[0036] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0037] As Figure 1 shown is a 5G-based underground mine personnel detection management system of the present application, comprising: a plurality of wearable detection devices and a ground management platform. The wearable detection devices are used for being worn by underground operation personnel to detect the body state of the operation personnel and the surrounding environment in real time.

[0038] In the embodiments of the present application, the ground management platform is connected with the plurality of wearable detection devices through a 5G network. The wearable detection devices perform data interaction with the ground management platform through the 5G network, which can ensure the stability of data transmission. The wearable detection devices send the detected data to the ground management platform and receive the control instructions sent by the ground management terminal.

[0039] In the embodiments of the present application, each wearable detection device specifically comprises a gas concentration sensor, a vital sign sensor, a data transceiver and a processor. The gas concentration sensor is used to detect the gas concentration around the worker. The vital sign sensor is used to detect the physical parameters of the worker. The data transceiver is used to transmit and receive data with the ground management platform. The processor is used to control the wearable detection device. Specifically, the processor executes instructions to control the gas concentration sensor and the vital sign sensor to detect data, and sends the detected data to the ground management platform through the data transceiver. At the same time, the processor can also make corresponding control according to the relevant information and control instructions sent by the ground management platform through the data transceiver.

[0040] It can be understood that the vital sign sensor can be used to detect the information of the heartbeat, body temperature, blood oxygen and heartbeat of the worker.

[0041] In the embodiments of the present application, several wearable detection devices are divided into corresponding device groups according to the work groups to which the workers wearing them belong. The ground management terminal generates a data uploading time planning table corresponding to each wearable detection device according to the number of devices of each device group and sends it to the corresponding wearable detection device. Several wearable detection devices perform data detection and uploading at corresponding time points according to the received data uploading time planning table in a cycle, so that the wearable detection devices in the same device group perform data detection and uploading in a certain order and time interval in turn.

[0042] It can be understood that the space under the mine is large, and the underground workers can be divided into different work groups according to different work areas. Therefore, corresponding to different work groups, the work personnel wearing wearable detection devices are divided into corresponding multiple device groups according to the work group to which the work personnel belongs. In this application, the ground management platform needs to judge the physical state of the underground work personnel and the environment under the ground according to the detection data of the wearable detection device. It can be understood that the wearable detection device is generally powered by a battery, and the workers in the same work group are in a relatively concentrated area. Therefore, in order to reduce the energy consumption of the wearable detection device and improve the use time, at one data upload time point, one device group is selected from each device group for data collection and upload work, and the detection data of one of the wearable detection devices in the device group is used to approximately judge the general situation of the area where the device group is located. Therefore, the ground management platform generates a data upload time planning table corresponding to each wearable detection device according to the number of devices in each device group and sends it to the corresponding wearable detection device. In this time planning table, the corresponding wearable detection device is set to perform data detection and upload work at what time point, and the wearable detection device only needs to work at the corresponding time point according to the setting in the time planning table, and at other times, the wearable detection device does not work, thereby reducing the energy consumption of the device. Preferably, during other time periods, the wearable detection device can actively enter a low-power state, and when data collection and upload are needed, it can be converted to a working state, thereby further improving the effect of reducing energy consumption. In this way, the wearable detection device is converted from the original data detection and upload operation at each data upload time point to one data detection and upload operation at multiple data upload time points.

[0043] In the embodiments of the present application, when the ground management platform receives data uploaded by the wearable detection device and the gas concentration in the data reaches the alarm range, the ground management platform sends first alarm information to the corresponding wearable detection device. When the ground management platform receives data uploaded by the wearable detection device and the body parameter in the data reaches the alarm range, the ground management platform sends second alarm information to the corresponding wearable detection device.

[0044] When the ground management platform receives data uploaded by the wearable detection device and the gas concentration in the data reaches the warning range, the ground management platform generates a unified planning table for the device group corresponding to the wearable detection device whose gas concentration reaches the warning range and sends it to each wearable detection device in the corresponding device group. The wearable detection devices in the device group simultaneously perform data detection and upload according to the received unified planning table at a certain time interval.

[0045] It can be understood that the alarm range is a more stringent index range than the early warning range. When the alarm range is reached, the ground management platform directly sends an alarm message. The early warning range is not as serious as the alarm range, and does not need to send an alarm message immediately. However, since the early warning range is relatively normal, there is a certain potential risk, so when the gas concentration reaches the early warning range, it indicates that there may be a certain safety hazard in the environment around the corresponding work group. Therefore, in order to eliminate safety hazards, when the gas concentration of a wearable detection device in a device group reaches the early warning range, the ground management platform will develop a unified planning table for this device group, and each wearable detection device in the device group will execute the same unified planning table, so that the data detection and uploading operation of each wearable detection device in the device group at each data uploading time point is converted from the original selection of one device in the device group for data detection and uploading.

[0046] As a more preferred embodiment, when the gas concentration in the data uploaded by the wearable detection devices in the same device group received by the ground management platform reaches the early warning range for a predetermined number of consecutive times, the ground management platform generates a unified planning table for the wearable detection devices in the device group and sends it to each wearable detection device in the corresponding device group. The wearable detection devices in the device group perform data detection and uploading at the same time according to the received unified planning table at a certain time interval.

[0047] Unlike the foregoing embodiments, in this embodiment, the ground management platform will only switch modes when the gas concentration in the data uploaded by the wearable detection devices in the same device group received reaches the early warning range for a predetermined number of consecutive times. Because there are many reasons for occasional reaching of the early warning range, and it cannot reflect the true level of gas in this area. Therefore, only when the gas concentration reported by multiple wearable detection devices in this device group reaches the early warning range continuously, will the mode be switched. In this way, the wearable detection device can be awakened for data collection as much as possible.

[0048] In the embodiments of the present application, when the number of gas concentrations in the data uploaded by the wearable detection devices in the device group executing the unified planning table reaching the early warning range is greater than the second preset number, the ground management platform sends first alarm information to each wearable detection device in the device group executing the unified planning table, and the second preset number is greater than the first preset number.

[0049] When the detection mode is switched, if the gas concentration detected by the plurality of wearable detection devices all reaches the pre-warning range, it indicates that there is a very big security risk in the area. At this time, without waiting for the gas concentration detected by the wearable detection device to reach the alarm range, the ground management platform directly sends the first alarm information to all wearable detection devices in the device group.

[0050] In the embodiments of the present application, when the gas concentration in the data uploaded by the wearable detection devices in the device group executing the unified planning table does not reach the pre-warning range for a certain number of times, the ground management platform sends the original data upload time planning table to each wearable detection device in the device group executing the unified planning table.

[0051] After mode conversion, if the gas concentration detected by any wearable detection device in the device group does not reach the pre-warning range for a certain period of time, the detection mode is switched to the original sequential detection mode.

[0052] In the embodiments of the present application, the 5G-based mine personnel detection management system further comprises: a plurality of drilling machines.

[0053] The plurality of drilling machines are operated by workers, and the drilling machines can be wirelessly connected with the wearable detection devices. The wearable detection device receiving the first alarm information sends a lock machine instruction to the corresponding drilling machine, and the drilling machine receiving the lock machine instruction is automatically locked.

[0054] It can be understood that when the gas concentration is high, using a drilling machine for operation has a big fire hazard. Therefore, after the wearable detection device receives the first alarm information, the drilling machine operated by the worker is directly locked by the wearable detection device through wireless data interaction, immediately stopping the current risky operation or preventing misoperation.

[0055] In the embodiments of the present application, the wearable detection device further comprises: a correction module.

[0056] The correction module is used to correct the gas concentration information detected by the gas concentration sensor. The correction module records the initial concentration information of the gas concentration sensor in a normal environment, and corrects the real-time detected gas concentration information through the initial concentration information when the gas concentration sensor is working normally.

[0057] It can be understood that the gas concentration sensor may be aged after a period of use. The detected gas concentration information of the aged gas concentration sensor is not accurate enough, and there will be degrees even in a normal environment with 0 gas content. Therefore, in order to reduce the problem of inaccurate detection data of the gas concentration sensor caused by aging, in the present application, the detection data of the aged gas concentration sensor is corrected in real time by the correction module. Specifically, before use, a simulated detection is performed outside the well, at which time the correction module records the initial concentration information of the gas concentration sensor in a normal environment. When actual detection is performed during downhole operation, the correction module corrects the real-time detected gas concentration information by the initial concentration information. In the present application, the corrected gas concentration is obtained by subtracting the initial concentration information from the real-time detected gas concentration information.

[0058] In the embodiments of the present application, the ground management platform comprises a personnel information registration module, a personnel dispatching module and a detection equipment binding module.

[0059] The personnel information registration module is configured to register the identity information of the operation personnel. The personnel dispatching module is configured to group the operation personnel according to needs. The detection equipment binding module is configured to bind the wearable detection equipment to the corresponding operation personnel.

[0060] In the embodiments of the present application, when receiving the second alarm information, the operation personnel need to judge their own physical condition according to the alarm information. When the operation personnel think that the operation needs to be suspended, they can send a suspension information to the ground management platform through the wearable detection equipment. When receiving the suspension information, the ground management platform adds new operation personnel to the corresponding work team through the personnel dispatching module, and binds new wearable detection equipment to the new operation personnel through the detection equipment binding module.

[0061] The basic principles, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the above embodiments do not limit the present application in any form, and any technical solution obtained by equivalent replacement or equivalent transformation falls within the protection scope of the present application.
