In certain embodiments, the unit 208 of standing is utilized as the conventional rechargeable battery that each unit provides about 70～80 hours mission lives.Because specific deployments may continue more than 15 days, so " uncontrolled " at sensor station 208 work may influence the efficient or the validity of seismic survey campaign.For example, the duty at active management sensor station 208 aspect is not the inefficient power consumption at sensor station 208.That is, unnecessarily high-power as requested duty running sensor station 208 meetings exhaust battery in about seven days.For example, the state that uncontrolled work can be included in all on-board circuitry and assembly is in " ready " situation is running sensor station 208 down continuously.This can cause sensor station 208 to continue 10 hours or continuous consuming cells of more time.The labour that battery is charged again is bigger, and can postpone or interfering data acquisition operations otherwise.It is bigger to change the same labour of battery, needs in addition to store to replace battery, and this is arm and a leg equally.In addition, the stand stored on-board finite capacity of unit 208.Can cause sensor station 208 to write down the data that do not contain information together in company with useful geological data according to the writing task state sensor station 208 of constantly turning round, this can cause on-board memory devices to reach capacity too early.In addition, when fetching the data that are kept in the memory device, meeting is elapsed time unnecessarily, and bandwidth and resource are because must fetch the data that do not contain information together with geological data.
The present invention includes one or more aspects of optimizing earthquake data acquisition, for example, the power consumption of above-mentioned system for acquiring seismic data, data storage capacity, optimize the use of earthquake equipment, the working state administration method and system of the mission life of increase earthquake equipment etc. to transmission bandwidth.The mode of operation management can be applicable to any earthquake equipment, comprises sensor, sensor station, receiver, transmitter, power supply, control module, focus, navigational tool, transponder or the like.
A kind of working state administration method of illustration is by making central station computer (CSC) 500, and the interactive one or more aspects between one or more mobile unit 502i and the seismic arrangement 210 realize robotization, optimize power consumption.In one embodiment, CSC 500 transmits the data that make one or more sensors station 208 of arranging in 210 can adjust duty according to the mode consistent with the ignition of seismic energy source 206i.Described data can be passed to specific sensor station or one group of sensor station, perhaps are passed to according to " broadcasting " mode and arrange 210.The data that response transmits, the circuit at sensor station 208 makes sensor 320 and miscellaneous equipment enter suitable duty, and every kind of duty has corresponding power usage: for example, sleep pattern, middle power state, high activity pattern etc.For example, sensor station 208 can utilize computer-readable medium, and described computer-readable medium can be visited by processor, so that carry out the instruction in the computer program that is included on the embeddeding computer computer-readable recording medium.Computer program can comprise one group of instruction of the signal that the controller in the geographic area that reception is concerned about by being arranged in transmits; Handle described signal, thereby determine one group of instruction of the duty relevant with the earthquake equipment that is configured to measure and write down geological data; One group of instruction with the transformation that starts to determined duty.Described medium can be relevant with one or more sensors station or any other earthquake equipment.In addition, CSC 500 can utilize computer-readable medium, and described computer-readable medium can be visited by processor, so that carry out the instruction in the computer program that is included on the embeddeding computer computer-readable recording medium.Described computer program comprises one group of instruction of the duty of determining to be arranged at least one earthquake equipment in the geographic area of being concerned about; One group of instruction with the coded data signal relevant with duty; The one group of instruction that transmits this signal with at least one earthquake equipment in the geographic area of being concerned about to being arranged in.
The CSC 500 of illustration comprises and using according to predefined procedure or progress, one or more processors of the instruction programming of the ignition of control seismic energy source 206i.For example, CSC 500 controls begin to ignite, the time interval between the order of ignition and the ignition.In a kind of pattern, a plurality of mobile unit 502i all navigate to independently seismic energy source 206i.When the seismic energy source 206i of location, each mobile unit 502i transmits signal to CSC 500.As previously mentioned, mobile unit 502i comprises the energy source controller 506i of the ignition of control seismic energy source 206i.In a kind of mode of operation of illustration, energy source controller 506i determines the position (for example, the x-y-z coordinate) of seismic energy source 206i according to GSP device (not shown), and coordinate is passed to CSC 500.In response, CSC 500 passes to energy source controller 502i to status information, and described status information can be visually or otherwise presented to operating personnel.Status information can comprise that report performs relative position and the scheduled time before beginning to ignite of the mobile unit 502i in the mobile unit formation of ignite preparing." report " is commonly referred to as the transmission coded data signal, and described coded data signal can be the signal that the voice signal that can be handled by CSC 500 or machine generate.When ready, CSC 500 transmits " arming " signal, and instruction mobile unit 502i prepares to ignite focus.When receiving " ignition " signal that CSC 500 transmits, mobile unit 502i starts the necessary operation of igniting seismic energy source 206i.Optionally, mobile unit 502i can only remain on " arming " position to seismic energy source 206i, thus when CSC 500 ready, thereby when transmitting " ignition " signal, energy source controller 504i ignites focus 206i immediately.
Exchanges data between mobile unit 502i and the CSC 500 makes CSC 500 can control report find the formation of the mobile unit 502i of seismic energy source 206i.According to programming instruction, CSC 500 determines the ignition order of seismic energy source 206i, and arranges the suitable instruction/data of 210 transmission to report mobile unit 502i and receiver.
In a kind of working state administration scheme, the sensor station 208 that constitutes arrangement 210 is divided into many groups sensor station of regulation.For convenience's sake, one group of sensor station 208 is commonly called a template.Each template is related with one or more seismic energy source 206i.Though each template can comprise different sensor stations 208, but situation needn't be like this.That is, some templates can share sensor station 208.Referring to Fig. 2, three illustrative templates 510a have been represented among the figure, 510b, 510c.Template 510a is made of different sensor stations 208 with 510b, and the more shared sensor stations 208 of template 510c and template 510a and 510b.In addition, a plurality of parts by the association of single template, single template and/or do not belong to one or more in the seismic station 208 of specific single template can form " supertemplete " 510d or composite shuttering.Template can be based on geometric configuration (for example, round, fan-shaped, square), predicts which sensor station 208 will detect the mathematical model from the seismic energy of specific seismic energy source 206i most effectively, relatively proximity or any other suitable method.Certainly, in actual applications, template can comprise dozens of or hundreds of sensor stations 208.In the simple arrangement of an illustration, all the sensors station 208 of arranging in 210 is grouped in the single template related with employed each seismic energy source 206i together.In the complicated arrangement of an illustration, for each seismic energy source 206i forms an independent template.The effectiveness of template is discussed below in conjunction with the deployment mode of illustration.
In the deployment mode of an illustration, make the duty at the sensor station in the seismic arrangement consistent with the state and the number of the seismic energy source that is ready to " ignition " or igniting.For example, when the minimized number seismic energy source report of presetting performed the ignition preparation, sensor unit was transformed into partially or completely activity pattern from sleep pattern, to detect and the record seismic energy.When the number that performs the seismic energy source of ignite preparing when report was lower than preset minimum, CSC signals to sensor unit made it be transformed into sleep pattern from activity pattern partially or completely.For convenience's sake, these two values will be called as " waking up " threshold value and " sleep " threshold value respectively.
Referring now to Fig. 5,, represented the control seismic arrangement among the figure, such as the process flow diagram 600 of arranging 210, wherein single template comprises all the sensors station in the arrangement, focus to be ignited always has 5.Threshold wake-up value is set as 3, and sleep threshold is set as 0.In the following discussion, for the ease of narration, omitted the Reference numeral of each assembly.
At first, in step 602, whole arrangement is in sleep pattern.In step 604, when first focus of location, first mobile unit transmits " Ready to Arm " message." Ready toArm " message represents that normally focus is in situation that will be detonated or the message that can enter this situation immediately.In step 606, CSC adds this mobile unit to tracking in " ready " tabulation (a kind of electronic list or formation) of the state of the mobile unit of CSC report.In step 608, CSC determines that the sensor station should keep sleep pattern, because have only a mobile unit report ready, and threshold wake-up value is 3.In step 610, CSC confirms that enough focus can be used for satisfying threshold wake-up value, and continues sleep pattern.Can be in independent tabulation, such as the remaining blast of counting in " shot management " tabulation, SCS can tabulate with reference to this.When second mobile unit when second focus sends " Ready to Arm " message, repeating step 604,606,608 and 610.In addition, CSC does not wake sensor arrangement up, because have only two mobile unit reports ready, and threshold wake-up value is 3.When the 3rd mobile unit when the 3rd focus sends " Ready to Arm " message, repeating step 604 and 606.CSC adds the 3rd mobile unit in " ready " tabulation to.But, in step 608, because that three mobile units have been reported is ready, and threshold wake-up value is 3, and therefore by transmitting the signal that the indication blast will beginning, CSC enters step 612.Respond this signal, the sensor station in the template (it is whole arrangement) is transformed into one of pattern of several power usage risings from sleep pattern, and described several modes will illustrate in greater detail with reference to figure 7 below.In step 614, first focus is detonated, and in step 616, CSC removes first mobile unit from " ready " tabulation 601.In step 618, CSC checks sleep threshold, and do not need to determine whole sleep, because have two mobile units in " ready " tabulation, greater than the sleep threshold that is 0.Repeating step 614 is ignited second focus, and in step 616, CSC removes second mobile unit from " ready " tabulation 601.In step 620, the 4th mobile unit sends " Ready to Arm " message from the 4th focus, and in step 622, CSC adds the 4th mobile unit in " ready " tabulation to.Afterwards, be detonated in step 614 and 616, the three focus, CSC removes the 3rd mobile unit from " ready " tabulation.In step 618, CSC checks sleep threshold, and do not need to determine whole sleep, because have a mobile unit in " ready " tabulation, greater than the sleep threshold that is 0.To the 4th focus repeating step 614 and 616.In step 618, CSC checks sleep threshold, and determines to require sleep pattern, equates with the number of mobile unit in " ready " tabulation because be 0 sleep threshold.CSC transmits the signal that the indication blast will stop.In response, in step 602, the sensor station is transformed into sleep pattern.In step 604 and 606, after the 5th focus sends " Ready to Arm " message, the 5th focus is added in " ready " list cell.In step 608, CSC at first determines not need to wake up, because have only a mobile unit report ready.But, in step 610, CSC determines to have only a focus to wait until to be detonated.Thereby CSC enters step 612, makes whole arrangement be transformed into complete active power mode.At last, be detonated in step 614 and 616, the five focus, CSC removes the 5th mobile unit from " ready " tabulation.In step 618, CSC finds that the number of the mobile unit that preparation is ignited is 0, equals the number of the residue blast in sleep threshold and " shot management " tabulation.Thereby CSC transmits the signal that the indication blast will stop.In response, the sensor station is transformed into sleep pattern.
In another kind of illustrative deployment mode, to arrange and be grouped into a plurality of templates, each template is related with independent focus.In the example below, have 8 ignition, threshold wake-up value is set as 4, and sleep threshold is set as 2.
Referring now to Fig. 6,, represented process flow diagram 700 among the figure, wherein at first in step 702, whole arrangement is in dormancy duty or sleep pattern.In step 704, when receiving " Ready to Arm " message from first mobile unit of locating first focus, in step 706, CSC adds this mobile unit in " ready " tabulation to.In step 708, CSC determines not need the change of duty " to wake up " in other words, because have only a mobile unit report ready, and threshold wake-up value is 4.In step 710, CSC determines that existence can be used for satisfying enough mobile units of threshold wake-up value, and continues sleep pattern.When the second and the 3rd mobile unit respectively when the second and the 3rd focus sends " Ready to Arm " message, repeating step 704-710.To send the 4th mobile unit repeating step 704-706 of " Ready to Arm " message from the 4th focus.But, in step 708, because that four mobile units have been reported is ready, and threshold wake-up value is 4, so CSC determines that in the template which is corresponding with first～the 4th focus, and forms compound or " super " template.Thereby CSC enters step 712, and in step 712, CSC transmits and indicates the sensor station that belongs to supertemplete should be transformed into complete activity pattern, with the signal of record geological data.Respond this signal, the sensor station in the supertemplete is transformed into active power mode from sleep pattern.When the sensor station in the supertemplete had been powered, in step 714, first focus was detonated, and in step 716, CSC removes first mobile unit from " ready " tabulation.In step 718, CSC checks sleep threshold, do not need to determine whole sleep, because have three mobile units in " ready " tabulation, greater than the sleep threshold that is 2.In step 720, the 5th mobile unit sends " Ready to Arm " message from the 5th focus, and in step 722, CSC adds the 5th mobile unit in " ready " tabulation to.In response, in step 712, CSC transmits the signal that the sensor station of indicating the template that belongs to related with the 5th focus should be transformed into complete activity pattern.Afterwards, in step 714, second focus is detonated, and in step 716, CSC removes second mobile unit from " ready " tabulation.In step 718, CSC checks sleep threshold, do not need to determine whole sleep, because have three mobile units in " ready " tabulation, greater than the sleep threshold that is 2.To the 3rd focus repeating step 714-716.In step 718, when CSC checked sleep threshold, CSC determined to require sleep pattern, because be the number that 2 sleep threshold equals the mobile unit in " ready " tabulation.Step 724 confirm enough blasts wait until enter sleep pattern after, CSC transmits the signal that the indication blast will stop.In response, in step 702, all sensor stations are transformed into sleep pattern.When the 6th mobile unit when the 6th focus sends " Ready to Arm " message, repeating step 704-706.At step 708-710, CSC does not wake sensor arrangement up, because ready less than the report of four mobile units, and enough focus can be used for keeping sleep pattern.
To send the 7th mobile unit repeating step 704-76 of " Ready to Arm " message from the 7th focus.In step 708, because that four mobile units have been reported is ready, and threshold wake-up value is 4, so CSC determines that in the template which is corresponding with the 4th～the 7th focus, and forms compound or " super " template.Afterwards, in step 712, CSC transmits the signal of indicating the sensor station that belongs to supertemplete should be transformed into complete activity pattern.Respond this signal, the sensor station in the supertemplete is transformed into active power mode from sleep pattern.At step 714-716, the 4th focus is detonated, and is removed from " ready " tabulation.In step 718, CSC checks sleep threshold, do not need to determine whole sleep, because have three mobile units in " ready " tabulation, greater than the sleep threshold that is 2.At step 720-722, the 8th mobile unit sends " Ready to Arm " message from the 8th focus, and is added in " ready " tabulation.In step 712, CSC transmits the signal that the sensor station of indicating the template that belongs to related with the 8th focus should be transformed into complete activity pattern.At step 714-716, the 5th focus is detonated, and is removed from " ready " tabulation.In step 718, CSC checks sleep threshold, do not need to determine whole sleep, because have three mobile units in " ready " tabulation, greater than the sleep threshold that is 2.At step 714-716, the 6th focus is detonated, and is removed from " ready " tabulation.
In step 718, CSC at first determines to require sleep pattern, because have only two mobile unit reports ready.But, in step 724,, CSC is detonated, as shown in " shot management " tabulation owing to determining to have only two focus to wait until.Thereby CSC makes the sensor station keep complete active power mode.Afterwards, at step 714-716, the 7th and the 8th focus is detonated successively, and is removed from " ready " tabulation.In step 724, CSC finds that the mobile unit of preparing to ignite is 0, equals the number of the residue blast in sleep threshold and " shot management " tabulation.Thereby CSC transmits the signal that the indication blast will stop.In response, in step 702, all the sensors station that is in complete active power mode is transformed into sleep pattern.
Will be appreciated that the duty that many schemes or agreement can be used to control the ignition of seismic energy source 206i and change or adjust sensor station 208 rightly.As mentioned above, CSC 500 can be programmed, thereby only after formation comprises that the report of preset minimum performs the focus 206i that ignite to prepare, just begins the ignition of focus 206i, the order that the ignition order can be reported to CSC 500 based on focus 206i.The time interval between selecting to ignite is to guarantee that the sensor station has time enough and receives and write down geological data.In addition, tabulation or formation can be dynamic because when in the formation after preceding member is detonated, can be to this formation interpolation focus 206i.In addition, the agreement that the order of igniting focus 206i is set can comprise the multilayer complicacy.For example, forecast model can be used to optimize ignition order or order.Forecast model can rearrange the ignition order, to improve the quality of data, reduces running time or the like.For example, forecast model can use Geographic Information System (GIS) database, from the data of previous blast, well data, historical data etc.In addition, although above-described method utilizes human intervention to control the ignition of focus 206i, but in application more of the present invention, programmable controller can be unmanned for applying comprehensive order and control to specified activities with intervening.
In another kind of agreement, CSC 500 can use coded data to come the sensor station of Instruction Selection to be transformed into the duty of hope according to the order of formation.For example, perform the state of igniting the focus 206i for preparing according to report, CSC 500 can determine that the sensor station of discerning should be in running order in one or more templates, so that monitor and record data.Thereby CSC 500 can instruct the sensor station of discerning in these templates to be transformed into monitoring and writing task state.In a kind of transmission mode, instruction only is sent to the sensor station of the identification in these templates.In another kind of transmission mode, can be to arranging 210 broadcasting instructions, but comprise and make each sensor station can determine the whether further information in correlate template of this sensor station.The exemplary information that is used to make decision can be a position coordinates, sensor station identification numbers, time, duty etc.
In another kind of agreement, but the signal of CSC 500 travelling belt coded datas, described coded data comprises the instruction that is transformed into duty to some sensor station, and further comprises other data and/or the instruction that makes each sensor station can oneself select another duty.For example, perform the state of igniting the focus 206i for preparing according to report, CSC 500 can determine that the sensor station among the template 510d should be in the duty of beginning data recording.In this identical or different signal, CSC 500 can transmit to the sensor station among the template 510d and make each sensor station can determine whether the data of actual opening entry data.For example, CSC 500 can determine that several focus are ready in template 510d to ignite successively, and instructs the sensor station in this template to enter the writing task state of preparing.Identical signal or discrete signal can provide the information such as timing and/or source location information, described information makes each sensor station can determine whether opening entry, perhaps before entering recording status, wait for, till given source is ready to ignite always.That is, the sensor station among the template 510b can opening entry, because the focus that their contiguous selections will be ignited, but the sensor station among the template 510a can postpone to enter the record data state, because near inadequately with the focus of selecting to ignite.But, in case when preparing to ignite with the nearest one or more focus in these sensor stations, the sensor station among the template 510a can be quickly converted to recording status.Will be appreciated that this method can optimize the use of sensor station memory capacity.On the other hand, the selection that will be appreciated that suitable duty is finished with each sensor station is collaborative by CSC500.
Referring now to Fig. 2,, will be appreciated that any earthquake equipment in the seismic arrangement 210, can be programmed such as sensor station 208, thus " oneself is selected " duty in specific earthquake data acquisition activity.In Shuo Ming the method, CSC 500 regularly transmits data to seismic arrangement 210 in the above.In a kind of arrangement, these data are not specific to special sensor station, focus etc.Further, as previously mentioned,, perhaps broadcast this data to whole seismic arrangement to the part of seismic arrangement.Advantageously, each earthquake equipment is known its position with respect to reference point.Thereby by with reference point data being encoded, each earthquake equipment is independently selected the suitable response to broadcast singal.
For example, the GPS device makes the sensor station can know that it is with respect to specifying focus, the position of " flashpoint " in other words.Broadcast singal can comprise one or more focus, in other words the identity of flashpoint.When receiving broadcast singal, each sensor station determines whether to adjust its duty separately according to its position with respect to one or more focus.In addition, broadcast singal can comprise the selection parameter, and the sensor station can use described selection parameter to determine whether to need to change duty.For example, broadcast singal can define geometric configuration, and is for example fan-shaped, circle etc., and the sensor station must be positioned at wherein, can the sensing seismic energy and the duty of record geological data so that carry out, this requires complete active power state.Thereby, in one aspect, the invention provides automatically a kind of and intelligently the current consuming apparatus in the seismic arrangement be transformed into suitable duty, thereby optimize the method and apparatus of electricity usage.
Referring now to Fig. 7,, the various duties at particular sensor station and the exemplary diagram 800 of corresponding power rating thereof have been represented among the figure.According to the order of power usage, power rating comprises: closed condition 802, deep sleep 804, sleep state 806, radio receiver active state 808 and active state 810.In off position 802, power usage minimum (if any).By other hardware is switched on, every kind of follow-up work state increases the activity of power house.In deep sleep 804, the circuit that only wakes up is energized, signal or instruction that this allows the response of sensor station to transmit.At sleep state 806, radio receiver is energized, and processing hardware can be directed (booted on).In radio receiver active state 808, the sensor station can make transceiver and processor switch on fully.In active state 810, can make all on-board circuitry and hardware, comprise sensor, processor, RAM, GPS enter full ready state.Will be appreciated that this progress can be the incremental advance shown in arrow 812, or the great-jump-forward shown in arrow 814 advances.Thereby, will be appreciated that sensor station circuit can select duty for the sensor station of the duty that appropriately given seismic arrangement.In addition, this circuit can be as one sees fit effectively conversion between several duties are one of any, with the working condition that is fit to change.
