摘　　要：研制低压舱特殊气压条件下的人体呼吸体积流量测试设备。设计以气体质量流量传感器、气体压力传感器、温度传感器为核心的硬件,设计基于Lab VIEW平台的软件。进行了低压舱不同高度定标试验,进行低压舱不同高度验证试验。试验结果表明该设备在地面至6.9 km高度上正常运行,精度在±3%以内。低压舱专用人体呼吸体积流量测试系统能够在地面和低压舱不同模拟气压高度的低压变压环境中测量人体呼吸体积流量,能够满足低压舱高空试验的要求。To develop a set of human respiratory flow measurement equipment specifically used in altitude cabin environment. The hardware based of flow sensor,pressure sensor and temperature sensor was developed,and the software based on LabVIEW platform was designed. Test results in the altitude cabin show that the measurement system can run normally at ground to 6. 9 km altitude,and the accuracy is within the range of ± 3%. Human respiratory flow measurement system can run normally in the altitude cabin environment,and can meet the use of altitude test.
