coal mine dust sensor

Due to the low reliability for coal dust concentration datection and the problem that it is fail to be monitored on-line timely,a new type of dust concentration sensor is studied.A new type of dust concentration measurement system is designed by combining dust concentration sensor and single-chip microcomputer.The system composition,working principle and hardware diagram are described,and the single-chip algorithm procedures are compiled.Finally the real-time on-line detection of dust concentration is realized.When the dust concentration is over the limitation there is an obvious off-gauges audible and visual alarm signal.The system is fast and accurate,and also has the advantages of high sensitivity,stable performance,fixed-point display,and so on.
