摘要
针对目前涡街流量计存在精度不高的问题 ,采用 Toeplitz自相关矩阵近似的准牛顿算法 ,对涡街传感器输出信号进行数字信号处理。针对客户超低功耗的要求 ,开发设计以超低功耗的混合信号处理器 (MSP430 F1 4 9)为微处理器 ,以采用 KS0 71 3为控制器的 LCD为液晶显示模块 ,符合
Firstly,this article introduces the drawbacks in th e vortex shedding flowmeter According these, the writer introduces how to use the autocorrelation m atrix and the Quasi-Newton algorithm to deal with the input-signal Then,it introduces the embedded digital intelligent vortex shedding flowmeter that controlled by MSP430F149,displays the data by a LCD that control led by KS0713,uses the HART network protocol
