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.
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...
There are many different factors that influence the safe production of coal mine such as equipment factor, environment factor and artificial factor etc. At current, many coal mines all over the world have built up harmoniously independent mutually monitoring and controlling sub-systems based on variety communicate channels and protocols. In this paper, a monitoring and controlling framework model...
Mine hoist is responsible for important tasks such as upgrading coal and gangue, lowering materials, lifting personnel and equipment. With increasing of mine depth and lifting capacity, multi-rope friction hoist becomes a key lifting equipment in major coal mines of China due to its advantages of small size, low weight, great lifting capacity, safe performance, suitable for deep well, etc.. As a large-scale...
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...
