Research on unmanned electro-acoustic composite dust concentration monitoring network system based on C-MBUS

Combustible dust concentration reaches the concentration limit is one of the sufficient conditions for dust explosion, thus monitor of dust concentration is an effective way to prevent the occurrence of disaster, and however, there is no combustible practical technology for real-time detection of dust concentration. To solve this problem, an unmanned “acoustic - electric” composite detection program that is base on C - MBUS bus is propose, and complete the design for mixed system structure. The concentration monitoring network system and the two data fusion model are propose by analyzing the advantages of C-MBUS bus technology and data characteristics of composite detection system. Making multi-sensor data fusion that based on Kalman filter algorithm, using the semi-physical simulation to simulate the capacity test of the C-MBUS bus communication network. Finally, the monitoring network system of unmanned combustible dust concentration is form. The experimental result shows that it can meet the needs of the monitoring of industrial dust concentration with unmanned, real-time, rapidly and accurately by using the unmanned density monitoring network system in this paper that based on the C-MBUS bus.
