Method and simulator for virtual reality training of crane operation

Abstract

The invention relates to a method and a simulator for virtual reality training of crane operation. The method comprises the following steps that a controller calculates the operation state parameters of a crane according to the indoor operation status of simulated driving operation in accordance with the kinematics and the dynamic model of the crane; the simulation precision of a six-freedom degree movement platform of a Stewart space is set, the controller converts the calculated operation state parameters of the crane into a driving instruction of the six-freedom degree movement platform of the Stewart space and sends the instruction to the six-freedom degree movement platform of the Stewart space, and the six-freedom degree movement platform of the Stewart space correspondingly operates so that the corresponding real-time movement state is provided. The method and the simulator can be used for operation training on cranes, such as a port bank container crane and a bridge type bucket-grabbing crane, the integration degree of functions is high, the layering feeling of a virtual menu space is strong, the dynamic simulation effect is real, and parameters of a training environment can be customized.

Description

technical field [0001] The invention relates to the field of crane operation training, in particular to a virtual reality training method and simulator for crane operation. Background technique [0002] With the rapid development of virtual reality technology, the crane training simulator has also made great progress through the joint efforts of many scholars and practical users. [0003] A general simulator has three parts: a training platform (vibration system, cab system), an instructor platform (coach system, monitoring system) and a simulation model (visual system, audio system). It is a typical semi-physical simulation training device. Equipped with an electronic control system, the composition of the entire teaching simulation system is more complex, the simulation motion effect is not ideal, the virtual environment is not good enough, and the price is high, there are many faults, low reliability, and lack of promotional value. [0004] Generally speaking, there are ...

[0003] A general simulator has three parts: a training platform (vibration system, cab system), an instructor platform (coach system, monitoring system) and a simulation model (visual system, audio system). It is a typical semi-physical simulation training device. Equipped with an electronic control system, the composition of the entire teaching simulation system is more complex, the simulation motion effect is not ideal, the virtual environment is not good enough, and the price is high, there are many faults, low reliability, and lack of promotion value

[0004] Generally speaking, there are many problems in today's crane training simulators, such as low functional integration, unsatisfactory simulation motion effects, unsatisfactory visual effects, low immersion, and unrealistic dynamic simulation effects, etc.
