Gas monitoring system based on the multi-sensor information fusion

In view of the problem that single sensor can not accurately determine whether the risk or not in common gas monitoring system, a multi-sensor fuzzy information fusion monitoring method is provided based on fuzzy set theory. This method makes obfuscation for the information obtained by multiple sensors of monitoring equipment and then makes fusion to obtain accurate state estimation of equipment. It makes a design for the system´s overall structure and the hardware composition of intelligent node, simultaneously, it makes experimental tests. The experimental results show that: the method makes full use of multiple information provided by sensors to improve the recognition rate and reduce disaster.
