Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a station interlocking logic processing method, including the following steps:
s101, performing small route virtualization processing on a station route;
s102, after a new route sequence table is obtained, judging whether the obtained route sequence table is changed or not, and if the obtained route sequence table is changed progressively relative to the existing route sequence table, carrying out interlocking processing on all route commands which are not sent out and allowed to enter authorization in the obtained route sequence table one by one; if the obtained route sequence table is changed in path relative to the existing route sequence table, unlocking all routes in the station, sending permission for canceling the idle permission of the routes to the train control system, and interlocking each route command in the route sequence table one by one;
s103, after detecting that the train sequentially occupies the clear access, sending permission for canceling the access idle permission to enter to the train control system; judging whether the small route appears in a subsequent route in the current route sequence list or not, and locking or unlocking the small route again after locking or unlocking according to the judgment result; for small routes that remain locked and re-locked, the nematic system is given permission for its idle admission.
Fig. 1 is a schematic flow chart of a station interlocking logic processing method provided by the present invention, wherein performing small route virtualization processing on a route and obtaining a route sequence table by an interlocking system are basic conditions for implementing the method. The station interlocking logic takes a small route as a unit, takes a received new route sequence list and the train sequence occupying the clear route as system work trigger points, carries out protection processing on the small route, and can also carry out protection processing on the route subjected to the existing interlocking processing. The method for protecting and processing the small access by the interlocking system can be the same as the existing method for protecting and processing the access, and the interlocking checking conditions comprise whether the turnout position of the small access is correct, whether an enemy access is established, the checking conditions of the interlocking section, the section blocking conditions, whether the section is idle or not and the like.
Fig. 2 is a schematic diagram of virtualization processing for making a small route to a route, taking a simple station throat area as an example. Optionally, in this embodiment, a track circuit is used as a unit to set a small route. For a small route formed by a section 1 in the figure, a virtual signal machine is arranged for each entrance, namely three virtual signal machines 1a, 1b and 1c, wherein the entrance 1a can be an entrance/exit, a real entrance/exit signal machine can be arranged, and the entrance/exit port can be set with blocking detection conditions; similarly, for the small route formed by the section 3, besides setting a virtual signal machine for each entrance, it can also set the checking condition of the outbound stock track for the 3b and 3c entrances, and in addition, it can set the switch position selection or checking condition of driving, protection and so on for the section with driving, protection and so on requirements. After each small route of the whole station is set, the interlocking system can decompose the current route in the process of processing the current route, so that each small route forming the current route and the virtual protection annunciator of each small route are determined. For example, in fig. 2, the current routes are A, B at their respective ends, the interlock system decomposes the current routes into a small route 1(1 a-section 1-1c), a small route 2(2 a-section 2-2b), and a small route 3(3 a-section 3-3b), and determines good virtual guard signals for each small route, for example, the virtual guard signal of the small route 1 is 1a, the small route 2 is 2a, and the small route 3 is 3a, the interlock system can process the 3 small routes respectively, and perform switch position selection and interlock condition check for each small route, and after the 3 small routes are all successfully locked, the interlock system can set the current route to be locked and open the real signal.
It should be noted that the virtual semaphore is not a real physical entity, but is a virtual logical unit. And decomposing each route command in the route sequence list according to the starting terminal and the route thereof, and dividing the route command into small routes protected by the virtual signal machine one by one.
The route sequence list is composed of one or a plurality of route commands, and each route command comprises the route serial number of the current day, the starting terminal of the route and the information of the route key point. In order to improve the processing efficiency of the route, the route command in the route sequence list may at least include a route to a subsequent vehicle receiving port (or a vehicle departure port). The route sequence list is requested to be timed, or transmitted to the interlock system when a change in the route command occurs. The condition that the route command changes comprises that a certain route is occupied and cleared along with the running of the train, the route is completed, and the route sequence table deletes the completed route and supplements the route sequence table progressive condition of a new route; or when the information of the starting end or the terminal end of the route or the key point of the changed route in a certain route command in the route sequence list changes.
Alternatively, the route sequence list may come from a dispatch aggregation system, or other similar system that contains this information.
Fig. 3 is a flowchart illustrating a station interlock logic processing method when a new route sequence is received according to an embodiment of the present invention.
And when the interlocking system receives a new route sequence table, judging whether the route sequence table is subjected to progressive change or path change. An optional method is that a newly obtained route sequence table and an existing route sequence table of an interlocking system are compared, and if only occupied route commands in the existing route sequence table are deleted or route commands are newly added, and information of other routes in the existing route sequence table is not changed, the route sequence table can be judged to be changed progressively; if the information of other routes in the existing route sequence list is changed by the starting terminal or the changed route key point information except the deleted route name, the route sequence list is judged to be changed by the route.
If the interlock system judges that the progressive change of the route list occurs, processing each route command which does not send permission to enter authorization in the route list one by one; if the interlocking system judges that the route list path change occurs, all routes are unlocked, permission for canceling the idle admission of the routes is sent to the control system, and all route commands in the route list are processed one by one.
The interlocking processing process of the interlocking system to each route command comprises the steps of decomposing the current route into a plurality of small routes and selecting a target small route in an unlocking state; selecting the turnout position of the small target route according to the route starting terminal or the route key point changing information, and checking whether the target small route meets the interlocking checking condition; if the route is matched with the idle access permission, the small access is locked, the virtual annunciator for protecting the small access is opened, and the access idle permission entering permission is sent to the mobile blocking train control system. And opening an access protection annunciator after each small access virtual signal in the current access subjected to interlocking processing is opened, and giving access free permission for access to the column control system.
Fig. 4 is a schematic flow chart of the case where the small routes are sequentially occupied and cleared according to the embodiment of the present invention.
Aiming at each small route of the current route, after detecting that the route is occupied and is cleared, the interlocking system sends permission for allowing the route/small route to enter in an idle mode to the train control system; and simultaneously judging whether the small route appears in a subsequent route in the current route sequence list, keeping or unlocking the small route according to the judgment result, and giving the locked small route idle admission authorization to the train control system.
If the interlocking system judges that the small access occupied by the train to be cleared appears in the subsequent access of the current access sequence, the interlocking system checks whether the turnout position of the small access is coincident with the subsequent access requirement; if the positions are overlapped, the locking state of the small access is kept, the opening state of a virtual signal machine for protecting the small access is kept, and the permission of idle admission of the small access is given to a control system; if the positions are not coincident, unlocking the small route, carrying out turnout position selection and interlocking condition check on the small route according to the starting terminal of the subsequent route and the key point information of the changed route, then carrying out selection, car detection and locking on the small route, opening a small route virtual signal, and giving authorization for idle access of the small route to a train control system.
And if the interlocking system judges that the small access which is taken out by the train does not appear in the subsequent access in the current access sequence list, the interlocking system unlocks the small access.
The small access unlocking method is different from the access unlocking method of the existing station interlocking logic processing method, and by applying the embodiment of the invention, after the train is detected to be sequentially occupied and cleared, the small access is not unlocked necessarily, but is selectively kept locked or unlocked and then kept locked or unlocked again according to the traveling path of the subsequent access, and for the small access kept locked, the interlocking system can directly send the permission of idle access of the small access to the mobile blocking train control system to indicate that the small access is allowed to be accessed by the subsequent train. The method can reduce the frequency of interlocking locking and unlocking the route, shorten the time for handling the route in the station, realize that the target point of the subsequent train approaches to the front train tail as much as possible, and improve the train tracking efficiency of the following control system in a mobile block mode.
Illustratively, as shown in fig. 2, if the end of the current route is a-B and the starting terminal of the next route of the current route is a-C, when the train occupies the small route 1 in sequence, the interlock system issues an authorization to cancel the idle allowed route of the conventional route and the small route 1, and issues the authorization to cancel the idle allowed route of the small route 2 and the small route 3 as the train occupies the small route 1(1 a-section 1-1C), the small route 2(2 a-section 2-2B) and the small route 3(3 a-section 3-3B) in sequence, and each small route has different positions according to the section and the switch point where it is located, and the subsequent locking and unlocking conditions have different treatments under different conditions.
For the small access 1 and the small access 2, because the small access 1 and the small access 2 are both in the next access, and the requirements of the next access on the turnout positions of the small access 1 and the small access 2 are consistent with the current access, after the small access is cleared, the interlocking system can keep the locking state of the small access 1 and the small access 2, keep the virtual annunciators protecting the small access 1 and the small access 2 in the open state, send the section free permission access permission of the small access 1 and the small access 2 to the mobile blocking train control system, and ensure that the mobile authorization terminal of the subsequent train approaches to the tail of the front train as soon as possible.
For the small route 3, although the small route is present in the next route, the switch positions of the small route 3 in the current route and the next route are not consistent, the interlocking system can unlock the small route 3 first, and after the switch positions are converted to the positions required by the next route, the interlocking condition check is carried out, if the interlocking condition is met, a virtual signal machine for protecting the small route 3 is opened, the small route 3 is locked, and the small route 3 section idle admission permission is sent to the mobile blocking train control system.

Loutbound throatThe distance from the outbound signal machine to the reverse inbound signal machine is represented;
La leavingRepresents the length of a leaving (1LQ) segment;
With the station interlocking logic processing method of the invention, as the preceding train runs, one small route can be operated, condition checked and kept locked when the train occupies the next small route, and considering the train length (such as 200m), the length (such as 50m) of the small route and the lateral train receiving speed (such as the speed 80km/h is (200+50)/(80/3.6) ═ 11.25s), one small route operation, condition checked and kept locked can be basically completed in the next small route running time, therefore, the train arrival interval I 'of the invention'ToAnd train departure interval I'Hair-like deviceAnd train passing interval I'Tong (Chinese character of 'tong')Respectively as follows:
