摘  要：本文介紹了一種基于單片機的新型彈藥自動裝填系統。分析了為什么要對原自動裝彈機進行技術改造，介紹了新型自動裝彈機所選的器件，并說明了該硬件設計的方法以及其功能的實現。該系統簡稱新型自動裝彈機，以計算機控制系統的理論為基礎，以MCS-51系列的8051單片機為核心，并外加輸入和輸出電路；主回路功率開關器件采用IGBT，再由IGBT管去驅動相應的電氣元件。實現了通過有效采集信號、正確判斷信號、再做出正確的輸出。
原自動裝彈機是繼電器控制系統，由于本身采用固定的接線形式，沒有通用性和靈活性，在工藝要求提出后才能制作，不能實現系列化生產，同時也容易燒壞觸點，造成開關動作不可靠，維修不方便等缺點，因此須進行改造。
新型裝彈機系統采用的芯片是MCS-51系列單片機的8051芯片。省去了原裝彈機中的許多繼電器，而用軟件實現其控制功能，這是該設計的創新之處。實驗結果證明此設計有較強的控制效果和較強的實用性。

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.
