Abstract

The invention discloses a fault processing and decision-making device for high-speed railway traction network based on Ethernet and E1 channel, which performs data interaction based on the communication architecture of Ethernet and E1 channel. The device includes: central processing and communication plug-ins, used for data processing, command control and communication Data transmission between other plug-ins; panel module, used to provide display and man-machine interface functions according to the instructions of central processing and communication plug-ins; DC power plug-in, used to provide DC power supply for the device; AC current and voltage input plug-ins, used to connect The sampling input of multi-channel AC is transmitted to the central processing and communication plug-in; the longitudinal optical fiber interface plug-in is used to transmit the data accessed through the E1 channel to the central processing and communication plug-in; the strong current input plug-in is used to connect multiple The input information of the semaphore is sent to the central processing and communication plug-in; the relay outlet plug-in is used to provide circuit breaker tripping according to the instructions of the central processing and communication plug-in.

Description

technical field [0001] The present invention relates to the field of traction power supply for high-speed railways, in particular to a device with functions of distance measurement and selective tripping of high-speed railway traction network faults based on Ethernet and E1 channel communication architecture, specifically a high-speed system based on Ethernet and E1 channel Decision-making device for fault handling of railway traction network. Background technique [0002] Electrified railways have become the main force of my country's transportation. In the "Medium and Long-term Railway Network Planning (2016 Adjustment)", it is pointed out that by 2020, a number of major landmark projects will be completed and put into operation, and the scale of the railway network will reach 150,000 kilometers, including high-speed railways. 30,000 kilometers, covering more than 80% of the big cities. By 2025, the scale of the railway network will reach about 175,000 kilometers, includin...
