Detecting and warning system for fireworks warehouse based on wireless sensor networks

For the problem that fast changing of temperature and humidity may cause spontaneous combustion in the process of fireworks warehouse storage, a real-time detection warning system based on wireless sensor network is designed. It collects the current temperature and humidity of the warehouse in real time under the working of temperature and humidity collection model by sensor nodes deployed in hot zone of the warehouse, and it processes the values from temperature and humidity collection model quickly with decision module and upload the values to control center, where the values are evaluated by the control center, after evaluation the center can take real-time scheduling in order to adjust the ventilation adjustment. When the temperature is close to the warning value, Kalman filter prediction module is activated, which will analysis and forecast the temperature trend timely so as to provide accurate quantitative data for operator, and to get early warning, at the same time to be able to play the role of starting fire fighting facilities to fire. Platform for test and simulation experiments show that the system is stable and effective.
