[0002] With the continuous advancement of science and technology, the importance of camouflage technology in the military and security fields has become increasingly prominent. Traditional camouflage methods mainly rely on static colors and patterns, which cannot adapt to rapidly changing environments, resulting in poor camouflage effects. In recent years, the study of bionics has provided new ideas for the development of camouflage technology, especially the active color-changing ability of organisms such as chameleons, which has become a hot topic of research.

[0089] Example 1

[0090] This embodiment 1 provides a chameleon-like adaptive system based on thermochromic liquid crystal materials, and tests its response effect under different environmental colors.

[0091] The substrate layer is 2.5 cm × 2.5 cm ITO glass.

[0092] Preparation of the color-changing layer: After evenly mixing 35wt% of thermochromic liquid crystal materials including 4-n-pentyl-4'-cyanobiphenyl, 24.5wt% of 4-dodecyl-4'-cyanobiphenyl, 10.5wt% of 4-cyano-4'-pentyl-terphenyl and 30wt% of chiral dopant R811 and a silver nanowire network, the mixture is coated on a substrate layer, and the color change of the color-changing layer is achieved by controlling the temperature of the heater.

[0093] The electrodes at both ends of the chameleon skin device are led out through the ITO glass and the wires are welded to the two poles of the ITO glass using ultrasonic welding technology, making the device more stable when powered.

[0094] A schematic diagram of the structure of a chameleon-like adaptive system provided in this embodiment 1, the system includes: a color sensor, a temperature detection controller and a power output controller, such as Figure 2 shown.

[0095] As the first part of the control system, the color sensor mainly uses the TCS34725 color sensor. After power is turned on, the lighting LED emits light. After irradiating the object to be measured, the returned light passes through the filter to detect the RGB ratio value, and the color is identified based on the RGB ratio value.

[0096] Since the human eye's perception of color is not completely consistent with the RGB color model, other color spaces are usually used. For example, HSV (H hue, S saturation, V brightness), which is a color model for user senses. The RGB value is converted into a color model corresponding to the user's senses through a formula. The hue H is measured in angles, ranging from 0° to 360°, starting from red and calculated in a counterclockwise direction, with red being 0°, green being 120°, and blue being 240°, so that the detected RGB primary colors can be distinguished by the different hue values ​​of H.

[0097] The temperature detection controller includes a K-type thermocouple, a MAX6675 temperature data conversion module, and an STM32 controller. An extremely thin SMD temperature sensor is attached to the center of the chameleon device to ensure that the temperature changes of the chameleon device can be accurately and real-time monitored.

[0098] As a temperature sensor, K-type thermocouple has the characteristics of fast response and high accuracy, and can provide reliable temperature measurement in a wide temperature range. Its output small voltage signal will be processed by the MAX6675 temperature data conversion module, which can convert the analog signal of the thermocouple into a digital signal and transmit the data to the STM32 controller through the SPI interface.

[0099] The STM32 controller receives the temperature data from the MAX6675 module and compares it with the set target temperature. The controller's built-in PID control algorithm calculates the required heating or cooling power based on the difference between the actual temperature and the target temperature, and controls the working state of the heater and TEC cooling chip through PWM signals.

[0100] During system operation, the temperature detection controller will continuously monitor the temperature of the Chameleon device and provide real-time feedback to the STM32 controller. If the detected temperature is lower than the set target temperature, the system will start the heater for heating; if the temperature is higher than the target temperature, the TEC cooling chip will be started for cooling to ensure that the Chameleon device always remains within the optimal operating temperature range.

[0101] In addition, the design of the temperature detection controller takes into account the stability and reliability of the system, and adopts appropriate filtering algorithms to eliminate noise interference and ensure the accuracy of temperature data. In this way, the system can achieve efficient temperature control under different environmental conditions and meet camouflage requirements.

[0102] Power output controller, after receiving the temperature feedback signal from the chameleon device, the system first performs a temperature judgment to determine whether the current temperature is higher or lower than the set target temperature. If the detected temperature is lower than the target temperature and the system is running for the first time, the system will first start the relay and apply a high voltage (7.5V) to activate the chameleon skin for 1 to 2 seconds. This process is used to quickly increase the temperature of the chameleon skin so that it can quickly respond to subsequent temperature adjustment needs.

[0103] After the high voltage is activated, the system will immediately calculate the required heating or cooling power through the PID control algorithm. The PID control algorithm dynamically adjusts the power output of the heater or cooling plate by monitoring the difference between the current temperature and the target temperature in real time to achieve precise temperature control. Specifically, the PID algorithm will derive a final corrected control signal based on the calculation results of the three parts of proportion (P), integration (I) and differentiation (D).

[0104] The power output control adopts PWM (pulse width modulation) control mode, and drives the heater or cooling plate of the Chameleon through the low-power driver module DRV8833. The DRV8833 module adjusts the working state of the heater or cooling plate in real time according to the power value calculated by the PID algorithm. The advantage of the PWM control mode is that it can achieve efficient power regulation, reduce energy loss, and ensure that the temperature regulation of the Chameleon device is fast and stable under different environmental conditions. Figure 3 shown.

[0105] Through this comprehensive control strategy, the system can effectively respond to temperature changes, ensuring that the chameleon skin device always remains within the optimal operating temperature range, thereby achieving the ideal camouflage effect. In addition, the system design also takes safety and stability into consideration to ensure that no damage is caused to the device during high voltage activation and power regulation. Figure 4 shown.

[0106] Example 2: Apply the chameleon-like adaptive system to the intelligent camouflage system to verify its camouflage effect in different environments.

[0107] This embodiment applies the control system module described in Embodiment 1 to a specific physical scene and designs an independent camouflage model, such as Figure 5 As shown. The shell of this independent model is composed of an acrylic box, which is divided into two layers. The lower layer is used to place the control circuit and sensor module, and the upper layer simulates the three primary colors of the environment and sets the trolley track and traction line hole to facilitate the movement of the trolley.

[0108] The chameleon skin device is installed on a 3D printed car model. The overall structure of the model is as follows: Figure 6 As shown. The design of the car model takes into account lightness and flexibility to ensure that it can move smoothly on the track. The bottom of the car is equipped with wheels to facilitate free movement in the simulation environment.

[0109] For easy operation, the power supply has an external switch line. The user only needs to press the power switch, and the traction line will pull the car to the preset position. After the car reaches the target position, the system will start the color sensor in real time to monitor the color information of the surrounding environment and transmit the data to the STM32 microcontroller.

[0110] The microcontroller uses the PID control algorithm to calculate the required heating or cooling power based on the received ambient color data and the actual temperature of the chameleon skin device. The power output controller drives the chameleon's heater or TEC cooling sheet through PWM control mode, ensuring that the color of the chameleon skin can be quickly adjusted to match the surrounding environment.

[0111] Under different environmental conditions, the system can respond to color changes in real time and automatically adjust the color of the chameleon's skin to achieve effective camouflage. The adaptability and flexibility of the intelligent camouflage system were verified by testing under different lighting and background colors.

[0112] The design of this embodiment not only demonstrates the feasibility of the chameleon-like adaptive system in practical applications, but also provides new ideas and technical support for future military camouflage, security stealth and other related fields. Through continuous optimization and improvement, the system is expected to achieve more efficient camouflage effects in more complex environments.

[0113] The above is only an embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
