Method the most according to claim 9, it is characterised in that described first collocation channel of described judgement and described Whether the state of two collocation channels meets default bar with the state of described first kind switches set and described second switch group Part, including:
Extract the state of described first collocation channel and described second collocation channel and described first kind switches set respectively State with described second switch group;
Judge the state of described first collocation channel and described second collocation channel and described first kind switches set respectively State with described second switch group;
Inquire about described pre-conditioned, mate described first collocation channel and the state of described second collocation channel and institute State first kind switches set and the state of described second switch group, it may be judged whether with the shape of described pre-conditioned middle typing State is identical.
