Problems solved by technology

Because the tire crane equipment is very large and is very close to the container positions on both sides, the driver's cab is very high from the ground. The driver manipulates these huge mechanical equipment to walk long distances in a straight line in a very narrow space in the container yard. It is very difficult to control the tire crane to walk in a straight line by visual control, and it is easy to cause a box collision accident due to the deviation of the cart; it can be seen that it is very difficult to realize the anti-deviation control of the tire crane only by manual control, especially when the driver is tired and working for a long time. in this way

Abstract

The invention relates to a deviation-preventing controller for a tyre crane, comprising a first GNSS receiver and a second GNSS receiver, an embedded processor and a PLC; wherein the antenna of the first GNSS receiver and the second GNSS receiver are installed at a power supply room side or a power room side of a RTG cart for respectively outputting first GNSS information and second GNSS information, the embedded processor is used for calculating first horizontal distance and second horizontal distance the first GNSS receiver and the second GNSS receiver deviate from a track datum line according to the first GNSS information and the second GNSS information, the PLC is used for adjusting proceeding direction of the RTG cart according to the first horizontal distance and the second horizontal distance. With the deviation-preventing controller adopted, automatic deviation correction can be carried out on proceeding path of the cart, so that labor intensity of cart drivers can be greatly reduced, wharf working efficiency is improved and the number of collision accidents is also reduced.

Description

technical field [0001] The invention relates to the monitoring field of container terminals and container yards, in particular to a tire crane anti-deviation controller. 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] RTG (Rubber-Tyre Gantry, tire crane) is an important operating tool for contain...
