【摘要】 针对环境信息有线监测存在的问题,设计并制作3个传感节点和1个协调器的多传感器环境信息无线监测网络。提出并编写了1个地址匹配和导引码识别相结合的应用层通信协议,使传感节点与协调器形成1个简单稳定的星形拓扑网络。采用VB和数据库开发了1个具有数据显示、存储查询和控制功能的上位机监测软件,实现了良好的人机交互。经过测试,多传感器环境信息无线监测网络可以在大区域内和复杂环境下稳定、准确地监测环境中的温湿度和光照强度,并可将结果实时显示在上位机监控界面上,实现远程监测。系统可应用于气象环保、煤矿工业、精准农业等领域,具有一定的实用价值和良好的市场前景。更多还原

【Abstract】 A wireless monitoring network of three sensor nodes and a coordinator was developed for multi-sensor environmental information collection,aimed at boosting the problem of wire communication monitoring for environmental information collection.This paper presented and developed the address matches and direct identification code of combining the communication protocol,made a sensor node and coordinator form a simple and stable star topology network.To realize remote monitoring system,it used VB and database develop to a data display,storage inquires the PC monitoring and control software,to achieve the good human-machine interaction function.After testing,the system can be in large area and complex environment stable and accurate monitoring of environmental temperature and humidity and light intensity.The results show that it can realized in the real-time monitoring interface.This system can be widely used in environmental protection,the coal industry and the precision agriculture and other fields,and has certain practical values and good market prospect.更多还原
