Embodiment Construction

[0061] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0062] refer to figure 1 , the first embodiment of the present invention provides a shared memory-based GPS data information query method, the method comprising:

[0063] S10: In response to the information query request sent by the terminal device, obtain the device identification and target location information from the information query request;

[0064] It should be noted that the execution subject of the method in this embodiment is a data server for storing GPS data information, and of course, it may also be other devices with similar functions, which is not limited in this embodiment.

[0065] It can be understood that the terminal device is a device that needs to query GPS data information, such as a smart phone, a tablet computer, a notebook computer, a PC, a navigator, or a server that needs to query GPS da...

Abstract

The invention discloses a shared memory-based GPS data information query method and system, and belongs to the technical field of shared memory computers. The method comprises the following steps of: in response to an information query request sent by terminal equipment, obtaining an equipment identifier and target position information from the information query request; searching a memory area corresponding to the equipment identifier from a shared memory according to the equipment identifier; extracting GPS data information corresponding to the target position information from the memory area; and sending the extracted GPS data information to the terminal equipment, so as to reduce the read-write for persistent database clusters and improve the service performance.

Description

technical field [0001] The invention relates to the technical field of shared memory computers, in particular to a method and system for querying GPS data information based on shared memory. Background technique [0002] At present, the GPS data of the device's global positioning system is stored in a persistent database cluster (Mysql relational database management system, Hbase distributed, column-oriented open source database). The persistent database cluster has a large capacity and can store massive amounts of data. [0003] But there are following defects in this scheme: [0004] (1) A large number of reads and writes to the persistent database will lead to high I / O load of the server disk input and output, large performance loss, and will affect other services of the server; [0005] (2) The restart or failure of the persistent database cluster will cause the entire service system to be paralyzed and unable to provide services normally. [0006] The above content is...
