摘要
针对市场上现有记录仪采集串行口通道数少,采集速率低,且价格昂贵等问题,提出了基于PC104单板机为架构的INS/GPS组合导航设备数据采集系统设计方案,给出了设计原理、系统组成以及实现方法。飞行试验结果表明该记录仪具有存存储容量大、高采样率,多串口通道,体积小和成本低等特点,满足了对INS/GPS组合导航设备进行性能评估的需要。
The recorder equipments in the market mostly exist the problems that they have fewer serial ports, lower collecting rate and they are relatively expensive. Aiming at the problems, the structure of the onboard data collecting recording system based on the embedded PC104 board for INS/GPS equipment is put forward. The system design is specified and the implementation is described in detail. Several UAV flight tests have shown that the designed system have the characteristics of large capacity, high collecting rate, multi- ports serial, low cost and also can satisfy the requirement of the INS/GPS Equipment evaluating experiments.
