摘要
目的研制可供飞行员在地面不同的抗荷供氧加压制度下进行抗荷动作训练的仪器。方法抗荷供氧单元产生的气体压力信号经压力传感器转变为电信号,经调制、放大等处理后由数据采集系统转化为数字信号进入计算机,再由上位机软件做进一步的计算处理,最终将训练结果以图表等简明方式呈现给用户。结果本训练器可按照规定的压力制度产生多种信号控制其面罩压力及服装压力等,供飞行员进行不同加压环境下的抗荷动作训练,训练过程中可同时监测受试者的心电信号和蹬力信号并对结果进行记录存储。结论本训练器设计合理,功能全面,解决了在地面模拟加压环境实施抗荷动作训练的技术难题。
Objective To develop a training apparatus used in pilot＇ s anti-G straining maneuver on the ground with different anti-G suit and mask pressure conditions. Methods Gas pressure signals produced by oxygen supply and anti-G system were transferred to pressure sensors in order to be transformed into electrical signals. After these signals to be modulated, amplified and so on, they would be digitalized, acquired and sampled to the data card. The graph mode results would be presented based on calculating. Results The apparatus could be used to provide signals for controlling the pressure of mask and anti-G suit to train pilot anti-G straining ma- neuver under different pressure breathing conditions and monitor synchronously pilot ECG and leg power sig- nals, as well as improve the anti-G tolerance. All of the signals could be saved at the end of test. Conclusion The systematic design of the apparatus is reasonable and the key techniques related to pilot＇ s anti-G tolerance training on the ground are solved.
