基于USB接口的智能饮用水机研究

Study on USB Interface Based Intelligence Drinking Water Machine

针对目前普遍使用的带有IC卡的智能收费饮水机存在的无法判别水质过期和不能根据饮用水机供水速度而自动调节供水单价等功能缺陷,提出了改进方案,设置了供水流量和速度检测装置,增加了供水单价调节模块和限制供水机构,也增加了USB接口电路,满足通信和扩展功能。

Aiming at the functional shortcomings existed currently in widespread use of intelligence drinking water machine with IC card, which cannot identify the expiration of water quality and cannot adjust water price according to the speed of drinking water supplying, etc., this paper puts forward the improved plan which establishes the monitoring devices for fluid volume and speed of water supplying and adds the modules for the unit price adjustment of water supply and the device for limiting water supply, and also adds the USB interface electric circuit, satisfying the communication and function expansion.
