Unless the context clearly indicates otherwise, the definition of a term is consistent throughout the specification.

[0022] like Figure 1 As shown, an embodiment of the present invention provides a mine personnel positioning method based on wireless communication, comprising: Step S102: obtaining device information and environmental information uploaded by the mining personnel's device, wherein the device information includes attribute information and positioning information.

[0023] Specifically, the system captures real-time device information uploaded by communication-related devices carried by miners during their tasks, as well as environmental information within the mine. Miners' devices can obtain current device attributes, including the device's unique identifier (device ID, personnel ID, etc.), hardware information (communication protocol version, calibration parameters, etc.), data content (device battery voltage, signal strength, signal-to-noise ratio), user-associated information (user's heart rate and other physical conditions), and positioning information, including the device's current three-dimensional coordinates, motion status, and trajectory. Furthermore, the system can monitor environmental risks within the mine. Environmental risk data collection includes real-time ambient gas data (including concentrations of key gases within the mine: methane, carbon monoxide, and oxygen), physical environmental data (including temperature, humidity, and air pressure), and geological parameters monitored by miners in real time, such as soil survey data. Collecting this data provides high-precision input for subsequent equipment fault diagnosis and environmental risk analysis.

[0024] Step S104: determine whether the device has a failure risk based on the device information and environmental information. If the device has a failure risk, detect in real time whether the positioning information is abnormal.

[0025] Specifically, a comprehensive assessment of equipment and environmental information is conducted to determine whether a device is at risk of failure. Failure risk refers to the possibility of equipment failure, encompassing not only actual equipment failure but also significant data errors and a threshold for the likelihood of a failure. This assessment can be made from several perspectives, including: assessing the health of the device itself. This involves predicting the probability of failure in the current mining environment based on device attributes such as battery voltage, operating temperature, and communication signal strength. When these attributes reach the failure threshold, a failure risk is identified. This is then coupled with environmental information to determine whether a device is at risk of failure by measuring fluctuations in device readings under the current environment. For example, when the mine temperature exceeds 40°C, this is done to determine whether the device is at risk of failure. Furthermore, fault assessment using positioning data, such as trajectory changes, can be used to determine whether a failure risk exists based on speed limits and spatial constraints.

[0026] Furthermore, the above data can be used to determine whether the equipment is at risk of failure. If a failure risk exists, indicating a potential equipment problem, positioning information must be constantly monitored to determine if there are any anomalies to ensure the safety of mine workers. Positioning information anomaly detection includes verifying uncontrolled constraints, such as speed limits for mine workers (detecting whether walking speeds exceed the limit), spatial constraints (using the mine GIS map to determine whether the positioning point deviates from the tunnel buffer zone (±5 meters)), and monitoring for signal loss, such as UWB positioning signal loss or Bluetooth beacon matching failure.

[0027] Step S106: When the positioning information is abnormal, obtain devices from the same batch and detect the source of the abnormality in combination with the device information of the devices from the same batch.

[0028] Specifically, when an anomaly in positioning information is detected, the device information of the same batch of equipment is obtained. The same batch of equipment refers to equipment of the same model and deployed in the same area. For example, the equipment ID batch code can be used to quickly screen the equipment carried by other staff members in the same batch. It can also be the same batch of equipment information in different base stations within the mine. The same batch of equipment information also includes attribute data (voltage, temperature), positioning data (coordinates, signal strength), and environmental information. Combined with the equipment information of the same batch of equipment, it is detected whether the source of the anomaly is the equipment source or the environmental source.

[0029] Furthermore, device-source anomaly determination identifies positioning anomalies caused by device failures. Environmental-source determination identifies positioning failures caused by sudden changes in the mine environment (such as landslides and gas outbursts). The specific determination process involves combining statistical analysis of group device information with the assumption that a device failure risk has been identified in the previous step to accurately determine the anomaly source.

[0030] Among them, the abnormal situation of positioning information can be, for example, a sudden drop in the battery voltage of the device itself, an abnormal increase in temperature, a continuous deterioration of the communication signal quality, and a discrete positioning point and abnormal trajectory of a single device. Then the above abnormalities are compared with the information of other devices in the same batch of devices, and a judgment is made based on the comparison results. For example, if the abnormality rate of devices in the same batch is less than the preset ratio, such as less than 10%, it tends to be a device source failure. If the abnormality rate is >10%, further analysis of environmental factors is required. Furthermore, when it tends to be a device source failure, all uploaded data from the device source is threshold-compared. When the threshold comparison result is a data abnormality, it is determined to be a device source failure. When it tends to be an environmental failure, all environmental parameters are coupled and analyzed, and the possibility of environmental accidents is judged by a spatial clustering algorithm. When the possibility is greater than the preset possibility, it is determined to be an environmental source failure.

[0031] Step S108: When the abnormality originates from a device, a backup device recovery plan is pushed to devices in the same batch.

[0032] Specifically, when the source of the abnormality is the device source, the device positioning function should be quickly restored. If it cannot be responded in time, the relevant personnel should be reminded to stop working in the mine. Among them, the specific plan is to determine different backup equipment recovery plans according to the abnormality type of the device source. For example, when the main positioning plan, such as UWB positioning, is abnormal, it switches to the Bluetooth beacon, that is, through the built-in Bluetooth module of the device and the pre-installed tunnel Bluetooth beacon map, Bluetooth scanning is performed to match the nearest beacon for positioning. It is also possible to repair the device by pushing firmware patches, such as repairing the signal verification algorithm. The backup equipment recovery plan will be pushed to the same batch of equipment, and the same batch of equipment will be used as relay nodes. When the data transmission capacity of the device is also abnormal, the same batch of equipment can implement the equipment recovery plan nearby.

[0033] Step S110 : When the abnormality source is an environmental source, a warning level and a target area are determined based on the device information and the environmental information, and a corresponding rescue plan is selected based on the warning level and the target area.

[0034] Specifically, when the source of the anomaly is environmental, it means that environmental factors have caused the anomaly of personnel and equipment, and personnel may be at risk of safety. In this case, precise rescue needs to be initiated based on the warning level and the location of the failure point. The last valid location is determined based on the last information before the failure, that is, the failure point is located. Then, combined with the mine GIS map, environmental information, and task information, the target area where personnel may be located is analyzed, and then the warning level is determined based on the situation in the specific area. Among them, the determination of the warning level is seen by obtaining the key parameters in the equipment information and environmental information, establishing a key parameter coupling model and assigning parameter weights, and calculating the comprehensive risk value. Among them, the key parameters include equipment status, positioning, anomaly marks (such as the number of communication interruptions), gas concentration, geological vibration intensity, roof pressure, air pressure, etc., coupling multiple parameters, and then matching the historical database. The comprehensive risk value under the corresponding key parameters is detected by the neural network model algorithm, and the warning level is determined by the comprehensive risk value.

[0035] Furthermore, a Level 1 alert indicates a critical situation in a specific area. For example, if the oxygen concentration in the area is decreasing at a rate exceeding 0.5% / minute and ventilation is very poor, a mine-wide alert can be issued, notifying the entire mine to evacuate. Rescue robots or drones can be deployed with oxygen cylinders to the point of failure, and a rescue team can be dispatched. For example, if the methane concentration in the mine is around 2.5%, a Level 2 alert can be issued. Under this alert, personnel are notified to evacuate the area and a temporary ventilation corridor can be established. For example, if the environmental data in the area is relatively normal, but the mine GIS map indicates data anomaly risks or a history of accidents in the corresponding area, a Level 3 alert can be issued, conducting a single-point investigation of the anomaly and guiding personnel to a safe area. This provides more accurate warnings to mine personnel, enabling a rapid response while reducing the risk of misjudgments and secondary accidents.

[0036] The embodiment of the present invention provides a method for positioning mine personnel based on wireless communication, which obtains device information and environmental information uploaded by the mine personnel's equipment, wherein the device information includes attribute information and positioning information; determines whether the equipment has a failure risk based on the device information and environmental information; when the equipment has a failure risk, detects in real time whether the positioning information is abnormal; when the positioning information is abnormal, obtains equipment from the same batch, and detects the source of the abnormality in combination with the device information of the same batch of equipment; when the abnormality source is the equipment source, pushes the backup equipment recovery plan to the equipment from the same batch; when the abnormality source is the environmental source, determines the warning level and target area based on the device information and environmental information, and selects the corresponding rescue plan based on the warning level and target area. In this way, the abnormality of the mine personnel's positioning information can be detected in a timely manner, and when the positioning information is abnormal, the cause of the abnormality can be accurately determined, and the corresponding treatment plan can be selected according to the cause of the abnormality, thereby improving the safety factor of the mine personnel.
