The invention provides a
rail transit monitoring system and method. The
system comprises a plurality of monitoring alarm terminals, a
data exchange module and a vehicle-mounted terminal which are arranged along a track; each monitoring alarm terminal comprises a plurality of
image acquisition modules, a plurality of light alarm modules and a first
processing module; all the first
processing modules are connected and communicated through the
data exchange module; each first
processing module is used for identifying whether
foreign matter invasion exists in the image output by an
image acquisition module or not, and transmitting an
alarm signal to the first processing module of the monitoring alarm terminal in front of or behind the monitoring alarm terminal when the
foreign matter invasionexists, so that the light alarm module in a first distance range in front of or behind the monitoring alarm terminal sends a light
alarm signal; the vehicle-mounted terminal comprises an optical
receiver located at the head of the
train and a second processing module. The
system sends out a light
alarm signal through each light alarm module, does not depend on a
signal system to transmit the alarmsignal, and can still effectively transmit the alarm
signal and improve the
driving safety when a
signal communication system breaks down or in a tunnel or other scenes with poor
communication quality.
