In this paper the necessity to apply Internet of Things (Hereinafter referred to as IOT) in the coal industry is analyzed. The architecture of a new kind of IOT for coal mine and its main technical indicators are proposed based on sensor technology, combined with Industrial Ethernet, 3G/WIFI wireless networks, wireless sensor networks and other technologies.
Safety is an element of extreme priority in mining operations, currently many traditional mining countries are investing in the implementation of wireless sensors capable of reducing the number of accidents; through early warning signs to prevent injuries, dead and significant economic losses. The application of sensors capable of measuring in real time variables of interest, promises to be of great...
RFID is a non-contact automatic identification technology that uses radio frequency signals automatic recognizes target and access to relevant data. The identification work does not require human interference and can work in variety of harsh environments. But if there is no network to transmit data, it will be difficult to play its advantage. Under the influence of environmental conditions, the traditional...
This article describes the design of a wireless sensor network based on ZigBee technology. It is mainly used for collecting and transferring the various monitoring information about the coal mine underground. Then the data will be analysed and processed in the monitoring system outside, so that we can ensure the safety of the coal production and effectiveness better.
For the purpose of enhance the security of poor working in coal mine, it's important to study on the problem of location and tracking for keeping mining personnel and down hole equipments safe. We put forward wireless sensor network underground location algorithm which is based on the superposition of RSSI and DV-Hop. This algorithm makes up for the shortage of RSSI algorithm and DV-Hop algorithm...
A cost effective ZigBee-based wireless mine supervising system is presented in this article. This scheme used intelligent helmets as voice terminal and ultra-low-power nodes of wireless sensor network.The programme adopted ZigBee wireless technology to build wireless sensor networks, realized real-time surveillance with early-warning intelligence on methane, temperature, humidity in mining area, and...
In recent years, coal mine accidents have happened frequently in our country. These bring high casualties and huge economic losses, and ring the alarm bell for our coal industry. The traditional coal mine gas monitoring system uses the method of wire network, because of the restriction of time and space flexibility in the wire network, it is impossible to build a wire system in short time. For real-time...
