Signal system departure indicator integrated structure based on train-ground communication

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 investmen
