Представленная на Фиг. Система шахтного позиционирования и оповещения устроена следующим образом. Presented in FIG. The mine positioning and warning system is arranged as follows.
В шахтных выработках, с системами позиционирования и оповещения установлены на определенных расстояниях друг от друга базовые станции 1 системы шахтного позиционирования и оповещения, каждая из которых снабжена антенной 2 связи, например WiFi. Мобильное устройство оповещения 3, содержащее блок экстренного автоматического голосового оповещения абонентов 11 , например для передачи сигнала о необходимости эвакуации, либо о завале, потере связи и т.л. Мобильное устройство оповещения 3 находится на экипировке работающего в выработке шахтера 4, перемещающегося по нижнему уровню шахтной выработки 5. Каждое мобильное устройство оповещения 3 связано, например через WiFi с несколькими (как минимум с двумя, а чаще всего с тремя- четырьмя) базовыми станциями 1. Базовые станции 1 связаны линиями связи 6 (например, проводными) с контроллером кластера базовых станций 7, причем контроллер 7 может содержать искробезопасный источник питания базовых станций 8. Каждое мобильное устройство оповещения 3 содержит антенну 9, также в каждом мобильном устройстве оповещения установлен блок определения места положения мобильных устройств оповещения относительно базовых станций 10. Дополнительно мобильное устройство оповещения 3 содержит кнопку экстренного оповещения 12, служащую для связи с диспетчером. В каждый кластер входит контроллер кластера 7 и до 12-ти базовых станций 1. Контроллер кластера базовых станций 7, через подземный 13 и надземный 14 маршрутизаторы (разделяемые на фигуре условной линией поверхности земли 15), связан с блоком формирования сигналов мобильных устройств оповещения 16, соединенного в свою очередь с сервером головного офиса 17, передающего информацию на компьютеризированные рабочие места 18. In mine workings, with positioning and warning systems, base stations 1 of the mine positioning and warning systems 1 are installed at certain distances from each other, each of which is equipped with a communication antenna 2, for example, WiFi. A mobile notification device 3, containing an emergency automatic voice notification unit for subscribers 11, for example, to transmit a signal about the need for evacuation, or about blockage, loss of communication, etc. The mobile warning device 3 is equipped with a miner 4 working in the mine and moving along the lower level of mine mine 5. Each mobile warning device 3 is connected, for example, via WiFi with several (at least two, and most often three or four) base stations 1 The base stations 1 are connected by communication lines 6 (for example, wired) with the cluster controller of the base stations 7, and the controller 7 may comprise an intrinsically safe power source for the base stations 8. Each mobile warning device 3 contains um antenna 9, also in each mobile notification device, a unit for determining the position of mobile warning devices relative to base stations 10 is installed. Additionally, the mobile warning device 3 includes an emergency notification button 12, which is used to communicate with the dispatcher. Each cluster includes a cluster controller 7 and up to 12 base stations 1. A cluster controller of base stations 7, through underground 13 and above ground 14 routers (separated by a conditional line on the earth’s surface 15), is connected to the signal generation block of mobile warning devices 16, connected in turn with the server of the head office 17, transmitting information to computerized workstations 18.
Представленная на Фиг. Система шахтного позиционирования и оповещения действует следующим образом. Подземная сеть заявляемой системы состоит из кластеров. В каждый кластер входит контроллер кластера 7 и, например, двенадцать базовых станций 1. Контроллер кластера базовых станций 7 обеспечивает создание проводных каналов связи с базовыми станциями 1, входящими в кластер, с другими контроллерами (не показаны) или маршрутизаторами подземной сети системы. Presented in FIG. The shaft positioning and warning system operates as follows. The underground network of the claimed system consists of clusters. Each cluster includes a cluster controller 7 and, for example, twelve base stations 1. A cluster controller of base stations 7 provides the creation of wired communication channels with base stations 1 included in the cluster, with other controllers (not shown) or routers of the system’s underground network.
Каждое мобильное устройство оповещения 3 (снабженное блоком определения места положения мобильных устройств оповещения относительно базовых станций 9) определяет уровень сигнала базовых станций 1 и по ним вычисляет свое местоположение. Предусмотрен и другой вариант: каждое мобильное устройство оповещения 3 (снабженное блоком определения места положения мобильных устройств оповещения относительно базовых станций 9) определяет задержку распространения сигнала от базовых станций 1 до этого мобильного устройства и по ней вычисляет свое местоположение. Таким образом, в режиме реального времени осуществляется мониторинг местоположения каждого шахтера 4, что позволяет, например, облегчать поиск людей застигнутых аварией. При отсутствии сигналов от мобильного устройства оповещения 3, местонахождение фиксируется по последним полученным координатам. Также в мобильном устройстве оповещения 3 предусмотрен «режим поиска», в котором периодически подаются короткие звуковые и световые сигналы. Кроме того, через мобильное устройство оповещения 3 происходит передача работающему шахтеру 4 аварийного сигнала, в частности о превышении опасного уровня загазованности, возникновения обрушений, нарушении энергоснабжения и т.п. Each mobile warning device 3 (equipped with a unit for determining the location of mobile warning devices relative to base stations 9) determines the signal level of base stations 1 and calculates its location from them. Another option is also provided: each mobile notification device 3 (equipped with a unit for determining the position of the mobile warning devices relative to base stations 9) determines the propagation delay of the signal from base stations 1 to this mobile device and calculates its location from it. Thus, in real time, the location of each miner 4 is monitored, which allows, for example, to facilitate the search for people caught in an accident. In the absence of signals from the mobile notification device 3, the location is fixed by the last coordinates received. Also in the mobile notification device 3, a “search mode” is provided in which short sound and light signals are periodically applied. In addition, an alarm signal is transmitted to a working miner 4 through a mobile warning device 3, in particular, when a dangerous level of gas contamination, collapses, a power failure, etc. are exceeded.
При необходимости установления связи с шахтером, диспетчер со своего рабочего места 18 может отправлять команду на соответствующее устройство 3. Оповещение выполняется при помощи голосовых фраз, заранее записанных в память мобильного устройства оповещения 3. При получении команды, устройство 3 автоматически отсылает пакет подтверждения о получении. Также, шахтер 4, получивший сигнал оповещения, дополнительно, нажатием на кнопку 12 на блоке экстренного оповещения головного офиса 11 , отправляет на компьютеризированное рабочее место 18 подтверждение получения соответствующей команды. В случае необходимости экстренного осуществления обратной связи, шахтер, например, троекратным нажатием кнопки 12, посылает посредством антенны мобильного устройства оповещения 9 на антенну базовой станции 2 сигнал, например посредством WiFi, на базовую станцию 1. Далее сигнал по линии связи 6 поступает через контроллер кластера базовых станций 7 If it is necessary to establish communication with the miner, the dispatcher from his workplace 18 can send a command to the corresponding device 3. The notification is performed using voice phrases previously recorded in the memory of the mobile notification device 3. Upon receipt of the command, device 3 automatically sends a confirmation packet of receipt. Also, the miner 4, who received the alert signal, additionally, by pressing the button 12 on the emergency alert unit of the head office 11, sends a confirmation of the receipt of the corresponding command to the computerized workstation 18. If emergency feedback is necessary, the miner, for example, by pressing the button 12 three times, sends a signal via the antenna of the mobile notification device 9 to the antenna of the base station 2, for example, via WiFi, to the base station 1. Next, the signal on the communication line 6 is transmitted through the cluster controller base stations 7
б на подземный 13 и далее наземный 14 маршрутизаторы. Далее сигнал через блок анализатора сигналов от мобильных устройств оповещения 16 поступает на сервер 17, передающий пакет с командой, на компьютеризированные рабочие места 18 и сообщающий диспетчеру о необходимости связи с данным шахтером 4. b to underground 13 and then ground 14 routers. Next, the signal through the block of the analyzer of signals from mobile warning devices 16 is sent to the server 17, which transmits a packet with a command, to computerized workstations 18 and informs the dispatcher about the need to communicate with this miner 4.
Также в случае обрыва проводной связи контроллера кластера базовых станций 7 и базовой станции 1 , связь между базовыми станциями 1 и между базовыми станциями 1 и контроллерами кластера базовой станции 7, может осуществляться на основе беспроводной связи. А также в случае обрыва проводной связи между контроллерами кластера базовых станций 7, связь между контроллерами кластера базовых станций 7 осуществляется на основе беспроводной связи. Also, in the event of a breakdown in the wired communication of the cluster controller of the base stations 7 and the base station 1, communication between the base stations 1 and between the base stations 1 and the cluster controllers of the base station 7 may be based on wireless communication. And also in the event of a broken wire connection between the cluster controllers of the base stations 7, communication between the cluster controllers of the base stations 7 is based on wireless communication.
Таким образом, достигается заявленный технический результат, а именно повышение точности и надежности определения местоположения работника шахты, расширение функциональности системы в организации автоматического оповещения шахтера внутри шахтной выработки при различных опасных случаях и осуществление с шахтными работниками устойчивой двусторонней связи, в то числе экстренной. Thus, the claimed technical result is achieved, namely, increasing the accuracy and reliability of determining the location of the mine worker, expanding the functionality of the system in organizing automatic notification of the miner inside the mine workings in various dangerous cases, and ensuring stable two-way communication with mine workers, including emergency communication.
