3 . based on the unattended grounded sensor networks , the sensor configuration for a static target and moving targets are discussed , which show that sensors distributed uniformly on a circle is suitable for sensor networks initialization 以無人監視地面傳感器ugs網絡系統為背景,分析了針對靜止目標的點優化布局和針對運動目標的面優化布局,得到了傳感器均勻地分布在圓周上是較好的網絡初始化布局的結論。
This project develops a three - dimensional cad system module for electric switch cabinet . it is based on unigraphics nx ( ug nx ) which is a integrated cad / cae / cam software of ugs corporation of american and visual c + + 6 . 0 which is a classics programming software of microsoft corporation , the project has a further study in it by synthetically using a series of development methods and electric switch cabinet ’ s serialized characters : complex structure , tight time limit for a project and big workload . the author has mainly carried on the following researches in this paper : studied the solid modeling of ug nx thoroughly , including the application of solid modeling , express and parameter - driven modeling 本課題是在windowsxp平臺上,基于美國ugs公司的cad / cam / cae一體化軟件unigraphicsnx ( ugnx )和microsoft軟件公司的經典編程軟件visualc + + 6 . 0 ,利用ugnx良好的開放性,通過一系列的二次開發方法的綜合運用,針對電氣開關柜結構復雜、工期緊、工作量大、部分零部件已經系列化等特點,開發出了專用電氣開關柜三維cad模塊。
