超低功耗智能涡街流量计的硬件设计

Hardware design of ultra-low power consumption intelligent vortex flow meter

智能涡街流量计系统由涡街传感器、温度传感器、压力传感器、液晶显示模块、主控制器等几个部分组成。主控制器使用单片机对各个传感器的信号进行采集、分析、计算,并进行补偿,得到所需数据,再将各种数据送到液晶显示器显示。本文重点论述了主控制器的硬件实现。在设计中,采用了耗电少的MSP430F149单片机,各部分采用微功耗设计,并引入日历时钟,将日历时钟和流体的流量结合在一起,便于流量数据的查询。

The intelligent vortex flow meter is consisted of vortex sensor,temperature sensor,pressure sensor,LCD module and master controller,etc.A single-chip micro computer is used as the master controller to collect,analyze,compute and compensate the signals of all sensors,and gets the needed data,then displays all data via the LCD.The paper mainly describes the realization of hardware of the master controller.In the hardware designing,the system takes use of the lower power-consuming MSP430F149 single-chip micro computer,combined with micro-work consuming design of other parts.A real time clock application,which is combined with the flow of liquid,makes inquiry the flow data conveniently.
