跨介质飞行器的分布式压电无线智能泛在感知研究
Distributed Wireless Piezoelectric Smart Ubiquitous Sensing Research for Trans-Media Aircraft
摘要
Abstract
The trans-media aircraft operate under harsh conditions while performing maritime and aerial missions,and real-time monitoring of their status is crucial to ensure safe and stable operation.This paper presents the design,development,and experimental evaluation of a low-power,high-response wireless distributed ubiquitous sensing system for external impact monitoring and evaluation of critical components of trans-media aircraft,such as landing-on-water.Due to the transient and random nature of impact events,the study combines an event-triggered mechanism with a network center requesting mechanism to exhibit low power consumption when no impact occurs and high performance when triggered.System responsiveness,robustness,and energy efficiency are considered and analyzed.Based on the system requirements and functions,the wireless sensor system is designed with modules including filtering,rectification,impact detection,local processing,and wireless communication.The system is implemented on a printed circuit board.The system is capable of accurately and timely capturing multiple piezoelectric sensing channels(8 channels).Using this ubiquitous sensing system,effective estimation of the location and energy level of external impact events can be achieved.The designed distributed piezoelectric wireless smart ubiquitous sensing system for trans-media aircraft can monitor impact events during operation,identify the location of the impacts,and promptly detect potential structural damage or safety hazards,ensuring the safe and stable operation of the aircraft.This low-latency,low-power,high-response distributed sensing system can be ex-tended to other applications on the Internet of things for monitoring rare,random,and transient events.关键词
