Description

Technical Field

[0001] This invention relates to the field of signal display in railway signaling systems, and specifically to a method for comparing the consistency between section signal display and section code issuance. Background Technology

[0002] Currently, railway signaling systems are constantly being improved and their functions optimized, and the safety and reliability of each subsystem are getting higher and higher. However, there are still hidden dangers in the interfaces between subsystems, making it particularly necessary to strengthen the consistency of information between key signaling equipment.

[0003] For comparing the consistency of safety information between sections, traditional methods mainly establish analysis models for all sections, section signals, and station entry signals. This involves a large number of analysis objects and a complex analysis process, resulting in low analysis efficiency and low accuracy of analysis results. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of low analysis efficiency and low accuracy of analysis results caused by the large number of analysis objects and the complexity of the analysis process in current interval security consistency comparison methods.

[0005] To achieve the above objectives, this invention proposes a method for comparing the consistency between interval signal display and segment code transmission, comprising the following steps:

[0006] S1. The logic for comparing the consistency of interval signal display and segment code issuance is divided into multiple sub-logics according to the device type;

[0007] S2. Create engineering data configuration files for each signal device;

[0008] S3. Based on the engineering data configuration files of each signal device, the monitoring system generates corresponding logical analysis entities for each signal device and initializes them.

[0009] S4. The monitoring system distributes the collected information from each signal device to each logical analysis entity.

[0010] S5. Each logical analysis entity analyzes the received device data based on the associated sub-logic. When the analysis finds inconsistencies in the status, an alarm is issued.

[0011] Among them, the multiple sub-logic include: station entry signal analysis logic, section analysis logic, and section signal analysis logic.

[0012] The entry signal analysis logic is as follows: taking an entry signal as the object, analyze the signal consistency between the entry signal and the adjacent section and section signals behind it;

[0013] When the entrance signal is lit, compare the lighting status of the entrance signal with the lighting status of the signals in the following section and the consistency of the section code issuance; when the entrance signal is off, compare the status of the entrance signal with the occupancy status of the following section.

[0014] The interval segment analysis logic is as follows: taking an interval segment as the object, analyze the consistency between the code issuance and occupancy status of the interval segment and the code issuance and signal light status of the adjacent interval segment;

[0015] When a section is occupied, analyze whether the code issued by the subsequent section corresponds to the occupancy status and whether the section signal shows that it is occupied; when a section is not occupied, analyze the consistency between the code issued by this section and the code issued by the subsequent section.

[0016] The section signal analysis logic is as follows: taking a section signal as the object, analyze the consistency of the lighting status of the section signal with the adjacent section signal behind it;

[0017] When the signal in section occupancy is displayed, analyze whether the signal in the adjacent section behind it is about to be occupied; when the signal in section occupancy is displayed, analyze whether the signal in the adjacent section behind it is available for occupancy.

[0018] Step S2 further includes the following steps:

[0019] S21. Generate engineering data configuration objects for each signal device and load configuration information for them;

[0020] S22. Establish connection relationships between the generated engineering data configuration objects.

[0021] The configuration information includes the name, type, and data collection information of each signaling device; the signaling devices include entry signals, section signals, and section segments.

[0022] The information collected for the station entry signal and the section signal includes light position information, while the information collected for the section includes the section occupancy status and the section code issuance information.

[0023] The connection relationship includes the front-to-back relationship of each signaling device relative to the train's direction of travel, information on the upper connection device, and information on the lower connection device.

[0024] Step S3 further includes the following steps:

[0025] S31. The monitoring system associates the engineering data configuration objects of each signal equipment with the corresponding sub-logic and generates the corresponding logic analysis entities, including: the logic analysis entity of the station entrance signal, the logic analysis entity of the section, and the logic analysis entity of the section signal.

[0026] S32, Load the device acquisition information required for consistency comparison for each logical analysis entity.

[0027] Specifically, step S32 is as follows:

[0028] Load the entry signal light position information, section signal light position information, section occupancy status, and section code issuance information into the logic analysis entity of the entry signal;

[0029] Load the interval segment occupancy status, interval segment code issuance information, interval signal light position information, and subsequent interval segment code issuance information for the interval segment logic analysis entity;

[0030] Load the signal light position information of the section signal and the signal light position information of the adjacent section signal into the logic analysis entity of the section signal.

[0031] Step S4 further includes the following steps:

[0032] S41. The monitoring system acquires the signal equipment collection information required for consistency comparison sent from the interfaces of each train control subsystem in real time.

[0033] S42. The monitoring system converts the signal equipment collection information required for the consistency comparison into a unified monitoring data format;

[0034] S43. The monitoring system performs time-series analysis on the device acquisition information required for the obtained consistency comparison, and aligns the device acquisition information at the same time.

[0035] S44. The monitoring system sends aligned and formatted data to each logical analysis entity;

[0036] Steps S42 and S43 are not sequential.

[0037] Specifically, the device acquisition information within the selected time and the first time threshold before and after it is regarded as the device acquisition information at the same time. The first time threshold is set according to the actual situation.

[0038] Compared with the prior art, the present invention takes each signal device as the main object of analysis and breaks down the complex line information consistency comparison logic into multiple simpler sub-logics, thereby ensuring the integrity of the logic while (1) reducing the complexity of the analysis logic; (2) improving the accuracy of the analysis results, which is conducive to the timely detection and handling of signal inconsistency faults and ensuring driving safety.

[0041] The following will be combined with the embodiments of the present invention. Figure 1 and Figure 2 The technical solutions, structural features, objectives and effects achieved in the embodiments of the present invention will be described in detail.

[0042] It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions. They are only used to facilitate and clarify the purpose of illustrating the embodiments of the present invention, and are not intended to limit the implementation conditions of the present invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in the proportional relationship, or adjustments to the size should still fall within the scope of the technical content disclosed in the present invention, provided that they do not affect the effects and objectives that the present invention can produce.

[0043] It should be noted that, in this invention, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only the expressly listed elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0044] This embodiment discloses a method for comparing the consistency of interval signal display and segment code transmission. This method employs a divide-and-conquer approach, breaking down complex logic according to signal device type. Therefore, it only requires comparing the consistency between each signal device and its adjacent devices. Figure 1 As shown, the consistency comparison method in this embodiment specifically includes the following steps:

[0045] S1. The logic for comparing the consistency of the interval signal display and the segment code transmission is divided into multiple sub-logic based on the device type, such as... Figure 2 As shown, the sub-logos are: station entry signal analysis logic, section analysis logic, and section signal analysis logic. When a train is traveling on the track, the states of adjacent station entry signals, section signal codes, and section signals when facing a train approaching and departing should be consistent within a certain time error. Based on this, the entire track is broken down, and the consistency of the state of each individual signal device with the signal devices before and after it is analyzed. Here, "before and after" refers to the direction along which the train travels.

[0046] The consistency of the state does not mean that all signal devices have the same state, but that the states of each signal device do not conflict within a certain time error. For example, before a train enters the station, the light position of the entry signal indicates that the train is allowed to enter the station, and the section code and the light position of the section signal should both be in the state of allowing the train to enter the station.

[0047] The analysis logic for the entrance signal is as follows: Taking an entrance signal as the object, analyze the signal consistency between the entrance signal and the adjacent section signals behind it; when the entrance signal is lit, compare the lighting status of the entrance signal with the lighting status of the adjacent section signals and the code transmission consistency of the section; the entrance signal lighting includes various light positions, including light positions indicating that the train passes through the station at a specified speed, light positions indicating that the train enters the station and then stops, light positions indicating that the train decelerates before entering the station, and light positions indicating that the train is not allowed to enter the station, etc. When the entrance signal displays the corresponding light position, the light positions displayed by the adjacent section signals and the adjacent... The code issuance for a section should not conflict with the position of the entrance signal. For example, when the entrance signal indicates that the train is passing through the station at the prescribed speed, the position of the subsequent section signal should indicate that the train is allowed to pass through that section signal. At the same time, the code issuance for the subsequent section should also indicate that the train is allowed to pass through that section at the prescribed speed. In this case, the entrance signal's lighting status is considered to be consistent with the lighting status of the subsequent section signal and the section code issuance. When the entrance signal is off, the consistency between the entrance signal's status and the subsequent section's occupancy status is compared. Specifically, when the entrance signal is off, the subsequent section should be in an occupied state.

[0048] The interval segment analysis logic is as follows: Taking an interval segment as the object, analyze the consistency between the code issuance and occupancy status of the interval segment and the code issuance and signal light status of the adjacent interval segment. Specifically, when the interval segment is occupied, analyze whether the status of the adjacent interval segment and the signal light shows that it is occupied. In this embodiment, when the interval segment is occupied, analyze whether the adjacent interval segment issues a red or yellow code to indicate that it is occupied, and whether the signal light of the adjacent interval is red to indicate that it is occupied. When the interval segment is not occupied, analyze the consistency between the code issuance of the interval segment and the code issuance of the adjacent interval segment, that is, analyze whether the code issuance of the interval segment and the code issuance of the adjacent interval segment both indicate that the interval segment is not occupied. In this embodiment, the code issuance of the interval segment and the code issuance of the adjacent interval segment may have multiple possibilities, but none of them can be a red or yellow code.

[0049] The analysis logic for the section signal is as follows: taking a section signal as the object, analyze the consistency of the lighting status of the section signal and the adjacent section signal behind it. For example, when the signal of this section is red to indicate that it is occupied, the adjacent section signal behind it should be yellow to indicate that it will be occupied. When the signal of this section is green to indicate that it is not occupied, the adjacent section signal behind it should indicate that it can be occupied, for example, by lighting a green light.

[0050] S2. Create engineering data configuration files for each signaling device. The engineering data configuration files for each signaling device include equipment information for the station entry signal, the section signal, and the section segment, as well as the connection relationships between each signaling device. This includes the following steps:

[0051] S21. Generate engineering data configuration objects for each signal device and load configuration information for them;

[0052] The configuration information includes the name, type, and acquisition information of each signal device; the signal devices include entry signals, section signals, and section segments; the acquisition information of entry signals and section signals includes light position information, and the acquisition information of section segments includes section segment occupancy status and section segment code issuance information.

[0053] S22. Establish connection relationships between the generated engineering data configuration objects;

[0054] The connection relationship includes the front-to-back relationship of each signaling device relative to the direction of train operation, information on the upper connection device, and information on the lower connection device. The upper and lower positions of the "upper connection device" and "lower connection device" are defined according to actual needs. They can be the same as the front and back positions of the train or the opposite of the front and back positions of the train. For example, when the upper connection device is the signaling device in front of the train, the lower connection device is the signaling device behind the train.

[0055] S3. The monitoring system generates corresponding logical analysis entities for each signal device and initializes them.

[0056] S31. The monitoring system associates the engineering data configuration objects of each signal device with corresponding sub-logic and generates corresponding logic analysis entities. The logic analysis entities include: station entry signal logic analysis entity, section logic analysis entity, and section signal logic analysis entity.

[0057] S32. Load the device acquisition information required for consistency comparison for each logical analysis entity;

[0058] Specifically, the logic analysis entity for the entry signal is loaded with the signal position information of the entry signal, the signal position information of the subsequent section, the occupancy status of the subsequent section, and the code issuance information of the subsequent section; the logic analysis entity for the section is loaded with the occupancy status of the section, the code issuance information of the section, the signal position information of the subsequent section, and the code issuance information of the subsequent section; the logic analysis entity for the section signal is loaded with the signal position information of the section and the signal position information of the adjacent section.

[0059] S4. The monitoring system distributes the collected information from each signal device to each logical analysis entity, specifically including the following steps:

[0060] S41. The monitoring system acquires signal equipment collection information required for consistency comparison sent from the interfaces of interlocking, train control and other subsystems in real time;

[0061] The equipment data required for consistency comparison is obtained through monitoring and data collection from various subsystems in the existing train control system; interfaces for receiving data from these subsystems are set up on the monitoring system; when the monitoring system is working, it obtains the equipment data required for consistency comparison from each train control subsystem in real time.

[0062] S42. The monitoring system converts the signal equipment collection information required for the consistency comparison into a unified monitoring data format so that the subsequent logical analysis entity can perform consistency analysis and judgment on each collection information.

[0063] S43. The monitoring system performs time-series analysis on the equipment collection information required for the consistency comparison and aligns the equipment collection information at the same time. Since there is a time difference in the response of each signal device to the train entering or leaving the station, the equipment collection information within the selected time and the first time threshold before and after it is regarded as the equipment collection information at the same time. The first time threshold is set according to the actual situation. In this embodiment, the first time threshold is 2 seconds. Therefore, the selected time and the 2 seconds before and after it are regarded as the same time.

[0064] It should be noted that the order of steps S42 and S43 above is not important. You can also align the collected information from each device first and then convert the data format.

[0065] S44. The monitoring system sends aligned and formatted data to each logical analysis entity;

[0066] S5. Each logical analysis entity analyzes the received device data based on the associated sub-logic. When the analysis finds inconsistencies in the status, an alarm is issued.

[0067] Although the present invention has been described in detail through the preferred embodiments above, it should be understood that the above description should not be considered as a limitation of the present invention. Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
