Description

Technical Field

[0001] The present invention relates to the technical field of drilling rig control, and in particular to a drilling rig wireless control system, a drilling rig and a control method. Background Art

[0002] With technological advancements and increasingly sophisticated engineering requirements, drilling rigs are becoming smaller and more modular to flexibly cope with more complex working environments. A drilling rig consists of a drill rig body and a power unit. The drill rig body includes at least a frame, a drill pipe rotation system, and a hydraulic system. The drill pipe rotation system is used to rotate the drill pipe and drill bit. The hydraulic system uses a hydraulic variable oil pump to convert the engine's mechanical energy into hydraulic energy, thereby driving the rotation, pressurization, and lifting of the drill string. The power unit consists of an air compressor and an engine that drives the air compressor. The air compressor's output is connected to the drill rig body via a pipeline. The engine drives the air compressor to provide compressed air to the drill rig body for air drilling and air vibration drilling.

[0003] In complex working environments (such as mountainous and hilly areas), the placement of the power unit is a big problem. For safety reasons, it is often placed away from potential dangers such as landslides and mudslides. However, this means that the main body of the drilling rig and the power unit may be hundreds of meters apart, making the management of the control harness particularly difficult. Traditional modular drilling rig control systems rely on a large number of wired connections, which not only increases the complexity of the system, but also drives up costs, and makes installation and use inconvenient. In addition, the control harness may be damaged due to complex terrain, which in turn affects the normal operation of the drilling rig and may even cause safety accidents. Too many harnesses also cause troubles in transportation, installation and reorganization, reducing construction efficiency.

[0004] Although wireless control solutions exist in the existing technology, they are mainly limited to one-to-one remote control between the operator and the drill rig. Wireless control technology between the units of modular drill rigs is still blank, and these solutions usually cannot meet the special needs of complex terrain.

[0005] In traditional wireless control solutions, the application of wireless modules is relatively limited and limited. These wireless modules are primarily used as data exchange tools, responsible for transmitting information between the drilling rig and other equipment or systems. They do not directly participate in the control process of the drilling rig's power module, but rather act as an "information bridge," transmitting critical data from one part to another. After data exchange, it is converted into control instructions through a wired system, a process that can increase system response time. In drilling operations that require rapid response, any delay can lead to reduced efficiency or safety risks.

[0006] Some systems cannot achieve one-to-many control, which limits flexibility and scalability; they lack the function of quickly binding and unbinding power units, and cannot quickly adjust the drilling rig configuration according to actual needs; at the same time, they do not have 4G communication and satellite positioning capabilities, and cannot perform real-time remote monitoring and provide precise location information, which limits their application in complex environments. Summary of the Invention

[0121] The binding process includes: the wireless host controller obtains the coding / identification code of the wireless slave controller to be bound, sends a binding agreement through the communication address of the wireless slave controller in the coding / identification code, and the binding agreement includes the coding / identification code of the wireless slave controller to be bound and the coding / identification code of the wireless host controller. The wireless slave controller receives the binding agreement and judges the binding agreement. If the coding / identification code in the binding agreement is consistent with its own coding / identification code and the wireless slave controller and the wireless host controller are in an unbound state, the wireless slave controller responds to the wireless host controller to accept the binding; otherwise, it does not respond to the wireless host controller.

[0122] The unbinding process includes: the wireless host controller obtains the coding / identification code of the wireless slave controller to be unbound, sends an unbinding protocol through the communication address of the wireless slave controller in the coding / identification code, and the unbinding protocol includes the coding / identification code of the wireless slave controller to be unbound and the coding / identification code of the wireless host controller. The wireless slave controller receives the unbinding protocol and judges the unbinding protocol. If the coding / identification code in the unbinding protocol is consistent with its own coding / identification code and the wireless slave controller and the wireless host controller are in a bound state, the wireless slave controller responds to the wireless host controller to accept the unbinding; otherwise, the wireless slave controller does not respond.

[0123] The operator configures one or more drilling rig power modules for the main body of the drill rig based on the construction site and construction requirements. One or more drilling rig power modules form a power unit group. The main body control unit installed on the main body of the drill rig establishes a wireless communication connection with the drilling rig power modules in the power unit group.

[0124] Step S2, obtaining external data and operation instructions;

[0125] The details are as follows:

[0126] Transmit external data and operation instructions to the main control computer through the remote control 3 and the remote control transceiver corresponding to the remote control and connected to the main control part 1;

[0127] The master computer determines whether the command is for controlling the drilling rig's power unit. If so, it transmits the command to the wireless master controller, which then transmits the command to the corresponding wireless slave controller in a wireless communication connection. The slave controller then controls the corresponding power unit based on the command. If not, the master computer controls the drilling rig's main body based on the command.

[0128] Step S3, obtaining the total power required for construction based on external data and operation instructions, and determining the number M of power units required for construction by presetting the total load rate;

[0129] The details are as follows:

[0130] The main control computer obtains the total power required for construction based on external data and operational instructions. It then determines the number of power units M required for construction by presetting the total load factor. The total load factor consists of a minimum load factor α and a maximum load factor β. The ratio of the total power required for construction to the total power provided by the M number of power units is γ, with α≤γ≤β. In this embodiment, the minimum load factor α = 30% and the maximum load factor β = 80%.

[0131] Step S4, based on the number M of power units required for construction, the main control computer sends instructions to the corresponding number of wireless slave controllers in the drilling rig power modules through the wireless host controller, and the wireless slave controller controls the corresponding power units to provide power to the drilling rig body based on the instructions.

[0132] The specific steps include:

[0133] Step S401, obtaining the number N of drilling rig power modules in a wireless communication connection state;

[0134] Step S402: Based on the number M of power units required for construction and the number N of drilling rig power modules, the corresponding power units are controlled to operate by the wireless slave controller. Specifically,

[0135] If M = N, the master controller sends instructions to the slave wireless controllers in all the rig power modules in the wireless communication state through the wireless host controller, and the slave wireless controllers control the corresponding power units to provide power to the rig main body based on the instructions;

[0136] If M < N, the master controller sends instructions to the slave wireless controllers in all the rig power modules in the wireless communication state through the wireless host controller. The slave wireless controllers with the quantity of M - N control the corresponding power units to stop providing power to the rig main body based on the instructions, and the slave wireless controllers with the quantity of N control the corresponding power units to provide power to the rig main body based on the instructions;

[0137] If M > N, an alarm signal is issued.

[0138] Preferably, as Figure 8 shown, it further includes:

[0139] Step S5, collect the status data of the power units of the rig power modules in the wireless communication connection state, and obtain the quantity η of the rig power modules with power units in abnormal working conditions;

[0140] Obtain the ratio γ′ of the total power required for construction to the total power provided by the power units with the quantity of N - η. If γ′ > β, an alarm signal is issued;

[0141] If α ≤ γ′ ≤ β, control the rig power modules in abnormal working conditions to be in the sleep state;

[0142] If γ′ ≤ α, control the rig power modules in abnormal working conditions and the rig power module with the longest working time to be in the sleep state.

[0143] Step S6, the wireless main controller detects the working state of the rig main body through the sensors arranged on the rig main body, and transmits the detection data to the cloud or the remote server through the 4G communication module configured on the wireless main controller;

[0144] The slave wireless controllers in the bound state with the wireless main controller detect the working state of the rig power units through the sensors arranged on the rig power units, and transmit the status data to the wireless main controller and the master controller through the wireless communication connection. The wireless main controller transmits the detection data to the cloud or the remote server through the 4G communication module.

[0145] Step S7, the positioning module configured on the wireless host controller obtains the position of the rig main body in real time, and transmits the rig main body position data to the cloud or the remote server through the 4G communication module.

[0146] In short, 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 in the scope of protection of the present invention.
