Abstract

The invention provides a computer platform based on rail transit, which comprises a first main control board, wherein the first main control board is connected with N first input modules and N first output modules by means of first industrial buses respectively; the first main control board is connected with N second input modules and N second output modules by means of second industrial buses respectively; the N first input modules and the N second input modules are in a parallel redundant relationship; and the N first output modules and the N second output modules are in a parallel redundantrelationship, where in the N is a positive integer. The computer platform can realize the effect of ensuring system integrity while am input / output module cross fault occurs, and further improves thesystem availability and redundancy on the basis of ensuring the system security.

Description

technical field [0001] The invention relates to the technical field of rail transit safety, in particular to a rail transit-based computer platform. Background technique [0002] In the railway signal system, the safety computer platform usually adopts safe algorithmic logic to realize interlocking system, automatic train protection system (Automatic Train Protection, ATP) and other systems, so as to control the train safely. [0003] Currently, a common implementation of a secure computer platform is a two-out-of-two architecture to achieve high availability and security. The two-out-of-two architecture consists of two redundant systems, each with its own logical operation unit, input / output unit, and so on. In each system, two independent central processing units (Central Processing Units, CPUs) form a two-out-of-two voting mechanism to realize fail-safe input and output operations. [0004] When the security computer platform adopting two-out-of-two architecture is runn...
