Description
Technical Field
The invention relates to the technical field of rail transit, in particular to a method and a system for cross-station route arrangement of a station in a distributed and autonomous dispatching centralized manner.
Background
Railway system stations sometimes encounter more complex application scenarios, for example, a very complex station is divided into a plurality of stations, the station is integrally controlled by a set of interlocking system (as shown in fig. 1), but at the transportation level, each station is independent, and each station can be treated as an independent station by a dispatching desk and issues a related train operation plan. For such a scenario, a distributed autonomic dispatching centralized system (hereinafter abbreviated as CTC) generally has an application structure that only one set of interface software is set for interlocking with each field, then each field is treated according to an independent station, each station is provided with a set of station equipment, and each station only has an operation right of the station.
This configuration can satisfy most functional requirements, but if the station interlocks can directly align long paths from one field to another, for a CTC system, it is equivalent to a one-time routing across stations between different stations. At this time, the entry needs to be arranged, part of buttons are controlled by one station, the other buttons are controlled by other stations, various conditions need to be checked in combination with station yard display before the arrangement, if one station of the CTC system is arranged in a way at one time, the station has control right to the other station, the principle of only controlling the station is violated, and potential safety hazard is brought, so the function is not realized in the current application.
In current applications, the interlocks may be arranged in a single pass for the particular cross-site long route described above. The long route can be barely discharged by enabling one station to have the control right of the other station, firstly pressing a starting end button required by the route from the station at the starting end of the route and then immediately pressing a terminal button on the interface of the other station to be controlled and then discharging, but the realization method has a plurality of problems: 1) one station is required to have the control right of the other station, which is not in accordance with the basic principle that each station can only control the station, and has potential safety hazard; 2) after the initial end button is issued, the terminal button needs to be pressed and issued by switching to another station interface, the operation is complicated, the interlocking is overtime slightly slow, and the routing cannot be executed; 3) the method only sends the buttons required by the routing to the interlock, does not carry out any condition check, and has certain potential safety hazard; 4) if the station is to be crossed, the station may not communicate with another station, which may affect the normal operation of another station.

For the convenience of understanding, the following further introduces technical details of the above-mentioned solutions of the embodiments of the present invention.
One, cross-station route data composition
For each station related to cross-station routing, a CTC vehicle transaction terminal and a CTC autonomous machine of the station should acquire identical cross-station route data so as to ensure the uniqueness of routing information when the routing information is transmitted in each software; in addition, the completeness of data should be ensured so as to provide enough information for subsequent software judgment logic.
In the embodiment of the present invention, the data content of the cross-site route data includes: a unique ID number for cross-station route entry; the method comprises the steps that a station code of a first sub-route of the cross-station route is located, a unique ID number of a route list of a station where the first sub-route is located, a first sub-route extra check condition, a route arranging button needing to be issued by the station where the first sub-route is located when the cross-station route is arranged, a station code of a nth sub-route of the cross-station route, a unique ID number of a route list of a station where the nth sub-route is located, an nth sub-route extra check condition and a route arranging button needing to be issued by the station where the nth sub-route is located when the cross-station route is arranged; and n is the number of stations involved in the cross-station route.

In the embodiment of the invention, the format of the cross-site route data can be compatible with various complex application scenes, and the invention has flexible expandability. When each software is started, the local file can be read to initialize the data, so that the same and complete cross-station route information list is obtained, and a foundation is provided for interaction among the software. How this information is used will be explained in detail in the following working principle.

Table 1 cross-site route data example
And II, designing the logic of the CTC vehicle service terminal of the requester.
As shown in fig. 3, the CTC car service terminal of the requester is used as a human-computer interaction interface, reads a local route file when starting, initializes data, and after obtaining a basic route list and a cross-station route list of a station where the terminal is located, can determine whether the station has a cross-station routing function according to the list content: if the station does not have the cross-station route entry list, the station does not have the cross-station route entry and route arrangement function; if the station contains the cross-station route list but the sub-route code of any route is equal to the station code, the cross-station route ranking function is not started; if the cross-station route list is contained and the station code of the station in the first sub-route (sub-route 1) exists, the station has the function of requesting cross-station routing for the corresponding cross-station route.
For the matched routing function, a requested CTC vehicle service terminal part is described in detail and serves as a requesting CTC vehicle service terminal, a cross-station routing request is generated and sent to the requesting CTC autonomous machine; the specific process is as follows: and opening a cross-station routing function interface, selecting one to be arranged from the popped cross-station routes which can be applied for arrangement, and then clicking a request to issue the cross-station routing request to the local station autonomous machine, namely the CTC autonomous machine of the requester.
After the cross-station route arrangement request is issued, the requesting CTC vehicle service terminal can prompt an operator according to feedback information of the requesting CTC autonomous machine, the specific expression form is a pop-up message window, and the feedback information is displayed, such as 'manual rejection of the opposite station', 'no response when the opposite station is overtime', 'successful arrangement of cross-station route XXX (cross-station route name)' and the like.
For the requesting CTC vehicle service terminal, once receiving the feedback of the requesting CTC autonomous machine, the operator can consider that the routing operation is finished, and can perform other operations according to the requirement, or try to apply for routing again after receiving the feedback of the failed routing.
And thirdly, designing the logic of the CTC autonomous machine of the requester.
As shown in fig. 4, the workflow of the CTC autonomous machine of the requester mainly includes:
1. and the CTC autonomous machine of the requester reads the local route file and initializes the data when starting.
2. When receiving a cross-station route routing request, firstly, carrying out validity check: if the requested cross-station route ID is not found in the local cross-station route list, or the cross-station route ID is found, but the station code of the first sub-route in the corresponding cross-station route is not the station code of the station of the CTC autonomous machine of the requesting party, discarding the cross-station route routing request; if the cross-station route ID is found and the station code of the first sub-route is the station code of the requesting CTC autonomous machine, then the effective cross-station route request information is judged to be received.
3. And (5) checking the routing condition.
1) And if the routing condition is not met, not performing subsequent logic, and feeding back a message which fails the routing condition check to the CTC vehicle service terminal of the requester.
Specifically, the method comprises the following steps: 1) if the routing condition is not met, the request CTC vehicle service terminal is fed back with the result that the station routing condition is not met and the XXX (item for not passing the check) condition is not met. The advantage of this is that the resources of the autonomous machine are saved, and if the conditions of the station are not satisfied, the station does not need to communicate with other stations for application. The checking of the routing condition at this time mainly comprises checking of basic routing conditions and special routing conditions. The basic routing conditions comprise interlocking basic routing conditions such as free access, no sealing of turnouts and the like, and CTC routing conditions such as no sealing, power failure, poor shunting and the like. The special arrangement condition, which is a special condition configured in the route, that is, the aforementioned additional check condition, as in the example of table 1, the sub-route 1 is arranged to request the object with type 0x06 serial number 3, which must be in the color code 0 state (type 0x06 means "pick-up direction lamp" object, color code 0 state means "off", and the whole means that the pick-up direction lamp with serial number 3 must be in the off state), the object with type 0x0f serial number 9 must be in the color code 4 state (type 0x0f means "warning lamp" object, color code 4 state means "green", and the whole means that the warning lamp with serial number 9 must be in the green state), and both conditions are in an and relation and need to be satisfied simultaneously. These special conditions are added, mainly because these are not checked in the basic check conditions, and sometimes the interlocks have special jamming. The conditions are configured, if the conditions are not checked by the autonomous machine, the conditions can be directly fed back to an operator, so that the conditions are a prompt, the situation that the interlocking is given by a command is avoided, and the time is wasted because the conditions are not met in the end of the interlocking.
2) And if the routing condition is met, checking the routing condition, and establishing a cross-station routing command in the request-side CTC autonomous machine, monitoring the state of the cross-station routing command, and sending feedback information to all stations related to the cross-station route according to the monitoring result in real time.
4. For the case 2), the requesting CTC autonomous machine sends matching routing request information to CTC devices in other sub-route stations included in the cross-station route, where the number of the other sub-route stations is 1 or more, and the CTC devices in the other sub-route stations are all the requesting CTC devices. If the requesting CTC autonomous machine does not receive the feedback message of the requested CTC equipment or receives all the feedback messages or receives the refusing message within the specified time, sending a message of flow end to all the requested CTC equipment, and deleting the cross-station routing command and then not monitoring; and if the matching approval messages fed back by all the requested CTC equipment are received, the routing condition is checked again.
The following are exemplary:
1) if the feedback message of the requested CTC device is not received or all the feedback messages are not received within a predetermined time (for example, 15s), the message of ending the transmission process is: and (4) the XXX station (station name without feedback) is matched with the routing request and has no response when the time is out, and the process of cross-station routing XXX (cross-station route name) is finished.
2) If the rejection message is received, the sent message of ending the flow is as follows: the XXX station (the station name of the feedback rejection) rejects due to XXX (a specific reason in the feedback information), and the cross-station routing XXX flow ends.
5. And after receiving the matching agreement messages fed back by all the CTC equipment of the requested party, checking the routing condition again. If the routing condition is not met, sending a message of flow end to all requested CTC equipment, and deleting the cross-station routing command to be monitored no longer subsequently; if the routing condition is met, the routing condition is checked, a button required to be pressed by a station where a requesting party is located in a cross-station route is issued to the interlocking interface, and then a routing command issuing request is sent to CTC equipment of the requested party according to a cross-station route configuration sequence. If the feedback message of the CTC equipment of the requested party is not received within the specified time (for example, 5s), or the received feedback message is a message that the station where the requested party is located does not meet the routing condition, sending a message of ending the process to the CTC equipment of the requested party, and deleting the cross-station routing command and then not monitoring; if the feedback is the successful issuing message, whether the current cross-station routing has a subsequent sub-routing is judged, if yes, a routing command issuing request is sent to the requested CTC equipment corresponding to the subsequent sub-routing (the sequence is: second sub-routing → third sub-routing) until the successful issuing message fed back by all the requested CTC equipment is received.
The following are exemplary:
1) in this phase, if the routing condition of the station where the CTC device of the requesting party is located is not satisfied, the message of the end of the flow is sent as: and (3) the XXX station routing condition is not met, the XXX (item for not passing inspection) condition is not met, the cross-station routing XXX process is ended, and the message is sent to the requested CTC autonomous machine by the requesting CTC autonomous machine so as to be displayed on the requested CTC vehicle service terminal.
2) After sending the routing command issuing request, if there is no feedback after timeout (set to 5S in the example), the sent message of flow ending is: and XXX station, routing command issuing request is overtime, and the cross-station routing XXX process is finished.
3) After sending a routing command issuing request, if the received feedback message is a message that the station where the requested party is located does not meet the routing condition, the sent message of ending the flow is: the XXX station routing condition is not satisfied, the XXX (item for which inspection fails) condition is not satisfied, and the cross-station routing XXX flow ends.
6. After all the commands of the cooperating stations (namely, stations corresponding to non-first sub-routes) are issued, the requesting CTC autonomous machine represents information through a station yard, monitors whether routes are successfully arranged, if the routes are not arranged within overtime (for example, exceeding 45s), feeds back an interlocking overtime message to all requested CTC equipment, deletes a cross-station route arranging command, and sends a flow ending message to all the requested CTC equipment; and if the route arrangement is successful, feeding back a message of successful cross-station route arrangement to all the requested CTC equipment, deleting the cross-station route arrangement command, and sending a message of flow end to all the requested CTC equipment.
The following are exemplary:
1) the interlock timeout message may be: and the command of arranging the route of the XXX of the cross-station route is successfully issued, but the interlocking timeout does not react.
2) The message that the cross-station route arrangement is successful may be: the ranking of the cross-station routes XXX was successful.
In the above working process, whenever the requesting CTC autonomous machine deletes the local cross-site route arrangement command, it should simultaneously send the information of ending the process to the other related CTC autonomous machines (i.e. the requested CTC autonomous machines), and timely inform the opposite side that the local cross-site route arrangement has succeeded or failed, without monitoring the command state.
And fourthly, designing the logic of the CTC autonomous machine of the requested party.
As shown in fig. 5, the workflow of the CTC autonomous system of the requested party mainly includes:
1. the requested CTC autonomous machine reads the local access file and initializes the data when starting.
2. When receiving the matching routing request information, carrying out validity check: if the cross-station route ID matched with the routing request information is not found in the local route list, or the station codes of all sub-routes in the cross-station route are not the station codes of the station where the CTC autonomous machine of the requested party is located, feeding back a refusal message; if the cross-station route ID route is found and the station code of the station where the non-first sub-route is located is the station code of the station where the CTC autonomous machine of the requested party is located, judging that effective matching routing request information is received.
3. And (5) checking the routing condition.
1) And if the routing condition is not met, feeding back a rejection message to the CTC autonomous machine of the requesting party, and not performing subsequent logic.
Illustratively, the rejection message may be: the XXX station routing condition is not satisfied, and the XXX (item for which inspection does not pass) condition is not satisfied.
2) If the routing condition is met, the requested CTC autonomous machine sends a message of whether routing is matched to the requested CTC vehicle service terminal through the routing condition check; if receiving the agreement message, feeding back the agreement coordination message to the CTC autonomous machine of the requesting party; and if the rejection message is received, feeding back the rejection message to the CTC autonomous machine of the requesting party (rejection reason 'artificial rejection').
For example, the message of whether to coordinate the routing may be: XXX stations (station names requesting matching routes) request ranking of XXX, across inbound routes, if matched?
4. After the CTC autonomous machine of the requested party feeds back the matching agreement message to the CTC autonomous machine of the requesting party, a command is created, and whether the CTC autonomous machine of the requesting party issues a routing command issuing request in time or not is monitored; and then, if a message of flow ending is received, the cross-station routing flow is ended, monitoring is not needed, and the local corresponding command is deleted. If the routing command issuing request is not received within the specified time (for example, 5s), deleting the corresponding command, and then not monitoring any more, and even if the routing command issuing request is received later, not responding; if the request for issuing the routing command is received within the specified time, the routing condition check is carried out again. If the routing condition is not met, feeding back a message which does not meet the routing condition to a request CTC; if the routing condition is met, the button which is required to be pressed by the station where the requested party is located in the cross-station access is sent to the interlocking interface through the routing condition check, and then a successful sending message is fed back to the CTC equipment of the requesting party; and judging the route arrangement condition of the cross-station route, and uniformly handing the judgment to the requesting independent machine, wherein only the requesting CTC independent machine knows the request and the issuing progress of each sub-route of the cross-station route. Thereafter, if the flow ending information sent by the CTC autonomous machine of the requesting party is not received within a predetermined time (e.g., 45s), the local corresponding command is deleted, and then monitoring is not performed.
In the embodiment of the present invention, the specific values related to each of the specified times are given as examples, but the specific values may be appropriately adjusted according to actual situations or experience, and the present invention is not limited thereto.
And fifthly, designing the logic of the CTC vehicle service terminal of the requested party.
As shown in fig. 6, the requested CTC car transaction terminal also needs to initialize data at startup.
After receiving the inquiry sent by the local station autonomous machine to determine whether the routing information is matched, checking the validity of the information, checking the logic of the information and the local station autonomous machine, and if the logic of the information is not legal, directly feeding back a rejection window-popup-free prompt; if the station is legal, the popup prompts the XXX station (the station name requesting to match with the route) to request to arrange the XXX of the cross-station route, if the station is matched? .
In this case, the operator can decide whether to cooperate with the station according to the specific situation of the station. If the click is rejected, feeding back rejection to the local station autonomous machine; if yes, giving back an agreement to the local autonomous machine; if the timeout (set to 15S in the example) is not selected, the window is closed, the requester autonomously determines the timeout at the same time, and feeds back "XXX station (station name without feedback) to each station to cooperate with routing request timeout without response, and the cross-station routing XXX flow ends".
And then the car service terminal can prompt the arrangement progress of the cross-station route according to some feedback information of the autonomous machine, for example, the XXX station route arrangement condition is not met, the XXX (item which is not checked to pass) condition is not met, the cross-station route arrangement XXX process is finished, the cross-station route XXX route arrangement command is successfully issued, but the interlocking is overtime and does not react, the cross-station route XXX arrangement is successful, and the like.

In the embodiment of the invention, interlocking interface software is designed for interlocking and the conversion of CTC system information, in the embodiment of the invention, a plurality of stations of CTC interact with interlocking through an interlocking interface, and the interlocking method specifically comprises the following steps: when the interface software receives the control commands of the relevant stations, converting the commands into interlocking corresponding command numbers one by one according to the command big queuing information and issuing the command numbers; after receiving the presentation information sent by the interlock, each presentation information is converted into CTC internal number display according to the presentation large queuing information, the original integral presentation is distinguished by taking the station as a unit according to the station to which the number belongs, and the presentation information is sent to each CTC device by taking the station as a unit.
And seventhly, a computer interlocking simulation system.
The computer interlocking simulation system is mainly used for simulating station interlocking, executing corresponding operation according to a control command sent by interlocking interface software, wherein the software has own check conditions when executing the operation, and if the conditions are not met, the corresponding command cannot be executed, and no feedback is given to the interlocking interface; in addition, the interlocking simulation software can also send total station representation information at fixed time or send change representation information to the interlocking interface software when the change occurs. For the present example, after buttons required for arranging the cross-station route are sequentially received, corresponding operations are executed, and then changed presentation information is sent to the interface software after the cross-station route arrangement is completed.
The scheme of the invention mainly obtains the following beneficial effects:
1) compared with the existing operation mode, the method firstly switches to the non-stop control mode and then arranges the buttons on the interlock points, the cross-station route arranging method provided by the invention keeps the convenience characteristics of the CTC system, the operation is simple and visual, an operator only needs to apply, approve or reject, and the other complex logic judgments are all finished by a background autonomous machine; the realization of the whole scheme not only ensures the safety of the function, but also keeps the simplicity of the system operation, and brings better user experience for operators.
2) And perfect condition check is provided in the routing process, and the failure reason can be fed back to an operator when the failure occurs, so that the follow-up problem checking is facilitated.
3) Each station independently controls the station, and when the cross-station route needs to be arranged, the system automatically applies for other related stations.
4) When the stations needing to be matched are inconvenient to be matched and arranged, the station can be selected to reject the channel, and the normal operation of the station is preferentially ensured.
5) After other stations agree to match, operators at each station can know the arrangement condition of the access roads in time.
In a word, the method does not violate the principle that each station of the dispatching concentration system can only control the station, does not influence the existing routing logic of the system, ensures the completeness of routing inspection and the safety of the system through a perfect communication flow, and can well solve the problem that cross-station routing cannot be realized in the current application.
