Line-side electronic unit with configurable contact information and implementation method thereof

Abstract

The invention discloses a line-side electronic unit with configurable relay contact information and an implementation method thereof. The line-side electronic unit comprises an acquisition input module, a management configuration module and an output module; the acquisition input module is used for dynamically acquiring multi-path switch quantity input conditions, converting expanded multi-channelparallel port data into serial data by means of a parallel-serial conversion mode, and parsing the input conditions; the management configuration module is used for managing the input conditions, configuring the data and conducting management allocation on contact information corresponding to any transponder output channel through a configuration file; the output module selects corresponding messages according to the allocated valid contact information, encodes the messages and outputs the encoded data to corresponding transponders. By means of the line-side electronic unit with the configurable contact information and the implementation method thereof, four paths of different transponder messages can be simultaneously output to the four ground transponders without mutual influence, the safety of a system is ensured, and meanwhile, the corresponding relationship between input switch quantity information and output channels can be flexibly configured.

Description

technical field [0001] The invention relates to the fields of data security and railway signals, in particular to a ground electronic unit with configurable contact information and a realization method thereof. Background technique [0002] The ground electronic unit (Line-side Electronic Unit, referred to as LEU) is used as the ground equipment for the interface between the train control center and the active transponder, and is used to transmit variable information data to the active transponder. A certain amount of transponder message data and other small amount of necessary configuration information need to be stored in the LEU to meet the needs of transponder uplink data transmission. like figure 1 As shown in , the configuration information includes: mask value configuration, judgment parameter configuration and channel switch configuration. [0003] The transponder message data are all stored in FLASH, when a message switching command is generated, the new message ...
