The invention provides a
signal system departure indicator integrated
structure based on
train-ground communication. The departure indicator integrated structure is connected to a red-blue network andcomprises a control center communication
server device, a DCS access switch, trackside AP devices, a
train-mounted receiving device and a
train-mounted DMI device. The
signal system departure indicator integrated structure has the beneficial effects that by the adoption of
signal trackside devices and train-mounted device interfaces of
urban rail traffic, no departure indicator is arranged on a platform side, no related cable is laid on the platform side, and train
time table information is wirelessly connected with and transmitted to the train-mounted receiving device through the trackside AP devices; by the adoption of a
wireless transmission mode based on train-ground communication, platform signal devices are reduced, the
system fault rate is reduced by 15%, meanwhile, whole
engineering construction investment is reduced as well, through
estimation, about 80,000 yuan is saved for each
station, and operation and maintenance
work hours are reduced by 3 hours each
station; and the design scheme accords with the development tendency that indoor devices of non-device
concentrator stations are reduced in
urban rail construction, and popularization and reference significance is good.
