Description

Technical Field

[0001] The present invention relates to the technical field of drilling rescue, and particularly to a drilling rescue ultra-wideband radar life detection imaging system and method. Background Art

[0002] Under complex rescue conditions, existing drilling rescue technologies face many technical challenges. Traditional life detection technologies such as audio-video detection and infrared detection have poor effects when penetrating complex geological structures such as rocks, soil, and debris accumulations. Due to the attenuation and scattering of detection signals in complex environments, it is difficult to accurately locate deeply trapped personnel with these technologies, resulting in the inability to obtain vital sign information in a timely manner, thus affecting the rescue efficiency and success rate.

[0003] Existing life detection devices have significant deficiencies in terms of accuracy and real-time performance. In complex rescue environments, traditional technologies are easily interfered with, leading to false alarms or missed detections. At the same time, the data processing and transmission systems usually have delays and cannot provide timely feedback on detection results, prolonging the rescue decision-making time and thereby increasing the risks for trapped personnel.

[0004] Operational complexity is also a major bottleneck for traditional drilling rescue equipment. These devices often require professional operators, and their complex settings and large structures make it difficult to quickly deploy and use them after a disaster, wasting valuable rescue time.

[0005] Existing life detection technologies include audio life detection technology, video life detection technology, infrared thermal imaging detection technology, gas detection technology, and ultra-low frequency electromagnetic wave life detection technology, but these technologies have deficiencies in terms of penetration ability, detection accuracy, and real-time performance. For example, FLIR series infrared thermal imagers perform poorly in high-temperature or low-temperature environments and are easily interfered by environmental temperature, resulting in inaccurate detection results; audio-video technology is limited by light and noise environments and is difficult to penetrate obstacles; while ultra-low frequency electromagnetic wave technology, although having a certain penetration ability, still has limitations in detection accuracy and real-time performance.

[0006] Existing UWB radar drilling rescue devices generally include an ultra-wideband radar detector, a data transmission line, a tripod, a wireless communication module, and a host computer. The information collected by the ultra-wideband radar detector is transmitted to the wireless communication module through the data transmission line and then transmitted wirelessly to the host computer for processing and display. However, the current technical limitation is that the display effect of the host computer can only present the processed waveform data and lacks an intuitive three-dimensional image display function. Rescue personnel must analyze the waveforms to understand the detection results, resulting in low efficiency.

[0007] The prior art is a detector with a rotatable probe, with a publication number of CN221199966U, which has a 360° rotation detection function and can provide detection information from multiple angles and in all directions. However, its display is still mainly based on two-dimensional data and lacks three-dimensional visualization effects.

[0008] Another technology, with a publication number of CN115356714B, provides a simulation analysis method for personnel positioning through the research on the transmission law of UWB radar waves in different coal rock masses. Although it is helpful for theoretical research, there are still certain limitations in practical applications and it is difficult to meet the requirements for real-time and accurate display in complex rescue scenarios.

[0009] Although the prior art has made significant progress in vital sign detection, there are still deficiencies in the intuitiveness and interactivity of information presentation. Especially in the real-time display of three-dimensional images, it cannot provide a more intuitive display of vital information. Summary of the Invention

The display screen 3-5-6 is installed in the central part of the module, is directly connected to the lens group 3-5-5, and is fixed to the module through the display screen bracket 3-5-7. The display screen bracket 3-5-7 is located outside the module and serves as a structure for fixing the display screen, connecting to the display screen 3-5-6 and the housing to ensure stable position.

[0038] The system can capture the user's eye movements in real time and dynamically adjust the display angle of the image accordingly. The camera module 3-5-1 and the image sensor 3-5-2 are used in combination to accurately monitor the movement trajectory of the user's eyes, ensuring real-time feedback on the line-of-sight direction. The reflective polarizer 3-5-3 and the semi-reflective projection film 3-5-4 reduce environmental light interference, ensuring the accuracy and response speed of eye tracking. Even under complex light conditions, the system can still operate stably. The lens group 3-5-5 further enhances the capture accuracy of eye movements, ensuring that even subtle changes in the user's line of sight can be recognized by the system and the image adjusted. The display screen 3-5-6 automatically adjusts the display content of the image according to the user's eye movement feedback, enabling rescue personnel to quickly and accurately switch the viewing angle and view different areas of life information without manual operation. This design greatly improves the operation efficiency and user experience of the system, especially suitable for emergency rescue scenarios.

[0060] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0061] Embodiment 1:

[0088] The optical projection module 3-2 is responsible for projecting the visualized image transmitted by the life information detection unit 1 into the user's field of view. This module consists of a micro projector, high-resolution optical lenses, and a series of reflective optical elements. The micro projector has high-efficient data processing capabilities and can quickly project the received life information in front of the user to ensure real-time display. The high-resolution optical lenses are used to adjust and focus the projection light, enabling the image to remain clear at different viewing angles, which is particularly important in complex rescue environments. The reflective optical elements, through precise optical path design, ensure that the image can present a stable and high-quality projection effect in different orientations, allowing rescue personnel to observe life information at any time without frequently adjusting the device's position. This design significantly improves the visibility and operational convenience of the image in a dynamic environment.

The CPU and GPU work together to efficiently process data and image rendering to ensure that there is no delay or blurring when rescue personnel view the life information image. The ISP is responsible for further optimizing the image details so that the generated three-dimensional life information image can maintain high resolution at all times. At the same time, this module has the ability to dynamically adjust and can automatically switch and adjust the viewing angle according to the user's eye movement and line of sight direction, enabling rescue personnel to easily switch and view life information in different directions without manual operation.

The graphics generator 3-4-2 generates real-time life information images and dynamically adjusts the display content according to data changes. The drive assembly 3-4-3 controls the projection path and angle of the light to ensure that the user can see the complete image from any angle. The polarizer 3-4-4 and the retroreflective assembly 3-4-5 further enhance the brightness and contrast of the image, reduce the interference of ambient light on the projection effect, and enable the image to be presented more intuitively and clearly in front of the rescue personnel. The swing assembly 3-4-6 is responsible for adjusting the imaging area according to the user's head movement or line of sight direction to ensure that the user always obtains the optimal life information display at different viewing angles.

[0091] As Figure 6 As shown, the eye movement tracking module 3-5 captures the user's eye movements in real time through the camera module 3-5-1, the image sensor 3-5-2, the reflective polarizer 3-5-3, the semi-reflective projection film 3-5-4, the lens group 3-5-5, the display screen 3-5-6, and the display screen bracket 3-5-7, and dynamically adjusts the display angle of the image accordingly. The camera module 3-5-1 and the image sensor 3-5-2 are used in combination to accurately monitor the movement trajectory of the user's eyes and ensure real-time feedback on the line of sight direction. The reflective polarizer 3-5-3 and the semi-reflective projection film 3-5-4 reduce the interference of ambient light to ensure the accuracy and response speed of eye tracking. Even under complex lighting conditions, the system can still operate stably. The lens group 3-5-5 further magnifies the capture accuracy of eye movements to ensure that even the slightest changes in the user's line of sight can be recognized by the system and the image can be adjusted. The display screen 3-5-6 automatically adjusts the display content of the image according to the user's eye movement feedback, enabling the rescue personnel to quickly and accurately switch the viewing angle and view different areas of life information without manual operation. This design greatly improves the operation efficiency and user experience of the system, especially suitable for emergency rescue scenarios.

[0092] The wireless communication module 3-6 integrates Wi-Fi, Bluetooth, and 5G communication chips and supports multiple communication protocols. It is responsible for data exchange with the reel wireless communication unit 2, receiving real-time data transmitted from the life information detection unit 1, and transmitting the processed feedback information back.

[0096] The life information display unit 3 uses optical projection and aerial imaging technology to convert life information into three-dimensional images and project them into the user's field of vision. The optical path of the projection process can be described by the following formula:

[0097]

[0098] where d is the size of the projected image, f is the focal length of the projection system, S is the size of the projection light source, and D is the projection distance. By adjusting these parameters, the image projection display effect can be optimized.

After retrieving the life information detection unit (1), turn off the power of the super-surface drilling rescue perspective detection device, and the detection is completed; Step 7: After the mission is completed, all collected data is saved in the storage device of the life information display unit (3). After the mission is completed, the rescue personnel will play back and analyze the data to obtain more in-depth life information or use it for subsequent rescue decisions. After the data analysis is completed, the system is reset and archived according to the rescue needs for next use.
