and con9 are simultaneously met, the train route 1X-2SI starting signal 1X is opened.

[0200] P302. After the 27DG and 21DG routes within the 2S section of the train route SS-2S terminal are locked, the SS-2S starting signal SS of the train route must be opened. The following checks must be performed:

After the train route is set to automatic route mode, the route will not automatically unlock after the train normally enters and completely clears the current route. The train route start signal will automatically open. See details. Figure 2 During the process, after the train normally enters train routes 1X-2SI and SS-2S and completely clears train routes 1X-2SI and SS-2S, train routes 1X-2SI and SS-2S are locked, the starting signal 1X of train route 1X-2SI is automatically opened, and the starting signal SS of train route SS-2S is automatically opened.

[0246] con25: Detects the 1X signal at the beginning of the train route 1X-2SI is closed.

[0247] When conditions con3, con16, and con25 are met simultaneously, the train clearance section record of train route 1X-2SI enters the holding phase.

[0248] P802: After setting the train departure section record for train route SS-2S, the departure record must be kept valid. During the retention period, the following checks must be performed:

[0251] P901: For the train to have completely cleared train route 1X-2SI, the starting signal 1X of train route 1X-2SI must be enabled for automatic restart. The following checks must be performed:

[0252] con26: The clearance section record of the 1X-2SI train route is kept valid;

[0253] con27: Enables the check of the 1X signal at the beginning of the train route 1X-2SI.

[0254] con28: Enables the check to ensure the openness of the 1X signal at the beginning of the train route 1X-2SI.

[0265] con29: Check train route SS-2S automatic restart is effective.

[0266] When condition con 29 is met, the starting signal SS of the train route SS-2S is automatically opened.

[0267] When the train route is set to automatic route mode, the route will not automatically unlock after the train has entered and completely cleared the current route. Instead, the signal at the beginning of the train route will automatically open.

[0268] To exit, proceed with the automatic route exit procedure:

[0269] If the automatic route mode cancellation command is used to cancel the automatic route mode at this time, pulling out the automatic route button will disable the automatic route mode for the corresponding route, and the route will return to normal train route. The route will automatically unlock as the train moves, and the signal will no longer automatically open. Figure 1 , Figure 2 and Figure 6 As shown, the automatic route mode of train routes 1X-2SI and SS-2S is cancelled. The automatic route mode of train routes 1X-2SI and SS-2S is invalidated and restored to the normal train route state. The train moves out of the route and clears the route. Train routes 1X-2SI and SS-2S are automatically unlocked. The train route start signal 1X and SS will no longer be automatically opened.

[0270] P1401: The station duty officer presses the automatic route button for train route 1X-2SI again, i.e., pulls out the automatic route button, which disables the automatic route mode of route 1X-2SI, restores the route to normal train route, and automatically unlocks the route as the train moves. The starting signal 1X will no longer automatically open. The following checks need to be performed:

[0271] con33: Detects received an automatic route mode cancellation command for train route 1X-2SI.

[0272] When condition con33 is met, the automatic route mode of train route 1X-2SI is disabled, i.e., con16 is disabled, and at the same time:

[0273] (1) The signal check control logic of the train route 1X-2SI starting signal 1X is no longer valid, so that the unlocking logic of the train route 1X-2SI can operate normally.

[0274] (2) The train exit section record con26 of train route 1X-2SI is invalid, which in turn makes the automatic reopening con29 of train route 1X-2SI invalid, and the starting signal 1X of train route 1X-2SI no longer automatically opens.

[0275] P1402: The station duty officer presses the automatic route button for train route SS-2S again, i.e., pulls out the automatic route button, which disables the automatic route mode of route SS-2S, restores the route to normal train route, and automatically unlocks the route as the train moves. The starting signal SS will no longer automatically open. The following checks need to be performed:

[0276] con33: Detects receipt of the automatic route mode cancellation command from train route SS-2S.

[0277] When condition con33 is met, the automatic route mode of train route SS-2S is disabled, i.e., con16 is disabled, and at the same time:

[0278] (1) The signal check control logic of the train route SS-2S starting signal SS is no longer valid, so that the unlocking logic of the train route SS-2S can operate normally.

[0279] (2) The train exit section record con26 of the train route SS-2S is invalid, which in turn makes the automatic reopening con29 of the train route SS-2S invalid, and the starting signal SS of the train route SS-2S no longer automatically opens.

[0280] If a train route cancellation command is used to cancel the train route at this time, the automatic route mode will also be canceled simultaneously; for example, Figure 1 , Figure 2 and Figure 6As shown, when the station duty officer cancels train routes 1X-2SI and SS-2S, the automatic route mode of train routes 1X-2SI and SS-2S will also be canceled, restoring the routes to normal train routes.

[0281] P1501: When the station duty officer cancels train route 1X-2SI, this operation will also cancel the automatic route mode of train route 1X-2SI. The following checks need to be performed:

[0282] con34: Detection received a cancellation command for train route 1X-2SI.

[0283] When condition con34 is met, the automatic route mode of train route 1X-2SI is disabled, i.e., con16 is disabled; simultaneously:

[0284] (1) The signal check control logic of the train route 1X-2SI starting signal 1X is no longer valid, so that the unlocking logic of the train route 1X-2SI can operate normally.

[0285] (2) The train exit section record con26 of train route 1X-2SI is invalid, which in turn makes the automatic reopening con29 of train route 1X-2SI invalid, and the starting signal 1X of train route 1X-2SI no longer automatically opens.

[0286] P1502: When the station duty officer cancels train route SS-2S, this operation will also cancel the automatic route mode of train route SS-2S. The following checks need to be performed:

[0287] con34: The system detected that a cancellation command for train route SS-2S has been received.

[0288] When condition con34 is met, the automatic route mode of train route SS-2S is disabled, i.e., con16 is disabled; simultaneously:

[0289] (1) The signal check control logic of the train route SS-2S starting signal SS is no longer valid, so that the unlocking logic of the train route SS-2S can operate normally.

[0290] (2) The train exit section record con26 of the train route SS-2S is invalid, which in turn makes the automatic reopening con29 of the train route SS-2S invalid, and the starting signal SS of the train route SS-2S no longer automatically opens.

[0291] During automatic route mode operation, the automatic route detection procedure is performed:

[0292] If the automatic route signal malfunctions, the system will enter the automatic route signal check module. Figure 1 , Figure 2 and Figure 7As shown, if a fault occurs in track section 5DG of train route 1X-2SI, a signal fault is recorded. After the fault is restored, the train route start signal 1X will be automatically opened. If a fault occurs in track section 27DG of train route SS-2S, a signal fault is recorded. After the fault is restored, the train route start signal SS will be automatically opened. The automatic route signal will be automatically opened after a fault is restored.

[0293] P1101: A signal fault has occurred in train route 1X-2SI. The signal shutdown due to the fault needs to be recorded. Perform the following checks:
