Design and Implementation of an Ultrasonic Recording Shielding System Based on STM32
摘要
Abstract
As the importance of information security becomes increasingly prominent,the need for confidentiality in confidential places becomes more urgent.This design aims to develop an ultrasonic intelligent recording shielding system based on STM32 to effectively prevent sensitive information from being illegally recorded.The system transmits ultrasonic waves of a specific frequency to interfere with the work of the recording equipment,thereby protecting the content of the conversation.The system not only has real-time monito-ring and intelligent recognition functions,but also can adjust the working voltage of the ultrasonic transducer according to environmental changes,realizing adjustable output power,and ensuring the best shielding effect.关键词
