摘要
近年来,儿童存在探测功能装车率逐渐提升,雷达、UWB探测等是实现该功能的主要技术手段,可直接探测儿童的呼吸来判断儿童存在.但目前该测试用假人的呼吸参数定义不完善,现有的假人呼吸参数不统一,因此对测试工具呼吸参数进行定义非常重要.文章对呼吸频率和呼吸幅度两个参数进行分析,并通过多组比对试验证明了呼吸幅度的重要性.对0岁、1岁、3岁、6岁真人儿童的呼吸参数进行实际测量,通过数据统计分析,得到各年龄段CPD假人的呼吸频率和呼吸幅度的定义值.研究结果为完善和提升CPD假人的生物仿真性能提供了依据,使CPD系统的测试结果更加可靠、有效.
In recent years,the installation rate of child presence detection(CPD)function has gradually increased.Radar,UWB detection,and other technologies are the main means to achieve this function,which can directly detect children′s breathing to determine their presence.However,the definition of respiratory parameters for the test dummy is currently incomplete,and the respiratory parameters of dummies from different suppliers are not uniform.Therefore,it is very important to define the respiratory parameters of the testing tool.The article analyzes two parameters,respiratory rate and respiratory amplitude,and proves the importance of respiratory amplitude through multiple comparative tests.Actual measurements were taken on the respiratory rates and amplitudes of 0-year-old,1-year-old,3-year-old,and 6-year-old real children,and through data statistical analysis,the defined values of respiratory frequency and amplitude for CPD dummies in each age group were obtained.The research results provide a basis for improving and enhancing the biological simulation performance of CPD dummies,making the testing results of CPD systerm more reliable,and effective.
