Of course, other devices capable of implementing corresponding functions may be adopted as the device, and this embodiment is not limited to this.
As shown in fig. 1, after an actual operator wears a VR display device 301, the VR display device 301 is configured to output current view angle and position information of the virtual operator to a host 201 of a virtual reality server 200, the host 201 is configured to output a corresponding frame calling signal to a simulation machine server 101 according to the current view angle and position information, the simulation machine server 101 is configured to output a real-time frame signal of a computerized workstation in a current view of the virtual operator to the host 201 according to the frame calling signal, a main control room three-dimensional model in different virtual environments is stored in the host 201, the current main control room three-dimensional model is further configured to be combined with a real-time frame of the computerized workstation in the current view of the virtual operator, and the combined three-dimensional image is output to the VR display device 301, and then the VR display device 301 outputs the combined image of the real-time frame of the current main control room three-dimensional model and the computerized workstation in the current view of the virtual operator An image;
the user input unit 302 of the user interface 300 is configured to input a control instruction of an actual operator to the simulator server 101 (that is, the actual operator inputs the control instruction to the simulator server 101 through the user input unit 302), the simulator server 101 is further configured to respond to the control instruction according to the nuclear power plant instrument control system model and the power plant thermal hydraulic model, and display a feedback result to the actual operator in a form of a picture, specifically, to form an updated real-time picture signal of a computerized workstation in a current field of view of the virtual operator, where the updated real-time picture signal is synthesized by the host 201 and then output to the VR display device 301, and then the VR display device 301 outputs a synthesized image of a current three-dimensional model of the main control room and an updated real-time picture of the computerized workstation in the current field of view of the virtual operator.
In this embodiment, VR glasses (VR display device 301) are used to provide a virtual image of the main control room to the user (actual operator) that includes the virtual environment of the main control room and the real-time view of the computerized workstation in the current field of view of the virtual operator. The user input unit 302 of the user interface 300 is directly connected to the simulator server 101, the control commands (including control commands and monitoring requirements) of the actual operator are directly transmitted to the simulator server 101, the simulator server 101 receives and responds to the control commands, and the feedback is embodied in the output picture signal to obtain the updated real-time picture of the computerized workstation in the current field of view of the virtual operator, and the updated real-time picture is synthesized with other images in the host computer and then displayed to the user through the VR display device 301, so that a complete loop of input and feedback in the virtual reality environment is formed.

The actual operator uses the joystick (position control unit 303) to control the virtual operator in the virtual environment to move or switch the standing posture/sitting posture in the main control room, so that the actual operator can control the position and the state of the virtual operator in the virtual scene without moving and execute corresponding training tasks, the area of an actual training field required by each group of actual operators is greatly reduced, and the space utilization rate is effectively improved.
Since the focus of the virtual reality technology-based nuclear power plant main control room simulator system is to simulate an operator in a minimized space to monitor a power plant using a human-machine interface of a main control room, physical movement of the virtual operator in the main control room is not the focus of the present invention, and in the embodiment, the position movement and station/sitting posture switching of the virtual operator are realized only by the position manipulation unit 303 (joystick), and the power plant is monitored in the virtual main control room by the VR display device 301.
Preferably, the host 201 of the virtual reality server 200, in combination with the current viewing angle and position information of the virtual operator output by the VR display device 301 and the manipulation instruction output by the position manipulation unit 303, calculates the computerized workstation in the current field of view of the virtual operator, and forms a corresponding frame calling signal to the simulation machine server 101, so as to more accurately call the real-time frame signal of the computerized workstation in the current field of view of the virtual operator, so that the host 201 acquires the required frame signal, and completes the real-time rendering of the three-dimensional image.
In this embodiment, the host 201 of the virtual reality server 200 is configured to generate a real-time image of the main control room in the virtual environment by using a computer three-dimensional graphics program, wherein the real-time image of the computerized workstation in the current field of view of the virtual operator provided by the simulation server 101 includes an image formed by affine transformation and projecting the real-time image onto a current three-dimensional model of the main control room, and also includes real-time status information (including moving position, standing/sitting status, etc.) of the virtual operator in the virtual environment controlled by the actual operator through the joystick (the position manipulation unit 303), and the synthesized three-dimensional image is displayed to the actual operator through VR glasses. When training tasks for plant-related operations need to be performed, the actual operator may issue control instructions to the simulator server 101 using the user input unit 302 in the user interface and observe the feedback results in the VR glasses.
As mentioned above, the virtual environment conditions (such as lighting design, decoration material and color scheme) corresponding to each training scenario can be adjusted, the specific parameters (such as the number of devices and the appearance of the devices included in the main control room) of the three-dimensional model of the main control room corresponding to each training scenario can also be adjusted, in order to achieve the adjustment, in this embodiment, the virtual reality server 200 is provided with the maintenance input unit 203 for inputting the adjustment parameters of the maintenance personnel to the host 201 (i.e. the maintenance personnel inputs the adjustment parameters to the host 201 through the maintenance input unit 203), the host 201 is further configured to adjust the height data of the virtual operator and the eye height data of the virtual operator in standing/sitting posture according to the adjustment parameters, so as to adapt to different actual operators, and select the training scenario to be simulated, adjust the virtual environment conditions or adjust the specific parameters of the three-dimensional model of the main control room, modifications can also be made to the program code.
In addition, since it is inconvenient for an actual operator to determine the position of a keyboard and a mouse (i.e., the user input unit 302) for inputting a control command when wearing VR glasses, a certain difficulty is caused to the operation of the simulation training, in order to overcome the difficulty, the virtual reality server 200 is further provided with a camera unit 202 for capturing an image of the user input unit 302 of the user interface 300 in real time to monitor the user input unit of the user interface and outputting the captured image to the host 201 of the virtual reality server 200, the host 201 is further configured to integrate the image captured by the camera unit 202 into an image generated by the host of the virtual reality server, specifically, to combine the image captured by the camera unit 202 with a current main control room three-dimensional model and a real-time screen of a computerized workstation in the current field of view of the virtual operator, and then output the combined three-dimensional image to the VR display device 301 of the user interface 300, so that the user can call up the real-time image of the user input unit 302 for inputting the control command, i.e., see the real-time image of the keyboard and the mouse for inputting the control command, and the user can call up the image to cooperate with the operation of the keyboard and the mouse, thereby providing convenience to the user.
Preferably, the host 201 of the virtual reality server 200 is capable of synthesizing the main control room three-dimensional model, the real-time screen signal output by the simulator server 101, and the image of the user input unit 302 captured by the image capturing unit 202, and outputting the synthesized image to the VR display device 301 in real time.
The simulation machine system of this embodiment is more flexible than the conventional simulation machine technology, and specifically, the simulation machine system of this embodiment can freely adjust the environmental condition and the layout condition of the virtual main control room at each stage of the design, and can verify different design schemes of each aspect (such as illumination, layout, equipment appearance, etc.) of the virtual main control room at any time. In the conventional simulator technology, the main control room simulator needs to be established after deduction of the layout and the equipment appearance design of the main control room in a MOCKUP mode, and the main control room is difficult to modify in a large range after being established. In this respect, the main control room simulator system based on the virtual reality technology according to this embodiment may replace MOCKUP activities required in the human factor engineering review outline, and embody factors such as illumination and material reflection into a model for design verification before establishing a real main control room simulator, so that the design result is more real and reliable.
In addition, the main control room simulator system based on the virtual reality technology can greatly reduce the occupied area of the simulator. Taking the simulator training center of a power plant as an example, a set of traditional main control room simulator platform needs about 300 square meters of room to train a set of operators, and each operator of the main control room simulator system based on the virtual reality technology only needs one single station to simulate the working environment in the main control room, and a set of operators only need about 30 square meters of room to complete the training task, thus greatly improving the space utilization rate. For a simulator verification platform of a designer, one set of VR display equipment can be used for simulating a scheme of a plurality of sets of main control rooms, and the reusability of a main control room simulator system is improved.
