Description

Technical Field

[0001] This invention relates to the field of simulation training technology, specifically an immersive four-sided projection rock drilling rig simulation training method. Background Technology

[0002] Rock drilling rigs are widely used equipment in mines, but novice employees face numerous challenges in practical training with them. For example: Location: Mining areas and project sites are often remote, shift work is frequent, and centralized training is costly. Safety: Novice operators are prone to accidents such as collisions, misoperation, rollovers, and crushing. Rock drilling conditions include high-risk scenarios such as roof / sidewall risks and collision avoidance in confined spaces. Cost: On-site training occupies production equipment, resulting in significant downtime losses and noticeable wear and tear on fuel, consumables, tires, and drill bits. Training efficiency: Abnormal malfunctions and extreme working conditions are difficult to reproduce reliably on real equipment, leading to insufficient emergency response training. Training effectiveness: Traditional simulators only provide some operational and visual feedback, failing to allow operators to truly experience the underground working conditions of the rock drilling rig, such as the pitching and tilting of the equipment during movement, and the vibrations and noises during drilling.

[0003] Therefore, there is an urgent need for a training method that can provide safe, reliable, realistic, and immersive training to improve the training efficiency and safety of operators. Summary of the Invention

[0004] To address the problems of existing technologies, this invention provides an immersive four-sided projection rock drilling rig simulation training method, which offers a safe, reliable, realistic, and immersive training solution to improve the training efficiency and safety of operators.

[0005] This invention provides an immersive four-view projection rock drilling rig simulation training method, comprising the following steps: 1) Design a training plan, use a rock drilling rig to operate the machine according to the training plan, and record the data of different models of rock drilling rigs operating in different environments; 2) Input the collected data into the central data processing module of the simulation training equipment; 3) Trainees enter the trolley simulation cabin, select the simulation equipment model, and perform simulated operations according to the selected equipment model. The simulated operation content includes component recognition, individual training options, and operation assessment; the individual training options and operation assessment content specifically include simulated driving and simulated drilling. 3.1) Simulated driving, the specific process is as follows: 3.11) Simulate key insertion, cab instruments self-test, equipment powers on; 3.12) Turn the key to the ignition position. The system checks whether the emergency stop is activated, the parking brake is engaged, and the gear is in neutral. If not, the system screen will display the parts that need to be reset. If yes, proceed to the next step. 3.13) When the engine starts, the corresponding speed is displayed on the instrument panel on the projection screen, and the dynamic base simulates the vibration of the equipment. The projection equipment retrieves the actual machine operation data, projects the current environment, and displays the route on the front and rear projection screens. 3.14) The trainee shall engage forward or reverse gear according to the route instructions, release the parking brake, and press the accelerator pedal; 3.15) The projection equipment retrieves the actual machine operation data, and the four-sided projection screen simulates the dynamic picture of the equipment moving, and simulates the corresponding engine noise according to the throttle position; 3.16) The dynamic base simulates the actual working conditions of the equipment during actual operation based on real machine operation data, including equipment acceleration, bumps caused by encountering potholes on the road, collisions with rock walls, bumps on up and down slopes, overall equipment shaking, and tilting in all directions. 3.17) Once the equipment reaches the designated destination, park and turn off the engine; mission complete. 3.2) Simulated drilling: Trainees operate the lever to perform actions, and the projector projects the corresponding actions based on the actual operation data, while the motion base provides the corresponding vibration; 4) After completing the training, the trainees turn off the simulation equipment and leave the trolley simulation chamber.

[0006] Further improvements include, in step 1), the data including dynamic images of the surrounding environment, sound effects, cockpit vibration levels, and cockpit position changes.

[0007] Further improvements include, in step 3), component recognition, which includes recognition of main components, recognition of control panel components, and recognition of safety facility components.

[0008] Further improvements are made to the simulated drilling process described in step 3.2), which is as follows: 3.21) Perform boom positioning. After positioning is completed, the system will prompt you to start drilling. 3.22) Ensure the small hole or enlargement knob is in the desired position, place the boom and push beam in the drilling position, and firmly press the push beam pin against the rock; the screen will display the corresponding position, and simulate equipment vibration after contact; 3.23) Use the water flushing or air flushing control lever to start the water flushing; the screen displays the water flushing and simulates the flushing sound; 3.24) Move the control lever forward, and the rock drill rod will start to rotate. The four-sided projected screen simulates the dynamic scene of the rock drill rod rotating, and provides slight vibration. 3.25) Move the forward control lever to start advancing. The four-sided projection screen simulates the changes in the position of the drill bit and rock drill, causing the drill bit to hit the rock. When the drill bit hits the rock, the advancing pressure increases and the equipment vibration increases. 3.26) Move the impact control lever to the middle position, start the low impact pressure, and the moving base simulates the impact vibration of a rock drill, emitting an impact sound. 3.27) After the drill bit penetrates the rock, the impact control lever is moved to the forward position to activate high impact pressure. The screen displays that high propulsion pressure is automatically obtained, and the vibration and sound increase accordingly. 3.28) When the rock drill reaches the front end of the feed beam, the impact is automatically shut off and reverse propulsion begins; when the rock drill reaches the rear end position, the rotation control lever, feed control lever and impact control lever are moved to the neutral position, and drilling is completed; 3.29) After drilling is completed, the boom is repositioned and the process returns to the beginning step, and the operation is repeated.

[0009] Further improvements, in step 3), include a specific structure for the simulation equipment, comprising a trolley simulation chamber mounted in the center of the cabin via a motion base. The motion base has multiple degrees of freedom and several sensors. The trolley simulation chamber is equipped with a sound system and a rock drilling trolley simulator operation panel. The rock drilling trolley simulator operation panel controls the movement direction of the motion base and the movement of the virtual rock drilling trolley robotic arm. The sound system provides corresponding sound effects based on the data from the sensors on the motion base. Several ultra-short-throw projectors are installed on the top of the cabin, and the four inner walls of the cabin serve as projection screens. The ultra-short-throw projectors acquire information from the sensors on the motion base and project simulated images onto the projection screens. Simultaneously, they acquire operation information from the rock drilling trolley simulator operation panel and simulate the movement of the rock drilling trolley robotic arm in the simulated images.

[0010] The beneficial effects of this invention are as follows: 1. The training method adopted in this invention can overcome the difficulty of conducting immersive training for operators on the mining site, reduce personnel training costs, and eliminate the need for personnel training to be conducted upon entering the construction site, thereby effectively improving on-site safety.
