Wherein, the numerically-controlled machine tool control centre is configured as：
Receive the first control information transmission resources request message sent by mobile control terminal；
In response to receiving the first control information transmission resources request message, sends control information transmission resources response and disappear
Breath；
In response to the system message request message that control information transmission resources request message includes, broadcast system message；
If being not received by the retransmission request that the mobile control terminal is sent in the given time, judge whether to need more
New system message；
If it is determined that needing to update system message, then update system message is broadcasted；
Start the third timer in the numerically-controlled machine tool control centre；
Judge the update response message that the mobile control terminal is sent whether is received before the third timer expired；
And
If it is determined that being not received by the update response that the mobile control terminal is sent before the third timer expired
Message, then broadcast updates system message again.
10. the Remote Control System for CNC Machine Tool of flexibility enhancing as claimed in claim 9, it is characterised in that：Wherein, described
System message includes at least：Numerically-controlled machine tool type, the limitation of numerically-controlled machine tool arrange parameter and the timing of numerically-controlled machine tool control centre
Information.
