Description

Technical Field

[0002] With the rapid development of the catering industry and the increasing demand of consumers, the automation and intelligence of restaurant services have become an important trend in the industry upgrade. As an important part of this, self-service ordering can not only effectively improve the service efficiency of the restaurant and reduce human resource costs, but also provide consumers with a more convenient and personalized dining experience.

[0003] At present, the mainstream self-service ordering method on the market is to scan the QR code on the table with the customer's mobile phone to enter the ordering system. Although this method has achieved self-service to a certain extent, it also has many technical limitations.

[0004] First, the small display page is an obvious disadvantage of this method. Due to the size limitation of mobile phone screens, the ordering page often cannot display rich information about dishes, such as pictures, detailed descriptions, etc. This results in consumers not being able to fully understand the characteristics and taste of dishes when ordering, which can easily lead to confusion and misunderstanding. And due to the limitations of screen size and interaction methods, traditional self-service ordering systems can often only display limited information about dishes, with less content displayed, and cannot fully demonstrate the characteristics and advantages of the restaurant. This not only affects consumers' ordering experience, but also limits the dissemination and promotion of restaurant brands.

[0005] Secondly, scanning code ordering is highly technology-dependent. It requires customers to have a smartphone and the phone needs to have the corresponding ordering app installed or scan the QR code. If customers do not have a smartphone or are unwilling to use the mini program, they will not be able to use the scan code ordering service, affecting their dining experience.

[0062] like Figure 1-6 As shown, the utility model provides a food ordering system, comprising: a dining table 1 and a holographic optical display device 2 installed on the dining table 1; a groove 101 is provided on the dining table 1, and the holographic optical display device 2 is arranged in the groove 101; wherein: the holographic optical display device 2 comprises a holographic display module 219, a gesture sensing module 201 and a holographic glass 202; the holographic display module 219 is electrically connected to the gesture sensing module 201, and the holographic glass 202 is arranged on the holographic display module 219; a holographic image is embedded in the holographic glass 202, and the holographic image is reconstructed on the dining table 1 through the holographic display module 219.

[0063] The ordering system of the utility model comprises a dining table 1 and a holographic optical display device 2. The holographic optical display device 2 is arranged in a groove 101 of the dining table 1. The holographic imaging technology of the holographic display module 219 is used to form an image identical to the holographic image on the other side of the holographic glass 202, so as to realize the reconstruction of the holographic image on the dining table 1. The gesture sensing module 201 captures the gestures and movements of the customer, and converts the captured gestures and movements into electronic signals and sends them to the holographic display module 219 for analysis and processing, so that the customer can directly operate and select on the dining table 1, thereby realizing It realizes the rich display of interactive interfaces in a larger space, making the holographic image display more three-dimensional, intuitive, real and comprehensive. Customers can fully understand the characteristics and advantages of the restaurant and realize human-computer functional interaction through the gesture sensing module 201. They can order food without using mobile phones or other devices to scan codes and do not need to provide personal information. It creates an immersive dining experience, reduces the risk of information leakage, better protects the privacy and security of customers, saves customers' time, and allows customers to enjoy a visual feast while dining, thereby enhancing the restaurant's image and competitiveness, and can be applied to a variety of scenarios.

[0064] It should be noted that the ordering system of the utility model is a hardware system, and each of its internal components is also a hardware component. On this basis, some existing software or programs are used to realize functions such as analysis and processing of electronic signals and control, thereby realizing the holographic display and interactive technology of the ordering system. However, the utility model itself does not involve any software technology update.

[0065] In this embodiment, holographic imaging technology is a technology that uses the principles of interference and diffraction to record and reproduce the real three-dimensional image of an object. The so-called "hologram" means "all information", which means that all information of the light emitted by the photographed object is recorded and reproduced by projection. Holographic imaging technology is generally also called virtual imaging technology or holographic imaging. Its imaging principle is to record the phase and amplitude of the object's light wave by means of light wave interference. At the same time, the light wave information of the object is displayed by means of the diffraction principle, so as to achieve the imaging effect.

[0066] In this embodiment, if Figure 6 As shown, holographic glass 202 is also called holographic image glass (also called holographic mirror glass), which is a branch product of laminated glass formed by a transparent holographic film. It uses holographic grating technology to print holographic patterns on the film, which can be customized according to needs or choose the manufacturer's existing holographic patterns. Under the illumination of light, the holographic image can present different holographic effects from different angles, which can be three-dimensional or flat, and can show different colors and textures according to different angles of light. It is a modern high-tech glass product with high transparency, excellent optical properties, beautiful appearance, high hardness and other characteristics.

[0067] In this embodiment, in the holographic glass 202, the holographic image is embedded in the glass in the form of specific interference fringes or structures. When the light source shines on these fringes or structures, interference and diffraction of light will occur, thereby reproducing the three-dimensional image of the original object.

[0068] In this embodiment, the holographic image includes but is not limited to: interactive screens for ordering needs in the catering industry, interactive screens for children's learning and entertainment, interactive screens for restaurant culture, interactive screens for counter operations, etc., which can be customized according to the actual use scenario, and the holographic imaging technology of the holographic display module 219 is used to realize multi-screen switching display. In this way, the ordering system of the utility model uses holographic imaging technology to present the dishes on the menu to customers in 3D form, so that they can see the appearance and details of the dishes more directly. This intuitiveness can help customers better understand the ingredients and cooking methods of the dishes, and cooperate with the gesture sensing module 201 to realize human-computer interaction, which can create an immersive dining experience, allowing customers to be more involved and enjoy the dining process. Holographic imaging technology can also create a variety of unique scenes and atmospheres, allowing customers to feel more fun and surprises when dining. For example, restaurants can create different scenes through holographic imaging technology according to different festivals or themes, so that customers can enjoy a visual feast while dining, provide customers with more personalized services, and enhance customers' cognition and favorability of restaurants. In addition, the ordering system of the utility model uses holographic imaging technology to update dish information, prices, etc. in real time, reducing the cost of replacing and updating paper menus. At the same time, the combination of holographic display technology and gesture interaction function reduces the workload of waiters, increases the speed of ordering, allows customers to enjoy food faster, and improves the operating efficiency of the restaurant.

[0069] In this embodiment, if Figure 3 As shown, the ordering system further includes a power supply device 3, which is electrically connected to the holographic optical display device 2 to provide a voltage signal to the holographic optical display device 2, wherein the voltage signal includes but is not limited to: 12V, 24V, 36V, etc. Figure 3 The principle of the ordering system is explained. After the holographic optical display device 2 receives the power signal provided by the power supply device 3, it performs a power-on action. At this time, the ordering system is activated. The holographic display module 219 uses holographic imaging technology to form an image identical to the holographic image on the other side of the holographic glass 202 to achieve reconstruction of the holographic image on the dining table 1. A holographic image display area is formed on the table top of the dining table 1. The gesture sensing module 201 is combined to capture the customer's gestures and movements in the holographic image display area, and convert them into electronic signals and send them to the holographic display module 219 for analysis and processing to obtain the customer's ordering information, thereby providing services to the customer, creating an immersive dining experience, reducing the risk of information leakage, better protecting the customer's privacy and security, saving the customer's time, and allowing the customer to enjoy a visual feast while dining, thereby enhancing the restaurant's image and competitiveness, and being applicable to a variety of scenarios.

[0070] In this embodiment, if Figure 2As shown, the holographic optical display device 2 further includes a V-shaped bracket 203, and the holographic display module 219, the gesture sensing module 201 and the holographic glass 202 are all arranged on the V-shaped bracket 203. In this way, the holographic optical display device 2 is installed and fixed in the groove 101 of the dining table 1 through the V-shaped bracket 203.

[0071] In this embodiment, if Figure 2 As shown, the holographic display module 219 includes: a control mainboard 204, a display screen 205, and an interface adapter board 206. The control mainboard 204 is electrically connected to the display screen 205 and the interface adapter board 206. The display screen 205 can be a high-brightness TFT display screen.

[0072] In this embodiment, if Figure 2 As shown, the display screen 205 includes a display panel 2051, a panel bracket 2052 and a shading strip 2053. The display panel 2051 is mounted on the V-shaped bracket 203 through the panel bracket 2052. A plurality of LED light sources are arranged on the display panel 2051, and the shading strip 2053 is arranged at the edge of the display panel 2051. The display panel 2051 is fixed on the panel bracket 2052, and the panel bracket 2052 is mounted on the right side of the V-shaped bracket 203 by screws. When the LED light source is irradiated on the holographic image, interference and diffraction effects will be generated with the interference fringes recorded on the holographic image. These interference fringes are actually the encoding of the light wave information of the object being photographed, which contains information such as the size, shape, brightness and contrast of the object. In the process of interference and diffraction, the light of the LED light source is modulated by the holographic image, and the light wave is reconstructed to reconstruct the information of the original object light wave. This process is similar to the decoding process of the light wave, and the information stored in the interference fringes is restored. After interference and diffraction, the reconstructed light waves will form a three-dimensional image in space. This image is visually very similar to the original object and has a real sense of three-dimensionality and depth, so that the holographic image is projected on the dining table 1 and combined with the gesture sensing module 201 to capture the customer's gestures and movements to complete the ordering operation.

[0073] In this embodiment, if Figure 2As shown, the purpose of setting the shading strip 2053 at the edge of the display panel 2051 is mainly to improve the visual quality of the holographic image, avoid light pollution, protect the display panel 2051 and enhance the customer experience. When the LED light source directly illuminates the holographic image, especially at the edge, unnecessary scattering or halo may be generated, thereby interfering with the clarity or fidelity of the holographic image. By setting the shading strip 2053 at the edge of the display panel 2051, this part of the scattered light can be effectively blocked, thereby improving the visual quality of the holographic image. The shading strip 2053 can reduce the stray light at the edge, help to improve the contrast between the holographic image and the background, and make the holographic image clearer and more prominent. In addition, in some cases, if the LED light source is too strong or not properly controlled, light pollution may occur, which not only affects the display effect of the holographic image, but also may cause discomfort to the customer's eyes. The shading strip 2053 can effectively limit the radiation range of the LED light source and avoid the occurrence of light pollution. Secondly, the shading strip 2053 can also protect the display panel 2051 from being irradiated by excessively strong light at the edge, thereby extending the service life of the display panel 2051. Finally, the shading strip 2053 can eliminate edge halo, improve contrast, and avoid light pollution, thereby improving the customer's experience in viewing the holographic image, thereby improving the customer's dining experience.

[0074] In this embodiment, an optical machine may be further provided on the display panel 2051 as a light source.

[0075] In this embodiment, if Figure 1-5 As shown, the holographic image is reproduced on the holographic glass 202 through the LED light source of the holographic display module 219. After the light passes through the holographic glass 202 with a special structure, it is gathered again at the same distance on the other side of the holographic glass 202 to achieve light field reconstruction and form an image identical to the original. The position of the formed image is shown in FIG. Figure 4 , 5 shown.

[0076] In this embodiment, if Figure 2 As shown, the holographic glass 202 is mounted on the top surface of the V-shaped bracket 203 through a fixing assembly; the fixing assembly includes a glass cover plate 207, a first mounting bracket 208, and a second mounting bracket 209; wherein the holographic glass 202 is mounted on the glass cover plate 207, the glass cover plate 207 is mounted on the first mounting bracket 208 through a backing adhesive 210, and the first mounting bracket 208 is fixed to the top surface of the V-shaped bracket 203 through the second mounting bracket 209. The gesture sensing module 201 is mounted on the second mounting bracket 209 and is electrically connected to the control mainboard 204. The gesture sensing module 201 recognizes and understands the customer's gestures and movements, and converts them into electronic signals for transmission to the control mainboard 204.

[0077] In this embodiment, if Figure 2 As shown, the control mainboard 204 is installed on the V-shaped bracket 203 through the mainboard bracket 211. After the holographic optical display device 2 receives the power signal, it performs the power-on action, at which time the ordering system is activated. One minute later, the system orders normally. When the control mainboard 204 controls the LED light source on the display panel 2051 to illuminate the holographic image of the holographic glass 202, it will produce interference and diffraction effects with the interference fringes recorded on the holographic glass 202. The mirror surface of the holographic glass 202 is reflected multiple times, and finally at the same distance on the other side of the holographic glass 202, the light field is reconstructed, and the imaging is focused to reproduce the same three-dimensional image of the original object, as shown in FIG. Figure 4 , 5 As shown, the holographic image is projected on the dining table 1, and combined with the gesture sensing module 201, the customer's gestures and movements are captured, and converted into electronic signals and sent to the control motherboard 204. The control motherboard 204 analyzes and processes the received electronic signals to obtain the ordering information and generate an order, and sends the generated order to the external device 4.

[0078] In this embodiment, if Figure 2 As shown, the gesture sensing module 201 includes a gesture sensing sensor and an image processor connected to the gesture sensing sensor. The gesture sensing sensor is used to capture the customer's gestures and movements. The gesture sensing sensor includes but is not limited to: an infrared sensor, a capacitive sensor, an optical camera, etc. Among them, the infrared sensor detects the customer's approach and position change by emitting and receiving infrared rays. The capacitive sensor detects gestures and touch actions by measuring changes in capacitance. The optical camera recognizes gestures and actions by capturing and analyzing images. The image processor processes and analyzes the data from the gesture sensing sensor to recognize and understand the customer's gestures and movements, and converts them into electronic signals for transmission to the control motherboard 204.

[0079] In this embodiment, if Figure 2As shown, the interface adapter board 206 is installed on the V-shaped bracket 203 through the adapter board bracket 212, and the interface adapter board 206 is provided with an external data interface 2061, and the signal on the control main board 204 is transmitted to the external device 4 through the external data interface 2061 on the interface adapter board 206. The external device 4 is connected to the holographic optical display device 2. The control main board 204 analyzes and processes the received electronic signal to obtain the order information and generate an order, and sends the generated order to the external device 4, which includes but is not limited to: a background computer, a kitchen display device, a printing device, etc. After receiving the order information, the external device 4 implements the meal preparation operation and notifies the kitchen staff to complete the cooking of the dishes involved in the order. After the cooking is completed, the cooking information is fed back through the external device 4 and clicked to complete, thereby realizing the closed-loop operation of the entire ordering system. Exemplarily, the order information is sent to the background computer, and the staff can view and update the order status at any time. The order information is sent to the kitchen display device for real-time display, and the chef can prepare and cook dishes according to the information on the kitchen display device. Send the order information to the printing device for printing for the chef's reference.

[0080] In this embodiment, if Figure 2 As shown, the external data interface 2061 includes multiple types of interfaces, including but not limited to: HDMI interface (High Definition Multimedia Interface), USB interface, network interface, AV interface (composite video interface), S-Video interface (four-pin video interface), audio interface, etc. In this way, the communication between the holographic optical display device 2 and different external devices 4 can be realized to adapt to restaurant management systems in different scenarios.

[0081] In this embodiment, if Figure 2As shown, the holographic display module 219 also includes a cooling fan 213, which is electrically connected to the control mainboard 204. The cooling fan 213 is mounted on the V-shaped bracket 203, and the control mainboard 204 creates a realistic 3D holographic projection effect by controlling the rotation speed of the cooling fan 213 and the flashing speed of the LED light source. Specifically, the LED light source is used to illuminate the holographic image. A holographic image is a special image that records the light wave information of an object. When the holographic image is illuminated by light waves, the original light waves can be reproduced due to the diffraction principle to form a realistic three-dimensional image of the original object. The cooling fan 213 is usually attached with a medium that can reflect or transmit the holographic image. When the cooling fan 213 rotates, the holographic image also moves rapidly. The LED light source flashes at a specific frequency, which matches the rotation speed of the cooling fan 213. When the LED light source is on, it illuminates a part of the holographic image, and then illuminates the rest of the holographic image as the LED light source goes out and the fan rotates. When human eyes observe things, it takes a short period of time for light signals to be transmitted to the brain nerves. After the light effect ends, the visual image does not disappear immediately. This residual vision is called "afterimage", and this visual phenomenon is called "persistence of vision". When the LED light source flashes quickly and illuminates the rotating holographic image, due to the persistence of vision effect, the human eye sees a continuous, three-dimensional image instead of a series of rapidly switching two-dimensional images, such as Figure 5 The cooling fan 213 can also play a role in heat dissipation to ensure the normal use of the holographic optical display device 2.

[0082] In this embodiment, if Figure 1 , 4 As shown, the dining table 1 is provided with a plurality of grooves 101 for mounting the holographic optical display devices 2; the number of the grooves 101 matches the number of the holographic optical display devices 2. In this way, multiple groups of holographic images can be displayed on the dining table 1 to enable multiple people to order and interact.

[0083] In this embodiment, if Figure 1 As shown, the dining table 1 is also provided with a tabletop glass 102. The customer can clearly see the holographic image reconstructed on the holographic glass 202 through the tabletop glass 102, and realize human-computer interaction in combination with the gesture sensing module 201.

[0084] In this embodiment, if Figure 2 As shown, the right side of the V-shaped bracket 203 is provided with a first cover plate 214, the left side of the V-shaped bracket 203 is provided with a second cover plate 215, the front side of the V-shaped bracket 203 is provided with a third cover plate 216, and the rear side of the V-shaped bracket 203 is provided with a fourth cover plate 217. Figure 2 The panel bracket 2052 is fixedly mounted on the first cover plate 214, and the adapter plate bracket 212 is fixedly mounted on the second cover plate 215. A bottom plate 218 is disposed on the bottom surface of the V-shaped bracket 203.

[0085] In this embodiment, if Figure 1 , 4 As shown, the size of the holographic optical display device 2 is 341 mm x 311 mm x 93 mm, and different sizes can be customized depending on different products.

[0086] The ordering system of the utility model comprises a dining table 1 and a holographic optical display device 2. The holographic optical display device 2 is arranged in a groove 101 of the dining table 1. The holographic imaging technology of the holographic display module 219 is used to form an image identical to the holographic image on the other side of the holographic glass 202, so as to realize the reconstruction of the holographic image on the dining table 1.
