摘要
为解决城市路灯管理中维修效率、实时状态监测、空间分析展示、智能预警响应等问题,采用GIS开发技术、ZigBee通信技术等设计一种可以实现对路灯状态信息实时监控调度、空间信息的展示、智能报警维修、智能应急响应的GIS终端控制系统。经测试,系统实现了预期的设计目标,能安全、稳定、高效地运行,符合功能应用需求。
Based on the analysis of the reasons and harms of oil aging of diesel engines,this paper,taking one kind of diesel engine as an example,analyzes the specific reasons of oil aging and matches a better oil injector by using three-dimensional CFD simulation tool. In so doing,the falling point of fuel jet is improved on the premise that the emission is unaffected,which provides a reference in solving oil aging problem.
