UA94533C2 - Method for operating beacon and rescue search equipment for searching miners under crump - Google Patents

Abstract

A method for operating the beacon and the rescue search equipment for searching the miners under the crump relates to the mine safety and may be used for locating the miners under the crump. The inventive novelty consists in providing the radio beacons for all the staff of the mine. The rescue group is equipped with the appliances for activation of radio beacons and the search devices. The appliance for activation of radio beacons is the source of the alternate low-frequency magnetic field with specified frequency and output. This magnetic field is detected by the coils with the ferromagnetic cores. When the threshold level is exceeded, the low-frequency magnetic field with another frequency is actuated for specified long-term interval. The search for the radio beacons is provided within this long-term interval. When the rescue and search operation fails within this specified long-term interval, another cycle of short-time actuation of the alternate low-frequency magnetic field with the first frequency follows. Then the search operation is resumed. Such mode of operating the rescue search equipment follows until the completion of the rescue operation.

On the one hand, this complicates the construction of operational objects (personnel and vehicles) for the Cydio beacon and makes its cost higher. On the other hand, our systems are carried out with accuracy, due to the simultaneous operation of the radio beacon for reception and the discreteness of the installation of the system readers, the transmission is associated with certain difficulties, the connection is actually 100-200 m. In addition to the mutual influence of the receiving and moreover, the system works only within the limits of direct transmission of the coils to each other, taking into account the bridge of the positioning object and the reader and practically the fact that the coils are in close proximity to each other in the event of a collapse of a mountain post. This, in its own way, which is an insurmountable obstacle for radio queues, also leads to the complication of the design and amplification of the signals adopted in the described systems, increasing the cost of the radio beacon.

At the same time, it is extremely necessary to effectively solve the problem of the mine personnel under the rubble, to solve the task of searching for the victims under the rubble - the mine worker is provided with a radio beacon, and we, having provided each mine worker, do not provide the search group with an expensive activation device, but a reliable radio beacon. Considering radio beacons and search devices. At the same time, until the search time can take from several hours, the composition of the activation device is introduced: the first gene- up to several days, reducing the energy consumption of the first low-frequency rotor, the first stationary activation device will significantly increase the effective- coil with a ferromagnetic core. The composition of the search for victims under the rubble, which is introduced before the radio beacon: immovable second and third coils, will allow to reduce the number of deaths among persons with ferromagnetic cores, narrow coal mines. second amplifier of the first low frequency, detector. The basis of the invention is the problem of delay, threshold device, second generator of the design of the radio beacon and reduction of the consumed low frequency. The composition of search devices and the energy of the activation device. It is solved depending on the tasks to be solved. is due to the fact that initially with help

According to the methods described, the problem is solved by the first low-frequency generator during the first generation of continuous low-frequency oscillations with a frequency of ii for a short period of time, and these continuous low-frequency oscillations with an oscillation frequency are applied to the terminals of the first stationary Im, and these oscillations are applied to the terminals of the first a coil with a ferromagnetic core and a radiating fixed coil with a ferromagnetic core and thereby emit an alternating magnetic field with a frequency thereby radiating an alternating magnetic field with The first coil with a ferromagnetic core of its frequency during a short period of time AI is placed in close proximity to the intended search object. The variable magnetic element of the activation device is placed in a field-free field with a frequency of n emitted by the first coil with an electromagnetic core in the medium proximity to the intended object, and the variable magnetic field with a frequency of the second fixed coil with a ferromagnet and caught by a second fixed coil with a core, which is installed in the radio beacon with a ferromagnetic core, which is installed in the search object. The signal that is removed from the terminals of the search object's radio beacon, after which the signal from the coils with a ferromagnetic core is amplified from the receiving terminals of the second coil with a ferromagnetic core in a narrow frequency band, is rectified and with a ferromagnetic core, amplified in a narrow one, its level is confused. When the rectified frequency is exceeded, its level is rectified and evaluated with a direct current signal of a certain threshold, and when the rectified signal level is exceeded, continuous low-level direct current of a certain threshold level begins to be generated for over-frequency oscillations with a frequency of u2, which are fed to the terminals with the help of a second low-frequency generator of a third stationary coil with a ferromagnetic Lee generator core, which is also placed in a radio magnetized by continuous low-frequency oscillations from the object of search, and radiated with the same variable frequency b, which apply to the terminals of the excitation of the same non-magnetic field with frequency b". The alternating magnetic field of the second fixed coil with a ferromagnetic core with a frequency of 2, emitted by the third receiver of the radio beacon, while the moving coil with a ferromagnetic core, the diomaka circuit of amplification and processing of signals with time-capturing coils with a ferromagnetic core is switched off in the mobile coil with a ferromagnetic core y she for a long period of time Л and nicks of search devices, and solve the problem thereby emitting a variable magnetic field from the search for a radio beacon or a person who is located at a frequency y" for a long period of time Л, under a pile of Prussian rock. at the same time, the continuous low-frequency signals produced by the first and second low-frequency D include a continuous low-frequency generator, make them close in frequency, the same oscillations with its frequency, which is connected to the same coil with a ferromagnetic core coils with a ferromagnetic core of a radio beacon from the side of its terminals of excitation, so that it is effective at both frequencies of it and r, while activating the radio beacon. In the radio beacon, after the end of a long period of time, the signal reception and processing path with its frequency is turned off again during a short period of time and the interval of time is turned off. At the same time, random activation emits alternating magnetic current low-frequency signals that produce a field with a frequency of and so on until all the search principles are even equal in value, which means that the measures will not be completed in full. are looking into the possibility of working a second immovable co-

A comparison of the invention with the already known spousals with a ferromagnetic core and the prototype shows that the method, which is claimed, is effective at both its and b frequencies. In the course of it continues, it reveals new technical properties that, during the entire time interval A, emit a variable consisting in the possibility of significantly simplifying the constant magnetic field with the frequency yg. This will change the magnetic position of the radio beacon and significantly reduce the consumption of the field with a frequency of 2, which is captured by the coils of the search-energy activation device. devices and carry out search activities during

These properties of the invention are new, because in the same period of time l. If during this period of time the prototype method, due to its inherent drawback, cannot complete the search activities, then what consists in the presence of two ferromagnesian coils for a short period of time Lin is included with a thin core in the radio beacon, the design of the activation device, after during which the diomayak turns out to be quite difficult. "Lee" is constantly searching. Such continuous radiation of an alternating magnetic field duration of actions continue until all search device activation provides significant consumption measures are not completed in full. energy from an autonomous power source. The specified way of functioning of the beacon and search equipment, which shortens the life of its equipment when searching for victims under continuous work, reducing the effectiveness of claims, can be implemented with the help of finding victims under rubble. In addition, the disorder shown in the drawing. The glass device is an intermittent reception of an alternating magnetic field from an activation device, a radio beacon, and at one frequency and continuous emission of an alternating magnetic field at a different frequency, while low-frequency oscillations 1 and 2, fixed radiating coils and receiving coils with ferromagnets, with ferromagnetic cores 3 and 4, narrow cores are located in the immediate bandpass amplifier of low-frequency signals 5, new to the design of the radio beacon, since in this search device 10.

At the same time, the generator of continuous lefts 5, the output of which is connected to the input of the rectifier of low-frequency oscillations with the frequency of its required 6, the output of which is connected to the input of the threshold auxiliary power, is turned on for a short period of time 7, the output of which is connected to the input time management Dean. The activation device is placed in the timer 9, while the output of the timer 9 is connected to the input of the low-frequency rescue measures control in the immediate vicinity of the venue. The radiation power of the generator 2 and with the control input of the narrow-band variable magnetic field should be sufficient for the low-frequency signal amplifier 5, while this variable magnetic field could be connected to the output of the low-frequency generator 2 by radio beacons located in the zone attached with the conclusions of the excitation of the stationary coil for carrying out rescue measures. In each of the beacons with a ferromagnetic core 4. this variable magnetic field is received and its level is evaluated. If this is exceeded, search for victims under the rubble, in this way. at the level of some threshold value in the radio beacon In a known way, timer 8 is started.
