Description

TECHNICAL FIELD

[0001] The present application relates to the field of rail transit, and in particular to a route section unlocking method, an interlocking system and a computer readable storage medium. BACKGROUND

[0002] In the related art, for the train cross-pressure lamp-off mode, specifically, the regional controller obtains the position of the cross-pressure signal of the train, and sends the cross-pressure signal command to the interlocking system, and the interlocking system sets the corresponding signal to the prohibited signal according to the received cross-pressure signal command. For the signal cross-pressure command calculation mode, specifically, the signal position and the occupation information of the signal outer section are obtained according to the regional control signal system, and according to the train occupation section condition and the signal position information, when the train head is in the signal inner section and the train tail is in the signal outer section, it is determined that there is signal cross-pressure.

[0003] However, the cross-pressure signal command in the above two modes is sent to the interlocking system by the regional controller, and since the regional controller judges the possible position of the train to be real-time change, only a certain range of possible train can be given, and the communication delay between the regional controller and the train will also increase the range of the position of the train, so too much trust is given to the train position sent by the regional controller, and when the train is degraded and non-communication, the judgment of the cross-pressure is insufficient. At the same time, in this case, the cross-pressure information of the corresponding signal received by the interlocking system is unstable, and such unstable signal cross-pressure information cannot meet the requirements of the unlocking of the route inner section. SUMMARY

[0004] The present application aims to at least solve one of the technical problems in the prior art. To this end, one object of the present application is to provide a route section unlocking method, which can enable the interlocking system to determine the cross-pressure information of the route to which the section belongs without relying on the regional controller, and improve the stability of the cross-pressure information received by the interlocking system.

[0005] A second object of the present application is to provide an interlocking system.

[0006] A third object of the present application is to provide a computer readable storage medium.

[0007] To solve the above problems, the first aspect of the present application provides a method for route section unlocking, the method comprising: acquiring occupation states of front and rear sections of a home signal, wherein the home signal is located at a starting point of a route that has been handled, and a section to be unlocked belongs to the route that has been handled; determining a cross-pressure state of the route that has been handled according to the occupation states; obtaining a switch position in the route that has been handled; and judging whether the section to be unlocked meets an unlocking cross-pressure condition according to the cross-pressure state and the switch position, and unlocking the section to be unlocked if the section to be unlocked meets the unlocking cross-pressure condition.

[0008] According to the method for route section unlocking provided by the embodiment of the present application, the occupation states of the front and rear sections of the home signal when the train crosses the home signal are checked by the interlocking system, so that the cross-pressure state of the route that has been handled to which the section to be unlocked belongs can be obtained, thereby avoiding the problem of instability of the cross-pressure information received by the interlocking system and avoiding the need to rely on the cross-pressure information provided by the area controller, and the interlocking system judges whether the section to be unlocked meets the unlocking cross-pressure condition according to the cross-pressure state and the switch position, which is more conducive to the unlocking control of the section to be unlocked in the route that has been handled by the interlocking system and can ensure that the train travels in the locked section to the greatest extent.

[0026] The embodiments of the present application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary, and the embodiments of the present application are described in detail below.

[0027] To solve the above problems, the first aspect of the present application provides a method for unlocking the route section, by which the interlocking system can determine the cross-pressure information of the route to which the section to be unlocked belongs without relying on the area controller, and improve the stability of the interlocking system in receiving the cross-pressure information.

[0028] The embodiments of the present application are described below with reference to Figure 1 The method for unlocking the route section provided by the embodiments of the present application is described, which is used in an interlocking system, as shown in Figure 1 The method at least includes steps S1-S4.

[0029] Step S1, obtaining the occupation states of the front and rear sections of the start signal, wherein the start signal is located at the start point of the route that has been handled, and the section to be unlocked belongs to the route that has been handled.

[0030] Wherein, there is one or several physical sections between the start signal and the end signal of the route, and the signals are distributed at the axle counting points. When the sections are divided, for non-CBTC (Communication Based Train Control) trains and traditional trains, the axle counting section mode is adopted; for CBTC trains, the axle counting section is divided into several shorter logical sections. The section to be unlocked is the section that has been occupied by the train in the route that has been handled and is then cleared. The occupation state of the section refers to whether the train is running on the section. If the train is running on the section, the section is in the occupied state; if the train is not running on the section, the section is in the idle state or the arbitrary state.

[0031] In the interlocking system, the two ends of the section in the route that has been handled are respectively provided with trackside train occupation detection equipment for counting the number of wheels of the train passing through the two ends of the route section, so as to determine the section where the train is currently located. Thus, through the communication between the interlocking system and the trackside train occupation detection equipment, the occupation states of the front and rear sections of the start signal in the route that has been handled can be obtained.

[0032] Step S2, determining the cross-pressure state of the route that has been handled according to the occupation states.

[0033] Wherein, the cross-pressure state refers to whether the train on the inner side of the start signal is safely enveloped on the start signal. If it is determined that there is a cross-pressure state, it means that the train on the inner side of the start signal has entered the route that has been handled; if it is determined that there is no cross-pressure state, it means that the train on the inner side of the start signal has not entered the route that has been handled.

[0034] In the embodiment, when the interlocking system detects the train entity cross-pressure, the occupation and idle change of the first section on the inner side of the start signal and the front section on the outer side are mainly checked. When the signal is opened, the interlocking system can directly determine whether the train truly crosses the start signal and enters the section protected by the start signal according to the occupation and idle state changes of the front and rear sections of the start signal collected by the interlocking system, so as to avoid the problem of unstable cross-pressure information received by the interlocking system, and make the interlocking system also accurately obtain the cross-pressure information of the train in the case of train degradation and non-communication control level train, thereby improving the usability of the interlocking system.

[0035] Step S3, obtaining the position of the turnout in the route that has been handled.

[0036] The turnout is a device for turning a train from one track to another track, and different turnout positions make the vehicle enter different routes. The turnout position includes a normal position and a reverse position. If the turnout is located in the route, the turnout is in the normal position. If the turnout is not located in the route, the turnout is in the reverse position.

[0037] In the interlocking system, the turnout detection device is arranged at the turnout of the route. The position of the turnout in the route entering the to-be-unlocked section can be obtained through communication between the interlocking system and the turnout detection device.

[0038] In step S4, it is judged whether the to-be-unlocked section meets the unlocking cross-pressure condition according to the cross-pressure state and the turnout position. If yes, the to-be-unlocked section is unlocked.

[0039] After the to-be-unlocked section is unlocked, the section is in a usable state, so as to be used or called by other trains. If the section is in a locked state, other trains cannot use or call the section.

[0040] In the embodiment, the unlocking of the route section mainly adopts a three-point checking method. In the three-point checking unlocking process, the signal cross-pressure is one of important conditions for the three-point checking unlocking of the section. The cross-pressure state of the route in which the to-be-unlocked section is located is determined by the interlocking system according to the occupancy state, and the cross-pressure condition checking of the to-be-unlocked section is finally determined according to the cross-pressure state and the turnout position. In this way, the unlocking control of the to-be-unlocked section in the route by the interlocking system is more favorable, and the train running in the locked section is more guaranteed.

[0041] According to the route section unlocking method, the occupancy states of the front section and the rear section of the train cross-pressure signal are checked by the interlocking system, so that the cross-pressure state of the route in which the to-be-unlocked section is located is obtained, thereby avoiding the problem of unstable cross-pressure information received by the interlocking system, and the to-be-unlocked section is determined to meet the unlocking cross-pressure condition according to the cross-pressure state and the turnout position, which is more favorable for the unlocking control of the to-be-unlocked section in the route by the interlocking system, and the train running in the locked section is more guaranteed.

[0042] In some embodiments, the interlocking system detects that the start signal is open. If it is determined that the front section is occupied and the rear section is idle at the current time, and it is determined that the front section is occupied and the rear section is occupied at the next time, it is determined that the route has cross-pressure.

[0043] Specifically, the interlocking system determines the cross-pressure of the handled route by the open state of the above home signal and the occupation and idle state changes of the front and rear sections. If the interlocking system first detects that the front section of the home signal is occupied and the rear section is idle under the premise that the home signal is open, and then detects that the front section is occupied and the rear section is occupied, it can be determined that the train has truly crossed the home signal and entered the section protected by the home signal, that is, it is determined that the handled route has cross-pressure; otherwise, the interlocking system determines that the train has not truly crossed the home signal and entered the section protected by the home signal according to the collected open state of the home signal and the occupation and idle state changes of the front and rear sections, that is, it is determined that the handled route has no cross-pressure, for example, the interlocking system detects that the home signal is not normally open, which indicates that the home signal may have a fault, and in this case it is determined that the handled route has no cross-pressure. Thus, the interlocking system does not need to rely on the cross-pressure information provided by the area controller in the process of judging the occupation and idle state changes of the front and rear sections of the home signal, avoiding the problem of instability of the cross-pressure information received by the interlocking system, making the interlocking system applicable to the case of train degradation and non-communication control level train, and improving the availability of the interlocking system.

[0044] In some embodiments, the interlocking system determines that the handled route has no cross-pressure, which indicates that the train inside the home signal has not normally entered the handled route, such as the train has not entered the handled route or the train has entered the handled route by breaking the red light. Therefore, in order to avoid the case that the handled route is used by the train outside the home signal and affects the normal driving of the train inside the home signal, the interlocking system determines that the to-be-unlocked section does not meet the unlocking cross-pressure condition in the handled route, that is, controls the to-be-unlocked section to be in a locked state, to ensure the normal driving of the train inside the home signal and improve the availability of the interlocking system, regardless of whether the turnout in the to-be-unlocked section is in place or not.

[0045] In some embodiments, the interlocking system determines that the handled route has cross-pressure, and determines that the turnout in the to-be-unlocked section in the handled route is in place, which indicates that the train inside the home signal has normally entered the handled route. Therefore, the to-be-unlocked section meets the unlocking cross-pressure condition in the handled route, so that the to-be-unlocked section is controlled to be unlocked after meeting the remaining unlocking conditions, to be used or called by other trains, and the availability of the interlocking system is improved.

[0046] In some embodiments, the interlocking system determines that the route has a cross pressure, and determines that the switch inside the route into the section to be unlocked is in the reverse position, then the section to be unlocked maintains the unlocked cross pressure condition in the route, that is, does not change the unlocked cross pressure condition of the section to be unlocked. For example, if the last time the section to be unlocked is determined to satisfy the unlocked cross pressure condition, then after the determination of the unlocked cross pressure condition this time, the section to be unlocked maintains the unlocked cross pressure condition, that is, it is determined that the section to be unlocked still satisfies the unlocked cross pressure condition. Conversely, if the last time the section to be unlocked is determined to not satisfy the unlocked cross pressure condition, then after the determination of the unlocked cross pressure condition this time, the section to be unlocked maintains the unlocked cross pressure condition, that is, it is determined that the section to be unlocked still does not satisfy the unlocked cross pressure condition.

[0047] In some embodiments, due to the existence of multiple lines interlaced in the actual running line, in this case, there is a problem that the section to be unlocked belongs to multiple routes. The section to be unlocked is located behind the switch, that is, in the direction from the starting signal to the terminal signal, when the train normally travels in the route, it will first pass through the switch in the route and then enter the section to be unlocked. For example, Figure 1 As shown, if the route S1-S3 and the route S2-S3 are in the processed state, the train sequentially enters and leaves the section PT6 from the processed route, the section PT6 triggers the three-point check delay unlocking, the section PT6 is the section to be unlocked, the section PT6 belongs to two processed routes, and in the direction from the starting signal S1 to the terminal signal S3, the section PT6 is located behind the switch P1. Therefore, when performing the unlocking check on the section to be unlocked, the cross pressure information of all the processed routes to which the section to be unlocked belongs needs to be considered comprehensively to avoid problems in the cross pressure check condition of the route to which the section to be unlocked belongs.

[0048] Specifically, for the section to be unlocked located behind the switch, when the processed route is multiple and the section to be unlocked belongs to multiple processed routes, the interlocking system first determines the cross pressure state of each processed route according to the occupation state of each processed route, and obtains the switch position in each processed route, and then determines the unlocked cross pressure condition of the section to be unlocked in each processed route according to the cross pressure state of each processed route and the switch position in each processed route. According to the unlocked cross pressure condition of all the processed routes to which the section to be unlocked belongs, it is determined whether the section to be unlocked satisfies the unlocked cross pressure condition, that is, the interlocking system comprehensively checks the unlocked cross pressure condition of the section to be unlocked in each processed route, and determines the actual unlocked cross pressure condition of the section to be unlocked according to the final check result, which is more conducive to the unlocking of the section in the route in the CBTC multi-train tracking process, and can also maximize the guarantee of the train traveling in the locked section.

[0049] In some embodiments, when the to-be-unlocked section belongs to multiple routes with handled progress, the interlocking system directly sets the final check result of the to-be-unlocked section as meeting the unlocking cross-pressure condition when determining that any one of the routes with handled progress to which the to-be-unlocked section belongs has cross pressure and the switch entering the to-be-unlocked section in the any one of the routes with handled progress is in the normal position, without checking the unlocking cross-pressure conditions of the remaining routes with handled progress, and then the any one of the routes with handled progress controls the to-be-unlocked section to be unlocked after meeting the remaining unlocking conditions, so as to be used or called by other trains, thereby improving the availability of the interlocking system.

[0050] The method for unlocking the route section according to the embodiments of the present application is described in detail below by taking the case that the to-be-unlocked section belongs to two routes with handled progress, wherein the two routes with handled progress include a first route with handled progress and a second route with handled progress, and the to-be-unlocked section belongs to the first route with handled progress and the second route with handled progress.

[0051] Specifically, if the to-be-unlocked section meets the unlocking cross-pressure condition in the first route with handled progress and does not meet the unlocking cross-pressure condition in the second route with handled progress, the final check result of the to-be-unlocked section is that the to-be-unlocked section meets the unlocking cross-pressure condition; or the to-be-unlocked section meets the unlocking cross-pressure condition in the first route with handled progress, and the to-be-unlocked section maintains the unlocking cross-pressure condition in the second route with handled progress, that is, the check result of the to-be-unlocked section in the second route with handled progress does not change the unlocking cross-pressure condition of the to-be-unlocked section, and the to-be-unlocked section still meets the unlocking cross-pressure condition in the second route with handled progress, so the final check result of the to-be-unlocked section is that the to-be-unlocked section meets the unlocking cross-pressure condition; or the to-be-unlocked section does not meet the unlocking cross-pressure condition in the first route with handled progress, and the to-be-unlocked section maintains the unlocking cross-pressure condition in the second route with handled progress, that is, the check result of the to-be-unlocked section in the second route with handled progress does not change the unlocking cross-pressure condition of the to-be-unlocked section, and the to-be-unlocked section still does not meet the unlocking cross-pressure condition in the second route with handled progress, so the final check result of the to-be-unlocked section is that the to-be-unlocked section does not meet the unlocking cross-pressure condition.

[0052] The following describes the method for unlocking the route section according to the embodiments of the present application in detail below by taking the case that the to-be-unlocked section belongs to two routes with handled progress, with reference to the accompanying drawings. Figure 2 and the accompanying drawings. Figure 3 The following describes the method for unlocking the route section according to the embodiments of the present application in detail below by taking the case that the to-be-unlocked section belongs to two routes with handled progress, with reference to the accompanying drawings.

[0053] For example, as shown in FIG. 1, the to-be-unlocked section is a section 1, the first route with handled progress is a route 1, and the second route with handled progress is a route 2. Figure 2The figure shows a schematic diagram of multiple routes with the same terminal but different starting points for a train. The train enters section PT6 from section PT3 or section PT1 and leaves section PT6. At this time, section PT6 will trigger a three-point inspection and delayed unlocking. If the inspection results of the three-point inspection and unlocking cross-pressure conditions of section PT6 are as follows: the upward route S2-S3 is processed, the starting signal S2 is open, and the train enters section PT6 normally from route S2-S3; sections PT4 and PT5 trigger three-point inspection and unlocking. At this time, the route S2-S3 belonging to section PT6 has normal cross-pressure information; sections PT4 and PT5 are unlocked successfully, and the route S1-S3 is processed. The switch P1 is turned to the reverse position. At this time, the route S1-S3 belonging to section PT6 has no normal cross-pressure information; at this time, the switch P1 is in the reverse position, section PT6 belongs to two processed routes, and train T1 leaves section PT6. Based on the above inspection, it can be determined that there is no cross-pressure on the processed route S1-S3 and the switch is in place, that is, the unlocked section PT6 on the processed route S1-S3 does not meet the unlock cross-pressure condition. Furthermore, there is cross-pressure on the processed route S2-S3 and the switch is not in place, that is, the unlocked section PT6 on the processed route S2-S3 meets the unlock cross-pressure condition. Therefore, the interlocking system determines that the cross-pressure condition check of section PT6 has failed in the three-point inspection, and section PT6 does not meet the unlock cross-pressure condition. At this time, section PT6 is re-locked by the processed route S1-S3, and it is in accordance with the actual requirements to not unlock section PT6.

[0054] like Figure 2 As shown, the train enters section PT6 from section PT3 or section PT1 and leaves section PT6. At this time, section PT6 will trigger a three-point inspection delayed unlocking. If the inspection results of the three-point inspection unlocking cross-pressure conditions of section PT6 are as follows: the up route S2-S3 is processed, the starting signal S2 is open, and the train enters section PT6 normally from route S2-S3; sections PT4 and PT5 trigger three-point inspection unlocking. At this time, the route S2-S3 belonging to section PT6 has normal cross-pressure information; sections PT4 and PT5 are unlocked successfully, the route S1-S3 is processed, and the switch P1 is turned to the reverse position. At this time, the route S1-S3 belonging to section PT6 has no normal cross-pressure information; at this time, the switch P1 is in the reverse position, and the manual section releases section PT5, and turns the switch P1 to the positioned position. Section PT6 belongs to two processed routes, and train T1 leaves section PT6. Based on the above inspection, it can be determined that there is no cross-pressure on the processed route S1-S3 and the switch is not in place, that is, the unlocked section PT6 does not meet the unlocking cross-pressure conditions on the processed route S1-S3. Furthermore, there is cross-pressure on the processed route S2-S3 and the switch is in place, that is, the unlocked section PT6 meets the unlocking cross-pressure conditions on the processed route S2-S3. Therefore, the interlocking system determines that the cross-pressure condition check of section PT6 in the three-point check is successful. Section PT6 can be unlocked after meeting the remaining unlocking conditions. When the switch is turned to the fixed position, section PT6 can be used as the unlocked section of the processed route S2-S3, and unlocking section PT6 meets the actual requirements.

[0055] like Figure 3 The figure shows a schematic diagram of multiple routes for trains entering different terminals at the same starting point. After train T2 enters section PT11 or section PT10 from section PT7 and leaves section PT11 or section PT10, section PT11 and section PT10 will trigger a three-point inspection delay unlock. If the three-point inspection unlock cross-pressure condition of section PT10 and section PT11 is checked, the upward route S5-S6 is processed, the starting signal S5 is open, and the train is processed by the entry signal. Train S5-S6 enters section PT10 normally. Section PT9 triggers a three-point check and unlocks. S5-S6, the route to which section PT10 belongs, now has normal cross-traffic pressure information. Section PT9 successfully unlocks, and S5-S7, the route to which section PT9 belongs, is unlocked. Turnout P2 is reversed, and S5-S7, the route to which section PT9 belongs, now has no normal cross-traffic pressure information. Turnout P2 is reversed, and section PT9 belongs to two routes. Train T2 departs section PT10. Based on these checks, it is confirmed that S5-S6, the route to which section PT10 belongs, has cross-traffic pressure, and turnout P2 is not in place. The cross-traffic pressure condition check for section PT10's three-point check is successful, and section PT10 can be unlocked once the remaining unlocking conditions are met. The routes to which section PT10 belongs have normal cross-traffic pressure, and unlocking section PT10 meets actual requirements.

[0056] like Figure 3 As shown, after train T2 enters section PT11 or section PT10 from section PT7 and leaves section PT11 or section PT10, section PT11 and section PT10 will trigger the three-point inspection delayed unlocking. If the inspection status of the three-point inspection unlocking cross-pressure condition of section PT10 and section PT11 is: the up route S5-S6 is handled, the signal S5 is not open, the train runs a red light from route S5-S6 and enters section PT10, and route S5-S6 has been handled There is no normal cross-pressure; Section PT9 is manually unlocked, and at this time, the S5-S6 route belonging to Section PT10 has no normal cross-pressure information. Section PT9 is successfully unlocked, and the S5-S7 route is opened. Switch P2 is switched to the reverse position, and the starting signal S5 opens. The second train enters S5-S7 normally from PT7, entering Section PT11. At this time, switch P2 is in the reverse position, and the S5-S7 route belonging to Section PT9 has normal cross-pressure information, and the second train leaves Section PT11. Based on the above inspection, it can be determined that the S5-S6 route that has been processed has no cross-pressure and switch P2 is not in place, and the S5-S7 route that has been processed has cross-pressure and switch P2 is in place. Section PT9 belongs to two processed routes, and the cross-pressure condition check of Section PT9 is successful in the three-point check. Section PT11 belongs to one processed route, and the cross-pressure condition check of Section PT11 is successful in the three-point check. Sections PT9 and PT11 can be unlocked after the other unlocking conditions are met.

[0057] It should be noted that when the number of routes to which the to-be-unlocked section belongs is different and the position of the route switch inside the route changes, similar to the content of determining the unlocking cross pressure condition when the to-be-unlocked section belongs to two routes, in order to reduce redundancy, the specific description is not given here.

[0058] In summary, according to the method for unlocking the route section provided in the embodiments of the present application, when the signal is an open signal, the interlocking system can determine the cross pressure information of the to-be-unlocked section belonging to the route by the occupancy state of the sections before and after the signal, without relying on the cross pressure determination of the area controller, thereby improving the availability of the signal system in the non-CBTC mode. In addition, in the three-point check unlocking process, if the to-be-unlocked section in the route belongs to multiple routes, on the basis of the original signal cross pressure determination technology, the cross pressure information of the multiple routes is comprehensively considered to finally determine whether the to-be-unlocked section meets the unlocking cross pressure condition, thereby being more conducive to the unlocking of the section in the route in the CBTC multi-train tracking process, and also being able to maximize the guarantee of the train running in the locked section.
