The Development of Flow Controller Based on RF Card

Abstract:

An IC card controller based on the low-power microprocessor MSP430F1611 and RF card operation module YMG600 is developed to construct the flow prepayment system for the existing flowmeters. Considering the compatibility with the original system, the hardware with multiple interfaces is put forward on the analysis of output signal of the widely used flowmeters. It is focused on the realization of the flow signal processing circuits and IC card management module. In order to improve the safety of the system, the 3DES algorithm is adopted to encrypt the flow data. Furthermore, a linkage mechanism between the IC card controller and computer monitoring system is put forward to realize the real-time monitoring. Finally a serial of tests including flow sample and billing, it shows that the controller is characterized with good compatibility, high safety and practicability.
