Decentralized Gas Detecting System Based on Multi-sensor Information Fusion

The existing gas detecting instrument can't detect the leaking out of the poisonous or flammable gas. To ensure the safety of production and scientific management, it is very important to develop a detecting system suitable to the leak out of the poisonous or flammable gas. A general architecture of the distributed on -line gas detecting system is proposed. The adaptive weighted fusion algorithm is presented. At last, an application example is introduced, the research results show that the identification of the system is precise. It not only solves the problem of the gas cross sensitivity, but also helps to realize the artificial intelligence and multifunction.
