2.2 Technological development gap of automation industry at home and abroad

1) Gap in innovation ability :(1) Lack of original high technology achievements. Domestic automation industry related enterprises often through the introduction of foreign advanced technology to promote the upgrading of products, but it is difficult to thoroughly absorb foreign technology, often fall into the “backward – introduction – backward” state of development, lack of their own innovation ability, is not conducive to the development of domestic technology; (2) Lack of innovative ideas. At present, most domestic enterprises invest less than 2% of their income in product research and development, while foreign research and development expenditure accounts for about 8% of their income. As a result, domestic product research and development departments are underfunded, which seriously affects their research and development ability, resulting in insufficient innovation. (3) Differences in external market environment. Most domestic enterprises do not understand the level of domestic technology, distrust, but to foreign products too favor, always hold a skeptical attitude to domestic products, dare not use domestic products, so that domestic instrument is difficult to enter the high-end domestic and foreign markets, affecting its development.

2))Product quality gap :(1) poor safety and reliability. At present, there is still a certain gap between the safety and reliability of domestic products and foreign products, and the safety and reliability index of domestic and foreign products is roughly 2 levels. (2) Great performance difference. There is a difference of one level in the accuracy of existing automatic instrument products at home and abroad, and there is also a certain gap in their intellectualization and digitalization.

3.1 Intelligence

With the development of industrial automation, intelligence is becoming more and more important, in the past control algorithm, only by the regulator or DCS to complete, but now only intelligent controller can autonomously adjust, reduce the burden of DCS, improve its work safety and reliability, Therefore, intelligence is the development trend of automatic instrument and control technology.

3.2 Networking

Through the application of computer digital communication technology, it can make the combination of automatic control system and automatic instrument, greatly improve its connection, to ensure the accuracy of its regulation, with the development of network technology, to the new network automatic instrument and control technology is the inevitable trend of development.
