摘要
探讨预付费智能卡式冷水水表及其控管网络系统设计中的关键技术,从存储信息载体的信息安全性和执行机构的动作可靠性这两个技术难点着手,通过对TM卡信息保密机制的研究和具有独特性能的陶瓷电动控制阀门的研究试验,并应用I2C、1-wire总线技术进行控制器软硬件设计,应用表面贴装、器件绑定、最小功耗设计与电池长效供电等多项技术进行整合,设计微机电一体化系统,研究表明,合理优化存储信息载体的信息安全机制、检测和执行机构的动作可靠性,对提高微机电系统在计量控制精度、低功耗特性、数据保密性、动作可靠性等方面的性能具有重要作用。
Study the key technique to design prepayment intelligence cold - water meter and its info management system, take measure with the two technical nedus of info carrier＇ s security and executive machine＇ s action credibility, by investigating into the info secrecy method of the touch memory card and by experimenting to the high pedormance porcelain electro motion control valve, a tiny mech - electr system is designed. I^2C bus and 1 - wire bus technique are used in controller hardware ＆ software design, and by colligating various technique such as surface stick installation, parts of apparatus tied, lowest power waste and battery longevity power supply design, a tiny mech - electr system with fine effect is obtained. The study indicates that optimizing on the info carrier＇ s security mechanism and on the inspect ＆ execute machine＇ s action credibility plays importance in improving the tiny mech - electr system＇ s performance at measure ＆ control precision, power waste, data secrecy and action reliability.
