摘要
结合时差法超声波流量测量原理,研究了一种基于超低功耗16位单片机MSP430F147的时差法超声波流量测量系统。首先介绍了时差法超声波流量测量的基本原理,然后着重讨论了超声波流量测量系统的硬件组成,最后简要介绍了该系统的软件设计。实践表明,该流量测量系统具有功耗低、功能较齐全、可靠性强等特点。
In combination with the principle of ultrasonic flow measurement applied with time-difference method, an ultra- sonic flow measurement system applied with time-difference based on 16-bit MSP430F147 SCM of ultra-low power consumption is studied. The fundamental principle of this measurement is introduced, and then the hardware structure of the measurement system is discussed emphatically, finally the software design of this system is introduced in brief. The practical results show that the flow measurement system has the advantages of low power consumption, complete functions and strong reliability.
