A method and apparatus for pushing trajectory data, an electronic device, and a storage medium.

Abstract

This invention provides a trajectory data push method, apparatus, electronic device, and storage medium. Responding to a user's trajectory data subscription operation, the method pushes trajectory data to the user via a polling connection and records the user's polling frequency. It then determines whether the polling frequency exceeds a preset threshold, and if so, converts the polling connection to a real-time connection. The real-time connection ensures that updated trajectory data is immediately pushed to the user when updated. A push strategy is then determined, and the trajectory data is pushed to the user according to the real-time connection and the push strategy. This allows for adaptive adjustment of the trajectory data push method based on the user's actual subscription status and business needs, improving the real-time performance of trajectory data push, increasing user satisfaction and push efficiency, and ensuring system response speed and stability.

[0057] For ease of explanation, the following will provide explanations of the relevant terms used in the embodiments of the present invention:

[0058] Track data refers to data collected by Internet of Things (IoT) devices (such as GPS (Global Positioning System) locators, mobile phones, etc.) that includes location information (longitude, latitude), timestamps, speed, and other information.

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

[0060] Comparison Algorithm: Processes trajectory data to generate comparison results with practical application value.

[0061] Algorithms such as trajectory similarity and abnormal behavior detection.

[0062] Cache and database interaction: The process of storing 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 Internet of Things (IoT) devices (such as GPS locators, mobile phones, etc.) that includes location information (longitude, latitude), timestamps, speed, and other information.

[0064] With the rapid development of IoT, big data and cloud computing technologies, the collection, processing and delivery of trajectory data has become a key requirement in many application scenarios.

[0065] However, trajectory data processing systems in related technologies often lack intelligence, failing to flexibly adjust push strategies based on user subscriptions and business needs; and their query efficiency is low, failing to meet users' real-time requirements for trajectory data push.

[0066] To address the aforementioned problems, this invention, based on the core technical concept of adaptively adjusting the trajectory data push method according to the user's actual subscription status and business needs, improves upon the trajectory data push method in related technologies. The invention will be described in detail below with reference to the accompanying drawings:

[0067] Reference Figure 1 The diagram illustrates a flowchart of a trajectory data push method according to some embodiments of the present invention, which may specifically include the following steps:

[0068] Step 101: In response to the user's trajectory data subscription operation, push trajectory data to the user through a polling connection and record the user's polling frequency;

[0069] In specific implementations, such as Figure 2 As shown, embodiments 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 notification reception.

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

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

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

[0075] Data security module: Encrypts and de-identifies data information to ensure the security of user-related information.

[0076] (3) Cache and database interaction module: Store the comparison results in the cache and refresh them to the database periodically.

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

[0078] Based on this, the server can receive trajectory data from IoT devices and store it in the trajectory data storage table. Then, the smart push module can formulate a push strategy based on the user's 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 for updates to trajectory data. When a client subscribes to trajectory data, it can request data from the server via long-polling by default. The server can keep the connection open until new data arrives or the connection times out, provided there are no new trajectory data updates. It can also record the polling frequency for each user, including the time interval between each request and the number of requests, for use in subsequent steps.

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

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

[0082] In practical applications, the server can create a long-polling connection for each user during initialization. This long-polling connection can be used to continuously monitor for updates to trajectory data. When subscribing to trajectory data, clients can, by default, request data from the server using long-polling. The server can keep the connection open until new data arrives or the connection times out, provided there are no new trajectory data updates.

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

[0084] In specific implementations, such as Figure 3As shown, when the server detects that a user's polling frequency exceeds a preset threshold (e.g., frequent requests with short intervals between requests), it can determine that the user needs more real-time data updates. In this case, 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). Long connections allow the server to push data to the client immediately upon data updates, without requiring the client to frequently initiate requests. After the conversion, the server can maintain a long connection list, monitoring the connection status in real time to ensure that data is pushed to the user accurately and promptly. If a user's heartbeat fails, the user can be removed from the long connection list.

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

[0086] In practical implementation, the server can formulate a push strategy based on information such as the type of trajectory data subscribed to by the user, the polling frequency, and the push method requirements. The push strategy can include data filtering rules, push 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. Simultaneously, 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 user's polling frequency information, push method requirements information, and the trajectory data type information subscribed to by the user;

[0089] The push strategy is determined based on one or more of the polling frequency information, push method requirement information, and the user's subscribed trajectory data type information.

[0090] In practical applications, the server can formulate a push strategy based on information such as the type of trajectory data subscribed to by the user, the polling frequency, and the push method requirements. The push strategy can include data filtering rules, push intervals, and push methods (such as SMS, email, and app push). Subsequently, the corresponding push execution unit can push the trajectory data to the user in the specified manner according to the formulated push strategy.

[0091] In some embodiments of the present invention, the push strategy includes at least one or more of trajectory data filtering rules, trajectory data push time intervals, and trajectory data push methods.

[0092] In practical applications, servers can formulate push strategies based on information such as the type of trajectory data subscribed by users, polling frequency, and push method requirements. Push strategies can include trajectory data filtering rules, trajectory data push intervals, and trajectory data push methods (such as SMS, email, APP push, etc.).

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

[0094] The trajectory data is parsed, and the parsed trajectory data is compared according to a preset comparison algorithm to obtain the comparison result;

[0095] The trajectory data is stored in a cache, and in response to the customer's request to obtain the comparison results, the comparison results are pushed to the user.

[0096] In specific implementations, such as Figure 4 As shown, after receiving raw trajectory data from IoT devices, including location information (longitude, latitude), timestamps, and speed, the server can parse the received trajectory data through a pre-set trajectory data parsing unit in the trajectory processing module, extracting useful information (such as location information, distance information, etc.) and converting it into a unified data format within the system. It can also process the parsed trajectory data through a comparison algorithm execution unit based on user-provided comparison algorithms (such as time comparison, location comparison, and speed comparison algorithms). The comparison algorithms can be customized according to business needs, such as calculating the distance between two points, determining whether two points are in the same area, and comparing speeds. After the comparison algorithm is executed, comparison results with practical application value can be generated, such as trajectory similarity and abnormal behavior detection.

[0097] Furthermore, the comparison results can be stored in the cache through a pre-configured comparison result generation unit in the cache and database interaction module, enabling rapid querying and response to client query requests. A pre-configured cache management unit can also be responsible for maintaining the data in the cache, including data insertion, updating, and deletion operations. Simultaneously, the cache management unit can monitor performance metrics such as cache hit rate and size to ensure the effectiveness and stability of the cache.

[0098] Furthermore, a refresh plan can be formulated by a pre-set refresh strategy formulation unit based on preset time intervals and data change thresholds. When the data in the cache meets the refresh conditions (such as the time interval being reached, or the data change exceeding the threshold), a refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a pre-set database interaction unit, achieving persistent data storage. Simultaneously, the database interaction unit can record information such as the time and operation type of each data update for subsequent analysis and optimization of database performance. When a user queries the comparison results, the target comparison result can be determined first, along with its location. For example, the cache can be checked to see if the target comparison result exists, and then pushed to the user. If the target comparison result is not found in the cache, it can be retrieved from the database and pushed to the user.

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

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

[0101] In practical implementation, a pre-defined refresh strategy formulation unit can formulate a refresh plan based on preset time intervals and data change thresholds. When the data in the cache meets the refresh conditions (such as the time interval being reached or the data change exceeding the threshold), a refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a pre-defined database interaction unit, achieving persistent data storage. Simultaneously, the database interaction unit can also record information such as the time and operation type of each data update for subsequent analysis and optimization of database performance.

[0102] In some embodiments of the present invention, the step of pushing the comparison results to the user in response to the customer's request for comparison results includes:

[0103] In response to the customer's request to obtain comparison results, determine the target comparison result corresponding to the request, and determine the location of the target comparison result;

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

[0105] In practical applications, a refresh plan can be formulated by a pre-set refresh strategy formulation unit based on preset time intervals and data change thresholds. When the data in the cache meets the refresh conditions (such as the time interval being reached, or the data change exceeding the threshold), a refresh operation can be triggered. This means that the comparison results in the cache can be updated to the database through a pre-set database interaction unit, achieving persistent data storage. Simultaneously, the database interaction unit can record information such as the time and operation type of each data update for subsequent analysis and optimization of database performance. When a user queries the comparison results, the target comparison result can be determined first, along with its location. For example, the cache can be checked to see if the target comparison result exists, and then pushed to the user. If the target comparison result is not found in the cache, it can be retrieved from the database and pushed to the user.

[0106] Building upon the above, trajectory data and comparison results can be encrypted to ensure data security 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 for encryption and decryption. Different access permissions can be set for different users, ensuring that only authorized users can access trajectory data and comparison results. Furthermore, role-based access control (RBAC) or attribute-based access control (ABAC) strategies can be employed to achieve fine-grained access control.

[0107] Furthermore, sensitive data can be anonymized, such as replacing real location information with ambiguous location information or real names with pseudonyms. The anonymized data can still be used for analysis and comparison, but it cannot directly identify specific users or location information.

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

[0109] Step 501: In response to the user's trajectory data subscription operation, push trajectory data to the user through a polling connection and record the user's polling frequency;

[0110] In specific implementations, such as Figure 2 As shown, embodiments 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 notification reception.

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

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

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

[0116] Data security module: Encrypts and de-identifies data information to ensure the security of user-related information.

[0117] (3) Cache and database interaction module: Store the comparison results in the cache and refresh them to the database periodically.

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

[0119] Based on this, the server can receive trajectory data from IoT devices and store it in the trajectory data storage table. Then, the smart push module can formulate a push strategy based on the user's 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 for updates to trajectory data. When a client subscribes to trajectory data, it can request data from the server via long-polling by default. The server can keep the connection open until new data arrives or the connection times out, provided there are no new trajectory data updates. It can also record the polling frequency for each user, including the time interval between each request and the number of requests, for use in subsequent steps.

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

[0122] In specific implementations, such as Figure 3As shown, when the server detects that a user's polling frequency exceeds a preset threshold (e.g., frequent requests with short intervals between requests), it can determine that the user needs more real-time data updates. In this case, 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). Long connections allow the server to push data to the client immediately upon data updates, without requiring the client to frequently initiate requests. After the conversion, the server can maintain a long connection list, monitoring the connection status in real time to ensure that data is pushed to the user accurately and promptly. If a user's heartbeat fails, the user can be removed from the long connection list.

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

[0124] In practical implementation, the server can formulate a push strategy based on information such as the type of trajectory data subscribed to by the user, the polling frequency, and the push method requirements. The push strategy can include data filtering rules, push 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. Simultaneously, the server can record the success or failure of each push for subsequent analysis and optimization of the push strategy.

[0125] Step 504: parse the trajectory data and perform comparison processing on the parsed trajectory data according to a preset comparison algorithm to obtain the comparison result;

[0126] In specific implementations, such as Figure 4 As shown, after receiving raw trajectory data from IoT devices, including location information (longitude, latitude), timestamps, and speed, the server can parse the received trajectory data through a pre-set trajectory data parsing unit in the trajectory processing module, extracting useful information (such as location information, distance information, etc.) and converting it into a unified data format within the system. It can also process the parsed trajectory data through a comparison algorithm execution unit based on user-provided comparison algorithms (such as time comparison, location comparison, and speed comparison algorithms). The comparison algorithms can be customized according to business needs, such as calculating the distance between two points, determining whether two points are in the same area, and comparing speeds. After the comparison algorithm is executed, comparison results 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 push the comparison results to the user in response to the customer's request for comparison results.

[0128] In practical applications, comparison results can be stored in the cache through a pre-configured comparison result generation unit within the cache and database interaction module, enabling rapid querying and response to client query requests. A pre-configured cache management unit can also be responsible for maintaining the data in the cache, including operations such as data insertion, updating, and deletion. Simultaneously, the cache management unit can monitor performance metrics such as cache hit rate and size to ensure the effectiveness and stability of the cache.

[0129] Furthermore, a refresh plan can be formulated by a pre-set refresh strategy formulation unit based on preset time intervals and data change thresholds. When the data in the cache meets the refresh conditions (such as the time interval being reached, or the data change exceeding the threshold), a refresh operation can be triggered. That is, the comparison results in the cache can be updated to the database through a pre-set database interaction unit, achieving persistent data storage. Simultaneously, the database interaction unit can record information such as the time and operation type of each data update for subsequent analysis and optimization of database performance. When a user queries the comparison results, the target comparison result can be determined first, along with its location. For example, the cache can be checked to see if the target comparison result exists, and then pushed to the user. If the target comparison result is not found in the cache, it can be retrieved from the database and pushed to the user.

[0130] In summary, the trajectory data push method provided by the above embodiments of the present invention, in response to a user's trajectory data subscription operation, pushes trajectory data to the user through a polling connection and records the user's polling frequency; then it determines whether the polling frequency exceeds a preset threshold, and if the polling frequency exceeds the preset threshold, it converts the polling connection into a real-time connection; wherein, the real-time connection is used to immediately push the updated trajectory data to the user when the trajectory data is updated; then, a push strategy is determined, and the trajectory data is pushed to the user according to the real-time connection and the push strategy. This achieves adaptive adjustment of the trajectory data push method according to the user's actual subscription status and business needs, improving the real-time performance of trajectory data push, increasing user satisfaction and push efficiency, and ensuring the system's response speed and stability. Furthermore, it generates comparison results with practical application value by processing the trajectory data according to comparison business needs. It also improves the system's response speed and stability by adopting an efficient data storage and query mechanism. Finally, it ensures the security and privacy of trajectory data and comparison results by employing data encryption, access control, and data anonymization technologies.
