High-speed railway traction network fault processing decision-making device based on Ethernet and E1 channel

Abstract

The invention discloses a high-speed railway traction network fault processing decision-making device based on an Ethernet and an E1 channel. According to the device, data interaction is carried out based on an Ethernet and E1 channel communication architecture. The device comprises a central processing and communication plug-in, a panel module, a direct-current power source plug-in, an alternating current and voltage input plug-in, an longitudinal optical fiber interface plug-in, a strong current input plug-in, and a relay outlet plug-in; the central processing and communication plug-in is used for data processing, instruction control and data transmission between the central processing and communication plug-in itself and the other plug-ins; the panel module is used for providing displayand man-machine interface functions according to the instructions of the central processing and communication plug-in; the direct-current power source plug-in is used for providing a direct-current power source for the device; the alternating current and voltage input plug-in is used for transmitting the sampling input of multiple paths of alternating current quantities to the central processingand communication plug-in; the longitudinal optical fiber interface plug-in is used for transmitting data accessed through the E1 channel to the central processing and communication plug-in; the strong current input plug-in is used for transmitting the input information of multiple paths of signal quantities to the central processing and communication plug-in; and the relay outlet plug-in is usedfor providing circuit breaker tripping according to the instruction 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...
