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 operation efficiency of the server. 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:
in step S110, the main server receives the information of the user terminal.
In one embodiment, the user terminal may be, but is not limited to, various personal computers, notebook computers, smart phones, tablet computers, vehicle-mounted smart devices, portable wearable devices, and the like. In one embodiment, the main server receives the position information and the speed corresponding to each user terminal; and storing the position information and the speed corresponding to the user side in a temporary cache area of the main server. Specifically, a part of the memory in the main server is set as a temporary cache area, and after the main server receives the information sent by the user side, the information is stored in the temporary cache area. The information of the user side includes position information and speed corresponding to the user side. The speed may be a vehicle travel speed. For example, the congestion degree at the current position is reflected by collecting the position information and the vehicle running speed corresponding to the current position. Different ranges of speed correspond to different congestion levels. It is understood that positioning and navigation systems rely on sensors and GPS data to determine the position of a vehicle. In one embodiment, when the vehicle travels on the road, the current coordinate position or the travel track of each vehicle can be acquired through a Global Positioning System (GPS) of the vehicle-mounted device, and the travel speed of each vehicle is calculated and acquired, so as to acquire the position information and the speed of the user terminal.
Step S120, when the received information of the user terminal reaches the preset number, the main server converts the preset number of information into the updated TMC information.
In order to avoid that the main server starts processing once when receiving one piece of information, the preset quantity is set, and when the received user side information reaches the preset quantity, the batch starting processing is unified, so that the batch of information is converted into the updated TMC information. In one embodiment, the predetermined number may be 100 to 2000. In one embodiment, the predetermined number may be 500, 800, 1000, 1500, or 2000.
In one embodiment, the received information is stored in the temporary buffer of the main server before the received information of the user side does not reach the preset amount. When the number of the information reaches a preset number, for example, 1000, the preset number of the information is collectively transferred to the processing area of the main server for processing. After the transfer, the temporary buffer area of the main server is emptied, and then a new batch of information of the user terminals can be received again. In one embodiment, the primary server converts the received preset amount of information in the same transaction to generate updated TMC information. By adopting the design, the conversion efficiency can be improved. Of course, in other embodiments, the main server converts the received preset amount of information separately, i.e. each information is converted separately.
Step S130, the primary server sends the updated TMC information to the corresponding secondary server, so that the secondary server sends the updated TMC information to the user side.
In order to avoid the overload caused by the direct connection of the main server and a plurality of user terminals, in one embodiment, at least one auxiliary server is provided, the main server sends the updated TMC information to the corresponding auxiliary server, and the auxiliary server sends the updated TMC information to the corresponding user terminal.
According to the method for processing the real-time traffic information, after the information of the user side is received by the preset amount, the main server processes the information in a batch mode to convert the received information into the updated TMC information in batches, so that the main server is prevented from being influenced by the information sent by the user side at any moment and frequently starting to process the information, the data processing of the main server is more centralized and efficient, and the resource of the main server is prevented from being occupied at any moment. Meanwhile, the main server sends the updated TMC information to the auxiliary server, and then the auxiliary server sends the updated TMC information to the user side. By the design, a link of the user side, namely the main server, the auxiliary server and the user side is formed, the main server is only responsible for receiving the information of the user side and updating the TMC information, and the auxiliary server shares the task of sending the TMC information, so that the workload of each server is reduced, and the operation efficiency of the system is improved.
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, the main server receives the location information and the speed of the user side, and stores the received location information and the speed of the user side in the temporary buffer area.
In one embodiment, the main server stores all map road data in advance, and after the main server receives the location information of the user terminal, the location information of the user terminal is located in a map road data range stored by the main server. The main server caches the received position information and speed of the user side in a temporary cache region for subsequent batch processing.
In step S220, when the received location information and speed of the user terminal reach the preset number, the main server converts the preset number of information into updated TMC information.
In one embodiment, when the received position information and speed of the user terminal reach a preset number, the preset number of information is converted into SQL statements; and updating the map road data prestored on the main server by using SQL sentences to obtain updated TMC information.
Specifically, Structured Query Language (SQL), which is a database Query and programming Language, is used to access data and Query, update, and manage a relational database system; and is also an extension of the database script file. Structured query languages are high-level, non-procedural programming languages that allow users to work on high-level data structures. The method does not require a user to specify a data storage method and does not require the user to know a specific data storage mode, so that different database systems with completely different underlying structures can use the same structured query language as an interface for data input and management. The structured query language statements can be nested, which allows for great flexibility and powerful functionality. When TMC information corresponding to certain position information is updated, the updating of the TMC information can be realized through an SQL statement command, and the method is convenient to use and high in efficiency.
Further, in order to facilitate storage of map road data and improve reading efficiency, in one embodiment, the master server is provided with a master Redis database. In one embodiment, map road data is stored in a primary Redis database; and executing SQL sentences in the main Redis database, updating the map road data and obtaining updated TMC information. In one embodiment, the primary server stores a predetermined number of SQL statements in the primary Redis database in the same transaction
And executing to obtain the updated TMC information. 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 map road data in Redis database, through caching at Redis, avoid calling the data of server to realize quick reading, reduce simultaneously and occupy the server, thereby reduce the hardware cost. Further, in order to load the SQL statement, the main Redis database is loaded with a redisql module, so that TMC information can be updated through the SQL statement command.
Further, in order to reduce the storage of redundant data and improve the memory utilization efficiency and data processing efficiency of the main server, in one embodiment, the map road data is stored according to preset elements; the preset elements comprise tile numbers, road numbers of all roads, corresponding TMC numbers, traveling directions of the roads, position information of the roads, corresponding TMC frame areas, road condition identifications and latest refreshing time of the road condition identifications. Specifically, in the related art, the electronic map may be simulated and built through a tile map pyramid model. By slicing the electronic map, each layer of map data is sliced into a plurality of tiles. Each tile corresponds to a local section of the layer of map data, and the sections corresponding to the tiles are independent. Each Tile has a corresponding Tile number (Tile id), i.e. the tiles are marked and distinguished by numbers. The TMC bounding box area (bounding box) may be obtained by calculation of 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. Further, in one embodiment, the map road data is pre-stored according to the preset elements, and a TMC table with a specific table structure is formed, so that data interference of other non-preset elements is avoided, redundant data is reduced, and lightweight processing of the map road data in an early storage stage is realized.
Further, in order to update the TMC information stored in the main server according to the received location information and speed of the user side, the specific method is as follows: the position information and the speed of the current vehicle are matched with the TMC table having the above-mentioned preset elements. That is, the position information of the current vehicle is respectively matched with the tile number, the TMC frame area, and the traveling direction of the road. In one embodiment, the location information of the vehicle is first matched to the tile number to determine the approximate geographic range in which the vehicle is located. I.e. from the position information of the vehicle, it can be determined that the vehicle is within the corresponding tile area. The geographical range of the vehicle position information is narrowed through the tile area, the vehicle position information is compared with the TMC frame area in the tile area, and when the vehicle position is located in the TMC frame area, the vehicle is proved to be located on a 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 is represented by the corresponding road number and TMC number. After matching according to the steps, if the position information and the speed of the current vehicle are successfully matched with the map road data stored according to the preset elements in the TMC table, the road on which the vehicle travels can be determined. And then according to the speed of the vehicle, whether the road is congested can be judged, and the road condition identification of the road and the corresponding latest refreshing time can be updated, so that the updated TMC information is obtained.
Step S230, according to the query request of the auxiliary server, the main server sends the updated TMC information to the corresponding auxiliary server; and the auxiliary server carries out a query request according to a preset period.
In one embodiment, the number of secondary servers is at least one. And when the number of the auxiliary servers is multiple, 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, when the number of the auxiliary servers is at least one, each auxiliary server stores the TMC information, and each auxiliary server searches whether the corresponding TMC information needs to be updated. In order to avoid the auxiliary servers from frequently inquiring the main server, each auxiliary server is enabled to send inquiry requests to the main server according to the preset period by setting the preset period, so that the interaction frequency is reduced, and the operation load of the system is reduced. 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, the auxiliary server only needs to search the corresponding map road data in the main database of the main server during query.
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 the 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. The total number of the tiles is 65536 when the tiles are divided by 256 × 256 pixels, for example, and by setting the appropriate number of the auxiliary servers, the map road data corresponding to all the tiles can be distributed, the map data corresponding to each tile can be distributed uniformly on each auxiliary server, and the number of the auxiliary servers can be reduced, so that the hardware cost can be controlled.
In one embodiment, each secondary server has a secondary Redis database, and the map road data in the secondary server can 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. In one embodiment, the primary server sends the updated TMC information to the corresponding secondary server through the log, so that the TMC information of the secondary server is synchronized with the TMC information of the primary server. After the main server receives the query request of the auxiliary server, if the TMC information of the auxiliary server is inconsistent with that of the main server, the main server sends the TMC information to the corresponding auxiliary server in a log mode, so that the sending efficiency is improved, and the auxiliary server can update data conveniently.
In step S240, the auxiliary server sends the updated TMC information to the corresponding user side according to the request of the user side.
When the user terminal needs to inquire the TMC information, the user terminal initiates a request. And the auxiliary server corresponding to the current position information of the user side sends the updated TMC information to the user side. In order to avoid unnecessary data interference on the user side, the user side can send the corresponding TMC information through the auxiliary server after actively requesting the TMC information.
In the method for processing real-time traffic information of this embodiment, the main server receives the position information and the speed of the preset number of the user terminals and stores the position information and the speed to the temporary cache area, and when the preset number is reached, the position information and the speed of the user terminals are converted into SQL statements in a centralized and batch manner. The main server stores road map data in advance according to preset elements through a main Redis database, and executes the converted SQL sentences in the main Redis database, so that the data are updated, updated TMC information is obtained, rapid updating processing of the data is achieved, and updating efficiency of the system is improved. Further, in 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 corresponding TMC information in 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. Meanwhile, the updated TMC information is sent to the user side by the auxiliary server, that is, the main server is responsible for updating the TMC information, and the auxiliary server is responsible for sending the TMC information according to the request of the user side, so that the work operation load of each server is reduced, the overall operation efficiency of the system is improved, the updating and displaying speed of the TMC information of the user side is increased, and the user experience is improved.

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.

Referring to fig. 4, a system 400 for processing real-time traffic information includes a primary server 410 and at least one secondary server 420. Wherein:
the main server is used for receiving the information of the user side; when the received information of the user side reaches the preset number, the main server converts the preset number of information into updated TMC information and sends the updated TMC information to the corresponding auxiliary server;
and the auxiliary server is used for receiving the updated TMC information sent by the main server and sending the updated TMC information to the user side.
Further, the primary Redis database of the primary server 410 and the secondary Redis database of each secondary server 420 pre-store map road data according to the preset elements, respectively. And the main server performs batch processing on the received user side preset information, executes the user side preset information in the main Redis database by using SQL statements, updates the map road data in the main Redis database and obtains the updated TMC information. And the main server sends the updated TMC information to the corresponding auxiliary server in a log mode. And the auxiliary server sends the updated TMC information to the corresponding user side for displaying according to the request of the user side.
In summary, in the real-time traffic information processing system 400 of the present application, the main server 410 and the at least one auxiliary server 420 coordinate to perform work division, so that the main server 410 is responsible for updating, and the auxiliary server 420 is responsible for querying, which avoids concentrating all matters on one main server 410 for processing, thereby reducing the data processing load of a single server and improving the updating efficiency of TMC information. Meanwhile, the main server updates TMC information in batch in the form of SQL sentences and sends the TMC information to the corresponding auxiliary server in the form of logs for synchronization, so that the updating efficiency of data in the system is improved, the latest TMC information can be conveniently and timely sent to the user side, and the user experience is improved.
