多个并发fsm Fysom

Question

我用python写了一段代码来做一些操作，这些操作必须是并发的，这就是为什么我把FSM画成两个并发的FSM的原因。在python中使用Fysom时，我想到了两个FSM的定义。但在某种程度上，我在想如何进行过渡；我在这里有点困惑，这就是为什么我请求您的支持。如果有人能帮忙，我将不胜感激。这是我定义fsms的方式，请告诉我这在Fysom中是否没有意义

fsm1 = fysom({
'initial':'Idle',
'events':[
    {'name':'sc','src':'Idle','dst':'percent30'},
    {'name':'sc','src':'percent30','dst':'percent60'},
    {'name':'sc','src':'percent60','dst':'percent90'},
    {'name':'sc','src':'percent90','dst':'Idle'}
    ],
'callbacks':{
    'onIdle':onIdle,
    'onRead':onpercent30,
    'onTurnon':onpercent60,
    'onDisplay':onpercent90
    }
    })  

      fsm2 = fysom({
    'initial':'SR',
    'events':[
        {'name':'Right','src':'SR','dst':'SL'},
        {'name':'Left','src':'SL','dst':'SR'}
        ],
    'callbacks':{
        'onIdle':onSR,
        'onRead':onSL
        }
})  

没有添加从fsm1到fsm2的转换，这是我感到困惑的部分，我想问一下，如果我想的是完全不可能的，我必须将两者合并在一起。

如果你使用线程，它就能工作。
