微小型大气数据采集系统设计与实现

大气数据采集对飞行器自动控制具有重要的意义。根据系统实时性和小型化的要求,设计了一种微小型大气数据采集系统。该系统以TMS320F2812为控制器,采用高精度A/D转换器和均值滑动滤波的方法来提高测量精度;由于软件采用了μC/OS-II,大大简化了系统的管理、维护工作。该系统结构简单、体积小、成本低,试验结果表明该系统测量精度高,具有较高的实际应用价值。

Mini Air Data Collecting System Design and Implementation

Collecting and processing air data is one of the most important technology of Aerocraft＇s autopilot design.In order to meet the requirement of real timing and minitype,an mini air data collecting system was designed.The collecting system uses TMS320F2812 as main processor and a 12-bit A/D converter was used to improve data acquisition precision except for a filter method of getting mean value.The manage and maintain work was reduced for the using of μC/OS-II.This collecting system has simple structure,small size,high precision and cost performance,which has great significance to the improvement applied value proved by flight test.
