实验室安全监测无线传感器网络应用设计

Application Design of Wireless Sensor Network for Laboratory Safety Monitoring

实验室的安全主要由规章制度与一些技术措施做保障。利用技术手段实时监测实验室环境参数,可及时对危险状况报警。提出一种层次型无线传感器网络,其上层网络拓扑是单向有向通路,下层网络是星型结构。该拓扑结构满足参数检测与数据传输的要求,作为实验室安全监测网络是合理的。本文设计了该网络的路由协议与簇首节点软硬件,该无线传感器网络所用技术成熟,易于工程实现。

The safety of laboratories is mainly guaranteed by regulations and some technical measures.To monitor the environmental parameters of laboratory in real time by means of technology,it can timely alarm the dangerous situation.This article presents a hierarchical wireless sensor network,whose upper network topology is a one-way directed path and the lower network is a star structure.The topology structure meets the requirements of parameter detection and data transmission,which is reasonable as a laboratory safety monitoring network.The article designs the network routing protocol and the hardware and software of cluster head node,and demonstrates that the technology applied in this wireless sensor network is mature and easy to achieve in engineering.
