摘要

针对在平原地区模拟高原低氧环境训练的需求,提出了一种低氧呼吸训练装置控制系统.基于LabVIEW平台,对训练环境的气压、温度和含氧量等参数进行采集和运算,实现了对训练数据的实时记录和显示;采用位置式PID算法对系统参数的变化进行整合,进一步提高了控制精度.结果表明,该装置能够模拟高原不同海拔低氧环境,实现参数自动调节与控制,具有较好的应用价值.%Aiming at the demands for simulating the high altitude hypoxia environment training in the plain area, the design scheme of control system for the hypoxic breathing training device is put forward. Based on LabVIEW platform,the atmospheric pressure,temperature and oxygen content and other parameters of the training environment are collected and operated,to achieve real-time recording and displaying of the training data;the variation of system parameters is integrated by using positional PID algorithm,and the control precision is improved in further. The results show that the device can simulate hypoxia environment of plateau at different altitudes,and realize automatic regulation and control of system parameters,it has good applicable values.
