Navigation control device and navigation control method applicable to collaborative transportation of cranes

Abstract

The invention aims at solving the problems of collaborative transportation of current cranes and provides a network-based multi-crane collaborative transportation navigation system and a network-based multi-crane collaborative transportation navigation method, wherein the system and the method are applicable to large heavy-load and complex working conditions, reliable in performance and strong in adaptability. The system comprises a network operation monitoring server, a loading box lower computer, a four-axis aerial photographing aircraft, a loading box condition monitoring module, a wireless communication device, a loading box position indication light, a crane condition monitoring module and a crane lower computer. According to the navigation control method, sequential and accurate collaboration of a whole crane queue can be ensured by planning a comprehensive line in a manner of combining data fed back by the crane lower computer and the loading box lower computer with GPS (Global Position System) information and weather information and monitoring action and direction of each individual crane. The device and the method have the beneficial technical effects of being capable of effectively inhibiting the swinging of heavy goods caused by complex road conditions in a transportation process and applicable to transportation of precise, valuable and large loads.

Description

technical field [0001] The invention relates to the field of multi-crane cooperative operation, in particular to a network-based multi-crane cooperative transportation navigation system and method suitable for long-distance transportation of large heavy loads. Background technique [0002] Hoisting equipment is an important tool for factories, railways, ports and other departments to realize the mechanization of material handling, among which cranes are widely used because of their good maneuverability and large load capacity. In recent years, with the rapid development of the manufacturing industry, heavy and large-scale loads and increasingly complex hoisting operation environments have put forward higher requirements for cranes. Restricted by coordination ability, load capacity, etc., a single crane cannot fully meet the current requirements. [0003] With the rapid development of computer technology and control theory, the degree of automation of cranes has been greatly...

AI Technical Summary

Problems solved by technology

At present, for the hoisting and transportation of large and heavy loads, it is generally used to decompose into multiple parts and transport them separately, and then assemble and debug, which is time-consuming and laborious, and severe vibration will inevitably occur during transportation, which is not suitable for some precision or large loads. The transportation of multiple cranes can solve this problem very well, that is, the heavy objects can be transported to the destination without decomposing the heavy objects, and the flexible rope characteristics of the crane's steel wire rope can offset the transportation process to a certain extent. However, due to the traditional multi-crane cooperative transportation, on-site command and manual control are generally used, which completely rely on the operator's experience, and the degree of automation is low. It is impossible to coordinate the crane movements and monitor the status of heavy objects in real time and accurately. Effectively inhibit the swing of heavy objects, the level of heavy objects cannot be guaranteed, and it is not suitable for carrying valuables, and accidents may occur due to the swing of heavy objects, resulting in irreparable losses

In addition, because traditional multi-crane cooperative transportation cannot realize real-time and effective perception of the environment, the requirements for the external environment of transportation, such as wind, rain, snow, and road conditions, are relatively high. At the same time, the resistance to changes in the external environment is poor, and the transportation efficiency is low. There are certain risks, which also prevents the multi-crane coordinated transportation from being widely used

Therefore, there is currently no safe and reliable navigation control method, resulting in the application of multi-crane cooperative transportation limited to short-distance, low-speed, small and light-load transportation, and has not been widely used in long-distance hoisting and loading operations in large-scale, heavy-duty and complex working conditions.
