Description

Technical Field

[0001] This invention belongs to the field of coal mine underground automated drilling rig control technology, and relates to a mobile control terminal for an underground automated drilling rig centralized control operation line in coal mines. Background Technology

[0002] Currently, automated drilling operations are becoming increasingly common in coal mines. To improve drilling efficiency and safety, centralized control lines are gradually being adopted to manage multiple drilling rigs centrally. Traditional drilling rig control methods mainly rely on wired operating consoles or fixed control cabinets, requiring operators to control the drilling rig from fixed locations via cables.

[0003] In existing technologies, drilling rig centralized control systems generally suffer from the following problems: First, the control equipment is mostly fixed, which prevents operators from moving it flexibly, resulting in inconvenience in operation in complex downhole environments and low work efficiency; second, a large number of control cables need to be laid, which are complex to install, difficult to maintain, and easily damaged by harsh environments such as humidity and dust downhole; third, it is difficult for operators to view the downhole operation site video in real time, making it impossible to intuitively grasp the actual working status of the drilling rig; fourth, fault information feedback is not timely, and operators often have to wait for system alarms or on-site inspections to discover problems, affecting the safety and continuity of operations.

[0004] In addition, existing mobile control equipment has limited functionality, typically only supporting basic parameter display and simple control. It cannot simultaneously meet the comprehensive needs of remote and precise control of multiple drilling rigs, real-time video monitoring, and intelligent fault push notifications, making it difficult to adapt to the high-efficiency and safe operation requirements of centralized control lines for automatic drilling rigs in coal mines.

[0005] Therefore, there is an urgent need to develop a portable, functionally integrated mobile control terminal that can reliably access existing centralized control ring networks to solve the above-mentioned technical problems. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a mobile control terminal for an automatic drilling rig centralized control operation line in a coal mine.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A mobile control terminal for an automatic drilling rig centralized control operation line in a coal mine includes an Android tablet terminal and an intelligent drilling rig mobile monitoring APP software installed on the Android tablet terminal. The APP software achieves remote control communication with the downhole drilling rig and auxiliary devices through the central server. The central server receives the remote control commands issued by the APP and sends them to the corresponding devices according to the IP address of the drilling rig and the IP address of the delivery device in each drilling site. The APP software includes: The login and binding module is used to record the device identifier and complete the binding upon the first login, enabling automatic login thereafter. The voice call module is used to enable real-time voice calls between terminals; The data monitoring module is used to present multiple independent drilling site options and display the on-site operation status in real time; The mobile control module is used to send remote start / stop control commands to the central server and uses distributed data synchronization control technology algorithms to achieve multi-user concurrent control. The mobile control module has multiple linkage control modules set at the bottom of the APP interface, which correspond to multiple "drilling rigs + auxiliary". Each group of equipment has two basic operation states: "start" and "stop". The control commands include the highest priority emergency stop control command.

[0008] Furthermore, the distributed data synchronization control technology algorithm of the mobile control module is specifically as follows: When any online user issues a start or stop command by clicking any linkage control button through a mobile control terminal, the system captures the command in real time and assigns it a priority identifier (emergency stop control command has the highest priority). Upon receiving the instruction, the central server immediately performs a state switch and broadcasts the latest device status after the switch to all online mobile control terminals via WebSocket, achieving real-time consistency of device status updates across the entire network. Meanwhile, the central server provides feedback confirmation on the execution results of the control commands. If the execution fails, it pushes a failure alarm message to the terminal that issued the command.

[0009] Furthermore, the mobile control module also includes a control access management submodule and a misoperation prevention protection submodule; The control permission management submodule assigns control permissions according to the role of the backend account, and only authorizes users to issue control commands to the specified drilling site equipment. The anti-misoperation protection submodule pops up a secondary confirmation dialog box after the user clicks the control button, and requires voice confirmation in conjunction with the voice call module before the final command can be issued, further ensuring the safety of downhole operations.

[0010] Furthermore, the data monitoring module works in conjunction with the mobile control module: After the user selects any drilling site on the data monitoring interface, the system will simultaneously display the real-time status information of the drilling rig, the performance indicators of the delivery equipment, and the on-site operation view of that drilling site. The mobile control module only applies to the currently monitored drilling site to prevent accidental control across drilling sites. Only one drilling site can be monitored and controlled at a time, and the data monitoring interface is refreshed immediately after the control operation to display the latest equipment status.

[0011] Furthermore, the APP software also includes a terminal operation log recording function, which is specifically used to record the entire process information of mobile control operations, including control command type, priority, issuance time, operator, target device, execution result and feedback confirmation status, and stores it in the database through a central server for the background to perform security audits and accountability.

[0012] Furthermore, the central server transmits control commands to the drilling rig and auxiliary devices using the HTTP / HTTPS protocol, and the APP software transmits control commands and provides real-time status feedback to the central server using the WebSocket protocol. The Android tablet terminal is equipped with a 64-bit Android operating system and supports low-latency mobile control requirements in explosion-proof environments in coal mines.

[0013] Furthermore, the emergency stop control command of the mobile control module has the highest global priority. Once issued, the central server immediately interrupts all other current control commands and prioritizes the emergency stop operation to ensure that the safe response time in an emergency downhole does not exceed 2 seconds.

[0014] The beneficial effects of this invention are as follows: (1) This invention provides a portable mobile control terminal that integrates a drilling rig control module, a field video monitoring module and a fault information push module, thereby enabling wireless remote control of the coal mine underground automatic drilling rig centralized control operation line. This effectively solves the problems of inconvenient operation and difficult maintenance caused by fixed control equipment and the need to lay a large number of cables in the prior art.

[0015] (2) After the present invention is connected to the drilling rig control line ring network, it can cover all drilling rigs in the work site without the need for additional control cables, which significantly simplifies the on-site wiring work, reduces the risk of cable damage, and improves the system reliability.

[0016] (3) The present invention can control multiple drilling rigs at the same time and display the drilling rig connection status, permission status and various operating parameters in real time. Operators can remotely complete various precise operations and parameter settings of the drilling rig, which greatly improves the flexibility of operation and work efficiency.

[0017] (4) This invention supports real-time display of downhole operation site video, enabling operators to intuitively grasp the actual working status of the drilling rig. Combined with the intelligent fault information push function, it realizes timely detection and handling of faults, significantly improving the safety and continuity of operation.

[0024] Example 1 Figure 1 This is a schematic diagram of the overall structure of the mobile control terminal for the centralized control line of the automatic drilling rig in coal mines according to the present invention. Figure 1 As shown, the mobile control terminal includes a portable terminal body 1, which integrates a drilling rig control module 2, a field video monitoring module 3, and a fault information push module 4. The portable terminal body 1 is connected to the drilling rig centralized control network 6 via a WiFi wireless communication unit 5, enabling wireless communication with multiple automatic drilling rigs 7 at the work site.

[0025] The drilling rig control module 2 is used for remote control of the drilling rig and display of operating parameters. The on-site video monitoring module 3 is used for real-time display of on-site video of downhole operations. The fault information push module 4 is used for receiving and displaying drilling rig fault warning information.

[0026] Figure 2 This is a schematic diagram showing the connection relationship of the software functional modules of the mobile control terminal of the present invention. For example... Figure 2 As shown, the drilling rig control module 2 interacts with the on-site video monitoring module 3 and the fault information push module 4, and the three are connected to the WiFi wireless communication unit 5 through the communication interface module.

[0027] The specific workflow of the mobile control terminal in this embodiment is as follows: The operator first activates the portable terminal 1. The terminal automatically connects to the drilling rig's central control network 6 via WiFi, scanning and displaying the connection and permission status of all connectable automatic drilling rigs 7 at the work site. After the operator selects up to three drilling rigs to be controlled, the drilling rig control module 2 establishes a stable communication link.

[0028] Subsequently, the drilling rig control module 2 receives and displays in real time the operating parameters of each drilling rig on the terminal screen, including the pressure of the main pump, the pressure of the small pump, the propulsion pressure, the pressure of the main manipulator, the pressure of the auxiliary manipulator, the oil temperature, the oil level, the rotation speed, the real-time propulsion speed, the maximum propulsion speed, the waiting time for ventilation and water, the drilling depth, the displacement of the power head, the horizontal displacement, the vertical displacement, the frame height, and the system pressure.

[0029] The operator sends control commands through the drilling rig control module 2, which can execute the following actions: feed forward rotation, feed reverse rotation, rear clamp clamping, rear clamp loosening, front clamp clamping, front clamp loosening, front clamp forward swing, front clamp reverse swing, engagement, disengagement, advance displacement, auxiliary hand displacement reset, main hand clamping, main hand loosening, main hand swing in, main hand swing out, main hand extension, main hand retraction, main hand tilt angle increase, main hand tilt angle decrease, main hand vertical, main hand horizontal, frame tilt angle increase, frame tilt angle decrease, vibration on, discharge forward rotation, discharge reverse rotation, water valve opening, negative pressure extraction. The following operations are included: clamping the transfer trough, loosening the transfer trough, extending the transfer trough, retracting the transfer trough, opening a new hole, completing drilling, increasing the rotation speed, decreasing the rotation speed, setting point A, setting point B, clamping the auxiliary hand, releasing the auxiliary hand, extending the auxiliary hand, retracting the auxiliary hand, moving the auxiliary hand forward, moving the auxiliary hand backward, directional left, directional right, lifting the machine frame, lowering the machine frame, linkage, single action, drilling, walking, automatic drilling, automatic unloading of drill bits, starting, emergency stop, air circuit switch, water circuit switch, spray switch, water dust removal switch, air dust removal switch, and diaphragm pump switch.

[0030] Simultaneously, the on-site video monitoring module 3 synchronously calls up and displays up to two channels of downhole operation video footage, enabling operators to intuitively observe the actual working status of the drilling rig. If a fault occurs during drilling rig operation, the fault information push module 4 immediately receives the early warning information pushed by the ring network and highlights it on the terminal interface, reminding operators to handle it promptly.

[0031] In this embodiment, the mobile control terminal runs on a portable device with Windows 10 or Windows 11 operating system installed. Its drilling rig control module 2, on-site video monitoring module 3, and fault information push module 4 are developed and implemented based on C# language, using Visual Studio 2022 development tools and the .NET 8.0 framework.

[0032] Example 2 Figure 3 This is a schematic diagram of the workflow of the mobile control terminal of the present invention in automatic drilling mode.

[0033] like Figure 3As shown, in an automated drilling operation scenario, the operator selects the target drilling rig and enters the automated drilling mode via a mobile control terminal. The drilling rig control module 2 first sends commands to complete the point A and point B positioning operations, determining the starting and ending positions of the borehole. Then, it sequentially executes steps such as raising or lowering the rig frame to a suitable height, swinging the main arm forward, preparing the propulsion displacement, and activating the linkage mode.

[0034] During automatic drilling, the drilling rig control module 2 continuously monitors key parameters such as real-time advance speed, drilling depth, and rotation speed, and automatically adjusts the rotation speed by increasing or decreasing it according to preset thresholds. At the same time, the on-site video monitoring module 3 displays real-time video of the drilling process, and the fault information push module 4 monitors and pushes early warnings in real time for possible faults such as excessively high oil temperature and abnormal system pressure.

[0035] Once the drilling depth reaches the set value, the drilling rig control module 2 automatically executes the drilling completion command, and then enters the automatic drill unloading process, including operations such as releasing the main handle, uncoupling, rotating the discharge forward or reverse, and extending the transfer chute. The entire process requires no continuous operator intervention, only remote monitoring and necessary intervention via a mobile control terminal, significantly reducing the intensity of downhole operations.

[0036] Example 3 Figure 4 This is a schematic diagram of the interface and data flow of the mobile control terminal of the present invention when multiple drilling rigs are controlled collaboratively.

[0037] like Figure 4 As shown, in this embodiment, the mobile control terminal simultaneously connects to and controls three automatic drilling rigs. The drilling rig control module 2 displays the connection status, operating parameters, and control buttons of the three drilling rigs on a single interface. Operators can independently switch control permissions for each drilling rig, enabling time-sharing or parallel operation.

[0038] When one of the drilling rigs malfunctions, the fault information push module 4 displays the fault details in a prominent position on the terminal. At the same time, the on-site video monitoring module 3 can quickly switch to the video screen of the malfunctioning drilling rig, making it easier for operators to determine the cause of the fault and remotely execute protection operations such as emergency stop.

[0039] This embodiment fully demonstrates the technical solution of the present invention, which highly integrates the three major functions of drilling rig control, video monitoring and fault early warning into the portable terminal body. By connecting to the drilling rig centralized control line ring network, it can achieve coverage control of all drilling rigs in the work site without the need for additional control cables, which significantly improves the flexibility, safety and intelligence of the coal mine underground automatic drilling rig centralized control operation line.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
