Data flow and data structure design for computer interlocking applied in medium-low speed Maglev

摘要

Computer interlocking (CI) is serving as a core part of operation and control system (OCS) in rail transit, with no exception in medium-low speed maglev transportation system which has almost the same strategy as urban rail transit in train control. Important as it is, the data structure and data flow in CI have to be analyzed in detail just in the system design stage, so as to ensure that it can not only meet the safety-critical technical requirements, but be easier for system upgrade and function expansion as well. Till now, most related research on CI are not based on the medium-low speed maglev application background, moreover, discussion on data flow as well as data structure in CI can also be hardly found. In this paper, data flow and data structure in CI has been analyzed exhaustively according to the specific static and dynamic data transmission and exchanging requirements in medium-low speed maglev, the data structure in signal has also been set as a case with its design in detail also be discussed.
