摘　　要：嵌入式ARM解调是解决传感器小型化一种有效的途径。基于LabVIEW图形化编程、围绕具有Cortex—M4内核架构的STM32F407ZGT6处理器进行嵌入式开发,开发的ARM的解调终端对激光光纤气体传感器输出的电压信号进行实时采集、处理,获得最终的气体体积分数,并进行实时显示和数据传输。测试结果表明:基于LabVIEW开发的嵌入式ARM解调终端和上位机通信软件均完全满足应用要求。Embedded ARM demodulation is an effective way to solve sensor miniaturization. LabVIEW graphical programming and STM32 F407 ZGT6 with Cortex-M4 core architecture are used for embedded development.Voltage signal output by laser optical fiber gas sensor is collected and processed by the ARM demodulation terminal in real-time and volume fraction of gas is obtained, displayed and transmitted in real-time.Test result shows that the embedded ARM demodulation terminal and the host computer communication software based on LabVIEW meet application requirements.
