摘　　要：无操作系统的纸币识别接收器仍占市场的主流,功能扩展性方面比较有限,将μC/OS-Ⅱ实时嵌入式操作系统移植到8位51单片机上来开发纸币识别接收器,提高了系统可靠性和功能扩展性.根据实时性的要求设计了关键的数据收集电路,根据系统工作原理将功能详细划分为任务,整个软件系统经编译调试能满足预定要求.The bill acceptors without Operating System are still the mainstream product in the market. This kind of acceptors is limited in the functional extension. By porting the Real-Time Operation System to the 8-bit single-chip microcomputer to design the bill acceptor, the reliability and functional extension of the system are improved. The key circuits for data acquisition were designed and the function was divided into several tasks which can communicate according to the principle of the system in detail. After Compiled and debugged, the whole software system can satisfy what we demand before.
