现实工艺与生活中，普通的物理控制方案逐渐不能满足科技需求，逐一被淘汰，若采用现阶段发展成熟的智能控制方案可以技术发展需要。在产品的可靠性、安全性、便捷性和维护简易来看目前的充电桩计费系统是不能满足要求，因此运用智能控制器开发充电桩计费系统可以解决目前产品所在的问题，本设计系统运用ST公司MCU平台进行研究。
实现功能如下：
1.本设计系统通过IC卡注册新号，然后可以录入指纹，LCD1602液晶屏显示系统运行信息；当注销IC卡片，需要验证指纹，其中一个指纹正确才可成功注销；
2. 系统可以实现对卡片进行充值。系统掉电后IC卡内金额不消失；
3. 对三个充电桩进行选择；充电桩选择完选择三个充电时间和金额（1min 1rmb，2min 2rmb，3min 3rmb）；
4. 选择好充电桩和充电时间后，刷卡并验证指纹（其中一个正确）后开始充电；
5. 充电时，刷完卡验证完指纹后如果金额不足蜂鸣器报警；时间到后继电器断开表示充电完成。
