High-efficiency real-time electronic map fence realization method based on big data

Abstract

The invention discloses a high-efficiency real-time electronic map fence realization method based on big data. Distributed storage of high-efficiency real-time electronic map fence information is realized through adoption of architecture of big data; the electronic map fence information is searched through distributed computation; and information indicating that a user terminal enters or exits an electronic map is triggered. The method comprises the steps that when the electronic map fence information is added to a system, the electronic map fence information is stored in a distributed storage component Hadoop, and an index is added to the electronic map fence information; when an information queue of the system receives position information of the user terminal, the position information is transmitted to a distributed computation component Spaprk for processing and the distributed storage component Hadoop for information backup; and the distributed computation component Spaprk receives the position information of the user terminal, the electronic map fence information around users is searched rapidly and corresponding temporary files are generated; and when the system detects that a certain user terminal enters or exits a certain electronic map fence, corresponding information is triggered to be sent to the user terminal.

Description

technical field [0001] The invention relates to the fields of big data, cloud computing and location services, in particular to a method for realizing an electronic map fence based on big data, which is efficient, real-time and manageable in the background. Background technique [0002] In the location service system, the electronic map fence is a very important function, that is, to delineate a specific area on the online map or GIS map. The shape of this area is often circle, rectangle, triangle and polygon. Or exit the area, the system will generate and push various messages. [0003] The electronic map fence is an extremely widely used function, including the preservation of important objects, the prevention of loss of the elderly and children, the management of hazardous chemicals, anti-aircraft and anti-riot, and electronic tour guides. [0004] At present, the electronic map fence of most location systems is mainly stored on the terminal offline. If the electronic ma...

Problems solved by technology

[0006] This data update method is inefficient, low in real-time performance, and poor in user experience. It is often necessary to download the electronic map fence information of the entire area to update one or two warning messages or prompt messages.

In addition, information update depends on users' active or passive downloading, which will cause the system to monitor users' downloading behavior to confirm which users have not updated, which increases the development cost of the location service system

[0007] The reason why the electronic map fence adopts the above method is mainly limited by the traditional relational database technology

The electronic map fence information stored in the location service system is as high as hundreds of thousands of rows. When a user enters or exits the electronic map fence area, the system needs to perform large-scale queries on these hundreds of thousands of rows of data, which greatly consumes the performance of the server. When the number of users is tens of thousands, the location service system will collapse
