摘  要：本文介绍了一种基于单片机的新型弹药自动装填系统。分析了为什么要对原自动装弹机进行技术改造，介绍了新型自动装弹机所选的器件，并说明了该硬件设计的方法以及其功能的实现。该系统简称新型自动装弹机，以计算机控制系统的理论为基础，以MCS-51系列的8051单片机为核心，并外加输入和输出电路；主回路功率开关器件采用IGBT，再由IGBT管去驱动相应的电气元件。实现了通过有效采集信号、正确判断信号、再做出正确的输出。
原自动装弹机是继电器控制系统，由于本身采用固定的接线形式，没有通用性和灵活性，在工艺要求提出后才能制作，不能实现系列化生产，同时也容易烧坏触点，造成开关动作不可靠，维修不方便等缺点，因此须进行改造。
新型装弹机系统采用的芯片是MCS-51系列单片机的8051芯片。省去了原装弹机中的许多继电器，而用软件实现其控制功能，这是该设计的创新之处。实验结果证明此设计有较强的控制效果和较强的实用性。

ABSTRACT：This artic introduced a kind of automation system which according to SCM(Single Chip Micyoco) of pack cannonball to fill the system automatically, the system brief name is ASPC(Automation System of Pack Cannonball). Analyze why want the realization of the method to ASPC to carry on the technique reformation at first, introduce newly ASPC's circuitry, and explained that hardware design and its function. That system with the foundation of calculator controls theories, take 8051 SCM of the seriates MCS-51s as the core, and in addition input and output electric circuit; the main circuitry power switch is IGBT, and IGBT drives the homologous electricity component.
Early ASPC formed with electric appliances, because of its line form, have no in general use and vivid, then it cannot be modified after craft request sued, and cannot making systematic production, burn easily also and easily bad touch the point, result in switch's action not dependable, maintain inconvenient etc., so carry on the reformation is important.
New ASPC used 8051 chipsets of SCM of seriates MCS-51s. it retrenched many electric appliances of early ASPC, and used software to control its functions; this is a creative design. The result of experiment proves that the design contain stronger control result and stronger function.
