Illustrate specific implementation method below:
In the step 1, comprising:
Step 11: data collection steps.It is concentrated from initial data, following information is acquired to arbitrary point: being arrived in origin (warehouse)
Distance, at a distance from other points, arrival time the latest, the travel speed v of vehicle (all vehicle speeds are the same)；
When implementing, a view or table can be done in original database, it is assumed that the quantity of point is n, and the attribute of table includes:
Point id, initial point distance Li, the latest arrival time Ti are arrived, it will be in the information insertion table of n point.A n rank symmetrical matrix is made, the
I row j column storage the distance between point i and point j value Lij.Constant Vehicle Speed is v.Distance matrix is as follows:
Step 11: data dictionary design and Item Information acquisition step.According to storehouse management business record Item Information, such as
Production firm, date of manufacture, goods categories, packaging classification ....According to Item Information design data dictionary, classification point is such as packed
For case (outer packing, internal storage packet, single-item), packet (outer packing, inside include the single-item of label), single-item (single object
Product) ...；
When implementing, need for article to be divided into three case, packet, single-item ranks according to storehouse management.Single-item has the object of oneself
Product information and label；The outsourcing of packet is equipped with packet label, and the single-item labelled is placed in packet portion；Case outsourcing is equipped with case label, case
It is interior to place the packet labelled or single-item.Define data dictionary: tag types, type of items, vendor types, date of manufacture ...
Step 12:EPC coding step.EPC is stored in the area EPC of RFID label tag, EPC be label in systems it is editable only
One mark.Quick using RFID read-write equipment reading EPC most convenient, EPC is made of goods categories, supplier number, random number etc.；
EPC is produced according to EPC coding rule according to the relevant information of article；
When implementing, it is specified that EPC total length (byte number) such as 24 is, it is specified which data dictionary is each byte location value correspond to
The value or random number of definition.
Step 13: label type selecting and installation steps.RFID label tag is read and write vulnerable to external environmental interference, for different application field
There is the RFID label tag of all kinds of materials on the market in scape, such as: ceramic label, paper labels, anti-metal tag ....Selection is suitable
The label of material is fixed in the outer packing of case, packet or is fixed on the appearance of single-item；
When implementing, according to single-item, the outer packing material of packet, case, the label of suitable material is selected, such as: ceramic label, paper
Matter label, anti-metal tag ....Label is fixed on outer surface.
Step 14:RFID label system sends out step.According to storehouse management business demand, RFID label tag system is felt like jelly the man-machine friendship of part
The Item Information that mutual interface display needs to acquire, operator fill in Item Information, generate EPC code according to EPC coding rule, use
RFID read-write equipment is by the area EPC of EPC code write-in RFID label tag, by the area USER of Item Information write-in RFID label tag.Then lock
Determine the area EPC and the area USER is read-only；
When implementing, label preparation method software is developed, which provides human-computer interaction interface by operator's typing Item Information；
EPC is generated according to EPC coding rule and Item Information；It operates RFID read-write equipment and the area label E PC is written into EPC, article is believed
The breath write-in area USER；The area EPC of label, the area USER operating right are locked as read-only.
In the step 2, comprising:
Step 21: channel-detecting device subassembly selection step.Channel-detecting device component is divided into four major class: RFID read-write portion
Part, including reader, antenna；Cabinet shell component: since RFID is open read-write, to avoid reading other labels, shell
Cabinet uses electromagnetic screen；Industry Control host, including host and display screen；Transfer member, including conveyer belt, transmission move
Power device, electric control operation device；
When implementing, 4 port RFID read-write equipments and mating antenna are selected；Cabinet shell selects metal material, and built-in
Absorbing material；Industry Control Selection of chiller Linux system host, band network interface card, serial ports and respective drive, band touch display screen；
Step 22: channel-detecting device component installation steps.Channel-detecting device core is Air conduct measurement machine, by cabinet,
