Abstract
Description
Technical Field
[0001] The present invention relates to the field of computer vision technology, and particularly to a blasting hazard detection system based on UAV tomography. Background Art
[0002] Blasting hazard detection is a very important task, which mainly conducts a comprehensive safety inspection on the sites, equipment and operation procedures involved in blasting operations, aiming to discover and eliminate potential safety hazards and ensure the safety and controllability of blasting operations. This work is usually responsible for professional blasting engineers or safety management personnel, involving detailed inspections of various aspects such as blasting materials, blasting environment and operation specifications. Blasting operations are usually applied in fields such as mine exploitation, tunnel construction and water conservancy projects, and the geological conditions in these areas are complex and variable. The stability of rock masses is directly related to blasting safety, so it is necessary to conduct in-depth research on the structure, fracture distribution, mechanical properties, etc. of rock masses. Traditional geological exploration mainly relies on means such as manual drilling and ground penetrating radar, but these methods have problems such as low efficiency, high cost and limited coverage. In recent years, with the progress of rock mechanics theory and detection technology, high-precision geological modeling and hazard identification have become possible.
[0003] Prior Art One, Application No.: CN 202411019273.0 discloses a method for quickly detecting unexploded detonators at the post-blasting operation site, including a sticker-type wireless transmission device and a mobile detector supporting the wireless transmission device. The wireless transmission device is an RFID electronic tag; the wireless transmission device is loaded into the blasting hole together with the detonator. After blasting, if the detonator is successfully detonated, the sensor of the accompanying wireless transmission device will be damaged; if the detonator fails to blast, the sensor of the accompanying wireless transmission device will remain intact; the unexploded detonator receives the signal sent by the wireless transmission device through the mobile detector, so as to locate and find it at the blasting operation site. Although all detonator data can be completely collected, the accurate information such as the number and landing point of unexploded detonators can be safely and quickly detected, avoiding the safety hazards brought by the uncertainty of detecting unexploded detonators, and it is convenient to carry and operate, and is suitable for harsh environments such as chamber excavation; however, the installation of the wireless transmission device is relatively complex, and due to the effect of the detonator, it will cause certain interference to the operation of the wireless transmission device, and there are certain safety hazards for the detection of detonation.
[0004] Prior art two, application number: CN202310106600.5, discloses a mechanized combined drilling and blasting mining process and system for gypsum mines, including: selecting a target gypsum mining area, investigating and eliminating safety hazards at the top and bottom loose rocks of the target gypsum mining area; determining the working face of the target gypsum mining area after eliminating safety hazards, opening slotting holes on the working face, and blasting the slotting holes into slotted tunnels; obtaining a first hydraulic crushing device, positioning the crushing head of the first hydraulic crushing device perpendicular to the gypsum surface near the slotted tunnel, opening the crushing device until the gypsum is crushed, stopping the crushing operation, and obtaining collapsed gypsum rock; screening gypsum rock with a particle size larger than a preset threshold, and using the first hydraulic crushing device to perform secondary crushing on the screened rock until the particle size of the secondary crushed gypsum rock is smaller than the preset threshold. Although this reduces the use of civilian explosives, significantly weakens the harmful effects of various blasting methods, greatly improves safety, and significantly increases production efficiency, it still relies too heavily on the experience of professional personnel, which not only fails to improve the safety of blasting but also cannot effectively improve mining efficiency.
[0005] Existing technology three, application number: CN201810059286.9, discloses a method for dispatching and commanding blasting safety alerts using unmanned aerial vehicles (UAVs). This method utilizes the remote control and aerial hovering camera / photography functions of UAVs to collect real-time global or local image data of the blasting area and its surrounding environment. It enables real-time analysis of pre-blasting alert effects, monitoring of the blasting area's alert status, recording of the blasting process, inspection of post-blasting environmental impacts, identification and detection of misfires, and remote-controlled collection of misfire information, thereby achieving dispatching and commanding blasting safety alerts. While using UAV technology for dispatching and commanding blasting safety alerts improves the timeliness, safety, and reliability of blasting safety alerts and hazard identification and handling in blasting alerts, blasting area inspections, and misfire detection, ultimately achieving safe and efficient detonation and eliminating post-blast hazards, it focuses on many aspects and does not prioritize post-blast investigation, resulting in a need for further improvement in the accuracy of hazard identification.

The flight altitude adjustment submodule adjusts the UAV's flight altitude using the calculated basic parameters and signal reflection intensity, calculates the difference between the signal reflection intensity and the average value, thereby calculating the influence of angle adjustment on flight altitude, and further adjusts the flight altitude in conjunction with the influence of temperature on the speed of sound. Significance: Precise adjustment of flight altitude not only improves the safety of UAV flight but also enhances mission efficiency and accuracy. Analysis of signal reflection intensity helps UAVs identify and avoid obstacles, while considering the effect of temperature on the speed of sound ensures accurate mission execution under various environmental conditions. The integrated adjustment submodule, combining calculation results and the influence of the square root of the signal strength ratio and the sine function, yields the new adjusted flight altitude for the UAV. Significance: By comprehensively considering multiple factors (such as signal strength and temperature), UAV flight adjustments become more refined and intelligent. The introduction of the square root of the signal strength ratio and the sine function may be to account for the uneven distribution of signal strength in different directions and the influence of environmental factors on signal propagation, thereby achieving more precise altitude adjustment.

[0077] The standard deviation calculation submodule is responsible for calculating the standard deviation of the reflection intensity, which reflects the fluctuation and local changes of the signal;
[0078] The result synthesis calculation submodule is responsible for multiplying the weighted average result by the standard deviation to generate the final tomographic image; combining the global features and local changes of the signal, it generates a high-resolution image.
[0079] The expression for the tomographic image in the image generation module is as follows:
[0080] ;
[0081] In the formula, This represents the weighting coefficient, used to adjust the degree of influence of different parameters on the final result. The larger the weight, the more significant the influence of the corresponding parameter on the result; Indicates the reflected intensity of the signal, used to indicate the location. The intensity of the reflected signal received at the location; The time difference is used to represent the time delay from signal transmission to reception, and is usually related to the length of the signal propagation path. This represents a time parameter, used to describe the time characteristics of a signal, which may be related to the signal's propagation speed or attenuation characteristics; Represents rock mechanical property parameters, used to indicate the location The mechanical properties of the rock (such as elastic modulus, density, etc.) are used to correct signal attenuation; Describes the layering structure parameters, used to indicate the location The geological stratification structure at the location is used to adjust the signal reflection characteristics; This represents the signal's timing parameters, which may be related to the signal's propagation time or temporal resolution. These parameters represent the bedding structure and may be related to the angle or direction of geological bedding. These parameters represent the mechanical properties of rocks and may be related to the physical properties of rocks (such as porosity and permeability). It represents the ratio of reflection intensity to time difference, used to express the reflection intensity per unit time. This represents the initial reflection intensity value generated by the weighted average. This represents the final generated tomographic image, used to indicate the location. The first part calculates the reflection intensity value at a given location. The weighted average part generates a preliminary reflection intensity value by integrating parameters such as reflection intensity, time difference, rock mechanical properties, and bedding structure. Its function is to extract global features of the signal and optimize the influence of parameters through weight allocation, ensuring the accuracy and physical meaning of the calculation results. The standard deviation part quantifies the fluctuation and local variation of reflection intensity. By calculating the deviation between the reflection intensity and the preliminary reflection intensity value, the standard deviation reflects the local details and anomalous areas of the signal, enhancing the image's detail information and providing local features for subsequent image generation. By considering both signal reflection intensity and time difference, as well as geological structure and rock mechanical properties, a high-resolution fault image is ultimately generated. This method allows for more efficient processing of point cloud data and the generation of more accurate and detailed images.
[0082] The working principle and beneficial effects of the above technical solution are as follows: The weighted average calculation submodule of this embodiment performs weighted average calculation on parameters such as signal reflection intensity, time difference, geological structure, and rock mechanical properties to generate a preliminary reflection intensity value; the standard deviation calculation submodule calculates the standard deviation of the reflection intensity, reflecting the fluctuation and local changes of the signal; the result synthesis calculation submodule multiplies the weighted average result with the standard deviation to generate the final fault image; combining the global features and local changes of the signal, a high-resolution image is generated. The weighted average calculation submodule of the above solution performs weighted average calculation on multiple key parameters such as signal reflection intensity, time difference, geological structure, and rock mechanical properties to generate a preliminary reflection intensity value; through the allocation of weights, it ensures that important parameters have a greater impact on the results, thereby improving the accuracy of the calculation; combining parameters such as rock mechanical properties and bedding structure, it performs attenuation correction and structural adjustment on the signal to ensure that the physical meaning of the signal is reasonably reflected. The significance of this approach: The weighted average calculation submodule extracts global features from complex signals, providing fundamental data for image generation. Through weighted averaging, it effectively reduces the impact of noise and outliers, improving data reliability and stability. Combined with geological and rock mechanics properties, it ensures that the generated reflection intensity values have clear physical meaning, providing a scientific basis for geological analysis. The standard deviation calculation submodule quantifies signal fluctuations and local variations by calculating the standard deviation of reflection intensity, reflecting detailed information in the image. Standard deviation reveals the dispersion of data distribution, helping to identify anomalous or highly variable areas in the signal. As an indicator of local variation, standard deviation can be combined with the weighted average results to further enhance image detail and resolution.
