[0061] 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.

[0062] The location report generation method provided in this application embodiment can be applied to, for example, Figure 1 In the application environment shown, the server determines the first vehicle direction of the target train based on the second train control system. The server then determines the validity of the target train's direction based on the relative direction information and the first vehicle direction. If the direction is valid, a second onboard position report of the target train's second train control system is generated based on the relative direction information and position prediction information. Specifically, the server obtains the first onboard position report of the target train from the China Train Control System; this first onboard position report includes the relative direction information of the target train relative to the associated transponder group and the target train's position prediction information.

[0063] The first train control system can be the CTCS (China Train Control System). The CTCS system is used to ensure train operation safety, improve transportation efficiency, and achieve intelligent management of train operations. As one of the core technologies of China's railways, the CTCS system is divided into multiple levels according to the needs of different lines, adapting to different application scenarios from conventional railways to high-speed railways. Specifically, CTCS-2 level is used for high-speed railways with speeds of 200-250 km / h. Based on track circuits and transponders, it achieves continuous speed monitoring and generates a CTCS onboard position report, i.e., the first onboard position report.

[0064] The second train control system can be a CBTC (Communication-Based Train Control) system. This system is an advanced train control system that uses highly reliable wireless / wired communication technology to achieve real-time data interaction between the train and ground equipment. It replaces traditional track circuits with continuous two-way train-to-ground communication, enabling precise train positioning, dynamic interval control, and automated operation. It is a core technology of modern urban rail transit (metro, light rail) and some railway systems.

[0065] The service end refers to a service device for generating a second on-board position report of a second train control system based on a first on-board position report of a first train control system. The service end can be a separate device, a device in the first train control system, or a device in the second train control system. When the service end is a separate device, it can be a server or a server cluster.

[0066] In one embodiment, as shown in Figure 2 , a position report generation method is provided. The method is described below by taking the service end in Figure 1 as an example, which includes the following steps:

[0067] S201, obtaining a first on-board position report of a target train of a first train control system.

[0068] The first on-board position report, i.e., the CTCS on-board position report, is a position report of the target train at a target time (e.g., the current time or a historical time) generated based on the CTCS system. The on-board position report includes relative direction information of the target train relative to an associated balise group and position prediction information of the target train. The relative direction information refers to the relative direction information of the target train relative to the defined direction of the associated balise group. In this application, the balise group is the Location Reference Balise Group (LRBG). The position prediction information refers to the position estimation information of the target train at the target time estimated based on the position information of the associated balise group.

[0069] As an optional implementation of the embodiment of the present application, the first on-board position report of the target train sent by the CTCS system is received.

[0070] As another optional implementation of the embodiment of the present application, a position report acquisition request is sent to the CTCS system, and the train identification of the target train is carried in the position report acquisition request. The CTCS system feeds back the first on-board position report of the target train to the service end based on the position report acquisition request.

[0071] S202, determining a first vehicle running direction of the target train according to the second train control system.

[0072] The first vehicle running direction refers to the running direction of the target train at the target time obtained based on the CBTC system.

[0073] As an optional implementation of the embodiment of the present application, the first vehicle running direction of the target train pushed by the CBTC system is received.

[0074] As another optional implementation of the embodiment of the present application, a position acquisition request is sent to the CBTC system, wherein the train identifier of the target train is carried in the position acquisition request, so that the CBTC system feeds back the first vehicle running direction of the target train to the server based on the position acquisition request.

[0075] In S203, the direction validity of the target train is determined according to the relative direction information and the first vehicle running direction.

[0076] Optionally, in the embodiment, the second vehicle running direction of the target train is determined based on the relative direction information. The second vehicle running direction and the first vehicle running direction are compared. If the running directions are consistent, the direction validity of the target train is valid. Otherwise, the direction validity of the target train is invalid.

[0077] In S204, the second on-board position report of the second train control system of the target train is generated according to the relative direction information and the position prediction information, in the case that the direction validity is valid.

[0078] The second train control system can be a CBTC (Communication-Based Train Control) system. The second on-board position report, i.e., the CBTC on-board position report, is a on-board position report of the target train at a target time generated based on the relative direction information and the position prediction information and meeting the requirements of the CBTC system.

[0079] Optionally, in the embodiment, a second on-board position report template is first acquired, and the template content is determined based on the relative direction information and the position prediction information. The template content is added to the second on-board position report template to obtain the second on-board position report of the target train.

[0080] In the embodiment, a first vehicle-mounted position report of the target train is acquired; wherein the first vehicle-mounted position report comprises relative direction information of the target train relative to the associated balise group and position prediction information of the target train. According to the CBTC system, a first vehicle running direction of the target train is determined. According to the relative direction information and the first vehicle running direction, a direction validity of the target train is determined. In a case where the direction validity is valid, a second vehicle-mounted position report of a second train control system of the target train is generated according to the relative direction information and the position prediction information. In the application, by acquiring the first vehicle-mounted position report of the target train and finally generating the second vehicle-mounted position report of the second train control system of the target train according to the information recorded in the first vehicle-mounted position report, not only the interconnection and intercommunication of the CTCS system and the CBTC system are realized, but also the second vehicle-mounted position report of the second train control system of the target train is generated based on the first vehicle-mounted position report, thereby reducing the calculation burden of the CBTC system and improving the resource utilization rate of the CTCS system.

[0081] In one embodiment, in order to improve the accuracy and effectiveness of the second vehicle-mounted position report, as shown in S203, an optional implementation manner comprises: Figure 3

[0082] S301, determining a direction consistency result according to the device activation direction and the estimated front end direction.

[0083] Wherein, the balise group is installed on or beside the track of the target train. The target train has a vehicle-mounted device associated with the balise group, and the vehicle-mounted device can read the electromagnetic signal generated by the balise group when the vehicle-mounted device is close to the balise group. The device activation direction refers to the device activation direction of the vehicle-mounted device relative to the defined direction of the balise group, for example, forward or reverse. The estimated front end direction refers to the current front end direction of the target train relative to the defined direction of the balise group. The train running direction refers to the running direction of the target train at the target time determined based on the balise group.

[0084] Optionally, in the embodiment, the first running direction of the target train is determined based on the device activation direction. The second running direction of the target train is determined based on the estimated front end direction. The direction consistency result is determined based on the first running direction and the second running direction. For example, if the first running direction is the same as the second running direction, the direction consistency result is consistent. If the first running direction is not the same as the second running direction, the direction consistency result is inconsistent.

[0085] S302, determining the direction validity of the target train according to the direction consistency result, the train running direction and the first vehicle running direction.

[0086] ​Optionally, in the case where the direction consistency result is consistent, the train running direction and the first vehicle running direction are compared to obtain a comparison result. According to the comparison result, the direction validity of the target train is determined. Specifically, in the case where the direction consistency result is consistent, the train running direction and the first vehicle running direction are compared to obtain a comparison result. If the train running direction and the first vehicle running direction are the same, the comparison result is the same direction. If the train running direction and the first vehicle running direction are not the same, the comparison result is different directions. In the embodiment, the optional implementation of determining the direction validity of the target train according to the comparison result is that, if the comparison result is the same direction, the direction validity of the target train is valid. If the comparison result is different directions, the direction validity of the target train is invalid.

[0087] In the embodiment, the direction consistency result is determined according to the device activation direction and the estimated front end direction. The direction validity of the target train is determined according to the direction consistency result, the train running direction and the first vehicle running direction. Only in the case where the direction validity of the target train is valid, the obtained on-board position report is accurate. Therefore, the effectiveness and accuracy of the second on-board position report are effectively improved based on the embodiment.

[0088] In one of the embodiments, in order to make the generated second on-board position report more valuable, more accurate and rich in content, as shown in Figure 4 An optional implementation of S204 includes:

[0089] S401, determining the maximum safe front end of the target train according to the train estimated front end and the over-reading error.

[0090] The train estimated front end refers to the estimated position of the front end of the train. The over-reading error refers to the error range in which the train may exceed the actual position.

[0091] Optionally, in the embodiment, the sum of the train estimated front end and the over-reading error is taken as the maximum safe front end of the target train, i.e., maximum safe front end = train estimated front end + over-reading error.

[0092] S402, determining the maximum safe rear end of the target train according to the train estimated front end, the train length and the over-reading error.

[0093] The train length refers to the length of the target train. The maximum safe rear end refers to the position of the maximum rear end of the target train.

[0094] Optionally, in the embodiment, the difference between the column and the estimated front end of the train and the train length is taken as the first value. The sum of the first value and the over-reading error is taken as the maximum safe rear end of the target train. That is, the maximum safe rear end = (estimated front end of the train - train length) + over-reading error.

[0095] S403, generating the second on-board position report of the second train control system of the target train according to the maximum safe front end, the maximum safe rear end, the relative direction information and the position prediction information.

[0096] Optionally, in the embodiment, the predicted section information of the target train is determined according to the maximum safe front end and the maximum safe rear end. The section validity result of the target train is determined according to the predicted section information of the target train and the current section information. In the case that the section validity result is valid, the second on-board position report of the second train control system of the target train is generated according to the relative direction information and the position prediction information. In the embodiment, one optional implementation of determining the predicted section information of the target train according to the maximum safe front end and the maximum safe rear end is that the section information of the maximum safe front end is determined according to the maximum safe front end. For example, the maximum safe front end is compared with the section range of each section to obtain the section information of the maximum safe front end, such as section ID. The section information of the maximum safe rear end is determined according to the maximum safe rear end. The section information of the maximum safe front end and the section information of the maximum safe rear end are taken as the predicted section information of the target train. If the predicted section information is the same as or close to the current section information, the section validity result is determined to be valid.

[0097] Optionally, the optional implementation of generating the second on-board position report of the second train control system of the target train according to the relative direction information and the position prediction information in the embodiment is that the position prediction information further comprises an under-reading error, which refers to an error that the target train may not reach the actual position. On this basis, the optional implementation of generating the second on-board position report of the second train control system of the target train according to the relative direction information and the position prediction information is that the segment identifier of the maximum safe front end and the intra-segment offset of the maximum safe front end are determined according to the maximum safe front end and the current segment information. The segment identifier of the minimum safe front end and the intra-segment offset of the minimum safe front end are determined according to the train estimated front end and the under-reading error. The segment identifier of the maximum safe rear end and the intra-segment offset of the maximum safe rear end are determined according to the maximum safe rear end and the current segment information. The segment identifier of the minimum safe rear end and the intra-segment offset of the minimum safe rear end are determined according to the train estimated front end, the train length and the under-reading error. The second on-board position report of the second train control system of the target train is generated according to the train running direction in the relative direction information, the segment identifier of the maximum safe front end, the intra-segment offset of the maximum safe front end, the segment identifier of the minimum safe front end, the intra-segment offset of the minimum safe front end, the segment identifier of the maximum safe rear end, the intra-segment offset of the maximum safe rear end, the segment identifier of the minimum safe rear end and the intra-segment offset of the minimum safe rear end. In the embodiment, the intra-segment offset refers to a dynamic deviation in the segment. Taking the maximum safe front end as an example, the intra-segment offset of the maximum safe front end refers to a dynamic deviation of the actual front end position of the target train in the segment corresponding to the maximum safe front end. The optional implementation of determining the segment identifier in the embodiment is that, taking the determination of the segment identifier of the maximum safe front end as an example, the candidate segment containing the maximum safe front end in the segment range is determined as the target segment according to the maximum safe front end and the segment range of each candidate segment. The segment identifier of the target segment is determined as the segment identifier of the maximum safe front end. The optional implementation of determining the segment identifier of the minimum safe front end according to the train estimated front end and the under-reading error in the embodiment is that the difference between the train estimated front end and the under-reading error is determined as the minimum safe front end. The segment identifier of the segment where the minimum safe front end is located is determined as the segment identifier of the minimum safe front end. The optional implementation of determining the segment identifier of the minimum safe rear end according to the train estimated front end, the train length and the under-reading error in the embodiment is that the difference between the train estimated front end and the train length is determined as a second value. The difference between the second value and the under-reading error is determined as the minimum safe rear end. The segment identifier of the segment where the minimum safe rear end is located is determined as the segment identifier of the minimum safe rear end.In the embodiment, the optional implementation of generating the second on-board position report of the second train control system of the target train according to the train running direction in the relative direction information, and the section identification of the maximum safe front end, the section offset of the maximum safe front end, the section identification of the minimum safe front end, the section offset of the minimum safe front end, the section identification of the maximum safe rear end, the section offset of the maximum safe rear end, the section identification of the minimum safe rear end and the section offset of the minimum safe rear end is adding the train running direction, and the section identification of the maximum safe front end, the section offset of the maximum safe front end, the section identification of the minimum safe front end, the section offset of the minimum safe front end, the section identification of the maximum safe rear end, the section offset of the maximum safe rear end, the section identification of the minimum safe rear end and the section offset of the minimum safe rear end into the second on-board position report template to obtain the second on-board position report.

[0098] In the embodiment, the maximum safe front end of the target train is determined according to the train estimated front end and the over-reading error. The maximum safe rear end of the target train is determined according to the train estimated front end, the train length and the over-reading error. The predicted section information of the target train is determined according to the maximum safe front end and the maximum safe rear end. The section effective result of the target train is determined according to the predicted section information of the target train and the current section information. The section identification of the maximum safe front end and the section offset of the maximum safe front end are determined according to the maximum safe front end and the current section information. The section identification of the minimum safe front end and the section offset of the minimum safe front end are determined according to the train estimated front end and the under-reading error. The section identification of the maximum safe rear end and the section offset of the maximum safe rear end are determined according to the maximum safe rear end and the current section information. The section identification of the minimum safe rear end and the section offset of the minimum safe rear end are determined according to the train estimated front end, the train length and the under-reading error. The second on-board position report of the second train control system of the target train is generated according to the train running direction in the relative direction information, and the section identification of the maximum safe front end, the section offset of the maximum safe front end, the section identification of the minimum safe front end, the section offset of the minimum safe front end, the section identification of the maximum safe rear end, the section offset of the maximum safe rear end, the section identification of the minimum safe rear end and the section offset of the minimum safe rear end. Based on the embodiment, the accuracy and richness of the content of the obtained second on-board position report are further increased, and the generated second on-board position report has more reference value.
