摘要
良好的核心机房环境条件对于各类园区网络的正常运行至关重要,因此配备环境监测系统已经成为核心机房的一项必备措施。针对传统监测系统布线的灵活性差等问题,本文提出了一种具有能量感知的节能无线传感器网环境监测系统。节点设计采用Jennic公司的JN5139 SOC芯片,集成编译环境采用开源软件Code::Blocks,其内部运行由简单任务调度器BOS来统一管理。最后结合本单位核心机房实际情况,经过实际测试,给出了恰当的节点布置方案、节点节能发射功率值,实现了能量监测预警功能。此方法不仅可以用于机房环境监测,对于其他环境监测,如现代化养殖场的环境监测同样适用。
A good environmental condition of the core computer room is very important for the campus networks. Therefore it is necessary to outfit the enviromnental monitoring system for the core computer room. But the traditional monitoring systems have some problems： for example the poor flexibility of wiring problems, the high cost and so on. According to this situation, this paper proposes an energy-aware and energy-saving monitoring system for the core computer lab environment by means of wireless sensor networks. The design of WSN nodes adopts the SOC JN5139, the integrated compiling environment adopts open source software-code： ：blocks. When the node runs, it is controlled by the BOS. At the end, the experiments are done in the core computer room with the nodes, the proper scheme of the nodes distribution and the value of energy-saving transmit power are given, in this way the intelligent monitoring system has the ability to achieve the monitor. At the same time, the monitoring systems can be used in the modem farm and the other environment.
