[0014] In addition, it should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in one or more embodiments of this specification are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0015] First, the terms involved in one or more embodiments of this specification are explained.

[0016] Train safety protection distance: refers to the minimum safe distance that should be maintained between two trains or between a train and an obstacle in railway transportation, in order to ensure the safety of train operation, prevent collisions between trains or provide sufficient braking space to avoid collisions, based on the train running speed, braking performance, signal system control capabilities and other operating conditions.

[0017] In the current practical application of rail transit, in order to ensure the safe operation of trains, a train safety protection distance is usually set, and mobile authorization is set based on the train safety protection distance, so that the train can control the operation of the train according to the set train safety protection distance during operation. However, in the actual operation of the train, there may be abnormal train communication, slippery lines, icing caused by the influence of the meteorological environment, and other phenomena. In these scenarios, the train may not be able to continue to operate according to the set train safety protection distance, and the safety of the train operation may not be guaranteed. Therefore, it is particularly important to update the train safety protection distance of the train in real time according to the actual environment of the train operation.

[0018] In this specification, a method for adjusting a train safety protection distance is provided. This specification also relates to a train safety protection distance adjustment device, a computing device, a computer-readable storage medium, and a computer program product, which are described in detail one by one in the following embodiments.

[0019] See also Figure 1 , Figure 1 The following is a schematic diagram showing an application scenario of a method for adjusting a train safety protection distance according to an embodiment of this specification. Figure 1 As shown in the application scenario of rail transit, during the operation of trains, it is necessary for trains to maintain a certain safety protection distance between each other (for example, Figure 1 As shown), to prevent the current train from rear-ending the train in front and causing a safety accident. In practical applications, a basic safety protection distance is often set in advance so that during the operation of the train, the train can be controlled according to the pre-set basic safety protection distance to achieve operations such as traction and braking of the train. However, the operation scenarios of trains are often changeable. For example, a train may encounter sudden heavy rain or heavy snow during operation. At this time, the train line may be slippery due to heavy rain or heavy snow, and the train may not be able to continue to operate at the basic safety protection distance. Based on this, it is necessary to redetermine the corresponding safety protection distance of the train according to the current operation scenario of the train to ensure that the train can continue to operate at the new safety protection distance, thereby ensuring the safety of the train operation.

[0020] In the method for adjusting the train safety protection distance provided in this specification, when it is determined that the train needs to adjust the safety protection distance, the current safety protection distance and the preset attribute distance set of the train can be obtained. After identifying at least one current operation scenario in which the train is located, the target attribute distance data and the corresponding target protection weights corresponding to the multiple current operation scenarios are screened in the preset attribute distance set, so as to determine the target expected safety protection distance corresponding to the multiple current operation scenarios in which the train is located at this time according to the target attribute distance data and the corresponding target protection weights corresponding to each current operation scenario. Then, based on the determined target expected safety protection distance, the corresponding safety protection distance to be determined in the target attribute distance data of the train in different operation scenarios is determined, so that the target safety protection distance of the train can be determined according to the safety protection distance to be determined corresponding to different current operation scenarios and the target protection weights corresponding to different current operation scenarios, and the current safety protection distance of the train obtained is adjusted to the determined target safety protection distance. In the subsequent operation process, the train can continue to operate at the target safety protection distance.

[0021] An embodiment provided in the present specification realizes that, during the operation of a train, by identifying various operating scenarios in which the train is located, and integrating the basic safety protection distances and protection weights pre-set for the train under various operating scenarios, the target safety protection distance of the train after adjustment is determined under the various operating scenarios at this time, so that the train can continue to operate at the target safety protection distance, thereby further ensuring the safety of the train operation without affecting the train operation.

[0022] See also Figure 2 , Figure 2 shows a flowchart of a method for adjusting the train safety protection distance provided according to an embodiment of this specification, which specifically includes the following steps: Step 202: Obtain the current safety protection distance of the target train and the preset attribute distance set.

[0023] Among them, the target train refers to any train during the train operation. The current safety protection distance refers to the train safety protection distance of the target train at the current operation moment or within the current operation time interval. The preset attribute distance set includes the preset safety protection distances and preset protection weights corresponding to different operation scenarios set in advance. The operation scenarios can specifically include standard operation scenarios and abnormal operation scenarios, etc. The standard operation scenario is the scenario where the train operates normally; the abnormal operation scenario can specifically include the first abnormal operation scenario, for example, train communication failure, etc., and can also include the second abnormal operation scenario, for example, the train line track is frozen, the train line track is slippery, etc. Based on this, the first abnormal operation scenario refers to the scenario where the train operation scenario is abnormal due to the abnormality of the train attribute information; the second abnormal operation scenario refers to the scenario where the train operation scenario is abnormal due to the external environment. For the above standard operation scenario, the first abnormal operation scenario, and the second abnormal operation scenario, different preset protection weights can be set respectively. For example, set the preset protection weight of the standard operation scenario as S, set the preset protection weight of the first abnormal operation scenario as A, and set the preset protection weight of the second abnormal operation scenario as E, and S < A < E. To determine the influence degree of different influencing factors on the train operation in different operation scenarios, the preset safety protection distances corresponding to different operation scenarios can be set by setting protection dimensions. In one or more embodiments provided in this specification, the preset protection dimensions of the preset safety protection distances in different operation scenarios can be determined as dimensions such as hazard degree, response time, braking distance, and braking rate. Specifically, the hazard degree can be specifically represented by Hd, the response time can be specifically represented by Rt, the braking distance can be specifically represented by Bd, and the braking rate can be specifically represented by Br.

[0024] During the operation of the target train, if it is determined that the operation scenario of the target train has changed and the current safety protection distance of the target train needs to be adjusted, the current safety protection distance of the target train and the preset attribute distance set can be obtained to determine the safety protection distance required for the target train in the subsequent operation process through the preset attribute distance set.

[0025] Step 204: Identify at least one current operation scenario where the target train is located, and filter the target attribute distance data and the target protection weights corresponding to each current operation scenario from the preset attribute distance set according to the current operation scenarios where the target train is located.

[0026] In practical applications, since the preset attribute distance set includes the preset safety protection distances and preset protection weights corresponding to the train in different operating scenarios, after obtaining the current safety protection distance and preset attribute distance set of the target train, it is necessary to identify the current operating scenario of the target train to determine which operating scenarios the target train is in at this time, and thus, determine the preset attribute distance data required for the operating scenario of the target train in the preset attribute distance set according to the operating scenario of the target train.

[0027] Among them, the current operation scenario refers to the operation scenario of the target train at the current moment or in the current time interval. In actual applications, the current operation scenario can be one or more. This specification does not limit the number of current operation scenarios, which can be determined according to actual application conditions. For example, the current operation scenario of the target train can be at least one of the standard operation scenario, the first abnormal operation scenario, and the second abnormal operation scenario. Target attribute distance data refers to the preset attribute distance data corresponding to each current operation scenario, which can be specifically understood as a preset safety protection distance. Target protection weight refers to the preset protection weight corresponding to each current operation scenario.

[0028] Specifically, by identifying at least one current operating scenario in which the target train is located, and based on the current operating scenario in which the target train is located, in the preset attribute distance set, the preset safety protection distance corresponding to each current operating scenario is determined as the target attribute distance data, and the preset protection weight corresponding to each target operating scenario is determined as the target protection weight.

[0029] In practical applications, the current operating scenario of the target train may be related to the train attribute information of the target train itself, or may be related to the current operating environment of the target train. Therefore, in the process of identifying the current operating scenario of the target train, it can be identified specifically based on the train attribute information of the target train and the current operating environment.

[0030] In a specific implementation manner provided in this specification, identifying at least one current operation scenario of the target train includes: Identifying train attribute information of the target train, and generating an attribute identification result of the target train according to the train attribute information; Identifying a current operating environment of the target train, and generating an environment identification result of the target train according to the current operating environment; The current operation scenario of the target train is determined according to the attribute recognition result and the environment recognition result.

[0031] Among them, train attribute information refers to the attribute information of the target train itself, such as the communication system information of the target train, the automatic protection system information of the target train, etc. The attribute recognition result refers to the recognition result generated after abnormal recognition of the train attribute information of the target train. The current operating environment refers to the operating environment of the target train at the current moment or in the current time interval, such as ice on the train line track, slippery train line track, etc. The environment recognition result refers to the recognition result generated after abnormal recognition of the current operating environment of the target train.

[0032] Specifically, by performing abnormal identification on the train attribute information of the target train, an attribute identification result of the target train is generated, so as to determine whether the train attribute information of the target train is abnormal according to the attribute identification result. Performing abnormal identification on the current operating environment of the target train, an environment identification result of the target train is generated, so as to determine whether the current operating environment of the target train is abnormal according to the environment identification result. After obtaining the attribute identification result and the environment identification result of the target train, the current operating scene of the target train can be determined according to the attribute identification result and the environment identification result.

[0033] Further, in a specific implementation manner provided in this specification, determining the current operation scene of the target train according to the attribute recognition result and the environment recognition result includes: When the attribute recognition result shows an abnormality and the environment recognition result shows no abnormality, determining that the current operation scenario of the target train is a first abnormal operation scenario; When the attribute recognition result does not show abnormality and the environment recognition result shows abnormality, determining that the current operation scenario of the target train is a second abnormal operation scenario; When the attribute recognition result shows abnormality and the environment recognition result shows abnormality, determining that the current operation scenario of the target train is a first abnormal operation scenario and a second abnormal operation scenario; When the attribute recognition result does not show an abnormality and the environment recognition result does not show an abnormality, it is determined that the current operation scenario of the target train is a standard operation scenario.

[0034] After obtaining the attribute recognition result and the environment recognition result of the target train, determine whether the train attribute information of the target train is abnormal, and whether the environment recognition information of the target train is abnormal. If the attribute recognition result of the target train shows an abnormality, and the environment recognition result does not show an abnormality, it means that the train attribute information of the target train is abnormal, but the current operating environment is not abnormal. At this time, it can be determined that the current operating scene of the target train is the first abnormal operating scene. If the attribute recognition result of the target train does not show an abnormality, and the environment recognition result shows an abnormality, it means that the train attribute information of the target train is not abnormal, but the current operating environment is abnormal. At this time, it can be determined that the current operating scene of the target train is the second abnormal operating scene. If the attribute recognition result of the target train shows an abnormality, and the environment recognition result also shows an abnormality, it means that both the train attribute information and the current operating environment of the target train are abnormal. At this time, it can be determined that the current operating scene of the target train is the superposition scene of the first abnormal operating scene and the second abnormal operating scene. If the attribute identification result of the target train does not show any abnormality, and the environment identification result also does not show any abnormality, it means that there is no abnormality in the train attribute information and the current operating environment of the target train. At this time, it can be determined that the current operating scenario of the target train is the standard operating scenario.

[0035] The train safety protection distance adjustment method provided in this specification can detect whether there are any abnormalities in the train attribute information and the current operating environment of the target train by performing abnormal identification on the train attribute information and the current operating environment of the target train, thereby determining the current operating scenario of the target train, which is conducive to the subsequent dynamic adjustment of the safety protection distance of the target train in real time according to the different operating scenarios of the target train.

[0036] Step 206: Determine the target expected safety protection distance corresponding to the target train according to the target attribute distance data.

[0037] After determining the target attribute distance data, that is, the preset safety protection distance corresponding to the current operating scenario, according to the current operating scenario of the target train, the target expected safety protection distance of the target train can be further determined according to the target attribute distance data.

[0038] Among them, the target expected safety protection distance refers to the safety protection distance expected to be achieved after adjusting the current safety protection distance of the target train. The target expected safety protection distance specifically includes a positive expected safety protection distance and a negative expected safety protection distance. The positive expected safety protection distance refers to the better safety protection distance expected to be achieved after adjusting the current safety protection distance of the target train; the negative expected safety protection distance refers to the worse safety protection distance expected to be achieved after adjusting the current safety protection distance of the target train. The positive expected safety protection distance and the negative expected safety protection distance are used to screen the target safety protection distance after adjusting the current safety protection distance of the target train.

[0039] In a specific implementation manner provided in this specification, determining the target expected safety protection distance corresponding to the target train according to the target attribute distance data includes: Determining at least one preset protection dimension corresponding to the target train and the number of trains running on the line; According to each preset protection dimension, the running quantity and the target attribute distance data, a protection distance matrix corresponding to the target train in each current running scenario is constructed; According to each protection distance matrix, determine the target expected safety protection distance.

[0040] In practical applications, in order to determine the degree of influence of different influencing factors on the safety protection distance of the target train in different current operating scenarios of the target train, multiple protection dimensions can be pre-set for determination.

[0041] Among them, the preset protection dimensions refer to different dimensions used to evaluate the safety protection distance of the target train. The preset protection dimensions can specifically include dimensions such as hazard level, response time, braking distance and braking rate. The hazard level can be specifically represented by Hd, the response time can be specifically represented by Rt, the braking distance can be specifically represented by Bd, and the braking rate can be specifically represented by Br. The protection distance matrix is ​​a safety protection distance matrix constructed based on the preset protection dimensions and target attribute distance data. For details, please refer to the following formula 1: Formula 1 Among them, Z is the protection distance matrix; T x,Hd The hazard level dimension x The attribute distance data of the trains, that is, the first x Safety protection distance between two trains; T x,Rt The response time dimension x The attribute distance data of the trains, that is, the first x Safety protection distance between two trains;T x,Bd The braking distance dimension x The attribute distance data of the train, that is, the braking distance dimension x Safety protection distance between two trains; T x,Br The braking rate dimension x The attribute distance data of the train, that is, the braking rate dimension x Safety protection distance between two trains; x is the number of trains running on the line. The target trains are trains 1 to 2. x Any one of the trains.

[0042] Specifically, determine multiple preset protection dimensions corresponding to the target train and the number of line trains running on the train line. After obtaining the target attribute distance data, construct the protection distance matrix corresponding to the target train in different current operation scenarios according to the multiple preset protection dimensions, the number of line trains running and the target attribute distance data, that is, construct the standard protection distance matrix corresponding to the target train in the standard operation scenario, construct the first abnormal protection distance matrix corresponding to the target train in the first abnormal operation scenario, and construct the second abnormal protection distance matrix corresponding to the target train in the second abnormal operation scenario. According to the constructed standard protection distance matrix, the first abnormal protection distance matrix and the second abnormal protection distance matrix, determine the target expected safety protection distance, that is, the positive expected safety protection distance and the negative expected safety protection distance, which can be obtained by solving each protection distance matrix through the cosine method. The process of solving the positive expected safety protection distance can be seen in the following formula 2: Formula 2 in, Z Tx + is the positive expected safety protection distance; S is the preset protection weight of the standard operation scenario, A is the preset protection weight of the first abnormal operation scenario, and E is the preset protection weight of the second abnormal operation scenario; SL is the preset safety protection distance of the standard operation scenario, AL is the preset safety protection distance of the first abnormal operation scenario, and EL is the preset safety protection distance of the second abnormal operation scenario. The positive expected safety protection distance can be solved by the above formula 2.

[0043] Furthermore, the process of solving the negative expected safety protection distance can be referred to the following formula 3: Formula 3 in, Z Tx - is the negative expected safety protection distance. The negative expected safety protection distance can be solved by the above formula 3.

[0044] The train safety protection distance adjustment method provided in this specification combines different preset protection dimensions to solve the target expected safety protection distances under multiple current operating scenarios described by the target train, that is, the positive expected safety protection distance and the negative expected safety protection distance. The target expected safety protection distance of the target train can be obtained when multiple current operating scenarios are superimposed, making the target expected safety protection distance more credible.

[0045] Step 208: Determine the to-be-determined safety protection distance corresponding to the target train in each current operation scenario according to the target attribute distance data and the target expected safety protection distance.

[0046] After determining the target expected safety protection distance of the target train in different current operation scenarios, the corresponding safety protection distance to be determined can be determined in different current operation scenarios according to the target expected safety protection distance.

[0047] Among them, the safety protection distance to be determined refers to the safety protection distance determined in each current operation scenario for determining the target safety protection distance, that is, the safety protection distance determined based on each protection distance matrix for determining the target safety protection distance.

[0048] In a specific implementation manner provided in this specification, determining the to-be-determined safety protection distance corresponding to the target train in each current operation scenario according to the target attribute distance data and the target expected safety protection distance includes: Determining a protection distance matrix to be processed in each protection distance matrix, wherein the protection distance matrix to be processed is any one of the protection distance matrices; Inputting the protection distance matrix to be processed into a multi-attribute decision-making model to obtain at least one safety protection distance to be processed corresponding to the target train in the operation scenario to be processed; According to the target expected safety protection distance, the to-be-determined safety protection distance of the target train in the to-be-processed operation scenario is determined in each to-be-processed safety protection distance.

[0049] Among them, the protection distance matrix to be processed is any one of the protection distance matrices. The operation scenario to be processed refers to the operation scenario corresponding to the protection distance matrix to be processed in each current operation scenario. The multi-attribute decision model is used to generate multiple safety protection distances to be processed corresponding to each protection distance matrix. The safety protection distance to be processed refers to the solution of multiple safety protection distances output by the multi-attribute decision model, and the safety protection distance to be determined is one of the multiple safety protection distances to be processed.

[0050] Specifically, after constructing and obtaining each protection distance matrix, for any protection distance matrix (i.e., protection distance matrix to be processed), the protection distance matrix to be processed is input into the multi-attribute decision model, and multiple solutions output by the multi-decision attribute model can be obtained, that is, multiple safety protection distances to be processed corresponding to the operation scenario (i.e., operation scenario to be processed) corresponding to the protection distance matrix to be processed for the target train. Since the train cannot operate according to multiple safety protection distances in the actual operation scenario of the train, it is necessary to determine the safety protection distance to be determined among the multiple safety protection distances to be processed output by the multi-attribute decision model, so as to determine the target weighted protection distance for guiding the train operation according to the safety protection distance to be determined in the subsequent process. Specifically, the safety protection distance to be determined can be determined among the multiple safety protection distances to be processed according to the positive expected safety protection distance and the negative expected safety protection distance obtained by solving.

[0051] In one embodiment provided in this specification, a plurality of pending safety protection distances for determining a target safety protection distance are generated by a multi-attribute decision model, so that before determining the target safety protection distance, the multi-attribute decision model integrates multiple protection dimensions and outputs the pending safety protection distance. In order to ensure the accuracy of the target safety protection distance, the pending safety protection distance is further determined from the plurality of pending safety protection distances to improve the accuracy of determining the target safety protection distance.

[0052] The following is an explanation of a specific implementation process of determining a to-be-determined safety protection distance from a plurality of to-be-processed safety protection distances.

[0053] In a specific implementation manner provided in this specification, according to the target expected safety protection distance, determining the to-be-determined safety protection distance of the target train in the to-be-processed operation scenario in each to-be-processed safety protection distance includes: Determine a candidate safety protection distance among the safety protection distances to be processed, wherein the candidate safety protection distance is any one of the safety protection distances to be processed; Calculating the similarity to be processed between the candidate safety protection distance and the target expected safety protection distance; Determining, according to the to-be-processed similarity, a to-be-processed closeness between the candidate safety protection distance and the target expected safety protection distance; According to the pending approach degree, a pending safety protection distance of the target train in the pending operation scenario is determined.

[0054] Among them, the candidate safety protection distance is any one of the safety protection distances to be processed. The similarity to be processed refers to the similarity between the candidate safety protection distance and the target expected safety protection distance, which is used to characterize the degree of proximity between the candidate safety protection distance and the target expected safety protection distance. The similarity to be processed includes the positive similarity to be processed and the negative similarity to be processed. The positive similarity to be processed is the similarity between the candidate safety protection distance and the positive expected safety protection distance, and the negative similarity to be processed is the similarity between the candidate safety protection distance and the negative expected safety protection distance. The similarity to be processed can be obtained by calculating the Euclidean distance or cosine distance between the candidate safety protection distance and the target expected safety protection distance.

[0055] The pending closeness refers to the relative closeness between the candidate safety protection distance and the positive expected safety protection distance. It is calculated based on the pending positive similarity and the pending negative similarity.

[0056] Specifically, for any safety protection distance to be processed (i.e., candidate safety protection distance), the pending positive similarity between the candidate safety protection distance and the positive expected safety protection distance, and the pending negative similarity between the candidate safety protection distance and the negative expected safety protection distance are calculated respectively. According to the pending positive similarity and the pending negative similarity, the pending closeness between the candidate safety protection distance and the positive expected protection distance is calculated. After calculating the closeness between each safety protection distance to be processed and the positive expected safety protection distance, the safety protection distance to be determined is determined in each safety protection distance to be processed according to the closeness between each safety protection distance to be processed and the positive expected safety protection distance. Specifically, the safety protection distance to be processed with the largest closeness in numerical value is determined as the safety protection distance to be determined.

[0057] Furthermore, the process of calculating the degree of convergence between the to-be-processed safety protection distance and the positive expected safety protection distance is as follows: In a specific implementation provided in this specification, the similarity to be processed includes a positive similarity to be processed and a negative similarity to be processed, and the target expected safety protection distance includes a positive expected safety protection distance; Determining the degree of proximity between the candidate safety protection distance and the target expected safety protection distance according to the similarity to be processed, including: Calculating fusion similarity according to the positive similarity to be processed and the negative similarity to be processed; According to the to-be-processed negative similarity and the fused similarity, a to-be-processed closeness between the candidate safety protection distance and the positive expected safety protection distance is determined.

[0058] The fused similarity specifically refers to the summed similarity of the positive similarity to be processed and the negative similarity to be processed.

[0059] Specifically, according to the positive similarity to be processed and the negative similarity to be processed, the sum of the positive similarity to be processed and the negative similarity to be processed is calculated to obtain the fused similarity.
