Eight, industrial control software is developing in the direction of advanced control
Since its inception in the early 1980s, industrial control software has been in development for 20 years. As an application software, industrial control software is constantly evolving with the rise of PCs. Industrial control software mainly includes human machine interface software (HMI), PC-based control software and production management software. At present, China has developed a group of real-time monitoring software platforms, advanced control software, process optimization control software and other complete sets of application software with independent intellectual property rights. Engineering and productization have made certain breakthroughs, breaking the monopoly pattern of similar foreign application software. . Through the application in hundreds of enterprises (devices) in the chemical, petrochemical, papermaking and other industries, it has promoted the technological transformation of enterprises, improved the control level of production processes and product quality, and created obvious economic benefits for enterprises. In 2000, the “Ninth Five-Year Plan†national science and technology research project “large-scale backbone petrochemical production system control and computer application technology†passed the acceptance test.
As an important part of industrial control software, the development of domestic human-machine interface configuration software has made great progress in recent years. The combination of software and hardware provides a relatively complete solution for enterprise measurement, control and management integration. On this basis, industrial control software will evolve from man-machine interface and basic strategy configuration to advanced control.
There is no strict and uniform definition of Advanced Process Control (APC). Control algorithms that are based on mathematical models and must be implemented by computers are collectively referred to as advanced process control strategies. Such as: adaptive control; predictive control; robust control; intelligent control (expert system, fuzzy control, neural network).
Because advanced control and optimization software can create huge economic benefits, these softwares are also worth more. There are already dozens of companies in the world, and hundreds of advanced control and optimization software products have been launched, forming a powerful process industry application software industry worldwide. Therefore, it is of great significance to develop China's advanced control and optimization software with independent intellectual property rights, to break the monopoly of foreign products and replace imports.
In the future, industrial control software will continue to move toward standardization, networking, intelligence and openness.

The type code of tapered roller bearings is 30000, and the tapered roller bearings are separable bearings. In general, especially in the size range involved in GB/T307.1-94 "Rolling Bearings - Tolerances for Radial Bearings", the outer ring and the inner assembly of tapered roller bearings are 100% interchangeable.
The angle of the outer ring and the diameter of the outer raceway have been standardized in the same way as the outer dimensions. Changes are not allowed at the time of design manufacturing. As a result, the outer ring and inner assembly of tapered roller bearings are universally interchangeable worldwide.
Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Compared with Angular Contact Ball Bearings, the load carrying capacity is large and the ultimate speed is low. Tapered roller bearings are capable of bearing axial loads in one direction and are able to limit the axial displacement of the shaft or housing in one direction
