基于温-湿-CO融合传感的棉垛阴燃预警系统设计

Early Warning System Design of Stacking Cotton Smoldering Using Integrated Sense with Temperature,Humidity and CO Concentration

  • 摘要: 棉花是关系国计民生的战略物资,同时棉纤维是各类天然纤维中最具燃烧危险性的一种。依据籽棉垛内部阴燃起火机理,分析选定棉垛火情预警监控要素;研制了基于多传感阵列的籽棉垛温湿度、CO浓度实时监测的阴燃预警与火情防控设备;基于LabVIEW开发了移动电脑上位机数据监控程序。试验证明,系统可以实时监测不规则棉垛内部的温湿度及CO气体信息态,可以为评定棉垛内部状态以及判定棉垛阴燃安全状态提供重要依据。

     

    Abstract: Cotton is a kind of strategic material that affect national economy and people′s livelihood,while cotton fiber is one of the most combustible of all kinds of natural fibers.According internal combustion mechanism of unginned cotton stack,factors of smoldering warning and monitoring of cotton stack were analyzed and selected,smoldering warning and fire control equipment based on multi sensor array for temperature,humidity and CO concentration monitoring were developed,a mobile computer data monitoring program based on LabVIEW was also developed.Test results showed that system could monitor internal temperature and humidity of cotton stack and monitor information of CO gas in real time,which could provide an important basis for evaluating internal state of cotton stack and determining safe state of smoldering of cotton stack.
