Taking a server to execute the method as an example, the mine geotechnical engineering emergency linkage monitoring method based on accurate positioning in the embodiment of the disclosure is described below, and referring to fig. 2, the mine geotechnical engineering emergency linkage monitoring method based on accurate positioning in the embodiment of the disclosure may include the following steps:

Next, step S201 to step S204 will be described in detail.

In step S201, underground mine environment monitoring data and environment reference data are acquired.

In an example embodiment of the present disclosure, the underground mine environment monitoring data refers to various types of data collected in the underground mine environment by a series of sensors and devices. The underground mine environment monitoring data is past first environment monitoring data and second environment monitoring data, the first environment monitoring data is monitoring data which directly influences the underground environment dangerous degree, for example, the first environment monitoring data can comprise at least one of gas monitoring data, carbon monoxide monitoring data and wind speed monitoring data, the second environment monitoring data is monitoring data which can influence the accuracy of the measured value of the first environment monitoring data, for example, the second environment monitoring data can comprise at least one of temperature monitoring data, humidity monitoring data and air pressure monitoring data.

Specifically, the working principle of the gas sensor is that the gas and a semiconductor material element in the sensor undergo oxidation-reduction reaction, so that the resistance value of the element is changed, the gas concentration can be determined by measuring the change of the resistance value, and the temperature can influence the measurement of the gas monitoring data by the gas sensor because the temperature can influence the change of the refractive index caused by the density of the gas. The working principle of the carbon monoxide sensor is that when carbon monoxide reacts with oxygen at high temperature, current output is generated, so that the concentration of carbon monoxide can be monitored by detecting the output of the current, and the humidity can influence the adsorption and desorption processes of gas on the surface of the sensor, so that the humidity monitoring data can influence the measurement of the carbon monoxide monitoring data by the carbon monoxide sensor. The working principle of the wind speed sensor is based on the relation between the air flow rate and the pressure difference, the sensing part of the wind speed sensor consists of three or four conical or hemispherical empty cups, the whole transverse arm support is fixed on a vertical rotating shaft, when wind blows through the empty cups, the cups can generate rotating motion, so that the pointer is driven to point to corresponding wind speed scales, as the gas density changes along with the change of the air pressure, the air density is small, the monitoring wind speed value is larger in a low-pressure environment, and the air density is large, the monitoring wind speed value is smaller in a high-pressure environment, so that the air pressure monitoring data can influence the measurement of the wind speed monitoring data.

The environmental reference data refers to a series of standardized data that are referenced when operating on underground mine environmental monitoring data. In an example embodiment of the present disclosure, the environmental reference data includes environmental reference monitoring data, sensor reference compensation data, and sensor limit reference data. The environmental reference monitoring data refers to environmental data required by the sensor in a normal working state, the sensor reference compensation data refers to a difference value between the environmental data in which the sensor is in an actual working state and the environmental data required in the normal working state, the sensor limit reference data refers to a maximum value or a minimum value of working environmental data set by a pointer for a specific type of sensor equipment, and when the environmental data in which the sensor is located exceeds or falls below the set values, the sensor may not work normally or even be damaged.

The underground mine environment monitoring data may be obtained in real time, or may be buffered in a short time and then batch-transmitted to the server according to a predetermined time, for example, the collected data may be temporarily stored in a local device, and then the buffered data may be batch-uploaded to the server through a network connection within a predetermined time, and the time may be set to be 1 minute, 10 minutes, half hour, etc., which is not particularly limited in this example embodiment.

In step S202, monitoring data conversion values and anomaly ratios are determined based on the underground mine environment monitoring data and environment reference data.

In an example embodiment of the present disclosure, the monitoring data conversion value refers to a true value of environmental monitoring data obtained by adjusting or correcting the data monitored by the sensor. The adjustment or modification may include some form of mathematical transformation of the data, such as logarithmic transformation, square root transformation, etc., or may include calibrating or calibrating the data to eliminate systematic errors of the sensor itself, or may include adjusting the data according to the relationship between the influencing factors and the errors, which is not particularly limited in this example embodiment. For example, if the sensor is subject to interference in a high humidity environment to produce a large reading, and is relatively stable in a low humidity environment, then some adjustments or corrections may be made to the data in the high humidity environment to make it more realistic.

The abnormal ratio is the ratio of the value acquired by each sensor to the limit value of the sensor, is used for measuring whether the environment under the mine is abnormal, and the partial abnormal ratio is the ratio of underground mine environment monitoring data which can influence certain sensor monitoring data to corresponding sensor limit reference data. If the partial abnormal ratio is larger than 1, the underground mine environment monitoring data monitored by the sensor exceeds the normal range, and potential safety hazards exist, otherwise, if the partial abnormal ratio is smaller than 1, the value of the underground mine environment monitoring data is within the normal acceptable range. The abnormal ratio can comprehensively reflect the safety condition of the whole mine environment, and if the abnormal ratio exceeds a certain safety threshold, condition early warning and safety inspection are needed immediately.

In step S203, determining an underground mine environment state according to the abnormal ratio, if it is determined that the underground mine environment state is a dangerous state, determining an underground environment early warning type and an underground environment early warning level based on the monitored data conversion value and the abnormal ratio, and matching an emergency rescue treatment measure through the underground environment early warning type and the underground environment early warning level.

In an example embodiment of the present disclosure, the downhole environment early warning type is a type for displaying possible accident risks under the mine, for example, the downhole environment early warning type may be an explosive environment early warning type caused by too high gas concentration, a toxic environment early warning type caused by too high carbon monoxide concentration, or a high pressure environment early warning type caused by too low wind speed value, which is, of course, only illustrative, and specifically may be set in a customized manner according to practical situations, and the present example embodiment is not limited in this way.

The underground environment early warning level refers to a parameter for measuring a risk level corresponding to a current underground environment early warning type, for example, the underground environment early warning type can be an explosive environment early warning type, and correspondingly, the underground environment early warning level can be divided into a primary explosive environment early warning, a secondary explosive environment early warning, a tertiary explosive environment early warning and a quaternary explosive environment early warning, and the smaller the number is, the higher the risk level is indicated. Of course, the downhole environment early warning level is only schematically illustrated, and specifically, the downhole environment early warning level can be set in a self-defined manner according to practical situations, and the embodiment of the present invention is not limited in particular.

The emergency rescue treatment measures refer to corresponding treatment measure contents which are proposed for different early warning types and early warning levels and are proposed in the emergency rescue treatment plan file after examination and approval.

The underground mine environment state can be determined according to the abnormal ratio, if the underground mine environment state is determined to be a dangerous state, the underground environment early warning type and the underground environment early warning level can be determined based on the monitoring data conversion value and the abnormal ratio, and the emergency rescue treatment measures are matched through the underground environment early warning type and the underground environment early warning level.

In step S204, an associated emergency linkage terminal is started according to the emergency rescue handling measure, so as to implement emergency linkage rescue through the started emergency linkage terminal.

In an example embodiment of the present disclosure, the emergency linkage terminal refers to a setting for implementing emergency linkage rescue, for example, the emergency linkage terminal may be an audible and visual alarm terminal for notifying personnel of a related emergency rescue organization, a real-time monitoring terminal for feeding back emergency rescue data, or an accurate positioning terminal for positioning each temporary emergency rescue object under a mine, or an environment control terminal for adjusting an environment under the mine to implement emergency rescue, and of course, the emergency linkage terminal may also be two or more of the above devices, which is not particularly limited in this example embodiment.

For example, the emergency rescue treatment measures can be notifying the related emergency rescue staff to perform emergency rescue actions, then displaying emergency early warning data to the related monitoring staff, and performing technical support and data recording by the related professionals; meanwhile, nearby rescue resources are scheduled to realize temporary emergency rescue, and pollution isolation and environmental protection are carried out on underground environment. Correspondingly, the associated audible and visual alarm terminal can be started according to the early warning notification measures in the emergency rescue treatment measures, so that the audible and visual alarm terminal can remind personnel of an emergency rescue working mechanism to carry out emergency rescue actions; the related real-time monitoring terminal can be started according to the data feedback measures in the emergency rescue treatment measures, so that the real-time monitoring terminal can display the monitoring data conversion value, the abnormal ratio, the underground environment early warning type, the underground environment early warning level, the response state of each emergency rescue worker and other data such as an underground environment real-time image and the like; the associated accurate positioning terminal can be started according to nearby rescue resource mobilization measures in emergency rescue treatment measures, so that nearby rescue objects near the underground environment early-warning position can be notified through the accurate positioning terminal to perform emergency rescue actions; the associated environment control terminal can be started according to the environmental emergency rescue equipment scheduling measures in the emergency rescue treatment measures, so that the underground environment early-warning position can be isolated from pollution and protected from environment through the environment control terminal.

The real measured value of the sensor is obtained by determining the monitoring data conversion value, so that the underground environment danger level is determined by combining the abnormal ratio, the accuracy and the precision of the data processing process are improved, and the effectiveness of the selected emergency linkage measures is ensured; the sensor interfaces of multiple types are configured in the same collector at the same time, and the acquired sensor signals of multiple types are normalized, so that the problem of data distortion or misalignment of a data acquisition link is avoided, and the accuracy of a data acquisition process is improved; the emergency rescue scheme can be automatically generated according to the early warning type and the early warning level, and related emergency rescue resources are called to realize emergency linkage rescue, so that the response speed of the emergency linkage rescue is improved, and the emergency linkage rescue efficiency is improved.

The technical solutions involved in step S201 to step S204 are explained in detail below.

In an exemplary embodiment of the present disclosure, the following steps may be implemented:

the monitoring data conversion value may be determined based on the first environmental monitoring data, the second environmental monitoring data, the environmental reference data, and the sensor reference compensation data, and the anomaly ratio may be determined based on the second environmental monitoring data and the sensor limit reference data.

The difference value between the second environmental monitoring data and the environmental reference data can be calculated, and then the sensor compensation data is combined to calculate the error value of the first environmental monitoring data caused by the abnormality of the second environmental monitoring data, so that the monitoring data conversion value can be calculated according to the first environmental monitoring data and the error value, that is, the real numerical value corresponding to the first environmental monitoring data, a large amount of the first environmental monitoring data, the second environmental monitoring data, the environmental reference data and the sensor reference compensation data can be collected as training samples, a far linear regression model or a neural network model is trained, and the monitoring data conversion value is determined by inputting the data into the model.

By correcting the first environment monitoring data, the monitoring data conversion value capable of reflecting the underground real environment is obtained, workers can be helped to better understand and analyze the environment monitoring data, the accuracy of the environment monitoring data is improved, meanwhile, the first environment monitoring data is self-calibrated, manual intervention can be reduced, and the working efficiency of the system is improved.

In an exemplary embodiment of the present disclosure, the monitoring data conversion value includes a gas conversion value, a carbon monoxide conversion value, and a wind speed conversion value, the environmental reference data includes a temperature reference data, a humidity reference data, and a barometric pressure reference data, the sensor reference compensation data includes a gas sensor reference compensation data, and the carbon monoxide sensor reference compensation data and the wind speed sensor reference compensation data, while determining the monitoring data conversion value based on the first environmental monitoring data, the second environmental monitoring data, the environmental reference data, and the sensor reference compensation data may be implemented.

Specifically, the gas conversion value may be determined by the following formula (1):

the method comprises the steps of carrying out a first treatment on the surface of the Formula (1)

Wherein,indicating the gas conversion value, +.>Indicating gas monitoring data,/-, and>representing the temperature-monitoring data of the temperature,representing temperature reference data, ">And representing the reference compensation data of the gas sensor corresponding to each degree of temperature difference.

The carbon monoxide conversion value can be determined by the following formula (2):

the method comprises the steps of carrying out a first treatment on the surface of the Formula (2)

Wherein,representing carbon monoxide conversion value, ">Representing carbon monoxide monitoring data,/-, and>representing humidity monitoring data, ">Indicating humidity reference data, ">Representing carbon monoxide sensor reference compensation data corresponding to each percentage humidity difference.

The wind speed conversion value may be determined by the following formula (3):

the method comprises the steps of carrying out a first treatment on the surface of the Formula (3)

Wherein,representing wind speed transition value,/-, and>representing wind speed monitoring data,/-, and>indicating barometric pressure monitoring data,/-, and>representing barometric pressure reference data, +.>And representing the reference compensation data of the wind speed sensor corresponding to the air pressure difference per pascal.

By monitoring and self-correcting the underground gas concentration, the carbon monoxide concentration and the wind speed, the situation that personnel are poisoned and choked to die due to the too high carbon monoxide concentration and underground gas explosion is caused by the too high gas concentration or the too high wind speed can be avoided, the working safety of underground workers is improved, meanwhile, the self-corrected data have higher credibility and accuracy than the original monitoring data, and the guarantee is provided for the accuracy of the subsequent underground safety state judgment.

In an exemplary embodiment of the present disclosure, the sensor limit reference data includes temperature sensor limit reference data, humidity sensor limit reference data, and air pressure sensor limit reference data, while determining the anomaly ratio based on the second environmental monitoring data and the sensor limit reference data may be implemented.

The anomaly ratio can be determined by the following equation (4):

the method comprises the steps of carrying out a first treatment on the surface of the Formula (4)

Wherein,representing abnormal ratio->Representing temperature monitoring data, < >>Representing humidity monitoring data, ">Indicating barometric pressure monitoring data,/-, and>reference data representing temperature sensor limits, +.>Representing humidity sensor limit reference data,representing barometric sensor limit reference data.

Compared with a single evaluation index, the deviation degree of the second environment monitoring data is comprehensively evaluated, the underground safety condition can be more accurately and comprehensively reflected, the accuracy and sensitivity of underground safety monitoring are improved, the safety of underground operation is enhanced, meanwhile, the data of each sensor is converted into an abnormal ratio, the data processing flow is simplified, and the information processing efficiency is improved.

In an exemplary embodiment of the present disclosure, determining an environmental state of an underground mine according to an anomaly ratio may be achieved by:

The preset abnormal ratio threshold value can be obtained, if the abnormal ratio is determined to be greater than or equal to the abnormal ratio threshold value, the state of the underground mine environment is determined to be a dangerous state, and if the abnormal ratio is determined to be less than the abnormal ratio threshold value, the state of the underground mine environment is determined to be a safe state.

The abnormal ratio threshold is a parameter for measuring the dangerous state of the downhole environment, for example, the abnormal ratio threshold is 300% or 200%, and specifically may be set in a self-defined manner according to the actual use condition, which is not particularly limited in this exemplary embodiment.

Optionally, a dangerous extremum can be set for each of the gas monitoring data, the carbon monoxide monitoring data, the wind speed monitoring data, the temperature monitoring data, the humidity monitoring data and the air pressure monitoring data according to the underground actual conditions, and the underground environment dangerous level is directly determined to be the highest dangerous level as long as a certain monitoring data or a conversion value thereof is greater than or equal to the corresponding dangerous extremum without calculating the underground dangerous coefficient at the moment.

In an exemplary embodiment of the present disclosure, referring to FIG. 3, determining a downhole environmental risk level based on monitoring data conversion values and anomaly ratios may be accomplished by:

In step S301, preset risk level weight data is acquired;

in step S302, a risk coefficient is determined based on the risk level weight data, the monitored data conversion value, and the anomaly ratio value;

in step S303, a downhole environmental risk level is determined based on the risk coefficient.

The risk level weight data refers to weight distribution data of the influence of the monitored data conversion value and the abnormal ratio on the risk level. In the embodiment of the disclosure, the risk level weight data includes conversion value weight data and abnormal ratio weight data. For example, the conversion value weight data may be set to 0.4, the corresponding abnormal ratio weight data may be set to 0.6, or the conversion value weight data may be set to 0.5, the corresponding abnormal ratio weight data may be set to 0.8, etc., specifically, the conversion value weight data may be further divided into gas weight data, carbon monoxide weight data and wind speed weight data, which may reflect the importance of the two and may adjust the contribution of each input value to the output result, which is not particularly limited in this exemplary embodiment.

Alternatively, the risk level weight data may be obtained from a database, or may be obtained from a specific configuration file, or may be obtained from a memory buffer, where the manner of obtaining the risk level weight data is not particularly limited in this example embodiment.

The risk factor can be determined by the following equation (5):

the method comprises the steps of carrying out a first treatment on the surface of the Formula (5)

Wherein,representing risk factors->Representing gas weight data, +.>Representing carbon monoxide weight data,/->Representing wind speed weight data,/->Indicating the gas conversion value, +.>Representing wind speed transition value,/-, and>representing carbon monoxide conversion value, ">Weight data representing abnormal ratio ++>Representing the anomaly ratio.

The underground environmental risk level refers to a risk level classified and evaluated according to various environmental risk factors inside the mine, and these risks may include gas explosion or oxygen deficiency of underground personnel due to abnormality of temperature, humidity and wind speed, etc. In the example embodiments of the present disclosure, the downhole environmental risk level may be classified into low risk, medium risk, high risk, and extremely high risk, and may be classified into primary risk, secondary risk, and tertiary risk, etc., which the example embodiments are not particularly limited to.

The environmental risk level can be divided according to the value of the abnormal ratio, the value of the abnormal ratio is divided into different environmental risk levels in different intervals, the monitoring data conversion value and the underground environmental risk level can be comprehensively evaluated, if corresponding weight data are set, the monitoring data conversion value and the underground environmental risk level are multiplied by the corresponding weight data respectively and then summed, and finally a specific environmental risk level is determined according to the operation result, and when a certain monitoring data conversion value seriously exceeds the standard, the monitoring data conversion value can be directly divided into the highest risk level, so that early warning can be carried out in the shortest time, and the embodiment of the invention does not limit the method in particular.

After the preset dangerous grade weight data are obtained, the dangerous coefficient is determined by comprehensively considering the dangerous grade weight data, the monitoring data conversion value and the abnormal ratio, the danger of the underground environment can be estimated more accurately and more in real time, and the safety of staff is further improved.

In an exemplary embodiment of the present disclosure, the matching of emergency rescue treatment measures by the downhole environment pre-warning type and the downhole environment pre-warning level may be achieved by:

the method comprises the steps that a pre-constructed emergency rescue database can be obtained, then first early warning treatment measures can be matched from the emergency rescue database according to first early warning keywords corresponding to the underground environment early warning types, and second early warning treatment measures can be matched from the emergency rescue database according to second early warning keywords corresponding to the underground environment early warning levels; and finally, carrying out data fusion on the first early warning treatment measure and the second early warning treatment measure to obtain the emergency rescue treatment measure corresponding to the underground environment early warning type and the underground environment early warning level.

The emergency rescue database is a preset database for storing information related to emergency rescue measures, and can be used for extracting keywords corresponding to all the early warning treatment measures in the approved emergency rescue treatment plan file, and forming a database formed by early warning measure keyword groups according to the keywords, wherein different early warning measure keyword groups correspond to different early warning treatment measures in the emergency rescue treatment plan file.

The first pre-warning keywords refer to keywords corresponding to the pre-warning type of the downhole environment, for example, taking the pre-warning type of the downhole environment as the pre-warning type of the downhole gas and coal dust explosion as an example, the first pre-warning keywords may be "gas", "coal dust", "explosion", etc., which is not particularly limited in this example embodiment.

The first early warning treatment measure refers to early warning treatment measures related to the underground environment early warning type in the emergency rescue treatment plan file, for example, the underground environment early warning type can be an underground gas and coal dust explosion early warning type, and the first early warning treatment measure can be "try to send an alarm notice to personnel possibly affected by the underground gas and coal dust explosion catastrophe; if there is a plenum at the disaster avoidance site, the valve should be opened to provide oxygen ", which is, of course, only schematically illustrated herein, and the present exemplary embodiment is not limited thereto.
