Title:
SAFETY COMPUTER SYSTEM FOR USE IN TRAIN CONTROL
Document Type and Number:
WIPO Patent Application WO/2017/107665
Kind Code:
A1
Abstract:
A safety computer system for use in train control, comprising a first system (101) and a second system (102) that are mutually redundant. One of two system processing modules (104 and 107) serves as a primary processing module, while the other one serves as a backup processing module. Two system input modules (103 and 106) respectively are configured to capture an external signal, to perform a two out of two voting, and to stop working when the two out of two voting did not pass. The primary processing module and the backup processing module respectively are configured to process input data coming from a same system and to perform a two out of two voting, when the two out of two voting of the primary processing module did not pass, then the primary processing module stops working and switches over to the backup processing module having passed the two out of two voting for subsequent processing, and the backup processing module thence becomes the primary processing module. Two system output modules (105 and 108) respectively are configured to verify the validity of the data processed by the primary processing module, to perform a two out of two voting, and to stop working when the two out of two voting did not pass.
