Such solutions are equipped with a variety of sensors to achieve real-time monitoring of multiple dynamic parameters such as temperature, humidity, gas concentration, vibration, etc. This diversified monitoring method has greatly enhanced the forward-looking early warning capability of mine safety. However, in the existing technology, there is a lack of in-depth capture of nonlinear deformation and its impact on mine safety, and the verification and validity assurance mechanism of the collected data is also weak, resulting in missing or untrue data in some cases, thereby affecting the accuracy of judgment.

Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other accompanying drawings can be obtained based on these accompanying drawings without paying creative work.

[0019] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0020] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a method for collecting mine safety monitoring information, comprising: S1: Dynamic parameters in the mine tunnel are collected collaboratively through environmental sensors. During the collection process, a digital signature containing a unique device identifier is attached to each data packet.

[0021] Furthermore, environmental sensors include vibration sensors, gas sensors, and temperature and humidity sensors; S2: When it is detected that the parameter value of any sensor exceeds the preset threshold, the high-precision deformation measurement device is activated to scan the target area, and the timestamp and operator identity credentials are embedded in the trigger instruction.

[0022] Furthermore, a hardware-level trigger link is established between sensor groups, specifically including: electrically connecting the output signal end of the gas concentration sensor to the intelligent control module of the laser scanning device to form a direct signal transmission channel; when the gas concentration sensor detects that the target parameter exceeds the preset warning level, a pulse trigger signal is generated and transmitted to the logic control unit of the laser scanning device through the electrical connection channel; after the logic control unit analyzes the pulse signal, it starts the scanning head rotation mechanism of the laser scanning device to drive the scanning head to perform multi-angle measurement of the associated area along the preset trajectory; during the multi-angle measurement process, the scanning head rotation mechanism dynamically adjusts the scanning elevation angle according to the geometric contour characteristics of the tunnel roof, so that the laser beam coverage area forms a spatial match with the gas concentration abnormal area; at the same time, the parameter change trend of the gas concentration sensor is monitored in real time during the measurement process. If the detection value shows a downward trend within a continuous measurement cycle, the laser scanning device is controlled to switch to a low-power standby mode; the data of the multi-angle measurement is transmitted to the central processing module through a parallel processing channel, and is bound to the spatiotemporal tag of the gas concentration sensor for storage.

[0023] S3: Send detection signals to the rock formation and synchronously collect reflected signals and vibration data, and perform frame encryption processing on the original waveform data.

[0024] Furthermore, a collaborative working mechanism of the acoustic wave transmitting component and the vibration sensor is configured. At the beginning of the measurement cycle, the central processing module sends a start instruction to the acoustic wave transmitting component, and the acoustic wave transmitting component generates a detection signal with specific frequency band characteristics according to the instruction parameters; in the detection signal transmission stage, the vibration sensor enters a low sampling rate monitoring mode and continuously collects environmental background vibration data; when the detection signal transmission is completed, the acoustic wave receiving component enters a reflection signal capture stage, and the central processing module sends a mode switching instruction to the vibration sensor to make it enter a high-frequency sampling mode; the high-frequency sampling mode and the reflection signal capture stage adopt a clock synchronization mechanism, and a synchronization pulse signal is sent to the acoustic wave receiving component and the vibration sensor through the precision clock source of the central processing module to ensure that the time scales of the collected data of the two are accurately aligned; in the data storage stage, the characteristic parameters of the reflection signal are associated and packaged with the original waveform data of the vibration sensor in the corresponding time period to form a multimodal data set with a unified time reference; when it is detected that the vibration sensor has data missing in the synchronization period, the adjacent redundant vibration sensor is automatically triggered to collect data, and the complete data set is reconstructed through an interpolation algorithm.

[0025] S4: Generate a rock mass state model based on signal correlation, calculate spatial deformation information based on scanning data, and perform key segmentation and storage on model parameters.

[0026] Furthermore, the acoustic wave reflection signal is aligned with the acceleration spectrum collected by the vibration sensor in the time domain to generate a characteristic parameter matrix, which is input into the finite element analysis framework together with the three-dimensional deformation vector obtained by laser scanning, wherein: the acoustic wave parameters are mapped to the internal crack density coefficient of the rock mass, the vibration spectrum energy distribution is used to correct the rock mass elastic modulus parameters, and the three-dimensional deformation vector is used as a boundary constraint condition; a rock mass state model is generated.

[0027] A scanning device capable of dynamically adjusting the measurement sites is deployed, and a mobile scanning platform with a multi-degree-of-freedom robotic arm is installed in the tunnel, with a laser ranging module at the end of the robotic arm. In the initial measurement stage, a reference scanning path is generated through the point cloud data obtained by scanning, and the robotic arm is controlled to move along the path and collect basic deformation data. In the continuous monitoring stage, the gradient change characteristics of the historical deformation data are analyzed in real time, and when it is detected that the deformation rate of the local area exceeds the set deformation threshold, a new scanning path planning instruction is automatically generated. The new scanning path planning instruction includes: increasing the scanning point density in the high deformation area, extending the dwell measurement time of the key parts, and adjusting the incident angle of the laser beam to avoid obstacles. During the path execution process, the posture sensor of the robotic arm feeds back the angle data of each joint in real time, calculates the spatial coordinates of the end ranging module through the inverse kinematics algorithm, and performs fusion and calibration with the output data of the inertial navigation module. The calibrated spatial coordinate data is input into the deformation calculation model, and combined with the initial coordinate value of the reference scanning stage, a three-dimensional deformation vector diagram with millimeter-level accuracy is generated.

[0028] It should be noted that the deformation calculation model is based on the point cloud data of the initial scanning stage. The principal axis direction of the tunnel is determined by principal component analysis (PCA) to construct a local rectangular coordinate system. The difference method is used to process the deviation between the real-time scanning coordinates and the initial coordinates. The calculation formula is: ; in, is the coordinate difference, is the coordinate of the i-th measuring point at time t, is the initial coordinate; the displacement vector of each measuring point is interpolated according to the spatial position to generate a three-dimensional deformation vector diagram.

[0029] S5: Perform logical verification on the measurement results through the multi-source data cross-validation module and verify the validity of the data signature.

[0030] Furthermore, a physical constraint relationship library between sensor data is constructed to define the positive correlation constraint between the vibration amplitude change rate and the tilt angle change rate, the inverse proportional constraint between the gas concentration gradient and the air flow rate, and the linear constraint between the temperature change rate and the thermal conductivity of the rock mass. In the verification stage, the parameter values ​​in the current measurement cycle are extracted from the multi-source data set, and it is calculated whether their combination relationship meets the preset constraint conditions. When a constraint violation is detected, the following operations are performed: an abnormal event marker is generated and the specific constraint item that is violated is recorded; a verification request instruction is sent to the redundant sensor group within a preset range around the abnormal area; after receiving the instruction, the redundant sensor group starts the enhanced measurement mode to collect the same type of parameter data at a higher sampling frequency; the central processing module performs weighted fusion processing on the original data and the verification data. When the difference between the verification data and the original data exceeds an acceptable range, the original data is marked as invalid and the data source fault diagnosis process is triggered.

[0031] S6: The verified measurement data is integrated with the dynamics to generate a visual monitoring map, and the detailed disclosure level of the map is controlled based on attribute permissions.

[0032] It should be noted that the three-dimensional space model is a multi-layer structure model, including the geometric layer, attribute layer, dynamic layer and topological layer; Among them, the geometric layer is generated by laser scanning point cloud data with an accuracy of ±1mm; the attribute layer embeds the monitoring parameters of each spatial position including gas concentration, temperature gradient and rock state model output results; the dynamic layer updates the deformation vector field data in real time; the topological layer records the spatial relationship between the tunnel support structure, equipment position and benchmark markers.

[0033] Furthermore, an environmental isolation component is provided at the output end of the optical path of the measuring device, and an annular gas nozzle array is installed on the periphery of the emission window of the laser ranging module, and the nozzle array is connected to the high-pressure gas source through a flexible pipeline; in the measurement startup phase, the solenoid valve is controlled to open so that the high-pressure gas passes through the nozzle to form a conical air curtain barrier surrounding the laser beam; in the measurement process, the dust concentration sensor is used to monitor the deposition state of particulate matter outside the air curtain in real time, and when it is detected that the deposition thickness reaches the deposition threshold, the air curtain flow is controlled to increase to the cleaning mode, and the rotating scraping mechanism is started to physically clean the emission window surface; after the cleaning operation is completed, the window cleanliness is evaluated by the optical transmittance detection module, and if the standard is not met, a maintenance alarm signal is triggered; all environmental isolation status data are stored synchronously with the measurement data for error compensation calculation in subsequent data analysis.

[0034] It should be noted that spatial reference markers are arranged in the target area, and physically unclonable function (PUF) chips are embedded in the spectral characteristic markers installed in the alley. The PUF chip of each marker generates a unique characteristic response code during the initialization phase, and pre-stores the response code hash value in the central database; during the laser scanning phase, the scanning device reads the spectral characteristics and PUF response code of the marker, and performs the following security verification operations: first, the marker type is determined by spectral characteristic matching, and then a random challenge signal is sent to the PUF chip. After receiving the response code, its matching degree with the pre-stored hash value is calculated; when the matching degree is lower than 75%, it is determined that the marker may have been tampered with or replaced, and the following disposal measures are performed: the position of the abnormal marker is marked in the visual map, the scanning device in the adjacent area is triggered to re-measure the three-dimensional morphology of the marker, and the abnormal event log is encrypted and transmitted to the security audit module; the physical installation location information of all PUF chips is bound and stored with the three-dimensional model of the alley, and when an unauthorized position coordinate change is detected, the data fusion processing flow of the relevant area is automatically frozen.

[0035] Furthermore, when the spatial distribution information of the marker is obtained through a mobile scanning platform, an end-to-end encrypted transmission channel is established, specifically including: deploying a quantum key distribution (QKD) module between the multi-spectral imager carried by the drone and the ground data processing center to generate a temporary session key to encrypt the imaging data; in the data alignment stage, a double verification mechanism is implemented: the first verification is based on the comparison of the PUF response code of the marker with the pre-stored database, and the second verification is to detect whether the three-dimensional point cloud data has been tampered with through the digital watermark technology; when the double verification is passed, the following security fusion operations are performed: the encrypted imaging data and laser scanning data are decrypted in the trusted execution environment (TEE) and spatial coordinate conversion is performed. The coordinate transformation matrix used in the conversion process is dynamically generated by the hardware security module (HSM) and is valid for one time; after the alignment is completed, the plaintext data in the TEE is immediately cleared and the key seed of the HSM is updated; if an abnormal access request is detected during the alignment process, the zero-knowledge proof protocol is initiated to verify the requester's authority, and the final alignment result can only be output after the proof is passed.
