摘要
为了实现大规模、多区域的可燃气体的统一监测预警,使用无线传感器网络自组网技术、通用分组无线业务(general packet radio service,GPRS)无线传输技术和服务器数据库设计了可燃气体报警器采集节点、可燃气体报警器汇聚传输节点并完成服务器云管理平台的搭建.温湿度补偿算法提高了可燃气体报警器的采集精度,多级报警策略使可燃气体预警更智能,数据传输加密算法使数据传输更安全.系统可以应用在居民小区环境对可燃气体泄露智能预警.相关管理部门根据服务器云管理平台对预警信息及时处理并长期对监测数据进行统计分析.最后对搭建的远程可燃气体监测预警系统进行应用测试.结果表明:系统丢包率和用户收到预警信息时间间隔都满足可燃气体预警的实际要求.
To establish a unified platform for combustible gas monitoring and warning in large scale andmultiple regions, the technology of wireless adhoc network and general packet radio service （GPRS）were used to the acquisition node and the convergence transmission node of combustible gas monitoringand warning. Meanwhile, a cloud management platform in a server were built by web and databasetechnology. The algorithm of temperature and humidity compensation combined with multistage alarmstrategy and data encryption made the system more accurate, secure and intelligent. The system has beenused in residential area for combustible gas monitoring and warning. The management department couldalso make immediate decision and analysis data in a long term through the cloud management platform.Application test shows that both the packet loss rate and the time of receiving warning information arecompletely qualified.
