Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a method, apparatus, equipment, and storage medium for simulating the multi-mode movement of a coal mining machine. Background Technology

[0002] Currently, fully mechanized mining technology is relatively mature in coal seam mining, but there is a lack of verification and analysis of the safe operation performance of coal mining machines.

[0003] In existing technologies, some solutions construct a three-machine working face drive system and a matching three-dimensional full working face test model to realize the real machine drive system driving the three-dimensional model for testing and verification of the electro-hydraulic control system of the working face. The three-machine working face drive system inputs real data generated during operation and uses the test model program to output interference and fault information, thereby improving the testing and verification capability of the electro-hydraulic control system. This method introduces a method of using a three-machine (coal mining machine, scraper conveyor, and hydraulic support) driver program to drive a three-dimensional model to verify the function of the electro-hydraulic control system (support control system) through test simulation. However, this method lacks the ability to simulate without a driver program or with an incomplete driver program, and it relies on the equipment model for display. Furthermore, this method does not decompose the coal mining machine walking simulation function; it simply transplants the real machine program and cannot perform simple coal mining machine walking simulation, arbitrary trajectory design and planning, or trajectory input / output, thus lacking full-function walking simulation. Moreover, this method cannot be flexibly modularized and combined with other simulation equipment to support testing in different scenarios.

[0004] In addition, some schemes involve setting up a rotary table, a test platform, a coal mining machine's traveling track, a simulated coal shovel, a triaxial force loader, and a safety winch. The coal mining machine's traveling track, triaxial force loader, and safety winch are all fixed on the test platform, which is elongated. The coal mining machine's traveling track is laid along the length of the test platform. The simulated coal shovel is supported by several vertical hydraulic cylinders and installed on the test platform, arranged parallel to the coal mining machine's traveling track. The two ends of the vertical hydraulic cylinders are hinged relative to the simulated coal shovel and the test platform, respectively. The safety winch is located near one end of the coal mining machine's traveling track. The test platform is laid flat and fixed on the rotary table. Initial support force is provided by the hydraulic cylinders to achieve spatial triaxial loading force. The real-time state of the coal mining machine under stress is collected during the model's movement to verify the safety of the coal mining machine's movement. 1. This method introduces a physical test platform for a coal mining machine, aiming to simulate a real-world scenario for testing. It cannot perform software-based simulations, does not reflect software simulation testing theory and methods, and cannot conduct software simulation experiments.

[0005] Another approach involves setting up a comprehensive testing platform for the coal mining machine. This platform is a scaled-down version of the actual test equipment, serving as a model test bench. It includes a test platform, a coal mining machine travel track, a simulated shovel, a triaxial force loader, and a safety winch. The coal mining machine travel track and safety winch are fixedly mounted on the test platform, while the triaxial force loader is detachably mounted. The simulated shovel and test platform are hinged to the hydraulic cylinders and arranged parallel to the coal mining machine travel track. The movement of the coal mining machine is simulated in the laboratory, with the hydraulic cylinders providing the track's self-movement force, to test the machine's movement and the track system. This method, which uses a model test bench, has low simulation accuracy and limited ability to simulate coal mining machine movement, and also cannot be used for software simulation experiments. Summary of the Invention

[0006] This invention provides a method, apparatus, equipment, and storage medium for simulating the multi-mode movement of a coal mining machine. It aims to independently design the movement trajectory of the coal mining machine, achieve decoupling from the real machine system, and is simple, fast, and efficient to operate.

[0007] Therefore, the first objective of this invention is to provide a method for simulating multi-mode movement of a coal mining machine, comprising:

[0008] The reference position during the movement of the coal mining machine is used as the trigger point for the movement trajectory of the coal mining machine to simulate the movement trajectory of the coal mining machine;

[0009] According to the movement mode of the coal mining machine, the movement trajectory of the coal mining machine is configured to determine the movement mode of the coal mining machine;

[0010] Based on the mining process of the coal mining machine, the walking mode of the coal mining machine is selected to realize the simulation of multi-mode walking of the coal mining machine.

[0011] In the step of designing the coal mining machine's travel trajectory to conform to the actual conditions of an underground coal mine, the support number of the hydraulic support set on the coal mining machine's travel path is used as a reference position. The combination of "trigger point + coal mining machine direction" data is used as the basis for dividing the coal mining machine's operating stages. All coal mining machine operating stages are combined together to form the complete travel trajectory of the coal mining machine, thus designing a coal mining machine travel trajectory that conforms to the actual conditions of an underground coal mine.

[0012] Among them, the process of configuring the trajectory of the coal mining machine according to its movement mode includes:

[0013] Configure the starting point of the motion to simulate the position where the coal mining machine begins to move;

[0014] Configure the direction of movement to simulate the upward or downward movement of the coal mining machine, and determine the starting direction of the coal mining machine's movement.

[0015] Configure the coal mining machine speed, and design the support travel time and speed parameters; among them, the support travel time is a global rapid configuration parameter that simulates the time it takes for the coal mining machine to pass through a support, and then calculates the speed of the coal mining machine; the speed parameters are set for each stage in the stage configuration mode;

[0016] Configure the acceleration of the coal mining machine to simulate the rate of speed change.

[0017] In the process of configuring the coal mining machine's travel trajectory, three mutually exclusive travel modes are set: rapid configuration, standard one-cut coal, and staged configuration; among them,

[0018] In quick configuration mode, the starting point of movement, direction of movement, and walking time are configured to determine a set of stage trigger points. The coal mining machine walks at a constant speed and automatically determines the walking direction based on the current stage and the next stage.

[0019] In the standard one-cut coal mode, eight coal mining machine state stages are designed, using the starting point of movement, direction of movement, stage trigger point, stage speed and up and down acceleration. The travel range and state of each stage are designed, and the acceleration for state switching is designed.

[0020] In the stage configuration mode, an arbitrary trajectory design method is implemented, with the configuration being the same as that of the standard one-cut coal.

[0021] The coal mining machine's walking modes include the central following mode and the full working face following mode.

[0022] In the simulation of the middle section following mode: the movement of the coal mining machine in the middle section is simulated. The trajectory is simulated through the quick configuration mode and the stage configuration mode. Two stages of bidirectional movement in the middle section are designed to simulate the movement state. In the field operation, the middle section following mode only involves the division of two stages, namely the middle section upward movement and the middle section downward movement. The starting point, direction, speed, and movement range of the coal mining machine are designed to complete the configuration of the middle section following mode.

[0023] When simulating the full-face following mode: the walking status of the coal mining machine during the entire mining cycle can be simulated using the quick configuration mode, standard one-cut coal mode, and stage configuration mode. The standard one-cut coal mode is only applicable to mining processes where the coal mining machine makes one oblique cut. When the number of cuts in the full-face following process is multiple / the number of oblique cuts at both ends of the working face is different / other cut methods are used, the quick configuration and stage configuration modes are used.

[0024] The second objective of this invention is to provide a device for simulating the multi-mode movement of a coal mining machine, comprising:

[0025] The walking trajectory simulation module is used to simulate the walking trajectory of the coal mining machine by using the reference position during the walking process as the trigger point of the walking trajectory of the coal mining machine.

[0026] The walking mode determination module is used to configure the walking trajectory of the coal mining machine according to its walking mode and determine the walking mode of the coal mining machine.

[0027] The walking simulation module is used to select the walking mode of the coal mining machine according to the mining process, and realize the simulation of multiple walking modes of the coal mining machine.

[0028] A third objective of the present invention is to provide an electronic device comprising: at least one processor; and a memory communicatively connected to the at least one processor; wherein the memory stores instructions executable by the at least one processor, the instructions being executed by the at least one processor to enable the at least one processor to perform the steps of the method described above.

[0029] A fourth objective of this invention is to provide a non-transitory computer-readable storage medium storing computer instructions, wherein the computer instructions are used to cause a computer to perform the steps of the method according to the foregoing technical solution.

[0030] Unlike existing technologies, the method for simulating multi-mode movement of a coal mining machine provided by this invention simulates the movement trajectory of the coal mining machine by using reference positions during the movement process as trigger points; configuring the movement trajectory according to the movement mode of the coal mining machine to determine the movement mode; and selecting the movement mode of the coal mining machine based on the mining process, thereby simulating multi-mode movement of the coal mining machine. This invention allows for independent design of the coal mining machine's movement trajectory, achieving decoupling from the actual machine system, and is simple, fast, and efficient to operate.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] This invention describes a method for simulating the movement of a coal mining machine. Without relying on other software (real machine system or drivers) and equipment, it can independently simulate all functions and business scenarios of a coal mining machine's movement. By inputting key parameters of the coal mining machine's movement, a customizable movement trajectory can be designed. The testing tool broadcasts the movement status of the coal mining machine in real time, achieving the simulation function. Using this method, the movement trajectory of the coal mining machine can be designed independently, achieving decoupling from the real machine system. It is simple to operate, fast and efficient, and also has the ability to perform cluster testing with other testing systems.

[0040] Other testing systems refer to simulation software, real machine systems and equipment with communication functions, including hydraulic supports, scraper conveyors, transfer conveyors, crushers, pump stations and other related equipment.

[0041] Full functionality refers to all motion attribute parameters of the coal mining machine; functional scenarios include coal mining face business scenarios, including thin coal seams, medium-thick coal seams, high mining heights, and top coal caving business scenarios.

[0042] Figure 1 A method for simulating multi-mode movement of a coal mining machine, provided in an embodiment of the present invention, includes:

[0043] Step S110: Use the reference position during the movement of the coal mining machine as the trigger point for the movement trajectory of the coal mining machine, and simulate the movement trajectory of the coal mining machine.

[0044] The simulation of the coal mining machine's movement trajectory involves simulating the machine's movement along the track on the scraper conveyor. The direction of movement is either upward or downward along the track (upward towards the larger end of the support number, downward towards the smaller end). The reference point for the movement is generally the hydraulic supports within the working face, and the machine's position is indicated by the support numbers on the hydraulic supports. The simulation of the coal mining machine's movement must consider its functionalities and the operational scenario. The movement functions include communication functions and operational functions (communication functions refer to communication with related equipment; operational functions refer to the machine's movement, coal cutting, etc.). The operational scenario refers to the type of fully mechanized mining face. The combination of these two factors forms the specific process of the coal mining machine's movement. This testing software tool simulates the coal mining machine's movement process.

[0045] This invention simulates the movement trajectory of a coal mining machine. First, a movement trajectory that conforms to on-site conditions is designed to simulate on-site operational needs. In the technical solution of this invention, the reference position (support number) during the movement of the coal mining machine is used as the trigger point for the movement trajectory. The combination of "trigger point + coal mining machine direction" data is used as the basis for dividing the operation stages of the coal mining machine. All operation stages of the coal mining machine are combined to form the complete movement trajectory of the coal mining machine.

[0046] Step S120: Configure the trajectory of the coal mining machine according to its travel mode and determine the travel mode of the coal mining machine.

[0047] The trajectory configuration process includes:

[0048] Configure the starting point of the motion to simulate the position where the coal mining machine begins to move;

[0049] Configure the direction of movement to simulate the upward or downward movement of the coal mining machine, and determine the starting direction of the coal mining machine's movement.

[0050] Configure the coal mining machine speed, and design the support travel time and speed parameters; among them, the support travel time is a global rapid configuration parameter that simulates the time it takes for the coal mining machine to pass through a support, and then calculates the speed of the coal mining machine; the speed parameters are set for each stage in the stage configuration mode;

[0051] The acceleration of the coal mining machine was configured to simulate the rate of speed change. In addition, the following parameters were also configured:

[0052] Movement range: Design "maximum value" and "minimum value" to indicate the range of the coal mining machine's travel and cruising.

[0053] Cyclic motion: A cyclic switch is designed. When the switch is turned on, the coal mining machine moves continuously along the trajectory. When the switch is turned off, the coal mining machine moves along the trajectory once (one process cycle).

[0054] This invention establishes three mutually exclusive walking modes: rapid configuration, standard one-cut coal, and staged configuration; wherein,

[0055] In quick configuration mode, the starting point of movement, direction of movement, and walking time are configured to determine a set of stage trigger points. The coal mining machine walks at a constant speed and automatically determines the walking direction based on the current stage and the next stage.

[0056] In the standard one-cut coal mode, eight coal mining machine state stages are designed, using the starting point of movement, direction of movement, stage trigger point, stage speed and up and down acceleration. The travel range and state of each stage are designed, and the acceleration for state switching is designed.

[0057] In the stage configuration mode, an arbitrary trajectory design method is implemented, with the configuration being the same as that of the standard one-cut coal.

[0058] Step S130: Select the walking mode of the coal mining machine according to the mining process of the coal mining machine, and realize the simulation of multi-mode walking of the coal mining machine.

[0059] The coal mining machine's travel modes include the middle-face following mode and the full-face following mode.

[0060] like Figure 2 As shown, when simulating the middle section following mode: the movement of the coal mining machine in the middle section is simulated. Trajectory simulation is performed through quick configuration mode and stage configuration mode. Two stages of bidirectional movement in the middle section are designed to simulate the movement state. In field operations, the middle section following only involves the division of two stages, namely the middle section upward movement and the middle section downward movement. The starting point, direction, speed, and movement range of the coal mining machine are designed to complete the configuration of the middle section following.

[0061] When simulating the full-face following mode: Simulate the movement of the coal mining machine throughout the entire mining cycle. The quick configuration mode, standard one-cut coal mode, and stage configuration mode can be used for simulation. The standard one-cut coal mode is only applicable to mining processes where the coal mining machine makes one oblique cut. When the number of cuts in the full-face following process is multiple / the number of oblique cuts at both ends of the working face is different / other cut methods are used, the quick configuration and stage configuration modes are used.

[0062] Figure 3 The diagram shows the standard single-cut coal configuration method for the entire working face. Following this method, it is necessary to configure the motion state attributes of the coal mining machine, including the starting point, direction, trigger points for the eight stage transitions, speed, and acceleration for speed changes. The figures show the numbers representing the trigger points for the eight stage transitions and one starting point.

[0063] Using quick configuration and stage configuration, other mining processes can be configured, supporting the design of new coal mining machine travel processes using this tool.

[0064] Figure 4The diagram illustrates a non-standard following-machine process (other mining processes), specifically the arbitrary movement trajectory of the coal mining machine mentioned in this method. The trajectory shown has 11 stages, with stage trigger points (support numbers) of 90, 70, 85, 70, 80, 70, 90, 40, 1, 20, and 10. Following this method, it is necessary to configure the coal mining machine's starting point, direction, stage switching trigger points for the 11 stages, and motion state attributes such as speed and acceleration for speed changes.

[0065] like Figure 5 As shown, the present invention proposes a device 300 for simulating the multi-mode movement of a coal mining machine, comprising:

[0066] The walking trajectory simulation module 310 is used to simulate the walking trajectory of the coal mining machine by using the reference position during the walking process as the trigger point of the walking trajectory of the coal mining machine.

[0067] The walking mode determination module 320 is used to configure the walking trajectory of the coal mining machine according to the walking mode of the coal mining machine, and determine the walking mode of the coal mining machine.

[0068] The walking simulation module 330 is used to select the walking mode of the coal mining machine according to the mining process of the coal mining machine, so as to realize the simulation of multi-mode walking of the coal mining machine.

Configure the coal mining machine speed, and design the support travel time and speed parameters; among them, the support travel time is a global rapid configuration parameter that simulates the time it takes for the coal mining machine to pass through a support, and then calculates the speed of the coal mining machine; the speed parameters are set for each stage in the stage configuration mode; Configure the acceleration of the coal mining machine to simulate the rate of speed change; Three mutually exclusive walking modes are defined: rapid configuration, standard one-cut coal, and staged configuration; wherein, the walking mode determination module is further used for: In quick configuration mode, the starting point of movement, direction of movement, and walking time are configured to determine a set of stage trigger points. The coal mining machine walks at a constant speed and automatically determines the walking direction based on the current stage and the next stage. In the standard one-cut coal mode, eight coal mining machine state stages are designed, using the starting point of movement, direction of movement, stage trigger point, stage speed and up and down acceleration. The travel range and state of each stage are designed, and the acceleration for state switching is designed. In the stage configuration mode, an arbitrary trajectory design method is implemented, with the configuration being the same as that of the standard one-cut coal.
