Description

Technical Field

[0001] This invention relates to the field of rail transit technology, specifically to a method for optimizing the logic of a guide signal relay. Background Technology

[0002] In the event of equipment failure on site, station staff will use a guided train reception method. Currently, there are two commonly used guided train reception methods: First, guided route locking, which is mainly used in the following two situations: (1) When the entrance signal or the receiving route signal fails and cannot be opened normally (but can light up red lights); (2) When the track circuit of the receiving route fails or when receiving a train on a receiving line occupied by a train (the turnouts on the route have fixed and reverse positions). When the turnouts are in the specified positions, the station staff press the guided button on the signal, and the corresponding signal opens the guided signal, which is displayed in red and white. After the station work is completed, the route can be unlocked by performing the general personnel release operation. Second, guided total locking, which is mainly used in the following three situations: (1) When the turnouts on the receiving route lose their fixed and reverse positions; (2) When receiving a train on a non-arrival / departure line; (3) When receiving a train in the opposite direction on a one-way receiving line. When station staff press the master lock button, the turnout in the corresponding throat area is locked. Then, pressing the signal master button opens the corresponding signal, which is displayed in red and white. After the station work is completed, pressing the master lock button again closes the signal and unlocks the turnout.

[0003] Currently, the computer interlocking system references the 6502 relay interlocking standard for handling the logic of the guide signal relay. In both guide route locking and overall guide locking scenarios, the same guide signal relay parameters are used, and both can be active simultaneously. This leads to the following problems when both guide route locking and overall guide locking are performed concurrently: 1. If a general cancellation operation is performed on the guide route, the guide signal cannot be closed, and the guide route cannot be unlocked. After canceling the overall guide locking again, the guide signal closes, and the route can be unlocked via a general manual release operation. 2. If a general manual release operation is performed on the guide route, the guide signal cannot be closed, and the guide route cannot be unlocked. After canceling the overall guide locking again, the guide signal closes, and the route can only be unlocked via a fault release operation. The design in the existing technology is unreasonable and contradicts the operator's actual intention to close the guide signal when performing a general manual release or general cancellation operation. On busy main lines, this will affect on-site operational efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a logic optimization method for a guide signal relay. It aims to solve the problem in the prior art where, after the guide signal is opened, the guide signal cannot be closed after the guide route is locked, or after the guide signal is cancelled or unlocked.

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

[0006] This invention provides a method for optimizing the logic of a guide signal relay, which is used in an interlocking system. The method includes:

[0007] The interlocking software in the interlocking system determines whether the conditions for establishing the guiding route are met based on the actual station conditions, and outputs the locking conditions for the guiding route.

[0008] The interlocking software receives the guide path locking condition, and based on the received external guide command, the guide path locking condition, and the scenario of opening the guide signal, analyzes the guide signal opening logic and outputs the conditions that need to be checked to open the guide signal.

[0009] The interlocking software determines the configuration of the guidance signal opening conditions based on the analysis of the guidance signal opening logic, and outputs the guidance signal.

[0010] Preferably, a hostile route is defined as a route that cannot be opened simultaneously with a guiding route;

[0011] The hostile condition is defined as: a hostile route that has already established a guiding route;

[0012] The lookup condition is defined as follows: no other routes have been established with the pilot route terminal as the terminal.

[0013] The determination of whether the conditions for establishing the guiding path are met specifically includes:

[0014] Condition 1: The turnouts and protective turnouts of the guiding route are at the designated positions of the guiding route;

[0015] Condition 2: The turnouts and protective turnouts of the guiding route are not blocked;

[0016] Condition 3: The hostile condition of the guided route is not met;

[0017] Condition 4: The inspection conditions for the guiding route are met.

[0018] The conditions 1 to 4 are evaluated sequentially. If all of the conditions 1, 2, 3 and 4 are true, the path locking condition is satisfied, and the result of satisfying the path locking condition is output. If any of the conditions 1 to 4 are not true, the path locking condition is not satisfied.

[0019] Preferably, the step of analyzing the guidance signal opening logic based on the received external guidance command, the guidance path locking condition, and the scenario of opening the guidance signal specifically includes: entering the corresponding guidance path signal processing or guidance path locking signal processing based on whether the track throat area is in a guidance overall locking state.

[0020] If the track throat area is not in the overall guidance lockout state, then proceed to the guidance route signal processing;

[0021] If the track throat area is in the guided total lockout state, then the guided total lockout signal processing will begin.

[0022] Preferably, the step of analyzing the guidance signal opening logic based on the received external guidance command, the guidance path locking condition, and the scenario of opening the guidance signal is implemented by setting up two independent modules. The two independent modules include:

[0023] If the track throat area is not in the overall guide lockout state, the guide route signal processing module will enter the guide route signal processing stage, that is, the guide route signal processing module will be used for processing.

[0024] If the track throat area is in a guided total locking state, the guided total locking signal processing module will enter the guided total locking signal processing stage, that is, the guided total locking signal processing module will be used for processing.

[0025] Preferably, if the track throat area is not in the guided overall locked state, then the guided path signal processing begins. The processing method of the guided path signal processing module specifically includes:

[0026] The overall guide lock state is defined as the state of the throat after the operator presses the overall guide lock button.

[0027] The train route signal is defined as: the signal of the train route that has the same starting and ending points as the guiding route.

[0028] The delayed unlocking process is defined as follows: after the guide signal is opened, the overall unlocking operation is performed, and the guide route is unlocked with a delay.

[0029] The first section inside the signal is defined as: the first section in the route guiding the path starting from the position of the initial signal.

[0030] The guidance route signal processing is performed according to the following different conditions:

[0031] Condition 5: Determine whether the guiding route locking condition is met;

[0032] Condition 6: Determine whether the train route signal is not open;

[0033] Condition 7: Determine whether the system is not in the delayed unlocking process;

[0034] Condition 8: Determine whether the hostile conditions for the guiding route are not met;

[0035] Condition 9: Determine whether a total cancellation or total removal of personnel operation has not been performed;

[0036] Condition 10: Determine if the filament of the starting signal is intact;

[0037] Condition 11: Determine whether the turnout / protective turnout on the guiding route is in the designated position on the guiding route;

[0038] Condition 12: Determine whether the first section inside the signal is clear.

[0039] The conditions 5 to 12 are judged sequentially. If all conditions 5 to 11 are satisfied and the result of judging condition 12 is idle, then the condition for opening the guide route signal is satisfied.

[0040] If all conditions 5 to 11 are met and the judgment result of condition 12 is not idle, then the guiding route signal meets the condition of automatically closing after being open for 15 seconds.

[0041] Preferably, if all conditions 5 to 11 are satisfied and the result of condition 12 is idle, then the guide route signal opening condition is satisfied, and conditions 9 to 12 are continuously evaluated during the guide route signal opening period.

[0042] If any one of the conditions 9 to 12 is not met, then the guiding path opening condition is not met.

[0043] Preferably, if all conditions 5 to 11 are satisfied and the result of condition 12 is idle, then the guide route signal opening condition is satisfied, and the following condition 13 is judged during the guide route signal opening period:

[0044] Condition 13: Determine if there is a situation where a train crosses the starting signal.

[0045] If condition 13 is met, i.e. there is a situation where a train crosses the starting signal, then the condition for opening the guiding route signal is not met.

[0046] If condition 13 is not met, i.e. there is no train crossing the starting signal, then the condition for opening the guiding route signal is met.

[0047] Preferably, if all conditions 5 to 11 are met and the judgment result of condition 12 is not idle, then the guiding route signal meets the condition of automatically closing after a predetermined opening time, and the guiding route starts a countdown to open.

[0048] Preferably, during the countdown opening period, conditions 10 and 11 are continuously evaluated. If either condition 10 or condition 11 is not met, the opening condition for the guide route signal is not met, and the opening of the guide route signal is closed.

[0049] Preferably, the approach section is defined as: the section outside the starting signal of the guiding route;

[0050] The following conditions are also set:

[0051] Condition 14: Whether to re-apply for guidance;

[0052] Condition 15: Has the train completely cleared the approach section and entered the guided route?

[0053] If condition 14 is met during the countdown opening period, i.e., the guidance is reprocessed, the scheduled time is reset and the countdown is restarted. After the countdown ends, the conditions for opening the guidance route are no longer met.

[0054] During the countdown opening period, if condition 15 is met, that is, the train clearing approach section has completely entered the inside of the guide route, then the guide route signal opening condition is immediately not met.

[0055] During the countdown opening period, if condition 15 is not met, that is, the train has not cleared the approach section and fully entered the guide route, then the satisfaction of condition 14 is determined, and based on the satisfaction of condition 14, it is determined whether the guide route signal opening condition is met.

[0056] Preferably, if the track throat area is in a guided overall locking state, then the guided overall locking signal processing is initiated. The processing method of the guided overall locking signal processing module specifically includes:

[0057] Set the following conditions:

[0058] Condition 16: The guiding route signal is not open;

[0059] Condition 17: Train route signal not open;

[0060] Condition 18: Not in the process of delayed unlocking;

[0061] Condition 19: The filament of the starting signal is intact;

[0062] Condition 20: The general personnel release operation has not been completed;

[0063] Condition 21: The first section inside the signal is clear;

[0064] If all of conditions 16 to 21 are satisfied, then the condition for opening the overall locking signal is satisfied; if any one of conditions 16 to 21 is not satisfied, then the condition for opening the overall locking signal is not satisfied.

[0065] Preferably, the following conditions are also set:

[0066] Condition 22: The master lock has been released.

[0067] If all of conditions 16 to 21 are satisfied, then the condition for opening the overall locking signal is satisfied. During the process of opening the overall locking signal, the satisfaction of conditions 19 to 22 is continuously judged. If any of conditions 19 to 22 is not satisfied, then the condition for opening the overall locking signal is not satisfied.

[0068] Preferably, the interlocking software determines the configuration of the guide signal opening conditions based on the analysis of the guide signal opening logic, and outputs the guide signal, specifically including the following steps:

[0069] Step S1: Determine whether the locking conditions of the guiding route are met;

[0070] Step S2: Determine whether the conditions for opening the guiding route signal are met;

[0071] Step S3: Determine whether the conditions for opening the main locking signal are met;

[0072] Step S4: Determine whether the boot signal output logic is correct;

[0073] Step S5: Generate the boot signal output logic;

[0074] Based on the judgment results of steps S2 and S3, step S4 is judged, and based on the judgment result of step S4, step S5 is executed.

[0075] Preferably, step S1 includes two judgment results: judgment result S11: the guiding route locking condition has been met; judgment result S12: the guiding route locking condition has not been met.

[0076] Step S2 includes two judgment results: Judgment result S21: The condition for opening the guide route signal has been met; Judgment result S22: The condition for opening the guide route signal has not been met.

[0077] Step S3 includes two judgment results: Judgment result S31: The opening condition of the guide total locking signal has been met; Judgment result S32: The opening condition of the guide total locking signal has not been met.

[0078] Step S4 includes two judgment results:

[0079] The judgment result S41: If the judgment result of step S2 is the judgment result S21 or the judgment result of step S3 is the judgment result S31, then the guiding signal output logic is configured.

[0080] The judgment result S42: If the judgment result of step S2 is the judgment result S22 and the judgment result of step S3 is the judgment result S32, then the guiding signal output logic is not constituted.

[0081] Preferably, step S5 includes:

[0082] Step S51: If the judgment result of step S4 is the judgment result S41, then generate the logic that the guiding signal output is valid;

[0083] Step S52: If the judgment result of step S4 is the judgment result S42, then generate the logic that the guiding signal output is not valid.

[0084] Compared with the prior art, the present invention has the following beneficial effects:

[0085] 1. This invention proposes a logic optimization method for a guide signal relay, defines a guide route signal processing module, and makes a judgment on the logic of opening the guide route signal when the guide route is locked, which can ensure that the guide signal for opening the guide route is not closed after the procedure of releasing the overall guide lock is completed;

[0086] 2. This invention defines a master lockout signal processing module and makes a judgment on the logic of opening the master lockout signal under the master lockout condition. This can ensure that the master lockout opening signal can be closed in time after the master lockout or master lockout procedures are completed.

[0087] 3. This invention incorporates two modules into the opening and closing logic of the guidance signal. Since the two modules are independent of each other, it can ensure that only one of the guidance route signal and the guidance total lock signal is valid and does not affect each other. This solves the problem that after the guidance route lock is processed, the guidance signal is opened and then the guidance total lock is processed, and after the total cancellation or total release procedure is processed, the guidance signal cannot be closed. This improves work efficiency while taking safety into account. Attached Figure Description

[0093] The following is in conjunction with the appendix Figure 1-4 The following detailed description of the proposed guide signal relay logic optimization method further illustrates the present invention. The advantages and features of the present invention will become clearer from the following description. It should be noted that the accompanying 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 accompanying 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 illustrative purposes to aid those skilled in the art 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.

[0094] Given the problem in the existing technology that after the guidance route is locked, the guidance signal cannot be closed after the guidance signal is opened, or after the guidance is locked, cancelled, or released, the guidance signal cannot be closed.

[0095] refer to Figure 1 As shown, this embodiment provides a method for optimizing the logic of a guide signal relay, which is used in an interlocking system. The method includes the following three stages:

[0096] Phase 1: Guided route locking judgment phase. The interlocking software in the interlocking system judges whether the conditions for establishing the guided route are met based on the actual station conditions and outputs the conditions for locking the guided route.

[0097] A hostile route is defined as a route that cannot be opened simultaneously with a guiding route; a hostile condition is defined as a hostile route for which a guiding route has already been established; a lookup condition is defined as no other route has been established with the guiding route terminal as its endpoint. The determination of whether the guiding route establishment condition is met specifically includes:

[0098] Condition 1: The turnouts and protective turnouts of the guiding route are at the designated positions of the guiding route;

[0099] Condition 2: The turnouts and protective turnouts of the guiding route are not blocked;

[0100] Condition 3: The hostile condition of the guided route is not met;

[0101] Condition 4: The conditions for checking the guiding route are met.

[0102] The conditions 1 to 4 are evaluated sequentially. If all of the conditions 1, 2, 3 and 4 are true, the path locking condition is satisfied, and the result of satisfying the path locking condition is output. If any of the conditions 1 to 4 are not true, the path locking condition is not satisfied.

[0103] The second stage is the guidance signal opening logic judgment stage. The interlocking software receives the guidance path locking condition and analyzes the guidance signal opening logic based on the received external guidance command, the guidance path locking condition, and the scenario of opening the guidance signal, and outputs the conditions that need to be checked for opening the guidance signal.

[0104] The aforementioned analysis of the guidance signal opening logic based on the received external guidance command, the guidance path locking condition, and the scenario of opening the guidance signal specifically includes: entering the corresponding guidance path signal processing or guidance path locking signal processing based on whether the track throat area is in the overall guidance locking state.

[0105] If the track throat area is not in the overall guidance lockout state, then the guidance route signal processing begins; if the track throat area is in the overall guidance lockout state, then the overall guidance lockout signal processing begins.

[0106] The aforementioned analysis of the guidance signal opening logic based on the received external guidance command, the guidance path locking condition, and the scenario of opening the guidance signal is implemented by setting up two independent modules. These two independent modules include:

[0107] If the track throat area is not in the overall guidance lockout state, the guidance route signal processing module will enter the guidance route signal processing stage, i.e., the guidance route signal processing module will be used for processing. If the track throat area is in the overall guidance lockout state, the guidance lockout signal processing module will enter the guidance lockout signal processing stage, i.e., the guidance lockout signal processing module will be used for processing.

[0108] refer to Figure 2 As shown, if the track throat area is not in the guided overall locking state, then the guided route signal processing begins. The processing method of the guided route signal processing module specifically includes:

[0109] Define the overall locking status of the guide as: the state of the throat after the operator presses the overall locking button of the guide; define the train route signal as: the signal of the train route at the same starting and ending points as the guide route; define the delayed unlocking process as: after the guide signal is opened, the overall unlocking operation is performed, and the guide route is unlocked after a delay; define the first section inside the signal as: the first section in the guide route starting from the position of the starting signal.

[0110] The guidance route signal processing is performed according to the following different conditions:

[0111] Condition 5: Determine whether the guiding route locking condition is met;

[0112] Condition 6: Determine whether the train route signal is not open;

[0113] Condition 7: Determine whether the system is not in the delayed unlocking process;

[0114] Condition 8: Determine whether the hostile conditions for the guiding route are not met;

[0115] Condition 9: Determine whether a total cancellation or total removal of personnel operation has not been performed;

[0116] Condition 10: Determine if the filament of the starting signal is intact;

[0117] Condition 11: Determine whether the turnout / protective turnout on the guiding route is in the designated position on the guiding route;

[0118] Condition 12: Determine whether the first section inside the signal is clear.

[0119] The conditions 5 to 12 are judged sequentially. If all conditions 5 to 11 are satisfied and the result of judging condition 12 is idle, then the condition for opening the guide route signal is satisfied.

[0120] If all conditions 5 to 11 are met and the result of condition 12 is "not idle," then the guiding route signal satisfies the condition of automatically closing after 15 seconds of being open. If all conditions 5 to 11 are met and the result of condition 12 is "idle," then the guiding route signal opening condition is met. During the opening period of the guiding route signal, conditions 9 to 12 are continuously evaluated. If any one of conditions 9 to 12 is not met, then the guiding route opening condition is not met. If all conditions 5 to 11 are met and the result of condition 12 is "idle," then the guiding route signal opening condition is met. During the opening period of the guiding route signal, the following condition 13 is evaluated:

[0121] Condition 13: Determine if there is a situation where a train crosses the starting signal.

[0122] If condition 13 is met, i.e., a train crosses the starting signal, the condition for opening the guiding route signal is not met; if condition 13 is not met, i.e., no train crosses the starting signal, the condition for opening the guiding route signal is met. If conditions 5 to 11 are all met and the result of condition 12 is "not idle," the guiding route signal meets the condition of automatically closing after a predetermined opening time, and the guiding route begins a countdown to open. During the countdown, conditions 10 and 11 are continuously evaluated. If either condition 10 or 11 is not met, the condition for opening the guiding route signal is not met, and the opening of the guiding route signal is closed.

[0123] The approach section is defined as the section outside the starting signal of the guiding route.

[0124] Set the following conditions:

[0125] Condition 14: Whether to re-apply for guidance;

[0126] Condition 15: Has the train cleared the approach section and fully entered the guided route?

[0127] During the countdown period, if condition 14 is met (i.e., guidance is re-processed), the predetermined time is reset and the countdown restarts. After the countdown ends, the guidance route opening condition is no longer met. During the countdown period, if condition 15 is met (i.e., the train has cleared the approach section and completely entered the guidance route), the guidance route signal opening condition is immediately not met. During the countdown period, if condition 15 is not met (i.e., the train has not cleared the approach section and completely entered the guidance route), the satisfaction of condition 14 is assessed, and based on the satisfaction of condition 14, it is determined whether the guidance route signal opening condition is met.

[0128] If the track throat area is in a guided overall lockout state, then the guided overall lockout signal processing begins. The processing method of the guided overall lockout signal processing module specifically includes:

[0129] Set the following conditions:

[0130] Condition 16: The guiding route signal is not open.

[0131] Condition 17: Train route signal not open.

[0132] Condition 18: Not in the process of delayed unlocking.

[0133] Condition 19: The filament of the starting signal is intact.

[0134] Condition 20: The total number of people has not been released.

[0135] Condition 21: The first section inside the signal is clear.

[0136] If all of conditions 16 to 21 are satisfied, then the condition for opening the overall locking signal is satisfied; if any one of conditions 16 to 21 is not satisfied, then the condition for opening the overall locking signal is not satisfied.

[0137] The following conditions are also set:

[0138] Condition 22: The main lock has been released.

[0139] If all of conditions 16 to 21 are satisfied, then the condition for opening the overall locking signal is satisfied. During the process of opening the overall locking signal, the satisfaction of conditions 19 to 22 is continuously judged. If any of conditions 19 to 22 is not satisfied, then the condition for opening the overall locking signal is not satisfied.

[0140] The third stage: the guidance signal output logic stage, in which the interlocking software determines the composition of the guidance signal opening conditions based on the analysis of the guidance signal opening logic, and outputs the guidance signal.

[0141] refer to Figure 3 As shown, the interlocking software determines the configuration of the guide signal opening condition based on the analysis of the guide signal opening logic, and outputs the guide signal. Specifically, this includes the following steps:

[0142] Step S1: Determine whether the guiding route locking condition is met.

[0143] Step S2: Determine whether the conditions for opening the guiding route signal are met.

[0144] Step S3: Determine whether the conditions for opening the main locking signal are met.

[0145] Step S4: Determine whether the boot signal output logic is configured correctly.

[0146] Step S5: Generate the boot signal output logic.

[0147] Based on the judgment results of steps S2 and S3, step S4 is judged, and based on the judgment result of step S4, step S5 is executed.

[0148] Step S1 includes two judgment results: Judgment result S11: The guiding path locking condition has been met; Judgment result S12: The guiding path locking condition has not been met. Step S2 includes two judgment results: Judgment result S21: The guiding path signal opening condition has been met; Judgment result S22: The guiding path signal opening condition has not been met. Step S3 includes two judgment results: Judgment result S31: The guiding total locking signal opening condition has been met; Judgment result S32: The guiding total locking signal opening condition has not been met. Step S4 includes two judgment results: Judgment result S41: If the judgment result of step S2 is judgment result S21 or the judgment result of step S3 is judgment result S31, then the guiding signal output logic is configured; Judgment result S42: If the judgment result of step S2 is judgment result S22 and the judgment result of step S3 is judgment result S32, then the guiding signal output logic is not configured. Step S5 includes: Step S51: If the judgment result of step S4 is the judgment result S41, then generate the logic for the guidance signal output to be true; Step S52: If the judgment result of step S4 is the judgment result S42, then generate the logic for the guidance signal output to be false.

[0149] Figure 4 This is a sample station layout diagram. Figure 4 The example site diagram illustrates the above-mentioned optimization method for the guide signal relay logic.

[0150] Signals X and XF have guide buttons and contain a total of 4 guide routes: X-SI, X-SII, XF-SI, and XF-SII. All switches are not blocked, there are no other hostile conditions on the station map, no routes have been processed, and all inspection conditions are met.

[0151] The interlocking software is based on the first stage of the above embodiment: the path locking judgment stage.

[0152] Condition 1: Only the turnouts and protective turnouts of the X-SII route are in the designated positions; the other three routes do not meet this condition.

[0153] Condition 2: All turnouts and protective turnouts are not blocked;

[0154] Condition 3: There are no other hostile conditions, no routes have been initiated, and the hostile conditions for all routes are not met;

[0155] Condition 4: All the conditions for checking the guiding routes are met.

[0156] Based on the actual station map, it can be seen that only X-SII has the conditions for locking the guide route, and the result of X-SII guide route locking condition being met can be output. The other three routes do not meet the conditions.

[0157] The second and third stages of the above embodiments are described below in conjunction with different operating scenarios.

[0158] Scenario 1: The throat is not in the guided lock state, then press the guide buttons X and XF of the signal machine.

[0159] According to the second stage of the above embodiment: the guiding path signal processing module in the guiding signal open logic judgment stage, it can be known that:

[0160] Condition 5: According to the output of the guide path locking phase, only X-SII meets the guide path locking condition, while the other three paths do not.

[0161] Condition 6: All train route signals are not open;

[0162] Condition 7: None of the routes are in the delayed unlocking process;

[0163] Condition 8: The hostility conditions for all routes are not met;

[0164] Condition 9: No overall cancellation or overall deregistration operation has been completed;

[0165] Condition 10: The filaments of both the X and XF starting signals are intact;

[0166] Condition 11: Only the turnouts and protective turnouts of the X-SII route are in the designated positions; the other three routes do not meet this condition.

[0167] Condition 12: All segments are idle.

[0168] At this point, only the X-SII route meets the condition for opening the pilot route signal; the other three routes do not.

[0169] According to the third stage of the above embodiment: the guide signal output logic stage, it can be seen that:

[0170] Step S1: The locking condition for the X-SII guided route is met, but the conditions for the other routes are not met;

[0171] Step S2: The X-SII guide route signal opening condition is met, while the other routes are not.

[0172] Step S3: Since the throat is not in the guided total lock state, are the conditions for opening the guided total lock signal of all routes met?

[0173] Step S4: The X-SII guide path signal output logic is constructed, while the guide signal output logic for the other paths is not constructed;

[0174] Step S5: Generate the guide signal output logic for the X-SII path.

[0175] In summary, based on Figure 3 The output logic only outputs a guidance signal when the X-SII guidance route signal opening condition is met. Since the release of the overall guidance lockout is not processed in the second stage's guidance route signal opening judgment condition, the guidance signal that has been opened will not be closed after the release of the overall guidance lockout procedure is completed.

[0176] Scenario 2: With the throat in the guided lockout state, press the guide buttons X and XF on the signal device.

[0177] According to the second stage of the above embodiment: the guide signal opening logic judgment stage, the guide total latching signal processing module can be known that:

[0178] Condition 16: All guiding route signals are not open;

[0179] Condition 17: All train route signals are not open;

[0180] Condition 18: None of the routes are in the delayed unlocking process;

[0181] Condition 19: The filaments of both the X and XF starting signals are intact;

[0182] Condition 20: The general personnel release operation has not been completed;

[0183] Condition 21: All segments are idle;

[0184] Condition 22: The main lock has not been released.

[0185] At this point, both X and XF meet the conditions for opening the overall locking signal.

[0186] According to the third stage of the above embodiment: the guide signal output logic stage, it can be seen that:

[0187] Step S1: The locking condition for the X-SII guided route is met, but the conditions for the other routes are not met;

[0188] Step S2: The conditions for opening all guiding path signals are not met;

[0189] Step S3: The conditions for opening the X and XF guide total locking signals are met;

[0190] Step S4: X and XF guide the overall latching signal output logic;

[0191] Step S5: Generate the boot signal output logic for X and XF.

[0192] In summary, based on Figure 3The output logic ensures that the opening conditions for the master lockout signals X and XF are met, and a master lockout signal is output. Because the master lockout signal processing module in the second stage requires continuous checking of the conditions in steps S4 to S7 during the opening process, if any condition is not met, the master lockout signal opening condition is not met. Therefore, the master lockout opening signal can be promptly closed after the master lockout or master lockout procedures are completed.

[0193] Scenario 3: If the throat is not in the guided master lock state, press the guide buttons X and XF on the signal controllers. Based on the conclusion of Scenario 1, only the guide path X-SII guide path signal opening condition is met, and a guide signal is output. At this time, perform the guided master lock to put the throat in the guided master lock state, and then press the buttons X and XF on the signal controllers.

[0194] According to the second stage of the above embodiment: the guide signal opening logic judgment stage, the guide total latching signal processing module can be known that:

[0195] Condition 16: The X-SII pilot route signal is open, while the other routes are not open;

[0196] Condition 17: All train route signals are not open;

[0197] Condition 18: None of the routes are in the delayed unlocking process;

[0198] Condition 19: The filaments of both the X and XF starting signals are intact;

[0199] Condition 20: The general personnel release operation has not been completed;

[0200] Condition 21: All segments are idle;

[0201] Condition 22: The main lock has not been released.

[0202] Since X-SII has the condition to open the guide path signal, only XF has the condition to open the guide total blocking signal.

[0203] According to the third stage of the above embodiment: the guide signal output logic stage, it can be seen that:

[0204] Step S1: The locking condition for the X-SII guided route is met, but the conditions for the other routes are not met;

[0205] Step S2: The X-SII guide route signal opening condition is met, while the other routes are not.

[0206] Step S3: The XF-guided total locking signal opening condition is met;

[0207] Step S4: The output logic of the X-SII guiding path signal and the XF guiding total latching signal is configured;

[0208] Step S5: Generate the boot signal output logic for X and XF.

[0209] according to Figure 3 The output logic ensures that the opening conditions for the X-SII guide route signal and the XF guide total lockout signal are met, and then outputs a guide signal. Since step S1 in the guide total lockout signal processing module in the second stage checks whether the guide route signal is not open, and step S5 in the guide route signal processing module checks whether a total cancellation or total release operation has not been performed, it ensures that only one of the guide route signal and the guide total lockout signal is valid and does not affect each other. After the guide signal is opened, the guide total lockout can be performed; performing a total cancellation or total release operation can close the guide signal.

[0210] In summary, this embodiment proposes a method for optimizing the logic of the guidance signal relay. It analyzes the conditions that need to be checked when opening the guidance signal based on different scenarios. A guidance route signal processing module and a guidance master lockout signal processing module are proposed, integrating these two independent modules into the opening and closing logic of the guidance signal. This solves the problem that after opening the guidance signal by performing guidance route lockout, the guidance master lockout cannot be performed, and the guidance signal cannot be closed after performing master cancellation or master release procedures. This improves operational efficiency while ensuring safety.
