摘　　要：高空平流层飞艇飞行过程中的各项数据是非常珍贵的;对比分析了数据记录仪现状及平流层飞艇对数据记录的实际需求,提出了平流层飞艇数据记录仪的设计方案,详述了方案中的硬件组成、软件框架及控制流程;结合工程实际经验,设计了一系列针对该数据记录仪的测试试验,验证了设备对6.4kPa,-20℃环境的适应性,测得可靠传输速率为13kbps,总功耗小于1W,结果表明该设备满足高空平流层飞艇上对于数据记录的需求;结合高空飞艇的发展要求,从容量、速率、可靠性及数据接口多样性等方面对该方案提出了改进建议。The data from High altitude stratospheric airship during the flight is very valuable. A comparison was made between data log- ger current situation and actual needs for data recording on stratospheric airship, and the design of airship data logger was proposed. The hardware, software framework and control processes were descripted in detail. Series tests were carried out and the results turned out to be that the device meets the demand for data recording on airship and verified the device adapted to the environment of 6.4kPa, -20℃. The reliable transmission rate was measured at 13kbps; the total power consumption was less than 1 watt. At last, some recommendation was raised considering the airship development requirements.
