Specifically, if it is determined that there is a second repeater, it is determined whether there is an information blocking interval based on the second distance, the third distance, and the to-be-verified travel distance; If it is determined that there is no second repeater, it is determined whether there is an information blocking interval based on the second distance and the to-be-verified travel distance; An early warning module, connected to the information determination module, for obtaining the actual travel direction of the target object, and determining whether to give an early warning to the target object based on the to-be-verified travel direction and the actual travel direction.

[0031] Specifically, the target object in the embodiment of the present invention is a miner, and can also be an automatic handling machine, etc.

[0032] Specifically, the standard distance is the maximum distance that the repeater can achieve for information transmission in a preset normal mine environment. The mine distribution map consists of various roadways and numerous repeaters distributed in the mine. The positions of the roadways and repeaters can be determined through the mine distribution map. The advancing roadway is the roadway that the target object can choose to enter when reaching a roadway bifurcation during coal mining and transportation. The direction to be verified for advancement is the direction in which the advancing roadway is located. The distance to be verified for advancement is the distance from the entrance of the roadway that can be chosen to enter to the next roadway bifurcation. The distance threshold is the maximum distance at which the information reduced by the humidity and dust concentration environment in the mine can be normally transmitted by the repeater. The information blocking section is the roadway section in the distance to be verified for advancement in the advancing roadway where normal information transmission with the repeater cannot be carried out. The actual advancing direction is the direction of the advancing roadway selected by the target object. In this embodiment, when the target object reaches the bifurcation of the roadway during coal mining and transportation, it is determined whether there is a second repeater in each advancing roadway that can provide safety assurance for the target object. For each advancing roadway with a second repeater and without a second repeater, it is determined whether there is an information blocking section. When the target object selects a roadway to enter and the roadway has an information blocking section, a warning is given to the target object.

[0033] Specifically, by detecting the air humidity and dust concentration in the mine and calculating the signal transmission threshold, the communication distance can be adjusted according to the complex and changeable underground environmental conditions, improving the adaptability of the system. By comprehensively considering the position of the target object, the distribution of repeaters, and environmental parameters, the communication security risks of the target object in different roadways can be analyzed comprehensively and deeply. When potential communication risks are detected, the warning module can timely send a safety prompt to the target object, effectively reducing the potential safety hazards caused by communication blind spots, significantly improving the accuracy of safety monitoring, and enhancing the safety and reliability of mine operations.

[0034] Specifically, the threshold determination module includes: A first calculation unit for calculating the humidity deviation and concentration deviation based on the air humidity and the dust concentration and the corresponding humidity threshold and concentration threshold; A second calculation unit connected to the first calculation unit for calculating the information blocking ratio based on the humidity deviation, concentration deviation, and the corresponding humidity blocking coefficient and concentration blocking coefficient, and calculating the distance threshold based on the preset standard distance and the information blocking ratio.

[0035] Specifically, the preset standard distance is related to the repeaters used in the mine, usually 50 - 300 meters, and is 100 meters in this embodiment. The humidity blocking coefficient and the concentration blocking coefficient are the degrees of influence of different air humidities and dust concentrations in the mine on the information reception distance of the repeater respectively. In this embodiment, the humidity blocking coefficient is 20%, and the concentration blocking coefficient is 30%. The standard air humidity and the standard dust concentration are the air humidity and dust concentration when the information transmission distance of the repeater is the standard distance. Usually, the standard air humidity is 60% - 80%RH, and the standard dust concentration is 50 - 200mg / m³. In this embodiment, the standard air humidity is 80%RH, and the standard dust concentration is 100mg / m³. The humidity blocking coefficient and the concentration blocking coefficient are 20% and 30% respectively. In a specific implementation, the air humidity in the mine is 100%, the dust concentration is 200mg / m³, the concentration deviation is (200mg / m³ - 100mg / m³) / 100mg / m³ = 100%, the humidity deviation is (100% - 80%) / 80% = 25%. Calculate the humidity blocking ratio as 25%×20% = 5%, the concentration blocking ratio as 100%×30% = 30%, the information blocking ratio as 5% + 30% = 35%, then calculate the distance threshold as 100 meters×(1 - 0.35) = 65 meters.

[0036] Specifically, by correlating the air humidity and the dust concentration, calculating the information blocking ratio, the system can respond to the complex changes in the mine environment in real time, determine the signal transmission risks in the mine environment, and significantly improve the sensitivity and accuracy of the monitoring system.

[0037] Please continue to refer to Figure 2 , such as Figure 2 shown, which is a schematic structural diagram of the determination module of the embodiment of the present invention; Specifically, the determination module includes: a range determination unit for determining the information reception range of each repeater in the mine based on the mine distribution map according to the distance threshold; a determination unit connected to the range determination unit for determining whether each of the traveling roadways is within the information reception range of any repeater other than the first repeater, and determining whether there is the second repeater based on the determination result; a distance determination unit connected to the determination unit for determining the third distance within the information reception range of the second repeater when the determination result is that there is the second repeater.

[0038] Specifically, through the mine distribution map, the relationship between the traveling roadway at the bifurcation where the target object is located and the nearby repeaters can be determined. In a specific implementation, there are two traveling roadways for a certain target object when mining and transporting coal. At this time, the distance threshold of the repeaters in the mine environment is 65 meters. The to-be-verified traveling distance of one traveling roadway is 20 meters, and the distance from other repeaters except the first repeater exceeds 65 meters. The to-be-verified traveling distance of the other traveling roadway is 60 meters, and the distance from a repeater except the first repeater within a 10-meter section of this traveling roadway is less than 65 meters. Then, this repeater is determined as the second repeater.

[0039] Specifically, through the precise evaluation of the information reception range of the repeaters, accurately identify whether the traveling roadway is within the information reception range of the repeaters, calculate the specific distance of the roadway within the information reception range of the second repeater, provide more accurate data support for information transmission and safety assessment, accurately identify the information transmission blind spots and potential risks, and provide more comprehensive and accurate technical guarantee for the safety of the target object.

[0040] Specifically, the determination unit includes: A range reception unit for receiving the information reception ranges of the determined repeaters; An identification unit, which is connected to the range reception unit, for determining whether each of the roadways is within the information reception range, and determining the existence of the second repeater when it is determined to be within the information reception range.

[0041] Specifically, by receiving the already determined information reception ranges, the actual coverage range of the repeaters can be accurately located, laying a data foundation for subsequent accurate identification. The identification unit accurately and quickly identifies whether there is a potential second repeater by comparing the roadway positions with the information reception ranges of the repeaters, providing more comprehensive protection for the safety of the target object.

[0042] Please continue to refer to Figure 3 , as Figure 3 shown, which is a schematic structural diagram of the information determination module according to an embodiment of the present invention; Specifically, the information determination module includes: A first determination unit for, when determining the existence of the second repeater, calculating a fourth distance based on the second distance and the third distance, and determining whether there is an information blocking interval based on the fourth distance and the to-be-verified traveling distance; A second determination unit for, when determining the non-existence of the second repeater, comparing the second distance with the to-be-verified traveling distance, and determining whether there is an information blocking interval based on the comparison result.

[0043] In the specific implementation process, the distance threshold of the mine repeater is 65 meters. There is a second repeater in a traveling roadway, and according to the first distance from it to the first repeater being 40 meters, and for every 8 meters it travels in this traveling roadway, the distance from it to the first repeater increases by 4 meters. Then the second distance of this traveling roadway is (65 - 40) / 5 × 8 = 40 meters, where 5 in the calculation formula represents the safety distance between adjacent repeaters. The third distance within the information transmission range of the second repeater in the traveling roadway is 10 meters. Then the calculated fourth distance is 10 meters plus 40 meters, which is 50 meters.

[0044] Specifically, through the precise identification of different information transmission scenarios and the determination of information blocking intervals, potential blind spots in the information transmission process can be accurately identified, effectively improving the judgment accuracy and efficiency of information blocking intervals, reducing the misjudgment rate. Through precise calculation and comparison, the system can real-time evaluate the information transmission risks of target objects in different roadways and positions, thereby enhancing the reliability of the mine safety monitoring system and ensuring the safety of target objects.

[0045] Specifically, the first determination unit includes: A calculation subunit, used to sum the second distance and the third distance to obtain the fourth distance; A comparison subunit, connected to the calculation subunit, used to compare the to-be-verified traveling distance with the fourth distance to obtain a comparison result; A determination subunit, connected to the comparison subunit, used to determine the existence of an information blocking interval when the to-be-verified traveling distance is greater than the fourth distance.

[0046] Specifically, when the to-be-verified traveling distance is less than or equal to the fourth distance, it is determined that there is no information blocking interval.

[0047] In the specific implementation process, the fourth distance of the traveling roadway is 50 meters, and the to-be-verified traveling distance is 60 meters. By comparing the to-be-verified traveling distance with the fourth distance, since the to-be-verified traveling distance is greater than the fourth distance, it is determined that there is an information blocking interval.

[0048] Specifically, by calculating the fourth distance and comparing the to-be-verified traveling distance, an objective basis is provided for the determination of the information blocking interval. When the to-be-verified traveling distance is greater than the fourth distance, the determination subunit can accurately identify the information blocking interval, effectively coping with the complex and changeable mine environment, providing more intelligent and reliable technical support for mine safety monitoring, and enhancing the risk identification ability of the mine safety monitoring system.

[0049] Specifically, the warning module includes: A direction acquisition unit, used to acquire the actual traveling direction of the target object in the roadway selected at the fork. A direction determination unit, which is connected to the direction acquisition unit and is used to determine the corresponding to-be-verified travel direction based on the actual travel direction; An early warning unit, which is connected to the direction determination unit and is used to give an early warning to the target object when an information blocking section is determined to exist in the roadway of the to-be-verified travel direction.

[0050] In the specific implementation process, there are two travel roadways for the target object at the fork. It is detected that there is no information blocking section in the travel roadway with the to-be-verified travel direction of southeast, and there is an information blocking section in the travel roadway with the to-be-verified travel direction of northeast. When the actual travel direction of the actual target object during travel is northeast, and there is an information blocking section in the travel roadway of northeast, then an early warning is given to the target object, warning that there is an information blocking section ahead, and alerting the target object to observe carefully when passing through or choose another travel roadway to pass.

[0051] Specifically, by capturing the actual selected path of the target object at the fork, the actual travel direction is accurately corresponded with the preset to-be-verified travel direction, quickly identifying whether the target object enters a potential information blocking section, ensuring high-precision tracking and accurate positioning of the travel route of the target object. When it is determined that there is an information blocking section in the actual entry direction, a targeted safety warning can be immediately triggered, effectively reducing potential safety hazards in mine operations.

[0052] Specifically, the travel determination module includes: A fork road determination unit, which is used to determine the corresponding to-be-verified travel direction of each travel roadway in front of it according to the mine distribution map and the position of the target object; A distance determination unit, which is used to determine the distance between each to-be-verified travel direction from the roadway fork to the next fork according to the mine distribution map to obtain the to-be-verified travel distance.

[0053] Specifically, the travel roadways are determined for the travel direction of the target object based on the position of the target object and the roadway distribution position of the mine distribution map. In the specific implementation, the two travel roadways at the fork where the target object is located in the mine distribution map are located in the southeast and northeast of the target object. Then the to-be-verified travel directions of the two travel roadways are southeast and northeast. In the mine distribution map, the distances from the two travel roadways to their respective other forks are 60 meters and 20 meters. Then the to-be-verified travel distances of the two travel roadways are 60 meters and 20 meters respectively.

[0054] Specifically, through the fork determination unit and the distance determination unit in the path determination module, the accurate identification of the traveling route of the target object and the distance measurement are realized. The fork determination unit can accurately judge all possible traveling directions in front of the target object according to the mine distribution map and the real-time position of the target object, while the distance determination unit can accurately calculate the distances in each traveling direction, providing a reliable data basis for the subsequent information blocking interval judgment and early warning mechanism, significantly improving the accuracy of the mine safety monitoring system and the timeliness of early warning, and effectively reducing the risk of mine accidents.

[0055] Specifically, the environmental detection module includes: The first detection unit is used to detect the air humidity through a humidity sensor; The second detection unit is used to detect the mine dust concentration through a dust concentration sensor.

[0056] Specifically, by using a humidity sensor and a dust sensor to detect the air humidity and the mine dust concentration in the mine where the target object conducts operations, the accurate assessment of the environment can be ensured.

[0057] Specifically, by detecting environmental parameters, data support for a more comprehensive safety assessment is provided, which helps to give early warnings in a timely manner and significantly improves the mine safety monitoring level.
