摘　　要：以ARM微处理器和现场可编程门阵列(FPGA)芯片为核心,设计了基于Linux系统下的红外电力监控系统。以FPGA的存储电路和与ARM处理器的接口电路,为红外图像搭建数据通道。以ARM-Linux操作系统下的QT来开发电力监控的软件系统,实现红外图像的采集、处理以及温度监控等功能。该系统充分利用了ARM微处理器的控制能力和FPGA的高速并行运算能力,大大减少了系统的外围接口器件,有效地降低了系统的成本。Recently, embedded systems is widely used in the monitoring system. An IR Power Monitoring System based on Linux system is designed in this paper and the core of the system is ARM microprocessor and field programmable gate array （FPGA） chip. Using the memory circuit of FPGA and the interface circuit of ARM microprocessor, data channel for the infrared image is built. This system develops the software system in power monitoring by the QT, which is under the ARM-Linux operating system, and completes the collecting, processing and temperature monitoring of infrared image. The system makes full use of the ARM microprocessor control and high-speed parallel computing power of FPGA, reducing the system＇s peripheral interface devices considerably and reducing the cost of the system effectively.
