Description

Technical Field

[0001] This invention relates to the field of VR simulation, and more particularly to a scenario simulation signal shielding space, a scenario simulation room, and a scenario simulation system. Background Technology

[0002] Virtual Reality (VR) simulation technology, also known as analog technology, is the technology of using one system to imitate another real system. Virtual simulation is essentially a computer system that can create and allow users to experience a virtual world. This virtual world is generated by a computer and can be a reproduction of the real world or a hypothetical world. Users can interact naturally with the virtual world through multiple sensory channels such as vision, hearing, and touch. It creates a three-dimensional virtual world for users in a simulated way, reflecting the changes and interactions of physical objects in real time. Through auxiliary sensing devices such as head-mounted displays (HMDs) and data gloves, it provides users with a three-dimensional interface to observe and interact with this virtual world, allowing users to directly participate in and explore the role and changes of simulated objects in their environment, creating a sense of immersion. VR technology is the culmination of the integration of various high technologies, including computer technology, computer graphics, computer vision, visual physiology, visual psychology, simulation technology, microelectronics technology, multimedia technology, information technology, stereoscopic display technology, sensing and measurement technology, software engineering, speech recognition and synthesis technology, human-computer interface technology, network technology, and artificial intelligence technology. Its realism and real-time interactivity provide strong support for system simulation technology.

[0003] Existing scenario simulation systems all render and simulate single-person operations. However, in reality, there are often situations where multiple people need to operate the same scene together. Virtual scenario simulation in such cases inevitably requires multiple people to operate in different spaces within the same simulation scene. This technology for multi-person VR simulation has not yet been solved.

[0004] Furthermore, even though the simulation technology for multiple people operating in different spaces within the same simulation scenario has been solved, the large amount of data rendered in TPCast wireless video transmission (3K, 120 frames per second) necessitates the use of a 5G network to handle its bandwidth. However, the large data volume and narrow channel range of 5G signals can easily cause frequency hopping interference between signals in different spaces. Therefore, the maximum number of channels per unit space can only be two. When three or more channels are operating simultaneously, anti-interference shielding measures must be implemented to prevent interference from causing the transmitter and receiver to lose connection. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a scenario simulation system to prevent signal interference. This system comprises a scenario simulation training room consisting of a scenario simulation signal shielding space and a virtual simulation system. The scenario simulation signal shielding space includes side walls, a top plate, and a floor. The side walls include a substrate and a first alloy cloth layer, a copper mesh, and a second alloy cloth layer sequentially disposed on the substrate. Outside the second alloy cloth layer are a metallic paint layer and an outer paint layer, respectively. The substrate, the first alloy cloth layer, the copper mesh, and the second alloy cloth layer are bonded together with adhesive.

[0006] Optionally, the sidewall has a pipe connected to the outside of the scenario simulation signal shielding space, and the pipe is covered with an electromagnetic shielding material layer.

[0007] Optionally, the floor surface has an anti-electromagnetic material layer.

[0008] Optionally, a door is provided on the side wall, and a curtain is hung above the door to cover the surface of the door, the curtain being an electromagnetic interference shielding mesh.

[0009] Optionally, the curtain has a clamping element on the side near the floor to seal the gap between the curtain and the floor.

[0010] Optionally, the sidewall is made of plywood, and both the first alloy cloth layer and the second alloy cloth layer are composed of multiple layers of alloy cloth.

[0011] The present invention also provides a scenario simulation training room, which is composed of multiple scenario simulation signal shielding spaces connected together.

[0012] The present invention also provides a scenario simulation system to prevent signal interference. The system is characterized in that each scenario simulation signal shielding space contains a set of independently operating scenario simulation equipment. The host of each independently operating scenario simulation equipment is connected to a central control host located outside the scenario simulation training room via a signal transmission line. The host in the shielding space and the central control host can be opened and closed freely as needed. The host in each independent shielding space outputs rendering signals to the central control host. The central control host integrates the rendering signals of the hosts in multiple independent shielding spaces into the same scene and feeds back the integrated information to the hosts in each independent shielding space, thereby realizing interactive training of multiple people and multiple machines in the same scene.

[0013] Optionally, each scenario simulation device that can operate independently in the scenario simulation signal shielding space includes a head-mounted display, a handheld operating device, a scenario setting handle for selecting scenarios, a host, and a locator. The display, operating device, and scenario setting handle are all equipped with photosensitive sensors to sense the laser information emitted by the locator and transmit the information to the host.

[0014] The process of rendering virtual scenarios of operation actions in each scenario simulation signal shielding space and displaying the scenarios on the display includes: the host calculating the position of the display, operating device or scenario setting handle in the current scenario based on the laser information, and displaying the scenarios on the display.

[0015] Optionally, the central control host of the anti-signal interference scenario simulation system is connected to the external monitoring video. The central control host has a virtual camera embedded in it, which can set the virtual position of the virtual camera as needed, and display the virtual scene centrally integrated by the central control host on the external monitoring video.

[0016] The sidewall of the scenario simulation signal shielding space of the present invention includes a substrate and a first alloy cloth layer, a copper mesh, and a second alloy cloth layer sequentially disposed on the substrate. A metallic paint layer and an outer paint layer are sequentially disposed outside the second alloy cloth layer. The substrate, the first alloy cloth layer, the copper mesh, and the second alloy cloth layer are bonded together with adhesive. Testing has shown that this arrangement achieves excellent signal shielding and electromagnetic interference prevention effects.

[0017] The aforementioned combination of multiple scenario simulation signal shielding spaces forms a scenario simulation room, which, together with a server, constitutes a scenario simulation system. Within each scenario simulation signal shielding space, operational actions are rendered as a virtual scenario for display on the monitor. Simultaneously, each scenario simulation signal shielding space outputs rendering signals to the server, which then integrates these signals into a single scene and feeds them back to the monitor in each scenario simulation signal shielding space.

[0018] Due to the excellent electromagnetic interference protection effect of the scenario simulation signal shielding space of this invention, users in this scenario simulation system can see the current scenario screen and the position of the operating device in the scenario through a display worn on the head, and at the same time see the actions of operators in other scenario simulation signal shielding spaces in the scenario screen.

[0023] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise ratios, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0024] This invention provides a scenario simulation signal shielding space, such as... Figure 1 As shown, the space includes side walls 2, a top plate 1, and a floor 3. Figure 2 As shown, the sidewall 2 includes a substrate 200 and a first alloy cloth layer 210, a copper mesh 220 and a second alloy cloth layer 230 sequentially disposed on the substrate 200. On the outside of the second alloy cloth layer 230, there are a metallic paint layer 240 and an outer paint layer 250 in sequence. The substrate 200, the first alloy cloth layer 210, the copper mesh 220 and the second alloy cloth layer 230 are bonded together with adhesive 300.

[0025] In addition, in the actual operation of the side wall 2 construction, the width of the first alloy cloth layer 210 and the second alloy cloth layer 230 is only 1m. The two alloy cloths need to be overlapped and the edge treatment is required. The width is at least 10cm, and the construction thickness is more than 4 layers. The amount of metallic paint layer 240 used is more than 6 square meters / kg.

[0026] like Figure 1 As shown, the side wall 2 has a pipe 4 connected to the outside of the scenario simulation signal shielding space, and the pipe 4 is covered with an electromagnetic shielding material layer 41. The exhaust pipe is wrapped with an electromagnetic shielding material layer 41, with a wrapping thickness of not less than 4 layers and a wrapping length greater than 1m.

[0027] The surface of the floor 3 has an anti-electromagnetic material layer 31. The use of anti-electromagnetic material for the floor (no treatment is required if there is no basement on the first floor) effectively prevents signals from escaping from the floor.

[0028] See also Figure 1 A door 300 is provided on the side wall 2. Above the door 300, a curtain 310 is hung to cover the surface of the door 300. The curtain 310 is made of electromagnetic interference shielding mesh fabric. A clamping member 320 is provided on the side of the curtain 310 closest to the floor 3 to seal the gap between the curtain 310 and the floor 3. The curtain 310 covers the surface of the door 300 using electromagnetic interference shielding mesh fabric, with a thickness of not less than four layers, and there should be no gaps between the clamping member 320 and the floor 3.

[0029] In this embodiment, the sidewall 2 is made of plywood, and the first alloy cloth layer 210 and the second alloy cloth layer 230 are both composed of multiple layers of alloy cloth.

[0030] The present invention also provides a scenario simulation room 1000, such as Figure 3 As shown, it is composed of multiple scenario simulation signal shielding spaces connected together.

[0031] This invention also provides a scenario simulation system, such as Figure 3 As shown, it is used in a scenario simulation room 1000 and a server 2000 as described above. Each scenario simulation signal shielding space in the scenario simulation room 1000 has a display 10. In each scenario simulation signal shielding space, the operation actions are rendered into a virtual scenario for display on the display 10. At the same time, each scenario simulation signal shielding space outputs the rendering signal to the server 2000. The server 2000 integrates the rendering signal into the same scene and feeds it back to the display 10 of each scenario simulation signal shielding space.

[0032] Figure 4 A schematic diagram of the internal structure of the signal shielding space for each scenario simulation. For example... Figure 4 As shown, each scenario simulation signal shielding space includes a head-mounted display 10, a handheld operating device 20, a scenario setting handle 30 for selecting law enforcement scenarios, a host 40, and a locator 50. The display 10, operating device 20, and scenario setting handle 30 are all equipped with photosensitive sensors 100 to sense the laser information emitted by the locator 50 and transmit the information to the host 40.

[0033] The process of rendering virtual scenarios of operational actions in each scenario simulation signal shielding space and displaying these scenarios on the display 10 includes: the host 40 calculating the positions of the display 10, operating device 20, or scenario setting handle 30 in the current scenario based on laser information, and displaying the scenarios on the display 10. At this time, the user can see the current scenario and the position of the operating device 20 in the scenario through the head-mounted display 10, and simultaneously see the actions of operators in other scenario simulation signal shielding spaces within that scenario.

[0034] In this embodiment, the scenario simulation system further includes a monitoring device. Each scenario simulation signal shielding space has a video recorder for recording the actual actions in each scenario simulation signal shielding space and displaying them centrally on the monitoring device.

[0035] In addition, the doors 300 of each scenario simulation signal shielded space are controlled by facial recognition access control. Users can register their facial information into the system and bind it to their accounts at the access control point, and then control the opening of the door and login to the system through facial recognition. Moreover, operators can also wirelessly connect to the server 2000 via their mobile phones to remotely view the operation videos and operation steps recorded on the server 2000, watch the playback, correct errors, and learn how to handle them.

[0036] The sidewall of the scenario simulation signal shielding space of the present invention includes a substrate and a first alloy cloth layer, a copper mesh, and a second alloy cloth layer sequentially disposed on the substrate. A metallic paint layer and an outer paint layer are sequentially disposed outside the second alloy cloth layer. The substrate, the first alloy cloth layer, the copper mesh, and the second alloy cloth layer are bonded together with adhesive. Testing has shown that this arrangement achieves excellent signal shielding and electromagnetic interference prevention effects.

[0037] The aforementioned combination of multiple scenario simulation signal shielding spaces forms a scenario simulation room, which, together with a server, constitutes a scenario simulation system. Within each scenario simulation signal shielding space, operational actions are rendered as a virtual scenario for display on the monitor. Simultaneously, each scenario simulation signal shielding space outputs rendering signals to the server, which then integrates these signals into a single scene and feeds them back to the monitor in each scenario simulation signal shielding space.

[0038] Due to the excellent electromagnetic interference protection effect of the scenario simulation signal shielding space of this invention, users in this scenario simulation system can see the current scenario screen and the position of the operating device in the scenario through a display worn on the head, and at the same time see the actions of operators in other scenario simulation signal shielding spaces in the scenario screen.

[0039] Obviously, those skilled in the art can make various modifications and variations to the invention without departing from the spirit and scope of the invention. Therefore, if these modifications and variations fall within the scope of the claims of the invention and their equivalents, the invention is also intended to include these modifications and variations.
