基于推技术的网络化监控报警系统

Monitor and Alarming System over Internet Based on Push Technology

以LonWorks智能节点为现场层的实际工程为例,阐述网络控制系统的结构,探讨其中的关键技术。研究基于事件驱动的push技术,介绍了Java报警服务器。考虑网络带宽的限制及控制系统的实时性要求,在报警系统中采用推技术减轻网络中的信息拥塞、时延等问题,有利于网络化控制系统的稳定性。

This paper presents a general framework for network control systems, where all Lonworks smart nodes are assumed to be connected through a communication network. On the base of analyzing the monitor and control network system, it introduces the event-drivent push technology in alarming system and Java server. With the limit of network band width and network real-time required on control systems, the design with the push technology can reduce network congestion and network delay then the stability of the network control system is much better.
