Fig. 1 is a schematic flow chart of a mine staff monitoring method in an embodiment of the present application, where an execution main body of the method may be a server, and the server may be a ground workstation used by ground staff to monitor a mine. As shown in fig. 1, the mine personnel monitoring method may include the steps of:
and S101, acquiring an original address information set in a mine area to be operated.
In this embodiment, since the ground worker cannot know the underground situation of the mine worker in real time through the server, the worker cannot be quickly and effectively organized to evacuate to the ground when a danger occurs. Therefore, before the mine worker enters the mine area to be operated, the original address information set of the mine area is obtained, namely the address information of each mine lamp in the mine area, the address information of a mobile terminal carried by the mine worker and the address information of a gas detection module used for detecting toxic gas in a preset target area where the mine lamp is located are collected, so that the working state of the mine worker in the mine is monitored conveniently.
Optionally, as shown in fig. 2, fig. 2 is a first structural schematic diagram of a mine gas monitoring system, and if the gas detection module 10 in the current mine is not mounted on a mine lamp but is independently installed in the mine, the address information of the mine lamp and the address information of the gas detection module 10 need to be written in the original address information respectively; the gas detection module 10 may be mounted on a mine lamp integrated in the target area, the mine lamp is a mine lamp for illumination in a mine, the gas detection module 10 is mounted on each mine lamp in the mine, and each basic module in the mine lamp is used to provide support for the gas detection module 10, so as to achieve more effective utilization of the mine lamp, for example, a power module arranged in the mine lamp can supply power to the gas detection module 10. If the gas detection module 10 in the current mine is mounted on the mine lamp, the address information of the mine lamp and the address information of the gas detection module 10 can be regarded as one, and the address information of the mine lamp and the address information of the gas detection module 10 can be regarded as the address information of the mine lamp and the address information of the mine lamp.
Alternatively, the mobile terminal 60 may be a head lamp carried by a mine worker. Because the existing working head lamp can be equipped with wireless connection communication functions, such as bluetooth and ZigBee, the mobile terminal 60 generally adopts the head lamp worn by mine workers, and after the mine lamp in the mine area is also matched with the communication module 50, each mobile terminal 60 is equivalent to one mine worker.
Alternatively, the in-well distribution information of all currently existing mines may be entered in the server 40 in advance, and the in-well distribution information includes detailed information including address information of each mine lamp in the mine, detailed information including address information of each gas detection module 10, detailed information including address information of other working modules in the mine, and the like. Therefore, before the operation is carried out on a certain mine, only the address information of the mobile terminal 60 entering the mine needs to be input, and other required detailed information can be directly obtained from the corresponding database of the server 40, so that the operation of a user is facilitated.
It can be understood that, because one operation task and simultaneous work development may include at least two mines and a plurality of different spaces such as an underground chamber which needs to be opened in the current operation task, the mine operation personnel to be operated need to be distributed to determine the original address information sets in the mine areas of the mines to be operated. The chambers are generally used for resting and storing equipment and the like for operating personnel, so that no mine operating personnel exist in the currently opened chambers when a task is started.
As a specific example, but not by way of limitation, the current job task needs to be performed simultaneously by using mines 1 to 5, so that 5 batches of mine workers need to enter the 5 mines to perform job at the same time, and the original address information sets of the 5 mines can be obtained before the job, which are:
a set of original address information 1 about the mine 1, a mine lamp (a1, a2.. An); a mobile terminal (a1, a2.. an);
original address information set 2 about mine 2, miner's lamp (B1, B2.. Bn); a mobile terminal (b1, b2... bn);
a set of original address information 3 about mine 3, miner's lamp (C1, C2... Cn); a mobile terminal (c1, c2... cn);
a set of original address information 4 about mine 4, miner's lamp (D1, D2... Dn); a mobile terminal (d1, d2.. dn);
a set of original address information 5 about the mine 5, mine lights (E1, E2.. En); a mobile terminal (e1, e2... en);
a set of original address information 6 about the chamber, miner's lamps (F1, F2... Fn);
under normal conditions, each mine operator entering the mine 1 needs to carry a respective mobile terminal 60, namely the mobile terminal a1 to the mobile terminal an in the original address information set 1, and the mobile terminals a1 to an are connected with the mine lamp in the mine 1 through the communication module 50. Because the communication module 50 is in wireless communication connection in the connection between the mobile terminal 60 and the miner's lamp, and the wireless communication connection is required to be close in distance, the connection effect is good only in a certain range, the server 40 can obtain the miner's lamp address information and the connection information of the wireless connection through the mobile terminal 60 to determine whether the mobile terminal 60 is still in the original address information set 1. For the connection between the miner's lamp and the mobile terminal 60, the communication module 50 may adopt a ZigBee communication unit or a bluetooth communication unit, etc. disposed therein; the respective address information corresponding to the miner's lamp and the mobile terminal 60 in the entire original address information set, for example, a subset of the entire original address information set, i.e., a1 through An and a1 through An in the original address information set 1, respectively represent specific physical addresses of the corresponding devices, for example, MAC addresses.
As shown in fig. 3, fig. 3 is a schematic structural diagram of the mine personnel monitoring system, each mobile terminal 60 is provided with a unique MAC address, and after the mobile terminal is connected to the mine lamp, the server 40 can read the address of the mobile terminal 60 through the mine lamp 110 and can read which mine lamp the mobile terminal 60 is respectively connected to. Specifically, the process further includes the DMX controller 100, which is mainly used to assign address information to the miner's lamp and is connected to the server 40, so as to send the detailed information of the current connection status detected by the miner's lamp, the various miner's lamp information of the miner's lamp, such as the address of the miner's lamp, the methane gas information detected by the lamp, and the operator information in the current target area to the server 40. Since the addresses of the mine lamps and the numbers of the mine wells in which the mine lamps are located are stored in the server 40 in advance, the mine well in which each mobile terminal 60 is currently located can be judged according to the mine lamp connected to each mobile terminal 60, that is, the mine well in which each worker is located can be judged. And other modules are combined, so that mine operators can be positioned and monitored in the server 40, and the safety of the mine operators is guaranteed. Especially, when the gas in the mine exceeds the standard, whether the personnel leave safely can be monitored. The DMX controller may be connected to the server 40 through a network communication unit in the communication module 50, where the network communication unit may use TCP/IP; the DMX controller can also be connected to the miner's lamp through an RS485 communication unit in the communication module 50.
And S102, monitoring the gas concentration of the preset type of gas in the mine area, and controlling the mine lamp in the mine area to perform prompt operation when the gas concentration exceeds a preset concentration threshold value so as to prompt mine personnel to evacuate.
In this embodiment, the gas detection module 10 embedded in each mine lamp of the mine area or the gas detection module 10 independently installed in the mine is used for detecting the gas concentration of the preset type of gas in the mine area in real time, processing the detected data by the data processing module 20 in the mine to obtain the gas concentration, and then sending the gas concentration to the server 40, so that the server 40 can monitor the gas concentration of the preset type of gas in the mine area in real time, when the gas concentration exceeds the preset concentration threshold value in the server 40, the server 40 triggers the prompt information, and determines the mine with the gas exceeding standard through the address information of the gas monitoring module detecting the gas exceeding standard, so that the prompt information is sent to each mine lamp in the mine area, so that the mine lamp can perform the corresponding prompt operation. The prompt operation may be that each mine lamp in the mine performs alarm light display or sends out an alarm sound to remind the mine workers to evacuate, and the server 40 monitors the evacuation state of the mine workers to facilitate evacuation of better organization personnel and improve the evacuation efficiency of the mine workers.
Optionally, the miner's lamp includes a driving module 70, a light emitting module 80 and a control module 30: the server 40 can control the control module 30 to enable the control module 30 to send an alarm prompt message to the driving module 70, so that the driving module 70 drives the corresponding light in the light emitting module 80 to display, and thus the mine workers can quickly find the situation and evacuate.
Optionally, the server 40 may further generate control information according to the gas concentration in the gas distribution concentration map and send the control information to the control module 30, so that the control module 30 sends out the control information, and then the driving module 70 drives the light emitting module 80 to perform corresponding light display, so that the operator in the mine can determine the current gas concentration in the target area according to the corresponding light display, the server 40, by presetting a concentration range value in its interior, if the gas concentration in the target area is less than the above concentration range value, it indicates that the methane gas in the current target area is normal, control information is sent to the driving module 70 through the control module 30, so that the driving module 70 drives the light emitting module 80 to perform a green light display, the mine worker judges whether the current environment is normal according to the seen green light and continues working; if the gas concentration in the gas distribution concentration diagram is within the concentration range value, the condition that the methane gas in the current target area is about to exceed the standard is indicated, control information is sent to the driving module 70 through the control module 30, so that the driving module 70 drives the light emitting module 80 to display yellow light, and mine operators judge that the current environment is about to be unsafe according to the seen yellow light, and then evacuation operation is performed; if the gas concentration in the gas distribution concentration diagram is greater than the concentration range value, it is indicated that the methane gas in the current target area exceeds the standard, the control information is sent to the driving module 70 through the control module 30, so that the driving module 70 drives the light emitting module 80 to display red light, and the mine operators need to evacuate emergently according to the condition that the mine operators judge the current environment danger according to the seen red light. The light emitting module 80 includes an illumination light unit for illuminating each target area in the mine area, in addition to the light display for displaying the gas concentration.
Optionally, the miner lamp further comprises a voice alarm module 90; the server 40 can control the control module 30 to enable the control module 30 to send out alarm prompt information to the voice alarm module 90, so as to enable the voice alarm module 90 to perform voice alarm to remind the operating personnel in the well that the methane gas in the current target area exceeds the standard and needs to be evacuated immediately.
Optionally, as shown in fig. 4, the step S102 of controlling the miner lamp in the mine area to perform a prompt operation includes:

And S403, sending a preset control instruction to the miner lamp needing to be subjected to prompt operation in the mine area, so that the miner lamp is subjected to prompt operation according to the control instruction.
In this embodiment, because at least two pieces of channel information, channel information of an emergency refuge room and the like are generally set in a mine for facilitating evacuation in an emergency, when the gas concentration exceeds a preset concentration threshold, mobile terminal address information in an original address information set in the mine with an excessive current concentration needs to be obtained, that is, the position of a current mine operator in the mine is determined, escape channel information most suitable for escape of the mine operator is determined according to the channel information and the position of the current mine operator, a mine lamp on the escape channel, that is, a mine lamp to be controlled by a ground station is determined according to the mine lamp address information in the original address information set after the current escape channel information is determined, the ground station sends a preset control instruction to the determined mine lamp so as to prompt operation according to the control instruction, so that mine operators can evacuate and evacuate quickly according to the prompt operation of the miner lamp, the evacuation efficiency of the mine operators is improved, and the possibility of casualties is reduced. The prompt operation of the miner lamp comprises light display, voice prompt and the like.
Optionally, the monitoring of the gas concentration of the preset type of gas in the mine area in step S102 includes:
controlling a gas detection module 10 to emit laser at a preset position of a target area with preset type gas, so that the laser penetrates through the target area until the laser touches the edge position of the target area for reflection; the target area is an area obtained by dividing the mine area according to a preset rule.
In this embodiment, because the mine belongs to a dangerous operation occasion, especially, according to a dangerous situation caused by the increase of toxic gas in the mine, the gas detection module 10 may be set up in the mine gas monitoring system to perform gas detection on a part of the area in the mine, and the server 40 detects the laser passing through the target area where the preset type of gas exists by controlling the gas detection module 10 to determine each data information detected in the laser transmission process, so that the subsequent monitoring data processing module 20 determines the gas concentration in the current target area according to the obtained data information. Because the gas detection module 10 only detects gas in a certain area, at least two gas detection modules 10 are set up in the mine area of each mine according to a preset setting rule so as to more comprehensively detect the mine area, and the target area is an area which can be detected after the gas detection module 10 is set up in the mine area, so that the mine area can be divided into the target areas according to the address of the set gas detection module 10. The preset type of gas may be methane gas, and the embodiment will be specifically described with methane gas as a detection object.
It can be understood that, as shown in fig. 5, fig. 5 is a second structural schematic diagram of the mine gas monitoring system, and the gas detection module 10 may adopt a tunable laser, such as an indium gallium arsenic detector, carried on the surface of the miner's lamp housing. Therefore, the emitting unit 101 in the gas detecting module 10 is used to control the tunable laser to emit laser at a preset position of the target area, so that the laser passes through the target area until it touches a wall at an edge position of the target area, that is, a wall of the mine. Methane gas is capable of absorbing photons of certain wavelengths, such as 3.4 microns and 1.65 microns. While the optical power is highly attenuated when these photons of specific wavelengths that can be absorbed pass through methane gas. But there is substantially no light absorption at wavelengths slightly different from these light absorption peaks. Therefore, based on this light absorption phenomenon, the gas detection module 10 can detect methane gas in the target region through a tunable laser spectroscopy technique.
Moreover, by utilizing the fast tuning capability of the tunable laser source in the emitting unit 101, the laser wavelength is rapidly and repeatedly tuned on the selected gas absorption peak, and when the wavelength tuning occurs, the laser reflected back after passing through the methane gas is monitored by the detecting unit 102, and finally the power information in the laser transmission process and the distance information between the preset position and the edge position are determined, so as to provide data support for subsequently determining the methane gas concentration of the target area.
Acquiring power information in the laser transmission process and distance information between the preset position and the edge position; the power information and the distance information are information determined by the gas detection module 10 according to the reflected laser light.
And determining the gas concentration of the target area according to the power information and the distance information.
In this embodiment, the server 40 obtains power information and distance information between a preset position and an edge position during laser transmission, where the power information and the distance information are information determined by the detection unit 102 in the gas detection module 10 according to the reflected laser, the data processing module 20 set in the server 40 processes the data information sent by the obtained gas detection module 10, and uses a tomography algorithm to draw a spatial distribution of the position and concentration of methane gas in a target area, so as to obtain a gas distribution concentration map of the target area, and further perform comparison and determination according to the gas concentration on the gas distribution concentration map. The detection unit 102 may be a photodetector.
Optionally, after the server 40 obtains the gas distribution concentration diagram, the gas distribution concentration diagram is displayed, and meanwhile, detailed information such as the composition, the concentration, the mine number and the like of the current methane gas is displayed, so that ground workers can find problems in time and take corresponding measures. It can be understood that, in the case that the gas concentration does not exceed the standard, since the ground station monitors the gas in real time by controlling the gas detection module 10 and the data processing module 20 generates the gas concentration distribution diagram, the gas concentration distribution diagram is displayed in real time after the gas concentration distribution diagram is obtained, so that the ground staff can conveniently monitor the gas concentration distribution diagram displayed by the server 40.
Optionally, the gas detection module 10 further includes an optical collimating element 103 and an optical focusing component 104; the emission laser 105 emitted by the emission unit 101 in the gas detection module 10 is processed by the optical collimating element 103, and then emitted to a target area with methane gas 107 until the emission laser touches the mine wall 108, and the reflected laser 106 reflected from the mine wall passes through the optical focusing component 104 and then is sent to the detection unit 102. The optical collimating element 103 may be a straight-through optical collimating element, and the optical focusing component 104 is mainly used for collecting and focusing photons.
Optionally, the data processing module 20 includes a tomography calculating unit, and the data processing module 20 processes the obtained power information during the laser transmission process and the distance information between the preset position and the edge position through the tomography calculating unit set therein, performs tomography calculation, and further determines the gas distribution concentration map of the target region. It is understood that in this embodiment, the wavelength of the tunable laser source is adjusted to one of the absorption peaks of the methane gas, the wavelength of the methane gas is adjusted to the desired laser emission by the emission unit 101, the emission is reflected, the light absorption amount of the reflected laser is measured by the detection unit 102, and the integration of the path length during the laser transmission process is combined to obtain the concentration of the methane gas.
Specifically, the path length vector of methane gas is calculated from the detected data information, and the projection of the laser light reflected by the absorbed methane gas is expressed by the bolan-beer law, which is specifically as follows:
Id(v)=AIO(v)*exp[α(v)*2CL(θ)]
id (v) is a function of the power of the reflected laser light received by the detection unit 102 and the wave number v, where the power is W, and the wave number v is the reciprocal of the wavelength; a is the collection efficiency, i.e. the ratio of the power of the laser light reflected back received without methane gas to the initial laser power; io (v) is a function of the initial power of the laser beam emitted by the emitting unit 101 and the wave number v; α (v) is an absorption coefficient of methane gas when the wave number of the laser beam is v at normal atmospheric pressure; the above-mentioned CL (theta) is a methane gas path length vector traversed by integration in the process of emitting laser light emitted at an azimuth angle theta from the gas detection module 10 toward the mine wall, the azimuth angle being normally 90 degrees vertically, whereas L in CL (theta) refers to the range distance from the gas detection module 10 to the mine wall in m, and C in CL (theta) refers to the average concentration along the distance L. It will be appreciated that the gas path length vector CL (θ) in the above equation is a factor of 2, since the laser light is received after undergoing both transmission and reception between the gas detection module 10 and the mine wall.
The above formula is processed and transformed to calculate the length vector of the methane gas path which is passed by the laser emitted by the azimuth angle theta in the process of being emitted from the gas detection module 10 to the mine wall, and the formula after processing and transformation is as follows:
CL(θ)=-ln(Id(v)/AIO(v))/2α(v)
after the methane gas path length vector is obtained through data information processing, the tomography computing unit processes the obtained methane gas path length vector by using a tomography algorithm to obtain a gas distribution concentration map. Thereby determining the location, extent, and concentration of methane gas produced.
Specifically, the space between the gas detection module 10 and the mine wall is divided into grid cells 109 in advance, the space between the gas detection module 10 and the mine wall is a target area, as shown in fig. 6, fig. 6 is a third structural schematic diagram of the mine gas monitoring system, the grid cells 109 containing methane gas are determined by identifying non-zero methane gas path length vectors and intersection points of the grid cells 109, the existence of concentration conditions of the gas concentration of each grid cell 109 in the target area is determined by the above method, a binary methane gas map is established according to the existence of concentration conditions of each grid cell 109, and the binary methane gas map displays the position and the range of the processed methane gas. The binary methane gas map and the methane gas path length vector are used as input data of a tomography algorithm based on an algebraic reconstruction technique, and the average gas concentration of each grid unit 109 in the target area is determined, so that the gas distribution concentration map is obtained. The concentration measurement is more accurate by dividing the grid to obtain the gas concentration of each grid cell 109, and the smaller the above-mentioned grid cell 109 is divided, the more accurate the methane gas concentration determined by each grid cell 109 is.
Optionally, the judgment that the gas concentration exceeds the preset concentration threshold may be performed by comparing a target area with a data processing module 20 arranged in the server 40, the data processing module 20 judges the gas concentration of each grid unit 109 in the calculated gas distribution concentration diagram through a judgment and comparison unit arranged therein, if the gas concentration of one grid norm of the gas distribution concentration diagram is judged to be greater than or equal to the preset concentration threshold, it indicates that the methane gas concentration in the current target area exceeds the standard, and the judgment and comparison unit generates trigger information to prompt. Because the mine area comprises at least two target areas, the target areas can be compared and judged through one data processing module 20 to obtain a judgment result, and the mine area can also comprise at least two data processing modules 20 which respectively correspond to the gas detection modules 10 to obtain the judgment result.

In this embodiment, if the server 40 determines that the evacuation state of the mine workers does not conform to the preset evacuation state, for example, the mine workers in the mine with excessive gas are not all evacuated, the evacuation time taken for evacuating the mine workers, that is, the time for the mine workers to stay in the mine after the gas exceeds the standard, needs to be determined, where the evacuation time is a time difference between the time when the ground station controls the miner lamps in the mine area to perform the prompt operation and the time when the evacuation state is currently determined. If the evacuation time exceeds a preset time threshold, indicating that the operator who does not leave the mine at present is possibly dangerous, performing alarm operation so as to facilitate the monitoring personnel to perform corresponding rescue measures according to the alarm operation, for example, a ground station worker contacts with a staying operator by using a communication module arranged between a miner lamp and a ground station, or assigns a rescue worker or other workers in the mine to enter the mine to search for the staying mine operator after making safety measures; wherein the preset time threshold value can be any safe time length within 1 to 2 minutes.

By way of specific example and not limitation, during task operation, when one operator in the mine 1 leaves the mine 1 to reach another mine or chamber, the mobile terminal 60 carried by the operator who leaves will be wirelessly connected with the miner's lamp in the new area that is reached. For example, when a mine worker a1 arrives at a chamber, the corresponding mobile terminal a1 wirelessly connects with any one of the mine lamps F1 to Fn in the chamber, and a new address information set is generated:
