Ordos Group: A new generation of all-digital AC servo control system

If you look closely, you can see that almost every advanced technology device with mechanical motion contains a numerical control system. Clothing machinery is certainly no exception.

Therefore, when Erdos CNC Technology Co., Ltd., a subsidiary of Ordos Group, the largest cashmere enterprise in China, held a press conference in Shanghai on September 20th, announcing that it owns 100% independent intellectual property rights, both hardware and software are independently developed and designed. When the new generation of JSA series full digital AC servo control system was born, as an industry, we realized that this is a boon for our textile and apparel equipment. Although its scope of application is far beyond the field of textile and apparel.

Premier Wen Jiabao pointed out in the National People's Congress "Government Report" in March last year that as a major developing country, China has weak scientific and technological capability for independent innovation, a serious lack of core technology, and more than 70% of car manufacturing, CNC machine tools and textiles. Machinery is occupied by imported products. The multiple areas of equipment mentioned in the report are based on two basic technologies. One is semiconductor chip technology and the other is digital control technology. As long as these two items go up and have their own core technologies, other problems will be easily solved.

In February of this year, the State stated in the Outline of the Medium- and Long-Term Scientific and Technological Development Plan that: “In the next 15 years, we will strengthen the capacity for independent innovation as the main line, and strive to build an innovative country as our goal, and we will improve our capacity for independent innovation as our national development strategy. All aspects of modernization should be implemented in various industries, industries, and regions so as to greatly improve the country's competitiveness."

China is a big manufacturing country and the market for CNC technology and textile machinery is very large. According to statistics, in 2004 China's total market sales of CNC machine tools exceeded 72 billion yuan, and imports accounted for about 2/3. In 2005, the total market value of China's textile machinery was RMB 30 billion, and imports also accounted for about two-thirds of the total; the total market for inverters and servo systems was RMB 15 billion, and imports accounted for more than 80%, showing that the market was large.

According to statistics, in recent years, China's annual imports of equipment account for about 10% of GDP, which means that it spends 1.8 trillion yuan to purchase imported equipment, of which at least 30% is related to China's numerical control technology. Only one of our Ordos Group's textile machinery and equipment imports amounted to several hundred million yuan.

In this computer era, computers use two types of users: one is the information function, that is, the ability of computers to calculate, store, and disseminate information. The network is a typical example of this; the other is the control function, that is, the computer passes a numerical control device. Turn its commands into real-world actions that cannot be done by human hands. It is the computer plus CNC equipment that makes large-scale automation possible. It can be said that CNC technology equals (computer + numerical control equipment).

The current CNC technology is based on an AC servo control system because it is fast, accurate, highly reliable, and relatively inexpensive. Therefore, it is the basis of all high-precision computer control systems and is the basis of modern advanced manufacturing. Its application range is extremely wide. For example: very popular CNC machine tools, based on the servo control system; another example is a high-level color printing machine, computer looms, precision packaging machinery, factory automation, and its basis is the servo control system. In addition to industry, each department of the national economy has extensively applied servo control systems, such as automatic control of subway vehicles, magnetic levitation vehicles, and automatic storage and transportation of food warehouses. Servo control system is not only widely used in various sectors of the national economy, but also widely used in national defense, space technology and other fields. It is clear that numerical control technology, especially advanced numerical control technology, has a strategic position that surpasses the general market value for a country.

There is no doubt that in the next few decades, it will be the digital control technology that has been exposed for decades.
For such important technologies, the state has listed high-end numerical control equipment and numerical control systems as major special projects in the “Eleventh Five-Year Plan” and the “Program for Medium- and Long-Term Scientific and Technological Development”.

At present, what is the domestic situation of CNC technology?
As a large developing country, China’s ability to independently innovate in science and technology is weak in some areas, and its core technology is seriously lacking.
In 2005, China’s machine tool import value was 53.1 billion. Why so much, mainly because of the backwardness of CNC technology supporting CNC machine tools, it seems that our machine tool export value is not too small. In 2005, it reached 52.3 billion but due to our The CNC systems used were outsourced and most of the profits went abroad. We only left some hard money.

The importance of number control technology to a country is so high that the highest CNC technology cannot be purchased with money. People are willing to sell you only second-rate, third-rate equipment, and first-class equipment will wait until they become second-rate equipment. sell to you.

Digital control technology, its most important core technology is digital motion control technology. The most advanced digital motion control technology is the various types of all-digital AC servo control system that we point out on the banner of the venue.

JSA series full digital AC servo system is a leading domestic product. It has the performance of the domestic similar products, it can automatically measure the load inertia, and then set the best parameters of the system, thus greatly reducing the technical requirements of the operator, and the system can still maintain the best performance, is currently The products with the highest accuracy and the widest range of speed in domestically produced control systems have a position control accuracy of 0.036 degrees, which has reached the level of internationally renowned brands. The speed range is 0.3 to 3,000 revolutions per minute, reaching 1:10000. For inertia above average, the low speed can reach 0.2 revolutions per minute, that is, a revolution of 300 seconds. It provides convenience for the user to use a larger inertia and expands the scope of use. The birth of JSA has reduced the development prospects for China-made high-performance CNC equipment in the future.

The success of its success will have a positive and far-reaching impact on China's CNC industry. After more than 20 years of development, Ordos has developed into a multinational enterprise group that combines cashmere, electricity, metallurgy, coal, chemical industry and a variety of industries. In the next 10 years, we will further increase investment in the field of numerical control technology. In order to promote China's CNC technology to enter the world-class level as soon as possible, and make unremitting efforts to enhance our core competitiveness.

From the very beginning of its establishment, Shanghai Ordos CNC Technology Co., Ltd. took the road of independent innovation and promoted China's CNC technology into world-class standards as its goal. The company's specific goal is "two years of China's first-class, five-year world-class, and strive to lead the world."

As the parent company of Shanghai Ordos CNC Technology Corporation, Erdos Group Corporation has the world's largest cashmere factory. In recent years, it has also successively developed the coal, chemical, ferrosilicon, and electric power fields and become a comprehensive group company.

The Erdos people in their short 20 years as their mission to revitalize national industries, under the guidance of the lofty ideals of “establishing national ambition and creating world famous brands” and the spirit of “corporate wisdom, boldness, pioneering, and innovative”, are hardly in Inner Mongolia. In the desert, from scratch, a miracle was established that was even more real than the city of Las Vegas in the American desert.
