光纤传感器信息处理系统的研究与设计

Research and design of optical fiber sensor information processing system

为了提高信息系统的性能,设计基于光纤传感器的信息处理系统。系统使用迈克尔逊光纤干涉仪采集外部信息,将所采集到的信息传导给现场可编程门阵列进行模式转换和存储等处理,通过以STM32F407处理芯片和ENC28J60通信芯片为核心的数字信号处理器实现远程信息监管和在线报警。介绍了将RT-Thread操作系统移植到STM32F407的系统嵌入式开发方法,并通过RT-Thread对显示器进行驱动,实现了对信息处理过程的管控和显示。实验结果表明,所设计的系统对信号的调节能力强,实时性和抗干扰性良好。

In order to improve the performance of information system, one based on optical fiber sensor is de- signed. This system use Michelson fiber interferometer to collect external information and process them for pattern transform and storage by FPGA. To realize remote monitoring and online alarm by the digital signal processor based on STM32F407 processing chip and ENC28J60 communication chip. It introduced the embedded development scheme of RT-Thread operation system replacing the STM32F407. And drive the screen through RT-Thread to realize manage- ment and display od information processing. The experimental results show that this designed system has the strong ad- justment, good real time performance and the anti-interference ability.
