Embodiment approach

[0041] The slewing motion is the rotation motion of the above three model objects with the center line of the tower body slewing as the axis. The rotary motion of the model object obj_roate is realized by changing the h value in vgPosition(x, y, z, h, p, r) of the character object plyr_roate. Obtain the new pose of the trolley through the vgGetPos() function, and assign the new pose to plyr_rope through the vgPos() function to realize the rotary motion of the hoisting wire rope. According to the new pose and length of the hoisting wire rope, determine the new pose of the hook, and then assign it to plyr_hook to complete the slewing motion of the tower crane.

[0042] Luffing motion is the movement of the trolley, hook, and cargo on the boom. Take the trolley as a VgPart, use the change of relative pose to change the position of the trolley, and at the same time assign the new pose of the trolley to the role object of the hook and the lifting wire rope, and update the position...

Abstract

The invention discloses an operation simulation training virtual reality software system of a tower crane. The software system selects the construction site of the bicycle stadium of the 11th NationalGames of PRC and the used QTZ125 tower crane as the simulation object and adopts three-dimensional modeling software Multigen-Creator to build the tower crane three-dimensional model and the construction site scene and surrounding environment model according to the blueprint of the QTZ125 tower crane, construction site and surrounding environment; in the VC++ editing environment, the real time actuation of the tower crane model and scene model can be realized through Vega programming. The invention is the software part of the operation simulation training system of the tower crane which reappears the working process of the tower crane and the change of scene and simulates the generation and change of three-dimensional scenes such as the day, night, fog and the like so as to provide training for the driver of the tower crane.

Description

technical field [0001] The invention relates to a virtual reality software system, in particular to a virtual reality software system for tower crane operation simulation training, which is a software part of the tower crane operation simulation training system. It belongs to the field of virtual reality technology. Background technique [0002] At present, the training of tower crane drivers is completed through the way of masters leading apprentices. This traditional teaching method is affected by human factors, and there are problems such as high accident rate, long training time, non-standard training content, and weather conditions. limitations and low efficiency. With the rapid development of modern science and technology and the improvement of construction level and management level, it is possible to use computer system to provide high-quality driving training for tower crane drivers. For this reason, it is possible to research and develop a multifunctional tower c...
