Product Introduction

DO820 is a high-performance industrial automation communication module that uses high-speed CMOS devices, supports MODBUS protocol, and supports
hardware flow control. It is an ideal choice in the field of industrial automation.

Our country’s educational achievements are obvious to all. Almost 100% of the nine-year compulsory education and the
number of universities are constantly expanding. Last year, our country’s university graduates
reached 8.47 million. The huge educated population meets the talent needs of all aspects of
capital-intensive industries; infrastructure On the other hand, we have established the world”s largest
road and railway network, known
as the “infrastructure maniac”, which ensures the smooth transportation of raw materials and
finished products.
As can be seen from the above, there is no shortage of talents in China”s manufacturing industry
in the first two stages,
but now we have come to the third stage of intelligence-intensive industries. What is needed at this
stage is education, including higher education and high-end vocational education, to cultivate talents.
R&D personnel, engineers, professional operators and so on, and this is
what we are lacking today.

In terms of cultivating R&D personnel and engineers in higher education, my country”s current stage
can only be said to
be unsatisfactory. There are 985 and 211 universities that provide some talents, which can barely
meet the needs of the industry. Although the overall quantity and quality are still not enough, and as the
progress deepens, This shortcoming will become more obvious.

Relevant reports show that a bachelor”s degree is the basic academic requirement for talents in artificial
intelligence-related positions. Especially in the field of artificial intelligence chips, up to 88.4% of positions
require a bachelor”s degree.
Most positions in technical fields such as intelligent robotics, machine learning, natural language processing
, intelligent language, and computer vision require a master”s degree or above.
