Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
See Fig. 1, a kind of wired seismic detector arrangement architecture convenient for investigating automatically includes seismic detector host 11, multiple adopts
Collecting unit 12, multiple data transmission cables 13 and multiple geophones 14, multiple collecting units 12 are assigned in multistage acquisition circuit,
In every grade of acquisition circuit, connected between adjacent two collecting units 12 by data transmission cable 13, each data transmission cable 13 is equal
On be connected with several geophones 14, each collecting unit 12 is responsible for the number of several geophones 14 of the right and left
Change, the connection in sequential series of collecting unit 12 that multistage acquisition circuit is located at middle part sends the data to seismic detector host 11.
Wherein, there are command channel, data channel and analog channel on data transmission cable 13, command channel is used for transmission seismic detector
The control command that host 11 is issued to each collecting unit 12, data channel are adopted for collecting unit 12 to the transmission of seismic detector host 11
The data of collection, analog channel are used to connect collecting unit 12 and the geophone 14 on its both sides.
See Fig. 2, the detection of link light 21, self-test indicator light 22, each seismic channel is respectively provided on multiple collecting units 12
Device status indicator lamp 23 and Seismic Detector button 24.
The investigation method of wired seismic detector arrangement architecture includes link check process, collecting unit process of self-test and inspection
Wave device state verification process；
See Fig. 3, link check process has specifically included following steps：Collecting unit 12 each first starts waiting for after the power-up
The link check command that seismic detector host 11 is sent, after receiving this order, 21 bright green of link light represents this collecting unit
12 link connections are normal, and then conversion link inspection order acquires the collecting unit 12 of circuit to subordinate, if more than certain time
The collecting unit 12 of subordinate's acquisition circuit does not receive link check command, then the link of subordinate's acquisition each collecting unit 12 of circuit refers to
Show that 21 shiny red of lamp represents that this acquisition circuit is abnormal；
Seismic detector host 11 since powering on timing downlink inspection order to each collecting unit 12, transmission link inspection
The interval of order can change, to avoid the command channel of the system of occupancy；When seismic detector host 11 just powers on, acquiescence use compared with
During normal work, order interval is lengthened for short interval transmission link inspection order；Movable part is needed to arrange in construction
When, then the interval of transmission link inspection order is reduced, to determine whether new connection is normal faster；Laying arrangement or movement
During arrangement, make collecting unit after the power is turned on when connecting seismic cable, due to seismic detector host 11 link check command interval compared with
Short, each collecting unit 12 receives link check command in a short period of time, then judges connection immediately by link light 21
Situation；The execution interval of additional command in link check command, so that collecting unit determines time-out time, collecting unit 12 is used for
Judge that the time-out time for not receiving link command is more than the interval time of seismic detector host transmission link inspection order.
See Fig. 4, collecting unit process of self-test has specifically included following steps：Each collecting unit 12 carries out unit after the power-up
Self-test acquires self-inspection data, then calculates test result, if 12 self-test of collecting unit is qualified, 22 bright green of self-test indicator light,
Otherwise shiny red.
See Fig. 5, wave detector state verification process：When the data transmission cable 13 and geophone 14 of 12 both sides of collecting unit connect
After connecing, the Seismic Detector button 23 of each collecting unit 12 is pressed, each collecting unit 12 starts to check geophone shape
State（Voltage value）If the state parameter of geophone 14 is qualified, corresponding wave detector status indicator lamp 24 is lighted, if some
Geophone 14 is abnormal, then is retested after replacing new geophone；
Under normal circumstances, the impedance of each geophone 14 is fixed, in certain numberical range, is examined at this time
24 bright green of wave device status indicator lamp, when the impedance value of certain road data transmission cable 13 detected is excessive, Ji Ci roads data transmission cable 13
Tap on unearthed shake wave detector 14 or the inside of geophone 14 break, corresponding wave detector status indicator lamp 24 is not at this time
It is bright；When the impedance value of certain road data transmission cable 13 detected is too small, i.e. line short, corresponding wave detector status indicator lamp at this time
24 shiny reds.
