The Research And Development Of Intelligent Flowmeter Based C8051F060

Flowmeter is one of the important instruments which is widely used in waterconservancy industry. At present, the open channel flowmeter are mainly rotorKinemometer at home and abroad. Using this methord, the record and calculation are basedon the local manual work and can not satisfy the requirement for the faster and accuratemeasurement. The portable intelligent flowmeter introduced in this paper has characteristicsas follows: Incorporate measure of liquid level, velocity of flow and flow. Big LCD(LiquidCrystal Display) of Chinese. Accurate real-time clock. Non-volatile memory of data. Thecommunication with the master PC by RS-232. Read and write of flash disk as USB host.According to the request of this subject, the system hardware and software for the slavedevice. Detailed works are as follows:1.Using the high performance, high integration SOC(system on a chip) C8051F060successfully that is made by SYGNAL as master chip is used to capture and measurethe width of impulses, so singals of flow velocity are collected and disposed.2.the 4×4 matrix keyboard and LCD are used in the part of man-machine interface whichare easy to input, legible to read, various to display, comfy to be accepted and plain toshow measure and inquiry results.3.FRAM memory FM3164 is used to carry out the non-volatile memory of data andaccurate real-time clock.4.SL811HST chip is used as USB host which can read and write flash disk,thereby a kindof adscititious mass storage is accomplished.5.water level is surveyed via RS485 interface and pressure sensor.
