Description

Technical Field

[0001] This invention relates to the field of lighting control technology for cold-region ice and snow landscapes, specifically to an intelligent point light source device for ice and snow landscapes with built-in sensing function. Background Technology

[0002] With the rise of cold-region tourism, ice and snow festivals, and immersive nighttime tourism projects, interactive lighting installations in ice and snow landscapes have gradually become an important element in attracting tourists. In ice sculpture exhibition areas, snow playgrounds, and winter cultural tourism towns, lighting installations not only serve the functions of illumination and decoration, but also achieve multi-sensory interactive experiences by interacting with tourists' actions and sounds, thereby enhancing the fun and technological feel of the landscape.

[0003] Existing interactive ice and snow lighting systems mostly adopt a split structure, meaning the sensors, controllers, and lighting modules are arranged separately. For example, a common approach involves an infrared or radar sensor detecting a person approaching, and the signal is fed back to the control host via cable. The host then controls the lights to change color or triggers sound playback. While such systems can achieve basic interactive functions, they suffer from numerous limitations in extreme climates such as severe cold and snow cover.

[0004] Specifically, this manifests as follows:

[0005] Sensors are prone to failure: In low-temperature environments, the detection sensitivity of sensors such as infrared and radar decreases significantly, and they may even malfunction.

[0006] Installation difficulties: The surface of ice and snow building materials is easy to melt and crack, making it impossible to provide a firm sensor mounting point, which leads to the sensor being easy to fall off or shift.

[0007] The structure is easily damaged: In traditional systems, sensors, lights and controllers are connected by multiple signal lines, which are easily squeezed or broken when subjected to ice and snow or during construction.

[0008] Rigid interactive logic: Some systems have a single configuration mode and cannot adjust the sensing sensitivity, trigger mode or response delay according to different scenarios, lacking flexibility.

[0009] For example, some research institutions have tried to deploy millimeter-wave radar on the edge of ice and snow slides and combine it with a multi-point lighting control system to achieve interaction. However, due to the separation of sensors and lights, problems such as signal interruption and feedback delay frequently occur, which seriously affects the continuity of the experience. In another example, in a certain ice and snow light show project, the sound and lights were not linked, and the sensor response range was narrow, resulting in untimely interactive response and poor experience feedback from tourists.

[0010] In summary, existing interactive systems for ice and snow landscapes are still unable to provide a highly stable and sensitive integrated interactive experience in extremely cold, slippery, and heavily covered application environments. Significant technical bottlenecks remain, particularly in terms of sensor low-temperature adaptability, structural integration, deployment flexibility, and interactive effect adjustment.

[0011] Therefore, there is an urgent need for an intelligent point light source device for ice and snow landscapes that can highly integrate sensors, lighting, control, and sound systems, and has good low-temperature adaptability and multi-parameter adjustable capabilities, in order to solve the technical problems of high failure rate, difficult maintenance, and poor interactive effect of traditional structures in practical applications. Utility Model Content

[0012] To address the shortcomings of existing ice and snow landscape interactive systems, which cannot provide a highly stable and sensitive integrated interactive experience in extremely cold, slippery, and heavily covered application environments, the technical solution provided by this utility model is as follows:

[0013] A self-sensing intelligent point light source device for ice and snow landscapes includes:

[0014] The main control module is used to receive sensor signals and output control commands;

[0015] A multi-sensor module is used to collect preset signals, and the multi-sensor module is electrically connected to the main control module;

[0016] The lighting driver module is connected to the main control module and is used to receive the PWM dimming signal output by the main control module;

[0017] A programmable light array is located on the front of the device and is driven by a light driver module to display preset lighting effects.

[0018] A configuration module, located on the back of the device, includes a digital display unit and multiple buttons. The configuration module is connected to the main control module and is used to set the sensor type, sensitivity, and light parameters.

[0019] The multi-sensor module and the programmable light array form an integrated package structure. The sensors are installed in the sensor mounting holes of the device housing and are self-heated by the heat generated when the LED light array is working.

[0020] Furthermore, a preferred embodiment is provided in which the multi-sensor module includes an infrared sensor, a millimeter-wave radar, a light sensor, and a sound sensor.

[0021] Furthermore, a preferred embodiment is provided, which also includes a sound module connected to the main control module, used to output corresponding sound effects according to the control instructions of the main control module.

[0022] Furthermore, a preferred embodiment is provided, which also includes a power supply module for supplying power to each module.

[0023] Furthermore, a preferred embodiment is provided, wherein the main control module is an STM32G0 series microcontroller with multiple GPIO interfaces and a serial communication port.

[0024] Furthermore, a preferred embodiment is provided in which the programmable light array is composed of 5050 model RGB tri-color LEDs, arranged in a matrix structure, and each color supports 256 levels of PWM grayscale adjustment.

[0025] Furthermore, a preferred embodiment is provided in which the lighting driving module includes an opto-isolation circuit and a constant current source driving circuit to improve the stability of PWM signal transmission and the accuracy of driving current.

[0026] Furthermore, a preferred embodiment is provided, wherein the configuration module includes a two-digit LED seven-segment display and four function buttons, which are used to set the sensor type, sensitivity, light mode and return time, respectively.

[0027] Furthermore, a preferred embodiment is provided in which the sensor mounting holes are achieved through a soft adhesive sealing structure, distributed on the front and back of the device, for adapting to different types of sensors and providing waterproof capability.

[0028] Furthermore, in a preferred embodiment, the main control module is also used to write the various parameters set by the configuration module into the Flash non-volatile memory, and automatically read the initialization settings each time it is powered on.

[0029] A self-sensing ice and snow landscape is also provided, including the aforementioned intelligent point light source device.

[0030] Compared with the prior art, the advantages of the technical solution provided by this utility model are as follows:

[0031] The design integrates the sensor module with the lighting device, allowing the sensor to be directly mounted inside or on the surface of the point light source. This avoids sensor displacement, damage, or failure caused by snow accumulation, extreme cold, or structural impacts. Compared to traditional split systems, this approach significantly improves stability and reliability in frigid environments and substantially reduces system maintenance frequency.

[0032] By integrating infrared sensors, millimeter-wave radar, light sensors, and sound sensors into a single multi-sensor module and employing a multi-interface design with waterproof, soft-sealed ports for flexible deployment, this approach solves the problems of limited sensor installation methods and poor adaptability in existing technologies. This method enhances the system's adaptability to different interactive scenarios, facilitates rapid deployment and reconfiguration, and outperforms most existing devices that only support a single sensing method.

[0033] By utilizing the heat generated by the LED light array itself during operation to thermally compensate for the internal sensor, the sensor can operate in a relatively stable temperature environment. This method effectively alleviates the problems of accuracy drift and slow response caused by drastic temperature changes in cold regions. Compared to the complex system in current research that uses an independent heater for temperature control, this method has a simpler structure and lower energy consumption.

[0034] Digital signal processing and PWM dimming control mechanisms are introduced into the main control module to achieve synchronized response of light and sound by accurately identifying signal characteristics from multiple sensors. The lighting driver module is connected to the constant current source driver chip through an opto-isolation circuit, making the LED point light source display more stable. This approach avoids the flickering or response delay problems that are prone to occur in traditional low-speed microcontroller-controlled lighting systems, thus improving the smoothness of the interactive experience.

[0035] The configuration module combines a digital display with four-button input, allowing users to set various parameters such as light color mode, sound response, sensor type and sensitivity, and return time. These settings are automatically stored in Flash memory. This approach enables the device to flexibly adapt to different interactive scenarios, far surpassing most commercially available interactive lighting systems with fixed functions and parameters, thus enhancing user-defined control capabilities.

[0036] By centrally powering all functional modules with an integrated power supply module, the redundancy and fault risks associated with multiple power supplies are reduced. Simultaneously, the system's internal overcurrent and overvoltage protection mechanisms ensure the safety and stability of the power supply system in complex, cold environments. Compared to existing distributed power supply solutions, this invention features a more compact structure and stronger system fault tolerance.

[0088] Installation and assembly relationships between modules

[0089] The main control module 1 is located in the core position inside the device, usually installed in the center of the main control circuit board. It serves as the control and signal aggregation unit for various functional modules and is electrically connected to the multi-sensor module 2, the lighting drive module 3, the sound module 5, the configuration module 6, and the power module 7 via ribbon cables or PCB traces.

[0090] The multi-sensor module 2 is arranged around the main control module, and its multiple sensors are connected to the main control module via ribbon cables. Infrared sensor 21, millimeter-wave radar 22, light sensor 23, and sound sensor 24 are embedded in mounting holes on the front and rear housings, respectively.

[0091] The front surface has 6 sensor mounting holes 9, which are sealed with soft glue, suitable for deploying sensors (such as infrared sensors) facing the tourist direction.

[0092] Four sensor mounting holes 9 are provided on the rear shell, which are suitable for placing auxiliary sensors (such as light sensors, sound sensors, etc.) that are not directly facing the interaction direction.

[0093] Each sensor is located around the perimeter of the lamp housing to ensure multi-directional sensing coverage.

[0094] The lighting driver module 3 is located beside or below the main control module 1 and is connected to the main control module via a ribbon cable. This module has an independent constant current output port with the programmable lighting array 4, which is usually connected by a short-distance cable or directly on the board to reduce voltage loss and signal interference.

[0095] The programmable light array 4 is an LED matrix board, directly mounted on the front of the lamp body and fixed to the inner wall of the housing by screws or slots, forming the main display surface. The rear of the LED light board is electrically connected to the light driver module, and the lighting effect is controlled by the driver module. The entire array is located at the front of the device and serves as the visual output interface of the device.

[0096] The sound module 5 is located inside the lamp body near the rear or side shell, and its waterproof speaker interface 10 is exposed through the rear shell of the lamp body for connecting to an external waterproof speaker. The sound module is connected to the main control module 1 via a serial cable, and the sound output direction is arranged opposite to the LED display direction to avoid sound source interference with visual recognition.

[0097] Configuration module 6 is fixed to the control panel area on the back of the lamp body. Its outer casing features a digital display and four function buttons for user parameter settings and mode selection. This module connects to the main control module via a GPIO interface and serves as the user interface for system interaction. Its structure is waterproof and sealed, making it suitable for outdoor operation.

[0098] The power module 7 is installed in an independent cavity at the bottom or rear of the lamp body. It shares the main power supply bus with the main control module 1 and the lighting drive module 3. The output end of the power module is also equipped with a protection circuit, and a waterproof interface is set at the connection with the external power supply to ensure stable power supply for the whole machine.

[0099] Implementation Method 3: Combination Figure 1 and 2 This embodiment describes the technical solution provided above in further detail through specific examples. Specifically:

[0100] It includes the following components: main control module 1, multi-sensor module 2, light driver module 3, programmable light array 4, sound module 5, configuration module 6, and power supply module 7.

[0101] The main control module 1 receives the sensing signals from the multi-sensor module 2, and uses digital recognition technology to determine changes in ambient light intensity, triggering actions of the user, or the strength of sound input signals. It then sends corresponding light change commands to the light driver module 3 and sound effect control signals to the sound module 5. The light driver module 3 drives the programmable light array 4 to display light changes, while the sound effect control signals control the sound module 5 to emit sound, thus achieving an interactive effect that links light and sound.

[0102] The multi-sensor module 2 can select and connect various types of sensors such as infrared sensors, millimeter-wave radar, light sensors or sound sensors according to the actual interactive application project. It amplifies and converts the voltage and current of different types of sensors into AD signals and transmits the converted signals to the main control module 1.

[0103] The lighting driver module 3 receives the instruction signals from the main control module 1 and controls the interactive lighting trigger display of the programmable lighting array 4 through the driving circuit to ensure the stability and reliability of the lighting interactive system.

[0104] The programmable light array 4 receives the drive signal from the light driver module 3 and displays specific light effects;

[0105] The sound module 5 receives instruction signals from the main control module 1 and controls the speaker to emit corresponding interactive sound effects;

[0106] Configuration module 6 receives keyboard signals input to main control module 1 to set sound effects, sensor sensitivity, light change mode before and after sensor triggering, and time to return to default state, etc.

[0107] Power module 7 provides power to all modules.

[0108] Example 1: The following is combined with Figure 1 and Figure 2 This embodiment describes a self-sensing intelligent point light source used in an interactive ice and snow landscape system, comprising a main control module 1, a multi-sensor module 2, a light driving module 3, a programmable light array 4, a sound module 5, a configuration module 6, and a power supply module 7.

[0109] Example 2: The main control module 1 uses an STM32G0 series MCU. The infrared sensor and millimeter-wave radar sensor share a single RS485 interface. After level conversion via an RS485 chip, the signals are input to the MCU's serial port 1. The signals from the light sensor and sound sensor are amplified by an AD8237 operational amplifier and then input to the GPIO. The main control module 1 scans the keyboard input signals of the configuration module 6 via the GPIO and simultaneously controls the LED seven-segment display to show interactive information. The main control module 1 controls the light driver module 3 to output interactive light control signals via the MCU's PWM dimming output. The PWM frequency is set to 1.2kHz to avoid flickering. The main control module 1 sends commands to the sound module 5 via the MCU's serial port 2 to control the sound output.

[0110] Example 3: The multi-sensor module 2 adopts a multi-signal input interface design. Nine sensor mounting holes with soft rubber waterproof sealing structures are reserved on the front, sides, and rear of the point light source device. Various sensor types, such as infrared sensors, millimeter-wave radar, light sensors, or sound sensors, can be selected according to the actual needs of the ice and snow landscape interactive application. The sensor installation position can also be flexibly selected according to the lighting installation method. In cold and low-temperature conditions, the accuracy of most sensors will decrease due to factors such as temperature gradient effects and thermal expansion and contraction, leading to sensor failure in the interactive system. The integrated structure of the sensor and lighting device can fully utilize the heat generated by the LED lighting device to heat the sensor, thus maintaining the sensor within its designed operating temperature range. Installing the sensor inside the lighting device also solves the problem of sensor installation in ice and snow building materials in traditional lighting interactive systems, avoiding the problem of sensor damage from compression and collisions caused by ice and snow materials. This greatly reduces the complexity of the lighting interactive system under harsh cold conditions, increases the system's reliability, and ensures the normal collection of user position and movement data under cold outdoor low-temperature conditions, transmitting it to the main control module 1. In practical applications, the four types of sensors can be selected and connected as needed. The infrared sensor is mainly used for human interaction sensing, the millimeter-wave radar is used to sense the number of tourists and link the lighting effects, the light sensor is used to adjust the lighting effects of the point light source according to the ambient light brightness, and the sound sensor is used for interactive projects that adjust the lighting effects according to changes in sound pressure level.

[0111] Example 4: The lighting driver module 3 consists of a PWM receiving port, an overvoltage and overcurrent isolation protection circuit, and a constant current source driver circuit. The lighting driver module 3 receives the PWM dimming signal sent by the MCU and connects to the LED constant current source driver chip via the opto-isolation protection circuit;

[0112] Example 5: Programmable light array 4 consists of 5050 surface-mount RGB tri-color LEDs arranged in a matrix. A constant current source drives the RGB tri-color LEDs to display 256 levels of grayscale for each color according to a PWM dimming signal.

[0113] Example 6: The sound module 5 consists of a serial interface connected to the MCU, a sound processing chip, a sound memory, an audio power amplifier, a waterproof speaker interface 10, and a speaker. It receives sound playback commands sent from the MCU's serial port, controls the sound processing chip to select a specified sound effect file from the Mini SD card in the sound memory for playback, and amplifies the sound signal through the audio power amplifier before outputting it from the waterproof speaker interface 10 to drive the speaker to produce sound.

[0114] Example 7: Configuration module 6 consists of two sets of LED seven-segment displays, four selection buttons, and control and power supply circuits. The LED seven-segment displays and selection buttons are connected to the main control module 1 via the MCU's GPIO port. Each press of the SET button switches between adjustment modes, sequentially used to select the sensor type, adjust sensor sensitivity, adjust the default light mode, adjust the light trigger mode, adjust the light trigger return time, and adjust the interactive volume. The up and down arrow buttons are used to increase or decrease the set value after selecting a mode. The OK button is used to confirm and save the selected set value. The MCU hardware program saves the set value after each press of the OK button to non-volatile Flash memory. The MCU reads these set values ​​each time it powers on to complete the initialization of the interactive settings.
