摘要
高校多媒体教室用的投影灯泡是使用和更换比较频繁的昂贵耗费品,需要一个能及时掌握投影灯泡运行时间的方法。文中利用面向云服务的编程思想,并以网络中控升级改造为契机,实现了投影灯泡运行时间累计计时、设限触发、消息推送、采购报送等一系列主动更新的全过程。实践表明,以此方法实现的投影灯泡主动更新,为多媒体教室设备管理和维护提供了新颖的方法。
Projector lamp is the kind of frequently used and replaced consumable in multimedia classrooms,hence,measures are needed to monitor the running time of lamps which are rested on projector. Through the use of cloudservices oriented programming ideas,this study successfully achieved a series of active updating processes,including actively time accumulation,condition-limited trigger,message push and purchase orders delivery,by the chance of network control system upgrading. The practical trials show that this paper provided a novel method for the management and maintenance of multimedia classroom equipment.
