摘要
针对传统的分布式监控系统存在通用性和现场适应性差以及系统安装调试难度大等不足,采用嵌入式芯片LPC2292、无线射频芯片nRF905、实时操作系统μCOS-II和任务限时服务及协议转换中间件技术,设计了一种嵌入式数据集中器,实现了各种类型的现场终端数据的无线接入,较好地解决了当前分布式监控系统存在的上述问题.将该集中器用于电力开关室环境监测等系统中,应用结果表明该集中器具有与现场终端适配方便、扩展灵活、安装调试简便、工作稳定可靠等优点.
In view of the existing lack of versatility and adaptability as well as on-site system installation and debugging difficulty in traditional distributed monitoring system,this paper using embedded chip LPC2292,wireless RF chip nRF905,real-time operating systemμCOS-II,task time-limited service and protocol conversion middleware technology to design an embedded data concentrator,it realizes the wireless access terminal site data types and can solve the existing problems of distributed monitoring system.The concentrator has been used for the environmental monitoring system of electric power switch house,the application results show that the concentrator with the terminal adapter is convenient,flexible,convenient installation and debugging,work stable and reliable.
