Design And Implementation Of Intelligent Helmest System For Digital Mine

In China, the present situation of mining accidents frequently happening is one of the severe challenges in Safe Production Area. In terms of safety accident, metal and nonmetal mines ranks second in mining accidents, only after coal mine. The primary cause of frequent accidents in China is lack of advanced underground machinery and equipment, and many mines are still operated by hand. The second reason is the deficiency of necessary information construction of underground safety in our country, including imperfect environmental monitoring equipment, insufficient safety management system, backward communication equipment, insufficient deployment of six-main-systems, and so on. Recently, along with the development of information technology, the concept of digital mine has gradually been raised. Intelligence helmet equipment which can realize real-time monitoring of mine environmental and real-time communication plays a significant role in it. In this study, the research team has committed to developing the intelligent helmet system for mines, which combines integrated sensor technology, wireless communication techniques, optical fiber ring network technology, data mining theory, artificial intelligence, and virtual reality technology. It integrates the underground personnel with the intelligence helmet as a special mobile intelligent node, which combines the underground environmental data monitoring and real-time dual mode communication. Moreover, it also builds up an important part of underground Internet, and solves online detection and tracking problems, such as blind area production inspection, security monitoring and personnel status.The research on intelligent helmet system for digital mine mainly focuses on the detection of the mine environment, wireless communication, voice transmission, energy saving techniques, and so on. To achieve the intelligent helmet system, we need to utilize a touch screen to display environmental data, make phone calls, send text messages. Wireless communication module is implemented to transmit various terminal information to the underground station, and then to the central control room in turn. Warning module is used to raise the alarm when any detected environment data are out of the specified thresholds. Multi-sensor module is also built for collecting underground environment data, and the voice module used for handling the voice communication and text to voice communication. The central data processing platform is charge of processing all information in a centralized manner.
