In step 354, in response to receiving described startup command pulse, described Vib. control system 90 can be enabled in the scan cycle in Vib. 95 sweep time in the startup of hope, and disconnected pulse while producing in starting scan cycle.Described Vib. control system 90 can by time disconnected pulse send to Vib. timing system 80.In step 355, Vib. timing system 80 can send to received time disconnected pulse the timing controller 230 of Vib. timing system 80.Described timing controller 230 can use the first time block 210 of Vib. timing system 80 so that the real time of being interrupted with reference to its real-time clock Measuring Time.The real time that the timing of above-mentioned measurement can be interrupted sends to the contact interface 240 of Vib. timing system 80, and the real time that be interrupted the timing of measurement again at contact interface 240 sends to vibrator system controller 70.In one embodiment, timing controller 230 can use the second time block 220 to measure and real time of acknowledging time interruption with reference to its real-time clock.The real time of the described second time break of measuring can be sent to contact interface 240, and contact interface 240 sends to vibrator system controller 70 by the real time of the time break of the second measurement again.
In step 356, vibrator system controller 70 can be determined the success of the real time scanning timing of the time break of depending on the measured sweep start time, and described data are sent to register origin system controller 20.In step 357, vibrator system controller 70 can be collected the data and the status information that are sent in scan period by Vib. 95 and Vib. control system 90.By reference to the data collected with analysis, vibrator system controller 70 can further be determined the success of scanning.Vibrator system controller 70 can send to register origin system controller 20 by described data and analysis.
In step 360, gather centring system 10 or register origin system controller 20 and can use received data, state and analysis to determine the success gathering.In one embodiment, due to received data, state and analysis, collection can be ended or be abandoned.
So, the embodiment of various technology described here makes each vibrator units synchronously to start each scan cycle at correct time and with the signal of acquisition system record and the reference scan that produced by register Vib. control system.Although described various technology with reference to the collection centring system 10 of determining startup sweep time of wishing, it should be understood that, in certain embodiments, can determine the startup sweep time of wishing by other parts in the seismic acquisition configuration 100 of for example vibrator system controller 70, register origin system controller 20 and register Vib. control system 40.For example, substitute the collection centring system 10 for determining startup sweep time of wishing, vibrator system controller 70 can determine the startup sweep time of hope and the described time is sent to register origin system controller 20, register origin system controller 20 then with gather that centring system 10 is associated to determine that whether this time suitable.
Although theme is described as specific to architectural feature and/or procedure on language, it should be understood that at theme defined in the appended claims and must not be limited to above-mentioned specific features or process.On the contrary, above-mentioned specific features and process are as just the exemplary form of implementing this claim.
