Description

Technical Field

[0001] The present invention relates to the field of advertising display equipment, in particular to a holographic advertising machine that displays 3D animation in a spherical stereoscopic manner based on the principle of human visual persistence, and can realize multi-angle stereoscopic advertising display. Background Art

[0002] Currently, most 3D animation holographic advertising machines on the market use two vertically mounted light panels to generate three-dimensional animations through the principle of human visual persistence. Although this technology can achieve three-dimensional display from front, back, left and right perspectives, it has obvious limitations: when looking down from the top of the device, no image can be seen because there is no light panel installed on the top, resulting in limited display effects. In order to solve this problem, the present invention proposes a holographic advertising machine with an arc-shaped light panel design, which can generate a 360-degree three-dimensional animation display in the horizontal direction, overcoming the display blind spot of existing devices at the top-down angle, and at the same time, there is no display image in the bottom area.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5 As shown, a technical solution provided by the present invention is:

[0030] Embodiment 1: Stereoscopic animation display based on the principle of human vision persistence

[0031] The present invention is based on the principle of human visual persistence. The high-density LED lamp beads on the arc-shaped lamp board flash at a frequency of 50-60Hz, and the brushless motor assembly drives the lamp board to rotate at a speed of 1500 revolutions per minute, thereby utilizing the visual retention effect of the human eye to generate 360-degree stereoscopic animation in the horizontal direction. This design can adapt to different animation content requirements by adjusting the rotation speed and the flashing frequency of the lamp beads to ensure smooth and clear images.

[0032] Example 2: Design and advantages of curved light panels

[0033] The bending angle of the arc light board is greater than 180 degrees but less than 360 degrees. The number of LED lamp beads will vary according to the specific curvature. For example, when the bending angle of the arc light board is 300 degrees, 384 LED lamp beads are evenly distributed on the light board, and the distance between the lamp beads is 0.02 mm; if the bending angle is reduced to 270 degrees, the number of LED lamp beads will be reduced to 345; when the bending angle of the arc light board is 180 degrees, the number of lamp beads is 230, ensuring that the distance between the lamp beads remains consistent and the display effect is uniform.

[0034] This design not only overcomes the display blind spot problem of existing vertical light panels, but also ensures that the complete three-dimensional animation effect can be observed from all directions such as the top and the side. In this embodiment, the outer cover of the equipment is made of acrylic material (PMMA), which has excellent optical transparency (light transmittance of 92%), which can ensure that the light propagation of the internal LED light panel is not affected. In addition, acrylic material is lighter than glass and has strong impact resistance, which can provide good protection for internal components while maintaining the overall lightness and durability of the equipment. Acrylic also has good weather resistance and is suitable for various indoor and outdoor advertising display scenarios.

[0035] Example 3: Implementation of control system module

[0036] The control system module (16) is composed of two parts, hardware and software. The hardware part includes a central processing unit (CPU), a storage unit (RAM and ROM), an input and output interface (I / O) and a wireless communication module (WiFi module and 5G network module).

[0037] Central Processing Unit (CPU): This module uses a high-performance, low-power embedded processor, such as the ARM Cortex-M4 processor, which has a main frequency of 72MHz, supports floating-point operations, has excellent real-time response capabilities, and can quickly handle the switching of animation content and the parsing and execution of voice recognition instructions.

[0038] Storage unit: The system has built-in 512KB Flash storage for storing firmware, system settings and speech recognition vocabulary. 128KB RAM (random access memory) is used for data storage during runtime, including current animation content cache, device operation records, etc.

[0039] Input / output interface (I / O): The I / O interface includes a PWM control interface for connecting to the LED light board, a GPIO interface for controlling the motor rotation, and a connection interface with a microphone and external devices such as HDMI and WiFi modules. The input sampling rate of the microphone is 16kHz, which can ensure high-precision processing of speech recognition.

[0040] Wireless communication module: The integrated WiFi module complies with the IEEE 802.11b / g / n standard and provides a transmission rate of up to 150Mbps. The 5G communication module is based on Qualcomm Snapdragon X55 and supports the 5G NR standard, enabling large-scale MIMO, low-latency and high-bandwidth data transmission. The module ensures a stable connection between the device and the mobile phone or computer APP and low-latency data communication for remote cluster control.

[0041] Example 4: Remote cluster control of 5G network

[0042] The device's 5G network module (11) implements data communication through a standard TCP / IP protocol stack, ensuring the stability and consistency of synchronous playback of animation content on multiple devices.

[0043] Data synchronization mechanism: The 5G network module uses a communication protocol based on the timestamp synchronization mechanism, and ensures that the time of the device and the cloud server is synchronized through NTP (Network Time Protocol). The cloud server sends a unified time signal through broadcasting, and all devices calibrate their local clocks through the received timestamps.

[0044] Buffer design: In order to cope with possible network delays between devices, each device sets a 500ms buffer when playing animation content. This buffer ensures that the device can achieve continuous and smooth playback even if there is slight network jitter during data transmission.

[0045] Network packet loss recovery mechanism: The 5G network module adopts a fast retransmission mechanism. Once the loss of UDP data packets is detected, the device will reconstruct the lost data packets through redundant data check codes, or immediately request the server to resend key data packets to ensure that there will be no obvious freezes or interruptions during playback due to data loss.

[0046] Synchronization delay control: By dynamically adjusting the sending interval and bandwidth utilization of UDP packets, the 5G network module can control the synchronization delay between devices to within 10 milliseconds, achieving millisecond-level synchronized animation playback effects between devices. Even in complex network environments, devices can always stay synchronized.

[0047] Example 5: Multifunctional interface and data transmission

[0048] The holographic advertising machine of the present invention is provided with a plurality of interfaces on the base (1), namely a DC power interface (2), an optical fiber interface (3), an HDMI interface (4) and an infrared receiver (5), wherein: the DC power interface (2) is used to power the device, and the input voltage is 12V; the optical fiber interface (3) and the HDMI interface (4) are used to transmit and receive animation data with an external device in real time; the infrared receiver (5) is used to receive a remote control signal. In addition, the TF memory card slot (18) of the device is used to store animation data, and the user can store pre-edited animation content in the memory card and play it through the control system module (6).

[0049] Example 6: Multi-angle 360-degree stereoscopic advertising display

[0050] The holographic advertising machine is mainly used in commercial advertising display scenes, such as shopping malls, exhibitions, stations, etc. The device flashes at a frequency of 50-60Hz through the LED chips on the arc-shaped light board, and forms a 360-degree stereoscopic animation through a rotation speed of 1500 revolutions per minute. Advertisers can edit the advertising content in advance and store it in the TF card slot of the device. The advertising machine automatically reads and plays these contents after startup.

[0051] In actual applications, the advertising machine can connect to the WiFi network in the mall through a remote control module. The mall managers can change the playback content in real time through a computer or mobile phone APP to ensure synchronization with holiday promotions, product updates and other activities.

[0052] Practical application scenarios:

[0053] After installing the holographic advertising machine in the atrium of the shopping mall, advertisements can be displayed from any angle. Especially during festivals, product promotion animations can be played, such as 3D gift boxes, jumping brand logos, etc., to attract customers' attention.

[0054] Example 7: Implementation of voice recognition control system

[0055] The device's built-in control system module supports voice recognition. In some occasions where the advertising content needs to be changed quickly, such as product launches or temporary promotions, users can directly control the holographic advertising machine through voice commands, such as "start playing new product animation" or "stop playing the current animation." When the device receives a voice command, the control system will analyze the command through the voice recognition module and instantly switch to the pre-set animation content.

[0056] Practical application scenarios:

[0057] In outdoor advertising or auto show displays, staff can remotely control the holographic advertising machine through voice commands without the need for a remote control or mobile phone APP. Especially when displaying interactive advertisements, voice recognition can achieve instant changes in the advertising display content through simple voice commands. For example, when the user says "show wheel details", the advertising machine will immediately switch to a 3D animation showing the car wheels, thereby improving the display effect.

[0058] Example 8: Practical application of 5G network remote cluster control

[0059] Multiple holographic advertising machines can be remotely and synchronously controlled through the 5G network module. For example, in a chain store, managers can use a master control device to control all holographic advertising machines in the mall at the same time, playing the same or different animation content. Each device maintains a synchronous connection with the main server through the 5G network to ensure that the playback content of all devices is consistent.

[0060] Practical application scenarios:

[0061] A chain brand's advertising machines are distributed in shopping malls in different cities. The management team can switch the advertising content of all shopping malls in a short time through the remote cluster control system. For example, when a brand launches a new product, the brand can send instructions through the main server to synchronously play 3D animations to display the new product, thereby achieving nationwide advertising synchronization.

[0062] Example 9: Customized 3D animation editing and display

[0063] Users can connect the device through a mobile phone APP or computer software and customize the content of the spherical stereoscopic animation. For example, users can design a 360-degree rotating brand logo animation through the built-in animation editing software, and then import it into the control system module of the holographic advertising machine. Users can choose to customize the animation's playback speed, rotation angle, color and other parameters to meet personalized display needs.

[0064] Practical application scenarios:

[0065] At exhibitions or company product launches, companies can design customized 3D stereoscopic animations, such as a company logo rotating in a 3D sphere, or a product 3D model being gradually decomposed and assembled. Through the device's APP, managers can adjust the animation playback effect at any time and switch flexibly according to on-site needs, greatly improving the interactivity and technological sense of the display.

[0066] Example 10: Application of interactive display of multiple devices

[0067] Through the synchronous display function in the control system module, multiple holographic advertising machines can be connected through the 5G network and interact with each other. For example, in a large exhibition or shopping mall, users can set different holographic advertising machines to play different content, but when certain conditions are met, such as a device being touched by a person, all devices can switch to interactive animation mode at the same time to form a coherent display effect.

[0068] Practical application scenarios:

[0069] In a large shopping mall, several holographic advertising machines display different product information, but when a customer approaches or touches one of the devices, all the devices will automatically switch to the 3D display mode of the same product. For example, when a customer approaches a device displaying clothing, all the devices will switch to display the latest season of the brand's 3D animation show at the same time, creating a linkage display effect of multiple devices.

[0070] Example 11: Automatic detection and maintenance function

[0071] The control system of the equipment has an automatic detection function. When the equipment is running, the control system will monitor the status of each module, such as power supply, motor, LED light board, 5G network connection, etc. If a module is abnormal, the equipment will automatically send an alarm message to the manager's mobile phone APP and generate a maintenance report. Users can view detailed fault information by remotely logging into the equipment background, so as to arrange maintenance in time.
