Problems solved by technology

[0002] The current subway traffic dispatching command system will be changed to use the telephone block mode to manually dispatch and command the traffic after the signal system fails. During the command traffic process, it may happen that the traffic dispatcher does not accurately locate the positions of all the trains in the main line section. erroneous telephone blocking order, resulting in a rear-end collision of the train
Therefore, in the current subway traffic command system, when the signal system fails, there is no accurate and intuitive means to reflect the exact positions of all trains on the current line for the traffic dispatching command personnel. Personnel need to confirm the location of the train with the drivers of all online trains and direct them to drive. This will inevitably add a lot of complicated work to the dispatcher, and it will easily cause the dispatcher to miss individual trains and cause major rear-end collisions.

Embodiment 1

[0031] like figure 1 As shown, the present invention includes a signal system vehicle-mounted device, a train position information connection unit, a train-ground wireless communication network system and a control center; Send it to the control center, and distribute it to each terminal after being parsed by the scheduling server of the control center. The train position information connection unit adopts the train network management system or the network connection board of the wireless communication module. The train network management system (train communication bus) provides communication means for all electronic equipment installed on the vehicle.

[0032] like image 3 As shown, the vehicle-ground wireless communication network system of this embodiment includes vehicle-mounted PIS equipment, ground PIS vehicle-mounted equipment, dedicated wireless system communication vehicle-mounted station, dedicated wireless system vehicle-mounted antenna, dedicated wireless syste...

Embodiment 2

[0052] like Figure 4 As shown, the vehicle-to-ground wireless communication network system in this embodiment includes vehicle-mounted PIS equipment, ground PIS vehicle-mounted equipment, interval commercial leaky cables, PIS system-specific interval radio frequency remote units, combiners, PIS system-specific baseband processing units, and PIS system Station exchange, dedicated communication transmission system and, PIS system control center core exchange.

[0053] The vehicle-mounted PIS equipment is connected to the ground PIS vehicle-mounted equipment through the network, and the ground PIS vehicle-mounted equipment converts the train position information into a wireless signal and sends it to the vehicle-ground wireless communication network system through the ground PIS vehicle-mounted antenna. The commercial communication system of the vehicle-ground wireless communication network system The section leaky cable, PIS system-specific section radio frequency remote unit (...

Embodiment 3

[0055] like Figure 5 As shown, the vehicle-to-ground wireless communication network system includes a wireless communication module, an interval commercial leaky cable, a combiner and a mobile Unicom telecom operator network. The train-to-ground wireless communication network system adopts a wireless communication module, which directly edits the train location information into a mobile phone message and sends it, and transmits the train location information to the equipment of each station of the commercial communication system through the commercial leaky cable in the section. The equipment is connected to the wireless network of China Mobile, China Unicom, and telecom operators. The vehicle-to-ground wireless communication network adopts 2G, 3G and 4G communication technologies. The communication frequency bands include 900, 1800, 1900, 2100, and 2300MHz.

Abstract

The invention discloses a train auxiliary monitoring system under the failure state of the rail transit signal system, which comprises a signal system vehicle-mounted device, a train position information connection unit, a train-ground wireless communication network system and a control center; the signal system vehicle-mounted device is connected through the train position information The unit is connected to the train-ground wireless communication network system, and the train-ground wireless communication network system is connected to the control center to send the train location information generated by the on-board equipment of the signaling system to the control center, which is analyzed by the dispatching server of the control center and distributed to each terminal. The present invention can accurately and clearly reflect the exact positions of all current trains for train dispatching commanders under the failure of the signal system, thereby ensuring the train running safety.

Description

technical field [0001] The invention relates to an auxiliary train monitoring system, in particular to an auxiliary train monitoring system under the failure state of a rail transit signal system. Background technique [0002] The current subway traffic dispatching command system will be changed to use the telephone block mode to manually dispatch and command traffic after the signal system fails. During the command traffic process, it may happen that the traffic dispatcher does not accurately locate the positions of all trains in the main line section. In the case of the accident, the wrong telephone block order was issued, which caused the rear-end collision accident of the train. Therefore, in the current subway traffic command system, when the signal system fails, there is no accurate and intuitive means to reflect the exact positions of all trains on the current line for the traffic dispatching command personnel.
