Concrete application example two：One color mark is specified using color data internet management method and system of the present invention
Standard, sets hunting zone, internet carries out color search automatically.
(1) standard of color search, color a are transferred from color data internet platform:100/2BL193219
(2) setting light source for searching is：D65-10 light sources, search condition is DEcmc:1.0 (explanations：This is set as searching for face
Data of the different size of aberration in the range of 1.0), system is automatically using color a as standard, and search is contrasted with color a, colour-difference
Similar color in the range of different DEcmc numerical value≤1.0, for example, finding color b in stock.
| Title | Type | DEcmc |
| Color a:100/2BL193219 | Standard | / |
| Color b:100/2BL174619 | Phase advancing coloud nearside | 0.36 |
System carries out the color distortion end value project that automatic display color a is compared with color b：DLcmc、Da*、Db*、
DCcmc、DHcmc、DEcmc。
(4) color a is searched, and satisfactory color has：Color b, its search result is given birth to aberration result auto-returned
Production system specified location：Color b:100/2BL174619DEcmc values：0.36 color meets the color requirement of (2) setting, judges
As a result it is:PASS, " whether reuse " column is returned using result " √ "；Production, color b are notified simultaneously:100/2BL174619 can be with
Replacement color a:100/2BL193219 carries out following process, meanwhile, system cancels color a automatically:100/2BL193219 life
Produce processing arrangement.
Application example three：Realize that white yarn yarn production is real-time using color data internet management method and system of the present invention
Let pass.
(1) white yarn data are uploaded into Web platforms from each port, it is necessary in use, from color data internet platform,
Transfer white yarn d:(this transfers process and can be understood as directly obtaining from color data internet platform ZC020519 data
The data calculated), it is such as shown below：
(2) production system captures white yarn d automatically from color data internet platform:ZC020519 data, are put into production
In system at demand position, the white yarn d in system searching backstage:ZC020519 is corresponding to control clearance Rule of judgment to be Whiteness:
Between 153~157, existing white yarn d:ZC020519 Whiteness:：153.66, in acceptability limit, production system is entered automatically
After row judges, clearance result is provided, " √ " is beaten in systems, confirm that this white yarn can let pass shipment.
Using color data internet management method and system of the present invention, multiple color device ports can be collected automatically
Color Reflectance data, are calculated the data item that color world one is example, while linking creation data, are placed on public face
Chromatic number is according to internet platform；On the basis of calculating, it can not only realize, color a and the man-to-man color distortion ratios of color b
Compared with；Can also be to multiple colors：Color a, color b, color C ... colors n carry out one-to-many color distortion and compared.Pass through face
Color is calculated, compared, the application in terms of quality control, color production clearance, color storage discoloration to produce color etc. color
Carry out automatic management and control.Furthermore it is also possible to define random color standard, set after search color condition, scan for, search close
Color, while be connected with production system, check whether to measure in stock to reclaim and use, so that quantity in stock is reduced, carry
High stock's usage amount.
Color data internet management method and system of the present invention, in production, the control (including white) in terms of color
Judged, controlled, trend, follow up simultaneously apply in real time, production scene is informed in real time, the color distortion size in production, in real time
Judge that produce color tells whether the color for judging production meets the requirements of the customers whether in the range of coloration compliance, in real time, can
It is automatic to let pass, it is desired nonetheless to continue with, follow up, the influence that artificial subjective factor is judged production clearance is reduced, while real
Show the real-time combination of color data and creation data, most importantly breach the limitation such as board, space, personnel, equipment, it is whole
Color resource has been closed, color big data has been realized and shares.
Above example only expresses the several embodiments of the present invention, and it describes more specific and detailed, but can not
Therefore it is construed as limiting the scope of the patent.It should be pointed out that for the person of ordinary skill of the art,
On the premise of not departing from present inventive concept, various modifications and improvements can be made, these belong to protection scope of the present invention.
Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
