Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a side impact protection method and a side impact protection system.
Background
Side impact Protection (Flank Protection) is an important factor in ensuring train operation safety in railway signaling systems. The purpose of the system is to prevent a certain train in a route from colliding with other trains outside the route, and the system mainly realizes protection by locking related side turnouts to a direction far away from a target route, lighting up and prohibiting lights of a checking side signal prevention machine, confirming that a side rail prevention section is unoccupied and the like, so as to ensure the running safety of the trains in different station operation scenes.
However, no matter what side protection condition configuration is adopted, the existing side protection implementation mode is mainly focused on side impact protection under each running scene in the station, the influence on the operation safety in the station when the train runs in the section is not considered, and in some cases, the risk that the train breaks into a target approach from the relevant section port and side impact occurs exists.
Disclosure of Invention
Aiming at the problems, the invention provides a side impact protection method and a side impact protection system for realizing section side impact protection during operation in a train station.
In a first aspect, a method of side impact protection is provided. The method comprises the following steps: and acquiring a target route in the station, determining that the side protection condition of the target route section is met based on the section direction related to the side protection of the target route, locking the target route and opening a signal.
In one possible design, the interval side protection condition may include: the section direction of the side guard section opening is the vehicle receiving direction, and one of the following is as follows: the outside approaching section of the side defense area entrance station annunciator is idle; or the occupied time of the outside approach section of the entrance signal machine of the side defense area is more than or equal to the preset time. The target route side prevention section opening is a section opening with side impact risk with the target route.
That is, when the inter-side entrance direction is the pickup direction, the outer approach section of the inter-side entrance traffic signal is not occupied, that is, the train traveling to the target access station in the inter-side entrance is not yet approaching. Or, the other trains are stopped outside the entrance signal machine of the side defense area, cannot intrude into the station, and cannot have the risk of side impact with the target entrance, so that the safety level of side impact protection is improved.
Wherein the target approach may include one or more of: a pickup approach or a departure approach.
In another possible design, the interval side protection condition may include: the interval direction of the side guard interval is the non-car-receiving direction.
Wherein, the non-receiving direction comprises a departure direction or no direction.
That is, the side guard section opening has no direction or is a direction away from the target approach, that is, there is no possibility of side impact with the target approach, and at this time, the side guard section inspection condition is not used as an inspection condition for locking the target approach and opening a signal, thereby reducing the influence on the station operation efficiency.
In a second aspect, a train side impact protection system is provided. The system comprises a computer interlock, a side protection annunciator, a side protection track section and a side protection turnout, wherein the computer interlock is used for executing the side impact protection method according to any implementation mode of the first aspect.
In a third aspect, a computer-readable storage medium is provided. The medium stores a computer program which, when executed by a processor, enables the side impact protection method according to any implementation manner of the first aspect.
In a fourth aspect, a computer program product is provided. The program product comprises a computer program which, when executed by a processor, enables the side-impact protection method according to any one of the implementations of the first aspect.
Based on the technical scheme provided by the invention, the section side prevention condition related to the target approach side prevention can be used as the checking condition of target approach locking and signal opening. The safety level of train operation can be further improved compared to considering only the on-station side impact protection scheme.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention may be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The prior art to which the inventive solution relates is first described in connection with the 2 scenarios shown in fig. 1-2.
Illustratively, fig. 1 is a schematic view of a station inside impact protection scheme in a pickup access scenario. As shown in fig. 1, taking the approach of the incoming traffic signal 1-3 to the stock track 63T as an example, this approach direction may be defined as the upward direction. For this pickup access scenario, the station inner side impact protection conditions may be as shown in table 1.
TABLE 1
Please refer to line 1 of table 1, (3-71 t or ds) 3-3t or d: the target approach side anti-checking condition is that the in-station section 3-71T is idle, or is locked by other shunting approaches or train approaches with the Down (D) direction far away from the own train receiving approach; the in-station section 3-3T is free or locked by other train approaches in the downstream direction away from the own pickup approach.
Please refer to line 2 of table 1, similar to line 1 above, (4-72 t or x us) 4-4t or x u represents: the target approach side anti-checking condition is that the station inner section 4-72T is idle, or is locked by other shunting approaches or train approaches with the upward (Up, U) direction far away from the receiving approach; the intrastation section 4-4T is either idle or locked by other train approaches that are upstream away from the own pickup approach.
Please refer to line 3 of table 1, N102 OR (2-72 t OR x us) 2-4t OR x u represents: when the turnout 102 is positioned, the sections 2-72T and 2-4T in the station are not used as side-protection checking conditions, or when the turnout 102 is reversed, the side-protection checking conditions of the target route are that the sections 2-72T in the station are idle or are locked by other shunting routes or train routes which are far away from the route in the ascending direction; the intrastation sections 2-4T are idle or locked by other train routes upstream away from the present route.
Illustratively, fig. 2 is a schematic diagram of a station-inside-impact protection scheme in a departure approach scenario.
As shown in fig. 2, taking an example of a departure route from the outbound signal 32 to the section corresponding to the signal 3-3, the route direction is defined as a downstream direction. The side impact protection conditions for this departure approach are shown in table 2.
TABLE 2
Referring to line 1 of table 2, (1-71T or ds) 1-3T or d indicates that the target approach side inspection prevention condition is that the in-station section 1-71T is idle, or is locked by other shunting approaches or train approaches away from the own train approach in the downstream direction; the in-station zones 1-3T are either idle or locked by other train approaches downstream away from the approach of the present invention.
Please refer to line 2 of table 2, 115t or u or us represents: the target approach side check prevention condition is that the in-station section 115T is idle, or is locked by another shunting approach or train approach that is away from the own train approach in the ascending direction.
From the side impact protection conditions (see tables 1-2) of the 2 typical job scenarios shown in fig. 1-2 above, it can be seen that: regardless of the side protection condition configuration, the existing side protection implementation mode is mainly focused on side impact protection in each running scene in the station. There is no special consideration for the scenes when other trains run in the relevant section in the operation process in the station.
In order to solve the problems, the embodiment of the invention provides a side impact protection method, which provides a side impact protection scheme in a train operation scene in different operation time intervals of a station on the basis of the existing station side impact protection scheme, and combines the station side impact protection scheme and the interval side impact protection scheme, so that the safety level of train operation is further improved.
Fig. 3 is a schematic flow chart of a side impact protection method according to an embodiment of the present invention. As shown in fig. 3, the method comprises the steps of:
s301, acquiring the section direction related to the protection of the side face of the target route.
S302, determining that the side protection condition of the target route section is met.
S303, locking and unlocking the target route.
Specific implementation of the side impact protection method provided by the embodiment of the invention is described in detail below with reference to examples shown in fig. 4 to 5.
Fig. 4 is a schematic diagram of a section side impact protection scheme in a train-receiving approach scenario according to an embodiment of the present invention. As shown in fig. 4, taking the pickup route of the traffic light 1-3 to the stock road 63T as an example, when the section direction of the downstream positive line section opening of the throat on the same side as the target route is the upstream direction (i.e., the pickup direction), the section side prevention condition can be checked as follows:
the first zone (e.g., zone 3-1T) outside the target approach side interentrance stop annunciator is idle or occupied for a time period greater than or equal to a preset time period (e.g., 60 seconds). In this scenario, when the first section (e.g., section 3-1T) outside the inbound traffic signal 3-3 is occupied, the inbound traffic signal 1-3 is turned off, and when the first section (e.g., section 3-1T) outside the target approach side defense area entrance traffic signal is occupied for a predetermined period of time, the inbound traffic signal 1-3 is automatically reopened. The section port corresponding to the incoming signal machine 3-3 is a target approach side defense section port, and the preset duration is used for judging that the train is stopped and stabilized outside the incoming signal machine 3-3, so that the risk of entering a station is avoided.
On the other hand, when the section direction of the target entrance side guard section corresponding to the entrance signal 3-3 is the pickup direction, it is conceivable to add the section side guard condition check described in the previous section. On the other hand, when the section direction of the target entrance side defense section port corresponding to the entrance signal 3-3 is the departure direction or the no direction, the target entrance side defense section port does not have the risk of side rushing with the target entrance, and at this time, the 3-1T is not used as the section side defense inspection condition of the target entrance.
Fig. 5 is a schematic diagram of a section side impact protection scheme in a departure approach scenario according to an embodiment of the present invention. As shown in fig. 5, taking the departure approach of the outbound traffic signal 32 to the section port corresponding to the traffic signal 3-3 as an example, when the section direction of the ascending positive line section port of the same side throat as the target approach is the ascending direction (i.e., the pickup direction), the added section side prevention condition is checked as follows:
the first section (e.g., 1-1T) outside the target approach side interentrance stop signal is idle or occupied for a time period greater than or equal to a preset time period (e.g., 60 seconds). In this scenario, the outbound annunciator 32 is turned off when the first zone outside the inbound annunciator 1-3 (e.g., 1-1T) is occupied, and the outbound annunciator 32 is automatically reopened after the first zone outside the target approach side defense zone entrance inbound annunciator (e.g., 1-1T) is occupied for a predetermined period of time. The interval corresponding to the incoming signal machine 1-3 is a target approach side defense interval, and the preset duration is used for judging that the train is stopped and stabilized outside the incoming signal machine 1-3, so that the risk of entering a station is avoided.
On the other hand, when the section direction of the section port corresponding to the incoming signal 1-3 is the pickup direction, the section side protection condition check described in the previous section may be added. On the other hand, when the section direction of the section port corresponding to the incoming signal 1-3 is the departure direction or the no direction, the side impact risk with the target approach is not present at the target approach side defense section port, and at this time, the section side defense inspection condition of the target approach is not set at 1-1T.
Fig. 6 is an exemplary train side impact protection system according to an embodiment of the present invention. As shown in fig. 6, the system comprises a computer interlock, a side protection annunciator, a side protection track section, and a side protection switch, wherein the computer interlock is used for executing the side impact protection method according to the embodiment of the method.
Embodiments of the present invention provide a computer-readable storage medium. The medium stores a computer program which, when executed by a processor, enables the side impact protection method as described in the method embodiments above to be implemented.
Embodiments of the present invention provide a computer program product. The program product comprises a computer program which, when executed by a processor, enables the side-impact protection method as described in the method embodiments above to be implemented.
