Collision detection early warning system and method thereof

Abstract

The invention relates to the technical field of collision detection and early warning of objects, and discloses a collision detection and early warning system and method, which can support cloud collision detection and early warning of massive objects. The collision detection and early warning system comprises a management server and a plurality of detection servers, wherein a predetermined geographic region is divided into a plurality of blocks in advance; the management server stores a corresponding relationship between each block and the plurality of detection servers; the management server is used for receiving a collision detection request, determining the first block where an object is located and adjacent blocks of the first block according to position information of the object in the request, determining a detection server set corresponding to the first block and the adjacent blocks of the first block according to a corresponding relation, and sending the request to each detection server in the detection server set; and the detection server is used for updating the cache of the first block according to the information of the object in the request after receiving the request, and completing collision detection of the object with other objects in the cache of the first block and the object in the cache of the adjacent block.

Description

technical field [0001] The present application relates to the technical field of object collision detection and early warning. Background technique [0002] The collision detection and early warning system is used to detect in real time whether the current position of an object may collide with other objects in the same time and space range around it, and if there is a possibility of collision, an early warning will be triggered. The system will cache the latest position point of each object and some attribute information of the object (such as acceleration, speed, heading angle, altitude, object boundary, etc.), when a new collision determination request arrives, it will follow the information cached in the memory Do collision detection calculations and return the results to the requester. Its response speed is an important indicator to measure the quality of the system. For example, after a vehicle sends a collision detection request, the vehicle can receive the result o...

AI Technical Summary

Problems solved by technology

However, when there are a lot of latest location points and object attribute information cached in the system, the memory limit of a single server will be reached.

When the collision detection judgment of a new object continues to arrive, it cannot be stored in the memory of a server, so that the service cannot be continued

[0004] One solution is to increase the memory of a single server, but the server hardware has an upper limit, and the memory of a single server cannot be upgraded indefinitely, so when the request volume exceeds a certain level, this solution cannot solve this problem

[0005] In short, the existing technology has the problem of being unable to support cloud collision detection and early warning of massive objects
