[0044] Example 1: High-rise building facade cleaning operation
[0045] System configuration: In this embodiment, the virtual reality system uses a head mounted display (HMD) with a resolution of 2880×1600 pixels and a display frequency of 90Hz to ensure the smoothness and clarity of the picture. The dynamic platform consists of a high-precision sensor and an electric drive system. The platform size is 1.2 meters × 1.2 meters. The platform tilt angle is adjustable with a maximum tilt angle of 45 degrees. The platform can provide a maximum vibration feedback of 10Hz according to the weight and operating performance of the operator.
[0046] Operation process: The operator enters the virtual environment through a head-mounted display and sees the facade of a high-rise building, about 100 meters above the ground. The operator needs to complete the task of cleaning the facade. During the operation, the wind speed in the virtual environment is simulated to 10m / s and the temperature is simulated to 5℃ to increase the realism of the operation. During the operation, the operator may slip or lose his footing. At this time, the dynamic platform will provide simulated feedback of falling, with a tilt angle of 20 degrees, and vibrate to simulate the impact of falling.
[0047] Safety protection feedback: When the operator does not wear a safety belt or does not adjust the safety rope correctly, the safety protection feedback system will monitor the operator's equipment wearing status in real time and warn through the red warning prompt of the head-mounted display, the vibration feedback of the dynamic platform and the sound prompt. At this time, the system will ask the operator to readjust the wearing method of the safety belt and safety rope.
[0048] Example 2: Overhead power line maintenance work
[0049] System configuration: In this embodiment, the virtual reality system uses a head mounted display (HMD) with a resolution of 2560×1440 pixels and a display frequency of 75Hz. The dynamic platform has a size of 1.5 meters × 1.5 meters and can simulate a free fall distance of up to 3 meters. The platform tilt angle is adjustable, with a maximum tilt angle of 50 degrees. The vibration intensity is dynamically adjusted according to the behavior of the operator, and the maximum vibration frequency is 12Hz.
[0050] Operation process: The operator wears a head-mounted display to enter the virtual environment. The virtual scene is an overhead power line, about 50 meters above the ground. The operator needs to complete the maintenance task of the power equipment. At this time, the wind speed simulated by the system is 15m / s, and the power equipment fault simulation function in the virtual environment is automatically enabled. The system will require the operator to perform emergency processing according to the equipment fault condition. During the processing, the operator must quickly respond to the system prompts and repair the equipment fault.
[0051] Risk emergency feedback: In a virtual environment, when operators operate improperly or encounter sudden equipment failures, the system will simulate the operator's slip and fall. The dynamic platform will tilt to the maximum angle (50 degrees) and provide 10Hz vibration feedback to simulate the free fall process of the operator after losing balance.
[0052] Safety protection feedback: During this process, the safety protection system monitors the wearing of safety belts and safety ropes by the operators, and when any abnormality is found, it reminds the operators to check the safety protection equipment in time through visual warnings, sound prompts and vibration feedback.
[0053] Working principle:
[0054] The simulated free-falling virtual reality somatosensory high-altitude work safety protection experience device of the present invention combines virtual reality technology, somatosensory feedback technology and safety protection monitoring system, simulates the high-altitude work environment through an integrated design, and provides an immersive virtual experience and real-time somatosensory feedback. Its working principle can be divided into the following parts:
[0055] Virtual reality system: Workers wear high-resolution virtual reality head-mounted displays (HMDs) to enter a computer-generated virtual environment for high-altitude operations. The system presents real three-dimensional virtual scenes based on different operation scenarios (such as high-rise building facades, power lines, etc.), and updates the images in real time through dynamic rendering technology to enhance the workers' sense of immersion.
[0056] Free fall simulation module: This module consists of a dynamic platform and sensors. The dynamic platform simulates the actual free fall process according to the operation or action of the operator in the virtual environment. When the operator slips or falls in the virtual environment, the dynamic platform will adjust the platform's tilt angle and vibration intensity according to the set height and speed changes, thereby truly simulating the operator's free fall and impact feeling.
[0057] Safety protection feedback system: The system uses sensors to monitor the status of the safety belts, safety ropes and other protective equipment worn by the operators, and checks the safety protection measures of the operators in real time. When the safety belts, ropes and other equipment are worn incorrectly or loose, the system will warn the operators through visual, sound or vibration prompts to remind them to make adjustments.
[0058] High-altitude work simulation environment: According to the requirements of different work tasks, the system provides multiple virtual environment scenes (such as building facades, overhead power lines, etc.). Each scene is designed according to real working conditions, and operators can choose different scenes for training.
[0059] Risk emergency training module: The system simulates a variety of high-risk situations, such as equipment failures and emergencies, to help operators conduct emergency response training in a virtual environment. The system will provide feedback based on the operator's response actions and evaluate their emergency response speed and handling capabilities.
[0060] The entire system achieves realistic simulation and safety training of aerial work through precise real-time feedback and intelligent operation. Operators can accumulate practical emergency experience in a simulated environment, and improve their emergency response capabilities and safety awareness.
