Map aggregation vehicle refreshing method based on distributed calculating

Abstract

A map aggregation vehicle refreshing method based on distributed calculating comprises two parts, namely, global position system (GPS) data receiving and analyzing on a server-side and client-side map aggregating on a client-side, wherein the two parts are carried out without sequence. A server receives and analyzes the GPS data, specifically, a GPS server receives real-time GPS data sent from a vehicle terminal through an Internet, and the main server of a GPS calculating cluster carries out adjustment according to current load of each work station, and allocates GPS data packages to each work station to carry out data processing. The client-side map aggregating specifically comprises that the client-side requests to obtain the GPS data of all vehicles from the main server of the GPS calculating cluster, sends the longitude and latitude coordinates and the visual field size of a current map range to the main server of the GPS calculating cluster, and requests the main server to carry out statistical calculation of map aggregating. The map aggregation vehicle refreshing method based on the distributed calculating uses a distributed calculating technology to solve the bottleneck problem of vehicle display quantities, guarantees the improvement of system performance, and meanwhile enhances the expansibility of the system, and reduces the cost of maintenance and upgrade.

Description

technical field [0001] The invention belongs to the field of GPS monitoring systems, and in particular relates to a distributed computing-based map aggregation vehicle refreshing method. Background technique [0002] At present, in the GPS monitoring system, the most commonly used function is to display and refresh the real-time position of the vehicle and other auxiliary information in real time on the electronic map. Due to the limitations of the PC's processor and display card processing capabilities and network transmission bottlenecks, the number of vehicles displayed on the electronic map has a certain upper limit. After exceeding this limit, the performance of the system will decline significantly, affecting The normal use of other system functions, so how to break through the bottleneck of the number of vehicles displayed, so that users can see as much real-time vehicle information as possible on the system, has become a technical problem. The commonly used solution...
