Problems solved by technology

[0005] 1) It is only controlled by a single machine. If the CPU has a hardware failure, the system cannot function normally
[0006] 2) Only a single radio station communicates. If the radio station fails, the data transmission will be interrupted

Abstract

The invention discloses a redundancy control and redundancy communication method and system applied to train tail equipment. Redundancy switching of a control unit is realized through a hardware circuit, seamless control right taking-over of the control unit is realized through a multiplexing technology, main and standby redundancy switching of a communication unit is guaranteed through a redundancy switching state machine, the hot standby redundancy state of the control unit and the hot standby redundancy state of the communication unit can be achieved at any time, and the reliability and usability of the equipment are greatly improved.

Description

technical field [0001] The invention relates to the technical field of railway traffic, in particular to a method and system for redundant control and redundant communication applied to train end equipment. Background technique [0002] It is known that the safe data transmission of the safety end-of-train equipment is realized based on the safety communication protocol SUBSET037. In order to meet the practical application, the internal structure of the end-of-line equipment is divided into a data acquisition unit and a data transmission unit. The data acquisition unit is responsible for the security of the train integrity data. Reliable collection, assume the function of SFM (safety function module) layer, and carry out the protection and transmission of safe data. The data transmission unit only realizes the transparent transmission function of data, and assumes the function of CFM layer. [0003] In the current design of the data transmission unit, a single CPU and a sing...
