摘要
森林资源是世界最宝贵的自然资源之一,森林火灾预防和监测比扑灭更具现实意义。为了预防和减少森林火灾对自然资源造成的巨大危害,设计并开发了基于ZigBee的森林火灾智能监测系统。该系统可以完成烟雾浓度、降雨量、空气温湿度和土壤湿度这四种环境参数的采集和处理,且其传感器模块具有易扩展性。系统采用基于六边形的控制部署方式和多协调器来代替传统一对多的拓扑结构,使系统具有覆盖面积广、低功耗和高可靠性等优势。森林防火系统硬件电路设计简单、可集成度高和可扩展性强。系统节点的软件设计结构合理,数据通信采用组播的方式,传送过程中对数据加入辨别标志以保证其安全可靠。同时,所设计的系统监控界面具有简洁、适用和可操作性强的特点。该系统已实现批量生产,并进行了实地试验,性能稳定,可推广使用。
Forest resource is one of the most valuable natural resources in the world. Prevention and monitoring of the forest fire is more realistic than extinguishing the fire. In order to prevent forest fires and to reduce the enormous harm caused to natural resources,the intelligent forest fire monitoring system based on ZigBee has been designed and developed. Four kinds of environmental parameters can be collected and processed by this system,including smoke concentration,rainfall,air temperature and humidity,soil moisture,and its sensor modules are scalable. The hexagonal control deployment and multi-coordinator are adopted to replace the traditional one-to-many topologic structure,thus the system possesses advantages of wide coverage area,low power consumption and high reliability. In this system,the design of hardware circuitry is simple,highly integrated and scalable. The software design of the system node is reasonable,and the data communication is carried out by the way of multicast,and in the process of data transmission,the identification mark is added for data,to ensure its safety and reliability. In addition,the monitoring interface in this system has the characteristics of simplicity,applicability and operability. The system has been fabricated in batch and tested on site with stable performance. It can be promoted to use.
