摘要
根据测试现场的实际需要,设计了以AT91 SAM9G45处理器为核心,基于Linux操作系统的无线数据传输系统。介绍了数据无线传输的过程,设计了FT245驱动程序和应用程序。测试系统将采集到的数据传输给ARM,经过压缩存储等处理后利用WiFi发送给上位机,在上位机上对数据进行后续处理和显示。利用硬件电路和软件系统实现了数据的压缩存储、无线传输、数据的处理和显示等功能。为了使系统具有通用性、调试方便,还设计了串行接口、USB接口等。
According to the actual requirements of test site,a wireless data transmission system is designed based on AT91SAM9G45 processor and Linux operating system.The wireless data transmission process is introduced.The driver program and application program of FT245 are designed.The collected data of test system are transferred to the ARM.After a compressed storage,the ARM controls WiFi send data to the host computer.The host computer deals with the subsequent process and displays the data.By designing hardware circuit and software system,data compression and storage,wireless data transmission,data processing,and data display are realized.To make the system have the versatility and facilitate debugging,serial interface and USB interface module are designed.
