自动报靶机的设计与实现

Modification Method of Correlated Parameters in the Process of Redeveloping of AutoCAD

介绍了一种自动报靶机的软硬件设计，该机具有准确、可靠、造价低、使用方便等特点。主机硬件采用８０３１单片机系统。可显示环数、方位、总环数、总发数等数据，设有外接打印机接口。本机采用远距离串行通讯方式连接采集板与主机，在５Ｖ供电情况下，不加任何升压或调制措施，可在１００～１５０ｍ远的距离上实现信号发送与接收。

It is necessary to do redeveloping work in order to achieve real application due to the AutoCAD is an open type common package. In the process of parts parameterization design, the attention should be taken to the modification of parts correlated dimension parameters. This paper presents a method of parameter modification,solves the modification problem of dimension correlated parameters, gives the common AutoLISP program of parameter modification, and introduces the using method of program.
