Abstract

The invention provides a platform of a security communication machine of a temporary speed restriction server. The platform comprises n sets of processors which are operated in pairs. Two processors in at least one set of processor in the n sets of processors are used for synchronously executing data processing operations so as to compare results of the data processing operations. At least one set of processors in the n sets of processors is used for backing up for other sets of processors. The n is an integer which is more than or equal to 2. The data processing results are more precise. Thereliability of the platform of the security communication machine of the temporary speed restriction server is improved. The instantaneity of the temporary speed restriction server is improved.

Description

technical field [0001] The invention relates to the technical field of railway trains, in particular to a safety communication machine platform of a temporary speed limit server. Background technique [0002] The secure communication platform of Temporary Speed ​​Restriction Server (TSRS) can be regarded as a functional module in TSRS. ControlSystem; CTC), Train Control Center (Traffic Control Center; TCC), Radio Blocking Center (Radio Blocking Center; RBC), adjacent TSRS, etc. communicate through secure communication protocols. [0003] The existing temporary speed limit server safety communicator platform adopts two processors based on WinServer or Linux operating system, one of which is used as the backup of the other processor. However, this temporary speed-limiting server safety communication machine platform has low reliability and low real-time performance. Contents of the invention [0004] The invention provides a safety communication machine platform of a tempo...
