摘　　要：介绍了一种基于数字信号处理器TMS320LF2407的图像识别流量计的实现方法。通过人眼观察进行识读的传统转子流量计,直观但精度不高、灵活性不强。通过引入电荷耦合器件图像传感器采集转子流量计中转子图像,并进一步通过采用DSP处理器并应用嵌入式设计方法对转子位置进行分析,从而显著地提高了测量精度和应用的灵活性,克服了传统仪表的不足。同时可输出5-20mA电流信号,可直接应用在DCS控制系统中。An implementation of image recognition flowmeter based on digital signal processor （DSP） TMS320LF2407 is intro-duced.Classic rotor flowmeter is simple but low precision and not flexible. In this paper, Charge Coupled Device is introduced to collect the image of rotor; DSP and embedded system are applied to analysis the image information to confirm the rotor＇s position.These methods can improve the measurement＇s precision, advance the flexible of classic rotor flowmeter and overcome the disability of classic instruments. This flowmeter can be used in DCS systems because its output is electric current signal with 5-20mA.
