At image, while also containing manipulation of physical person and being existed by the virtual operator that control stick (position manipulation unit 303) controls
Real time status information (including shift position, standing/seated position etc.) in virtual environment, the 3-D view after synthesis passes through again
VR glasses show manipulation of physical person.When needing to execute the training mission of power plant's relevant operation, manipulation of physical person, which can be used, to be used
User input unit 302 in the interface of family sends out control instruction, and the observation feedback knot in VR glasses to analog machine server 101
Fruit.
It is preceding to have addressed, the corresponding virtual environment condition of each Training scene (such as Lighting Design, finishing material and scheme of colour
Deng) adjustable, the design parameter (equipment for including in such as main control room of the corresponding main control room threedimensional model of each Training scene
Quantity and equipment shape etc.) also it can adjust, in order to realize the adjustment purpose, in the present embodiment, set in virtual reality server 200
Maintenance input unit 203 is set, being used to input the adjusting parameter of maintenance personnel, (i.e. maintenance personnel passes through maintenance to host 201
Input unit 203 inputs adjusting parameter to host 201), the host 201 is additionally operable to adjust virtual manipulate according to the adjusting parameter
The height data of member, adjustment are in the high data of eye of the virtual operator of stance/sitting posture, to adapt to different manipulation of physical persons, with
And selection is gone back to Training scene, adjustment virtual environment condition or the design parameter for adjusting main control room threedimensional model simulated
It can modify to program code.
Further, since manipulation of physical person is inconvenient to determine the keyboard and mouse instructed to input control when wearing VR glasses
The position of (i.e. user input unit 302) causes certain difficulty to the operation of simulated training, empty in order to overcome the difficulty
