An early warning method and system for broadcasting driving safety reminder information online

Abstract

The invention discloses an early warning method and a system for online broadcasting driving safety prompts. The method comprises steps: a server carries out segmentation pretreatment on warning point data according to grids, and first pretreated warning point data are obtained; the first pretreated warning point data are correspondingly stored according to numbers of the grids; a terminal judges whether the warning point data are stored locally or whether the already-stored warning point data are the latest data or whether the already-stored warning point data are out of date, and a judgment result is obtained; when the judgment result is that the warning point data are not stored locally or the already-stored warning point data are not the latest data or the already-stored warning point data are out of date due to a version factor, the terminal initiates a downloading request carrying the grid numbers to the server; and according to the grid numbers, the server obtains first pretreated warning point data corresponding to the grid numbers, the terminal is returned, and early warning broadcasting for the safety prompts is started.

Description

technical field [0001] The invention relates to broadcasting technology, in particular to an early warning method and system for online broadcasting of driving safety prompt information. Background technique [0002] In the process of implementing the technical solutions of the embodiments of the present application, the inventors of the present application at least found the following technical problems in the related art: [0003] In the current existing scheme, during the driving process of the user, the user can use the electronic map device to broadcast safety reminders such as the speed limit of the road ahead of the user, frequent accidents, and traffic intersections in voice mode, and give the user an early warning, so that the user Adjust the driving style in time to help users drive more safely and standardizedly. Among them, information such as road speed limit, frequent accidents, and traffic intersections are collectively referred to as driving safety warning p...

Problems solved by technology

The disadvantage of the "offline" type is: the data update is not timely and the update operation is cumbersome, and each update must be updated through the computer and the data line, which cannot be updated in real time. Misreports and omissions, causing confusion for users when driving

On the one hand, the processing performance requirements of the server are high, relying on more or higher-configured servers; on the other hand, the processing delay of the server is long, resulting in slow response speed

[0012] 2) Cached data cannot be reused, wasting network traffic and terminal power consumption

Although some of the data previously cached at point J is also surrounded by circle S2 (the intersection of circle S1 and circle S2), theoretically this part of data can be reused, but in order to reuse this part of data, it needs to be sent to the server Request the data contained in the irregular shape, that is, the remaining part of the circle S2 after removing the intersecting part. On the one hand, it is difficult to describe the irregular shape. On the other hand, the processing complexity of the server is further increased, and the gain outweighs the gain. Therefore, it is not actually used. Instead, Each time the cache is only used as a temporary cache, it is discarded after use, and the persistent cache is not used. The data contained in the new circular area is completely requested every time, so that the data is repeatedly cached, wasting part of the network in vain traffic and increases the power consumption of the terminal

[0014] For the above problems, there is no effective solution in the related art
