新型自动装弹机的研制
摘  要：本系统设计主要完成用单片机取代原自动装弹机中的所有继电器，由单片机软件逻辑控制输出。单片机的输出通过TTL电平控制IGBT管的基极，用IGBT管去驱动相应的电机和指示灯其它被控件。采用MCS-51系列单片机。又选择8051芯片。替代了原装弹机中的许多继电器，而用软件实现其控制功能。这是该设计的主要之处。硬件驱动和抗干扰也是本设计的重点。论文中介绍了原自动装弹机，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，并说明了该系统软件设计的方法以及其功能的实现。本系统是通过信号输入、逻辑计算、再做出正确的输出。采集信号时，因为开关量信号，为了抗干扰本系统软件设计中采用了抗干扰措施。
DSP芯片，也称数字信号处理器，是一种特别适合于进行数字信号处理运算的微处理器，其主要应用是实时快速地实现各种数字信号处理算法。DSP控制器是一款高性能的单片机。DSP控制器的总体结构：一是采用多组总线结构实现并行处理机构，允许CPU同时进行程序指令和存储数据的访问；二是采用独立的累加器和乘法器，使得复杂的乘法运算能快速运行；三是累加器和乘法器分别连接了比例移位器，使得许多复杂运算或者运算后的定标能在一条指令中完成；四是有丰富的寻址方式，可方便灵活地编程；五是有完善的片内外设，可以构成完整的单片系统。本设计的发展前景是可以采用数字信号处理器DSP代替8051芯片。将更为简单和快捷。

The study of new automatic belt loading machine
ABSTRACT：It removed all relays in the original system, and substituted with the single chip micro-controller in this system. The single chip micro-controller controls the base of the IGBT tube by extremely, again actuates the corresponding electrical machinery by the IGBT tube. This design uses the MCS-51 series single chip micro-controller 8051 chips. It has omitted many intermediate relays in original system, and realized its function by software. This is the innovation place of the design.
 In the paper, I introduced the original automatic feed mechanism, analyzed why had to carry on the technological transformations to the original automatic feed mechanism, introduced the component of the new automatic feed mechanism, and explained the method of this software design and its function realization. Through the effective gathering signal, the correct judgment signal, this design makes the correct output. When gathering signal, because of being the switch signal, I has used the method of gathering many times for ant jamming in this design.
 The DSP controller is a section high performance single chip micro-controller. The structure of the DSP controller has many places: The first, it uses the multi- groups bus structure for realization parallel processing, allows CPU carry on the program instructions and the stored data simultaneously; The second, it uses the independent accumulator and the multiplier, enables the complex multiplication operation become the quick operating; The third, the accumulator and the multiplier have separately connected with proportion shifting, that can complete many complex operations or the operation calibrations in an instruction after caused them; The forth, the way of looking for address is rich, that enables making programs become more easily; The fifth, there is the consummation outside to suppose internally, may constitute the integrity chips system. This design prospects for development are using digital signal processor DSP replacing 8051 chips. Will be simpler and more quickly.
