Description

Technical Field

[0001] This invention relates to the field of drilling rig technology, and specifically to a drilling rig data acquisition method and system based on remote control operation. Background Technology

[0002] In the fields of engineering geological exploration and tunnel construction, accurately obtaining drilling rig data is a core prerequisite for analyzing rock strata characteristics and optimizing construction plans. Current data acquisition methods mainly fall into two categories: manual recording and automated data acquisition systems. Manual recording relies on operators observing on-site and manually recording parameters (such as borehole depth and drilling speed), which suffers from low efficiency, poor real-time performance, and a high rate of subjective error, making it difficult to meet the demands of high-precision construction management.

[0003] Automated data acquisition systems can record drilling rig parameters in a timely and accurate manner, facilitating subsequent data processing. However, existing automated data acquisition systems have some technical shortcomings: (1) Insufficient coupling with the drilling rig control system. The existing system only passively receives sensor data and cannot identify the working status of the drilling rig (such as automatic drilling, manual debugging, idling standby, etc.), resulting in a large amount of invalid data (such as abnormal fluctuations during equipment start-up and shutdown, non-drilling working parameters) being mixed and stored, which significantly increases the difficulty of subsequent data processing. (2) Lack of human-computer interaction and data identification capabilities. Geological exploration requires marking borehole attributes (such as borehole number, dip angle, and rock stratum type). However, traditional systems cannot provide on-site interactive interfaces, making it difficult for operators to enter working condition information in a timely manner, resulting in data being out of the construction context and reducing the value of analysis. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drilling rig data acquisition method and system that can dynamically switch the data acquisition working state and the drilling rig working state through remote control operation, thereby coupling the data acquisition working state and the drilling rig working state to filter invalid data, improve data validity, and improve human-machine collaboration efficiency.

[0005] To address the aforementioned technical problems, the present invention provides a data acquisition method for drilling rigs based on remote control, comprising at least the following steps: The system receives user commands via a wireless remote control and transmits these commands to the drilling rig controller. The drilling rig controller determines the drilling rig's working status and dynamically switches the data acquisition working status based on the received user instructions. The drilling rig's working status includes automatic advance status, manual drilling status, and retraction status. The data acquisition working status includes at least standby status, automatic acquisition status, and forced acquisition status. If the data acquisition working state is in the standby state, the drilling rig controller acquires drilling rig data through sensors installed on the drilling rig; If the data acquisition working state is in the automatic acquisition state and the drilling rig working state is in the automatic propulsion state, then the drilling rig controller collects the drilling rig data through the sensors installed on the drilling rig, calculates the effective drilling depth based on the collected drilling rig data, packages the collected drilling rig data and the calculated effective drilling depth into a data package, and transmits the packaged data to the host computer. If the data acquisition working state is in the forced acquisition state and the drilling rig working state is in the manual drilling state or the retraction drilling state, the drilling rig controller collects the drilling rig data through the sensors installed on the drilling rig, packages the collected drilling rig data, and transmits the packaged data to the host computer.

[0006] In a preferred embodiment, the data acquisition working state further includes a data acquisition paused state; If the data acquisition working state is switched from the automatic acquisition state to the data acquisition paused state, the drilling rig controller continuously acquires the drilling rig data through the sensors installed on the drilling rig, and the effective borehole depth data is not updated, remaining at the value in the previous automatic acquisition state, and the acquired drilling rig data and the effective borehole depth before the state switch are packaged together.

[0007] In a preferred embodiment, the drilling rig data includes propulsion stroke, propulsion speed, propulsion displacement, rotational torque, rotational speed, propulsion force, and pull-out force.

[0008] In a preferred embodiment, the calculation of the effective borehole depth based on the collected drilling rig data specifically includes the following steps: The current drill pipe advance speed and advance displacement are obtained through displacement sensors; Monitor the push limit position switch signal; if the push limit position switch signal is triggered, then round up and correct the current drill pipe push displacement. Calculate the overall effective drilling speed and overall effective drilling displacement based on the advance speed and displacement of each drill pipe; The effective drilling depth is obtained based on the initial value of the drilling depth and the effective advance displacement of the overall drill rod.

[0009] In a preferred embodiment, the monitoring of the thrust limit position switch signal, if triggered, involves rounding and correcting the current drill pipe thrust displacement, specifically including the following steps: The system detects and monitors the push-to-limit position switch signal. If the signal is continuously triggered for a preset time, it is determined that the drill pipe has completed drilling. Get the current standard drill pipe length L0 and the current drill pipe advance displacement L1; Calculate the displacement error based on the current standard drill pipe length L0 and the current drill pipe advance displacement L1. The specific calculation method is as follows: , If the displacement error If the current drill pipe advance displacement L1 is less than the predetermined threshold, the current drill pipe standard length L0 is corrected; otherwise, the effective drilling depth calculation is paused and an alarm is sent.

[0010] In a preferred embodiment, if the data acquisition working state is in the automatic acquisition state or the forced acquisition state, the drilling rig controller sets the acquisition parameters based on the user instructions transmitted by the wireless remote controller, and binds and stores the acquisition parameters as data attribute identifiers with the acquired data.

[0011] In a preferred embodiment, the collected parameters include at least the tunnel length, borehole number, borehole inclination angle, and drill bit type.

[0012] The present invention also provides a system for acquiring drilling rig data using any of the above-described remote control operation-based methods, comprising at least: Sensors, which are mounted on the drilling rig for collecting drilling rig data; A wireless remote controller, which is used to receive user commands and transmit the user commands to the drilling rig controller; The drilling rig controller is used to determine the working status of the drilling rig and dynamically switch the data acquisition working status based on the received user instructions, collect drilling rig data through the sensors, and calculate the effective drilling depth based on the drilling rig data. The host computer is used to store the packaged data.

[0013] In a preferred embodiment, the sensors include a system pressure sensor, a return oil pressure sensor, a propulsion displacement sensor, a rotational pressure sensor, a rotational speed sensor, a propulsion pressure sensor, and a propulsion limit position switch; The system pressure sensor is installed at the oil inlet of the drilling rig valve assembly to collect the real-time working pressure of the drilling rig hydraulic system; The return oil pressure sensor is installed on the return oil pipeline of the drilling rig valve group to collect the return oil pressure of the drilling rig hydraulic oil. The thrust displacement sensor is installed on the piston rod of the thrust cylinder of the drilling rig valve group or in the oil circuit of the thrust motor, and is used to collect the thrust speed and thrust displacement of each drill rod. The rotary pressure sensor is installed in the rotary motor oil inlet pipe of the drilling rig valve group to collect the rotary hydraulic pressure of the drilling rig. The rotational speed sensor is installed on the output shaft of the drilling rig's rotary motor and is used to collect the rotational speed of the drill rod. The propulsion pressure sensor is installed in the rodless chamber pipeline of the propulsion cylinder of the drilling rig valve group and is used to collect the pressure in the propulsion direction of the drilling rig. The thrust limit position switch is installed at the end of the drill frame guide rail of the drilling rig and is used to collect position trigger signals to determine the thrust stroke.

[0014] In a preferred embodiment, the wireless remote control is equipped with a status indicator light; The data acquisition working state is in the automatic acquisition state, and the status indicator light corresponds to the slow flashing state; The data acquisition working state is in the forced acquisition state, and the status indicator light corresponds to the fast flashing state; The data acquisition operation is in the standby state, and the status indicator light is in the constantly lit state.

[0015] The remote-controlled drilling rig data acquisition method and system of the present invention have the following advantages compared with the prior art: (1) The drilling rig data acquisition method based on remote control operation of the present invention receives user instructions through a wireless remote controller and transmits the user instructions to the drilling rig controller, realizing remote interaction between the operator and the drilling rig system. This design solves the problem of "lack of human-machine interaction interface" in traditional systems. The operator can input working condition information (such as borehole number, rock stratum type, etc.) in real time, binding the data with the construction context and improving the analytical value of the data. At the same time, remote control operation avoids the inefficiency and subjective error of manual on-site recording, improves the real-time performance and accuracy of data acquisition, and improves the efficiency of human-machine collaboration.

[0016] Based on received user commands, the drilling rig controller determines the drilling rig's operating status and dynamically switches between data acquisition states. The drilling rig's operating states include automatic advance, manual drilling, and retraction. Data acquisition states include at least standby, automatic acquisition, and forced acquisition. The drilling rig controller actively identifies the drilling rig's operating status (automatic advance, manual drilling, retraction) through user commands and dynamically switches the data acquisition state (standby, automatic acquisition, forced acquisition). Through a dual-state coupling mechanism, it solves the problem of insufficient coupling in existing systems. When the drilling rig is in automatic advance mode and the data acquisition mode is in automatic acquisition mode, the system calculates the effective drilling depth, filtering abnormal fluctuations in data during equipment start-up and shutdown, reducing invalid data storage, improving data validity, and reducing the difficulty of subsequent data processing. Simultaneously, in automatic acquisition mode, the system calculates the effective drilling depth in real time based on sensor data, replacing manual estimation or post-processing. This avoids depth calculation errors caused by equipment vibration and parameter fluctuations during start-up and shutdown, improving the accuracy of key construction parameters and providing a reliable basis for rock strata characteristic analysis (such as fault location and lithological changes).

[0017] In non-automatic operation, the drilling rig is in manual drilling or retracting mode, and the data acquisition mode is in forced acquisition mode, providing a complete operating condition background for later analysis and avoiding data bias.

[0018] (2) The drilling rig data acquisition method based on remote control operation of the present invention operates in either automatic or forced acquisition mode. The drilling rig controller sets acquisition parameters based on user instructions transmitted by the wireless remote controller. By receiving user instructions and setting acquisition parameters in real time through the wireless remote controller, remote interaction between the operator and the drilling rig system is realized. This solves the problem in traditional systems where the lack of a field interaction interface makes it difficult for operators to simultaneously input working condition information (such as borehole attributes) during data acquisition, resulting in data being out of context. Operators directly input parameters (such as tunnel length, borehole number, etc.) during the acquisition phase, combining manual experience with system data, avoiding delays and errors caused by post-entry data entry, and improving the real-time performance and completeness of the data.

[0019] The drilling rig controller binds and stores the acquired parameters as data attribute identifiers, addressing the problem of traditional data acquisition systems that only store sensor values ​​and lack correlation with the construction scenario (e.g., the rock strata type or drill bit status corresponding to a certain set of borehole data is unknown). This leads to the need for additional manual context matching during later analysis, resulting in low efficiency and a high risk of errors. By binding and storing acquired parameters (such as borehole number and dip angle) as data tags, a deep correlation between data and the construction scenario is achieved. This binding mechanism improves the interpretability and analytical value of the data, providing structured data support for rock strata characteristic prediction and construction scheme optimization.

[0020] The collected parameters include at least tunnel length, borehole number, borehole inclination angle, and drill bit type. Tunnel length determines the absolute location of the borehole within the tunnel, aiding spatial data analysis; borehole inclination angle distinguishes between vertical and inclined borehole data, avoiding deviations in rock layer thickness calculations due to inclination angle errors; drill bit type indicates drill bit wear status or suitability for specific rock layer types, explaining abnormal fluctuations in parameters such as propulsion speed and torque (e.g., sudden data changes after drill bit replacement). Standardized collection and binding of these parameters allows for refined filtering and analysis based on specific scenarios (e.g., "a certain section + a certain inclination angle + a certain drill bit type") in subsequent data processing, significantly reducing the complexity of data cleaning and correlation.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an integral connection, or a detachable connection; they can refer to the internal connection of two components; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example 1 This embodiment of a drilling rig data acquisition method based on remote control operation includes at least the following steps: Step S1 involves receiving user commands via a wireless remote control and transmitting them to the drilling rig controller. This design enables remote interaction between the operator and the drilling rig system. This design addresses the lack of a human-machine interface in traditional systems, allowing operators to input operational information (such as borehole number and rock strata type) in real time, binding data to the construction context and enhancing its analytical value. Simultaneously, remote control operation avoids the inefficiency and subjective errors of manual on-site recording, improving the real-time nature and accuracy of data acquisition and enhancing human-machine collaboration efficiency.

[0026] In step S2, the drilling rig controller, based on received user commands, determines the drilling rig's operating status and dynamically switches the data acquisition status. The drilling rig's operating status includes automatic advance, manual drilling, and retraction. The data acquisition status includes at least standby, automatic acquisition, and forced acquisition. The drilling rig controller actively identifies the drilling rig's operating status (automatic advance, manual drilling, retraction) through user commands and dynamically switches the data acquisition status (standby, automatic acquisition, forced acquisition). This dual-state coupling mechanism solves the problem of insufficient coupling in existing systems.

[0027] If the data acquisition is in standby mode, the drilling rig controller collects drilling rig data through sensors installed on the drilling rig.

[0028] If the data acquisition mode is in automatic acquisition mode and the drilling rig is in automatic advance mode, the drilling rig controller collects drilling rig data through sensors installed on the rig, calculates the effective drilling depth based on the collected data, and packages the collected data and calculated effective drilling depth into a single data packet before transmitting it to the host computer. In automatic advance mode, the system filters out abnormal fluctuations in data during equipment start-up and shutdown, reduces invalid data storage, improves data validity, and reduces the difficulty of subsequent data processing. In automatic acquisition mode, the system calculates the effective drilling depth in real time based on sensor data, replacing manual estimation or post-processing. This avoids depth calculation errors caused by equipment vibration and parameter fluctuations during start-up and shutdown, improving the accuracy of key construction parameters and providing a reliable basis for rock strata characteristic analysis (such as fault location and lithological changes).

[0029] If the data acquisition mode is in forced acquisition mode and the drilling rig is in manual drilling or retraction mode, the drilling rig controller collects drilling data through sensors installed on the drilling rig, packages the collected data, and transmits the packaged data to the host computer. In non-automatic operation, when the drilling rig is in manual drilling or retraction mode and the data acquisition mode is in forced acquisition mode, a complete operational context is provided for subsequent analysis, avoiding data bias.

[0030] The data acquisition working status also includes a data acquisition paused state. If the data acquisition working status switches from automatic acquisition to data acquisition paused state, the drilling rig controller continuously acquires drilling rig data through sensors installed on the drilling rig, and the effective drilling depth data is not updated, remaining at the value from the automatic acquisition state. The acquired drilling rig data and the effective drilling depth before the state switch are packaged together. This design avoids the loss of critical data (such as the last segment of effective drilling data before the pause) when the drilling rig enters a paused state due to a temporary interruption (such as waiting for instructions or equipment adjustments). It also avoids the problem in traditional data acquisition where the inability to identify the drilling rig's working status leads to the recording of abnormal data during equipment start-up / shutdown phases or non-drilling conditions, requiring manual filtering of valid data later. Continuous data acquisition and packaging during the paused state ensures the integrity of the data chain before and after the interruption. Simultaneously, the acquired data can be used to monitor equipment status (such as whether the drill bit is stuck or whether the hydraulic system pressure is abnormal), promptly detecting and handling faults, and preventing data anomalies due to equipment problems after restarting.

[0031] If the data acquisition is in automatic or forced acquisition mode, the drilling rig controller sets the acquisition parameters based on user instructions transmitted by the wireless remote controller, and stores these parameters as data attribute identifiers bound to the acquired data. By receiving user instructions and setting acquisition parameters in real time via the wireless remote controller, remote interaction between the operator and the drilling rig system is achieved. This solves the problem of traditional systems lacking a field interaction interface, making it difficult for operators to simultaneously input working condition information (such as borehole attributes) during data acquisition, resulting in data being out of context. Operators directly input parameters (such as tunnel length, borehole number, etc.) during the acquisition phase, combining manual experience with system data, avoiding delays and errors from post-entry data entry, and improving the real-time performance and completeness of the data.

[0032] In this embodiment, as Figure 3 As shown, the collected parameters include at least tunnel length, borehole number, borehole inclination angle, and drill bit type. Tunnel length determines the absolute position of the borehole within the tunnel, aiding spatial data analysis; borehole inclination angle distinguishes between vertical and inclined borehole data, avoiding deviations in rock layer thickness calculations due to inclination angle errors; drill bit type indicates drill bit wear status or suitability for rock layer types, explaining abnormal fluctuations in parameters such as propulsion speed and torque (e.g., sudden data changes after drill bit replacement). Standardized collection and binding of these parameters allows for refined filtering and analysis based on specific scenarios (e.g., "a certain section + a certain inclination angle + a certain drill bit type") in subsequent data processing, significantly reducing the complexity of data cleaning and correlation.

[0033] like Figure 1 As shown, after the drilling rig controller is started, it enters standby mode by default. The drilling rig controller collects drilling rig data through sensors installed on the drilling rig, but does not store the drilling rig data. It is used to monitor the drilling rig initialization status and filter invalid data during idling and standby.

[0034] Core operating conditions, such as Figure 2 As shown, the wireless controller receives user commands and sends them to the drilling rig controller. The drilling rig controller determines the drilling rig's operating status as automatic propulsion mode and switches the data acquisition mode to automatic acquisition mode based on the user commands. Based on the user commands, the drilling rig controller sets acquisition parameters, including tunnel length, borehole number, borehole inclination angle, and drill bit type, and binds these parameters as data attribute identifiers to the acquired data. The drilling rig controller collects drilling data through sensors installed on the drilling rig, calculates the effective borehole depth based on the collected data, and packages the collected drilling data and the calculated effective borehole depth into a data package before transmitting the packaged data to the host computer. A dual-condition lock-in of the effective operating condition eliminates interference data from manual / idling operations. Once the drilling rig completes drilling and data acquisition is complete, the drilling rig controller switches the data acquisition mode to standby mode to monitor the drilling rig status in real time.

[0035] In special operating conditions, the wireless controller receives user commands and sends them to the drilling rig controller. The drilling rig controller uses these commands to determine the drilling rig's operating status: manual drilling or retraction, and switches the data acquisition mode to forced acquisition. Based on user commands, the drilling rig controller sets acquisition parameters, including tunnel length, borehole number, borehole inclination angle, and drill bit type, and stores these parameters as data attribute identifiers bound to the acquired data. The drilling rig controller collects drilling data through sensors installed on the drilling rig, packages the collected data, and transmits the packaged data to the host computer, comprehensively recording key scenario data such as retraction and escape (high lifting force) and manual emergency response (no automatic propulsion). Once the drilling rig completes drilling or retraction, data acquisition is complete, and the drilling rig controller switches the data acquisition mode to standby mode to monitor the drilling rig status in real time.

[0036] Emergency Scenario 1: In the event of a sudden incident at the drilling rig, the wireless controller receives user instructions and sends them to the drilling rig controller. The drilling rig controller then switches the data acquisition status from automatic to paused based on the user instructions. The drilling rig controller continues to collect drilling data through sensors installed on the drilling rig, but the effective drilling depth data is not updated and remains at the value from the previous automatic acquisition state. The controller also packages the collected drilling data and the effective drilling depth before the status switch into a data packet, blocking the data packet from being sent to the host computer. When the equipment malfunctions and is paused, invalid data segments (such as those caused by drill rod vibration during replacement) are isolated, eliminating the need for manual cleaning later.

[0037] Emergency Scenario 2: In the event of a sudden incident at the drilling rig, the wireless controller receives user instructions and sends them to the drilling rig controller. The drilling rig controller switches the data acquisition status from forced acquisition to data acquisition paused status based on the user instructions. The drilling rig controller continuously collects drilling rig data through sensors installed on the drilling rig and packages the collected drilling rig data into packets, blocking the transmission of data packets to the host computer. When the equipment malfunctions and stops, invalid data segments (such as vibration during drill rod replacement) are isolated, eliminating the need for manual cleaning later.

[0038] It should be noted that after an emergency at the drilling rig is resolved, the wireless controller receives user commands and sends them to the drilling rig controller. The drilling rig controller can then switch the data acquisition status from the paused state back to the forced acquisition state or the automatic acquisition state via user commands.

[0039] In this embodiment, the drilling rig data includes the propulsion stroke, propulsion speed, propulsion displacement, rotational torque, rotational speed, propulsion force, and pull-out force.

[0040] like Figure 4 As shown, the effective borehole depth is calculated based on the collected drilling rig data, specifically including the following steps: Step 1: Obtain the current drill pipe advance speed and advance displacement using a displacement sensor.

[0041] Step 2: Monitor the push limit position switch signal. If the push limit position switch signal is triggered, the current drill pipe push displacement is rounded off. The push limit position switch signal is a key physical indicator of whether the drill pipe has completed full-length drilling.

[0042] Step 3 involves calculating the overall effective drilling speed and displacement of the drill pipe based on the advance speed and displacement of each drill pipe, and accumulating the corrected standard displacement of each drill pipe to ensure the accuracy of the borehole depth calculation. This aggregated calculation strongly correlates data with construction progress (such as phased drilling), improving the accuracy of rock strata characteristic analysis (such as fault location) and construction scheme optimization (such as drilling rig parameter adjustment).

[0043] Step 4: Based on the initial borehole depth and the overall effective drill pipe advance displacement, the effective borehole depth is obtained. By integrating the initial depth value with the corrected overall effective displacement, the system can dynamically calculate the real-time borehole depth, replacing manual estimation or complex data fitting later. This calculation logic is directly related to the construction context (e.g., the initial depth corresponds to the completed borehole section), ensuring the continuity and traceability of depth data, and providing directly usable core indicators for geological exploration (e.g., rock stratum boundary location) and construction management (e.g., progress monitoring).

[0044] In this embodiment, the effective drilling depth is obtained by accumulating the initial drilling depth value with the overall effective advance displacement of the drill rod. The initial drilling depth value is obtained through a wireless remote control. For a new drill hole, the user can send a zeroing message to the drill controller via the wireless remote control to recalculate the effective drilling depth. For repeated drill holes, the user can send the accumulation history via the wireless remote control to restore the accumulation of the effective drilling depth for the drill hole.

[0045] In this embodiment, the push-to-limit position switch signal is monitored. If the push-to-limit position switch signal is triggered, the current drill pipe push-to-limit displacement is rounded and corrected. Specifically, this includes the following steps: Step S201 involves detecting the push-to-limit position switch signal. If the signal continues to trigger for a preset time, it is determined that the drill pipe has completed full-rod drilling. By monitoring the continuous trigger time of this signal, it is possible to automatically identify whether the drill pipe is in a stable working state and to round off the displacement data, eliminating mechanical slippage errors. This mechanism filters out abnormal fluctuation data during equipment start-up and shutdown, ensuring that only data under valid operating conditions is stored, reducing the difficulty of subsequent data processing.

[0046] Step S202: Obtain the current standard length L0 of the drill pipe and the current drill pipe advance displacement L. 1。

[0047] Step S203: Calculate the displacement error based on the current standard drill pipe length L0 and the current drill pipe advance displacement L1. The specific calculation method is as follows: , If displacement error If the current drill pipe advance displacement L1 is less than the predetermined threshold, the current drill pipe standard length L0 is corrected; otherwise, the effective drilling depth calculation is paused and an alarm is sent.

[0048] Example 2 This embodiment provides a system that utilizes the remote-controlled drilling rig data acquisition method described above, such as... Figure 5 As shown, it includes at least: Sensors are installed on the drilling rig to collect drilling data; The wireless remote control is used to receive user commands and transmit them to the drilling rig controller. The drilling rig controller is used to determine the working status of the drilling rig and dynamically switch the data acquisition working status based on the received user instructions, collect drilling rig data through sensors, and calculate the effective drilling depth based on the drilling rig data. The host computer is used to store the packaged data.

[0049] In this embodiment, the sensors include a system pressure sensor, a return oil pressure sensor, a propulsion displacement sensor, a rotation pressure sensor, a rotation speed sensor, a propulsion pressure sensor, and a propulsion limit position switch.

[0050] The system pressure sensor is installed at the oil inlet of the drilling rig valve assembly to collect the real-time working pressure of the drilling rig hydraulic system.

[0051] The return oil pressure sensor is installed on the return oil pipeline of the drilling rig valve assembly to collect the return oil pressure of the drilling rig hydraulic oil.

[0052] The thrust displacement sensor is installed on the piston rod of the thrust cylinder or the oil circuit of the thrust motor in the drilling rig valve group to collect the thrust speed and thrust displacement of each drill pipe.

[0053] The rotary pressure sensor is installed in the rotary motor inlet line of the drilling rig valve assembly to collect the rotary hydraulic pressure of the drilling rig. The rotary torque can be obtained by multiplying the rotary hydraulic pressure and the motor displacement.

[0054] The rotational speed sensor is installed on the output shaft of the drill rig's rotary motor to collect the rotational speed of the drill rod.

[0055] The propulsion pressure sensor is installed in the rodless chamber pipeline of the propulsion cylinder of the drilling rig valve group to collect the pressure in the propulsion direction of the drilling rig. The propulsion force and the pull-out force during the return stroke can be obtained by multiplying the propulsion pressure and the piston pressure.

[0056] The push limit position switch is installed at the end of the drill frame guide rail of the drilling rig and is used to collect position trigger signals to determine the push stroke.

[0057] In some of the illustrated embodiments, the wireless remote control is equipped with status indicator lights; The data acquisition is in automatic acquisition mode, and the status indicator light is flashing slowly. The data acquisition is in forced acquisition mode, and the status indicator light is flashing rapidly. The data acquisition is in standby mode, and the status indicator light is constantly on. The data acquisition is currently in the paused state, and the corresponding pause indicator light is on.

[0058] In summary, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
