混合式TOF传感宠物狗呼吸监测系统的设计
Design of a respiration monitoring system for pet dogs based on hybrid TOF
摘要
Abstract
To address the clinical need for continuous respiratory rate monitoring in dogs with heart fail-ure,this study developed a novel non-contact respiratory monitoring system based on Hybrid TOF(opti-cal time-of-flight)sensing.A hybrid single-point/array TOF sensing architecture was proposed,incorpo-rating a spatial adaptive monitoring model to accommodate varying pet postures.An STM32-embedded platform enabled sensor synchronization and raw signal preprocessing,while a LabVIEW-based host com-puter implemented real-time respiratory waveform analysis algorithms.Optical calibration tests optimized array TOF ranging parameters.Testing on small-sized dogs under static conditions demonstrates a respira-tory rate measurement error of≤2 breaths per minute(BPM).The LabVIEW interface enables real-time visualization of respiratory waveforms and BPM values,confirming the feasibility of optical TOF sensing for vital sign monitoring.The hybrid TOF system achieves high-precision static respiratory moni-toring in dogs through optical measurement optimization and spatial adaptive strategies,which provides a miniaturized,low-cost bionic optical solution for veterinary medical applications.关键词
