摘要
为了实现某净水机设备的智能管理,采用增强型单片机芯片STC89C58RD+作为MCU,由实时时钟芯片DS1302和涡轮流量传感器获得的时间和流量信号构成闭环控制系统,运用DES加密算法形成智能IC卡安全应用体系,以Visual C++6.0为开发平台设计上位机管理软件界面;应用结果表明,该净水机智能管理系统具有稳定可靠、安全性高和易于管理等优点,系统时间误差控制在每天1s以内,流量标准误差为0.89%,系统综合误差小于1%。
A drinking water filtration system with intelligent management functions was designed in this paper. The STC89C58RD＋ was applied as the MCU and the intelligent IC card as security center by using DES encryption algorithm. At the same time, the intelligent management system was designed in Visual C＋ ＋6.0 circumstance. The application shows that this system has the features such as stabili zation, high security, easy to manage etc. The error of the time can be controlled in ls per day, and the standard error of the flow is 0.89%. The system comprehensive errors are less than 1%.
