The invention relates to a mine
smoke intelligent early warning device,
early warning system and early warning method. The device is characterized in that an
aerosol measuring light chamber, a particle high-efficiency filter, a
trace gas monitoring chamber and a piezoelectric
micropump are sequentially mounted in an inner cavity of an outer shell from front to back; a 650nm
laser source, a first detection
assembly, a 450nm
laser source, a second detection
assembly, a 850nm
laser source, a third detection
assembly and a temperature sensor are respectively arranged in the
aerosol measurement light chamber; a
piezoelectric quartz crystal detection matrix, a
quartz wafer oscillation module and a high-precision frequency measurement module are arranged in the
trace gas monitoring chamber; according to the
system, a central
server is respectively connected with a visual
client and a plurality of mining
smoke intelligent alarm devices; the method comprises the following steps: monitoring a plurality of monitoring areas by using a plurality of mining
smoke intelligent alarm devices; and the central
server processes the
monitoring data and outputs a monitoring result. The device, the
system and the method can accurately monitor smoke in a working place in real time.
