Application method of quantum compass at a port and a quay

Abstract

The present invention provides a method that one or more quantum compass positioning sensors are mounted on a port facility for realizing functions of walk positioning, deviation correcting and anticollision. The quantum compass positioning sensor employs a quantum positioning system (QPS) and combines the earth magnetic field and a gravitational field for judging acceleration. The QPS can measure a displacement, and determine a current absolute position by comparing the universal gravitation map of the earth with an actual gravity. A global coordinate graph of a container quay is established through the data measured by the quantum positioning sensors, and then a walking path of the port facility is plotted, such as rubber tyre crane, rail mounted quayside crane, container truck, automated guided vehicle and the like. Functions of walk deviation correcting, positioning and anticollision can be realized by the mounting of one or more quantum compass positioning sensors on the rubber tyre crane, rail mounted quayside crane, container truck, automated guided vehicle and the like.

Description

Technical field [0001] The patent of the present invention relates to the application in loading and unloading operations of port equipment in container terminals, and is especially suitable for positioning, anti-collision and deviation correction of field bridges, quayside bridges, container trucks, and automatic navigation vehicles. Background technique [0002] At present, the positioning, deviation correction and collision avoidance methods of container terminal equipment are realized by GPS positioning method, laser scanning positioning method, image positioning method, magnetic nail positioning method and so on. During the realization of the project, it was found that GPS positioning satellites are vulnerable to artificial data tampering, which leads to data errors and requires regular correction. In the container yard, the GPS signal of the field bridge and the GPS signal of the automatic navigation car will be interfered by the height of the quay bridge, and cannot be...

Problems solved by technology

During the realization of the project, it was found that GPS positioning satellites are vulnerable to artificial data tampering, which leads to data errors and requires regular correction. In the container yard, the GPS signal of the field bridge and the GPS signal of the automatic navigation car will be interfered by the height of the quay bridge, and cannot be positioned normally; laser scanning The positioning is easily affected by the weather; the image positioning is easily affected by the weather; the magnetic nail positioning method will be limited by the road surface

Currently there is no better workaround on ports
