Embodiment 1

[0044] figure 1 It is a schematic flowchart of a method for synchronizing real-time traffic information shown in the embodiment of the present application.

[0045] see figure 1 , the method for synchronizing the real-time traffic information, including:

[0046] Step S110, storing at least part of the map road data in at least one auxiliary database, wherein all map road data are additionally stored in the main database.

[0047] In one of the embodiments, the primary database and multiple secondary databases can be set on the same server, or they can be set on different servers respectively. That is, the primary database and each secondary database can be set on different servers. In one specific implementation manner, when there are multiple auxiliary databases, all map road data are distributed and stored in different auxiliary databases. The map road data stored cooperatively by multiple auxiliary databases is the same as all the map road data stored in the main datab...

Embodiment 2

[0056] In order to further introduce the synchronization method of the real-time traffic information of the present application, see figure 2 , the method for synchronizing the real-time traffic information, including:

[0057] Step S210, pre-store all map road data in the main database, and divide all map road data according to map regions, and store map road data in each map region in corresponding auxiliary databases.

[0058] In one embodiment, the primary database is set on the primary server, and each secondary database is set on the corresponding secondary server. The master server communicates with each slave server respectively. By assigning each secondary database to a secondary server, decentralized management improves operating efficiency. In one of the embodiments, both the primary database and the secondary database are Redis databases. Specifically, Redis (Remote Dictionary Server, remote data service) is an in-memory cache database written in C language wit...

Embodiment 3

[0074] image 3 It is a schematic structural diagram of a device for synchronizing real-time traffic information shown in the embodiment of the present application.

[0075] see image 3 , this embodiment provides a device for synchronizing real-time traffic information. The device includes a storage module 310 , a query module 320 , an update module 330 and a sending module 340 . in:

[0076] The storage module 310 is configured to store at least part of the map road data in at least one auxiliary database, wherein all the map road data are additionally stored in the main database.

[0077] The inquiry module 320 is used to inquire whether the corresponding map road data in each auxiliary database is the same as the corresponding map road data in the main database according to a preset period.

[0078] An update module 330, configured to, if the map road data in the auxiliary database is different from the corresponding map road data in the main database, then the auxilia...

Abstract

The present application relates to a synchronization method, device and electronic equipment for real-time traffic information. In the method, at least one auxiliary database stores at least part of map road data, and all map road data is additionally stored in the main database; each auxiliary database queries the corresponding map road data and the corresponding map road in the main database according to a preset cycle Whether the data is the same; if the map road data in the auxiliary database is different from the corresponding map road data in the main database, the auxiliary database receives the corresponding map road data sent by the main database; the auxiliary database sends the corresponding map road data according to the received position information The corresponding real-time traffic information is sent to the client. The method of the present application avoids the simultaneous docking of many client terminals by a single primary database, and distributes real-time traffic information to corresponding client terminals through multiple secondary databases. Multiple secondary databases can balance the load, reduce the data processing load on the primary database, and improve real-time Update efficiency of traffic information.

Description

technical field [0001] The present application relates to the technical field of navigation, in particular to a method, device and electronic equipment for synchronizing real-time traffic information. Background technique [0002] TMC (Traffic Message Channel) is the abbreviation of real-time traffic information, which can reflect the traffic status of roads in the electronic map area in real time. By sending the TMC information to the electronic map of the terminal for display, travelers can be prompted to avoid congested roads and plan their driving routes reasonably. [0003] In related technologies, for the national TMC system, it is generally processed by a server, and millions of pieces of TMC information are sent to the corresponding client every minute. However, the TMC information needs to be updated in real time, and due to the large data load, it may delay the data update of some clients. Contents of the invention [0004] In order to overcome the problems exi...
