Description

The utility model relates to mining, in particular to systems for monitoring, warning and determining the location of miners.

A device for wireless emergency call and information technology mine alarm and communication. The device comprises a transmitting kit installed on the day surface of the earth, consisting of a transmitter alarm generation and supply unit and a transmitting antenna connected to it with earthing switches, and receiving sets located in underground workings, which the miners are equipped with. The device operates on the principle of one-way radio communication between the ground transmitting and underground receiving sets. The disadvantages of this device is the lack of feedback between the underground and ground equipment, which does not allow to verify the reception of alert signals about the emergency situation for each miner (patent No. 2112146, E21F 17/18, Е21С 35/24 from 06/25/1993).

The well-known Talnakh complex [1] is the first Russian hardware-software complex based on a radiating cable, designed to build radio communication systems and automation for various purposes in the underground part of mines and mines (including dust and gas hazardous ones). The complex is designed to create a radio coverage area in underground workings. It is built on the basis of a radiating (radio emitting) cable, playing the role of an extended transceiver antenna. The composition of the radiating cable network, in addition to the cable itself, includes linear two-sided amplifiers that compensate for the attenuation of the radio signals in the cable. The Talnakh complex is designed to collect telemetric information about the operation of the radiating cable network, and to configure underground linear equipment. In addition, it allows you to determine the location of personnel and equipment in the underground part of mines and mines. Each miner and each piece of equipment whose location you want to control is assigned a subscriber device, which is a micro-computer controlled transceiver. The location of the complex subscribers is determined by linear readers installed in the mine workings, and the received data is transmitted to the server

positioning systems for building a database of the location of subscribers of the system. Access to the database is carried out from remote workstations of dispatchers or engineering and technical personnel using the local area network of the mine (mine), modem connections, or, if necessary, using the Internet. At workplaces, specialized software is installed. Information is presented both in textual and tabular form, and in graphic form on the plans of underground workings. The system allows you to take into account the operating hours of mine personnel underground and export data on the descent / ascent of employees to the database of the mine (mine). To account for the working hours of personnel underground, data is used from linear readers of the positioning system / time records. The system provides transmission of telecontrol (telecontrol) information by the mine controller of automated dispatch control systems at a speed of 64 kbit / s (intrinsically safe RS 485 interface). In the system, it is possible to organize data transmission channels with speeds of up to 8 Mbps. Talnakh was developed by the Russian company Information Technology Company CJSC. (Magazine "Fuel and Energy Complex" No. 12 2007).

The disadvantage of the Talnakh complex is the lack of independent monitoring of miners and monitoring the state of the surrounding mine environment, the system for generating alarm and warning commands for miners, and the ability to search for the location of miners by individual signals in case of an emergency.

Known automated control system and control of production processes, the environment and the location of miners in underground workings. The system carries out monitoring and control of technological processes in underground workings through wired and radio channels in automatic mode and upon request. The system is equipped with environmental sensors and coded signal receivers distributed in the underground mine, an information collection and transmission station, and a computer equipped with specialized software. In addition, each miner is equipped with a limited-range coded radio transmitter mounted in headlights. The positive effect of the system is based on the possibility of continuous monitoring of the state of the environment and the location of miners in underground workings by receiving and analyzing signals in computers coming from environmental sensors and encoded signal transmitters

miners. The disadvantages of this system is the passive mode of operation, which eliminates, firstly, the possibility of notifying each miner about the threat of an accident in generating and confirming the receipt of an alarm signal, and secondly, real monitoring of the evacuation process, due to the lack of feedback from the miner to the control computer . In addition, the limited range of encoded signal transmitters (as follows from the description in order to improve the accuracy of determining the location of a miner in normal operation) when a blockage occurs and a miner falls under it may not lead to a quick search for those in distress, since the thickness of the blockage can completely attenuate the signal transmitter (RF patent No. 2180941, E21F 17/18, Е21С 35/24 from 2000.02.25).

A known system for monitoring the state of moving objects and their movement. The system comprises a dispatch center and consumer equipment, including a navigation receiver with an antenna, a transceiver with an antenna, a keyboard and a modem connected to the transceiver, a video monitoring camera, an audio system, and a television monitor. The system includes an on-board computer connected to the processor, an analog-to-digital video signal converter and digital-to-analog audio and video signal converters, a storage device, a video monitoring camera and a television monitor. Security sensors are also connected to the on-board computer interface. The dispatch center is connected to consumer equipment through the antenna of the transceiver, via a radio channel. The power inputs of the navigation receiver, modem, transceiver, on-board computer, video surveillance camera, TV monitor and sensor protection are connected to an autonomous power supply. This system allows you to control mobile objects, its circuit solution allows you to quickly reprogram and change the order of functioning of the system units depending on the functions performed (RF patent No. 2122239).

The system has a complex configuration, which leads to a fairly high cost and operating costs. The preservation and analysis of images of protected objects is not provided.

A known system that contains a dispatch center and consumer equipment, including a navigation receiver with an antenna, a control video camera, an audio system and a television monitor, includes an on-board computer (US Patent No. 5,504,482)

The system also has a rather complicated configuration and does not allow monitoring to alert and determine the location of people in enclosed spaces.

The closest technical solution is the security system and monitoring of mobile objects (RF patent No. 2265531, B60R 25/00, G08B 25/10, 2003). The system comprises at least one video camera for receiving a video signal from a target, at least one device for receiving and transmitting a request signal, at least one computer connected via a local area network, transponders with their own identification signals, the total number of transponders equal to the number of proper owners, and each transponder signal identifies the proper owner, and the signal receiving and transmitting device is configured to receive the specified identification a code signal, at least one target detection sensor, which is used as a device selected from the group including infrared cameras, thermal imaging cameras, radar devices, motion sensors, at least one target recognition device connected via a hardware-software interface with said video camera, with a target detection sensor and with a transmit-receive device, at least one computer database with an identification signal pre-recorded in it at least one movable video camera adapted to aim at a target depending on the control signal received from the target recognition device and at least one observation terminal adapted to inform operator and receiving control commands from him. The database is configured to access it from a target recognition device, a moving camera and recording new information. The recognition device and the formation of control commands is performed with the possibility of: analyzing the signals received from the video camera, from the signal receiving-transmitting device and from target detection sensors; determining the target, calculating the velocity vector and the current coordinate of finding the target, recognizing an alarming situation based on them; target recognition in accordance with a given algorithm of information stored in the database; issuing an appropriate control signal to the mobile video camera for guidance on the target and an alarm signal to the monitoring terminal. The movable camera is configured to receive a video signal of an image of a target suitable for analysis and transmit it for storage in a database. A target recognition device configured to analyze a video signal from a video camera adapted to receive a video signal of a target in accordance with descriptions of an alarm situation selected from the group including brightness, size,

the length of stay in the controlled area, and the direction of movement, the number of people.

The disadvantage of using the well-known security system and monitoring of mobile objects in a mine environment is the lack of feedback from the monitoring terminal to mobile objects, that is, the possibility of independent monitoring of the mine background, recognition of emerging emergencies, warning and control of the evacuation of miners. Accidents in mines are characterized by unpredictable consequences of explosions, collapses, flooding. This will require not only fixing (according to monitoring data) the last location of the miners caught by the accident, but also their search in case of burial under the rubble. In addition, the emergency will require alerts to miners working in other areas not affected by the accident.

The technical task of the utility model is to create such a system that would ensure the safe work of miners in mine and mine workings, that is, with the ability to monitor the background situation in the mine, timely warning workers about emerging threats, control evacuation and search for those in distress.

The specified technical problem is solved due to the fact that in the well-known security system and monitoring of mobile objects containing at least one video camera, at least one computer, at least one signal receiving-transmitting device, connected via a local computing networks, as well as transponders configured to store and transmit their own identification code signals, and the total number of transponders in the system corresponds to the number of owners to be monitored ingu, and each transponder identification signal corresponds to a specific proper owner, the signal receiving and transmitting device configured to receive the specified identification code signal, at least one software recognition and generating control command in the computer, connected via a hardware-software interface with said video camera and a device for receiving and transmitting signals, at least one computer database with pre-recorded GOVERNMENTAL therein identification signals, subject to meeting certain owners monitoring alarm conditions described, at least one movable camera arranged to, depending on the guidance obtained from the sensing device and generating a control command

a control signal, and at least one observation terminal, adapted to inform the operator and receive control commands from him, at least one detection sensor associated with a recognition and generation of control commands configured to process received from the video camera from detection sensors, and from the transmit-receive device, as well as the ability to calculate the velocity vector and the current coordinate of the transponder owners to be monitored, as well as the formation and transmission and at least one movable infrared camera for receiving an infrared image signal, individual key fobs, the number of which is equal to the number of proper owners emitting individual beacon code signals, are inserted into the video camera through the serial communication channel of the corresponding control signal, issuing an alarm to the monitoring terminal acoustic, infrared and radio waves, at least one device for activating individual remote controls, at least one device recognition of an individual beacon code acoustic signal of individual key fobs, at least one device for recognizing an individual beacon code radio signal of individual key chains, at least one recognition device of an individual beacon code infrared signal of individual key chains, at least one smoke sensor, at least one , one methane sensor, at least one temperature sensor, at least one laser range finder, and smoke, methane and pace sensors The remote control, as well as the device for activating individual key fobs, are connected via a hardware-software interface via a serial communication channel to a recognition device and generate control commands, a movable infrared camera is capable of pointing, depending on the control signal received through a serial communication channel from a recognition and command generation device control, and in parallel connected to a movable camcorder.

It is preferable that the purpose of the video camera, infrared camera, location device, thermal imaging camera, motion sensors, smoke sensors, temperature and methane are the background parameters of the mine working, that is, temperature, concentration of methane and coal dust, the movement of coal seams. In the event that one of the parameters of the mine background does not correspond to the required one, the device data generates an alarm signal received via an electric line to the recognition and generation of control commands.

It is preferable that the movable video camera and infrared camera are configured to rotate in the vertical and horizontal planes and / or change the focal length and / or change the aperture and / or focus setting to provide guidance to the desired object.

It is preferable that the proposed system is characterized in that the algorithm for alerting miners is implemented as follows. When alarms occur, from detection sensors, hazardous (or potentially dangerous) areas of people’s stay are determined in the recognition and formation of control commands. For these zones, warning signals are generated in the recognition and formation of control commands, which, through the activation devices, include individual key fobs. When activating individual beacon code acoustic signals of individual remote controls, their owners must immediately leave the danger zone. The identification code of the transponders in the recognition and generation of control commands determines the appropriate owners who are or may be in a dangerous or potentially dangerous area, as well as the direction of their evacuation. Individual beacon code alarms for individual key fobs are received by individual beacon code recognition devices for infrared, acoustic and radio signals. Recognition devices for individual beacon code signals generate identification signals for miners by the individual emission of key fobs. Identification signals via the hardware-software (wired or wireless) interface are sent to the recognition device and the formation of control commands. These signals in the recognition device and the formation of control commands identifies and determines the location of miners and the direction of movement. Operational information on the state of the environment in potentially hazardous areas, the number and personnel of miners who find themselves in these areas, and the direction of their evacuation are received at monitoring terminals from a recognition device and generating control commands.

It is preferable that in the event of a blockage due to an explosion of methane or coal dust, the location and identification of distressed miners (buried under the rubble) will be carried out by direction finding based on the power level of the individual beacon code radiation of the key fobs in the acoustic, optical and radio wavelengths using recognition devices.

Advantageously, the recognition devices of the individual beacon code of the acoustic, infrared and radio signals of the individual key fobs have a weakly directed spatial reception pattern.

It is preferable that the radiation of individual key fobs is carried out at frequencies other than transponder emissions, and the radio frequencies and code signals of the radiation in the acoustic and infrared ranges of individual key fobs are different from each other.

Advantageously, the recognition and generation of control commands device is capable of analyzing data coming from methane, temperature and smoke sensors, a laser range finder, displacement sensors, a thermal imaging camera, location devices and an infrared camera,

Advantageously, the device for recognizing and generating control commands is configured to determine potentially hazardous areas for miners to stay and to send an alarm to the individual key fob activation device.

Advantageously, the recognition and generation of control commands device is configured to receive signals coming from the recognition devices of individual beacon codes of infrared acoustic and radio signals and to identify owners who are in a potentially dangerous area, as well as the direction of their evacuation.

Advantageously, at least one device selected from the group is used as a detection sensor — an infrared camera, a thermal imaging camera, a location device, and motion sensors.

A functional diagram of a mine alert monitoring and location system for miners is shown in FIG. The system consists of interconnected devices connected by wire or radio and combined into separate modules. This disaggregation into logical modules is conditional and does not impose restrictions on the essence of the invention.

Module 1 in the mine control zone is a set of detection sensors - devices implemented on various physical principles and monitors environmental habitability parameters. As such devices, a video camera 11 (for example, WAT-220), an infrared camera 12 (for example, TVC200 VL), a thermal imaging camera 13 (for example, IRTIS-2000), a laser range finder 14 (for example, DIMETIX DSL-AH-30) can be used ; motion sensor 15 (e.g. Infinite),

methane sensor 16 (for example, DMS-03), smoke sensor 17 (for example, TSD-90 A), temperature sensor 18 (for example, ATT-2508). Module 1 may include a different number and combination of the above devices depending on the specific mine plan and production conditions, with the possibility of mutual overlapping of the detection zones of the sensors. The main function of module 1 is to monitor the environmental parameters in the controlled area of the mine, and the issuance of alarms in module 2, in case the controlled parameters of the mine environment go beyond the established safety standards. The devices of module 1 are electrically connected to module 2, which contains a device for recognizing and generating control commands 21. (for example, based on a personal computer with an Intel Pentium processor). The device 21 is designed to recognize and generate control commands for miners warning devices and monitor the situation in the controlled area based on an analysis of the situation in the mine, measuring the coordinates and parameters of the miners' movement. The software of the recognition device and the formation of control commands 21 allows you to receive and digitize information from environmental monitoring devices in the control zone of mine workings, miners detection; analysis of individual beacon code acoustic, infrared and radio emissions of individual key fobs; memorize and monitor the state of the environment in the mine control zone (temperature, gas contamination, coal dust density, methane concentration); calculate the velocity vector, the current coordinate of the miner; give control signals to mobile video and infrared cameras, as well as activation devices for individual key fobs; issue alarms to monitoring, analysis of results and system control terminals; to identify miners by the signals of acoustic, infrared and radio emissions from remote controls; save recognized parameters to the database in a memory device. Module 2 is connected through an electrical interface to module 3 of the formation of video signals and infrared images of miners in the controlled area of the mine workings.

Module 3 includes parallel-connected movable video 31 and infrared 32 cameras controlled by control commands provided from module 2 via a serial communication channel. Control commands are generated using the software of module 2, and contain information about the velocity vector and the coordinates of the miner. Module 3 may contain a different number of movable controlled video and infrared cameras (for example, WV-CS 854 and JADE US, respectively) adapted to perform the following functions in accordance with

received by the control team from module 2: rotation in the vertical and horizontal planes; change in focal length; focus setting; Changing the aperture or shutter speed. Mobile video and infrared cameras of module 3 are connected through an interface with module 4, which is a computer with a storage device (for example, a personal computer).

Module 4 consists of a storage device 41. In this storage device 41 a database has been created with the possibility of storing: the time spent by all miners in the controlled area; individual beacon code signals emitted by individual key fobs in the acoustic, radio and infrared ranges in the event of an alarm; the state (parameters) of the mine environment in the control zone. Module 4 is electrically and logically connected through a typical program interface with module 2. Data is exchanged between modules 2 and 4. Module 4 is also electrically connected to the module 5 of the observation terminals, designed to analyze the results and control the system, including one or more terminals 51 of the observation. Monitoring terminals 51 are one or more personal computers connected by communication networks and designed to provide the operator with the ability to monitor what is happening in the control zone and control the monitoring system, alerts and determine the location of miners. The terminals 51 are configured to observe the situation on the screen and access the operator to control the system through a keyboard and microphone. Modules 2, 4, 5 can be made on the basis of a distribution network system, which is a combination of specialized computing devices and personal computers based on personal computers (for example, based on the Intel Pentium processor).

Module 6 consists of one or more transmit-receive devices 61, intended for transmitting request signals of the same structure, as well as receiving response identification code signals from transponders 71, combined in module 7. Transponders 71 are transponders with which proper owners are equipped - all miners going down to the mine. The transmit-receive devices are located along the mine workings and are electrically connected between themselves and the device 21. The transponder request and response zones are formed in such a way that one miner transponder can simultaneously respond only to the request of one transmit-receive device. Each transponder is adapted to receive request signals and transmit its own

response identification code signal to one or more transmitting and receiving devices 61. The own identification code signal is pre-recorded in the transponder. The distances between the transmitting and receiving devices, their sensitivity, as well as the radiation power of the transponders, are such that they provide, on the one hand, rather high accuracy of determining the location of miners, and on the other hand, a continuous tracking mode for miners along the entire network of transmitting and receiving devices.

Transponders, falling into the coverage area of the transmit-receive devices, receive a request signal and emit their own identification code signal. The transmit-receive device 61 receives the identification code signals from all transponders and transmits them to the recognition and generation of control commands 21 of the module 2.

In the recognition and generation of control commands 21 using the information stored in the database, all received transponder identification code signals are compared with those in the database. As devices for transmitting and receiving 61 signals, for example, EL-RFID-S from ELVIS [2] can be used. An ELVIS EL-RFID-T device may be used as a transponder.

The activation module for individual key fobs 8 consists of one or more devices 81 for activating individual key fobs. Activation can occur in two ways: automatically based on the alarms of one or more sensors of module 1, and on the operator’s command, based on the information displayed on terminal 51. Activation of key fobs can also come from the operator if the miners transponder for a long time time will not respond to the request signals of the transmit-receive devices and the location of miners will not be displayed on the operator’s monitor. In this case, the priority of issuing the activation command is given to the operator. In both cases, activation commands are received via an electric communication line to devices 81 from a recognition device and generating control commands. Activation commands are generated in the recognition and generation of control commands 21. Based on the analysis of the information received from modules 1 and 5, they are sent only to those key fobs whose proper owners are or may be in the danger zone. In this case, the device 21 generates a list of possible options and time for the evacuation of miners from the danger zone (s), as well as a list of miners who are in the danger zone, arriving at the monitoring terminal.

Activation devices 81 generate a radio signal for switching on individual key fobs 91 located in module 9. The appropriate owners — all miners descending into the mine — are equipped with individual key fobs. An individual key fob after activation starts emitting individual beacon code acoustic, infrared and radio signals, each of which is identified with its respective proper owner. The activation device is in electrical communication with the recognition device and the formation of control commands 21.

Individual beacon codes of acoustic, infrared and radio signals are received by recognition devices of individual beacon code radios 101, infrared 102, and acoustic 103 signals located in module 10. Recognition devices identify the respective owners by the parameters of individual beacon code signals and can have both wired and wireless communication with the recognition device and generating control commands 21. In the recognition device and generating control commands In the process of comparison, the received individual beacon code signals are compared with those available in the database. It is advisable to carry out an individual keychain 91 in one housing and in a single design with a transponder 71. Recognition devices are located in close proximity from the transmit-receive and activation devices of individual remote controls, therefore, the zones for generating interrogating and activating signals, as well as for receiving individual beacon code signals spatially coincide, and the frequencies of interrogating and activating radio signals differ.

It is preferable that all the devices of modules 1, 3, 6, 7, 8, 9, placed in the mine, are made with technology that can meet the requirements of intrinsic safety, explosion safety, fire safety, shock and moisture resistance.

In the General case, the alleged invention covers various options and combinations of software and hardware implementations of recognition and generation of control commands, observation terminals 51, transmit-receive devices 61, transponders 71, signal recognition devices of individual key fobs of module 10, as well as individual key fobs 91.

The principle of operation of the system is illustrated in the figure shown in figure 2., which shows an example of the implementation of the mine system. This example does not limit all possible construction options and essential features of a mine system

miners monitoring, alerting and positioning. The system related to a specific example includes ground (A) and underground (B) parts. The ground part includes an electrically connected observation terminal 51, a storage device 41 in which the database is located, and a recognition and generation unit for control commands 21. These devices can be implemented on the basis of a distribution network system, which is a combination of specialized computing devices and personal computers based on personal computers (for example, based on the Intel Pentium processor). The underground part consists of a set of detection sensors for monitoring the environment in the mine control zone, including a video camera 11, an infrared camera 12, a thermal imaging camera 13, a laser rangefinder 14, a motion sensor 15, a methane sensor 16, a smoke sensor 17, a temperature sensor 18; parallel-connected mobile video 31 and infrared 32 cameras; transmit-receive devices 61; devices for activating an individual key fob 81, recognition devices for individual beacon code radios 101, infrared 102, and acoustic 103 radiation signals of an individual key fob; located on the identified carrier (miner) of the individual key fob 91 and the transponder 71. Moreover, each environmental monitoring sensor 11-17, the transmit-receive device of the transmit-receive device 61, the activation device of the individual key fob 81, recognition devices 101, 102, 103, and mobile video 31 and infrared 32 cameras are electrically connected to the recognition and generation of control commands 21 via separate inputs 21. In addition, mobile video 31 and infrared cameras are connected via an interface to a storage device vom 41. Communication between the transponder 71 and the transmission-reception device 61, also the activation device 81, remote control 91 and the individual recognition devices 101, 102, 103, is set by the signals. Moreover, the radiation frequencies of the radio signals of the transponder and the individual remote control are different from each other.

The system operates in normal and emergency modes. The regular mode is the mode of everyday trouble-free production functioning of the mine. Emergency mode is a mode of emergency response, evacuation of miners due to a threat to their life and health.

In normal mode, the system carries out automated monitoring: the location of a miner equipped with a transponder 71 and an individual remote control 91 via radio line 19 as well as using moving video 31 and

infrared 32 cameras; the state of the medium in the production zone through detection sensors 11-17. Monitoring information is displayed on the screen of the terminal 51 of the operator.

In emergency mode, the system

registers alarms received from the detection sensors 11-17 to the recognition device and the formation of control commands 21;

transmits the activation signal of the individual remote control 91 from the activation device 81 via the radio line 20;

recognizes an individual key fob 91 using recognition devices 101, 102, 103 by individual beacon code radio 22, infrared 23, and acoustic 24 signals, respectively, and by the same signals it records the fact that the miner received an alarm signal;

controls the evacuation of the miner from the accident zone by means of request-response signals propagating along radio line 19, as well as using mobile video 31 and infrared 32 cameras;

searches for timely miners (due to death, injury or lost) who are in distress (under the rubble) of miners through signals 22, 23, 24 emitted by an individual keychain 91.

In normal mode, the parameters of the mine working environment are stable and do not go beyond the unacceptable threshold. Therefore, an alarm signal from the detection sensors 11-17 to the recognition device and the formation of control commands 21 is not received. An exchange is made on the radio line of the request-response 19 between the receiving-transmitting device 61 sending the signal of the general request and the transponder responding with a code identification signal. In the recognition and generation of control commands 21, according to the response signals, the current coordinates and the time of receipt of the response identification code signal, the motion vector are determined and the response signals of the transponder are identified with its proper carrier. Information from the recognition and generation of control commands 21 enters the database of the storage device 41, in which data on the location and direction of movement of the identified proper owner (miner) of the transponder 71 are accumulated. The information accumulated in the database is displayed on the screen of the terminal 51 and is updated with a period of sufficient to monitor the presence of a miner in the control zone, taking into account its mobility. The identified miner in the form of a corresponding mnemonic sign, in accordance with the coordinate information and the time of its receipt, is displayed on

the plan for the development of the mine, entered into the storage device 41. The system operator can, if necessary, obtain information about the route of movement of the miner.

The coordinates of the miner are transmitted to the movable video camera 31 and the infrared camera 32 in the form of a set of target designations taking into account the extrapolation of the movement of the miner. According to the target designation signals, the movable video camera 31 and the infrared camera 32 are aimed at the miner. The video and infrared image of the miner can be projected onto the screen of the terminal 51.

In the event that the parameters of the mine environment deviate from normal values that ensure vital activity, the detection sensors 11-17 are triggered and give an alarm. The reasons for the deviation of the environmental parameters may be an increase in the concentration of methane, carbon dioxide, coal dust, the appearance of smoke, fire, displacement of rock formations, stopping of main fans, etc. Since each sensor has a fixed location with coordinates associated with the mine plan, the recognition and formation of control commands 21 will give the coordinates of the alarm sensor indicating the type of alarm (for example, “FIRE”, “METHANE”, “EXPLOSION”). The computing device determines the size of the zones of possible damage and the direction and speed of movement of formations that threaten the life and health of people (smoke, gas, combustion products) and, via radio line 20, gives a signal to turn on the device 81 for activating an individual key fob 91 in areas of possible damage to miners. When the radiation of an individual keychain is turned on, the miner must immediately evacuate in the direction of exit. An individual key fob emits individual beacon code radios 22, infrared 23, and acoustic 24 signals that are received respectively by recognition devices of individual beacon code radios 101, infrared 102, and acoustic 103 signals. From the outputs of the recognition devices, the signals are sent to a special computing device for recognizing and generating control commands 21. From the database of the storage device 41, a selection of parameters of individual beacon code signals is received in the recognition and generation of control commands 21. In the device for recognizing and generating control commands 21, the parameters of the newly received individual beacon code signals are compared and identified with those available in the base of the storage device 41, as well as the coordinates and direction of the miner during the evacuation are calculated.

The time, direction of movement and the coordinates of the miner during the evacuation from the recognition device and the formation of control commands 21 are transferred to the base

data of the storage device 41. The receipt of signals from the recognition devices 101, 102, 103 in the recognition and generation of control commands 21 in itself is a feedback signal for receiving an alarm on an individual key fob. Moreover, the operator on the screen of the terminal 51 captures the time, coordinate, and direction of movement of the miner. Based on the signals of an individual keychain, the system of monitoring, warning and determining the location of miners searches and determines the location of miners in the event of a blockage and breakdown of the request-response system.

The system operator can instruct the system to monitor the selected miner, or a group of miners, indicated arbitrarily in the image. In this case, the system will automatically alternately display the images of miners transmitted by mobile cameras 31 and 32 in a detailed form.

The system is intended for use in the mining industry, using both closed and open miner mining methods for monitoring and ensuring the safety of miners. The system can be implemented both on the basis of specialized and on the basis of standard devices.
