The distributed data pushing platform for geomagnetic parking system according to the embodiment of the present invention, as shown in fig. 1, includes: the geomagnetic equipment management module is connected with the geomagnetic data pushing module through a network, and the geomagnetic data pushing module is connected with the service platform.
It can be understood that the geomagnetic device is used for detecting geomagnetic data, specifically detecting whether vehicles exist or not and identifying information such as vehicle types, and the geomagnetic device can be connected with the geomagnetic device management module through an NB-IoT network (Narrow Band Internet of Things, narrow-band internet of things), the NB-IoT is built in a cellular network, only consumes about 180kHz bandwidth, and can be directly deployed in a GSM network, a UMTS network or an LTE network, so that deployment cost is reduced, and smooth upgrading is realized. The service platform is a third party system for parking service operation through geomagnetic data.
In this embodiment, the geomagnetic device management module is configured to receive geomagnetic data sent by geomagnetic devices, generate a corresponding data pushing task according to the geomagnetic data, and send the data pushing task to the geomagnetic data pushing module, where the data pushing task at least includes geomagnetic data to be pushed and a corresponding service platform ID thereof, and a lock competition flag and a completion flag of the data pushing task.
In practical application, the geomagnetic equipment management module needs to be configured correspondingly through a WEB interface, and the method specifically comprises the following steps:
1. the geomagnetic equipment management module is configured with service platform information, wherein the service platform information mainly comprises: service platform ID, service platform name, service platform state, HTTP URL of geomagnetic data received by service platform;
2. configuring a corresponding relation between geomagnetic equipment and a service platform in a geomagnetic equipment management module, wherein the corresponding relation can be represented by equipment numbers of the geomagnetic equipment and service platform IDs;
3. the configuration push server information in the geomagnetic equipment management module mainly comprises the following steps: server name, server ID, server IP, time window corresponding to the server, etc.
In addition, in this embodiment, a plurality of push task groups may be further set, and each push server is divided into corresponding push task groups, where each push task group configures at least two push servers. On the basis, the server information configured in the embodiment also includes the number of the push task group, that is, the push task group ID.
As shown in fig. 2, in this embodiment, a plurality of push task groups may be set, where each push task group configures a plurality of push servers, for example, each push task group configures a first push server and a second push server, where a time window corresponding to the first push server is: starting a starting task every 0 th second of the minute, and executing the task circularly every 2 seconds, wherein the time window corresponding to the second pushing server is as follows: the start-up task starts every 1 st second of minute and is performed in a loop every 2 seconds.
After receiving geomagnetic data sent by geomagnetic equipment, the geomagnetic equipment management module determines a corresponding service platform according to the equipment number of the geomagnetic equipment and generates a data pushing task corresponding to the geomagnetic data. In this embodiment, the data pushing task includes: task number, equipment number of geomagnetic equipment, creation time, service platform ID, geomagnetic data to be pushed, belonging pushing task group, lock competition sign, completion time, feedback information, pushing server ID for completing tasks and the like. Wherein the task number and the creation time are automatically generated by the system; the lock contention flag and the completion flag defaulting to 0, indicating that the data push task is not complete and is not locked by the push server; when the service platform receives geomagnetic data, returning information to the geomagnetic equipment management module, and updating a completion mark, completion time, feedback information and a push server ID of a completion task by the geomagnetic equipment management module according to the returned information; the belonging push task group defaults to be empty, and is added after being distributed by the task management module according to the load state of each push server.

Specifically, after the task management module receives the data pushing tasks, the load state of each pushing server is firstly determined, then the data pushing tasks are uniformly distributed to each pushing task group according to the load state, and the numbers of the corresponding pushing task groups are added in each data pushing task. For example, the task management module receives two data push tasks, and if the system has two push task groups in idle state, the first data push task is allocated to the first push task group, the push task group to which the first data push task belongs is set as the number of the first push task group, the second data push task is allocated to the second push task group, and the push task group to which the second data push task belongs is set as the number of the second push task group, so that the execution efficiency of the data push task is improved.
Each push server queries for tasks within a corresponding time window, e.g., a first push server starts to start a query task at 0 th second per minute and performs a loop every 2 seconds, and a second push server starts to start a query task at 1 st second per minute and performs a loop every 2 seconds. When each pushing server inquires a data pushing task, inquiring a data pushing task with a lock competition sign and a completion sign of 0 in the corresponding task of the pushing task group to which the pushing server belongs, wherein the lock competition sign of 0 indicates that the corresponding data pushing task is not locked by the pushing server, the lock competition sign of 1 indicates that the corresponding data pushing task is already locked by the pushing server, and if the data pushing task with the lock competition sign of 1 is inquired, the task is exited, and the next circulation task is waited for to start; a completion flag of 0 indicates that the corresponding data push task is not completed.
In the process of executing the circulation task each time, if the data pushing task with the query lock competition sign and the completion sign of 0 is queried, firstly modifying the corresponding lock competition sign to 1 to lock the data pushing task so as to avoid lock competition caused by the data pushing task obtained by other data pushing servers at the same time, pushing the corresponding geomagnetic data to the corresponding service platform in an HTTP mode according to the service platform ID, and after the execution is completed, exiting the task to wait for the next circulation task to start.
In this embodiment, after the pushing server pushes geomagnetic data to the service platform, the service platform returns information to the geomagnetic device management module, and after receiving the information returned by the service platform, the geomagnetic device management module updates a completion flag, a pushing server ID, a task completion time and feedback information in a corresponding data pushing task.
In summary, the method of executing tasks based on grouping and time window can greatly reduce the probability of lock contention, so as to improve the pushing efficiency, avoid worrying about a large number of task lock contention caused by acquiring the same task at the same time, further cause the waste of server resources, and improve the pushing efficiency of geomagnetic data.
Based on the above technical solution, the present embodiment further provides a distributed data pushing method for a geomagnetic parking system, where the method is applied to the distributed data pushing platform for a geomagnetic parking system, as shown in fig. 3, and includes the following steps:
