Automatic train operation (ATO) system is one of the important components in advanced control systems. Ideal controllers are expected for automatic driving function ATO Aiming at intelligence requirements systems, an NSGA-II-based parameter tuning method fuzzy immune PID (FI-PID) controller and a grey model GM(1,1)-based (FGI-PID) were proposed. Taking maglev train’s as object velocity-time curve input, feasibility FI-PID applicability FGI-PID tested. The results showed that optimized...
Abstract The safety of equipment operation is important for the rail transits. lifetime and its improvement methods have become one key issues in maintenance Based on fuzzy comprehensive evaluation process result data, decision-making algorithm improving was discussed, including strategy recommendation based assessed data matching case reasoning. Taking actual onboard ATC Line 11 a city as an example, effectiveness two verified. study can support departments.
Auxiliary stopping area (ASA) is the necessary emergency facility for train safety of normal high-speed maglev. The study addresses ASA layout problem maglev operated bidirectionally on single track. First, an optimization model unidirectional double-track lines considering safety, operation efficiency, and construction cost established, two basic methods are investigated based distance demand characteristic ASAs. Then, bidirectional single-track analyzed, two-way coordination algorithm...
As the key part of metro trains, on-board automatic train control (ATC) systems play functions operation preventing speeding. Aiming at problem lifetime status evaluation in life cycle management ATC equipment, an indicator system influencing factors and model were established, a cloud model-based method for equipment was proposed. Combined with practical case line Shanghai, applicability verified, targeted maintenance suggestions given. It is expected to provide reference ideas methods rail...
Operating scenarios have important value in the development and operation of rail transit systems. Based on literature search results, concept operating is discussed firstly. Then, taking railway, subway, tram, maglev as objects, status, control systems them are described. Furthermore, basic composition transits analyzed, typical characteristics given, discussed.
Auxiliary stopping area (ASA) is the key guarantee for high-speed maglev train operation safety. Aiming at layout of ASA along track, this article constructs an optimized model and proposes a solving algorithm based on single target genetic by analyzing influence factors layout. The result numerical experiment shows that proposed method could fulfill requirements safety efficiency optimize cost while taking complex line situation, tracking operation, bidirectional into account.
