Description

Technical Field

[0001] The invention relates to a digital twin simulator, and in particular to an engine digital twin simulator. Background Art

[0002] The engine digital twin simulator can be applied to all aspects of the engine's entire life cycle, including design, manufacturing, testing, and maintenance. Through digital twin simulation, various tests and verifications of the engine can be performed in a virtual environment, reducing the number and cost of physical testing.

[0003] The existing engine digital twin simulator mainly simulates and analyzes the operation process of the engine by displaying a 3D stereoscopic image of the engine on the display screen. When the staff needs to observe the operation process of different parts of the engine, they need to manually rotate the 3D stereoscopic image and change the display angle of the 3D stereoscopic image to observe the operation status of different parts. It is impossible to observe the operation process of multiple parts of the engine at the same time; if you want to observe the operation process of multiple parts of the engine, you need to increase the number of displays to display the operation process of different parts of the engine, but this increases the footprint of the engine digital twin simulator. At the same time, because the 3D stereoscopic image on each display is a flipped engine display image, it is very easy for R&D personnel to be confused about the direction when observing and recording the operation process of the engine, resulting in errors in experimental data or observation data, affecting the accuracy of simulation data. Summary of the invention

[0004] In view of this, the present invention provides an engine digital twin simulator; the purpose is to provide an engine digital twin simulator that can detect and observe multiple parts of the engine at the same time with high accuracy.

[0007] Furthermore, the angles between the plurality of negative refractive flat lenses and the layer plate are all 45 degrees, and the top ends of the plurality of negative refractive flat lenses are all bonded to each other.

[0008] Furthermore, a control panel is provided on the side of the cabinet corresponding to the top of the inspection port.

[0009] Furthermore, a through slot is provided on the side wall of the cabinet at a position corresponding to the control panel, a partition plate is provided in the cabinet at a position corresponding to the through slot, the control panel is penetrated through the through slot, and the control panel is slidably connected to the top surface of the partition plate through a slide rail.

[0010] Furthermore, a display screen and a placement slot are sequentially arranged on the top surface of the control panel from left to right, the display screen is embedded in the top surface of the control panel, the display screen is electrically connected to the controller, an operating keyboard is snap-fitted in the placement slot, and the operating keyboard is electrically connected to the controller.

[0011] Furthermore, a plurality of heat dissipation fans are arranged in the cabinet at positions corresponding to the batteries, and heat dissipation openings are provided on one side wall of the cabinet corresponding to the plurality of heat dissipation fans.

[0012] Furthermore, two symmetrical inspection doors are rotatably arranged in the inspection opening, and the two inspection doors are locked to each other via a locking device.

[0013] Furthermore, handles are provided on two mutually parallel side surfaces of the cabinet, and the two handles are symmetrical to each other.

[0014] The beneficial effects of the present invention are:

[0015] 1. The present invention adopts a combination of a cabinet, a projection screen and an imaging mechanism, so that the staff can transmit digital information to the projection screen through a controller, and the projection screen displays a 3D stereoscopic image of the engine. The 3D stereoscopic image is reflected and projected to the top of the engine digital twin simulator through a negative refractive flat lens. Since the negative refractive flat lens is distributed at a 45-degree angle to the display screen, the 3D stereoscopic image of the engine can only be reflected to the top of the engine digital twin simulator. At the same time, due to the simultaneous reflection of multiple negative refractive flat lenses (due to the special properties of the negative refractive flat lens, it can achieve an imaging effect different from that of a traditional lens, for example: it can produce a distortion-free, high-definition virtual image), when the light generated by the 3D stereoscopic image of the engine displayed on the projection screen is from the positive refractive index material ( When a negative refractive index material (such as air) is incident on a negative refractive index material, a phase inversion occurs on the interface, that is, the wavefront of the incident light becomes convex instead of convex outward. This phase inversion causes the propagation direction of the light in the negative refractive index material to be deflected. After deflection, the light converges above the engine digital twin simulator to form a complete 3D stereoscopic image of the engine. Therefore, the operation process of the engine in all directions is projected onto the top of the engine digital twin simulator to form a three-dimensional projection image of the engine power. Therefore, when observing from various angles, the operation process of the engine components in that direction can be viewed. Therefore, the staff can observe the operation process and operation status of different parts of the engine from multiple angles, thereby reducing the footprint of the present invention and improving the practicability of the present invention and the accuracy of the simulation data.

[0016] 2. The present invention adopts a conical imaging mechanism formed by multiple negative refractive flat lenses set at an angle of 45 degrees to the layer plate, so that when the light generated by the 3D stereoscopic image of the engine displayed on the projection screen is incident from the positive refractive index material (such as air) into the negative refractive index material, the light will undergo a phase reversal at the interface, that is, the wavefront of the incident light becomes convex instead of convex outward. This phase reversal causes the propagation direction of the light in the negative refractive index material to be deflected. After deflection, the light can intersect above the engine digital twin simulator to form a complete 3D stereoscopic image of the engine. Therefore, the operation process of the engine in all directions is projected onto the top of the engine digital twin simulator to form a three-dimensional projection image of the driving force. Therefore, when observing from all angles, the operation process of the engine components in this direction can be viewed, which improves the accuracy of the projection imaging of the imaging mechanism of the present invention, and improves the practicality of the present invention and the accuracy of the simulation data.

[0017] 3. The present invention can also simulate the operation process of the engine under different states and scenarios. When it is necessary to simulate the operation process of the engine, the control panel can be pulled out, and then the controller can be operated through the operation keyboard, and the operation content can be displayed through the display screen, and the image of the simulated engine can be projected to the top of the engine digital twin simulator through the projection screen and the imaging mechanism; at this time, the staff can observe the operation process and operation status of the engine from multiple angles at the same time, simulate the operation of the engine in this state and scenario, record the experimental data, predict the performance and possible failures of the engine according to the experimental data, and optimize the design and operation of the engine according to the simulation results, thereby improving the performance of the engine, and at the same time improving the practicality of the present invention and reducing the number and cost of physical tests.

[0018] 4. The present invention provides a heat dissipation fan and a heat dissipation port at the lower part of the cabinet, so that the present invention can dissipate heat in time when in use, and prevent the electrical components in the cabinet from being damaged by high-temperature overload caused by long-term operation, thereby extending the service life of the electrical components in the cabinet, reducing the operating cost of the present invention, reducing the number of replacement and maintenance times of the present invention, and improving the practicality of the present invention.

[0019] 5. The present invention uses an inspection door to close the inspection port to prevent a large amount of dust from entering the cabinet and affecting the electrical components in the cabinet, thereby increasing the service life of the electrical components, reducing the number of replacement and maintenance times of the present invention, and improving the practicality of the present invention.

[0020] 6. The present invention is provided with handles on both sides, so that workers can move the present invention more conveniently and labor-savingly, thereby improving the usability of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

The negative refractive flat lens is made of a material with a negative refractive index characteristic, and the refractive index of this material is less than zero. It uses the negative refractive index characteristic of the material to change the propagation direction of the light beam. When the light changes from the positive refractive index to the negative refractive index, the negative refractive index of the material is changed. When a negative refractive index material (such as air) is incident on a negative refractive index material, a phase inversion will occur on the interface, that is, the wavefront of the incident light becomes convex instead of convex outward. This phase inversion causes the propagation direction of the light in the negative refractive index material to be deflected, achieving an imaging effect different from that of a positive lens; the imaging mechanism 5 is covered on the projection screen 4, a battery 6 is provided on the inner wall of the bottom surface of the cabinet 1, and a controller 7 is provided above the battery 6 in the cabinet 1, and the controller 7 is a DC direct current and XH2.54 one-to-multiple expansion plug integrated power supply voltage distribution HUB controller of the brand: Anda Control and model: 19019; the battery 6 is a lithium iron phosphate battery of the brand: Lilang and model: LFP-48100-01, the controller 7 is electrically connected to the battery 6, and the projection screen 4 is electrically connected to the controller 7 and the battery 6 respectively.

The above-mentioned negative refractive flat lenses are negative refractive flat lenses produced by Anhui Dongchao Technology Co., Ltd. (the negative refractive flat lenses need to be customized according to the actual usage scenarios); a control panel 8 is arranged above the inspection port on the side of the cabinet 1.

[0031] like Figure 2 As shown, a through slot is provided on the side wall of the cabinet 1 at a position corresponding to the control panel 8, a partition plate 93 is provided in the cabinet 1 at a position corresponding to the through slot, the control panel 8 is penetrated through the through slot, the control panel 8 is slidably connected to the top surface of the partition plate 9 through a slide rail 10, a handle (not shown in the figure) is provided on the outer surface of the control panel 8, and a rebounder (not shown in the figure) may also be provided between the control panel 8 and the inner wall of the through slot.

[0032] like Figure 1As shown, the top surface of the control panel 8 is provided with a display screen 11 and a placement slot from left to right in sequence. The display screen 11 is embedded in the top surface of the control panel 8. The display screen 11 is a high-definition display screen of brand: Texian and model: TX430A-1. The display screen 11 is electrically connected to the controller 7, and an operating keyboard 12 is snap-fitted into the placement slot.

[0033] like Figure 1 As shown, a plurality of cooling fans 13 are arranged at positions corresponding to the batteries 6 in the cabinet 1. The cooling fans are fans of brand: LFFAN and model: LF A220V. A cooling outlet 14 is provided on one side wall of the cabinet 1 corresponding to the plurality of cooling fans 13. A detachable dustproof net is installed on the cooling outlet 14.

[0034] like Figure 2 As shown, two symmetrical inspection doors 17 are rotatably arranged in the inspection port, and a pull groove is provided on the upper portion of the inspection door 17, through which the operator can pull the inspection door 17 open, and the two inspection doors 17 are locked to each other by a locking device 15, and the locking device 15 is a fixed buckle lock of brand: NRH model 6420-25.

[0035] like Figure 2 As shown, handles 16 are provided on two mutually parallel sides of the cabinet body 1. The two handles 16 are symmetrical to each other and are made of metal material.

[0036] The specific working principle is:

[0037] Through the cooperation of multiple sensors, the engine data acquired in real time is converted into processable digital signals, and the digital signals are transmitted to the controller. The digital information analyzed and processed by the controller is transmitted to the projection screen. At this time, a 3D stereoscopic image of the engine is displayed on the projection screen. The 3D stereoscopic image of the engine is reflected and projected to the top of the engine digital twin simulator through a negative refraction flat lens (due to the special properties of the negative refraction flat lens, it can achieve imaging effects different from traditional lenses. For example, it can produce distortion-free, high-definition virtual images). Because the negative refraction flat lens and the display screen (the display screen is embedded in the layer plate) are distributed at a 45-degree angle, and multiple negative refraction flat lenses are provided for simultaneous reflection, that is, when the image appears on the projection screen When the light generated by the 3D stereo image of the engine is incident from a positive refractive index material (such as air) into a negative refractive index material, the light will undergo a phase inversion at the interface, that is, the wavefront of the incident light becomes convex instead of convex outward. This phase inversion causes the propagation direction of the light in the negative refractive index material to be deflected. After deflection, the light converges above the digital twin simulator of the engine to form a complete 3D stereo image of the engine. Therefore, the operation process of the engine in all directions is projected onto the top of the digital twin simulator of the engine to form a three-dimensional projection image of the engine. Therefore, when observing from all angles, the operation process of the engine components in that direction can be viewed. Therefore, the staff can observe the operation process and operation status of different parts of the engine from multiple angles;

[0038] When it is necessary to test and verify the operation process of the engine under different states or scenarios, the control panel can be pulled out, and then the controller can be operated through the operating keyboard to simulate the operation of the engine in various states or scenarios and compare them with the critical values ​​in real time. The operation content and detection values ​​are displayed on the display screen, and the comparison results of the detection values ​​and critical values ​​are displayed. The image of the simulated engine is projected onto the top of the engine digital twin simulator via the projection screen and imaging mechanism. At this time, the staff can observe the operation process and operation status of the engine from multiple angles at the same time, simulate the operation of the engine in this state and scenario, record experimental data, and predict the performance of the engine and possible failures based on the experimental data, and optimize the design and operation of the engine according to the simulation results to improve the performance of the engine.
