A smart lighting and sound effect scene system for park landscapes based on human body sensing

Abstract

This utility model relates to a smart lighting and sound system for park landscapes based on human body sensing. It can intelligently control the park landscape lighting based on whether anyone is present at night, with the lighting and extinguishing process performed individually for each light fixture. During the day, when people are in the park, it can play birdsong or soft music, playing different music depending on the weather. It can also adjust the lighting brightness and color according to seasonal temperature changes, enhancing the overall experience of the park landscape.

Description

Technical Field

[0001] This utility model relates to the field of intelligent control technology for park landscapes, and in particular to a system that combines human body sensing, weather conditions, and temperature changes to intelligently control park landscape lighting and sound effects. Background Technology

[0002] (a) Deficiencies in existing technology

[0003] Existing park landscape lighting mostly uses timed control or simple light-sensitive sensors, which cannot accurately achieve dynamic control based on people and environmental conditions. It can only achieve basic daytime off and nighttime on / off functionality, and the on / off state is indiscriminate, lacking flexibility and intelligence. Some park landscape systems with background music play monotonous music that does not adjust with weather and season, failing to create an atmosphere that matches the actual scene. Regarding brightness adjustment and light color, many park landscape lighting products lack the ability to intelligently respond to temperature changes, making it difficult to meet the lighting needs of different seasons.

[0004] (II) Industry Pain Points

[0005] The inability to accurately detect human activity leads to energy waste or a poor lighting experience. The lack of sound and lighting control integrated with natural environmental factors diminishes the overall immersiveness and aesthetic appeal of the park landscape. Summary of the Invention

[0006] I. Intelligent control integrating multiple factors: It integrates human body sensing, weather monitoring (sunny and rainy weather judgment), and temperature monitoring (spring, summer, autumn and winter judgment) to comprehensively control the brightness and color of park landscape lighting and play corresponding sound effects based on multiple factors.

[0007] 2. Dynamic lighting effects: Enables individual lighting to turn on and off. When lit, the lights can be triggered one by one according to a preset path or a regular algorithm. When turned off, the lights turn off one by one in reverse order, creating a unique visual effect.

[0008] 3. Precise sound effects and brightness adjustment: During the day, different sound effects such as birdsong or light music are played according to different weather conditions; throughout the year, the lighting brightness and color are adjusted in real time according to temperature changes, such as warmer tones and slightly higher brightness in winter, and cooler tones and moderate brightness in summer.

[0009] (I) System Composition: 1. Multi-mode human body sensing sensor combination: accurately captures human activity signals.

[0010] 2. Weather monitoring sensors: including raindrop sensors and light intensity sensors, used to determine sunny or rainy days and day / night times.

[0011] 3. Temperature sensor: Monitors ambient temperature in real time.

[0012] 4. Microcontroller: Receives data from the sensor module, analyzes and processes it according to a preset algorithm, and outputs control signals.

[0013] 5. Lighting Module: Composed of multiple LED lamps, each with a unique address code, allowing for individual lighting and shut-off control via a microcontroller. The brightness and color temperature of the lamps can be adjusted using PWM (Pulse Width Modulation) or the DMX512 protocol.

[0014] 6. Sound Effects Module: Includes an audio playback chip, speaker, and storage unit. It stores various music files of different styles and plays corresponding sound effects according to the instructions of the microcontroller.

[0015] (ii) Control Logic:

[0016] 1. Lighting logic:

[0017] (1) Darkness detection: Based on the data from the light intensity sensor, when the light intensity is lower than the set threshold and the multi-mode human body sensor detects someone, the lighting control mode is activated. Illumination: The lights are illuminated one by one according to a preset order (e.g., from the entrance to the central area, or according to the grid layout). The interval between adjacent lights can be set according to the actual situation, such as 0.2-0.5 seconds.

[0018] (2) Normal lighting: After all the lamps are turned on, adjust the brightness and color temperature of the lamps according to the data from the temperature sensor;

[0019] (3) Turn off one by one: When the human body induction sensors in multiple areas of the park do not detect human activity within a certain period of time, turn off the lights one by one in the reverse order of turning them on, and set an appropriate interval time.

[0020] 2. Sound Effects Logic:

[0021] (1) During the day when there are people and it is sunny: play bird chirping sound effects. The volume can be set according to the actual scene (e.g., 40-60% volume).

[0022] (2) During the day when there are people and it is raining: play soft background music, such as "Annie's Wonderland" by Bandari, and keep the volume at around 30-50%;

[0023] (3) Play cricket sound effects at night when there are people around (volume maintained at 30%).

[0024] (4) No one is present: The sound effects are off or muted.

[0025] (III) Comparison of technical effects:

[0026] index This utility model Existing technology Increase Energy saving Achieve precise control and save more than 30% on energy. Traditional control methods have poor energy-saving effects. More than 30% Sound effect scene adaptability Multiple factors match different sound effects, resulting in high compatibility. Single weather or unrelated sound effects high Lighting experience Dynamic on / off effects, adjusting brightness and color based on temperature. No dynamic effects, lack of temperature correlation high Interaction accuracy Precise interaction based on multi-sensor fusion Single sensor or fixed logic, low accuracy high Attached Figure Description

[0034] Example: Deployment of courtyard landscape lighting

[0035] 1. Hardware Configuration

[0036] (1) Deploy 2 sets of 3-mode human body sensors (installed at the entrance and exit of the park) and 3 sets of single-mode human body sensors (installed in the middle area of ​​the park).

[0037] (2) Use 32 LED tricolor in-ground lights (IP68 protection).

[0038] (3) A 32-channel timing controller (with mobile phone Bluetooth control) is used.

[0040] (5) Use light sensor, water droplet sensor, temperature sensor and time continuation device.

[0041] 2. Implementation of dynamic special effects:

[0042] (1) Entry mode: The lights are triggered at Fibonacci intervals along the direction of human movement (e.g., 1m→1.6m→2.6m).

[0043] (2). Stay mode: The activated area forms a halo gradient (center brightness 100% → edge brightness 50%), and people in the scene continue to keep the light. Exit mode: Reverse trigger + sudden drop in brightness (100% → 10% completed within 0.8s).

[0044] (3) Based on the temperature differences of spring, summer, autumn and winter, the lights automatically select different color temperatures and brightness levels to turn on.

[0045] 3. Soundscape linkage: Three audio modules installed in different areas process different sounds respectively.

[0046] (1) Audio module 1: Select different music segments according to the temperature differences of spring, summer, autumn and winter (volume maintained at 30%).

[0047] (2) Audio module 2: During the day, play birdsong (volume is inversely proportional to the distance from the human body) and switch to cricket sound effect at night (volume is maintained at 30%).

[0048] (3) Audio module 3: Select different music segments according to the weather (volume maintained at 30%).

[0049] 4. Silent processing mechanism: When continuous inactivity for more than 3 minutes is detected, the system is shut down and waits for the next cycle.
