摘要
介绍了一种以C8051F060单片机为核心的智能明渠流量计。系统流量测量采用流速-水位计算法;通过旋桨式流速传感器来测量流速;通过压力传感器与RS-485接口通讯测量水位;采用铁电存储器FM3164实现了数据的非易失性存储和精确的实时时钟;采用SL811HST芯片,实现了USB主机的功能,可读写U盘,从而实现了单片机的外挂式海量存储。系统具有智能化、操作方便、硬件电路简单等特点,符合预期设计结果,具有较强的实用价值。
An intelligence open channel flowmeter based on C8051F060 is produced.Flow-liquid level method is used in order to measure the flow in the system;velocity of flow is measured through rotor flow velocity sensor;water level is surveyed via RS485 interface and pressure sensor;FRAM memory FM3164 is used to carry out the non-volatile memory of data and accurate real-time clock;SL811HST chip is used as USB host which can read and write flash disk,thereby a kind of adscititious mass storage is accomplished.This system has many characteristics,such as intellectualization,easy operation,simple hardware circuit and so on.The design result is in line with expectation.The system has a strong practical value.
