A virtual command cabin for large hoisting operations and its working method

Abstract

The invention belongs to the field of safety control on lifting operations and provides a virtual command module for large lifting operations and a working method of the virtual command module. The module comprises a live-action monitoring system, a virtual guiding system, a precise positioning system and a lifting mechanical analysis system. Visualization of global field monitoring of a lifting site can be realized, a virtual lifting rehearsal model is constructed on the basis of a BIM (building information model), and simulation and route optimization of a lifting process are realized through setting of working conditions and lifting parameters, so that lifting risks are mastered in advance, and a lifting scheme conforming to actual requirements is made; besides, through precise positioning and lifting mechanical analysis, automation and informatization of collision prevention and safety control on lifting are realized, accurate and direct early-warning information is provided for front-line commanders, unified and standard lifting commands are given to crane drivers, the crane drivers are assisted in completing lifting operations smoothly and safely, and the safe, real-time and effective technical support is provided for the large lifting operations.

Description

technical field [0001] The invention belongs to the field of hoisting operation safety control, in particular to a large-scale hoisting operation virtual command cabin and a working method thereof. Background technique [0002] With the rapid development of China's economy, domestic petrochemical, water conservancy and hydropower, and infrastructure projects are becoming larger and larger, and their stand-alone equipment is also becoming larger and more sophisticated; and due to the gradual implementation of modular construction, the volume is larger, Larger modules that weigh more are also emerging. The large-scale and heavy-duty hoisting objects make the hoisting process requirements more and more stringent. It is necessary to ensure the accurate hoisting and anti-collision of the hoisting objects, which is far more difficult than the previous hoisting operations. At the same time, according to the relevant situation of special equipment safety in the first half of 2015 a...

AI Technical Summary

Problems solved by technology

[0003] Due to the large size of the hoisting object, the crane is prone to overturning during the hoisting process, and the hoisting site is also prone to structural damage under the condition of excessive load; at the same time, there are many blind spots for the crane driver during the hoisting process; moreover, the site environment Noisy and many cross operations require the command personnel to cooperate with the crane driver to complete the hoisting operation. However, the joint command operation of multiple people will make it difficult to guarantee the communication effect, and it is impossible to guarantee the accuracy and accuracy of the operation only by the commander's own experience to judge whether the hoisting is safe. Safety, inconsistent instructions and irregularities also have a huge negative impact on the operation of the crane driver, endangering the safety of hoisting operations
