基于TMS320F28335的超聲波流量計硬件原理圖+軟件源碼本文以TMS320F28335 處理器為核心，設(shè)計一種用于管道流量測量的超聲波流量計。系統(tǒng)硬件由核心板，超聲波發(fā)射和接收電路，切換電路，超聲換能器，基于ADS805 的高速信號采集電路，人機(jī)交互以及電源等模塊構(gòu)成。采用時差法進(jìn)行管道流量測量，時差測量采用SCOT 加權(quán)的廣義互相關(guān)時延估計算法。本論文設(shè)計的超聲波流量計具有測量速度快、準(zhǔn)確性好、成本低等優(yōu)點(diǎn)。關(guān)鍵字：C2000，超聲波，流量，廣義互相關(guān)算法AbstractA kind of ultrasonic flowmeter using for the pipe flow measurement is designed based onTMS320F28335 in this paper. The system hardware consists of the following parts: the core board,ultrasonic signal transmitter and receiver circuits, switch circuit, ultrasonic Transducer, signalacquisition circuit based on ADS805, human-computer interaction module and power supplymodule, etc. The system use the method of time difference for pipeline flow measurement and thetime difference is calculated by the time-delay algorithm of SCOT weighted generalizedcross-correlation. The ultrasonic flowmeter has the features of high testing speed, high precisionand low cost, etc.Keywords: C2000,Ultrasonic, Flow, Generalized Cross-Correlation Algorithm
