Chapter 21 Opening up the Core Base Area
Gao Wen thought that China is still very poor today, and the people are not high in terms of education level or per capita income. In addition, today's personal PC is mainly used in office, scientific research, and design, so for ordinary people, personal PC is a luxury and useless decoration.
In addition to using it to show off and play some simple games, it is not as good as a black and white TV set and a cheap FC game console, at least this pair can not only watch TV but also have a wealth of games to play, which can bring entertainment to the daily life of ordinary people more than personal PCs.
In this environment, the domestic market for personal PCs has naturally become quite limited.
Therefore, if Gawain wants to continue to promote the popularization of personal PCs, let personal PCs enter the lives of ordinary people and become the necessities of people's daily lives, so as to expand the consumer market of personal PCs, and then draw enough nutrients from the field of consumer electronics to feed the industrial field, it is impossible to talk about it.
The object is different, the environment is different, and the timing is different, so how can you do the same thing.
But it's not like he doesn't have any other way to go.
Since the domestic personal PC consumer market is still immature, why should he stumble in this regard, why not find a way to get a share of the industrial modernization that is in full swing in China.
In this era when computer technology has penetrated into all fields of industry, how can modernization be called real modernization if it is not prefixed with digitization and intelligence?
And this kind of digitalization and intelligence is exactly what he is best at.
Thinking like this, Gao Wen's mind suddenly opened. He thought that since the domestic semiconductor industry has a poor foundation, and it cannot compare with developed countries such as the United States in the hardware field represented by personal computer processors, why not make use of his strengths and avoid his weaknesses.
Starting from the relatively low requirements for computer hardware, as long as it is reliable and stable in the industrial field, establish a reliable core base area, first develop and expand this base area, and then use the base area as a backing to radiate its own strength to the surrounding areas. In turn, it draws nutrients from China's industrial modernization, and then counterattacks the consumer electronics market represented by personal PCs.
As for the field of home game consoles, this field has already begun to establish a base area, but Gawain has never planned to make it his core base area.
With self-knowledge, he knows that although the hardware configuration of the home game console represented by the Atari 2600 is not very high, and its central processing unit can even be said to be a product that has been eliminated from the first line, but this situation will not last long.
With the expectation of high-quality games and the fierce competition between home game console manufacturers, in order to allow players to have a better and more extreme gaming experience, home game consoles are bound to use the best hardware like personal PCs, rather than some built-in hardware such as first-line obsolete processors like the current Atari 2600.
In such a situation, Gawain is bound to be subject to the relatively backward semiconductor industry in China in the process of competing with other home game manufacturers, and is in a disadvantageous position in the competition.
So from the very beginning, Gawain gave his growing home game console business a clear positioning. That is, this plate can only exist as its own peripheral base, not only as the vanguard of its own outward expansion, but also as the first line of defense against foreign enemies.
Under such a positioning, if he wants to obtain a core base area that he completely controls himself, Gao Wen can only seek to sow his own spark and establish his own core base in the industrial field where the requirements for computer hardware are relatively low.
Thinking about it like this, he couldn't help but think of the most critical part of industrial intelligence - PLC.
PLC, also known as programmable logic controller, is an automation device invented by Richard E. Morley in 1968. The core design idea is to use software programming instead of hard-wired relay control to build a program control system. In the same year, General Motors developed design standards for PLCs. Since then, PLCs have been widely used in various industrial fields.
The 70s of the 20th century was the rise of PLC. Since Rockwell Automation first proposed 8-bit microprocessor-based PLCs in 1977, many manufacturers have followed suit and produced 8-bit microprocessor-based PLC products, such as the Intel 8080 and Zilog's Z80.
In the 80s of the 20th century, with the development of microelectronics technology and microprocessor technology and the application of PC, PLC technology gradually matured. The most typical example of this is the 8-bit microprocessor 8085-based PLC designed by Athani, which has a manual programmer and a CRT display terminal, on which the program segments can be displayed.
In the later nineties, with the official promulgation of the PLC international standard IEC61131, PLC technology entered the third period of development. At this time, the PLC began to develop from the traditional single machine to multiple processors in the system structure, and the development of the control system configuration from the independent control system to the distributed and remote control system. In addition to automated production lines, PLC-based distributed control systems (DCS), supervisory and data acquisition systems (SCADA), flexible manufacturing systems (FMS), safety interlock protection (ESD) systems, motion control systems, etc., have also been developed to improve the application scope and level of PLC in all aspects.
If you want to make a comparison, then the mature industrial control PLC can be said to be on par with the existence of CNC CNC.
CNC is like the Shaolin school, there are 72 stunts of this school, and each practice has to exhaust a lifetime of energy to practice. The PLC is more like the internal strength of Taoism, a variety of breathing and breathing methods, and the deep internal strength can bring the martial arts to the extreme.
It is not an exaggeration to say that as long as you have a good enough PLC, you can use PLC to build your own CNC system and DIY a machining center.
There are examples to follow, just like the s7-1500T series PLC developed by Siemens before his rebirth, as long as you have comprehensive experience in all-in-one machine development, you can use PLC plus private service motor with TIA software to integrate motion control and human-machine interface, DIY out of a machining center.
Of course, just like the martial arts wizard Tubo Master Gu Mozhi in "Dragon Babu", he used Taoist internal strength to urge Shaolin 72 stunts, and was seen by Xuzhu as flawed, and it was revealed that what he made was not pure Shaolin martial arts.
Although it is feasible to use PLC to DIY a machining center, it can also defeat a few Shaolin monks like Gu Mozhi, but once you meet a top master like Qiao Feng, you can only sit on wax. After all, there is no room for a little mistake between masters, and a little mistake is a difference of thousands of miles.
Compared with CNC professionals, which focus on machining, PLC is more suitable for general control tasks.
The control accuracy of ordinary PLC is not as high as that of CNC, and the total cost of high-end PLC with motion control is higher than that of CNC. Therefore, although the cost of ordinary PLC is lower, many users are still more optimistic about using CNC after comparing the overall PLC solution and CNC, because CNC has the two characteristics of high overall reliability and low total cost in comparison.
Compared with PLC, CNC is more integrated and modular in machining, which enables it to save a lot of costs in specific processes, staff training, equipment maintenance, etc., and makes its long-term investment return higher. And in machining, many of the operators are not automation programmers, and they also want to focus on the process, on mass production and customized machining, rather than on the general logic programming of PLCs.
Therefore, in the process of automation to digitalization, CNC and PLC have their own positions and characteristics. On the factory floor, when there are a large number of complex tasks and simple actions or processes at the same time, it is usually CNC and PLC that work together to complete the process requirements. It is also this cooperation between CNC and PLC that has laid the corresponding foundation for intelligent manufacturing.
