摘要
针对航空电子设备车载试验缺乏独立高度测量数据,无法充分模拟机载环境的缺陷,本文利用芬兰VTI公司SCP1000-D01传感器芯片完成了基于USB接口的气压高度计设计。通过该气压高度计进行低空数据采集分析,文中得出气压高度计在较短测量时间内具有良好的稳定性,高度差值更精确的特点。这与高空飞行数据的气压高度测量数据分析结论相一致,表明该便携式气压高度计能够弥补现有车载试验缺乏独立高度测量的缺陷,并具备低成本、方便灵活的优点。
The paper presents design of a kind of USB - based baro - altimeter which employs SCP1000 - 1901 sensor chi Pof VTI Corp. , Finland. The baro - altimeter is used to solve a realistic problem that vehicle - borne experiment of aviation electronic instru- ments is lack of independent altitude measurement data and airborne environment cannot be simulated completely. Based on data col- lection in low- altitude air, a conclusion is drawn that this baro- altimeter has good stability in short- time measurement, with more accurate altitude difference. This is consistent with the conclusion drawn from analysis of flight baro - altimeter measurement data in high - altitude air. It indicates that this baro - alimeter is able to provide independent altitude measurement data in vehicle - borne experiment, with low cost and enough flexibility.
