The traditional coin storage devices can simply be stored on the coin does not have automatic counting function and determine the authenticity of the coin. In view of this situation for electronic coin storage systems research. Change coin currency design uses recognition technology to identify the authenticity STC89C52 using SCM technology to information processing, and display the total amount of memory, and the amount of current investment currency. The design consists of four parts supply circuit, microcontroller control circuit, coin identification circuit coin supply and driving circuits. Keil programming software uses and use Protus software to hardware and software simulation results show that the system of high sensitivity, stable performance, with coin recognition, verify the authenticity, counting display. Keywords: Coin recognition; Electronic save money; Authenticity of identification; STC89C52 III 目录绪论................................................................................................................................ 1 1研究背景及意义........................................................................................................ 1 研究背景............................................................................................................. 1 研究意义............................................................................................................. 1 国内外研究现状...................
