摘要
传统的导弹遥测数据采集系统使用的是工控机箱加PCI板卡的模式,整套系统较为繁杂,不便于外场测试,本次设计的USB数据采集系统可应用于带有USB接口的便携式笔记本电脑,系统设计简单,可靠,实现了数据采集、开关控制、数据可视化和存储等功能,且通过添加、更改部分固件系统代码,实现了特殊的指令功能;经实际测试,传输速度可达到30Mbyte/s,完全满足测试系统的需求,且为后期系统升级预留了很大的空间。
Traditional Data Acquisition System uses Industrial PC with a PCI card in it, the hardware system could be complicated. This paper designed a USB portable data acquisition system which can be used in any computer with a USB port. The system is simple and reliable and implements data visualization, storage and some other basic functions. This design also implements some special functions by adding codes into the firmware. After practical test, the highest speed of the system can reach 30Mbyte/s, which not only satisfies the sys- tem requirements but also reserves space for upgrade.
