Let's just say.
The core technology of PLC is in the hands of foreigners, and PLC is used in large industrial occasions, so stability becomes particularly important. Domestic PLC has been unable to catch up with foreign countries, so the development will be discounted.
The focus of embedded system is function satisfaction, which is similar at home and abroad.
The hardware chip is basically universal.
The difference is that the effect of the software is different.
The key is that embedded systems are widely used.
Therefore, the embedded system is not entirely technology.
But more applications.
So the choice is wider.
I don't know if you understand this.
What I want to say is,
Enclosed please find.
Development prospect of embedded system
In recent years, the products of embedded system are becoming more and more perfect, and have been widely used in all walks of life around the world. The development and application of embedded system products has become a new national economic growth point for China's informatization to drive industrialization and industrialization to promote informatization development.
With the intelligentization of consumer appliances, embedded is more important. We usually see mobile phones, PDAs, electronic dictionaries, videophones, VCD/DVD/MP3 players, digital cameras (DC), digital video cameras (DV), USB flash drives, set-top boxes, high-definition televisions (HDTV), game machines, smart toys, switches, routers, numerical control equipment or instruments, automotive electronics, home appliance control systems, and medical instruments. It can be predicted that with the rapid development of Internet and the appearance of cheap microprocessors, embedded systems will form a larger application field in daily life.
In China, during the development of embedded software, the government fully realized its important role and gave strong support in terms of policies and funds. In 2004, the National Development and Reform Commission, the Ministry of Science and Technology and the Ministry of Commerce jointly promulgated the Guide to Key Areas of High-tech Industrialization with Current Priority, and regarded the embedded software industry as an important area of national development.
In recent years, the development speed of embedded software in China has been higher than that of China software industry and global embedded software industry, and its proportion in China software industry and global embedded software industry is increasing. At present, the proportion of China's embedded software industry in the whole software industry has exceeded one third.
From 2006 to 20 10, the scale of embedded software industry in China will continue to grow rapidly, with a compound annual growth rate of 25.8%, reaching 333.96 billion yuan by 20 10.
The development of embedded software industry in China is facing good development environment and opportunities, including the government's attention and support, the integration opportunity of information industry and traditional industries, the unformed monopoly situation, the good foundation of China manufacturing, the rise of free software movement and so on.
At the same time, it is undeniable that for a long time, due to many problems such as talents, publicity, funds and the unique combination of software and hardware of embedded systems, the demand for embedded software talents has been in short supply.
Present situation of embedded teaching in colleges and universities
The lack of embedded talents in China is mainly due to various problems existing in domestic higher education.
At present, software education in colleges and universities in China is mainly based on application software, and students are more exposed to application-level technologies such as. Net and java. There are not many schools offering embedded software specialty, and schools can't provide enough practice opportunities for students. Teaching in some schools is a mere formality, with only theoretical explanations and no practical operation, which is extremely unfavorable for college graduates to enter the embedded development field.
Although some schools have started to offer embedded teaching, there are no teachers who can undertake teaching tasks. In some universities, teachers of related majors generally have a strong theoretical foundation, but little practical ability and project experience, so the students' ability and project experience cultivated in this way naturally cannot meet the requirements of embedded R&D enterprises for talents.
