In the related art, the car navigation can provide services such as positioning and navigation for a user. Because the map data in the vehicle-mounted navigation is not updated in real time, the user cannot timely and accurately acquire the latest map data, and the accuracy of the navigation is affected. In order to solve the above problems, embodiments of the present application provide a method for processing data of a vehicle-mounted intelligent device, which can update map data in time and ensure timeliness and accuracy of the data. 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 schematic flowchart of a method for processing vehicle-mounted smart device data according to an embodiment of the present application.
Referring to fig. 1, the present application provides a method for processing data of a vehicle-mounted intelligent device, including:
step S110, receiving a request containing the position information of the vehicle-mounted intelligent device.
The vehicle-mounted intelligent device is one of the user terminals. In one embodiment, the in-vehicle smart device may be an in-vehicle navigation. In other embodiments, the user end may be, but is not limited to, various personal computers, laptops, smartphones, tablets, and portable wearable devices. The position information of this application can derive from other multiple user terminals promptly, not only is limited to on-vehicle smart machine. Further, the location information may be real-time location information where the user is currently located, or location information corresponding to the location. In one embodiment, the location information may be geographic coordinates, and may be obtained by GPS (Global Positioning System) Positioning.
And step S120, according to the position information in the request, searching whether a cache region of the server stores map data corresponding to the position information or not, wherein the map data is stored in the cache region according to a preset module.
The cache area refers to a storage capable of high-speed data exchange, and exchanges data with a CPU (central processing unit) of the server before the memory, so that the speed is high. By establishing a cache region in the server and storing map data in the cache region in advance, the searching efficiency is improved.
In one embodiment, the storing the map data in the buffer according to a preset module includes: according to the marks and the version numbers of the map tiles, the map data of each map tile are respectively formed into corresponding file data according to a preset module and stored in a Redis database; the preset module at least includes one of a BMD (basic map display) module, a route module, a POI (Point of Information) module, and a name module.
Specifically, in the related art, the electronic map may be simulated and built through a tile map pyramid model. 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 geographical range is unchanged. Specifically, the number N of zoom levels to be provided by the map service platform is determined, the map picture with the highest zoom level and the largest map scale is used as the bottom layer of the pyramid, namely the 0 th layer, and is partitioned, the map picture is cut from the left upper corner of the map picture, from the left to the right, from the top to the bottom, and is divided into square map tiles with the same size (for example, 256 × 256 pixels), so that a tile matrix of the 0 th layer is formed. On the basis of the map picture of the layer 0, generating the map picture of the layer 1 by a method of synthesizing one pixel by every 2x2 pixels, partitioning the map picture of the layer 1, and dividing the map picture into square map tiles with the same size as the next layer to form a tile matrix of the layer 1; the same method is used to generate the layer 2 tile matrix. This continues until layer N-1, which forms the entire tile pyramid.
Further, each map tile has a corresponding flag and version number. Specifically, when sliced, to facilitate distinguishing each map tile (tile), each map tile has a corresponding flag, which may be represented by an ID number, so that each map tile is distinguished. Meanwhile, since the map data is updated according to changes in the ground environment and the like, in order to distinguish the updated map data each time, each updated electronic map may be marked with a version number. Accordingly, each map tile of the updated electronic map has a corresponding version number.
The map data can be classified according to preset modules such as BMD, route, POI and name, and is stored in a Redis database in a cache region of the server. Further, with each map tile as a unit, storing the map data according to the preset module to form a plurality of file data and storing the file data in a Redis database. That is, each map tile stores file data corresponding to at least one preset module. For example, a tile has both route data and BMD data on it. It can be understood that obtaining the corresponding map data in the location information is obtaining the file data of each preset module on the tile. One of the document data may be at least one of BMD data, route data, POI data, or name data corresponding to one of the map tiles. In order to distinguish the file data, each file data is recorded with a flag and a version number of the corresponding map tile. When the corresponding map data is searched, a plurality of corresponding file data are searched, and the plurality of file data form the required map data. By classifying and storing the map data according to the preset modules, the data can be conveniently and quickly searched and obtained, so that the searching efficiency is improved.
Further, 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. The Redis database is arranged in the cache region of the server, so that the data of the hard disk of the server is prevented from being called, rapid reading is realized, meanwhile, the resource occupation of the server is reduced, and the operating efficiency of the server is improved.
And step S130, if the corresponding map data stored according to the preset module is stored in the cache area of the server, sending the map data to the vehicle-mounted intelligent equipment for displaying.
It can be understood that, when searching for corresponding map data, in order to reduce and improve the search efficiency, the cache region is preferentially searched and the map data corresponding to the cache region is acquired. And if the corresponding map data are stored in the cache region, acquiring the corresponding map data to the vehicle-mounted intelligent equipment, and displaying the corresponding map data on the vehicle-mounted intelligent equipment.
In summary, in the data processing method for the vehicle-mounted intelligent device, the server receives the current position information of the vehicle-mounted intelligent device, and then searches for corresponding map data in the cache region according to the position information in a targeted manner, wherein the map data are stored according to a preset module; and when the map data are found to be stored, displaying the map data on the vehicle-mounted intelligent equipment. By means of the design, on one hand, the stored corresponding map data are searched in a cache region of the server in a targeted mode, the searching efficiency can be improved, the display speed is improved, and the map data of the server are updated more timely compared with the data of the vehicle-mounted intelligent device, so that the accuracy of the displayed map data is guaranteed; simultaneously, the resource occupation of the server hard disk is reduced, so that the operation load of the server is reduced; on the other hand, the map data are stored in a classified mode according to the preset modules, so that the data are convenient to search and obtain quickly, and the display efficiency is further improved.
Example two
Referring to fig. 2, an embodiment of the present application further provides a method for processing data of a vehicle-mounted intelligent device. The processing method of the vehicle-mounted intelligent device data at least comprises the following steps:
step S210, receiving a request containing the position information of the vehicle-mounted intelligent device.
In one embodiment, the location information may be geographic coordinates, i.e., latitude and longitude coordinates. The geographic coordinates can be obtained by positioning modes such as GPS, Wi-Fi or a base station.
Step S220, according to the position information, whether a Redis database of a cache region of the server stores corresponding map data stored according to a preset module is searched; and if the Redis database stores the corresponding map data, sending the map data to the vehicle-mounted intelligent equipment for displaying.
It can be understood that the server caches the map data by using the Reids database, and the searching efficiency can be improved. In one specific embodiment, the map data is classified and stored in a Redis database of the cache region according to the marks and the version numbers of the map tiles and according to the BMD module, the route module, the POI module and the name module. On one hand, the design realizes refined classification and is convenient for quick identification, thereby further improving the searching efficiency. On the other hand, the map tiles are obtained by slicing the layers of the electronic map, and can quickly correspond to the position information through the marks of the map tiles; meanwhile, the version number of the current map data can be determined through the version number of the map tile, so that the updating condition of the map data can be conveniently known. In the embodiment, the data condition is confirmed by preferentially searching the Redis database, so that the searching efficiency is improved. And if the Redis database stores the corresponding map data, sending the corresponding map data to the vehicle-mounted intelligent equipment for displaying.
Step S230, if the Redis database does not store the corresponding map data, searching whether a hard disk of the server stores the corresponding map data or not; and if the hard disk stores the corresponding map data, sending the corresponding map data to the vehicle-mounted intelligent equipment for display.
It can be understood that the data in the cache area is only a duplicate of partial data in the hard disk, so that the in-vehicle intelligent device may find the data in the cache area of the server without finding the data (because the data is not copied from the hard disk into the cache area), and the data needs to be found in the hard disk of the server. In other embodiments, a Redis database may also be disposed in the hard disk, and the map data is stored by the Redis database.
Further, in order to determine the update state of the map data in the hard disk, in one embodiment, the latest version number of the corresponding map data is searched through a network terminal, and the existing version number of the map data of the hard disk is compared with the latest version number; if the current version number is the same as the latest version number, displaying map data on the vehicle-mounted intelligent equipment; and if the existing version number is different from the latest version number, downloading the map data with the latest version number through the network terminal, and replacing the map data with the existing version number on the hard disk. It can be understood that the version of the electronic map is marked by a version number, and the version number of the electronic map is the version number of each map tile and is also the version number of each file data in each preset module in the Redis database.
Generally, the electronic map on the network side has the latest version and then the latest version number. The existing version number of the electronic map of the hard disk of the server is the version number of the map data stored currently. The updating state of the map data currently stored in the hard disk can be determined by comparing the current version number of the map data currently stored in the hard disk with the latest version number of the map data at the network end. If the existing version number is the same as the latest version number, the map data currently stored in the hard disk is the latest version number; if the two are different, the map data currently stored in the hard disk is a lagging version and needs to be updated. The map data with the latest version number is downloaded through the network terminal and replaced by the map data with the existing version number on the hard disk, so that the map data on the hard disk is changed into the data with the latest version number, and the latest map data is sent to the vehicle-mounted intelligent device to be displayed.
In other embodiments, if there is no network, the version number cannot be searched through the network side, and the map data cannot be downloaded through the network side. At the moment, if the map data corresponding to the position information is stored in the hard disk, the map data with the existing version number on the hard disk is directly sent to the vehicle-mounted intelligent device to be displayed.
And step S240, if the corresponding map data is not stored in the hard disk, downloading the map data with the latest version number to a Redis database and the hard disk through the network terminal, and sending the map data with the latest version number to the vehicle-mounted intelligent device for displaying.
It can be understood that the Redis database and the hard disk are searched one by one through the steps, and when corresponding map data are not stored in the Redis database and the hard disk, the map data with the latest version number can be downloaded and obtained through the network terminal. By the design, the Redis database of the cache region and the map data of the hard disk are perfected. And finally, the map data with the latest version number in the Redis database or the hard disk can be sent to the vehicle-mounted intelligent device for display.
In the related art, the Redis data is stored in the memory, and meanwhile, the Redis can synchronize the memory data to the disk at regular time, that is, the data can be persisted, and the Redis can periodically write updated data to the disk or write modification operation to an additional recording file. In this embodiment, the map data with the latest version number may be downloaded to the Redis database through the network terminal, and the Redis database writes the map data with the latest version number into the hard disk according to the data persistent update mechanism. By the design, the map data of the hard disk is kept complete and updated.
In order to avoid occupying network resources, in one embodiment, a search request is periodically sent to the network terminal, where the search request is a search request of the latest version number of the map data or a search request of the map data of the latest version number. In one embodiment, the search request is added to a network request sending list and then sent. Sending search requests to a network terminal according to a preset period, and adding each search request to a network request sending list; wherein, the search requests on the network request sending list are not repeated.
It can be understood that network resources are occupied when the network terminal searches the latest version number of the map data or downloads the map data. In order to avoid frequent sending or repeated sending, a preset period is set, and a searching request is sent to a network terminal at regular time, so that the searching request is limited to be sent only once in the preset period. By adopting the design, the problem that the next search request is sent again when the last search request is not returned is avoided. Therefore, by setting the network request sending list, the search request in each preset period is added to the network request sending list. In one embodiment, the predetermined period may be several hours or several days. And for the search request of the same map data, when the last sent request is not returned, the search request cannot be sent repeatedly, and the search requests aiming at the same map data on the network request sending list are not repeated. It can be understood that the search requests for different map data are not necessarily repeated, so that the search requests on the network request sending list in the preset period are not repeated.
In the processing method of the vehicle-mounted intelligent device data, the current position information is acquired, and then the corresponding map data is acquired in the Redis database according to the position information; if the Redis database does not have the map data, searching and acquiring the map data in the hard disk; if the map data does not exist in the hard disk, the map data is downloaded through a network and the like, and the map data is stored in a Redis database and the hard disk. According to the design, on one hand, according to the priority sequence, the map data are searched in the Redis database, the hard disk and the network end from high to low in sequence, and the map data are guaranteed to be searched according to the fastest level; meanwhile, the map data is updated in time, and the accuracy of the data is ensured. In addition, the Redis database stores map data according to a preset module, so that accurate classified storage is realized, and the searching efficiency and the data acquisition efficiency are improved. On the other hand, the map data is searched and updated according to the specific position information in a targeted manner, so that the updating data volume is reduced, and the updating efficiency is improved.

Step S350, if the network terminal can be connected, searching the latest version number of the map data through the network terminal, comparing the latest version number with the existing version number of the map data stored in the hard disk, and judging whether the latest version number is the same as the existing version number of the map data stored in the hard disk; if the current version number is the same as the latest version number, the step 392 is carried out, and the map data on the hard disk are directly sent to the vehicle-mounted intelligent equipment to be displayed; if the existing version number is different from the latest version number, the process proceeds to step S360.
And step S360, if the existing version number is different from the latest version number, downloading the map data with the latest version number to the hard disk from the network terminal, and then entering step 391 to send the map data with the latest version number downloaded from the hard disk to the vehicle-mounted intelligent equipment for displaying.
Step S370, if the hard disk does not store the corresponding map data, downloading the map data with the latest version number from the network terminal to the cache area and the hard disk, and proceeding to step 391, sending the downloaded map data with the latest version number to the vehicle-mounted intelligent device for display.
And step S380, sending the map data of the cache region to the vehicle-mounted intelligent device for displaying.
And S391, sending the map data downloaded from the network end to the hard disk to the vehicle-mounted intelligent equipment for displaying.
