摘要
博物馆内展柜数量众多,且展柜中用于监测微环境的传感器和仪器类型也种类繁多,使用数字化设备集中监控展柜微环境各项参数是趋势;设计无线网关,收集展柜内各仪器和传感器测试数据,再转换成无线数据对外发送,统一了展柜内传感器和仪器对外数据交换方式;再以C/S架构为基础,使用基于优先队列的通信代理机制,集中管理通信消息,并通过堆有序对优先队列进行优化,实现了服务器在系统中的通信调度功能,解决了文物保护系统中因保护需求多样化导致的通信方式难以兼容的问题,取代了原有的依靠人工巡检来核查微环境保护数据的繁琐工作,提升了效率和稳定性;实践证明,该系统在北京故宫等博物馆运行正常,通信功能稳定,可靠性好,满足博物馆微环境保护需求。
There are a large number of showcases in the museum,there are also various types of sensors and instruments for monitoring the micro-environment in the showcases.The use of electronic equipment to centralize monitoring micro-environment parameters is the trend.A wireless gateway was designed to unify the showcase external data exchange：It collect the communication data of each instrument and sensor in the showcase,and then it converts RS485 data to wireless data to send out.The priority queues based communication agent mechanism also play an important role to achieve communication dispatching function of the C/S architecture system.It realized centralizing management of communication messages,then using heapsort algorithm optimizes priority queues.Through using those methods,the dispute of incompatible communication problems caused by diversified demands in micro-environment protection system settled.And it replaced the original rely on manual inspection to verify the micro-environment protection data,improved efficiency and stability.Practice has proved that the system works well in many museums like the Imperial Palace,and the system communication mechanism is stable and reliable,which can better meet the needs of the museum micro-environment protecting demands.
