[0002] In order to meet the growing travel demand, the reliability and efficiency of railway operations are increasingly required. Interlocking routes involve the linkage of multiple devices.

[0044] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0045] Combined with Figure 1As shown, this embodiment provides a method for comparing the consistency of route status of multiple data sources, including: step S1, obtaining an interlocking table and a train control route information table; the interlocking table includes routes and first information corresponding to the routes, and the train control route information table includes routes and second information corresponding to the routes. Step S2, obtaining real-time data of each route in the interlocking table from multiple data sources. Step S3, using a logic analyzer to compare the interlocking table and the train control route information table for consistency. Step S4, if the interlocking table and the train control route information table are consistent, using the logic analyzer to compare the first information corresponding to the route in the interlocking table and the real-time data of the same route for consistency. Step S5, if the first information corresponding to the route in the interlocking table and the real-time data of the same route are inconsistent, the logic analyzer outputs a first analysis result and issues an alarm prompt; and the first analysis result is that the interlocking route status is inconsistent.

[0046] Specifically, in step S1, the interlocking table can be obtained from a computer interlocking (CI) system; and when the computer interlocking system processes a route, a route is added to the interlocking table and the first information corresponding to the added route is recorded. More specifically, the first information corresponding to the route in the interlocking table includes route sequence number, starting signal, starting button, terminal button, route type, track section, switch position, protective switch position, hostile signal, over-limit insulation section, and starting signal open light position; and the route sequence numbers in the interlocking table are continuous.

[0047] The train control route information table can be obtained from the train control center (TCC); and when the train control center receives a route information sent by the computer interlocking system, a route is added to the train control route information table and the second information corresponding to the added route is recorded. More specifically, the second information corresponding to the route in the train control route information table includes route sequence number, interlocking route sequence number (i.e., route sequence number in the interlocking table), track information, the name of the starting signal machine, the name of the terminal signal machine, the location of the switch included in the route, and the track section included in the route; and the route sequence numbers in the train control route information table are continuous.

[0048] It can be understood that the interlocking table is a relationship table of the mutual interlocking of station signal equipment (signals, switches, track circuits, etc.), and the train control route information table is data for directly commanding and controlling train operation; therefore, the interlocking table and the train control route information table are both the main means to ensure driving safety and improve driving efficiency.

[0049] Specifically, in step S3, if the number of routes in the train control route information table is the same as the number of routes in the interlocking table, and the route sequence number, the name of the starting signal, the route including the switch position, and the route including the track section corresponding to the route in the train control route information table are the same as the route sequence number, the starting signal, the switch position, and the track section corresponding to the same route in the interlocking table, the logic analyzer determines that the interlocking table and the train control route information table are consistent; otherwise, the logic analyzer determines that the interlocking table and the train control route information table are inconsistent. Further, if the interlocking table and the train control route information table are inconsistent, the logic analyzer outputs a second analysis result and issues an alarm prompt, and the second analysis result is that the train control interlocking route status is inconsistent; in this case, the train cannot run to ensure the safety of the train.

[0050] More specifically, the logic analyzer determines that the interlocking table and the train control route information table are inconsistent if one of the following situations exists:

[0051] (1) The computer interlocking system processed a route, but did not send the route information to the train control center;

[0052] (2) The computer interlocking system processes one route, but sends other route information to the train control center;

[0053] (3) The computer interlocking system processed a route and sent the route information to the train control center; however, after the status of the route changed, the computer interlocking system did not send the route status change information to the train control center, and the route status change information included the status changes of the signal, track section, and switch corresponding to the route.

[0054] It can be understood that the above situation (1) will cause the number of routes in the train control route information table to be different from the number of routes in the interlocking table, the above situation (2) will cause the route number corresponding to the route in the train control route information table to be different from the route number corresponding to the same route in the interlocking table, and the above situation (3) will cause the route corresponding to the route in the train control route information table to include the switch position and the route to include the track section to be different from the switch position and track section corresponding to the same route in the interlocking table; therefore, when the above situation (1), (2) or (3) occurs, the logic analyzer determines that the interlocking table and the train control route information table are inconsistent.

[0055] Specifically, in step S2, the railway signal centralized monitoring system (CSM) can be used to obtain real-time data of each route in the interlocking table from multiple data sources. Optionally, the multiple data sources include the computer interlocking system, the train control center, the CTC (Centralized Traffic Control, centralized dispatching system) system and the ZPW2000 non-insulated track circuit system. Optionally, the real-time data of the route includes the actual state of the track section, the actual position of the turnout, the actual state of the over-limit insulation adjacent section, the actual position of the protective turnout and the actual state of the hostile signal; and these data can be obtained from the computer interlocking system data source. Optionally, the signal centralized monitoring system is used to obtain the real-time data of the route in the interlocking table once per second, but the present invention is not limited to this.

[0056] Specifically, in step S4, the actual state of the track section corresponding to any route in the interlocking table is occupied, or the switch position is inconsistent with the actual position of the switch, or the actual state of the over-limit insulation adjacent section is locked or occupied, or the protection switch position is inconsistent with the actual position of the protection switch, or the actual state of the hostile signal is open, the logic analyzer determines that the first information corresponding to the route in the interlocking table is inconsistent with the real-time data of the same route, and the logic analyzer outputs the first analysis result (i.e., the interlocking route status is inconsistent) and issues an alarm prompt.

[0057] Specifically, the route type corresponding to the route in the interlocking table is a receiving route and there is a ramp at the starting signal, and the logic analyzer performs a consistency comparison between the first information corresponding to the continued route in the interlocking table and the real-time data of the continued route; and the actual state of the track section corresponding to the continued route in the interlocking table is occupied, or the switch position is inconsistent with the actual position of the switch, or the protection switch position is inconsistent with the actual position of the protection switch, or the actual state of the hostile signal is open, and the logic analyzer determines that the first information corresponding to the continued route in the interlocking table and the real-time data of the continued route are inconsistent, and the logic analyzer outputs the first analysis result (i.e., the interlocking route status is inconsistent) and issues an alarm prompt.

[0058] Specifically, when the route type corresponding to the route in the interlocking table is a departure route, the real-time data of the route also includes the actual status of the departure route's inspection light. When the departure route is sent to a conventional speed section, the real-time data of the route also includes the actual status of the departure indicator light; when the departure route is sent to a section of the train control center, the real-time data of the route also includes the section direction data of the train control center; when the departure route is sent to a section, the real-time data of the route also includes the actual status of the first interlocking section of the section. More specifically, the actual status of the departure indicator light and the actual status of the inspection light can be obtained from the computer interlocking system; the section direction data and the actual status of the first interlocking section of the section can be obtained from the train control center.

[0059] Furthermore, the method for comparing the consistency of route status of multiple data sources also includes: the actual state of the inspection light of the departure route is a green light or a white light, or the departure route is sent to a conventional speed section and the actual state of the departure indicator light is off, or the departure route is sent to a train control center section and the section direction data of the train control center is not departure, or the departure route is sent to a section and the actual state of the first interlocking section of the section is occupied or lost branch, the logic analyzer outputs the first analysis result (i.e., the interlocking route status is inconsistent) and issues an alarm prompt.

[0060] It can be seen from the above that if one of the following situations occurs, the logic analyzer outputs the first analysis result (i.e., the interlocking route status is inconsistent) and issues an alarm prompt:

[0061] (4) Any section covered by the route in the interlocking table is occupied;

[0062] (5) The position of any turnout in the interlocking table is incorrect;

[0063] (6) The adjacent section of the over-limit insulation in the interlocking table is locked or occupied;

[0064] (7) The hostile route in the interlock table is established (i.e., the hostile signal is open);

[0065] (8) The position of the protective switch in the interlocking table is incorrect;

[0066] (9) The check light (if any) on the departure route in the interlocking table is green or white;

[0067] (10) In the interlocking table, when the train is heading for a normal speed section, the departure indicator light goes off;

[0068] (11) In the interlocking table, for the section where the departure route is sent to the train control center, the section direction data of the train control center is not departure;

[0069] (12) In the interlocking table, the train is sent to the section where the first block section of the section is occupied or loses its branch;

[0070] (13) There is a ramp on the receiving route and the starting signal in the interlocking table, and the continued route section in the interlocking table is occupied, the switch position, the protective switch position is incorrect, or the hostile signal is open.

[0071] It is understandable that if the above situations (4) to (13) occur, the train cannot run to ensure the safety of the train. If the above situations (4) to (13) do not occur, the logic analyzer outputs the third analysis result, and the third analysis result is that the interlocking route state is consistent. Further, the logic analyzer outputs the third analysis result, then the train can run.

[0072] Specifically, the step S5 includes: the logic analyzer outputs the first analysis result and pushes the first analysis result into a queue; when the first analysis result in the queue reaches a preset tolerance time, the logic analyzer issues an alarm. Optionally, the preset tolerance time is 10 seconds to 20 seconds; preferably, the preset tolerance time is 15 seconds, but the present invention is not limited thereto.

[0073] In this embodiment, the logic analyzer performs a consistency comparison between the first information corresponding to the route in the interlocking table and the real-time data of the same route once per second, and the logic analyzer outputs an analysis result once per second and can cache all analysis results output within a period of time (e.g., 15 seconds), that is, maintains a result queue for a period of time (e.g., 15 seconds); if the analysis result is consistent (i.e., the interlocking route status is consistent), the previous cached result is cleared and the queue is reset; if the analysis result is inconsistent (i.e., the interlocking route status is inconsistent), the analysis result is pushed into the queue for recording. If the inconsistent results in the queue reach 15 seconds, that is, the analysis results output once per second within 15 seconds are inconsistent, that is, the analysis results output once per second are inconsistent for 15 consecutive times, an alarm prompt is issued.

[0074] In addition, in this embodiment, the logic analyzer is set in each signal, that is, the signal is used as a carrier to establish the logic analyzer; and the logic analyzer is loaded for the starting signal of each route in the interlocking table, that is, the logic analyzer set in the starting signal corresponding to each route in the interlocking table is started and operated, and the other logic analyzers are not started. If the signal is turned off, the logic analyzer eliminates the alarm that has occurred and resets the analysis process, and re-outputs the analysis result.

[0075] Based on the same inventive concept, this embodiment also provides a route status consistency comparison system for multiple data sources, including: a route table acquisition module, a real-time data acquisition module and a logic analyzer.

[0076] The route table acquisition module is connected to the computer interlocking system and the train control center, and is used to obtain the interlocking table from the computer interlocking system and the train control route information table from the train control center; the interlocking table includes the route and the first information corresponding to the route, and the train control route information table includes the route and the second information corresponding to the route.

[0077] The real-time data acquisition module is connected to the route table acquisition module and the signal centralized monitoring system; the real-time data acquisition module uses the signal centralized monitoring system to acquire the real-time data of each route in the interlocking table from multiple data sources.

[0078] The logic analyzer is connected to the route table acquisition module and the real-time data acquisition module, and is used to compare the interlocking table and the train control route information table for consistency; the logic analyzer is also used to compare the first information corresponding to the route in the interlocking table and the real-time data of the same route when the interlocking table and the train control route information table are consistent; the logic analyzer is also used to output a first analysis result and issue an alarm prompt when the first information corresponding to the route in the interlocking table and the real-time data of the same route are inconsistent; and the first analysis result is that the interlocking route status is inconsistent.

[0079] In addition, the logic analyzer is also used to output a second analysis result and issue an alarm when the interlocking table and the train control route information table are inconsistent, and the second analysis result is that the train control interlocking route status is inconsistent. The logic analyzer is also used to output a third analysis result when the above situations (4) to (13) do not occur, and the third analysis result is that the interlocking route status is consistent.

[0080] On the other hand, this embodiment also provides an electronic device, including a processor and a memory; a computer program is stored in the memory, and when the computer program is executed by the processor, the route status consistency comparison method of multiple data sources as described above is implemented.

[0081] On the other hand, the present embodiment further provides a readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the method for comparing route status consistency of multiple data sources as described above is implemented.
