Description

Technical Field

[0001] This application relates to the field of intelligent safety detection technology in the coal industry, and in particular to a method for generating underground alarm information based on an AI analysis platform. This application also relates to an underground alarm information generation device based on an AI analysis platform and an underground alarm information generation device based on an AI analysis platform. Background Art

[0002] During coal mining, the oxygen content within the mine is a crucial indicator for ensuring the safety of miners and the smooth operation of production. To achieve real-time and accurate monitoring of oxygen concentration within the mine, multiple highly sensitive oxygen detection sensors are typically deployed in key areas of the mine. These sensors continuously collect underground oxygen data, providing timely information on oxygen changes within the mine. This ensures rapid warnings when oxygen levels deteriorate, safeguarding both personnel and equipment safety.

[0003] However, due to technical limitations, environmental interference, or aging, some sensors may experience false alarms. These false alarms not only frequently trigger safety warning systems, leading to unnecessary evacuations and mining suspensions, but also severely impact the efficiency and economic benefits of coal production.

[0004] Therefore, how to effectively identify false alarms from sensors and improve the efficiency of coal production has become a technical problem that needs to be solved urgently. Summary of the Invention

[0005] In view of this, the embodiments of the present application provide a method, device and equipment for generating underground alarm information based on an AI analysis platform to solve the problem of being unable to effectively identify false alarms of sensors.

[0006] According to a first aspect of an embodiment of the present application, a method for generating underground alarm information based on an AI analysis platform is provided, including: obtaining a first oxygen concentration value collected by a first sensor in a mine; judging whether the first oxygen concentration value is within a standard oxygen concentration range, and obtaining a first judgment result; if the first judgment result indicates that the first oxygen concentration value is not within the standard oxygen concentration range, judging whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level, and obtaining a second judgment result; if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, generating a first alarm message for reflecting that the operating personnel need to immediately evacuate the mine; if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level, generating a second alarm message for reflecting that the mine needs to be inspected.

[0007] According to the second aspect of the embodiments of the present application, a device for generating underground warning information based on an AI analysis platform is provided, including: an acquisition module, configured to acquire a first oxygen concentration value collected by a first sensor in a mine; a first judgment module, configured to judge whether the first oxygen concentration value is within a standard oxygen concentration range to obtain a first judgment result; a second judgment module, configured to, if the first judgment result indicates that the first oxygen concentration value is not within the standard oxygen concentration range, judge whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level to obtain a second judgment result; a first generation module, configured to, if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, generate a first warning information for reflecting that the operating personnel need to immediately evacuate the mine; a second generation module, configured to, if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level, generate a second warning information for reflecting that the mine needs to be inspected.

[0008] According to the third aspect of the embodiments of the present application, a device for generating underground warning information based on an AI analysis platform is provided, including: at least one processor; and a memory communicatively connected to the at least one processor; wherein, the memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can: acquire a first oxygen concentration value collected by a first sensor in a mine; judge whether the first oxygen concentration value is within a standard oxygen concentration range to obtain a first judgment result; if the first judgment result indicates that the first oxygen concentration value is not within the standard oxygen concentration range, judge whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level to obtain a second judgment result; if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, generate a first warning information for reflecting that the operating personnel need to immediately evacuate the mine; if the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level, generate a second warning information for reflecting that the mine needs to be inspected.

[0009] At least one embodiment of this specification can achieve the following beneficial effects: When the oxygen concentration value collected by the sensor is not within the standard range, it is necessary to further evaluate whether the risk level corresponding to the oxygen concentration value reaches or exceeds the preset risk level. If the risk level corresponding to this concentration value is greater than or equal to the preset risk level, a first warning message is generated to prompt the operator to immediately evacuate the mine, thereby ensuring personnel safety; if the risk level corresponding to this concentration value is less than the preset risk level, a second warning message is generated to prompt that the mine needs to be inspected. Through this judgment mechanism, not only is the first warning message that prompts the operator to immediately evacuate triggered every time the oxygen concentration value is abnormal avoided, but also the possible false alarm phenomenon of the sensor can be effectively identified, so that unnecessary safety warnings and the frequency of coal mining interruption can be reduced, and thus the efficiency of coal production can be improved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of one or more embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first. Depending on the context, the word "if" as used herein may be interpreted as "when" or "while" or "in response to determining".

[0015] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the present application are all information and data that have been authorized by the user or fully authorized by all parties, and the collection, use, and processing of the relevant data need to comply with the relevant laws, regulations, and standards in the relevant region, and corresponding operation entrances are provided for the user to select authorization or rejection.

[0016] First, the noun terms involved in one or more embodiments of this specification are explained.

[0017] The AI analysis platform refers to a comprehensive software system or service platform built based on artificial intelligence technology, which can automatically collect, process, and analyze a large amount of data, mine the potential laws and values in the data, and assist users in making scientific decisions. This platform usually integrates various AI algorithms such as machine learning, deep learning, and natural language processing, and has functions such as data preprocessing, model training, real-time analysis, and visual display, and is widely used in fields such as industrial monitoring, risk assessment, intelligent prediction, and anomaly detection.

[0018] At present, during the process of coal production, when the sensor monitors that the oxygen concentration is abnormal, the system usually immediately issues an evacuation warning, requiring the operators to quickly evacuate the mine, thus ensuring the safety of personnel. However, due to factors such as the technical performance of the sensor itself, the complex and changeable environment of the mine, and the increase in the service time of the equipment, the sensor may produce false alarms during the actual operation process. Such false alarms will lead to frequent emergency evacuations and interruptions of mining operations, thus seriously affecting the mining efficiency of coal production.

[0019] The following will, in conjunction with the accompanying drawings, elaborate on the technical solutions provided by each embodiment of this specification.

[0020] Figure 1 It is a schematic flowchart of a method for generating underground warning information based on an AI analysis platform provided by an embodiment of this specification.

[0021] From a program perspective, the execution entity of the process can be a program running on a warning information generation device. It can be understood that this method can be executed by any device, equipment, platform, or device cluster with computing and processing capabilities.

[0022] As Figure 1 shown, this process can include the following steps.

[0023] Step 102: Obtain the first oxygen concentration value collected by the first sensor in the mine.

[0024] In the embodiments of this specification, the mine can be a coal mine for coal mining, the first sensor can be any one or more sensors installed in the coal mine for collecting the oxygen concentration in the mine, the first oxygen concentration value can be the real-time oxygen concentration value collected by the first sensor, or the first oxygen concentration value can also be the average oxygen concentration value collected by the first sensor within a period of time.

[0025] In the embodiments of this specification, the manner in which the analysis system based on the AI analysis platform obtains the first oxygen concentration value can include: First, the analysis system sends an oxygen concentration value acquisition instruction to the first sensor, and the first sensor responds to this acquisition instruction and sends the first oxygen concentration value to the analysis system. Or, the first sensor can also actively feedback the first oxygen concentration value to the analysis system according to a preset rule, where the preset rule can be that the first sensor continuously feedbacks the first oxygen concentration value to the analysis system in real time, or the preset rule can also be that the first sensor feedbacks the first oxygen concentration value to the analysis system at regular time intervals.

[0026] Step 104: Determine whether the first oxygen concentration value is within the standard oxygen concentration range to obtain a first determination result.

[0027] In the embodiments of this specification, the standard oxygen concentration range can be the safe range value of oxygen concentration summarized based on the actual production experience and long-term safety management data in the underground mine. The standard oxygen concentration range can reflect the safe fluctuation range of the oxygen concentration in the underground environment on the premise of ensuring the life safety of the operating personnel and maintaining the normal production of the coal mine. In practical applications, by comprehensively analyzing historical monitoring data, accident cases, and the specific working conditions of the mine, scientifically determining this standard oxygen concentration range can set a reasonable threshold for the sensor alarm system, thereby effectively preventing safety accidents caused by abnormal oxygen content, and at the same time avoiding the risk of unnecessary production interruption caused by overly conservative settings.

[0028] Step 106: If the first judgment result indicates that the first oxygen concentration value is not within the standard oxygen concentration range, then determine whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level to obtain a second judgment result.

[0029] In the embodiments of this specification, the first oxygen concentration value not being within the standard oxygen concentration range can be expressed as the first oxygen concentration value being less than or equal to the minimum value of the standard oxygen concentration range, which reflects the risk of oxygen deficiency in the mine; or the first oxygen concentration value being greater than or equal to the maximum value of the standard oxygen concentration range, which reflects the risk of oxygen enrichment in the mine.

[0030] In the embodiments of this specification, the risk level corresponding to the first oxygen concentration value can be understood as the safety risk level determined in two ways: The first way is the safety risk level evaluated based on the deviation degree between the first oxygen concentration value and the pre-set standard oxygen concentration range. When the first oxygen concentration value is farther away from the standard oxygen concentration range, the safety risk level is higher; The second way can also be to evaluate the credibility of the first oxygen concentration value, that is, to judge the reliability of this oxygen concentration value by combining the accuracy of the sensor, environmental interference, and data stability, so as to determine the corresponding safety risk level. In practical applications, the risk level corresponding to the first oxygen concentration value can also be evaluated by combining the safety risk levels evaluated by the first way and the second way, so as to more scientifically and reasonably reflect the safety status of the oxygen environment in the mine, and then timely and effective safety response measures can be taken.

[0031] In practical applications, the preset risk level can be the risk level indicating that it is necessary to organize the operating personnel to evacuate the mine immediately.

[0032] Step 108: If the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, then generate a first warning message for reflecting that the operating personnel need to evacuate the mine immediately.

[0033] Step 110: If the second judgment result indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level, generate a second warning message for reflecting that the mine needs to be inspected.

[0034] In the embodiments of the present specification, when the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, a first warning message can be generated to prompt the operating personnel to immediately evacuate from the mine; when the risk level corresponding to the first oxygen concentration value is less than the preset risk level, the first warning message may not be generated, but a second warning message is generated to prompt that the environment and equipment in the mine need to be safety-checked.

[0035] It should be understood that the order of some steps of the method described in one or more embodiments of the present specification can be mutually exchanged according to actual needs, or some of the steps can also be omitted or deleted.

[0036] Figure 1 In the method, when the oxygen concentration value reported by the sensor for detecting the oxygen concentration in the mine exceeds the standard oxygen concentration range, if the risk level evaluated based on this oxygen concentration value is lower than the preset risk level, the alarm of the sensor this time can be determined as a false alarm. In this case, there is no need to trigger the first-level warning message reflecting that the operating personnel need to immediately evacuate the mine, but only generate a second-level warning message prompting that the mine environment needs to be further inspected. Through this hierarchical warning mechanism, the number of emergency responses caused by false alarms of the sensor can be effectively reduced, thereby reducing the suspension of coal mining caused by false alarms, ensuring the continuity and safety of mine operations, and improving the coal mining efficiency.

[0037] Based on Figure 1 the method, the embodiments of the present specification also provide some specific implementation manners of this method, which will be described below.

[0038] In an optional embodiment of the present specification, the minimum value of the standard oxygen concentration range is a first threshold, and the maximum value of the standard oxygen concentration range is a second threshold; the generation of the first warning message for reflecting that the operating personnel need to immediately evacuate the mine may specifically include: if the first oxygen concentration value is less than or equal to the first threshold, generate the first warning message for reflecting that there is an oxygen deficiency risk in the mine; if the first oxygen concentration value is greater than or equal to the second threshold, generate the first warning message for reflecting that there is an oxygen enrichment risk in the mine.

[0039] In the embodiments of this specification, an anoxic environment is usually accompanied by physiological reactions such as a decrease in gas concentration and difficulty in breathing, which pose a direct threat to the health of personnel. Although an oxygen-rich environment does not immediately cause asphyxia or difficulty in breathing, its potential fire and explosion risks still require high vigilance. Therefore, in order to ensure that operators and safety managers can quickly understand the meaning of warning information and take effective countermeasures, the first warning information for anoxic risks and the first warning information for oxygen-rich risks can usually be set in different display forms. In practical applications, the first warning information for anoxic risks and the first warning information for oxygen-rich risks can be distinguished and displayed not only by the different text contents shown and the voice broadcast contents, but also by different visual effects. For example, the first warning information for anoxic risks can be presented through animations or images containing physiological reactions, such as a picture of a person having difficulty breathing, vividly demonstrating the physiological hazards brought about by anoxia, thereby enhancing the visual impact. The display screen of the first warning information for oxygen-rich risks can convey information through pictures of potential hazards such as flames and explosions, for example, dynamic effects containing explosion or fire scenes, to remind personnel of the potential dangers that may be brought about by excessive oxygen concentration, etc.

[0040] In the embodiments of this specification, when the first oxygen concentration value detected in the mine is less than or equal to a preset first threshold, it indicates that the oxygen content in the mine has fallen below the safe standard range, and there is a potential risk of anoxia. At this time, the system will generate the first warning information for anoxic risks, prompting operators and managers that there may be risks in the mine environment caused by insufficient oxygen, and that corresponding safety measures need to be taken in a timely manner to prevent anoxia from causing personnel asphyxia or other safety accidents. On the contrary, when the first oxygen concentration value is greater than or equal to a preset second threshold, it indicates that the oxygen concentration in the mine has exceeded the upper limit of the safe standard, and there is a potential risk of oxygen enrichment. Therefore, the system will also generate the first warning information for oxygen-rich risks, reminding relevant personnel to pay attention to the oxygen-rich state in the mine and take effective preventive measures to ensure operation safety. By comparing and judging the first oxygen concentration value with the two key thresholds, the system can timely identify different types of oxygen abnormal conditions in the mine and issue corresponding safety warnings, thereby effectively ensuring the life safety of mine operators and the overall operation safety of the mine.

[0041] Generally, there are multiple sensors installed in the mine for detecting oxygen concentration. When the first oxygen concentration value collected by the first sensor is not within the standard oxygen concentration range, the oxygen concentration values collected by other sensors can be combined to evaluate whether the risk degree corresponding to the first oxygen concentration value is greater than or equal to a preset risk degree.

[0042] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level may specifically include: obtaining the location information of the first sensor; based on the location information, obtaining a second oxygen concentration value collected by a second sensor adjacent to the first sensor; and based on the second oxygen concentration value, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0043] In the embodiments of the present specification, when installing sensors for detecting oxygen concentration in a mine, the installation location information and sensor number information of each sensor can be recorded in advance, and the corresponding relationship between the installation location information of the sensor and the sensor number information can be established in advance. The transmission information containing the oxygen concentration value sent by the sensor to the analysis system can carry the sensor number information of the sensor.

[0044] Optionally, obtaining the location information of the first sensor may include parsing the sensor number information of the sensor that sent the first oxygen concentration value from the received information where the first oxygen concentration value is located, and according to the sensor number information, querying the corresponding relationship between the installation location information of the sensor and the sensor number information to obtain the location information of the sensor.

[0045] In the embodiments of the present specification, after obtaining the location information of the first sensor, the second sensor adjacent to the first sensor can be determined according to the installation location information of each sensor stored in advance, and the second oxygen concentration value collected by the second sensor can be obtained. Based on the second oxygen concentration value, the reliability of the first oxygen concentration value can be evaluated, and thereby it can be determined whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0046] The second sensor adjacent to the first sensor can be a sensor located at the upwind of the first sensor or a sensor located at the downwind of the first sensor. Therefore, for second sensors at different positions, different judgment methods are adopted.

[0047] In the scenario where the second sensor is located at the upwind of the first sensor and the first oxygen concentration value collected by the first sensor is less than or equal to the first threshold, that is, the risk reflected by the first oxygen concentration value is an oxygen deficiency risk.

[0048] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level based on the second oxygen concentration value specifically includes: determining whether the second oxygen concentration value is within the standard oxygen concentration range to obtain a third determination result; if the third determination result indicates that the second oxygen concentration value is within the standard oxygen concentration range, then based on the oxygen concentration difference between the second oxygen concentration value and the first oxygen concentration value, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level. That the risk level corresponding to the first oxygen concentration value is less than the preset risk level may specifically include: if the oxygen concentration difference is greater than or equal to a third threshold, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0049] Based on the laws of natural air kinetics, it can be known that the oxygen concentration in a mine will gradually decrease along the direction of the wind, that is, the oxygen concentration at the upwind position is higher than that at the downwind position, and the decrease amplitude of the oxygen concentration from the upwind position to the downwind position should be less than a preset threshold.

[0050] In the embodiments of this specification, the second oxygen concentration value collected by the second sensor is obtained, and it is determined whether the second oxygen concentration value is within the standard oxygen concentration range. If the second oxygen concentration value is not within the standard oxygen concentration range, specifically, if the second oxygen concentration value is less than or equal to the first threshold. In other words, if it is inferred from the second oxygen concentration value that there is an oxygen deficiency risk in the mine, it can be determined that the credibility of the evaluation result that there is an oxygen deficiency risk in the mine inferred based on the first oxygen concentration value is relatively high, that is, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0051] If the second oxygen concentration value is within the standard oxygen concentration range, at this time, it is not inferred from the second oxygen concentration value that there is an oxygen deficiency risk in the mine, but it is inferred from the first oxygen concentration value that there is an oxygen deficiency risk in the mine. Therefore, in order to further evaluate the credibility of the evaluation result that there is an oxygen deficiency risk in the mine inferred based on the first oxygen concentration value, it can be evaluated by determining whether the oxygen concentration difference between the second oxygen concentration value and the first oxygen concentration value, that is, the oxygen concentration decrease amplitude, conforms to the laws of natural air kinetics.

[0052] If the concentration difference between the second oxygen concentration value and the first oxygen concentration value is less than the third threshold, that is, the oxygen concentration decrease amplitude conforms to the laws of natural air kinetics, it can be indicated that the credibility of the evaluation result that there is an oxygen deficiency risk in the mine inferred based on the first oxygen concentration value is relatively high, that is, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0053] If the concentration difference between the second oxygen concentration value and the first oxygen concentration value is greater than or equal to the third threshold, that is, the decline rate of the oxygen concentration does not conform to the law of natural air kinetics, it can indicate that the credibility of the evaluation result that there is an oxygen hypoxia risk in the mine inferred from the first oxygen concentration value is relatively low, that is, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0054] In the embodiments of this specification, the second oxygen concentration value collected by the second sensor located at the upwind of the first sensor can be used to evaluate the credibility of the hypoxia risk inferred based on the first oxygen concentration value, thereby effectively reducing the false alarm probability of the hypoxia risk caused by the oxygen concentration value collected by the first sensor.

[0055] However, the first oxygen concentration value collected by the first sensor may also be affected by the installation location environment. In some special scenarios, the decline rate of the oxygen concentration does not conform to the law of natural air kinetics. Although this violates the law of natural phenomena, it does not necessarily mean that the credibility of the hypoxia risk inferred based on the first oxygen concentration value is necessarily low. In other words, despite this abnormal phenomenon, due to the interference of the installation location environment or special conditions, the first oxygen concentration value may still be able to accurately reflect the actual risk situation. Therefore, simply negating the effectiveness of the risk assessment corresponding to the first oxygen concentration value based on this abnormal phenomenon may lead to the risk of missed alarms, which may endanger the safety of personnel and equipment.

[0056] Optionally, if the oxygen concentration difference is greater than or equal to the third threshold, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level. Specifically, it may include: based on the position information of the first sensor, obtaining the spatial environment corresponding to the position information; judging whether the ventilation condition of the spatial environment meets the preset requirements; if the ventilation condition of the spatial environment information meets the preset requirements, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level; if the ventilation condition of the spatial environment information does not meet the preset requirements, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0057] In the embodiments of this specification, the method for obtaining the spatial environment corresponding to the position information may include querying from a pre-established digital twin system the spatial environment corresponding to the position information. Among them, the digital twin system is a highly simulated virtual environment constructed based on the real physical environment in the mine. By collecting and synchronizing various data in the mine in real time, dynamic simulation and monitoring of the mine operation status, environmental changes, and equipment conditions are realized. That the ventilation condition of the spatial environment meets the preset requirements can be understood as that the first sensor is installed in a relatively wide and straight main road environment in the mine; that the ventilation condition of the spatial environment does not meet the preset requirements can be understood as that the first sensor is installed in a small branch road environment with a large curvature or many turns in the mine.

[0058] Figure 2 It is a schematic diagram of the environment of the first installation environment for installing the first sensor provided in the embodiments of this specification.

[0059] In the embodiments of this specification, as Figure 2 shown, the first sensor 201 is installed in a small branch road environment with a large curvature. Since the air flow rate in this branch road environment is lower than that in the main road environment, the probability of a lower oxygen concentration in this branch road environment is relatively high. In this case, even if the decrease in the oxygen concentration from the installation position of the second sensor 202 to the installation position of the first sensor 201 does not conform to the law of natural air kinetics, this situation is reasonable and practical. In other words, it is normal that the concentration difference between the second oxygen concentration value and the first oxygen concentration value is greater than or equal to the third threshold, which indicates that the accuracy and credibility of the first oxygen concentration value are relatively high. Therefore, it can be inferred that there is a relatively high risk of hypoxia in the surrounding environment of the first sensor 201, and the risk level corresponding to its first oxygen concentration value is likely to be greater than or equal to the preset risk level, so as to prompt attention to and timely response to the hypoxia risk in this environment.

[0060] In the embodiments of this specification, by further observing the installation environment condition of the first sensor, after evaluating the credibility of the hypoxia risk inferred from the first oxygen concentration value based on the second oxygen concentration value, a more detailed risk assessment can be further carried out. This further assessment can effectively reduce the possibility of missed reporting of the hypoxia risk caused by the oxygen concentration value collected by the first sensor, and improve the safety of personnel and equipment.

[0061] In the scenario where the second sensor is located upwind of the first sensor, and the first oxygen concentration value collected by the first sensor is greater than or equal to the second threshold, that is, the risk reflected by the first oxygen concentration value is an oxygen-rich risk.

[0062] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level based on the second oxygen concentration value may specifically include: determining whether the second oxygen concentration value is within the standard oxygen concentration range to obtain a fifth determination result; the risk level corresponding to the first oxygen concentration value being less than the preset risk level may specifically include: if the fifth determination result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0063] In the embodiments of the present specification, if the second sensor is installed at the upwind of the first sensor, according to the law of natural air flow, the second oxygen concentration value should be higher than the first oxygen concentration value. However, if it is determined that the second oxygen concentration value is within the standard oxygen concentration range, but the first oxygen concentration value is greater than or equal to the maximum value (the second threshold) of the standard oxygen concentration range, that is, at this time the second oxygen concentration value is instead lower than the first oxygen concentration value, then this situation obviously violates the law of natural phenomena. Therefore, this unexpected result indicates that there may be a risk of data error between the second oxygen concentration value and the first oxygen concentration value. In this case, the credibility of the oxygen enrichment risk inferred based on the first oxygen concentration value is significantly reduced, so it can be speculated that the risk level corresponding to the first oxygen concentration value is likely to be lower than the preset risk level.

[0064] In the embodiments of the present specification, the second oxygen concentration value collected by the second sensor located at the upwind of the first sensor can be used to evaluate the credibility of the oxygen enrichment risk inferred based on the first oxygen concentration value, thereby effectively reducing the false alarm probability of the oxygen enrichment risk caused by the oxygen concentration value collected by the first sensor.

[0065] However, the first oxygen concentration value collected by the first sensor may also be affected by external environmental factors. In some special scenarios, the situation where the second oxygen concentration value is lower than the first oxygen concentration value occurs. Although this violates the law of natural phenomena, it does not necessarily mean that the credibility of the oxygen enrichment risk inferred based on the first oxygen concentration value must be low. In other words, although this phenomenon is abnormal, due to the interference of the external environment or special conditions, the first oxygen concentration value may still accurately reflect the actual risk situation. Therefore, simply negating the effectiveness of the risk assessment corresponding to the first oxygen concentration value based on this abnormal phenomenon may lead to the risk of missed alarms, thereby endangering the safety of personnel and equipment.

[0066] Optionally, if the fifth judgment result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level. Specifically, it may include: obtaining the surrounding environment information of the first sensor based on the position information of the first sensor; determining whether there is an oxygenation device in the environment corresponding to the surrounding environment information; if there is no oxygenation device in the environment corresponding to the surrounding environment information, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level; if there is an oxygenation device in the environment corresponding to the surrounding environment information, it means that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level. In practical applications, the surrounding environment information of the first sensor can be queried through a pre-established digital twin system. The explanation of the digital twin system can refer to the above content and will not be elaborated here.

[0068] In the embodiments of this specification, as Figure 3 shown, an oxygenation device 303 is equipped in the surrounding environment of the first sensor 301, and this oxygenation device 303 can significantly increase the oxygen concentration in the surrounding environment of the first sensor 301. Therefore, the oxygen concentration detected by the first sensor 301 is affected not only by the oxygen content of the air introduced into the external environment but also by the additional oxygen generated by the oxygenation device 303. In this case, even if the second oxygen concentration value collected by the second sensor 302 is lower than the first oxygen concentration value collected by the first sensor 301, this phenomenon is reasonable and in line with the actual situation. In other words, the situation where the second oxygen concentration is lower than the first oxygen concentration is a normal phenomenon, which indicates that the accuracy and credibility of the first oxygen concentration value are relatively high. Therefore, it can be inferred that there is a relatively high risk of oxygen enrichment in the surrounding environment of the first sensor 301, and the risk level corresponding to its first oxygen concentration value is probably greater than or equal to the preset risk level, so as to prompt attention to and timely response to the oxygen enrichment risk in this environment.

[0069] In the embodiments of this specification, by further observing the environmental conditions around the first sensor, after evaluating the credibility of the oxygen enrichment risk inferred from the first oxygen concentration value based on the second oxygen concentration value, a more detailed risk assessment can be further carried out. This further assessment can effectively reduce the possibility of missed reporting of the oxygen enrichment risk caused by the oxygen concentration value collected by the first sensor and improve the safety of personnel and equipment.

[0070] In the scenario where the second sensor is located in the downwind direction of the first sensor, and the first oxygen concentration value collected by the first sensor is less than or equal to the first threshold, that is, the risk reflected by the first oxygen concentration value is an oxygen deficiency risk.

[0071] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level based on the second oxygen concentration value may specifically include: determining whether the second oxygen concentration value is within the standard oxygen concentration range to obtain a sixth determination result; the risk level corresponding to the first oxygen concentration value being less than the preset risk level may specifically include: if the sixth determination result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0072] In the embodiments of this specification, if the second sensor is installed in the downwind direction of the first sensor, according to the laws of natural air kinetics, the second oxygen concentration value should be lower than the first oxygen concentration value. However, if it is determined that the second oxygen concentration value is within the standard oxygen concentration range, but the first oxygen concentration value is less than or equal to the minimum value (the first threshold) of the standard oxygen concentration range, that is, at this time the second oxygen concentration value is actually higher than the first oxygen concentration value, then this situation obviously violates the laws of natural phenomena. Therefore, this unexpected result indicates that there may be a risk of data error between the second oxygen concentration value and the first oxygen concentration value. In this case, the credibility of the oxygen deficiency risk inferred based on the first oxygen concentration value is significantly reduced, so it can be speculated that the risk level corresponding to the first oxygen concentration value is very likely to be lower than the preset risk level.

[0073] In the embodiments of this specification, the second oxygen concentration value collected by the second sensor located in the downwind direction of the first sensor can be used to evaluate the credibility of the oxygen deficiency risk inferred based on the first oxygen concentration value, thereby effectively reducing the false alarm probability of the oxygen deficiency risk caused by the oxygen concentration value collected by the first sensor.

[0074] However, the first oxygen concentration value collected by the first sensor may also be affected by the installation location environment. In some special scenarios, the situation where the second oxygen concentration value is higher than the first oxygen concentration value may occur. Although this violates the laws of natural phenomena, it does not necessarily mean that the credibility of the oxygen deficiency risk inferred based on the first oxygen concentration value must be low. In other words, although this phenomenon is abnormal, due to the interference of the external environment or special conditions, the first oxygen concentration value may still be able to accurately reflect the actual risk situation. Therefore, simply denying the effectiveness of the risk assessment corresponding to the first oxygen concentration value based on this abnormal phenomenon may lead to the risk of missed alarms, which may further endanger the safety of personnel and equipment.

[0075] Optionally, if the sixth judgment result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level. Specifically, it may include: based on the position information of the first sensor, obtaining the spatial environment corresponding to the position information; judging whether the ventilation condition of the spatial environment meets the preset requirements; if the ventilation condition of the spatial environment meets the preset requirements, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level; if the ventilation condition of the spatial environment information does not meet the preset requirements, it means that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0076] In the embodiments of this specification, the method for obtaining the spatial environment corresponding to the position information may include querying the spatial environment corresponding to the position information from a pre-established digital twin system. That the ventilation condition of the spatial environment meets the preset requirements can be understood as that the first sensor is installed in a relatively wide and straight main road environment in the mine; that the ventilation condition of the spatial environment does not meet the preset requirements can be understood as that the first sensor is installed in a small branch road environment in the mine with a large curvature or many turns.

[0077] Figure 4 It is a schematic diagram of the environment of the third installation environment for installing the first sensor provided in the embodiments of this specification.

[0078] In the embodiments of this specification, as Figure 4 shown, the first sensor 401 is installed in a branch road environment with a large curvature. Since the air flow in this branch road environment is lower than that in the main road environment, the probability of causing a lower oxygen concentration in this branch road environment is relatively high. In this case, even if the second oxygen concentration value collected by the second sensor 402 is higher than the first oxygen concentration value collected by the first sensor 401, this phenomenon is reasonable and in line with the actual situation. In other words, the situation where the second oxygen concentration is higher than the first oxygen concentration is a normal phenomenon, which indicates that the accuracy and credibility of the first oxygen concentration value are relatively high. Therefore, it can be inferred that there is a relatively high risk of hypoxia in the surrounding environment of the first sensor 401, and the risk level corresponding to its first oxygen concentration value is probably greater than or equal to the preset risk level, so as to prompt attention to and timely response to the hypoxia risk in this environment.

[0079] In the embodiments of this specification, by further observing the installation environment condition of the first sensor, after evaluating the credibility of the hypoxia risk inferred from the first oxygen concentration value based on the second oxygen concentration value, a more detailed risk assessment can be further carried out. This further assessment can effectively reduce the possibility of the hypoxia risk caused by the oxygen concentration value collected by the first sensor being missed, and improve the safety of personnel and equipment.

[0080] When the second sensor is located in the downwind direction of the first sensor, and the first oxygen concentration value collected by the first sensor is greater than or equal to the second threshold, that is, the risk reflected by the first oxygen concentration value is an oxygen-rich risk scenario.

[0081] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to a preset risk level based on the second oxygen concentration value may specifically include: determining whether the second oxygen concentration value is within the standard oxygen concentration range to obtain a seventh determination result; if the seventh determination result indicates that the second oxygen concentration value is within the standard oxygen concentration range, then based on the oxygen concentration difference between the first oxygen concentration value and the second oxygen concentration value, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level; the risk level corresponding to the first oxygen concentration value being less than the preset risk level specifically includes: if the oxygen concentration difference is greater than or equal to the fourth threshold, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0082] In the embodiments of this specification, obtain the second oxygen concentration value collected by the second sensor, and determine whether the second oxygen concentration value is within the standard oxygen concentration range. If the second oxygen concentration value is not within the standard oxygen concentration range, specifically, if the second oxygen concentration value is greater than or equal to the second threshold. In other words, if it is inferred from the second oxygen concentration value that there is an oxygen-rich risk in the mine, it can be determined that the credibility of the evaluation result that there is an oxygen-rich risk in the mine inferred based on the first oxygen concentration value is relatively high, that is, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0083] If the second oxygen concentration value is within the standard oxygen concentration range, at this time, it is not inferred from the second oxygen concentration value that there is an oxygen-rich risk in the mine, but it is inferred from the first oxygen concentration value that there is an oxygen-rich risk in the mine. Therefore, in order to further evaluate the credibility of the evaluation result that there is an oxygen-rich risk in the mine inferred based on the first oxygen concentration value, it can be evaluated by determining whether the oxygen concentration difference between the first oxygen concentration value and the second oxygen concentration value, that is, the oxygen concentration decrease amplitude, conforms to the law of natural air flow.

[0084] If the concentration difference between the first oxygen concentration value and the second oxygen concentration value is less than the fourth threshold, that is, the oxygen concentration decrease amplitude conforms to the law of natural air flow, it can be indicated that the credibility of the evaluation result that there is an oxygen-rich risk in the mine inferred based on the first oxygen concentration value is relatively high, that is, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level.

[0085] If the concentration difference between the first oxygen concentration value and the second oxygen concentration value is greater than or equal to the fourth threshold, that is, the decrease in oxygen concentration does not conform to the law of natural air kinetics, it can indicate that the credibility of the evaluation result that there is an oxygen enrichment risk in the mine inferred from the first oxygen concentration value is relatively low, that is, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0086] In the embodiments of this specification, the second oxygen concentration value collected by the second sensor located at the downwind of the first sensor can be used to evaluate the credibility of the oxygen enrichment risk inferred based on the first oxygen concentration value, thereby effectively reducing the false alarm probability of the oxygen enrichment risk caused by the oxygen concentration value collected by the first sensor.

[0087] However, the first oxygen concentration value collected by the first sensor may also be affected by external environmental factors. In some special scenarios, the situation where the decrease in oxygen concentration does not conform to the law of natural air kinetics occurs. Although this violates the law of natural phenomena, it does not necessarily mean that the credibility of the oxygen enrichment risk inferred based on the first oxygen concentration value is necessarily low. In other words, although this phenomenon is abnormal, due to the interference of the installation location environment or special conditions, the first oxygen concentration value may still be able to accurately reflect the actual risk situation. Therefore, simply negating the effectiveness of the risk assessment corresponding to the first oxygen concentration value based on this abnormal phenomenon may lead to the risk of missed alarms, which in turn endangers the safety of personnel and equipment.

[0088] Optionally, if the oxygen concentration difference is greater than or equal to the fourth threshold, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level. Specifically, it may include: obtaining the surrounding environment information of the first sensor based on the position information of the first sensor; determining whether there is an oxygen-increasing device in the environment corresponding to the surrounding environment information; if there is no oxygen-increasing device in the environment corresponding to the surrounding environment information, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level; if there is an oxygen-increasing device in the environment corresponding to the surrounding environment information, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level. In practical applications, the surrounding environment information of the first sensor can be queried through a pre-established digital twin system. The explanation of the digital twin system can refer to the above content and will not be elaborated here.

[0089] Figure 5 It is a schematic diagram of the environment of the fourth installation environment for installing the first sensor provided in the embodiments of this specification.

[0090] In the embodiments of this specification, such as Figure 5As shown in the figure, an oxygenation device 503 is equipped in the surrounding environment of the first sensor 501, and the oxygenation device 503 can significantly increase the oxygen concentration in the surrounding environment of the first sensor 501. Therefore, the oxygen concentration detected by the first sensor 501 is affected not only by the oxygen content of the introduced air in the external environment, but also by the additional oxygen generated by the oxygenation device 503. In this case, even if the decrease in the oxygen concentration from the installation position of the first sensor 501 to the installation position of the second sensor 502 does not conform to the law of natural air kinetics, this situation is reasonable and practical. In other words, the concentration difference between the first oxygen concentration value and the second oxygen concentration value being greater than or equal to the fourth threshold is a normal phenomenon, which indicates that the accuracy and credibility of the first oxygen concentration value are relatively high. Therefore, it can be inferred that there is a relatively high risk of oxygen enrichment in the surrounding environment of the first sensor 501, and the risk level corresponding to the first oxygen concentration value is very likely to be greater than or equal to the preset risk level, so as to prompt attention to and timely response to the oxygen enrichment risk in this environment.

[0091] In the embodiments of this specification, by further observing the environmental conditions around the first sensor, after evaluating the credibility of the oxygen enrichment risk inferred from the first oxygen concentration value based on the second oxygen concentration value, a more detailed risk assessment can be further carried out. This further assessment can effectively reduce the possibility of the oxygen enrichment risk caused by the oxygen concentration value collected by the first sensor being missed, and improve the safety of personnel and equipment.

[0092] In the embodiments of this specification, the reliability and accuracy of the first oxygen concentration value can also be comprehensively evaluated by detecting various environmental parameters in the mine from the perspective of whether the environmental parameters will affect the sensitivity of the sensor.

[0093] Optionally, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level may specifically include: obtaining the environmental parameter values collected by the sensors installed in the mine for detecting environmental parameters; based on the environmental parameter values, determining whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level; that the risk level corresponding to the first oxygen concentration value is less than the preset risk level may specifically include: if the environmental parameter values are not within the range of standard environmental parameter values, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0094] Under normal circumstances, only when the environmental parameters in the mine meet the applicable conditions for the design and operation of the sensors, the oxygen concentration data collected by the first sensor can be considered to have relatively high credibility. Otherwise, if the environmental parameters are abnormal, it may cause errors in the measurement data of the sensor, and the credibility of the oxygen concentration data collected by the first sensor is relatively low.

[0095] In the embodiments of this specification, the environmental parameters may include environmental temperature parameters, environmental humidity parameters, etc. The standard environmental parameter value range may be the normal operating environmental parameter range of the first sensor. When the environmental parameter value is within the standard environmental parameter range, that is, when the environmental parameters around the first sensor meet the normal operating conditions of the first sensor, environmental factors will not interfere with the sensitivity and detection accuracy of the sensor, thus making the first oxygen concentration value highly credible. In this case, if the first oxygen concentration value is not within the standard oxygen concentration range, it may indicate that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level. On the contrary, if the environmental parameter value is not within the standard environmental parameter range, that is, the environment where the first sensor is located does not meet its normal operating conditions, environmental factors are very likely to interfere with the sensitivity and detection accuracy of the sensor, resulting in errors in the detection of the first sensor, thereby reducing the credibility of the first oxygen concentration value. At this time, if the first oxygen concentration value is not within the standard oxygen concentration range, it may indicate that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0096] In the embodiments of this specification, by combining the environmental parameter values in the mine, the credibility of the first oxygen concentration value is scientifically evaluated, thereby improving the accuracy and effectiveness of overall risk identification and effectively reducing the false alarm probability caused by the oxygen concentration value collected by the first sensor.

[0097] However, due to the unique detection characteristics of different sensors, there are often differences in the installation quantity and specific installation positions between the sensors for monitoring environmental parameters and the sensors for measuring oxygen concentration in the mine. Because of this, in some special or complex mine environmental scenarios, the data collected by the environmental parameter sensors may not accurately reflect the actual environmental conditions around the oxygen sensors. Thus, there may be a certain deviation between the values obtained by the environmental parameter sensors and the environmental parameters of the actual environment where the oxygen sensors are located, thereby affecting the evaluation and analysis of the first oxygen concentration value.

[0098] Optionally, if the environmental parameter value is not within the standard environmental parameter value range, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level, which may specifically include: obtaining an environmental picture image corresponding to the target installation position of the environmental parameter sensor; determining whether there is a safety risk event in the environmental picture image, where the safety risk event includes an event that causes a local change in the environmental parameter value at the target installation position; if there is a safety risk event in the environmental picture image, it indicates that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level; if there is no safety risk event in the environmental picture image, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0099] In the embodiments of this specification, the environmental scene image can be an image queried based on the digital twin system. For the explanation of the digital twin system, reference can be made to the above content, which will not be elaborated here.

[0100] In the embodiments of this specification, the installation positions of the first sensor and the environmental sensor can be different. In special scenarios, there may be differences in the environmental conditions around the first sensor and the environmental sensor.

[0101] Figure 6 It is a schematic diagram of the environmental scene image corresponding to the installation position of the environmental parameter sensor provided in the embodiments of this specification.

[0102] In the embodiments of this specification, as Figure 6 shown, there is a safety risk event that operators use a heating facility 603 for illegal heating around the environmental parameter sensor 602. For example, operators illegally bring a heating device into the mine for illegal heating. This event will cause the environmental temperature around the environmental parameter sensor 602 to rise rapidly, and the rising temperature will simultaneously cause a large amount of water vapor to be generated, which will also cause the environmental humidity to rise rapidly. Eventually, the temperature and humidity data measured by the environmental parameter sensor 602 may exceed the range of standard environmental parameters. However, it should be noted that the temperature and humidity changes caused by the heating facility 603 are limited to the local environment range of the environmental parameter sensor 602 and do not cause significant changes in the overall environmental temperature and humidity of the mine. Therefore, the data collected by the environmental parameter sensor 602 may not be able to accurately reflect the actual environmental conditions around the first sensor 601. In this case, although the parameter value measured by the environmental parameter sensor 602 deviates from the standard environmental parameter range, this does not necessarily mean that the sensitivity and measurement accuracy of the first sensor 601 will necessarily be affected, nor does it necessarily mean that the credibility of the first oxygen concentration value is low. For safety considerations, at this time, it can be regarded that the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level, thereby improving the safety of personnel and equipment in the mine.

[0103] In the embodiments of this specification, by further observing whether there are safety risk events around the environmental parameter sensor, after evaluating the credibility of the risk event inferred from the first oxygen concentration value based on the environmental parameter value, a more detailed risk assessment can be further carried out. This further assessment can effectively reduce the possibility of missed reporting of risk events caused by the oxygen concentration value collected by the first sensor and improve the safety of personnel and equipment.

[0104] Based on the same idea, the embodiments of this specification also provide a device corresponding to the above method.

[0115] Optionally, the situation where the risk level corresponding to the first oxygen concentration value is less than the preset risk level may specifically include: If the oxygen concentration difference is greater than or equal to a third threshold, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0116] Optionally, the second sensor is located at the upwind position of the first sensor, and the first oxygen concentration value is greater than or equal to the second threshold.

[0117] Optionally, the first judgment unit may specifically include: A third judgment subunit, configured to judge whether the second oxygen concentration value is within the standard oxygen concentration range to obtain a fifth judgment result.

[0118] Optionally, the situation where the risk level corresponding to the first oxygen concentration value is less than the preset risk level may specifically include: If the fifth judgment result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it indicates that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0121] Optionally, the risk level corresponding to the first oxygen concentration value is less than the preset risk level, which may specifically include: If the sixth judgment result indicates that the second oxygen concentration value is within the standard oxygen concentration range, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0122] Optionally, the second sensor is located at the downwind position of the first sensor, and the first oxygen concentration value is greater than or equal to the second threshold.

[0123] Optionally, the first judgment unit may specifically include: A fifth judgment subunit, configured to judge whether the second oxygen concentration value is within the standard oxygen concentration range, and obtain a seventh judgment result.

[0124] A sixth judgment subunit, configured to, if the seventh judgment result indicates that the second oxygen concentration value is within the standard oxygen concentration range, judge whether the risk level corresponding to the first oxygen concentration value is greater than or equal to the preset risk level based on the oxygen concentration difference between the first oxygen concentration value and the second oxygen concentration value.

[0125] Optionally, the risk level corresponding to the first oxygen concentration value is less than the preset risk level, which may specifically include: If the oxygen concentration difference is greater than or equal to the fourth threshold, it means that the risk level corresponding to the first oxygen concentration value is less than the preset risk level.

[0129] Figure 7In the device, when the oxygen concentration value reported by the sensor for detecting the oxygen concentration in the mine exceeds the standard oxygen concentration range, if the risk level evaluated based on this oxygen concentration value is lower than the preset risk level, the alarm of the sensor this time can be determined as a false alarm. In this case, there is no need to trigger the first-level alarm information indicating that the workers need to evacuate the mine immediately, but only generate the second-level alarm information prompting that the mine environment needs to be further inspected. Through this hierarchical alarm mechanism, the number of emergency responses caused by false alarms of the sensor can be effectively reduced, thereby reducing the suspension of coal mining caused by false alarms, ensuring the continuity and safety of mine operations, and improving the coal mining efficiency.

[0130] Based on the same idea, the embodiments of this specification also provide the device corresponding to the above method.

[0132] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments. In particular, for Figure 8For the device shown, since it is basically similar to the method embodiment, the description is relatively simple. For related parts, please refer to the partial description of the method embodiment.

[0133] In the 1990s, it was quite obvious to distinguish whether an improvement in a technology was an improvement in hardware (e.g., improvement in circuit structures such as diodes, transistors, switches, etc.) or an improvement in software (improvement in method flows). However, with the development of technology, many improvements in method flows today can be regarded as direct improvements in hardware circuit structures. Almost all designers obtain the corresponding hardware circuit structures by programming the improved method flows into the hardware circuits. Therefore, it cannot be said that an improvement in a method flow cannot be implemented with a hardware entity module. For example, a programmable logic device (PLD) (such as a field programmable gate array (FPGA)) is such an integrated circuit whose logical function is determined by the user's programming of the device. The designer can program by himself / herself to "integrate" a digital system on a piece of PLD, without having to ask a chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, nowadays, instead of manually fabricating integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in program development and writing. The original code before compilation also has to be written in a specific programming language, which is called a hardware description language (HDL), and there is not only one kind of HDL, but many kinds, such as ABEL (Advanced Boolean Expression Language), AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc. The most commonly used ones currently are VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. Those skilled in the art should also be aware that as long as the method flow is slightly logically programmed with the above-mentioned several hardware description languages and programmed into the integrated circuit, it is easy to obtain the hardware circuit that implements the logical method flow.

[0134] The controller can be implemented in any suitable manner. For example, the controller can take the form of, for example, a microprocessor or a processor and a computer-readable medium storing computer-readable program code (such as software or firmware) executable by the (micro)processor, logic gates, switches, an application specific integrated circuit (ASIC), a programmable logic controller, and an embedded microcontroller. Examples of the controller include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. The memory controller can also be implemented as part of the control logic of the memory. Those skilled in the art also know that in addition to implementing the controller in the form of pure computer-readable program code, it is entirely possible to logically program the method steps to enable the controller to be implemented in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. to achieve the same functions. Therefore, such a controller can be considered a hardware component, and the devices included therein for implementing various functions can also be regarded as the structures within the hardware component. Or even, the devices for implementing various functions can be regarded as either software modules for implementing the method or structures within the hardware component.

[0135] The systems, devices, modules, or units illustrated in the above embodiments can be specifically implemented by computer chips or entities, or by products with certain functions. A typical implementation device is a computer. Specifically, the computer can be, for example, a personal computer, a laptop computer, a cellular phone, a camera phone, a smart phone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or any combination of these devices.
