摘　　要：针对目前电子支付普及导致硬币堆积、金融资源浪费的问题,基于数字电感传感器辨伪、红外传感器计数设计了一种辅助硬币回收系统。系统采用树莓派作为主控制器,由硬币辨伪、计数统计和交互显示等模块组成。以一元硬币为测试对象,系统通过大量的实验测得:硬币鉴别准确率为100%,计数准确率为99%以上,达到了沉积硬币智能化、自动化回收的目的,促进绿色金融发展。In order to solve the problems of coin accumulation and financial resource waste caused by the current electronic payment method,a system for assisting coin recovery was designed.The system uses a digital inductance sensor based on electromagnetic induction as the principle of discrimination and an infrared sensor for counting.Raspberry Pi is used as the main controller,which is composed of coin identification module,statistical module and interactive display module.Taking RMB one yuan coin as the test object,the system has measured through a large number of experiments:the coin identification accuracy is 100%,and the counting accuracy is more than 99%.It has achieved the purpose to intelligently and automatically recover coins deposited in society,and has high application value for promoting the development of green finance.
