[0026] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0027] It should be noted that all actions of acquiring signals, information or data in the present disclosure are performed with authorization given by the owner of the corresponding device.

[0028] Figure 1 FIG. 1 is a flow chart showing a method for early warning of spontaneous combustion of a coal pile in a coal yard according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0029] In step S11, a three-dimensional thermal map of the coal pile in the coal yard is obtained; the three-dimensional thermal map includes coordinate information and temperature distribution information of the coal pile.

[0030] In a possible implementation, the coal yard may be a circular coal yard which adopts a closed design and is covered with a vault and an air membrane structure to reduce environmental pollution and coal loss. The circular layout can effectively utilize space and facilitate the operation of stacking and reclaiming equipment.

[0031] In step S12, the location information of the pile of coal with a risk of spontaneous combustion is determined based on the coordinate information and temperature distribution information in the three-dimensional thermal map.

[0032] In step S13, the warning information is pushed to the security center device; the warning information includes the location information of the stockpile with the risk of spontaneous combustion.

[0033] For example, the coordinate information may be point cloud data obtained by a three-dimensional scanning device, and the temperature distribution information may be temperature distribution information of a coal pile in a coal yard obtained by a thermal imaging device, generally in the form of a two-dimensional image. It should be noted that the risk of spontaneous combustion refers to a situation where the temperature of the pile is greater than a set temperature warning value.

[0034] In the above technical solution, a three-dimensional thermal map of the coal pile in the coal yard is obtained, and the three-dimensional thermal map includes the coordinate information and temperature distribution information of the coal pile. According to the coordinate information and temperature distribution information in the three-dimensional thermal map, the location information of the pile with the risk of spontaneous combustion in the coal pile is determined, and the early warning information is pushed to the security center equipment end, and the early warning information includes the location information of the pile with the risk of spontaneous combustion. Through the above technical solution, the temperature of the coal pile in the coal yard is monitored in real time, and a three-dimensional thermal map with coordinate information and temperature distribution information is formed. The location information of the pile with the risk of spontaneous combustion in the coal pile is determined through the three-dimensional thermal map. It can improve the timeliness and accuracy of the temperature detection of the coal pile, and avoid the safety hazards in the manual inspection process.

[0035] Figure 2 The flowchart of a method for early warning of spontaneous combustion of a coal pile in a coal yard is shown according to an exemplary embodiment. The step S11 of obtaining a three-dimensional thermal map of the coal pile in the coal yard includes the following steps: Step S111, obtaining a three-dimensional scanning image of the coal pile output by a three-dimensional scanning device.

[0036] Step S112, obtaining a thermal imaging image of the coal pile output by the thermal imaging device.

[0037] For example, the three-dimensional scanning device can be a three-dimensional laser scanner, a structured light scanner, a three-dimensional lidar, etc.; the thermal imaging device can be an infrared thermal imager, an infrared thermometer, a thermal imaging drone, etc.

[0038] Step S113, acquiring the three-dimensional thermal map by fusing the three-dimensional scanning image and the thermal imaging image.

[0039] It is understandable that since 3D scanning and thermal imaging are two independent processes, the data obtained also belong to two coordinate systems, so the two image data need to be aligned in the same coordinate system. The temperature values ​​in the 3D point cloud and thermal imaging image can be automatically matched through an image processing algorithm to achieve automatic alignment. For example, the image processing algorithm can be an ICP (Iterative Closest Point) algorithm. After the data alignment is completed, each temperature value in the thermal imaging data is mapped to the corresponding point in the 3D point cloud, and the image is visualized, such as using different colors to represent different temperature ranges, so as to intuitively display the temperature distribution on the 3D thermal map.

[0040] Figure 3 The present invention is a flow chart of a method for early warning of spontaneous combustion of a coal pile in a coal yard according to an exemplary embodiment. The step S12 of determining the position information of the pile with spontaneous combustion risk in the coal pile according to the coordinate information and temperature distribution information in the three-dimensional thermal map includes the following steps: Step S121 : dividing the space of the three-dimensional thermal map into a plurality of cubes of unit volume, each of which includes a first number of first point cloud data including temperature values.

[0041] For example, the model space of the three-dimensional heat map is divided into multiple cubes of 1 cubic meter in size, and each cube contains 10 point cloud data with temperature.

[0042] Step S122: determining the location information of the stockpile with the risk of spontaneous combustion according to each of the first point cloud data.

[0043] In one implementation, step S122 may include: (1) Obtaining coordinate points corresponding to the first point cloud data in the cube whose temperature value is higher than a preset temperature threshold; (2) When the number of the coordinate points is greater than a preset number, the position information corresponding to the cube is determined to be the position information of the pile of materials with a risk of spontaneous combustion.

[0044] For example, the temperature values ​​of 10 point cloud data in each cube are obtained in real time, and each temperature value is compared with a preset temperature threshold (for example, 30°C). When the number of coordinate points with temperature values ​​higher than the preset temperature threshold is greater than a preset number (for example, 4), it is determined that the coal pile at the location of the cube has a risk of spontaneous combustion.

[0045] In another implementation, step S122 may further include: (1) Obtain the average temperature value of each cube in the space of the three-dimensional thermal map; (2) determining a cube to be detected from the multiple cubes according to the average temperature value; the cube to be detected is a cube corresponding to a cube having an average temperature value greater than a preset temperature threshold; (3) The cube to be detected is detected, and when the spontaneous combustion warning condition is met, the position information corresponding to the cube to be detected is determined to be the position information of the pile with the risk of spontaneous combustion.

[0046] For example, the model space of the three-dimensional thermal map is divided into multiple cubes of 1 cubic meter in size. For example, a circular coal yard can be divided into 3400 cubes. The average temperature value of each cube is calculated to obtain 3400 temperature data. The cubes corresponding to the temperature values ​​greater than the preset temperature threshold among the 3400 cubes are determined as the cubes to be detected. The temperature values ​​of the set area (for example, 10 square meters) around the cubes to be detected are detected. If the detection finds that the temperature values ​​of the area are all higher than the preset temperature threshold and multiple adjacent areas are connected, it can be determined that the coal piles in the cube to be detected and the set area around it are at risk of spontaneous combustion.

[0047] In another implementation, step S122 may further include: (1) Obtain the historical average temperature value of each cube; (2) When the upward trend of the historical average temperature value within a set period meets the spontaneous combustion warning condition, the position information corresponding to the cube is determined as the position information of the pile with the risk of spontaneous combustion.

[0048] For example, the historical temperature of each cube is obtained to detect whether the temperature changes within a set period. For example, when the temperature value of a cube rises every day for three consecutive days, and the rising temperature value exceeds 5°C, it can be determined that the coal pile corresponding to the cube has a risk of spontaneous combustion.

[0049] Figure 4 FIG. 1 is a flow chart showing another method for early warning of spontaneous combustion of coal piles in a coal yard according to an exemplary embodiment. Figure 4 As shown, the step S12 of determining the location information of the pile with the risk of spontaneous combustion in the coal pile according to the coordinate information and the temperature distribution information in the three-dimensional thermal map includes the following steps: Step S123, dividing the space of the three-dimensional thermal map into N sector spaces; each of the sector spaces includes a second number of second point cloud data containing temperature values; Step S124, determining the maximum temperature in each sector space; Step S125, comparing the maximum temperature corresponding to each sector space with the maximum temperatures corresponding to the remaining N-1 sector spaces in sequence; Step S126, when the spontaneous combustion warning condition is met, determining that the position information corresponding to the sector-shaped space is the position information of the stockpile with the risk of spontaneous combustion.

[0050] For example, the model space of the three-dimensional thermal map is divided into regions according to the angle, each region is a 10° sector space, and each sector space contains about 80,000 point cloud data with temperature. The maximum temperature in each sector space is calculated to form 36 sector temperature data. The 36 sector temperature data are subjected to cyclic comparison detection, for example, region 1 is compared with the remaining 35 regions, region 2 is compared with the remaining 35 regions, and so on to complete 36 cycles of detection. When the spontaneous combustion warning conditions are met during the detection and comparison analysis process, the position information corresponding to the sector space is determined to be the position information of the pile with the risk of spontaneous combustion.

[0051] Figure 5 FIG. 1 is a flow chart showing another method for early warning of spontaneous combustion of a coal pile in a coal yard according to an exemplary embodiment. Figure 5 As shown, the method may include the following steps: Step S14, obtaining the storage time of the coal pile in the coal yard; Step S15, when the storage time reaches the preset allowable storage time, an early warning message is sent to the safety center equipment terminal of the coal yard.

[0052] For example, when the coal is transported to the coal yard for storage, the storage time is counted. When the storage time reaches the preset allowable storage time, an early warning message is sent to the security center to prompt the staff to take corresponding measures. Different types of coal correspond to different storage times.

[0053] In another possible implementation, a countdown method can be used for early warning. For example, when the coal is transported to the coal yard for storage, the storage time of the coal type is determined based on the coal type information, and the storage time is set as the countdown time. When the remaining countdown time is less than the preset value or the countdown returns to zero, an early warning message is sent to the security center.

[0054] In the above technical solution, a three-dimensional thermal map of the coal pile in the coal yard is obtained, and the three-dimensional thermal map includes the coordinate information and temperature distribution information of the coal pile. According to the coordinate information and temperature distribution information in the three-dimensional thermal map, the location information of the pile with the risk of spontaneous combustion in the coal pile is determined, and the early warning information is pushed to the security center equipment end, and the early warning information includes the location information of the pile with the risk of spontaneous combustion. Through the above technical solution, the temperature of the coal pile in the coal yard is monitored in real time, and a three-dimensional thermal map with coordinate information and temperature distribution information is formed. The location information of the pile with the risk of spontaneous combustion in the coal pile is determined through the three-dimensional thermal map. It can improve the timeliness and accuracy of the temperature detection of the coal pile, and avoid the safety hazards in the manual inspection process.
