简介:摘要随着铜价的飞涨,国内非法收购金属铜的价格也居高不下,在利益的驱使下,不法分子往往铤而走险,大肆盗窃通信电缆。各电信运营商不得不成立专门的护线队,为此投入了大量的人力物力,但效果并不理想,往往在接到报警赶到现场时,盗贼已逃之夭夭,电缆也不知去向。本文通过在传统回路防盗的基础上,通过整合电信运营商的相关资源,实现了一个通信电缆定位防盗报警系统,较好的解决了电缆被盗及时报警,被盗地点准确定位和事后被盗通信电缆追踪的问题。
简介:摘要针对内外饰零件的结构匹配特点以及目前零件在检具上的尺寸检测结果与实车装配效果存在差异的现象,本文通过实例简要介绍了带卡扣、卡钩、筋条的这几类零件模拟环境件进行定位设计和检测设计的方法,并提出了一种新式的、组合环境件进行定位和检测的设计方案。AbstractForinterior/exteriorpartswithclips/ribs袁themethodoflocatingandcheckingwhichsimulatesthematingpartsisintroducedbysimpleexamples,basedonparts'complexmatchingstructureandsomedimensioncheckingresultsforpartsbeingnotconsistentwiththeirmatcingstatusonthevehicle.Andanewlocatingandcheckingmethodbycombiningmatingpartsisproposed.
