为减少市面上假硬币的的流通，提出一种基于ARM的硬币鉴别系统设计。这个测试系统是一个复合测试系统，使用4个传感器，包括电容传感器、电磁传感器、涡流传感器、光学传感器检测检测硬币的材质，厚度，直径信息。系统的信号采集电路以AD9480为主，实现硬币特征量的高速高效采集处理。采集处理后的硬币特征数据送入STM32，通过与其真币特征值的比较来实现硬币的鉴别。实践表明，该系统达到了预期目标。

In order to reduce the false coin circulation,a design of coin identification system based on ARM is presented in this paper. This is a composite testing system,in which capacitive sensor,electromagnetic sensor,eddy current sensor and optical sensor are used,to detect the material,thickness and diameter of coins. The signal acquisition circuit system is based on AD9480 to realize high-speed and efficient acquisition and processing of coin features. The processed feature data of coins is sent to STM32 to compare the data with true coin values to identify the detected coins. This system has a great market prospect.
