A little steps are not that the inevitable sequence according to arrow instruction successively executes.Unless expressly state otherwise herein, these steps
It executes there is no the limitation of stringent sequence, these steps can execute in other order.Moreover, at least part in Fig. 2
Step may include that perhaps these sub-steps of multiple stages or stage are executed in synchronization to multiple sub-steps
It completes, but can execute at different times, the execution sequence in these sub-steps or stage, which is also not necessarily, successively to be carried out,
But it can be executed in turn or alternately at least part of the sub-step or stage of other steps or other steps.
It should be noted that three kinds of judgment modes can be combined judgement in the application, i.e. generalized time phase simultaneously
When Guan Xing, extreme value correlation and frequency domain correlation, only three meet simultaneously, public power distribution room and resident can be just assert within doors
Vibration source have relevance.Citing is illustrated below, referring to Fig. 4, Fig. 4 is the vibration source detection side of the embodiment of the present application
