摘　　要：基于嵌入式ARM和Linux系统设计了光纤温度传感检测电路。利用Linux内核进行嵌入式的驱动程序设计;通过捕捉多个外部中断实现反射谱峰值的间接定位;利用Multisim软件对光纤传感检测电路的外围硬件进行了性能仿真;基于QT设计了嵌入式系统的图形化界面。硬件电路运行结果表明,嵌入式系统的Linux内核可以正常引导和启动,QT图形化界面可以实时显示光纤反射谱峰值以及对应的温度值。和传统的工控开发板相比,该系统对测量结果的显示更加形象直观。Based on embedded ARM and linux system, an optical fiber temperature sensor detection circuit is designed. Embedded driver programme is design by using linux kernel, indirect location of peak reflectance spectra is achieved by capturing multiple external interrupts, multisim software is used to simulate the performance of the peripheral hardware of detection circuit, and the graphical interface of embedded system is designed based on QT. The results of hardware circuit operation show that the linux kernel of embedded system can boot and start normally, and the peak value of optical fiber reflectance spectrum and corresponding temperature can be displayed in real time on the graphical interface of QT. Compared with the traditional industrial control development board, the system can display the measurement results more visually and intuitively.
