Abstract
With the prospect of new and different Maglev train lines to be constructed, the
interoperability properties of the Maglev train have become a new issue. The
safety performance requirement of the Maglev control equipments for
interoperability operation was derived based on the objectives of the crossing
boundary between different lines and the corresponding procedures have been
modelled with stochastic Petri nets. Firstly, the whole objectives of the crossing
boundary of different Maglev lines were defined taking the operation efficiency
and safety target into consideration. The train would cross the boundary without
decreasing the speed. The operation efficiency and the safety property of the
crossing procedure should be guaranteed. In addition, based on the
interoperability objectives, the interoperability operation procedure of the
Maglev train was specified and the Maglev control equipments used for the
interoperability were designed. The control equipments were used to transmit the
data between different control systems of different lines. Thirdly, the process of
the train passing the boundary of different lines was modelled with the stochastic
Petri nets based on the different operation stage of the train. Finally, by means of
the simulation of the model, the safety performance requirements of the Maglev
control systems were derived based on the defined crossing success rate.
