Active Camouflage Device And Regulation Research Based On Luminescent Thermoregulation Devices

With the advancement of military detection technology and the increasing complexity of the battlefield environment,the military’s need for camouflage technology is increasing.Traditional camouflage technology cannot cope with the ever-changing battlefield environment and is difficult to adapt to its own camouflage characteristics in response to changing scenes.Therefore,in order to solve the defects of traditional camouflage technology,active camouflage methods have begun to enter people’s research field.Active camouflage is a technology that can perceive the surrounding environment and change its own camouflage characteristics to achieve concealment and camouflage.However,the research on active camouflage devices is still limited in application,and most of them are applicable to single-band camouflage methods,while further research is needed for multi-band camouflage methods.Therefore,this article focuses on the research of visible and infrared dualband composite camouflage,and designs an active camouflage device based on the design of light-emitting temperature control devices,with the main contents as follows:Firstly,based on the light-emitting temperature control device,an active camouflage device is designed,which includes three subsystems: the light-emitting temperature control device,the dimming and color adjustment system,and the temperature control system.Firstly,by comparing and analyzing different device models,light-emitting methods,and temperature control methods,the light-emitting temperature control device is designed as a hexagonal sideemitting device model controlled by semiconductor cooling chips.Secondly,for the dimming and color adjustment subsystem,the design of the dimming and color adjustment system is carried out based on the working principle of LED light-emitting devices,including the selection of brightness compensation and color matching methods,and the selection of microcontrollers,sensors,and power supply modules for the dimming and color adjustment system,thereby completing the hardware design of the system.Finally,for the temperature control system,the working principle of the semiconductor cooling chip is analyzed,and the fuzzy PID control algorithm is selected to adjust the voltage direction and duty cycle of the input semiconductor cooling chip in real time to achieve the temperature control effect.A control system including microcontrollers,temperature sensors and DC drive modules is designed.Secondly,the main color extraction algorithm and temperature control algorithm of the active camouflage device are designed.Using computer technology,a primary color extraction algorithm for the background area of the camouflage target is designed.By selecting an area of interest in the background environment picture taken by the camera,the scope of the primary color extraction is narrowed,and the primary color extraction of the area of interest with the set color quantity of N is performed using the K-means clustering algorithm.The results show that the extracted primary colors are basically consistent with the environment colors,and the recognition of the picture to the device color display is completed within one second.In addition,the fuzzy PID control algorithm is used to control the temperature of the light-emitting temperature control device.Compared with traditional PID control,the fuzzy PID control algorithm can change the PID control parameters in real time,thereby improving the antiinterference ability of the temperature control system.The fuzzy PID temperature control model is constructed by determining the input and output variables,determining the membership functions,and determining the fuzzy control rules.Finally,the active camouflage device is constructed and its infrared and visible light camouflage effects are verified.This article realizes the operation of the active camouflage device based on the design of the light-emitting temperature control device through hardware construction and software program writing.The results show that the camouflage device has a high degree of color and brightness matching with the background environment,good adaptability,and good matching ability for complex background environments.The infrared camera shooting shows that the temperature control of the camouflage device is uniform,and the target temperature can be accurately controlled.The control accuracy of the temperature control system is within ±0.2℃.In conclusion,the dual-band composite active camouflage device proposed in this study provides a feasible solution to the limitations of traditional camouflage technology and is of great significance for the active camouflage of military targets in dynamic environments.
