The drill bit 210 is deployed at the distal end of the drill pipe assembly 100 toward the subsurface formation. The communication drill rod assembly of this embodiment is deployed at the proximal end of the intelligent probe 220 facing above the formation. Then the drill pipe apparatus 100 transmits a rotational moment to the drill bit 210 along the communication drill pipe assembly and the intelligent probe 220 when the rotational moment is applied to the portion protruding from the earth's surface, so as to achieve drilling; during the drilling of the drill bit 210, the intelligent probe 220 with the sensor deployed therein will follow the drill bit 210 to the deep void 200100.
Fig. 2 shows that the communication drill rod assembly of the present embodiment includes a plurality of vertically adjacent combined relay rod segments 240 and communication rods 230. The two ends of the communication rod 230 and the relay rod section 240 of this embodiment are configured with rod joints. The lever joint is used for realizing torque transmission and electric signal transmission between the relay lever section 240 and the communication lever 230, between the relay lever section 240 and between the communication lever 230 and the communication lever 230. The communication rod 230 is internally provided with a through conductive cable, the conductive cable can realize electric signal transmission between rod joints at two ends of the communication rod 230, and the communication rod 230 closest to the ground surface is led out of a connecting wire through an appearance end and is connected with the ground control terminal 300.
For example, the guard bar in this embodiment is proximally adjacent to the communication bar 230. A relay pole segment 240 is connected between the plurality of communication poles 230 and the combination of the communication poles 230. The plurality of relay pole segments 240 may enable the handling of probe data, either alone or in combination.
And, the relay bar section 240 is internally constructed with a relay module. And the two ends of the relay module are respectively connected with the joints of the two ends of the rod through the conductive cable to realize electric signal transmission. The relay module itself may implement processing of the received and/or transmitted electrical signals, such as modulating, demodulating, enhancing, compensating, comparing, etc., the electrical signals, providing a basis for signal transmission, business applications, etc., of the ground control terminal 300 and the remote control terminal.
In addition, the main control circuit board of the embodiment receives data from the sensor combination. The data of the sensor combination includes data information of a plurality of different sensor types. The main control circuit board of the embodiment generates a check code of the data information of each sensor type based on hash check. The main control circuit board modulates the data information and the check code into detection data, and transmits the modulated detection data to the upper part of the stratum through a communication rod 230 adjacent to the intelligent probe rod 220.
Based on this, the relay pole section 240 of the data acquisition device of the present embodiment adjusts its own data capacity for the probe data according to the drilling depth and the communication state of the ground control terminal 300.
Fig. 3 is a schematic flow chart of the relay node 240 according to the present embodiment for adjusting its own data capacity. Fig. 3 shows that the relay pole segment 240 adjusts its own data capacity including the following steps.
S10 relay pole segment 240 receives probe data from a plurality of acquisition cycles. The probe data includes sensor data of various sensor types and a check code calculated based on hash of the sensor type data.
In the embodiment of step S10, the relay node 240 keeps the received probe data from interception, that is, the probe module sends the probe data to the ground control terminal 300 according to the communication link provided by the communication drill pipe, and the ground control terminal 300 receives the probe data without obstruction. The relay module is coupled to the communication link and receives probe data transmitted in the communication link.
The S20 relay pole segment 240 is provided with a first storage queue that sequentially stores probe data for a plurality of acquisition cycles with reference to a time sequence.
In the technical solution of step S20, the first storage queue is progressively arranged in the first storage queue according to the periodic sequence of the probe data of each sampling period.
The S30 relay rod section 240 acquires the drilling depth of the drill bit 210 and increases the storage capacity of the first storage queue in real time following the drilling depth of the drill bit 210.
In the embodiment, in the technical solution of step S30, the relay node 240 increases the storage capacity of the first storage queue, and sequentially increases the amount of storable probe data in the rear of the first storage queue. Then the storage capacity of the first storage queue of the plurality of relay pole segments 240 increases from top to bottom.
S40 the ground control terminal 300 receives and verifies the probe data.
In the technical solution of step S14, the ground control terminal 300 determines whether the detected data is damaged during the transmission process by calculating the comparison between the new check code of the sensor data and the transmission check code.
And S50, when the ground control terminal 300 fails to check any detection data, the ground control terminal sequentially requests each relay rod section 240 to resend the corresponding detection data stored by the ground control terminal according to the length direction of the communication drill rod from top to bottom.
And S60, when the relay pole section 240 receives the detection data in real time in the first storage queue, updating a plurality of detection data in the first storage queue according to a plurality of rules.
For example, the trunk node 240 actively transmits at least one probe data arranged in front of the first storage queue to the ground control terminal 300 according to an alternating period, and the trunk node 240 erases the probe data in real time after confirming that the probe data is reached in communication with the ground control terminal 300. Wherein the alternating period is at least guaranteed to be larger than the acquisition period.
For another example, after the relay node 240 retransmits the probe data according to the request of the ground control terminal 300, the probe data is erased.
Alternatively, the relay rod segment 240 is configured with an alternate curve against the drilling depth. This alternate curve appears to increase exponentially with drilling depth. Relay section 240 erases the probe data arranged in the first memory queue in real time according to the drilling depth and the contrast of the alternating curves.
