单片机在硬币辨识及智能投币箱系统中的应用

The Application of MCU to Coin Discerning and in the Smart Coin Box Project

文章介绍了应用单片机对金属硬币进行辨识的原理及其在智能投币箱系统中的具体实现,讨论了在硬币检测及智能投币箱系统设计中一些易被人忽视而却十分重要的问题。

This paper introduced the principle of discerning the authenticity of coins with a MCU system and the realization in the Smart Coin Box Project. Moreover, some subtle but crucial problems are also discussed, which are found in the process of designing a coin-discerning system and Smart Coin Box Project.
