In the related art, for the nationwide TMC system, generally, one server processes TMC information requests from nationwide, millions of TMC information transmissions need to be processed per minute, and the data load is large, which may delay data update of part of the user terminals. In view of the above problems, embodiments of the present application provide a method for processing real-time traffic information, which can reduce a load of a server and improve data update efficiency. The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example one

Fig. 1 is a flowchart illustrating a method for processing real-time traffic information according to an embodiment of the present application.

Referring to fig. 1, the method for processing real-time traffic information includes:

step S110, at least one auxiliary server queries whether the corresponding TMC information needs to be updated.

In one embodiment, the auxiliary server is configured to receive the location information of the user side, and send the corresponding TMC information to the user side according to the location information, so that the user can view the latest real-time traffic road condition information. In order to ensure that the TMC information obtained by the user is as new as possible, it can be determined whether the TMC information needs to be updated by querying the TMC information of the secondary server. Further, the number of secondary servers may be one or more than one. When the number of the auxiliary servers is at least one, each auxiliary server stores TMC information, and each auxiliary server searches whether the corresponding TMC information needs to be updated or not.

Step S120, if the TMC information of the auxiliary server needs to be updated, an update request is sent to the main server.

When the TMC information of the auxiliary server needs to be updated, the updating request is sent to the main server, so that the main server can perform corresponding updating actions subsequently. Further, when the number of the auxiliary servers is more than one, the updating requirements of each auxiliary server are different, namely when a part of auxiliary servers needing to update TMC information exist, corresponding updating requests are sent to the main server; and the rest auxiliary servers which do not need to be updated are kept unchanged.

Step S130, receiving TMC information which is sent by the main server and updated according to the update request.

Specifically, the main server sends the latest TMC information stored on the main server to the auxiliary server as the TMC information that needs to be updated by the auxiliary server according to the update request of the auxiliary server, and the auxiliary server receives the corresponding TMC information and replaces the original TMC information in the auxiliary server, so that the TMC information on the auxiliary server is kept in a relatively latest state. In order to ensure that the TMC information stored in the main server is kept up to date, the main server receives the position information and the vehicle speed of the user side in real time, and automatically updates the stored TMC information according to the corresponding position information and the vehicle speed, so that the TMC information sent to the auxiliary server by the main server is ensured to be the latest TMC information.

In the method for processing the real-time traffic information, the at least one auxiliary server respectively inquires whether the TMC information needs to be updated, the main server respectively updates the auxiliary servers needing to be updated according to the updating request, and the corresponding auxiliary servers receive the updated TMC information to complete the updating. According to the technical scheme, the query step and the update step are distributed on the main server and the auxiliary server to be correspondingly carried out, namely the auxiliary server is responsible for querying, the main server is responsible for updating, various tasks are prevented from being processed on one server in a centralized mode, and therefore the main server and the auxiliary server cooperate with each other to improve the updating efficiency of TMC information while the data processing load of a single server is reduced.

Example two

To further describe the processing method of the real-time traffic information of the present application, referring to fig. 2, the processing method of the real-time traffic information includes:

step S210, pre-storing map road data in each of the auxiliary server and the main server.

In one embodiment, the main server stores all the map road data uniformly; and each auxiliary server stores the corresponding map road number according to the map area. That is, each secondary server only stores different parts of all the map road data, and the set of all the map road data stored by each secondary server is all the map road data stored on the primary server. Further, in order to facilitate the distribution and storage of map road data, in one specific embodiment, a corresponding number of secondary servers are set according to the number of map tiles; and dividing the map road data according to map tiles, and distributing and storing the divided map road data to the corresponding auxiliary server.

In the related art, the electronic map can be simulated and built through a tile map pyramid model. Specifically, the tile map pyramid model is a multi-resolution hierarchical model, and the resolution is lower and lower from the bottom layer to the top layer of the tile pyramid, but the represented geographic range is unchanged. Firstly, determining the number N of zoom levels to be provided by a map service platform, taking a map picture with the highest zoom level and the largest map scale as the bottom layer of a pyramid, namely a layer 0, partitioning the map picture, cutting the map picture from the left upper corner of the map picture to the right and from the top to the bottom, and dividing the map picture into square map tiles with the same size (such as 256 multiplied by 256 pixels) to form a layer 0 tile matrix; on the basis of the map picture of the 0 th layer, generating the map picture of the 1 st layer by a method of synthesizing one pixel by every 2 multiplied by 2 pixels, partitioning the map picture, and dividing the map picture into square map tiles with the same size as the next layer to form a tile matrix of the 1 st layer; generating a layer 2 tile matrix by the same method; …, respectively; this continues until layer N-1, which forms the entire tile pyramid.

It is understood that the map road data is a part of the map data. In the application, the storage of redundant data can be reduced and the memory can be saved only by storing the tile layer where the map road data are located. In order to uniformly distribute and store the map road data in each auxiliary server, in one specific embodiment, the number of the map road data to be distributed is calculated and obtained according to the number of map tiles and the number of the auxiliary servers; and distributing and storing each piece of map road data in a corresponding auxiliary server. In one embodiment, the number of copies of the map road data to be distributed is calculated by dividing the number of map tiles by the number of secondary servers. In one embodiment, the number of secondary servers may be a multiple of 4 but is not limited to such. In one embodiment, the number of secondary servers may be 4, 16, 64, etc. Such a number, when the tiles are divided by, for example, 256 × 256 pixels, is 65536 tiles in total, and by setting the appropriate number of secondary servers, ensures that the map road data corresponding to all the tiles is distributed, and facilitates the uniform distribution of the map data corresponding to each tile on each secondary server. Meanwhile, the number of auxiliary servers is reduced, and the hardware cost is controlled.

In one embodiment, the map road data is stored according to preset elements such as tile numbers, road numbers of each road and corresponding TMC numbers, traveling directions of the roads, position information of the roads and corresponding TMC frame areas, road condition identifications and latest refreshing time of the road condition identifications. Wherein, the TMC bounding box (bounding box) may be obtained by calculating the location information of the road. Each TMC frame area belongs to the corresponding tile, that is, the tile area covers the TMC frame area, and the TMC frame area is the area covering the corresponding road. The location information of each road may specifically specify the location of the road on the electronic map. In order to further distinguish each Road, marking may be performed by a unique Road number (Road id) of each Road and a unique TMC number (TMC id) corresponding to the Road. Meanwhile, for a bidirectional road or a unidirectional road, a traveling direction (Heading) of each road needs to be specified. The traffic condition Flag (TMC Flag) is used to identify whether traffic is congested or not. The latest Update time (Update time) is updated according to the state of whether the traffic is congested or not, namely, the Update is performed according to the Update of the road condition identification, so that the real-time traffic information of the corresponding road can be reflected in real time, namely, whether the road is congested at the latest Update time.

In one specific embodiment, the map road data is respectively stored in the main server and the auxiliary server according to the preset elements, so that the map road data can be quickly read, redundant data can be eliminated, and the data storage capacity can be reduced. In order to ensure that the TMC information corresponding to the map road data in the main server is in the latest state, the main server may update in real time according to the user vehicle location information according to the preset elements. Specifically, the GPS coordinate information of the vehicle is first matched to the tile number, determining the approximate geographic range of the vehicle. I.e. from the position information of the vehicle, it can be determined that the vehicle is within the corresponding tile area. And reducing the geographical range of the vehicle position information through the tile areas. And comparing the position information of the vehicle with the TMC frame area in the tile area, and when the position of the vehicle is located in the TMC frame area, proving that the vehicle is located on the corresponding road in the TMC frame area. In order to distinguish the bidirectional lanes, the road on which the vehicle is located is finally determined according to the traveling direction of the road, and the road is represented by the corresponding road number and TMC number, that is, the corresponding road on which the current vehicle is located is confirmed. And then according to the speed of the vehicle, whether the road is congested can be confirmed, so that real-time traffic information of the corresponding road is obtained.

Step S220, each of the auxiliary servers queries, according to a preset period, whether the TMC information corresponding to the map road data is the same as the TMC information of the map road data corresponding to the main server.

In one specific implementation, each secondary server queries a primary Redis database of the primary server according to a preset period. Because each auxiliary server only stores a small part of map road data in all map road data, and the main server stores all map road data, during query, the auxiliary server only needs to search the corresponding map road data in the main Redis database of the main server. By setting the preset period of inquiry, frequent interaction between the auxiliary server and the main server is avoided, and respective operation load is reduced.

In one specific embodiment, the master server is provided with a master Redis database, and the TMC information of the master server is stored in the master Redis database according to preset elements; and/or each auxiliary server is provided with a corresponding auxiliary Redis database, and TMC information of the auxiliary server is stored in the auxiliary Redis database according to the preset elements. Specifically, a Remote directory Server (Remote directory Server) is an in-memory cache database, which is written in C language, and the data model is key-value. Redis is widely used because it can support rich data types, such as String, List, Hash, Set, Sorted Set, etc. Through saving TMC information in Redis database, through caching at Redis, avoid calling the local data of main server and auxiliary server to realize quick reading, reduce the memory that occupies the server simultaneously, thereby reduce the hardware cost.

Further, the map road data can be stored in a main Redis database of the main server according to the preset elements, so that the reading speed is further increased. In one embodiment, the map road data in the secondary server may also be stored according to the preset elements. In one embodiment, the map road data in the secondary server may also be stored in the secondary Redis database according to the preset elements. By the design, the storage mode of each auxiliary server corresponds to that of the main server, so that quick query and update are facilitated.

Step S230, if the TMC information in the secondary server is different from the corresponding TMC information in the primary server, determining that the TMC information in the secondary server needs to be updated, and sending an update request to the primary server corresponding to the secondary server that needs to update the TMC information.

It can be understood that, since the number of the secondary servers is at least one, the TMC information of each secondary server queried in each preset period is not the same as the corresponding TMC information in the primary server. And when the TMC information corresponding to the map road data stored in the auxiliary server is different from the TMC information corresponding to the map road data in the main server, the auxiliary server sends an updating request to the main server. It is to be understood that, if the TMC information corresponding to the map road data in the secondary server is the same as the TMC information corresponding to the map road data in the primary server through the query, and there is no need to update the data, step S240 is directly performed.

Step S240, the corresponding auxiliary server receives the TMC information which is sent by the main server and updated according to the update request.

In one embodiment, the main server may send the updated TMC information to the auxiliary server according to the preset elements to replace the original TMC information in the auxiliary server, so that the server may send the latest TMC information to the user side, and ensure that the user obtains the latest real-time traffic information.

In other embodiments, after the auxiliary server updates the TMC information, the auxiliary server may send the latest TMC information to the user side according to a request of the user side. Or, if the TMC information of the secondary server does not need to be updated, the secondary server sends the original TMC information to the user side.

In the method for processing real-time traffic information of this embodiment, the same map road data is stored in the main server and each auxiliary server, and whether the TMC information of each auxiliary server is the same as the TMC information corresponding to the main server is periodically queried. When the TMC information stored in the auxiliary server is different, the auxiliary server is updated through the main server, and the data of the auxiliary server is ensured to be kept in the latest state. Meanwhile, the main server and the auxiliary server both adopt Redis databases for data storage, so that the data reading and updating efficiency is improved. In addition, the number of the auxiliary servers is set according to the quota of the number of the map tiles, so that the map road data are distributed on each auxiliary server to be stored in a balanced mode. Each auxiliary server only needs to periodically inquire whether the TMC information of the auxiliary server is the same as that of the main server or not, and then the main server updates the data of each auxiliary server to take the best role, so that the overload of the load on a single server is avoided, and the overall operation efficiency of the system is not influenced.

Corresponding to the embodiment of the application function implementation method, the application also provides a device and a system for processing real-time traffic information and a corresponding embodiment. Specifically, the apparatus described in this embodiment of the present application may implement part or all of the processes in the embodiment of the method for processing real-time traffic information described in this application in conjunction with fig. 1-2.

If the TMC information in the secondary server is different from the corresponding TMC information in the primary server, the request sending module 330 sends an update request to the primary server. Finally, the information receiving module 340 receives the latest TMC information in the primary server to replace the corresponding original TMC information in the secondary server.

According to the device for processing the real-time traffic information, whether the corresponding TMC information needs to be updated or not is respectively inquired for at least one auxiliary server through the inquiry module 320, when the TMC information needs to be updated, the request sending module 330 sends the update information to the main server, and then the main server respectively updates the auxiliary servers needing to be updated through the update sending module 340. The query step and the update step are performed in a dispersed manner, so that processing on one main server is avoided, the data processing load of a single server is reduced, and the update efficiency of TMC information is improved.

Further, the main server 410 and each of the sub servers 420 previously store map road data, respectively. Specifically, the main server 410 stores all the map road data in a unified manner; and each auxiliary server stores the corresponding map road data according to the map area. Further, to evenly distribute the amount of data storage, in one embodiment, a corresponding number of secondary servers 420 are set according to the number of map tiles; and dividing the map road data according to the map tiles, and distributing and storing the divided map road data to the corresponding auxiliary server 420.
