The difference between the current development status and future development trends of Ningbo Hongde Technical Research Training Center) and the development status of Ningbo Hongde Technical Research Training Center It has developed to the current microcomputer composed of bit and bit microprocessors, and has realized multi-channel processing of multi-processors. Today, the technology is very mature. Not only have the control functions been enhanced, power consumption and volume reduced, costs reduced, reliability improved, programming and fault detection more flexible and convenient, but also with the development of remote/communication networks, data processing and image display. The development has led to the development in the direction of continuous production process control and has become a major pillar in realizing industrial production automation.
Nowadays, there are many manufacturers in the world, and their products are of various types. According to regions, they can be divided into three genres: the United States, Europe, and Japan. The products of each genre have their own characteristics. Among them, the United States is a major manufacturing country with many manufacturers, the famous ones include Company B, General Electric Company, and Modicon (MD) Company. The main manufacturers of European products include Germany's Siemens (M), the company, and France. There are many manufacturers in Japan, such as Mitsubishi, Omron, Panasonic, Fuji, etc., and South Korea's Samsung (M), etc. The products of these manufacturers account for more than 1% of the market share.
After years of development, there are about 30 domestic manufacturers, and the domestic application market is still dominated by foreign products. Domestic companies have greater competitive advantages when conducting business, such as: demand advantages, product customization advantages, cost advantages, service advantages, and response speed advantages.
), the development trend
As the application fields are expanding day by day, the technology and its product structure are constantly improving, the functions are becoming more and more powerful, and the cost performance is getting higher and higher.
In terms of product scale, it is developing in two extremes. On the one hand, vigorously develop small and ultra-small products that are faster and more cost-effective. To meet the needs of stand-alone and small automatic control. On the other hand, it is developing towards a large-scale direction with high speed, large capacity and perfect technology. As the requirements for complex system control become higher and higher and microprocessor and computer technology continue to develop, people have higher and higher requirements for information processing speed and require larger and larger user memory capacity.
, Developing towards communication network
Network control is the current trend in the development of control systems and technologies. Network communication between the computer and the host computer has been widely used. Currently, manufacturers are developing their own dedicated communication modules and communication software to enhance networking capabilities. Various manufacturers are also negotiating to specify common communication standards to form a larger network system. It has become an indispensable part of the distributed control system (D).
Developing towards modularization and intelligence
In order to meet the needs of various control systems for industrial automation, manufacturers have developed many new devices and modules in recent years, such as intelligent/modules, temperature control modules and Special intelligent modules specially used to detect external faults, etc. The development and application of these modules not only enhance the functions, expand the scope of applications, but also improve the reliability of the system.
Diversification and standardization of programming languages and programming tools
The coexistence, complementation and development of multiple programming languages is a trend in software progress. While manufacturers are making hardware and programming tools frequently updated, diversified, and functionally improved, they are increasingly moving closer to M (Manufacturing Automation Protocol), using basic components including input and output modules, communication protocols, programming languages, and programming tools. Normalization and standardization.
