Description
Technical field
The utility model relates to the ZigBee network field, specifically, relates to a kind of articles from the storeroom navigation system based on the ZigBee network.
Background technology
Zigbee is based on a low-power consumption territory fidonetFido of IEEE802.15.4 standard.Technology according to this agreement regulation is the wireless communication technology of a kind of short distance, low-power consumption.This title derives from the Eight characters dance of honeybee, since honeybee (bee) be by circle in the air and " drone " " dancing " of shaking wing to transmit pollen place azimuth information with the companion (zig), that is to say that the such mode of honeybee dependence has constituted the communication network in the colony.Be characterized in closely, low complex degree, self-organizing, low-power consumption, low data rate, low cost.Mainly be suitable for control and remote control field automatically, can embed various device.In brief, ZigBee is exactly a kind of cheap, the near radio networking mechanics of communication of low-power consumption.The network standard of ZigBee is responsible for formulation by IEEE 802.15 working groups, and Zigbee is the title of IEEE 802.15.4 standard in business promotion.802.15.4 the scope of application of standard press close to be produced very much and life, less demanding to data speed and Qos, and the target market is the field that industry, family and medical treatment etc. need low power consumption and low cost and large tracts of land to use wireless monitoring equipment.
The designer has made part Study in using based on zigbee before, design place once based on the humiture of zigbee detect, based on the warehouse temperature detection of zigbee etc.On this basis, based on zigbee apart from advantage with based on the range finding wireless sensor network location technology of RSSI, the warehouse logistics delivery management system based on zigbee is proposed.
The implementation close with the present invention
1, mine zigbee navigation system
The inner single line flow process zigbee location of using of mine, traditional mine safety way to manage lacks quantitative target, poor accuracy, the more and more needs of incompatibility modern production with artificial principal element.Short haul connection rising star Zigbee is applied to the mine safety field, propose a kind of assessment mode of qualitative, quantitative: the various parameters that adopt Zigbee that end sensor is collected reach the gateway on the tunnel, adopt again wired mode with the gateway transfer of data to ground central control computer, by computer data are analyzed comparison, the mine safety situation is made assessment.
2, mobile phone positioning principle
Mobile phone location is to utilize the cellular technology of GSM mobile radio communication to realize the inquiry of positional information, the gsm wireless communication network is to be made up by many residential quarters as the honeybee honeycomb to form, there is the numbering of oneself each residential quarter, just can know the mobile phone region by the identifier of residential quarter, mobile phone place.Still among improving, roughly about 200 meters, the suburb accuracy rating is roughly about 1000 meters-2000 meters for the urban district accuracy rating for mobile phone cell localization technology at present.
3, GPS navigation system basic principle
The basic principle of GPS navigation system is to measure the satellite of known location to the distance between the receiver user, and the data of comprehensive multi-satellite are just known the particular location of receiver then.Reach this purpose, the position of satellite can be found in satellite ephemeris according to the time that spaceborne clock records.The user then propagates into the time that the user experiences by the record satellite-signal to the distance of satellite, again it be multiply by the light velocity and obtain (because the ionospheric interference of atmosphere, this distance is not the actual distance between user and the satellite, but pseudorange (PR): when the gps satellite operate as normal, pseudo noise code (abbreviation pseudo-code) the emission navigation message that can constantly form with 1 and 0 binary element.The pseudo-code one that gps system uses has two kinds, is respectively civilian C/A sign indicating number and military P (Y) sign indicating number.C/A code frequency 1.023MHz, one millisecond of repetition period, intersymbol is equivalent to 300m apart from 1 microsecond; P code frequency 10.23MHz, 266.4 days repetition periods, intersymbol is equivalent to 30m apart from 0.1 microsecond.And the Y sign indicating number is to form on the basis of P sign indicating number, and security performance is better.Navigation message comprises information such as satellite ephemeris, working condition, clock correction, ionospheric delay correction, atmospheric refraction correction.It is that rectification comes out from satellite-signal, is modulated at 50b/s and launches on the carrier frequency.Comprise 5 every frame length 6s of subframe in each prime frame of navigation message.Each 10 character code of first three frame; Per 30 seconds repeat once, per hour upgrade once.Back two frames are 15000b altogether.Content in the navigation message mainly contains telemetry code, hand over word, the 1st, 2,3 data blocks, and wherein most important then is almanac data.When the user receives navigation message, extract satellite time and its clock with oneself is done the distance that contrast just can be learnt satellite and user, the present position when satellite almanac data in the recycling navigation message is extrapolated satellite emission text, the information such as position and speed of user in the WGS-84 earth coordinates just can be learnt.
The articles from the storeroom navigation system of prior art, spininess positions single line, can't position logistics in the zone; Cost is too high; Mobility is poor; Can not all be to use with the large-scale technology towards country, the masses towards the personal user.This is the deficiencies in the prior art part.
