摘要
提出了一种基于射频卡的低功耗热量表的软、硬件设计方法。采用了Atmel公司的T5557射频卡实现预付费功能,应用目前国际上功耗最低的MSP430FW425单片机为主控制器,Pt1000为温度传感器,其流量测量部分采用无磁流量计和韦根流量传感器,提高了测量的精度和灵敏度。
The design of an RF card heat meter with its software and hardware is proposed. The T5557 RF card produced by the Atmel Company is used to achieve prepayment function. The MSP430F425 is used as control MCU, Pt1000 for temperature measurement and the new measurement for volume flow is recommended, which improve the precision and sensitivity of flow measurement.
