[0054] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] In the embodiments of the present application, words such as "first" and "second" are used to distinguish between identical or similar items with basically the same functions and effects. This is only for the purpose of clearly describing the technical solutions of the embodiments of the present application, and shall not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0056] In the embodiments of the present application, the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0057] For the sake of convenience, the following is a glossary of terms used in the embodiments of the present invention:

[0058] Trajectory data: refers to data collected by IoT devices (such as GPS (Global Positioning System) locators, mobile phones, etc.), containing location information (longitude, latitude), timestamp, speed, etc.

[0059] Smart push: The process of dynamically adjusting the push strategy based on user subscription status and system status, and pushing trajectory data to users in a specified manner.

[0060] Comparison algorithm: Process trajectory data to generate comparison results with practical application value

[0061] (such as trajectory similarity, abnormal behavior detection, etc.)

[0062] Cache-database interaction: The process of storing the comparison results in the cache to improve query efficiency and periodically refreshing the data in the cache to the database.

[0063] Trajectory data refers to data collected by IoT devices (such as GPS locators, mobile phones, etc.), which contains location information (longitude, latitude), timestamp, speed, etc.

[0064] With the rapid development of the Internet of Things, big data and cloud computing technologies, the collection, processing and push of trajectory data have become key requirements in many application scenarios.

[0065] However, the trajectory data processing systems in related technologies often lack intelligence. Not only are they unable to flexibly adjust push strategies based on user subscriptions and business needs, but they also have low query efficiency and cannot meet users' real-time requirements for trajectory data push.

[0066] In order to solve the above problems, the present invention is based on the core technical concept of adaptively adjusting the push mode of trajectory data according to the actual subscription situation and business needs of the user, and improves the trajectory data push method in the related art. The present invention will be described in detail in conjunction with the accompanying drawings below:

[0067] Reference Figure 1 , shows a flow chart of a method for pushing trajectory data provided by some embodiments of the present invention, which may specifically include the following steps:

[0068] Step 101, in response to a track data subscription operation of a user, pushing track data to the user through a polling connection, and recording the polling frequency of the user;

[0069] In the specific implementation, Figure 2 As shown, the embodiment of the present invention can be implemented based on the following system architecture:

[0070] System architecture:

[0071] (1) Client: responsible for user subscription management and push reception.

[0072] (2) Server: includes intelligent push module, trajectory processing module and cache and data security module.

[0073] Intelligent push module: formulate push strategies based on user subscriptions and current system status, and push them to users.

[0074] Trajectory processing module: processes trajectory data according to comparison business requirements and generates comparison results.

[0075] Data security module: encrypt and desensitize data information to ensure the security of user-related information.

[0076] (3) Cache and database interaction module: The comparison results are stored in the cache and refreshed to the database at regular intervals.

[0077] (6) Database: responsible for the persistent storage of data.

[0078] On this basis, the trajectory data from the IoT device can be received through the server and stored in the trajectory data storage table. Then the intelligent push module can formulate a push strategy based on the user subscription status and the current system status, and push the trajectory data to the user according to the push strategy.

[0079] Specifically, the server can create a long polling connection for each user during initialization. This long polling connection can be used to continuously monitor the update of trajectory data. When the client subscribes to trajectory data, it can request data from the server by long polling by default. When there is no new trajectory data update, the server can keep the connection open until new data arrives or the connection times out. The polling frequency of each user can also be recorded, including the time interval and number of requests for each request, for subsequent steps.

[0080] In some embodiments of the present invention, before the step of pushing the trajectory data to the user through the polling connection in response to the user's trajectory data subscription operation, the step further includes:

[0081] In response to the initialization operation of the server, the polling connection is established between the server and each of the users.

[0082] In actual applications, the server can create a long polling connection for each user during initialization. This long polling connection can be used to continuously monitor the update of trajectory data. When the client subscribes to trajectory data, it can request data from the server through long polling by default. When there is no new trajectory data update, the server can keep the connection open until new data arrives or the connection times out.

[0083] Step 102, determining whether the polling frequency exceeds a preset threshold, and converting the polling connection into a real-time connection when the polling frequency exceeds the preset threshold; wherein the real-time connection is used to push the updated trajectory data to the user immediately when the trajectory data is updated;

[0084] In the specific implementation, Figure 3As shown in the figure, when it is detected that the polling frequency of the user exceeds the preset threshold (such as frequent requests and a short interval between each request), the server can determine that the user needs a more real-time data update. At this time, the server can convert the user's connection from a long polling connection to a long connection (i.e. a real-time connection, such as a WebSocket connection). A long connection allows the server to push data to the client immediately when the data is updated, without the client making frequent requests. After the conversion, the server can maintain a long connection list, monitor the connection status in real time, and ensure that the data can be pushed to the user accurately and promptly. If the user's heartbeat detection fails, the long connection list can remove the user.

[0085] Step 103: determine a push strategy, and push the trajectory data to the user according to the real-time connection and the push strategy.

[0086] In the specific implementation, the server can formulate a push strategy based on the type of trajectory data subscribed by the user, the polling frequency, and the push method requirements. The push strategy may include data screening rules, push time intervals, and push methods (such as SMS, email, APP push, etc.). Then, the corresponding push execution unit can push the trajectory data to the user in the specified manner according to the formulated push strategy. At the same time, the server can record the success or failure of each push for subsequent analysis and optimization of the push strategy.

[0087] In some embodiments of the present invention, determining the push strategy includes:

[0088] Determine the polling frequency information, push mode requirement information and track data type information subscribed by the user;

[0089] The push strategy is determined according to one or more of the polling frequency information, the push mode requirement information, and the type of trajectory data subscribed by the user.

[0090] In actual applications, the server can formulate a push strategy based on the type of trajectory data subscribed by the user, polling frequency, and push method requirements. The push strategy may include data screening rules, push time interval, and push method (such as SMS, email, APP push, etc.). Then, the corresponding push execution unit can push the trajectory data to the user in the specified way according to the formulated push strategy.

[0091] In some embodiments of the present invention, the push strategy includes at least one or more of a trajectory data screening rule, a trajectory data push time interval, and a trajectory data push mode.

[0092] In actual applications, the server can formulate a push strategy based on the type of trajectory data subscribed by the user, polling frequency, and push method requirements. The push strategy may include trajectory data screening rules, trajectory data push time interval, and trajectory data push method (such as SMS, email, APP push, etc.).

[0093] In some embodiments of the present invention, the method further comprises:

[0094] Parsing the trajectory data, and performing a comparison process on the parsed trajectory data according to a preset comparison algorithm to obtain a comparison result;

[0095] The trajectory data is stored in a cache, and in response to the customer's demand for obtaining a comparison result, the comparison result is pushed to the user.

[0096] In the specific implementation, Figure 4 As shown, after receiving the original trajectory data from the IoT device, including location information (longitude, latitude), timestamp, speed, etc., the server can parse the received trajectory data through the trajectory data parsing unit pre-set in the trajectory processing module, extract useful information (such as location information, distance information, etc.), and convert it into a unified data format within the system. And according to the comparison algorithm provided by the user (such as time comparison, location comparison and speed comparison algorithm, etc.), the parsed trajectory data can be processed by the comparison algorithm execution unit. Among them, the comparison algorithm can be customized according to business needs, such as calculating the distance between two points, judging whether two points are in the same area and comparing the speed size. After the comparison algorithm is executed, a comparison result with practical application value can be generated, such as trajectory similarity and abnormal behavior detection.

[0097] Furthermore, the comparison result generation unit pre-set in the cache and database interaction module can store the comparison result in the cache so as to quickly query and respond to the query request of the client. The pre-set cache management unit can also be responsible for maintaining the data in the cache, including operations such as data insertion, updating, and deletion. At the same time, the cache management unit can also monitor the performance indicators such as the cache hit rate and size to ensure the effectiveness and stability of the cache.

[0098] Furthermore, a refresh plan can be formulated according to a preset time interval and data change threshold by a preset refresh strategy formulation unit. When the data in the cache meets the refresh conditions (such as the time interval is reached, the data change exceeds the threshold, etc.), the refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a preset database interaction unit to achieve persistent storage of data. At the same time, the database interaction unit can also record information such as the time and operation type of each data update to facilitate subsequent analysis and optimization of database performance; and when the user queries the comparison result, the target comparison result of the user's query can be determined first and the location of the target comparison result can be determined. For example, the cache can be queried to see whether there is a target comparison result of the user's query and pushed to the user; if the target comparison result is not found in the cache, the target comparison result can be queried from the database and pushed to the user.

[0099] In some embodiments of the present invention, the method further comprises:

[0100] Determine whether the data in the cache meets the refresh condition, and when the data in the cache meets the refresh condition, store the comparison result in the cache in a database.

[0101] In a specific implementation, a refresh plan can be formulated according to a preset time interval and data change threshold through a preset refresh strategy formulation unit. When the data in the cache meets the refresh conditions (such as the time interval is reached, the data change exceeds the threshold, etc.), the refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a preset database interaction unit to achieve persistent storage of data. At the same time, the database interaction unit can also record information such as the time and operation type of each data update to facilitate subsequent analysis and optimization of database performance.

[0102] In some embodiments of the present invention, in response to the customer's demand for obtaining the comparison result, pushing the comparison result to the user includes:

[0103] In response to the comparison result acquisition requirement of the customer, determining a target comparison result corresponding to the comparison result acquisition requirement, and determining a location of the target comparison result;

[0104] According to the location of the target comparison result, the target comparison result is pushed to the user through the cache or the database.

[0105] In actual applications, a refresh plan can be formulated according to a preset time interval and data change threshold through a preset refresh strategy formulation unit. When the data in the cache meets the refresh conditions (such as the time interval is reached, the data change exceeds the threshold, etc.), the refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a preset database interaction unit to achieve persistent storage of data. At the same time, the database interaction unit can also record information such as the time and operation type of each data update to facilitate subsequent analysis and optimization of database performance; and when the user queries the comparison result, the target comparison result of the user's query can be determined first and the location of the target comparison result can be determined. For example, the cache can be queried to see whether there is a target comparison result of the user's query and pushed to the user; if the target comparison result is not found in the cache, the target comparison result can be queried from the database and pushed to the user.

[0106] Based on the above, the trajectory data and comparison results can also be encrypted to ensure the security of the data during transmission and storage. Symmetric encryption algorithms (such as Advanced Encryption Standard, AES) or asymmetric encryption algorithms (such as RSA (Ron Rivest, Adi Shamir, Leonard Adleman algorithm)) can be used to encrypt and decrypt data. Different access rights can be set for different users to ensure that only authorized users can access trajectory data and comparison results. Strategies such as role-based access control (RBAC) or attribute-based access control (ABAC) can also be used to achieve fine-grained permission management.

[0107] Furthermore, sensitive data can be desensitized, such as replacing real location information with fuzzy location information, replacing real names with pseudonyms, etc. Desensitized data can still be used for analysis and comparison, but specific users or location information cannot be directly identified.

[0108] Reference Figure 5 , shows a flowchart of another method for pushing trajectory data provided by some embodiments of the present invention, which may specifically include the following steps:

[0109] Step 501, in response to a track data subscription operation of a user, pushing track data to the user through a polling connection, and recording the polling frequency of the user;

[0110] In the specific implementation, Figure 2 As shown, the embodiment of the present invention can be implemented based on the following system architecture:

[0111] System architecture:

[0112] (1) Client: responsible for user subscription management and push reception.

[0113] (2) Server: includes intelligent push module, trajectory processing module and cache and data security module.

[0114] Intelligent push module: formulate push strategies based on user subscriptions and current system status, and push them to users.

[0115] Trajectory processing module: processes trajectory data according to comparison business requirements and generates comparison results.

[0116] Data security module: encrypt and desensitize data information to ensure the security of user-related information.

[0117] (3) Cache and database interaction module: The comparison results are stored in the cache and refreshed to the database at regular intervals.

[0118] (6) Database: responsible for the persistent storage of data.

[0119] On this basis, the trajectory data from the IoT device can be received through the server and stored in the trajectory data storage table. Then the intelligent push module can formulate a push strategy based on the user subscription status and the current system status, and push the trajectory data to the user according to the push strategy.

[0120] Specifically, the server can create a long polling connection for each user during initialization. This long polling connection can be used to continuously monitor the update of trajectory data. When the client subscribes to trajectory data, it can request data from the server by long polling by default. When there is no new trajectory data update, the server can keep the connection open until new data arrives or the connection times out. The polling frequency of each user can also be recorded, including the time interval and number of requests for each request, for subsequent steps.

[0121] Step 502, determining whether the polling frequency exceeds a preset threshold, and converting the polling connection into a real-time connection when the polling frequency exceeds the preset threshold; wherein the real-time connection is used to push the updated trajectory data to the user immediately when the trajectory data is updated;

[0122] In the specific implementation, Figure 3As shown in the figure, when it is detected that the polling frequency of the user exceeds the preset threshold (such as frequent requests and a short interval between each request), the server can determine that the user needs a more real-time data update. At this time, the server can convert the user's connection from a long polling connection to a long connection (i.e. a real-time connection, such as a WebSocket connection). A long connection allows the server to push data to the client immediately when the data is updated, without the client making frequent requests. After the conversion, the server can maintain a long connection list, monitor the connection status in real time, and ensure that the data can be pushed to the user accurately and promptly. If the user's heartbeat detection fails, the long connection list can remove the user.

[0123] Step 503: determine a push strategy, and push the trajectory data to the user according to the real-time connection and the push strategy.

[0124] In the specific implementation, the server can formulate a push strategy based on the type of trajectory data subscribed by the user, the polling frequency, and the push method requirements. The push strategy may include data screening rules, push time intervals, and push methods (such as SMS, email, APP push, etc.). Then, the corresponding push execution unit can push the trajectory data to the user in the specified manner according to the formulated push strategy. At the same time, the server can record the success or failure of each push for subsequent analysis and optimization of the push strategy.

[0125] Step 504, parsing the trajectory data, and performing a comparison process on the parsed trajectory data according to a preset comparison algorithm to obtain a comparison result;

[0126] In the specific implementation, Figure 4 As shown, after receiving the original trajectory data from the IoT device, including location information (longitude, latitude), timestamp, speed, etc., the server can parse the received trajectory data through the trajectory data parsing unit pre-set in the trajectory processing module, extract useful information (such as location information, distance information, etc.), and convert it into a unified data format within the system. And according to the comparison algorithm provided by the user (such as time comparison, location comparison and speed comparison algorithm, etc.), the parsed trajectory data can be processed by the comparison algorithm execution unit. Among them, the comparison algorithm can be customized according to business needs, such as calculating the distance between two points, judging whether two points are in the same area and comparing the speed size. After the comparison algorithm is executed, a comparison result with practical application value can be generated, such as trajectory similarity and abnormal behavior detection.

[0127] Step 505: store the trajectory data in a cache, and in response to the customer's request for obtaining a comparison result, push the comparison result to the user.

[0128] In actual applications, the comparison result generation unit pre-set in the cache and database interaction module can store the comparison result in the cache to quickly query and respond to the query request of the client. The pre-set cache management unit can also be responsible for maintaining the data in the cache, including operations such as data insertion, update, and deletion. At the same time, the cache management unit can also monitor the cache hit rate, size and other performance indicators to ensure the effectiveness and stability of the cache.

[0129] Furthermore, a refresh plan can be formulated according to a preset time interval and data change threshold by a preset refresh strategy formulation unit. When the data in the cache meets the refresh conditions (such as the time interval is reached, the data change exceeds the threshold, etc.), the refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a preset database interaction unit to achieve persistent storage of data. At the same time, the database interaction unit can also record information such as the time and operation type of each data update to facilitate subsequent analysis and optimization of database performance; and when the user queries the comparison result, the target comparison result of the user's query can be determined first and the location of the target comparison result can be determined. For example, the cache can be queried to see whether there is a target comparison result of the user's query and pushed to the user; if the target comparison result is not found in the cache, the target comparison result can be queried from the database and pushed to the user.

[0130] In general, the above embodiment of the present invention provides a method for pushing trajectory data, which pushes trajectory data to the user through a polling connection and records the user's polling frequency in response to the user's trajectory data subscription operation; then determines whether the polling frequency exceeds the preset threshold, and converts the polling connection into a real-time connection when the polling frequency exceeds the preset threshold; wherein the real-time connection is used to push the updated trajectory data to the user immediately when the trajectory data is updated; and then determines the push strategy, and pushes the trajectory data to the user according to the real-time connection and the push strategy. Adaptive adjustment of the push mode of trajectory data is achieved according to the actual subscription situation and business needs of the user, which improves the real-time nature of trajectory data push, improves user satisfaction and push efficiency, and ensures the response speed and stability of the system. In addition, a comparison result with practical application value is generated by processing the trajectory data according to the comparison business needs. And the response speed and stability of the system are improved by adopting an efficient data storage and query mechanism. The security and privacy of trajectory data and comparison results are also ensured by adopting technical means such as data encryption, access control and data desensitization.
