粮仓火灾监测预警系统的设计——基于OLS算法结合无线传感技术

Combined with Wireless Sensor Granary Fire Warning System's Design Based on OLS Algorithm

为提升粮库火灾的现代化管理水平,确保粮食生产和存储安全,结合新型物联网技术,设计了粮库火灾预警系统。为此,结合ZigBee、GPRS与无线传感技术等,基于最小二乘法(OLS)对各节点传感器动态采集的离散数据进行分析处理,建立了温湿度等参量随时间的变化曲线,由此判断未来一段时间内粮仓内温湿度等参量随时间的变化趋势,评估火灾发生的风险,达到全天候预警、节约人力、财力支出的目的。通过模拟试验验证,该预警系统运行稳定。

In order to promote the modernization of grain depot fire management level,ensure the safety of food production and storage purposes,combined with the new Internet technology,promoting the modernization of grain depot fire warning system. Is put forward in this paper by using ZigBee and GPRS combined with wireless sensor technology,based on the least squares(OLS) for each sensor node acquisition of discrete data analysis process,establish a formula with reaction time,temperature and humidity and other parameters to judge the granary temperature and humidity within a period of time parameter changes with time,the assessment of fire risk,achieve all-weather warning,save manpower,the purpose of financial expenditure.
