Namely customer center is logistics management center, after receiving the next various information of official's label transmission, carry out the rejecting of bad data, carry out data processing, also by software algorithm, calculate the relative position distribution relation of all containers or counter, and it is visual, be presented on screen graphically, relative ranks align-err rate≤10
-4.Further, assign various operational order, state of goods is upgraded and issues.
Wireless Local Area Communication Networks location technology of the present invention, except utilizing Zigbee chip, can also utilize WiFi chip, Bluetooth communication chip; The orientation management of stock unit or goods can also be applied to except being applied to container, also can be applied to the goods orientation management in tiered warehouse facility.
5. due to sensing chip frequency and channel limited, so can disturb mutually when a large amount of sensing chip is communicated with, affect the normal reasoning of signal level, also can affect certainty of measurement, so the orderly radiation pattern in turn of node will be designed to.
If several fiducial mark check and punctuate can also be arranged on goods yard or shelf, as shown in Figure 8, just relative positioning can be become the absolute fix under a certain coordinate system.Fiducial mark check and punctuate can also round-off error, improves the positioning precision of container, counter.Like this, even if do not know the absolute coordinate position of each container or counter, also by its relative position distribution, namely can know each container or counter are at which row, which row, namely the present invention is in the similar mode to library management books, searches rapidly, exactly, calls and manage goods.
ZigBee technology, WiFi technology are a kind of emerging short distance, low rate radio network technique, between radio-frequency (RF) identification and bluetooth, can realize the sequence of user in indoor and locate.ZigBee technology, WiFi technology have oneself standard, only need little energy, by radio wave, data are passed to another sensing chip, so communication efficiency is very high from a sensing chip in the mode of relay.As: can reach tens meters the sphere of action of Zigbee sensing network, physical layer adopts spread spectrum, can resist interference to a certain extent, have response functions of retransmission.Primary bands and the modulation system of current ZigBee technology have:
(1) 868MHZ, transmission rate is 20KB/S, is applicable to Europe;
(2) 915MHZ, transmission rate is 40KB/S, is applicable to the U.S.;
(3) 2.4GHZ, transmission rate is 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, 2MHZ and 5MHZ, has 1,10 and 16 channels respectively.Although all employ Direct-Spread (DSSS) mode, spread spectrum and the modulation system of different frequency bands are had any different.
When Zigbee network is subject to external interference, when cannot normally work, whole network can dynamically be switched on another working channel.Meanwhile, energy consumption characteristics is a technical advantage of ZigBee technology.The application data rate that the node of usual ZigBee technology transmits is all lower, and when not needing communication, the node of ZigBee technology can enter the resting state of very low-power consumption, and now energy consumption only has the one thousandth under normal operating conditions; In the ordinary course of things, dormancy time accounts for the major part of total run time, and the time of normal work is sometimes less than one of percentage, therefore can reach very high energy-saving effect.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in scope disclosed by the invention; the change that can expect easily or replacement, all should be encompassed in the protection range of the claims in the present invention.
