摘要
提出并设计基于FPGA的超声波流量计。以单片机为核心的超声波收发电路,以及使用verilog设计的FPGA控制单元。外围电路设计简单可靠,利用FPGA在提高最高时钟频率方面的优势,大大提高了设计的测量精度。
This paper designs an fpga-based ultrasonic flowmeter, the ultrasonic transceiver circuit microcontroller as the core, and to use verilog language design fpga control unit, Peripheral circuit is designed to be simple and reliable, the fpga advantage in raising the maximum clock frequency, greatly improve the measurement accuracy of the design.
