涡街流量计信号处理系统采用MSP430的单片机硬件设计

Signal Processing System of Vortex Flowmeter Uses Hardware Design of MSP430 Single-Chip Microcomputer

涡街流量计易受噪声干扰,现场测量精度不易保证。对涡街流量计的原理以及以MSP430型单片机为核心的智能涡街流量计硬件电路做了介绍,讨论了系统各部分的功能。设计所采用的单片机和元件都具有低功耗的特点。

Since vortex flowmeters are easy to be disturbed by noises their field measurement accuracy cannot be guaranteed. The principles of vortex flowmeter as well as intelligent vortex flowmeter hardware circuit whose core is MSP430 single-chip microcomputer are introduced, and the functions of various parts in the system are discussed. The chip calculators and components used in the design are of low power consumption.
