Description

Technical Field

[0001] The present invention relates to the technical field of train control, and in particular to a method for controlling signal reopening of a signal machine, a computer interlocking system and a computer-readable storage medium. Background Art

[0002] When a train is processing an approach, due to the presence of a fault-locked section within the route, the signal at the beginning of the route is in the signal-off state, indicating that trains outside the route cannot enter the route, that is, the approach processing is unsuccessful.

[0003] In the existing method of controlling the signal restart, it is checked whether there is a train entering the section within the route. If it is detected that there is no train entering, the signal can be controlled to restart the signal. However, this method has the problem that there is actually a train entering the section within the route, but the occupancy of the first and second sections of the route is not collected, resulting in misjudgment that there is no train entering the route, so there is a risk of the next train rear-ending the current train in the route after the signal is restarted. Summary of the invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one object of the present invention is to provide a method for controlling the signal reopening of a signal machine, which does not check whether a train enters an approach route, avoids misjudgment of train entry, and improves the safety of train scheduling and driving.

[0005] The method for controlling the signal reopening of a signal machine according to the first embodiment of the present invention comprises the following steps:

[0006] receiving a signal restart instruction of a target signal machine, and determining that the target signal machine is in a closed state and the target signal machine is a starting signal machine of a target route;

[0007] If it is determined that the target signal is not blocked and the turnout and section of the target route where the target signal is located are not blocked, then a route opening condition check is performed;

[0008] Determining that the route opening condition is not satisfied, and the direction of the fault-locked section is consistent with the direction of the target route, triggering the opening delay timing, wherein the route opening condition is not satisfied including the presence of the fault-locked section in the target route; and

[0009] During the timing of the opening delay, if any route opening condition other than the fault-locked section is not satisfied, the opening delay timing is stopped and the target signal is controlled to maintain a closed state;

[0010] Alternatively, when the opening delay timer reaches a preset time length, and there is only the faulty locked section in the target route that does not meet the signal opening condition, the faulty locked section of the target route is set to normal locking, and the target signal machine is controlled to reopen the signal.

[0011] Therefore, according to the method for controlling the reopening of signal lights in an embodiment of the present invention, during the timing period of the triggered open delay, when it is determined that the opening conditions of any route except the faulty locked section are not met, the open delay timing is stopped and the target signal light is controlled to maintain a closed state; and when the open delay timing reaches a preset time, if there is and only the faulty locked section in the target route that does not meet the signal opening conditions, the faulty locked section of the target route is set to a normal lock and the target signal light is controlled to reopen the signal. This can accurately determine whether there is a train running in the route without checking the entry of the train. When the route is complete, the target signal light is delayed by a preset time to reopen the signal, thereby avoiding the misjudgment of the entry of the train due to the failure to collect the occupancy of the first section and the second section of the route, thereby avoiding the safety risk caused by the misjudgment and improving the safety of route handling and train scheduling.

[0012] According to some embodiments of the present invention, the method for controlling the reopening of a signal light further comprises: obtaining axle counter detection data of the route where the target signal light is located during the timing of the opening delay,

[0013] The target route has and only has the fault-locked section in the target route that does not meet the signal release condition, including: the axle counter detection data does not change, then it is determined that the fault-locked section of the target route where the target signal is located is not occupied by a train;

[0014] The condition for opening any route other than the fault-locked section is not satisfied, including: if the axle counter detection data changes, it is determined that the fault-locked section of the target route where the target signal is located is occupied by a train.

[0015] According to some embodiments of the present invention, the preset duration is obtained based on the time from the axle counter detection section being cleared to being occupied, the engine electronic controller (Engine Electronic Control, EEC) operating cycle, the timeout time of the EEC and the element control computer (Element control computer, ECC), the ECC operating cycle, and the timeout time of the ECC and the computer interlocking system.

[0016] According to some embodiments of the present invention, the preset duration ranges from 4.5s to 5.5s.

[0017] According to some embodiments of the present invention, determining that the target signal is a route start signal includes:

[0018] Traverse all the internal routes of the computer interlocking system;

[0019] Comparing the identity information of the signal lights on all routes with the identity information of the target signal light;

[0020] If the identity identification information of the starting signal of any one of all the routes is consistent with the identity identification information of the target signal, the target signal is determined to be the starting signal of the route.

[0021] According to some embodiments of the present invention, the method for controlling the signal restart of a traffic light further includes:

[0022] If it is determined that the direction of the fault-locked section is inconsistent with the approach direction, the target signal is controlled to maintain a closed state.

[0023] According to some embodiments of the present invention, after receiving a signal restart instruction of a target signal machine, the method further includes:

[0024] If it is determined that the target signal is in an open state, the target signal is controlled to maintain the open state.

[0025] According to some embodiments of the present invention, after controlling the target signal machine to restart the signal, the method further includes:

[0026] Periodically performing the route opening condition check;

[0027] If it is determined that the route where the target signal is located does not meet the route opening condition, the target signal is controlled to be closed.

[0028] The computer interlocking system according to the second embodiment of the present invention comprises:

[0029] at least one processor;

[0030] a memory communicatively coupled to at least one of the processors;

[0031] Wherein, the memory stores a computer program that can be executed by at least one of the processors, and when at least one of the processors executes the computer program, the method for controlling the reopening of a signal of a traffic light according to the embodiment of the first aspect of the present invention is implemented.

[0032] According to the computer-readable storage medium of the third aspect embodiment of the present invention, a computer program is stored thereon, and it is characterized in that when the computer program is executed by a processor, the method for controlling the reopening of a signal of a traffic light according to the above-mentioned first aspect embodiment of the present invention is implemented.

[0033] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to be able to understand the features and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present invention. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0039] In the prior art, when handling an approach, if it is found that the signal at the beginning of the approach is closed, that is, the approach is locked, check whether there is a train entering the approach. If no train is detected entering the approach, control the signal at the beginning of the approach to reopen the signal. In this method, if the status of the approach section outside the approach and the first section of the approach changes from [occupied, cleared] to [cleared, occupied], from [occupied, cleared] to [occupied, occupied], or from [occupied, occupied] to [cleared, occupied], it is considered that a train is entering the approach. Figure 1 Taking the route S2_S3 shown as an example, the method includes the following scenarios:

[0040] ① If the approach section PT5 is occupied and the second section PT2 in the approach route changes from occupied to cleared, the manual restart of the end signal S2 is successful;

[0041] ② If the approach section PT5 is occupied and the third section PT3 in the approach route changes from occupied to cleared, the manual restart of the end signal S2 is successful;

[0042] ③ It is collected that the approach section PT5 is occupied, the first section PT1 in the approach route changes from occupied to cleared, and the manual restart end signal S2 fails; and

[0043] ④ It was collected that the approach section PT5 was occupied, the third section PT3 changed from occupied to cleared, and the manual restart of the end signal S2 was successful.

[0044] For the above scenario ④, there is a possibility that the train enters the route S2_S3, but the occupancy of both the first section PT1 and the second section PT2 is not collected. If the first section PT1 and the second section PT2 are in an occupied state, but the occupancy state is not collected, after the S2 signal of the starting end signal is successfully reopened, the next train may rear-end the current train in the route, so there is a safety risk.

[0045] To solve the above problems, refer to Figure 2 A first aspect of the present invention provides a method for controlling the reopening of a traffic light signal.

[0046] Specifically, Figure 2 As shown, the method for controlling the reopening of a signal machine according to an embodiment of the present invention comprises the following steps:

[0047] S1, receiving the signal restart instruction of the target signal, confirming that the target signal is in the closed state and the target signal is the starting signal of the target route.

[0048] The target signal refers to the signal to which the signal restart command is directed. In other words, the signal restart instruction of the target signal is to command the target signal to restart the signal so that it is in a signal open state. The signal open state may refer to the signal being in a green light or yellow light state. For example, the computer interlocking (CI) receives a signal restart instruction from the target signal of the automatic train supervision system (ATS) to instruct the target signal to reopen the signal.

[0049] The target signal is in the closed state, which means that the train is not allowed to pass the target signal. For example, the signal is in the closed state, which means that the signal is in the red light state. When the target signal is determined to be in the closed state and the target signal is the starting signal of the target route, it means that the train is not allowed to pass the starting signal of the target route, that is, the train is not allowed to enter the target route.

[0050] S2, determine that the target signal is not blocked and the switch and section of the target route where the target signal is located are not blocked, then perform the route opening condition check.

[0051] When it is determined that the target signal is in the closed state and is the starting signal, before performing the route opening condition check, it is also necessary to check whether the target signal is not blocked, the turnout is not blocked, and the section is not blocked. Here, the target signal is not blocked, which means that the signal state of the target signal is not locked and can be changed according to the control. The turnout is not blocked, which means that the turnout is not locked and can be turned. The section is not blocked, which means that the route is allowed to be arranged through the section. The route opening condition check is only performed when the target signal is not blocked, the turnout is not blocked, and the section is not blocked. The purpose of the route opening condition check is to determine whether the target signal can reopen the signal.

[0052] S3, if it is determined that the route opening condition is not met and the direction of the faulty locked section is consistent with the direction of the target route, then the opening delay timing is triggered, wherein the route opening condition is not met including the existence of a faulty locked section in the target route.

[0053] Among them, fault locking includes route locking caused by a train currently passing through the above-mentioned route and route locking caused by related equipment failure in the route. The direction of the fault locking section refers to whether the direction of the fault locking section is in the upward direction or the downward direction. When the direction of the target route is in the upward direction, the direction of the fault locking section is also in the upward direction, or when the direction of the target route is in the downward direction, the direction of the fault locking section is also in the downward direction, and the direction of the fault locking section is consistent with the direction of the target route. When determining the route opening conditions, including the existence of a fault locking section in the target route causing the inspection conditions to be unsatisfied, and the direction of the fault locking section is consistent with the direction of the target route, the timing of the preset duration begins.

[0054] S4: During the opening delay timing, if the opening condition of any route other than the fault-locked section is not met, the opening delay timing is stopped and the target signal is controlled to maintain the closed state; or

[0055] S5, when the opening delay time reaches the preset time, if there is only a faulty locked section in the target route that does not meet the signal opening condition, the faulty locked section in the target route is set to normal locking, and the target signal machine is controlled to reopen the signal.

[0056] Specifically, steps S4 and S5 are steps for detecting whether the target route meets the signal opening condition. If during the timing of the opening delay, there are other factors or faults besides the faulty locked section, for example, a train currently passes through the faulty locked section in the target route, so that the target route does not meet the route opening condition, it means that the target route cannot be processed at present, and the signal at the beginning of the target route cannot be reopened, so the delay timing is stopped at this time and the target signal is controlled to maintain the closed state. On the contrary, if until the opening delay timing reaches the preset time length, the target route has and only the faulty locked section in the target route does not meet the signal opening condition, it means that the target route is allowed to be processed, so the faulty locked section of the target route is set to ordinary locking, and the target signal is controlled to reopen the signal, indicating that the next train can enter the target route.

[0057] Therefore, according to the method for controlling the reopening of signal lights in an embodiment of the present invention, during the timing period of the triggered open delay, when it is determined that the opening conditions of any route except the faulty locked section are not met, the open delay timing is stopped and the target signal light is controlled to maintain a closed state; and when the open delay timing reaches a preset time, if there is and only the faulty locked section in the target route that does not meet the signal opening conditions, the faulty locked section of the target route is set to a normal lock and the target signal light is controlled to reopen the signal. This can accurately determine whether there is a train running in the target route, especially in the faulty locked section, without checking the entry of the train, thereby avoiding the misjudgment of the entry of the train due to the failure to collect the occupancy of the first section and the second section of the route, thereby avoiding the safety risks caused by the misjudgment and improving the safety of route handling and train scheduling.

[0058] According to some specific embodiments of the present invention, the method may further include: during the timing of the opening delay, obtaining the axle counter detection data of the route where the target signal machine is located;

[0059] Among them, the target route has and only has a fault-locked section in the target route that does not meet the signal opening conditions, including: if the axle counter detection data does not change, it is determined that there is no train occupying the fault-locked section of the target route where the target signal machine is located;

[0060] The conditions for opening any route other than the fault-locked section are not met, including: if the axle counter detection data changes, it is determined that the fault-locked section of the target route where the target signal is located is occupied by a train.

[0061] Among them, the fault-locked section occupied by a train means that there is a train running in the fault-locked section, and other trains are not allowed to enter the section to avoid train rear-end collision accidents. The fault-locked section is not occupied by a train, which means that there is no train running in the fault-locked section at present, and other trains are allowed to enter the section. The axle counter is used to determine whether the train passes through the route, especially the fault-locked section. When the open delay timing is triggered, the detection data of the axle counter of the fault-locked section in the route begins to be obtained. If no data change is detected, it means that the fault-locked section of the target route where the target signal is located is not occupied by the train. It can be judged that the fault-locked section is not caused by the occupation of the train, and other trains can enter the route; on the contrary, if the data of the axle counter of the fault-locked section in the target route where the target signal is located changes, it means that the fault-locked section is occupied by a train. In other words, a train is currently passing through the fault-locked section, and other trains cannot enter the target route. Whether the faulty locked section is occupied by a train is determined by observing the change in the detection data of the axle counter of the faulty locked section within the preset time of the opening delay. The occupancy status of the faulty locked section can be obtained simply and accurately, so that the target signal (i.e. the signal at the beginning of the route) can be accurately controlled to reopen the signal or keep it closed.

[0062] Optionally, the preset duration is obtained based on the time from the axle counter detection section being cleared to occupied, the engine electronic controller (Engine Electronic Control, EEC) operating cycle, the timeout time of the EEC and the element control computer (Element controlcomputer, ECC), the ECC operating cycle, and the timeout time of the ECC and CI.

[0063] Optionally, the three-point check unlocking time within the route can also be modified to the preset duration.

[0064] Optionally, the preset duration ranges from 4.5s to 5.5s.

[0065] Further optionally, the preset duration is about 5s. The preset duration of about 5s includes the time from axle counting clearing to occupation of 1000ms, the EEC operation cycle of 160ms, the EEC and ECC timeout of 600ms, the ECC operation cycle of 200ms, and the ECC and CI timeout of 2600ms, that is, 1000ms+160ms+600ms+200ms+2600ms=4560ms≈5s. The above preset duration of about 5s takes into account all delays, so 4560ms is the maximum delay time from axle counting clearing to occupation.

[0066] Of course, the preset duration is configurable and is not limited to the above range and the above value.

[0067] According to some embodiments of the present invention, determining that the target signal is a route start signal includes:

[0068] Traverse all the internal routes of the computer interlocking system;

[0069] Compare the identity information of the signal machines on all routes with the identity information of the target signal machine;

[0070] If the identity identification information of the starting signal of any of the above-mentioned routes is consistent with the identity identification information of the target signal, the target signal is determined to be the starting signal of the route.

[0071] Among them, when the signal restart command of the target signal is received and it is determined that the target signal is in the closed state, it is necessary to determine whether the target signal is the route start signal. Each signal has its specific identity identification information. Whether the target signal is the route start signal can be determined by matching the identity identification information. The computer interlocking system records the route inside it and the identity identification information of the start signal of each route. The identity identification information of the route start signal inside the computer interlocking system can be compared with the identity identification information of the target signal one by one. If the identity identification information of the start signal of a route inside the computer interlocking system is consistent with the identity identification information of the target signal, the target signal is determined to be the start signal of the route. By comparing the identity identification information of the route start signal inside the computer interlocking system with the identity identification information of the target signal to determine whether the target signal is the route start signal, the accuracy of determining that the target signal is the route start signal can be improved, and this method is simple and effective.

[0072] Furthermore, the method may further include: when it is determined that the direction of the faulty locked section is inconsistent with the route direction, controlling the target signal to maintain a closed state. Specifically, if the route direction is an upward direction and the direction of the faulty locked section is a downward direction, or the route direction is a downward direction and the direction of the faulty locked section is an upward direction, both directions of the faulty locked section and the route direction are inconsistent. When it is determined that the direction of the faulty locked section and the route direction are inconsistent, controlling the target signal to maintain a closed state can ensure driving safety.

[0073] Furthermore, after receiving the signal restart instruction of the target signal, the above method may also include: determining that the target signal is in an open state, and then controlling the target signal to maintain the open state. Specifically, after receiving the signal restart instruction of the target signal, if the target signal is in an open state, it means that there is no fault locked section in the route where the target signal is located, that is, there is no equipment failure in the route, and there is no train occupying the route, then the target signal can be controlled to maintain the signal open state to indicate that other trains can enter the route. This arrangement can ensure the normal handling of the route when there is no fault locked section in the route, that is, when the route is normally locked.

[0074] According to some embodiments of the present invention, after controlling the target signal machine to turn on the signal again, the method may further include:

[0075] Periodically perform route open condition checks;

[0076] If it is determined that the route where the target signal is located does not meet the conditions for opening the route, the target signal will be controlled to be closed.

[0077] Specifically, at fixed time intervals, the target signal is checked to see if it meets the route opening conditions, and when it is determined that the target signal does not meet the route opening conditions, the target signal is controlled to close. This can prevent trains from entering the route when the route does not meet the route opening conditions, thereby improving driving safety.

[0078] In some embodiments of the present invention, whether the route opening condition (which can be expressed as RTSCI-SWRS-23*) is met is determined as follows:

[0079] - The CI and the Zone Controller (ZC) are communicating normally and the ZC provides no train approaching information; or

[0080] -CI and ZC communicate normally and ZC provides the approaching information of the uncommunication train (UT); or

[0081] -CI and ZC communicate normally and ZC provides the approaching information of the communication train, i.e. AT (automatic train), and the route is configured with non-CBTC (Communication Based Train Control) route attributes (according to no train approaching); or

[0082] -CI and ZC are communicating normally and the starting signal is a shunting signal (approaching according to UT); or

[0083] -CI and ZC communication interrupted.

[0084] Optionally, when there is no train approaching, there is no need to check the integrity of the red filament of the approach start signal. Instead, the following conditions need to be checked according to the interlocking table configuration of the computer interlocking system:

[0085] - Check that the route is not within the delay time of the manual unlocking route, zone unlocking, red light tolerance (cancelling manual unlocking), guided stop timing, or guided route or guided general lock opening signal red light tolerance;

[0100] - The emergency stop button is not pressed; and

[0101] - The vehicle has not been impounded; and

[0102] - platform doors closed or bypassed; and

[0108] - the charging pantograph (if present) is raised; and

[0109] - the vault door (if any) is open; and

[0110] -Car wash machine (if any) is in standby mode.

[0111] Optionally, when the CI and ZC communication connections are normal, AT train approach information is provided, the route is configured with AT route attributes, and the starting signal is not a shunting signal, the route opening needs to check the following conditions (configured according to the interlocking table):

[0112] - Check that the route is not within the delay time of the manual unlocking route, zone unlocking, red light tolerance (cancelling manual unlocking), guided stop timing, or guided route or guided general lock opening signal red light tolerance;

[0113] - All sections in the route are not fault locked, not powered on and not boot locked; and

[0114] - All sections within the route are locked normally (the locking direction is consistent with the route direction); and

[0115] - All sections within the route are not locked or locked (in the same direction as the route); and

[0116] - the switches in the approach (if any) are in the expected positions; and

[0120] -The first logical section in the route is free;

[0121] - Hostile route (if any) is not established (hostile route established: hostile route has been processed and hostile signals are open and switches are in expected positions); and

[0131] -Car wash machine (if any) is in standby mode.

[0132] Optionally, after the route start signal is opened, the following judgment is made:

[0133] ①The return rail is not the bulb line:

[0134] - If the route is down, check that the first section outside the route start signal is an up return track (or up + down) and is locked and occupied, then lock the section to be consistent with the route direction;

[0135] - If the route is upward, check that the first section outside the signal at the beginning of the route is a downward return track (or upward + downward) and is locked and occupied, then lock the section to be consistent with the route direction;

[0138] - If the route is down, check whether the first section outside the signal at the beginning of the route is an up return track (or up + down) and is locked and occupied;

[0139] - If the first section of the route has the bulb line attribute and the bulb line attribute of the return track is consistent, then the section will be locked in the opposite direction of the route.

[0140] - Otherwise, lock the section to the same direction as the approach;
