Embodiment

[0049] Such as figure 1 Shown, a kind of subway train anti-collision early warning system, this system is connected with the running safety device 5 of train, comprises catenary 1 and vehicle-mounted equipment erected along train track.

[0050] Since the catenary of rail transit is insulated in sections, a phase splitting device 12 must be installed at the section insulation first to ensure that the carrier signal can be transmitted without interruption in the catenary 1 and can isolate power frequency interference.

[0051] The on-board equipment is arranged on the train, including a coupling module, a signal processing module and an early warning display module 4 connected in sequence. Among them, the coupling module includes two couplers 2, which are coupled with the catenary 1 to collect or send carrier signals. Since the couplers 2 may be located at the segmental insulation, they cannot send and receive carrier signals, so the two couplers 2 are as follows: figure 2 As...

Abstract

The invention relates to an anti-collision early-warning system for subway trains, which comprises an overhead contact system and a vehicle-mounted device, wherein the overhead contact system is erected along a train track, and a graded insulation part of the overhead contact system is provided with a neutral-section passing device; and the vehicle-mounted device is arranged on a train and comprises a coupling module, a signal processing module and an early-warning display module which are sequentially connected, wherein the coupling module and the overhead contact system are coupled so as to acquire or send carrier signals, and the signal processing module and the early-warning display module are both connected with a traffic safety device. The method comprises a sending process and an acquisition process which are synchronously performed, and the real-time traffic information is obtained through sending and acquiring information in the overhead contact system by using carrier signals. Compared with the prior art, the system and method disclosed by the invention can realize two-way communication, and are not easy to be disturbed; and the communication coverage distance is far larger than that of the existing wireless communication system.

Description

technical field [0001] The invention relates to an urban rail transit signal system, in particular to an anti-collision warning system and method for subway trains. Background technique [0002] The urban rail transit signal system is the key system equipment to ensure the safety of train operation, realize the modernization of traffic command and train operation, and improve transportation efficiency. [0003] The urban rail transit signal system usually consists of the automatic train control system (Automatic Train Control, referred to as ATC), and the ATC system includes three subsystems: [0004] Automatic Train Supervision (ATS for short), [0005] The automatic train protection subsystem (Automatic Train Protection, referred to as ATP), [0006] Automatic train operation system (Automatic Train Operation, referred to as ATO). [0007] The three subsystems form a closed-loop system through an information exchange network, realizing the combination of ground control ...
