For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0038] The implementation details of the technical solution of this application are described in detail below:

[0039] Figure 1 The flowchart of the method for locating personnel in a coal mine based on safety monitoring according to an embodiment of the present application is shown. Figure 1 As shown, the coal mine underground personnel positioning method based on safety monitoring includes at least steps S110 to S140, which are described in detail as follows:

[0040] In step S110, an infrared device is deployed underground in a coal mine.

[0041] In one embodiment of the present application, the infrared device can collect infrared images and ambient temperature of the target personnel, determine the infrared radiation value and thermal radiation profile of each person, match it with the information in the database, and realize identity recognition. Combined with the location information of the infrared device, the specific location of the target personnel can be tracked in real time, providing important data support for underground personnel management.

[0042] In one embodiment of the present application, the infrared device can monitor without direct contact with the target person, reducing the risk of cross infection. The infrared device can still maintain stable operation in the complex and changeable environment of the coal mine and has strong adaptability. Combined with artificial intelligence technology, the infrared device can realize automated and intelligent monitoring and management, and improve the safety production level of coal mines.

[0043] In step S120, when the target personnel go down the well, the infrared image and ambient temperature of the target personnel are collected by the infrared device, and the infrared radiation value and thermal radiation profile of each person are determined and stored in a database.

[0044] like Figure 2 As shown, in one embodiment of the present application, when the target personnel go down the well, the infrared image and ambient temperature of the target personnel are collected by the infrared device, and the infrared radiation value and thermal radiation profile of each person are determined, and stored in association in the database, including:

[0045] S210, when the target person goes down the well, collecting an infrared image of the target person, and detecting a human body temperature and a thermal radiation profile corresponding to the infrared image;

[0046] S220, obtaining the ambient temperature, and calculating the infrared radiation value of each person according to the human body temperature, the thermal radiation profile and the ambient temperature;

[0047] S230, associating the infrared radiation value of each person with the thermal radiation profile of the employee, and storing the associated infrared radiation value and the thermal radiation profile of the employee in a database.

[0048] In one embodiment of the present application, the collected infrared image is preprocessed to ensure the accuracy and reliability of the data, and then the infrared image is recognized to determine the body temperature and contour of the target person in the infrared image, so as to determine the infrared radiation value and the infrared radiation contour. Specifically, the infrared radiation value is determined according to the infrared radiation value calculation method, and the infrared radiation contour is determined according to the image extraction algorithm.

[0049] In this embodiment, after the infrared image is acquired, the infrared radiation value IR(x, y) corresponding to each pixel in the image can be determined based on the pixel value of each pixel in the infrared image and the ambient temperature:

[0050]

[0051] Among them, a, b, c and d are coefficients obtained by calibration of experimental data, I max and I min are the maximum and minimum pixel values ​​in the infrared image, I(x,y) is the pixel value of the infrared image at position (x,y), and T env is the ambient temperature.

[0052] Afterwards, the thermal radiation contour of the target person is segmented from the infrared image, and the average value of the infrared radiation value corresponding to the area range is obtained as the first infrared radiation value.

[0053] At the same time, according to the human body temperature T obj and ambient temperature T env The second infrared radiation value IR_2 corresponding to each person is calculated as:

[0054] IR_2=0.95(T obj -T env )+0.1(T obj -T env ) 3

[0055] Among them, IR_2 is the infrared radiation value, T obj is the measured body temperature, T env is the ambient temperature.

[0056] For example, in practical applications, the above-mentioned step of calculating IR_2 can be set at the wellhead of a coal mine. When each target person goes down the well, the infrared radiation and ambient temperature of the target person are collected, and the infrared radiation value and thermal radiation profile of each person are determined according to a preset algorithm.

[0057] For example, suppose we measure the temperature of person 1 to be 36.1°C and the ambient temperature is 25°C. Substituting into the above formula, we get the following result:

[0058] IR_2=0.95*(36.1-25)+0.1*(36.1-25)^3=8.52

[0059] Therefore, the infrared radiation value of this person is 8.52.

[0060] After the first infrared radiation value and the second infrared radiation value are calculated, a weighted sum is performed on the two to obtain a final infrared radiation value.

[0061] For example, suppose there is a group of 10 people, and the body temperature of each person fluctuates between 36° C. and 37° C. An infrared thermometer can be used to measure the forehead temperature of each person, and the body temperature data, infrared radiation value, and contour data are recorded in a table according to the personnel identification.

[0062] In the above manner, the infrared radiation value of an individual can be calculated based on the comprehensive consideration of the infrared pixel value, human body temperature and ambient temperature, and the associated storage can be performed to identify a specific target through the infrared radiation value.

[0063] In this solution, the infrared radiation value and thermal radiation profile of each staff member are collected in advance, and the above information is associated with the personnel identification and stored in the database to facilitate the subsequent matching of personnel information.

[0064] In step S130, in the underground environment, the calculated infrared radiation value and thermal radiation profile are matched with the infrared radiation value and thermal radiation profile in the database to determine the identity of the target person in the infrared image.

[0065] In one embodiment of the present application, the calculated infrared radiation value and thermal radiation profile are matched with the infrared radiation value and thermal radiation profile in the database to determine the identity of the target person in the infrared image, including:

[0066] Matching the calculated infrared radiation value with the infrared radiation value in the database to determine similar candidate identities;

[0067] The calculated thermal radiation profile is matched with the profile corresponding to the candidate identity to determine the identity of the target person in the infrared image.

[0068] During the data matching process, the infrared radiation values ​​can be matched first, and the first infrared radiation value calculated in real time can be compared with multiple second infrared radiation values ​​in the database, and multiple second infrared radiation values ​​within a certain range of the first infrared radiation value can be determined as the target infrared radiation value. Then, the infrared radiation profile obtained in real time can be compared with the infrared radiation profile corresponding to the target infrared radiation value to determine the matching infrared radiation profile and determine whether it is the infrared radiation profile of the target user.

[0069] Furthermore, since the values ​​in actual applications may have deviations, a deviation ratio is preset in this embodiment, which is used to determine a certain fluctuation range through the deviation ratio when matching the infrared radiation values. If the collected infrared radiation values ​​are within the range, it means that the match is successful. In this embodiment, when matching the infrared radiation profile, the area of ​​the infrared radiation profile can be calculated to determine the area ratio for evaluating the similarity; multiple feature points in the infrared radiation profile can be detected, the distances between the feature points can be calculated, and the ratios between the distances can be determined for evaluating the similarity. The above methods can be combined to make a judgment.

[0070] After data matching, the identity of the person in the target infrared image is determined based on the matching degree or other parameters, and the target person is located based on the acquisition position information of the infrared image.

[0071] In step S140, the position information corresponding to the target person is determined according to the position of the infrared device that collects the target person, thereby completing the positioning of the target person.

[0072] In one embodiment of the present application, based on the position of the infrared device that collects the target person's information, the position information corresponding to the target person is determined to complete the positioning of the target person, including: periodically detecting the position information corresponding to the target person through multiple infrared devices; and constructing a motion trajectory based on the detected position information.

[0073] In one embodiment of the present application, the infrared device periodically scans the target area according to a preset detection frequency. In each scan, the device emits infrared light and receives the reflected signal. The location information of the target person is calculated by parameters such as signal strength and time difference. Through trajectory construction, discrete location information points are connected into a continuous trajectory. According to parameters such as the moving speed and direction of the target person, the trajectory is further optimized and corrected. Unreasonable trajectory points are removed, such as abnormal situations such as sudden jumps and backtracking.

[0074] In one embodiment of the present application, constructing a motion trajectory based on detected position information includes: concatenating position information from different infrared devices; and completing missing position points by data interpolation to construct the motion trajectory.

[0075] In one embodiment of the present application, the location information data from different infrared devices are associated and matched according to the ID and timestamp of the target person, and duplicate data is removed to ensure that each location point is recorded only once.

[0076] Since the infrared devices may be arranged at certain intervals, the detected position information may not be continuous. The missing position points are supplemented by data interpolation to make the trajectory smoother. This can be done by linear interpolation, polynomial interpolation, etc., which will not be described here.

[0077] In one embodiment of the present application, the method further includes: further optimizing and correcting the trajectory according to parameters such as the moving speed and direction of the target person; and storing the optimized trajectory data in a database.

[0078] In one embodiment of the present application, the trajectory is further optimized and corrected according to parameters such as the target person's moving speed and direction, and unreasonable trajectory points are removed, such as sudden jumps, backtracking and other abnormal situations.

[0079] The optimized trajectory data is stored in the database for subsequent analysis and query. A visual interface is provided to display the trajectory in the form of maps, charts, etc. for easy viewing and analysis by users.

[0080] In one embodiment of the present application, the method further includes: displaying the trajectory data on a map; and issuing an alarm when it is detected that the trajectory data differs from a set trajectory by more than a set threshold.

[0081] In one embodiment of the present application, trajectory data including timestamp and corresponding geographic location coordinates are obtained from an infrared device or other data source. A map view object is created and parameters such as the initial map center and zoom level are set. The map view is embedded in the user interface of the application.

[0082] Traverse each coordinate point in the trajectory dataset. Use the API functions provided by the map service to add each coordinate point to a path or polyline object on the map. Update the map view in real time or periodically to reflect the latest status of the trajectory. Add user interaction functions such as zooming, panning, and clicking on trajectory points to view detailed information.

[0083] In this embodiment, one or more set tracks are predefined, which may be a fixed path, an area or a series of expected coordinate points. The data format of the set track is kept consistent with the track data for comparison.

[0084] Calculate the difference between the actual trajectory and the set trajectory. This can be achieved by calculating distance (such as Euclidean distance, Manhattan distance), time difference, path similarity and other indicators. For each timestamp or coordinate point, calculate the difference between the actual trajectory and the set trajectory. Set one or more difference thresholds based on application requirements. The threshold can be a fixed value or dynamically calculated (such as based on the standard deviation of historical data).

[0085] Check in real time or periodically whether the difference between the actual trajectory and the set trajectory exceeds the set threshold. If the difference is detected to exceed the threshold, the alarm mechanism is triggered. The alarm can be a warning message displayed through the user interface, an email or SMS notification, an audio or visual alarm, etc. Depending on the severity and type of the alarm, take appropriate action. This may include recording logs, sending notifications to relevant personnel, adjusting parameters of the monitoring system, etc.

[0086] Through the implementation of the above technical details, it is possible to display trajectory data on the map and issue an alarm when the difference between the detected trajectory and the set trajectory is greater than the set threshold. This helps to monitor and manage the movement behavior of the target person, detect abnormal situations in time and take corresponding measures.

[0087] In the technical solution of the present application, an infrared device is deployed underground in a coal mine; when the target personnel go down the mine, the infrared device is used to collect the infrared image and ambient temperature of the target personnel, and the infrared radiation value and thermal radiation profile of each person are determined, and the associated storage is in a database; in the underground environment, the calculated infrared radiation value and thermal radiation profile are matched with the infrared radiation value and thermal radiation profile in the database to determine the identity of the target personnel in the infrared image; according to the position of the infrared device that collects the target personnel, the position information corresponding to the target personnel is determined to complete the positioning of the target personnel. By deploying infrared devices, the infrared image and ambient temperature of the target personnel can be collected in real time, and then the infrared radiation value and thermal radiation profile can be determined, and matched with the information in the database to achieve high-precision identity recognition. At the same time, combined with the location information of the infrared device, the specific location of the target personnel can be accurately tracked, and the efficiency and safety of underground personnel management can be improved. This technology not only enhances the real-time monitoring capability, but also promotes the intelligence and automation of coal mine management.
