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

Abstract

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.

Description

technical field [0001] The invention relates to an integrated structure of a departure indicator of a signal system based on vehicle-ground communication, and is an interface structure between a trackside signal system and a vehicle-mounted system based on vehicle-ground communication. Background technique [0002] In the existing urban rail transit projects, the departure indicator is installed at both ends of the station platform, and the outdoor departure indicator is connected to the indoor power panel and ATS equipment through wired cable transmission. The current signaling system is in the centralized control mode of computer interlocking. Only individual stations are set as equipment centralized stations, and the rest of the stations are non-equipment centralized stations. Generally, 3 to 5 stations correspond to one equipment centralized station. The departure indicator of the non-equipment centralized station needs to be connected to the power panel and ATS equipmen...

AI Technical Summary

Problems solved by technology

The departure indicator of the non-equipment centralized station needs to be connected to the power panel and ATS equipment in the signal equipment room of the station, so ATS equipment must be arranged in the non-equipment centralized station, resulting in an increase in project investment and an increase in the workload of operation and maintenance
