subject: Wu Di: Textile Information Contained In Course Of 30 Rain - Wu Di, The Digital Printing - Silk [print this page] "Some good project, good system because of technical brain drain, through the inspection identified, but to stop the run." Wu Di was very distressed, "The lesson should be well analyzed and summarized."
The early eighties, walking in the streets of Beijing, it is easy to find the clothes worn by the people there are only two colors? Blue and gray.
This to come to China's foreign guests were left a deep impression. Until now, many foreign guests also a clear description of the situation at that time the streets of Beijing.
Is, in those days, Wu Di from Tsinghua University, into the former Ministry of Textile Industry of the Computing Center, would then forged a bond with the textile industry.
"Plan" during the sowing
To the former Ministry of Textile Industry of the Computing Center, Wu Di of the oldest in the textile industry is on the computer control work.
Prior to this, the computer in the textile industry already has a number of applications.
Since 1979, the textile enterprises had applied to the production of computer, such as Shanghai China 22 Cotton Plant, Shanghai, Liu Chang part of the weaving machine loom to use computers to monitor domestic JS10. In 1980, the Textile Research Institute to use the computer for the Beijing National Cotton DJS130 three plants for laboratory data processing.
1982, the textile institute also uses the Z80 microprocessor imports of cotton country in Beijing with a cotton plant to develop computer software, and get a good promotion.
Wu Di recalled: "Computer applications in the textile industry, the earliest dating back to 1975, a Shanghai factory glove glove machine computer group control."
In the "Sixth Five-Year Plan" period, with the PC, SBC and other technologies, a number of pilot enterprises to start building the plant monitoring system and individual management information systems, such as a cotton factory and textile Beijing Design Institute, Beijing Textile Institute, Textile Research Institute and other units Cooperation , Developed a weaving workshop monitoring system, spinning plant monitoring system, a great impact.
Wu Di, said: "Although the 'June 5' during the computer in the textile industry are just some of the initial application, but played the role of computer applications enlightenment, sowed the seeds of information."
Early development of digital Printing "Plan", "August 5", the government introduced a major requirement for the state enterprises to upgrade more than two computer management companies must achieve. This aroused the attention of our government at all levels, the textile industry information has ushered in a period of rapid development.
1981, the printing specialist, Mr. Shum Lok Heng, author of the international emerging inkjet printing techniques are briefly introduced, raised some concerns the textile sector.
Textile research vice president at the time, well-known experts in the textile dyeing industry, Du Yan Sun and Automation Leader, automatic controls Wuxiong Min Rui felt the development prospects of this technology, the initiative to "spray printing technology and equipment research "subject.
Di Wu is proud to say, "I participated in the topic, is responsible for the computer control system and software development."
In a large amount of patent literature, the topic group learned Zimmer major international companies, three companies have similar products for carpets, textile printing blankets, sprinkler key technology mechanical type, continuous jet.
"Column title, we reckoned, the inkjet printing (Jet-inkPrinting) translated spray printing, now seems very accurate. The technical program is the most innovative design ideas on the nozzle. According to dyeing Technical adaptability requirements, electronic technology trends and possible mechanical processing capacity was determined using piezoelectric ceramic nozzles Vibration Control, on-demand jet way. nearly two decades spray printing technology is the development of this direction , confirmed the program very forward-looking. "said Wu Di.
Issue basically completed in 1984, including the pattern input system, computer control systems and prototype spray printing, using cationic water-soluble dye, printed carpets, blankets, towels and other fabric samples, the second year through the identification of scientific and technological achievements.
But indeed regrettable that, after the technology failed to identify further research, not applied in the production enterprise promotion.
"A technical analysis, the main problem is that heads off processing technology, however, can not guarantee consistency, reliability and continuous production requirements. In addition, the process failed to good control of the penetration of dye can not be used for thin fabrics . limited to the capacity of single board computers at that time, pattern control is trapping methods. "Di Wu pointed out the technology at a problem.
Wu Di very sorry to say: "It now seems that as technology development, pattern processing, control systems, printing and dyeing process problems can be solved in further development and improvement."
Differ greatly with the International 1986 Di Wu went to Germany to learn computer software, the situation abroad, remember him very deeply.
Germany, the United States, Japan and other countries of the textile industry began to develop in the direction to the continuous emergence of fully automatic spinning workshop, 10,000 spinning spindles and employment is only 30. The most advanced of about 60 to 70 people, most of them are 250 to 300.
Wu Di was to visit a German medium-sized woolen mill, the plant called Otten, including a spinning, weaving, dyeing and other processes of wool textile enterprises complete. The plant uses German Aojia (OrgaSystem)'s TEXIS comprehensive information management computer software.
TEXIS is the application of MRP principles and methods of commercial software, its factory sales, production planning, scheduling, inventory, purchasing, shipping and financial to integrated management and CAD systems can be connected to fabric, using the profits to improve after 5%, benefits are substantial.
At that time, most information technology start-up companies, established systems are using PC-DOS systems and Dbase , development is more laborious. Importantly, despite the joint of the net, but the database is not centralized, much less distributed. In Europe and the United States, then applications have reached a higher level.
And "China Computer Users," for some edge
1986, the State Science and Technology in the deployment of the "Plan" research program, for the first time included in the textile industry of computer automatic control system and management system.
The same year, Wu Di and colleagues share in the "Beijing No. 3-pin computer-assisted business management and control system" of national projects. "It was a great feeling pressure." Wu Di said, "but also very passionate, must bring good things to do
