Description

A kind of unmanned electric locomotive wireless communication system of mine
Technical field
The invention belongs to mine rail travel technical field, the unmanned electric locomotive wireless communication system specifically used in a kind of mine laneway.
Background technology
Mining industry is that current domestic mining is relatively backward, particularly the Mining Transport of down-hole Ore, is mainly manifested in work under bad environment with mineral resources for producing the ancient industry of object, and technical equipment falls behind, and user of service is more, and conevying efficiency is low. Digitized, informationization, unmanned, intelligent and lasting exploit are the Main way of current mine development. Ore Transportation ability, efficiency and safety, as one of the key project of underground mining winning system, along with the increase of mining difficulty, are had higher requirement by Ore Transportation.
Rail electric locomotive is the Ore Transportation instrument that current mine is the most commonly used, Remote and unmanned, intelligent be the Main way of following Ore Transportation. Realizing a unmanned prerequisite of mine rail travel is to realize the wireless signal all standing in mining conveying tunnel, namely sets up reliable and stable data link between ground central station of floating dock and unmanned electric locomotive.
Conventional wireless communication technology includes the polytypes such as WiFi, 3G/4G communication, ZigBee, bluetooth, data radio station. Wherein WiFi full name WirelessFidelity, is wireless technology standard currently mainly, and initial specification proposed in 1997, had developed IEEE802.11b/g/n multiple wireless protocols later successively. WiFi can be completely compatible with Ethernet, thus realizing being directly connected to of WLAN and Ethernet, and the relevant product of WiFi is numerous, and networking is convenient, reduces the cost of network configuration, and possesses extensibility flexibly, supports that the terminal of different system accesses. WiFi power consumption is relatively low simultaneously, has the advantage that transmitting power is little, and safety is of a relatively high. WiFi supports the data service of high bandwidth, and up-to-date 802.11n supports 300,000,000 bandwidth, it is possible to transmission includes the various data signals of high-definition video signal.
The operation of the unmanned electric locomotive of mine, it is necessary to cordless communication network covers running region, using as the data channel between locomotive and central station of floating dock. WiFi has incomparable advantage relative to other communication, and based on this, the present invention proposes a kind of wireless communication system suitable in unmanned electric locomotive underground communica tion.
Summary of the invention
The present invention proposes a kind of wireless communication system suitable in the unmanned electric locomotive of mine. This communication system based on TCP/IP procotol and IEEE802.11b/g/n wireless communication protocol, set up with industry ethernet ring network for backbone, with WiFi wireless network for extend network structure. Ethernet ring network is set up between ground central station of floating dock and mine laneway, some WiFi wireless base stations are set in underworkings, form the mode that cable network combines with wireless base station, realize WiFi signal and cover region, whole tunnel, WiFi wireless terminal is installed simultaneously on unmanned electric locomotive, set up wireless connections with the WiFi base station in tunnel, again through cable network, between ground central station of floating dock computer and electric locomotive Vehicle Controller, set up reliable and stable data link.
WiFi signal has anti-interference preferably and reflection, refracting power under mine. By reasonably arranging WiFi base station location and direction, it is possible to achieve the wireless signal all standing of unmanned electric locomotive working excavation. Communication system mainly includes the equipment such as switch, wireless base station, car wireless terminal, power supply. Whole communication system is made up of two parts:
Part I: administrative section. By being arranged on the network management computer of ground central station of floating dock, it is achieved network configuration, and to the monitor in real time of each link of communication system and management. The capital equipment comprised is the corollary equipments such as network management computer, the network management software and ups power.
Part II: tcp data segment. Tcp data segment is mainly made up of switch, radio communication base station, car wireless terminal, field power supply etc.

Detailed description of the invention:
The network topology structure of communication system is to arrange a core switch supporting three layers dynamic routing function at ground central station of floating dock. The network management computer of ground central station of floating dock, server etc. all access core switch. Core switch is connected with underground site switch by optical fiber, WiFi wireless base station accesses underground site switch by Ethernet mode, can dispose and tunnel distribution situation according to underground site switch, adopt arrangement flexibly, it is achieved the WiFi signal of underworkings covers. Underground equipment passes through exchange interface access network based on ethernet nearby. Operator station is set in down-hole, underground equipment and network can be carried out situ configuration, inquiry.
The layout of whole communication system divides aboveground and Liang Ge region, down-hole. The equipment such as ground central station of floating dock configuration network management computer, core switch, ups power. Underground part needs to install some field exchange machines, radio communication base station, power supply box according to scene; Power supply box is arranged on around base station nearby, and every field power supply case provides power supply for a stylobate station.
Preferably, communication media among the switches adopts single-mode fiber, adopts super Category-5 twisted pair between switch and wireless base station.
Adopt the mode that beam antenna and omnidirectional antenna combine to realize wireless signal to cover. Based on beam antenna in the basic principle Shi Zhi lane that node antennas is arranged; In traffic intersection and corner, omnidirectional antenna has better signal coverage rate, thus it is main for adopting omnidirectional antenna. During actual implementation WiFi wireless network, by in-site measurement wireless signal strength to the position of each node, antenna type, be adjusted towards with quantity, the signal coverage areas appropriateness making adjacent two WiFi base stations is overlapping.
