Dynamic positioning and scheduling method and system based on GIS (Geographic Information System)

Abstract

The invention relates to a dynamic positioning and scheduling method and system, which integrate satellite positioning, a digital map and a GIS (Geographic Information System) into a whole and are suitable for real time positioning and scheduling of fleets. The dynamic positioning and scheduling method comprises the following steps of: presetting a parameter required by dynamic positioning and scheduling; carrying out road matching algorithm processing according to GPS (Global Positioning System) positioning information and the GIS; setting each fleet as one category; calculating the positionwhere the fleet arrives every X seconds within 0-T min; judging whether the fleet deviates a preassigned path; judging whether other fleets are in a safety car distance value L0; if not, sending alarming information; judging whether the traveling average speed of the fleet is less than a set car speed value V0, if so, transferring to a standby path; judging whether the fleet arrives a destination, if so, clearing the fleet in the categories; repeating the steps until category operations of all fleets are completed. Therefore, by utilizing the dynamic positioning and scheduling method and system, the real time positioning and monitoring of a plurality of fleets can be realized, alarming can be given when conflict conditions occur, and intelligent command scheduling functions can be realized.

Description

technical field [0001] The present invention relates to the field of dynamic positioning dispatch command intelligent navigation based on GIS geographic information system, in particular to a dynamic positioning dispatch command intelligent navigation method and system integrating GPS satellite positioning, digital map and GIS. Background technique [0002] GPS is the abbreviation of Global Positioning System (Global Positioning System) in English, and its Chinese abbreviation is "ball position system". GPS is a new generation of space satellite navigation and positioning system jointly developed by the US Army, Navy and Air Force in the 1970s. It has all-round real-time three-dimensional navigation and positioning capabilities in sea, land and air. The GPS system can be used not only for surveying and navigation, but also for speed measurement and time measurement. Through the accurate positioning of the satellite signal received by GPS, the vehicle's driving route, positi...

Problems solved by technology

Although the existing car navigation system can provide intelligent navigation information for a single vehicle, and some even combine road traffic flow and traffic conditions to make real-time intelligent navigation, but for the dynamic positioning of fleets or even multiple fleets, especially in large-scale When it is necessary to command and dispatch multiple convoys during the event, the existing navigation system does not take into account factors such as multi-road sections, multiple convoys, and safety distances between convoys, so it has limitations in use
