Embodiment Construction

[0015] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings. The described embodiments are only part of the embodiments of the present invention, and should not be construed as limiting the protection scope of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0016] The invention provides a dispatching method of an automatic dock crane, the method comprising the following steps:

[0017] Step 1: Get the transit time of the container between the loading point and the unloading point by the automatic quay crane;

[0018] Step 2: Establish a mathematical model of container transportation time, wherein the state matrix of the system is a maximal-addition matrix A of n×n, and n represents the number of ...

Abstract

The invention discloses a dispatching method for an automatic dock crane. According to the method, on the basis of mathematics and system theories, a mathematic model of an automatic dock crane dispatching system is established, the overall robustness technology of the system is applied, the maximum changing range of the transportation time of a container between a loading point and an unloading point is determined, the running speed of a sling between different positions is low as much as possible while the departure time of the sling in any direction is not influenced; and meanwhile, goods vibration in the container elevating process and impacts and abrasion of a brake, wheels, a speed reducer, a main beam and a cable are reduced, and transportation safety and effectiveness are improved.

Description

technical field [0001] The invention belongs to the technical field of transportation dispatching, in particular to a dispatching method of automatic wharf cranes. Background technique [0002] Automatic quay crane dispatching system is a high-dimensional nonlinear complex system. It is necessary to establish a mathematical model for the automatic quay crane dispatching system to reduce the complexity and calculation amount of the system. Due to the heavy weight of the container at the terminal, when the transport speed is too fast, collisions may occur, causing life and property safety accidents, and it will also increase the number of emergency stops of the reducer, and increase the impact of brakes, wheels, reducers, main beams and cables and wear, shortening the service life of the crane. Prolonging the transit time of containers at different locations can help to solve the above problems. The key is to find the maximum variation range of container transit time so that...
