摘　　要：根据抗荷训练器对信号的要求,设计并实现了基于DasyLab编程环境的信号采集与处理系统;该系统以DaqBoard1005数据采集卡为核心硬件,可同步采集气体压力、心电、流量、蹬力等信号,同时充分利用虚拟仪器的优势,对采集到的信号分别进行处理,并实时显示、存储;所设计的系统可同时采集处理多路不同种类的信号,已被成功应用于抗荷训练器中;实践证明,系统功能完备,运行稳定性和实时性好,为评价飞行员抗荷训练效果提供了判断和分析依据。According to the signal＇ s requirement of the apparatus for training pilots＇ s anti--G straining maneuver, a data acquisition and processing system was implemented based on DasyLah. DaqBoardl005 was used as the important hardware, which can acquire the pres- sure of gas, electrocardiogram, flux and the power of leg synchronously. The system also can process, display and store those signals in real time depending on the advantage of the virtual instrument. It has been used in the apparatus successfully and the practical tests verify that the function of the system is integrated and the performance is dependable. It can provide evidence for estimating and analysing the result of the anti--G straining maneuver training for pilots.
