In the work, a kind of low power, multi-parameter composite fire detection node is designed, which can detect temperature, smoke concentration and CO gas concentration. And combining with the WSN (wireless sensor network), a real-time wireless fire monitoring system is established. This system is applied in fire detection of special circumstance represented(More)
A kind of ultra-early fire detection system with high sensitivity and multi-parameter is introduced. The hardware of the system comprises smoke detecting module, CO gas detecting module, temperature detecting module and processing module. Optical measurement room of smoke detecting module is designed specially; it serves as a collimating and beam expanding(More)
The theory and methods of MODIS(Moderate Resolution Imaging Spectroradiometer)data in fire detection are introduced. Experience with high quality data from MODIS has suggested several improvements to the original active fire detection. An enhanced algorithm using variance between-class and smoke plume mask is described. The brightness temperature threshold(More)
