研究了基于小型无人机飞行试验的数据采集器。利用单片机C8051F121全双工串口UART实时接收飞行试验数据,将数据保存在FLASH芯片K9K8G08U0A中;采用铁电存储器FM25CL64保存数据链表;设计数据提取软件,使用者可根据需要将存储在FLASH芯片K9K8G08U0A中的数据下载到上位机中进行分析和处理。该数据采集器体积约50mm×35mm,成本仅200元,容量为8Gbit,能存储30h的试验数据,保存数据约10年,使用方便可靠,完美实现了试验数据实时记录和按需提取,具有重要的工程应用价值。
The data acquisition system based on flight test of small UAV is studied. The use of single-chip full-duplex serial port UART C8051F121 flight test data received in real time, the data stored in the FLASH chip K9K8G08U0A; ferroelectric memory FM25CL64 save the data linked list; design data extraction software, the user can be stored in the FLASH chip K9K8G08U0A Data downloaded to the host computer for analysis and processing. The data acquisition volume of about 50mm × 35mm, the cost of only 200 yuan, a capacity of 8Gbit, can store 30h test data, save the data for about 10 years, easy to use and reliable, the perfect real-time recording of test data and on-demand extraction, is important Engineering application value.
