RTG navigation locating and container position monitoring system

Abstract

The invention relates to an RTG navigation positioning and box position monitoring system, which comprises a GNSS reference station subsystem for generating and broadcasting GNSS difference correction, a TOS interface subsystem for providing distribution information of a container and operating instruction information, a center subsystem for acquiring, storing and forwarding the difference correction and the distribution information of the container, and a plurality of GNSS mobile station subsystems for receiving the GNSS difference correction and the distribution information of the container, automatically acquiring the operating instruction information, determining a GNSS coordinate of RTG according to the GNSS difference correction and GNSS signals received by the GNSS mobile station subsystems, determining a hanger position according to the GNSS coordinate and the installation deviation between a GNSS antenna and an RTG hanger, determining the position of the RTG in a heap, comparing the hanger position of the RTG and the box position of a box to be operated in the operating instruction information, and allowing a turn lock mechanism to act when the distance of the hanger position and the box position reaches or is smaller than a threshold value.

Description

technical field [0001] The invention relates to the monitoring field of container terminals and container yards, in particular to an RTG (Rubber-Tyre Gantry, tire crane) navigation positioning and container position monitoring system. Background technique [0002] The international shipping industry plays an extremely important role in the development of world trade and economy. At the same time, the steady growth of world economy and trade provides opportunities for the development of the shipping industry. my country has become a major shipping country in the world, and its development plays a decisive role in the development of my country's national economy, foreign trade, and even the world economy and trade. High-efficiency ports are inseparable from high-efficiency machinery and high-tech applications, including the application of GNSS (Global Navigation Satellite System, Global Navigation Satellite System) control systems on wharf tire cranes. [0003] As an importan...

AI Technical Summary

Problems solved by technology

It is a very time-consuming and error-prone process to realize the container position monitoring of tire cranes by manual confirmation and input, especially when the storage yard enters the peak operation and the driver works for a long time.

Moreover, due to special weather, insufficient light, dense containers in the yard, unclear marking lines in the yard, complex environment, etc., the driver's vision will be greatly affected, and it may not be possible to judge the location of the RTG, so that it is impossible to find the correct operation box. bit, which greatly affects the working efficiency of RTG
