Mine down-hole personnel Precise Position System based on the Zigbee full Wireless
Technical field
The utility model relates to a kind of mine communication technology, especially a kind of personnel in the pit's location technology, specifically a kind of mine down-hole personnel Precise Position System based on the Zigbee full Wireless.
Background technology
Zigbee is the synonym of IEEE 802.15.4 agreement, and the technology of stipulating according to this agreement is the wireless communication technology of a kind of short distance, low-power consumption.Zigbee and bluetooth are similar, are a kind of emerging short distances, the near radio networking mechanics of communication of low-power consumption.
Zigbee is a kind of highly reliable wireless data sending network, is similar to CDMA and GSM network.The Zigbee digital transmission module is similar to mobile network base station.Communication distance from the 75m of standard to hundreds of rice, several kilometers, and support infinite expanding.
Zigbee be one by a wireless data sending network platform that can how form to 65000 wireless data transmission modules, in whole network range, each Zigbee network digital transmission module quality inspection can be communicated by letter mutually, and the distance between each network node can be from the 75m infinite expanding of standard.
Different from the CDMA of mobile communication or GSM is that Zigbee network mainly is to set up for the transmission of industry spot automation data, thereby it has simply, and is easy to use, reliable operation, the characteristics that price is low.Each Zigbee network node not only itself can be used as monitored object, and for example its sensor values that connects directly carries out data acquisition and monitoring, and other network node of transfer passes the data information of coming automatically.In addition, each Zigbee network node (FFD) can also be in the scope that own signal covers, and a plurality of isolated child node (RFD) wireless connections of not bearing network information transfer task.
The technical advantage of Zigbee self has:
Figure DEST_PATH_RE-DEST_PATH_IMAGE001
Low-power consumption: under the low power consumption standby mode, No. 5 dry cells of 2 joints can be supported 1 node work 6～24 months, even longer.This is the outstanding advantage of Zigbee.Compare, bluetooth can be worked several weeks, and WIFI can work a few hours.
Figure DEST_PATH_DEST_PATH_IMAGE002
Low-cost: by significantly simplify agreement (less than bluetooth 1/10), reduced the requirement to communication controler, by forecast analysis, with 8051 8 8-digit microcontrollers measuring and calculating, Full Featured host node needs the 32KB code, the subfunction node is few to the 4KB code.
Figure DEST_PATH_RE-DEST_PATH_IMAGE003
Low rate: Zigbee be operated in 250kbps than low rate, 250kbps(2.4GHz is provided respectively) the initial data throughput, satisfy the application demand of lower rate transmissions data.
Closely: transmission range generally between 10～100m, after increasing the RF transmitting power, also rises to 1～3Km.This refers to the distance between adjacent node.If by the ability of route and inter-node communication, transmission range can be farther.
Figure DEST_PATH_RE-DEST_PATH_IMAGE005
Prolong in short-term: the response speed of zigbee is very fast, generally changes operating state over to from sleep and only needs the 15ms(millisecond), the node connection enters network only needs 30ms, has further saved electric energy.Compare, bluetooth needs 3～10s(second), WIFI needs 3s.
6. high power capacity: Zigbee can adopt starlike, sheet and mesh network topology, manages some child nodes by a host node.Maximum host nodes can be managed 254 child nodes; Colleague's host node can also by the last layer network node control, can form at most the large net of 65000 nodes.
Figure DEST_PATH_DEST_PATH_IMAGE006
High safety: Zigbee provides three level security patterns, comprises without security settings, uses access control inventory (ACL) to prevent the symmetric cryptography that illegally obtains data and adopt Advanced Encryption Standard (AES 128), to determine flexibly its security attribute.
Figure DEST_PATH_RE-DEST_PATH_IMAGE007
Unlicensed band.Adopt direct sequence spread spectrum in industrial science medical treatment (ISM), the 2.4GHz(whole world), 915MHz (U.S.) and 868MHz(be European).
The frequency band of Zigbee:
The 868MHz transmission rate is that 20KB/S is applicable to Europe.
The 915MHz transmission rate is that 40KB/S is applicable to the U.S..
2.4GHz transmission rate is the 250KB/S global general-use.
Because these three frequency band physical layers are not identical, channel width is also different separately for they, is respectively 0.6MHz, and 2MHz and 5MHZ have respectively 1 10 and 16 channels.
In Mine Personnel Positioning System, all based on card reader, identification card pattern, the development of this technology roughly is divided into the three generations to locate mode at present: closely manually swipe the card, remote passive discerning and remote initiative recognition.
The high and low frequency arrangement for reading was (such as mass transit card before first generation technology was mainly early, access card etc.) in the application of down-hole, because its reading range is roughly and leaves within the reader 20cm, so can only take the mode of closely manually swiping the card, the personnel that wear radio-frequency card must go forward just can be read near reader.Second generation technology is mainly based on main high frequency (433M, 868M, 915M etc.) application of arrangement for reading and passive RF card, its reading range can reach about 10 meters, generally take remote passive discerning mode, can solve the problem that the needs of the mode of closely manually swiping the card scan one by one.
Third generation technology is mainly based on the remote initiative recognition mode of wireless sense network frequency range (mainly being the 2.4-2.48G frequency range).This RM adopts the down-hole to dispose the mode of remote wireless communication network, so that the personnel that wear communication identification card in the down-hole as one of network node and the real-time communication of environment wireless network, transfer data information, this mode has changed the area positioning method of gate inhibition's formula fully, has realized the real-time location of exact position, down-hole.[0023] aspect route, Zigbee supports the route of the mesh network that reliability is very high, thus can arrange very wide network, and support multicast and broadcast characteristic, bring strong support can for abundant application.
