摘要
目的研发飞行员低压舱高空生理训练中缺氧体验训练项目使用的"飞行员缺氧体验认知负荷测试计算机模拟系统",以代替传统的纸笔倒减数字方法,提高训练效果。方法对飞行员与缺氧相关的认知能力进行分解分析,单项能力包括短时记忆力、计算能力、手眼协调能力。硬件采用了华为平板电脑为核心平台,软件使用Labview开发系统软件。系统界面包括姓名输入与功能选择区、随机数显示区、答题输入区。随机数显示区随机显示3个数字,停留一定时间后消失。操作人员即可进行3个数的求和计算后取其和的尾数,并点击答题区的相应数字。之后系统自动重新开始新的周期。系统自动记录答题时间间隔,并对操作人员的短期记忆能力进行评估。在参加高空生理训练的52名飞行员中进行了应用验证,对缺氧和正常状态下参训者的答题数和答题错误率进行统计比较。结果所有参训人员均通过了测试。测试结果表明该系统增加了缺氧训练的认知负荷,在缺氧和正常条件下的错误率差异有统计学意义(U=310.5,P<0.01)。缺氧条件下,答题错误率随缺氧时间的增加而增加。结论 "飞行员缺氧体验认知负荷测试计算机模拟系统"能够增加人员在缺氧条件下短期记忆力、计算能力、手眼协调能力等相关的认知负荷,是代替传统的纸笔倒减数字方法的可行方案。
Objective To develop a Computer Simulation System on Cognitive Load Test of the Pilots in Hypoxia used in the pilots experiencing hypoxia in low pressure cabin altitude physiological training,so as to replace the traditional paper test method and improve the training effect.Methods The cognitive abilities related to hypoxia in pilots were analyzed,including short-term memory,calculation ability and hand-eye coordination ability.The hardware adopted Huawei tablet computer as the core platform,and Labview was used for software development.The system interface included name input and function selection area,random number display area and answer input area.Three numbers were randomly displayed in display areas,and disappeared after staying for a certain time.The operator could sum the three numbers and choose the mantissa of result,and click the corresponding number in the answer area.After that,the system automatically started a new cycle.The system automatically recorded the time interval of answering questions and evaluated the short-term memory ability of operators.The test was carried out in 52 pilots who participated in altitude physiological training,and the statistical comparison was made on the number of answers and error rate between the participants under hypoxia and normal conditions.Results All participants passed the test.The test results showed that the system increased the cognitive load of hypoxia training,and the error rate was significantly different between the pilots under hypoxia and normal conditions(U=310.5,P<0.01).Under the condition of hypoxia,the error rate of answering questions increased with the time.Conclusions The cognitive load simulation system of pilots,hypoxia experience training can increase such related cognitive loads on as short-term memory,calculation ability,hand eye coordination ability,which is a feasible alternative to replace the traditional paper test method.
