Description

Technical Field

[0001] This invention relates to the field of advertising display equipment and related products, specifically a multi-faceted LED cube advertising display device. Background Technology

[0002] As a new type of three-dimensional advertising display equipment, LED cube advertising screens are widely used in public commercial scenarios such as shopping malls, pedestrian streets, exhibitions, and office building lobbies due to their advantages of multi-faceted display, strong three-dimensional viewing, and novel visual effects. Currently, traditional multi-faceted LED cube advertising display devices on the market have simple structures and functions, and most of them adopt a fixed-speed motor drive structure. The rotation speed of the cube screen cannot be dynamically adjusted according to the flow of people on site, which has obvious drawbacks.

[0003] When the display area is crowded, a fixed, low-speed rotation cannot fully utilize the advantages of multi-faceted display, resulting in insufficient advertising exposure and display frequency, thus limiting marketing effectiveness. When the area is sparsely populated or deserted, a fixed, high-speed rotation not only wastes energy but also generates continuous mechanical noise, affecting the environment. Furthermore, the display brightness of traditional LED cube screens is mostly manually adjustable, making it impossible to adapt to changes in natural light and indoor lighting: insufficient brightness in strong light environments leads to blurry and poorly visible advertisements; excessive brightness in low light environments causes glare and light pollution, and prolonged high-brightness operation significantly increases energy consumption and shortens the lifespan of the LED screen.

[0004] In summary, existing LED cube advertising display devices suffer from technical defects such as non-adaptive rotation speed, poor intelligent brightness adaptation, high energy consumption, low scene adaptability, and rigid display effects. They also lack dual intelligent control functions based on pedestrian flow and ambient light, making it difficult to meet the needs of modern commercial advertising for precise display, energy efficiency, and intelligent adaptation. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-faceted LED cube advertising display device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-faceted LED cube advertising display device, comprising a support base, a multi-faceted LED cube screen, an equipment housing, a rotation drive mechanism, and an intelligent sensing and control system. The equipment housing is fixedly embedded in the internal cavity of the support base. The rotation drive mechanism is fixedly installed at the top center of the equipment housing. The power output shaft of the rotation drive mechanism is vertically upward, and the top of the power output shaft is fixedly connected to the bottom center of the multi-faceted LED cube screen, for driving the multi-faceted LED cube screen to rotate around the vertical central axis.

[0007] The intelligent sensing and control system includes a main control module, a people flow detection module, an ambient light detection module, a speed drive module, and an LED dimming drive module; the main control module, the speed drive module, and the LED dimming drive module are all integrated and installed inside the equipment housing; the people flow detection module and the ambient light detection module are fixedly installed on the top outer side of the support base and are electrically connected to the main control module;

[0008] The pedestrian flow detection module is used to collect pedestrian flow density signals in the advertising display area in real time and transmit the collected analog signals to the main control module; the main control module has a built-in pedestrian flow-speed matching algorithm, which outputs the corresponding speed control signal according to the real-time pedestrian flow density, and controls the operating speed of the rotation drive mechanism through the speed drive module;

[0009] The ambient light detection module is used to collect the ambient light intensity signal in real time and transmit the light signal to the main control module. The main control module has a built-in light-brightness matching program, which outputs a brightness adjustment signal according to the real-time ambient light intensity, and adaptively adjusts the display brightness of the multi-faceted LED cube screen through the LED dimming drive module.

[0010] As a preferred embodiment of the present invention, the polyhedral LED cube screen is a regular hexahedral hollow frame structure, with each of the six outer faces of the frame embedded with an independent LED display module. Each LED display module is electrically connected to an LED dimming drive module, which can adjust the display brightness synchronously or independently.

[0011] As a preferred embodiment of the present invention, the rotary drive mechanism includes a servo motor, a reduction gear set, and a rotary support base; the servo motor is fixedly installed inside the equipment housing, the output end of the servo motor is connected to the reduction gear set, the output shaft of the reduction gear set passes through the top plate of the equipment housing and is connected to the rotary support base, and the rotary support base is fixedly connected to the bottom of the multifaceted LED cube screen; the servo motor is electrically connected to the speed drive module, which can realize stepless speed regulation.

[0012] As a preferred embodiment of the present invention, the people flow detection module is an infrared human body sensing sensor array or a high-definition visual recognition camera, which adopts a regional grid detection method to accurately collect and display data on the number of people and their dwell density in the area, and the detection data transmission frequency is not less than 10 times / minute.

[0013] As a preferred embodiment of the present invention, the ambient light detection module is a high-precision photosensitive sensor with a dustproof and light-transmitting protective cover on the sensor surface. The detection light range is 0-10000 lux, which can accurately adapt to different indoor and outdoor lighting scenarios.

[0014] As a preferred embodiment of the present invention, the main control module presets multiple speed adjustment levels and multiple brightness adjustment levels; wherein, the higher the population density, the faster the rotation speed of the multifaceted LED cube screen; when the population density is lower than a preset threshold, the cube screen operates at a low speed or stands still; the higher the ambient light intensity, the higher the display brightness of the LED cube screen; and the brightness is automatically reduced in dark environments to avoid light pollution and energy waste.

[0015] As a preferred embodiment of the present invention, the supporting base is a closed counterweight base, the side wall of the base is provided with heat dissipation grilles and maintenance opening and closing doors, and the inside of the base is provided with shock-absorbing pads to reduce the vibration and noise generated by rotation.

[0016] As a preferred embodiment of the present invention, the device housing also integrates a power supply module and a signal transmission module. The power supply module provides a stable power supply for the entire device, and the signal transmission module supports wireless data transmission and can remotely upload device operation data, advertising playback data, and sensor detection data.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention is the first to propose an intelligent speed control mode based on pedestrian density, abandoning the traditional fixed speed operation mode. When the pedestrian flow is dense, the rotation speed is increased to improve the frequency and coverage of multi-faceted advertising and enhance the advertising and marketing effect; when the pedestrian flow is sparse, the operation speed is low and the system is in standby mode during periods of no traffic, which greatly reduces mechanical wear and power consumption and reduces noise pollution.

[0019] 2. By using a high-precision photosensitive sensor to monitor ambient light in real time and dynamically adjust the brightness of the LED cube screen, the problem of blurry images in strong light and glare in weak light is completely solved, ensuring clear display of advertising images all day long, while effectively reducing ineffective energy consumption and extending the service life of the equipment.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] Please see Figure 1-5 The present invention provides an embodiment of a multi-faceted LED cube advertising display device, the overall structure of which includes a support base 1, a multi-faceted LED cube screen 2, an equipment box 3, a rotation drive mechanism 4, and an intelligent sensing and control system 5.

[0030] The support base 1 is made of thickened metal counterweight material and has a square closed structure. The bottom of the base is equipped with anti-slip and shock-absorbing pads, and the side walls have symmetrical heat dissipation grilles 6 and detachable maintenance doors, which not only ensure the overall stability of the equipment, but also enable heat dissipation of internal components and convenient maintenance.

[0031] The equipment enclosure 3 is fixedly installed in the internal cavity of the support base 1 by bolts. The enclosure adopts a waterproof and dustproof sealed design. The internal main control module 51, speed drive module 54, LED dimming drive module 55, power supply module 56 and wireless signal transmission module 57 are integrated. All the circuits are neatly arranged and have good protection and insulation performance.

[0032] The rotary drive mechanism 4 is installed at the center of the top plate of the equipment housing 3. The core power component is a servo motor 41, which is connected to a reduction gear set 42. The reduction gear set 42 matches the torque and speed, and the output axis passes through the top plate of the housing. It is fixedly connected to the multifaceted LED cube screen 2 above by bolts through a rotary support 43. The servo motor 41 supports stepless speed regulation, operates smoothly, has high speed regulation accuracy, and can accurately respond to the speed control commands of the main control module 51.

[0033] The multi-faceted LED cube screen 2 has a regular hexagonal hollow aluminum alloy frame structure, which is lightweight and has high structural strength. All six exterior facades are equipped with high-definition LED display modules 21. Each LED module is independently electrically connected to the LED dimming driver module 55, which can synchronously complete the brightness adjustment. It supports multi-faceted synchronous or split-screen display of different advertising content, and has a rich three-dimensional display effect.

[0034] The intelligent sensing and control system 5 is the core innovative part of the equipment, and its specific workflow is as follows:

[0035] The pedestrian flow detection module 52 uses a high-definition visual recognition camera, which is fixedly installed at the top corner of the support base 1, facing the advertising display area. It collects images in real time and uses image recognition algorithms to count the pedestrian flow and density of people staying on site, completing data collection and transmission once per second. The main control module 51 presets three levels of pedestrian flow thresholds and corresponding speed levels: Level 1 (pedestrian density ≥ 15 people / ㎡), controls the servo motor 41 to rotate at high speed to increase the frequency of advertising exposure; Level 2 (5 people / ㎡ ≤ pedestrian density < 15 people / ㎡), controls the motor to rotate at medium speed to maintain the normal advertising display rhythm; Level 3 (pedestrian density < 5 people / ㎡), controls the motor to idle at low speed; in the absence of detection, the motor stops running and the cube screen remains in standby mode.

[0036] The ambient light detection module 53 uses a high-precision photosensitive sensor and is equipped with a transparent dustproof and waterproof protective cover on the outside. It can detect the ambient light intensity of 0-10000 lux in real time. The main control module 51 presets multiple brightness matching parameters: outdoor strong light (light intensity ≥ 5000 lux), the LED module is adjusted to the highest brightness to ensure long-distance visibility; indoor normal light (1000 lux ≤ light intensity < 5000 lux), it is adjusted to the standard brightness; in low light environment (light intensity < 1000 lux), the screen brightness is automatically reduced, and in extremely low light at night, it switches to the eye-protection low brightness mode to eliminate light pollution.

[0037] During equipment operation, the main control module 51 receives real-time signals from pedestrian traffic and ambient light detection, dynamically adjusting rotation speed and brightness parameters to achieve fully adaptive intelligent control without manual intervention. Simultaneously, the wireless signal transmission module 57 uploads real-time data on equipment rotation speed, brightness, energy consumption, and advertising playback. Staff can remotely view equipment status, update advertising materials, and adjust operating parameters via a terminal, making operation and maintenance convenient and efficient.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
