Description

Technical Field

[0001] This application relates to the field of train monitoring technology, and in particular to a method, device and system for displaying time difference acquisition. Background Technology

[0002] The Passenger Information System (PIS) is a system that uses a computer system as its core and station or vehicle-mounted display terminals as its medium to provide information to passengers. The vehicle arrival information displayed on the platform broadcast controllers is information shown to passengers while they are waiting on the platform, during their journey, or while waiting to disembark.

[0003] The inventors discovered that in existing solutions, the data source for vehicle arrival information is the Automatic Train Supervision (ATS) system. After the ATS issues the vehicle arrival information, the passenger service system obtains screenshots of the displays from the broadcast controllers at each platform. By analyzing the information on the screenshots, it is confirmed whether the vehicle arrival information is displayed in a timely manner. Alternatively, manual inspections are conducted to check whether the vehicle arrival information from the platform broadcast controllers is timely. The above solutions result in insufficient timeliness in obtaining the display time difference of vehicle arrival information, leading to low real-time performance. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] This application provides a method for displaying time difference acquisition and a system for displaying time difference monitoring, such as... Figure 1 As shown, the time difference monitoring system includes a time difference acquisition device (not shown in the figure), an Automatic Train Supervision (ATS) system, an Integrated Supervisory Control System (ISCS) system, a passenger service system, a message queue (MQ) component, and multiple Passenger Information Playback Devices (PIPDs), such as platform playback device 1, platform playback device 2, ..., platform playback device N. In one embodiment, the vehicle arrival information processing system may also include a log system.

[0035] For ease of explanation, some terms or wording used in this application will be described first:

[0036] Vehicle arrival information: This refers to the information sent by the ATS system to the corresponding platform controllers at the station for display. It is generally information that passengers pay special attention to while waiting on the platform, during their journey, or while waiting to disembark. This vehicle arrival information typically includes the estimated arrival time of the vehicle or other necessary arrival information. The estimated arrival time includes the time it takes for the vehicle to arrive at the next platform or the current platform. This vehicle arrival information is generally provided by the ATS system that manages and monitors vehicle operations.

[0037] ATS transmission time: refers to the time when the Automatic Train Monitoring System sends out vehicle arrival information.

[0038] ATS vehicle code: This is the vehicle code associated with the vehicle's arrival information. Different vehicles are identified by different codes, which will be referred to as vehicle codes below.

[0039] ATS platform code: This is a code used to distinguish different platforms. Different platforms correspond to different ATS platform codes, which will be referred to as platform codes below.

[0040] ISCS reception time: refers to the time it takes for the ISCS system to receive vehicle arrival information.

[0041] ISCS transmission time: refers to the time when the ISCS system sends out vehicle arrival information.

[0042] PIS reception time: refers to the time it takes for the PIS system to receive vehicle arrival information.

[0043] PIS processing time: refers to the time taken for the PIS system to process vehicle arrival information after receiving it.

[0044] PIS transmission time: refers to the time when the PIS system sends out vehicle arrival information.

[0045] MQ forwarding time: refers to the forwarding time of the MQ component to forward vehicle arrival information to the message queue. PIPD consumption time: refers to the time it takes for the station broadcast controller to consume vehicle arrival information from the message queue.

[0046] PIPD display time: This is the time when the platform broadcast controller pushes the acquired vehicle arrival information to the broadcast control interface for display.

[0047] ATS Log: Operation log of the Automatic Train Monitoring System.

[0048] ISCS Log: Operation log of the integrated monitoring system.

[0049] PIS Log: Operation log of the passenger service system.

[0050] MQ Logs: The runtime logs of the message queue component.

[0051] PIPD Log: The operation log of the station broadcast controller.

[0052] Each level of system refers to the various systems that vehicle arrival information passes through from the data source to the platform broadcast controller, including the automatic train monitoring system, integrated monitoring system, passenger service system, message queue component, and platform broadcast controller.

[0053] The platform broadcast controller displays a large amount of information from multiple data sources, including vehicle arrival information, which originates from the Automatic Train Monitoring System (ATS). Figure 1 As shown, after data is transmitted through multiple systems, it is finally sent to the broadcast control interface of the station's broadcast controller for display. Figure 1 The transmission process of vehicle arrival information is as follows:

[0054] S11: The automatic train monitoring system can obtain the estimated arrival time of vehicles (such as the time when each vehicle arrives at the next station platform) and platform codes by calculating axle counting data and train operation data. It then uses this information to organize the raw vehicle arrival information and sends it to the integrated monitoring system.

[0055] S12: The integrated monitoring system, as a data relay station for the signaling and communication systems, quickly transmits the vehicle arrival information sent by the automatic train monitoring system to the passenger service system.

[0056] S13: After receiving the vehicle arrival information transmitted from the integrated monitoring system, the passenger service system parses the platform code and estimated arrival time of the vehicle in the arrival information. Based on the platform code, it queries the information of the broadcast controller installed on the upstream and downstream platforms (including the broadcast controller code). Then, it organizes the broadcast controller code and estimated arrival time of the vehicle into a message message and sends the message message to the message queue component using the topic of the vehicle arrival information.

[0057] S14: The message queue component acts as a message middleware to decouple the passenger service system and the platform broadcast controller. After receiving the vehicle arrival information from the passenger service system, it adds the vehicle arrival information to a message queue for storage until the platform broadcast controller with the specified code consumes this vehicle arrival information.

[0058] S15: When the platform broadcast controller starts, it subscribes to the topic corresponding to the vehicle arrival information in the message queue. Once the message queue has the vehicle arrival information corresponding to the topic, the platform broadcast controller will consume the vehicle arrival information from the message queue and, after parsing it on the platform broadcast controller's local machine, display the final vehicle arrival information on the broadcast control interface.

[0059] S16: The log system is an independent log collection system separate from the automatic train monitoring system, integrated monitoring system, passenger service system, message queue component and platform broadcast controller. It is used to collect logs from the automatic train monitoring system, integrated monitoring system, passenger service system, message queue component and platform broadcast controller, and store them in a unified manner.

[0060] like Figure 2 As shown in this application, each level of the system utilizes logs. The data used to analyze and display the time difference of vehicle arrival information can be linked to the platform controller of the corresponding platform by using the platform code as the connection point. Since a single vehicle arrival message will be sent to multiple platform controllers on the upstream / downstream platforms for display, the log data can be recorded using a time point plus the controller code as the unique record identifier. The log records the ATS transmission time, platform code, ISCS reception time, ISCS transmission time, PIS reception time, PIS processing time, PIS transmission time, MQ forwarding time, PIPD consumption time, and PIPD display time corresponding to the vehicle arrival information.

[0061] The process by which each level of the system uses logs to record relevant information about the transmission of vehicle arrival information is as follows:

[0062] S211: In the ATS log, the main train automatic monitoring system sends the time of collecting vehicle arrival information, i.e., the ATS sending time, as well as the platform code and vehicle code. The above codes are mainly used to establish a correspondence with the corresponding platform broadcast controller.

[0063] S212: The integrated monitoring system is mainly a system that forwards vehicle arrival information. It mainly collects the reception time and transmission time of vehicle arrival information through ISCS logs, that is, ISCS reception time and ISCS transmission time.

[0064] S213: The passenger service system needs to parse the vehicle arrival information message, find the corresponding platform broadcast controller through the platform code, organize the message body, and send it to the platform broadcast controller through the message queue component. Therefore, the PIS log mainly collects the vehicle arrival information reception time, processing time and sending time, i.e. PIS reception time, PIS processing time and PIS sending time.

[0065] S214: The message queue component is only responsible for relaying vehicle arrival information. The MQ log collects the forwarding time of the vehicle arrival information from the message queue component to the message queue, and also includes the receiving time of the vehicle arrival information by the message queue component.

[0066] S215: The platform broadcast controller is used to consume vehicle arrival information from the message queue. After parsing, it updates the platform broadcast controller interface for display. The PIPD log mainly collects the consumption time of vehicle arrival information and the final display time on the platform broadcast controller interface.

[0067] It can be seen that in the later stages of urban rail transit line construction, after the initial deployment of various signaling and communication systems (such as passenger service systems and automatic train monitoring systems), joint debugging is required to meet the operator's acceptance requirements. The vehicle arrival information displayed on the platform broadcast controller involves cross-professional and cross-system data transmission. This application provides a method for obtaining display time difference and such... Figure 1 The vehicle arrival information processing system shown can not only obtain the display time difference of vehicle arrival information in a timely manner, but also effectively avoid the problems of introducing new systems or upgrading existing systems due to system integration and debugging by introducing the collection of logs from various systems.

[0068] The following is combined with Figure 1 and Figure 2 This application provides a detailed description of the display time difference acquisition method and vehicle arrival information processing system provided in the embodiments of this application.

[0069] In one embodiment, such as Figure 2 As shown, this application provides a method for obtaining time difference, which includes the following steps:

[0070] S101: Obtain the operation log from the Automatic Train Monitoring System (ATMS). Based on the operation log, query the sending time of the vehicle arrival information issued by the AMS. The vehicle arrival information includes the platform code.

[0071] The Automatic Train Monitoring System (ATS) calculates axle counting data and train operation data to obtain vehicle arrival information such as estimated arrival time (e.g., the time each vehicle arrives at the next station platform) and platform code. It then parses and organizes this information to obtain the original vehicle arrival information and sends it to the integrated monitoring system. As described above, the ATS log, which is the operation log in the Automatic Train Monitoring System, collects the sending time, platform code, vehicle code, and other information of the aforementioned vehicle arrival information.

[0072] Therefore, in this embodiment of the application, the sending time and platform code of the vehicle arrival information issued by the automatic train monitoring system can be obtained by querying the operation log of the automatic train monitoring system.

[0073] S102: Obtain the operation log of the passenger service system, and based on the operation log of the passenger service system, query the broadcast controller information of the broadcast controller of the platform corresponding to the platform code. The broadcast controller information includes the broadcast controller code.

[0074] As mentioned above, the passenger service system needs to parse the vehicle arrival information message, find the corresponding station broadcast controller through the station code, and send it to the corresponding station broadcast controller through the message queue component. Therefore, the PIS log mainly collects the broadcast controller information corresponding to the station code.

[0075] Therefore, after obtaining the platform code corresponding to the above vehicle arrival information, the platform code is used to query the broadcast controller information of the corresponding platform from the operation log of the passenger service system. The broadcast controller information includes the broadcast controller code.

[0076] S103: Obtain the operation log corresponding to the station broadcast controller through broadcast controller encoding.

[0077] S104: Based on the operation log of the platform broadcast controller, query the display time when the platform broadcast controller pushes the vehicle arrival information to the broadcast control interface of the platform broadcast controller.

[0078] Since there are multiple station broadcast controllers, after finding the broadcast controller code corresponding to the vehicle arrival information, the corresponding operation log of the station broadcast controller can be obtained through the broadcast controller code.

[0079] As mentioned above, the PIPD log mainly collects the consumption time of vehicle arrival information and the final display time on the platform broadcast controller interface. Therefore, by parsing the corresponding operation log of the platform broadcast controller, the display time when the platform broadcast controller pushes the vehicle arrival information to the platform broadcast controller interface can be quickly queried.

[0080] S105: Determine the display time difference of vehicle arrival information based on the sending time and display time of vehicle arrival information.

[0081] After obtaining the transmission time of the train arrival information sent by the Automatic Train Monitoring System (ATS) and the display time of the train arrival information pushed to the platform broadcast controller's interface, the display time difference of the train arrival information can be directly obtained based on the transmission time and display time of the train arrival information sent by the ATS. The display time difference is calculated as: Display Time - ATS Transmission Time.

[0082] As can be seen from the embodiments of this application, the display time difference acquisition method provided in this application has the following characteristics compared with existing solutions:

[0083] 1. The existing method involves using the passenger service system to obtain screenshots of the station broadcast controllers after the Automatic Train Monitoring System (ATS) issues arrival information. The accuracy of the displayed arrival information is then confirmed by examining the screenshots. However, in this embodiment, the arrival information from the ATS is used as the source. Similar to following a map, the logs of the corresponding station broadcast controllers are located to determine the display time of the arrival information. Then, the ATS sending and display times can be directly used to accurately calculate the display time difference of the arrival information. This display duration can be used to determine whether the arrival information is accurately refreshed on the station broadcast controller display interface.

[0084] 2. Existing methods still rely on personnel to patrol the station platforms and check whether the vehicle arrival information is displayed on the platform broadcast controllers in a timely manner. Given the increasing complexity of rail transit and the growing number of platform broadcast controllers, this method is extremely time-consuming and labor-intensive. In contrast, this application's embodiment uses log analysis, i.e., an information-based approach to find the time point from when the vehicle arrival information is sent to when it is finally displayed, and calculates the difference between these two times to quickly determine the timeliness of the vehicle arrival information display.

[0085] In one embodiment, such as Figure 4 As shown, after step S106, that is, after determining the display time difference of vehicle arrival information, the method further includes the following steps:

[0086] S106: Determine whether the display time difference is greater than the preset response time.

[0087] The preset response time is a duration set according to the required response time of each level of the system. If the display time is longer than the preset response time, it means that there are some transmission chain response processes in the process of the vehicle arrival information being transmitted from the train automatic monitoring system to the corresponding platform broadcast controller, resulting in a large final display time difference.

[0088] S107: If the display duration exceeds the preset response duration, the display time difference is determined to be abnormal, and the abnormal display time difference is recorded.

[0089] S108: If the display duration is less than or equal to the preset response duration, the display time difference is determined to be normal.

[0090] For example, if the preset response time is 20 milliseconds, and the display time difference is 30 milliseconds, it means that the display time difference of this vehicle arrival information is less than the preset response time. In this case, the display time difference is considered abnormal, and it is recorded for subsequent maintenance to confirm the cause of the longer display time difference. If the display time difference is 15 milliseconds, it means that the display time difference of this vehicle arrival information is less than the preset response time. In this case, the display time difference of the vehicle arrival information by the station broadcast controller is within the preset range, indicating that the display time difference of this refreshed vehicle arrival information is normal.

[0091] In one embodiment, after step S107, that is, after determining that the displayed time difference is abnormal, the method further includes the following steps:

[0092] S109: Based on the operation logs of each level of system during the transmission of vehicle arrival information from the train automatic monitoring system to the platform broadcast controller, query the corresponding record information of each level of system for vehicle arrival information. The record information includes the sending time, receiving time and processing time of vehicle arrival information.

[0093] In this embodiment, the system retrieves the records of vehicle arrival information from each level of the system during the transmission of vehicle arrival information from the Automatic Train Monitoring System (ATMS) to the platform broadcast controller, based on the operation logs of each level of the system. It should be noted that in some embodiments of this application, the system can also retrieve the records of vehicle arrival information from each level of the system during the transmission of vehicle arrival information from the AMS to the platform broadcast controller before determining that the displayed time difference is abnormal. No specific limitations are imposed.

[0094] In one embodiment, the aforementioned systems at each level include an automatic train monitoring system, an integrated monitoring system, a passenger service system, a message queue component, and a platform broadcast controller.

[0095] As described above, the process of transmitting vehicle arrival information to the platform broadcast controller involves multiple different professional systems. The logs of each system level record information related to the vehicle arrival information. Accordingly, in one embodiment, querying the vehicle arrival information records of each system level includes the following steps:

[0096] S1091: By using the station code, query the operation log of the integrated monitoring system to find the time when the integrated monitoring system receives and transmits vehicle arrival information.

[0097] That is, the ISCS receive time and ISCS send time can be obtained by querying the ISCS log.

[0098] S1092: Query the passenger service system's operation log for the time it receives, processes, and sends vehicle arrival information by using the platform code.

[0099] That is, the PIS reception time, PIS processing time and PIS sending time can be queried from the PIS log.

[0100] S1093: Query the topic of vehicle arrival information and the time when the message queue component forwards the vehicle arrival information to the message queue through the message queue component's runtime log.

[0101] S1094: Query the consumption time of the station broadcast controller from the topic by using the broadcast controller code.

[0102] That is, it will query the MQ logs to find the time when the message queue component forwards the vehicle arrival information to the message queue, which is the MQ forwarding time, and parse the topic of the vehicle arrival information. Then, through the broadcast controller encoding, it will query the consumption time of the station broadcast controller consuming the vehicle arrival information from the topic, which is the PIPD consumption time.

[0103] S1095: Query the station broadcast controller's reception time and processing time for vehicle arrival information through the corresponding operation log.

[0104] It is understandable that when the platform broadcast controller consumes vehicle arrival information from the message queue, it needs to parse the vehicle arrival information before it can be updated to the interface for display. That is, the consumption includes the specific receiving time and processing time.

[0105] In one embodiment, before step S109, before querying the record information of vehicle arrival information of each level system, the method further includes the following steps:

[0106] S112: Obtain vehicle arrival information from the log system. The logs of each level of the system during the transmission process from the train automatic monitoring system to the platform broadcast controller are used to collect and store the operation logs of each level of the system.

[0107] In other words, in this embodiment, the vehicle arrival information processing system also includes a log system, which can be used to collect and store the operation logs of each level of the system, namely, to collect ATS logs, ISCS logs, PIS logs, MQ logs, and PIPD logs. Thus, in the display time difference acquisition method provided in this application embodiment, the operation logs of each level of the system can be directly extracted from this log system to query or parse the required relevant time.

[0108] S110: Based on the vehicle arrival information recorded by each level of the system and the required response time of each level of the system, determine whether the actual response time of each level of the system to the vehicle arrival information meets the required response time of that level of the system.

[0109] S111: If the actual response time of a certain level system does not meet the required response time for that level system, then the actual response time of that level system is determined to be abnormal, and the level system with the abnormal actual response time is recorded.

[0110] After obtaining the vehicle arrival information records from each level of the system, the actual response time of each level of the system can be obtained. For example, taking the transmission link between the integrated monitoring system and the passenger service system as an example, the passenger service system's response to this vehicle arrival information can be obtained based on the difference between the ISCS sending time and the PIS receiving time. If the difference between the ISCS sending time and the PIS receiving time exceeds the originally required response time, it indicates that there is an anomaly in the transmission link between the integrated monitoring system and the passenger service system. Therefore, it can be determined that the actual response time of the passenger service system does not meet the requirements; conversely, it can be determined that the actual response time of the passenger service system meets the requirements.

[0111] For example, taking PIS processing time as an example, if the PIS processing time retrieved from the PIS logs is longer than the processing time originally required by the passenger service system, it means that the actual processing response time of the passenger service system for vehicle arrival information does not meet the required response time. Conversely, it means that the actual processing response time of the passenger service system for vehicle arrival information meets the required response time. Similarly, other times or systems are handled in a similar manner; specific examples are not provided here.

[0112] As can be seen from the above embodiments, the recording time of each transmission chain process can be analyzed by using the operation logs of each level of the vehicle arrival information system. Therefore, when the display time difference of the vehicle arrival information displayed by the final station broadcast controller is abnormal, it can be quickly determined which level of system or which transmission chain has a problem by querying the operation logs of each level of system. This helps to quickly locate the abnormal problem and facilitates subsequent maintenance.

[0113] In addition, in this embodiment, it is not necessary to modify a large number of interfaces of the original systems at each level, nor is it necessary to modify the existing systems at each level. Only the operation logs of each system at each level need to be collected and the log data can be effectively analyzed, which is extremely convenient.

[0114] In one embodiment, after step S101, after obtaining the transmission time of the train arrival information issued by the automatic train monitoring system, the method further includes the following steps:

[0115] S113: Generate a unique record identifier for vehicle arrival information using the platform code and the starting recording time.

[0116] S114: Bind the queried vehicle arrival information records from each level of the system to the unique record identifier and record them in the statistical database.

[0117] In this embodiment, to form effective data records, after obtaining the transmission time of the vehicle arrival information issued by the Automatic Train Monitoring System (ATS), the system's operation logs are analyzed to summarize the log data of externally transmitted vehicle arrival information. The ATS transmission time is parsed, and a unique record identifier is generated. Each vehicle arrival information is saved to the statistical database in a key-value pair format, ordered in ascending order by time. The message body, platform code, and vehicle code corresponding to the ATS transmission time are also saved. Simultaneously, related records of this vehicle arrival information retrieved from other systems are also uniquely identified and recorded in the statistical database. The specific process is as follows:

[0118] By querying the vehicle arrival information reception time and transmission time through the operation log of the integrated monitoring system, these times are also stored in the statistical database. That is, the record data queried from the operation log of the integrated monitoring system needs to be bound one-to-one with the vehicle arrival information sent by the automatic train monitoring system.

[0119] Based on the station codes in the operation logs of the integrated monitoring system, the operation logs of the passenger service system are queried to obtain the reception time, processing time, and transmission time of vehicle arrival information. Furthermore, the station code is used to retrieve the broadcast controller information of multiple station broadcast controllers for the corresponding station. This broadcast controller information includes the broadcast controller code, target message queue address, and topic. Therefore, it is necessary to synchronously record the broadcast controller codes, target message queue addresses, and topics of the aforementioned multiple station broadcast controllers and store them in the statistical database along with a unique record identifier. It should be noted that this stage involves a single vehicle arrival information being sent to multiple station broadcast controllers for display. Therefore, it is necessary to establish a one-to-many relationship between vehicles and station broadcast controllers in the statistical database.

[0120] After collecting the operation logs of the message queue component and filtering out information related to the vehicle arrival information topic, the system queries the consumption time of each station's broadcast controller from the message queue based on the broadcast controller codes collected by the passenger service system. The consumption time is then associated with a unique record identifier and stored in the statistical database.

[0121] Based on the station broadcast controller's operation log corresponding to the broadcast controller code, query the vehicle arrival information reception time, processing time, and display time pushed to the interface, and also associate these times with unique record identifiers and store them in the statistical database.

[0122] In this embodiment, the relevant time information and broadcast controller information of each vehicle arrival information are linked and recorded through a statistical database to obtain correlation data that is conducive to analysis. This facilitates the identification of abnormal problem time points and the tracing of subsequent maintenance, and has strong practicality.

[0123] In one embodiment, a time difference monitoring system is provided, including a time difference acquisition device, an automatic train monitoring system, a passenger service system, and a platform broadcast controller;

[0124] The Automatic Train Monitoring System (ATMS) is used to acquire vehicle arrival information. It transmits the vehicle arrival information to the passenger service system through the integrated monitoring system and records the transmission time of the vehicle arrival information in the operation log of the AMS. The vehicle arrival information includes the platform code.

[0125] The passenger service system is used to parse vehicle arrival information to obtain platform codes, query the corresponding broadcast controller codes based on the platform codes, and push the vehicle arrival information to the platform broadcast controllers corresponding to the broadcast controller codes.

[0159] As can be seen from the embodiments of this application, the time difference monitoring system provided in this application has the following characteristics compared with existing solutions:

[0160] The existing method involves using the passenger service system to obtain screenshots of the platform broadcast controllers after the Automatic Train Monitoring System (ATS) issues arrival information. The accuracy of the displayed arrival information is then confirmed by examining the screenshots. In this embodiment, however, the arrival information from the ATS is used as the source. Similar to following a map, the logs of the corresponding platform broadcast controllers are located to determine the display time of the arrival information. The ATS sending and display times can then be directly used to accurately calculate the display time difference of the arrival information. This display duration can be used to determine whether the arrival information is accurately refreshed on the platform broadcast controller's display interface. Furthermore, existing methods also rely on personnel to inspect the platform broadcast controllers to ensure timely display of arrival information. Given the increasing complexity of rail transit and the growing number of platform broadcast controllers, this method is extremely time-consuming and labor-intensive. This embodiment, however, uses log analysis to locate the time between the issuance and final display of the arrival information. The difference between these two times is then calculated to quickly determine the timeliness of the arrival information display.
