Embodiment：

With reference to the accompanying drawings and examples to inventing further describe in detail：

Fig. 1 is the self-positioning seismic detector communication scheme of untethered, and seismic detector independently sets up wireless network using itself WIFI module（Circle represents the coverage of seismic detector network in figure）, when multiple seismic detectors are in network coverage each other, multiple seismic detectors share a network（Region A, region C in figure）；When single seismic detector seismic detector adjacent thereto is not in network coverage each other, the seismic detector is certainly into network（Region B in figure）.By the use of Portable tablet personal computer or smart mobile phone as terminal device, when terminal device is in seismic detector network coverage, terminal device is automatically added to seismic detector network, is communicated with seismic detector in network（Terminal device A in figure）；When terminal device is not in seismic detector network coverage, terminal device can not be communicated with seismic detector（Terminal device B in figure）.

Fig. 2 is the self-positioning seismic detector automatic searching method flow chart of untethered, is comprised the following steps：

1st, network state is checked.

If the 2, being not connected with seismic detector network, point out user " not connected seismic detector network ", continue to connect seismic detector network, return to step 1；If having connected seismic detector network, step 3 is continued executing with.

3rd, wireless signal strength is updated：The wireless signal strength of current seismic instrument network is obtained, user is showed using the form of icon.

4th, seismic detector in search network：" search seismic detector " order is broadcasted into seismic detector network.

5th, the seismic detector list searched is obtained：Seismographic name information, which will be fed back, and arranged turns into list.

6th, the seismic detector list currently managed is contrasted：The seismic detector list got and the seismic detector list that currently manages are contrasted.

If the 7, list is unchanged, return to step 1；If list is changed, step 8 is continued executing with.

8th, set up and move into seismic detector list：Increased seismic detector information in relatively current managing listings in the seismic detector list searched is arranged, sets up and moves into seismic detector list.

9th, text prompt moves into seismic detector title and moves into the time.
