My 1982

Through some of the fake and learning of Li Zhongxin, he is the thing of the automation! It is also a lot of understanding.

Industrial automation this discipline! According to Li Zhongxin's analysis, the machinery device or production process achieves measurement, manipulating information processing and process control in accordance with expected targets without artificial direct intervention.

Automation technology is to explore and study methods and techniques for realizing automation processes. It is a comprehensive technology involving mechanical, microelectronics, computers.

At the same time, automation technology has also promoted the progress of the industry. Today, automation technology has been widely used in the fields of mechanical manufacturing, electricity, construction, transportation, information technology, etc., and become the main means of improving labor productivity.

According to Li Zhongxin's simple history information about China's automation development, China is here! During the 1940s to the beginning of the 1960s, because of the market competition, resource utilization, reducing labor intensity, improving product quality, and adapting to mass production needs, China has begun the way of automation development.

Among this time period, mainly for a single automation phase, various single automatic processing equipment, and continuous expansion of the application and development in the depth direction.

According to books and Li Zhongxin, the most typical results and products are basically necessary to be a hardware CNC system.

At this time, China's earliest number of control machines was the first CNC machine tool, which was produced in 1958.

This machine is jointly developed by Tsinghua University and Beijing's first machine tool factory. It is the crystallization of Beijing's first machine tool factory and Tsinghua University.

At that time, there were only a few industrial developed countries trial successful CNC machine tools.

Trial such a machine, the United States used four years, the UK used two and a half years, Japan is going forward.

At that time, CNC This cutting-edge technology is basically in the hands of those European and American countries, so that this technology is basically blocked in China.

The CNC system of this machine, at the time, was developed in China and did not have a sample and more complete technical information available.

All staff participating in the development include professors, engineering technicians, workers, students, etc., the average age is only 24 years old. In this group, in the middle of the group, I have shown that I have invited Li Zhongxin to Tsinghua University to give a professor to the students. Professor.

They only rely on the information card and a schematic for reference only, and they attacked another difficult time. I used the 9-month time to finally develop successful CNC systems, which control the workbench and horizontal slippers of the machine. The finishing head feed movement is achieved, and three coordinate linkages are achieved.

The successful development of this CNC machine tool has laid the foundation for the high degree of automation of China's machinery industry.

After Li Zhongxin saw the information in this place, he suddenly felt that there was a very pit, and several professors on the Tsinghua University were such a bad person. At that time, he actually in front of these professors. Talk, give them some things about the development of automation, Li Zhongxin is depressed, this is definitely a big knife in front of Guan Gong, he didn't have a few pounds of yourself!

I don't know, the more I know that Li Zhongxin felt a pressure. He felt that this public class will be very pit, at least pitted in him a long time.

This thing is the thing that Li Zhongxin promised. He must be completed. Otherwise, if you pay attention to integrity, Li Zhongxin does not want to throw him with the kind of integrity he built.

After Li Zhongxin lost the kind of trouble, he continued to study the history of development. Li Zhongxin saw that at that time in the mid-1960s, the market competition intensified, requiring product update, high product quality And adapt to large-scale mass production needs and reduce labor intensity.

At this time! Mainly based on automated production lines, on the basis of single-alone automation, various combination machine, combined production lines, and software digital control systems have been used for machine tools, CAD, CAM and other software to start design and manufacturing in actual projects, this stage Hardware processing equipment is suitable for production and processing of large medium batch. Typical results and products: Automatic production lines for drilling, boring, and milling.

In the middle of the 1970s, the market environment changes, making many varieties, the general problems in small and medium-sized mass production, require automation technology to develop to its breadth and deep development, so that the relevant technologies are highly synthesized, and the overall performance .

Since the early 1970s, American scholars have made great changes in the field of automation. CIM has gradually been accepted by people; CIM is also an integrated corresponding technology, which makes a scattered unit automation technology set into an optimization. overall.

The so-called philosophy is that enterprises should analyze and overcome existing "bottlenecks" based on demands, thereby achieving thoughts on improving strength and competitiveness.

As a corresponding technology, general data acquisition, distribution, sharing, network and communication; shop layer equipment controller; computer hard, software specification, standard, etc.

At the same time, parallel projects act as a new working model began applying and active in the field of automation in the late 1980s, and will further promote the integration of unit automation technology.

From the development trend of industrial automation, intelligence is its core part, so-called intelligent manifestation is there in it.

For example, when the flow meter needs to perform temperature, the pressure is required to measure the flow, temperature and pressure, and the comparator is required to calculate, and now a smart traffic transmitter can be packaged. A task.

It is better to say that a intelligent actuator, due to a variety of self-diagnostic functions, the maintenance forecast is possible.

If the actuator adjustment valve is more than a certain length of the stem stroke, the signal notification repair person will be sent to the sealing filler; and the staff can also notify the staff to intervene when the action is too frequent, so as not to occur; When used for corrosive media, as more than a certain flow rate and working time, a signal can be sent to replace it in time because there is no corrosion that is not corroded.

In terms of industrial control, the algorithm of past control can only be completed by the regulator or DCS. Today, an intelligent transmitter or actuator, as long as the PID module can be implanted, you can be with the relevant live meter. Autonomous regulation is achieved at the scene; thus achieving the thorough dispersion of control, thereby reducing the burden on the DCS host, making adjustment more timely, and improving the reliability of the entire system.
