Problems solved by technology

The geo-fence related technologies currently used are all static geo-fences. This method can actively push static hidden danger information such as accident-prone areas to associated vehicles, but it is far from meeting the requirements of hidden danger control.

Embodiment

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0037] One, first explain the parameter definitions involved in the present invention:

[0038] Road network edge cell: divide the road network into a grid. When a grid [x, y] contains road edge e, the grid is called an edge cell of edge e, such as figure 2 Shown in the middle left figure. Use the quintuple (x,y,e,n s ,n e )To represent. Among them, x, y represent the cell grid coordinates, e represents one of the edges, ns, ne represent the intersection of the edge and the cell;

[0039] Instantaneous fence area: At a certain time T, the area covered by the instantaneous geofence constructed ...

Abstract

The invention discloses an information pushing system and method based on a mobile geofence. An internet of vehicle information management system constructed through the method can make drivers obtain safety information of moving targets so as to provide active safety service. According to the method, dynamic fences are established with the geographic positions of the moving targets as references; information is pushed to associated objects in the fences; meanwhile, the multiple moving targets in the system are tracked. The invention further discloses a method for parallel management of the multiple dynamic fences. By means of the position information pushing system and the dynamic fence management method, safety driving information can be pushed to the surrounding associated objects accurately in time, and therefore traffic accidents are avoided.

Description

technical field [0001] The present invention relates to the technical fields of Intelligent Transportation System and Internet of Things, in particular to a mobile geographic fence information push system and method thereof. Background technique [0002] The Internet of Vehicles (IOV) is an important development direction in the field of the Internet of Things, and building active safety services is one of the important goals of the current Internet of Vehicles system development. Depending on the state of the accident and the response requirements, active safety technology generally focuses on two stages: the emergency avoidance stage at the moment of the accident and the hidden danger control stage when the vehicle is in normal driving. The former mainly relies on the dedicated short-range communication technology (Dedicated Short Range Communications, DSRC) between "vehicle-vehicle-road" and vehicle active control technology to achieve accident avoidance (Accident Avoidan...
