Introduces a prepayment intelligence cold-water meter computer measurement and info manage net system. By investigating into the info secrecy method of the touch memory card and by experimenting to the high performance porcelain electro motion control valve, and by colligating various technique such as 1-wire bus port design, lowest power waste and battery longevity power supply design, and info database manage design, a tiny mech-electr system with fine performances are 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.
