摘要
超声波流量计是目前应用较广泛的一种流量计量设备,它以非接触方式进行流量计量,具有良好的应用前景。设计了一种基于ARM和FPGA的超声波流量计系统,以MSP430FG4618和XC2C32A为控制核心,超声波换能器接收信号经过处理后利用低功耗电压比较器MAX9202转换成数字信号,再传输给XC2C32A。为了防止因流体温度过高对传感器的性能造成影响,样机中设计了温度测量电路进行进回水温度的测量,对系统进一步优化。
Ultrasonic Flowmeter is a kind of flow metering equipment which is widely used at present.It is in the manner of non-contacting way to measure flow,and it has a good application prospect.This paper designs an ultrasonic flowmeter system based on ARM and FPGA,which takes MSP430 FG4618 and XC2 C32 A as the control core.After processing,the ultrasonic transducer receives the signal and converts it into digital signal by using the low power voltage comparator MAX9202 and then transmits it to the XC2 C32 A.In order to prevent the influence of excessive fluid temperature on the performance of the sensor,a temperature measuring circuit is designed in the prototype to measure the inlet and return water temperature,and the system is further optimized.
