AI intelligent robot realizes unmanned intelligent car wash

A few days ago, the Shell Finance section of the Beijing News reported that the "AI Intelligent Inspection Robot" project undertaken by China Mobile Beijing Company (Beijing Mobile) was put into use in the power distribution room of China Mobile International Information Port No. The digital and intelligent unattended computer room landed in Beijing. According to NetEase News, in early June, Xinjiang Kezhou People's Hospital and Jiangsu Provincial People's Hospital were successfully connected, and the first 5G ultra-remote robot-assisted lower abdominal vena cava surgery was completed using the nationally produced "Tumai" robot. AI intelligent robots are increasingly appearing in the necessary scenes of our lives, and unmannedization has gradually become a social development trend.

The split trend of the auto parts industry

At the media communication meeting during the Shanghai Auto Show, Dr. Almar Degenhardt of Continental Group said that according to the group's expectation, the internal combustion engine will completely withdraw from the historical stage around 2040. In the technology roadmap announced by the group, the automobile manufacturing industry will develop the post-Z internal combustion engine technology in 2025; around 2030, the production of the post-Z internal combustion engine will start; by 2040, the internal combustion engine will be driven by cleaner power technology. replace. I personally think that this thing is not completely smooth, mainly because the roadmap is a long-term trend, and the entire powertrain structure change is gradual.

Semiconductors originated in the United States, why did they fail to monopolize the market?

The semiconductor industry is mainly used in various high-tech products, including computers, hard disks, optical drives, mobile phones and other products. The semiconductor industry can make products smaller and smaller, with lower power consumption and lower service life. But it's getting longer. The emergence of smart phones represents a high degree of integration of material technology, semiconductor technology and electronic technology. Let's talk about Huawei's latest mate20 pro mobile phone. It has the most advanced technology in semiconductor technology. It only has a 7-nanometer processing chip, which drives a 40-megapixel, triple-camera, and 4200mAh battery.

IGBT has long relied on foreign giants in the new energy industry, and it is difficult to find a "core"

Since 2018, new energy vehicles have maintained a relatively rapid development. On December 10, the National Passenger Vehicle Market Information Joint Association (hereinafter referred to as the "Passenger Association") released the production and sales data of my country's passenger vehicles in November. The wholesale sales of new energy vehicles in November reached 136,000 units, a month-on-month increase of 19.1% and a year-on-year increase of 69%; of which

The process of domestic substitution of semiconductors has accelerated, and the semiconductor and component sectors have recovered rapidly

Guosheng Securities Research Report pointed out that the supply of semiconductor materials is limited, and the process of domestic substitution is accelerated. In 2021, the global semiconductor material market will reach a new high of US$64.3 billion, and the demand in mainland China will account for 18.6%. Trade frictions and natural disasters have led to limited supply of semiconductor raw materials, resulting in the possibility of supply cuts for products with high market share from foreign manufacturers such as photoresist, CMP materials, and electronic specialty gases, which further promotes the demand for domestic materials and the progress of domestic substitution. With the advancement of technology and technology and the gradual improvement of China's electronic industry chain, various manufacturers that have entered mass production and supply have begun to emerge in the field of materials. The delivery time of advanced parts and components of semiconductor equipment has been extended by more than two times, and the replacement has been accelerated. According to South Korea's etnews report, the contradiction between the surge in demand for semiconductor equipment and the insufficient expansion of upstream components has formed a bottleneck. The lead time for advanced components of semiconductor equipment has been extended from the usual 2-3 months to more than 6 months. The delivery time of advanced components produced in the United States, Japan and Germany is particularly serious, mainly because component manufacturers usually have heavy assets, and the expansion speed is slower than that of semiconductor equipment manufacturers. The supply of semiconductor equipment parts is in short supply, and the market space exceeds 20 billion US dollars. The market share of the top ten key subsystem suppliers in the world has remained at about 50% since 2010. The process of domestic substitution has accelerated and continued to make breakthroughs.
