文摘The ad lamp-box controller is designed in consideration that ordinary urban ad lights usually remain lit through the night and a specially assigned staff needs to be on duty to control their switches.It can be automatically controlled with a photo resistance testing the day and night as well as a CD4060 chip controlling the length of time interval between switching the ad lamp-boxes on and off.In this way,both energy and labor can be saved with the controller.It is matching with the target of"constructing a conservation-minded society"in our country and deserves to be promoted in market with its practical significance.
文摘车灯花纹具有单元尺寸小、单元结构类似、单元数量多和造型精度要求高等特点,手工建模要花费大量时间,效率极低。针对上述问题基于NX10二次开发平台,开发异形四棱锥车灯花纹的快速建模系统。首先利用人机交互界面定制模块(Block UI Styler),定制出风格统一的UI对话框。其次,对用于创建花纹单元的曲线网格进行处理:通过曲线之间的相交关系将曲线分为2组,创建交点并通过矩阵变换对交点排序得到交点矩阵。最后利用应用程序接口(NX Open API)函数,结合异形四棱锥花纹的手工建模思路,实现异形四棱锥车灯花纹的快速建模。实践证明,异形四棱锥车灯花纹快速建模系统可以提高建模效率,缩短车灯的设计开发周期。
