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.
