Editor's note:

For more than 40 years of reform and opening up, China’s economic development conditions and development environment are undergoing earth-shaking changes. The economic structure is evolving to a stage of higher form, more complex division of labor, and more reasonable structure, and economic development has entered a new normal. The brand economy is a high-level economic form that integrates economic elements with the brand as the core and drives economic development. It is an important manifestation of the comprehensive strength and competitiveness of a country or region.

In the critical stage of building a well-off society in my country, actively promote brand building and play a leading role in branding, which is conducive to stimulating the innovation and creativity of enterprises, improving the quality and efficiency of the supply system, and realizing the upgrade of the global value chain.

In this land of Hunan, there are a number of outstanding national brands. The solicitation of "China's smart manufacturing to see Hunan—a case of China's outstanding brand Hunan construction" initiated by the Hunan Channel of People's Daily Online was officially launched. The reporter recorded a group of outstanding enterprises in Hunan through videos, pictures and texts, and adopted their products, technologies or services. , Inherit the spirit of craftsmanship, convey Chinese self-confidence, form a close emotional connection and value identification with the people, show the country's thriving happy life picture, and feel the majestic power of Hunan enterprises forging ahead in the vivid historical changes.

“Buying a boat and chartering a boat is not as good as building your own ships. You must first have your own core products before you can concentrate your resources to become bigger and stronger.” Talking about the hard work of more than ten years with his team, Chairman of Hunan Qitai Sensing Technology Co., Ltd. Wang Guoqiu opened the chatterbox.

After driving more than 40 kilometers from Changsha to the east along Hangzhou-Changzhou Expressway, we arrived at Hunan Qitai Sensing Technology Co., Ltd. located in Liuyang Economic Development Zone (High-tech Zone). In this cluster of industrial enterprises, the sign of "Qitai Sensor Internet of Things Industrial Park" is calm and low-key. The few clear gray buildings with ordinary appearances are the office buildings and factories of the industrial park. There are few employees in the park, which makes them feel particularly refreshed.

The scale of Changsha's construction machinery industry is the largest in the country, but key components such as hydraulic sensors have long been dependent on imports. This dilemma is being solved under the long-term unremitting scientific research of local enterprises. The hydraulic sensor assembly line independently developed by Hunan Qitai Sensing Technology Co., Ltd. has been mass-produced in June this year, completely meeting the needs of Changsha and even the national construction machinery industry for supporting hydraulic sensors.

The price of a piece of construction machinery and equipment ranges from hundreds of thousands to millions of dollars. But no matter how large the body is, the precise conduction of the small hydraulic sensor is inseparable. The sensor's sensitive chip is only the size of a button, but it shoulders the important task of signal perception, and its core technology has long been mastered by developed countries in Europe and the United States.

"Core" manufacturing

Fill in the blank of my country's factory production line

"Sensors are very basic industrial technology. To what extent is it based? Just like Arabic numerals are to mathematics." Wang Guoqiu, chairman of Hunan Qitai Sensing Technology Co., Ltd., said, "For example, if the brake system of high-speed rail is missing the test The whole high-speed rail has to lie down because of the pressure sensor. No one dares to sit or run without a car."

The pressure sensitive chip on the pressure sensor is the key to the sensor. A "button-type" pressure-sensitive chip with a diameter of no more than five or six millimeters can accurately convert pressure data into electrical signals and transmit them to the receiving and processing terminal. It can be widely used in construction machinery, rail transit, automobiles, firefighting, and smart cities. , Petrochemical, aerospace and other fields.

But for a long time, this type of core chip technology and market has been basically occupied by companies in Japan, Britain, Germany, Switzerland and other countries, and the domestic self-sufficiency rate is less than 1%.

"Industrial development has this demand, but it is not well done in China." Wang Guoqiu said that there are more than 26,000 types of sensors, while China can only do more than 6,000. Among them, the ones that can do well are very few. number. Facing the domestic and military needs and the blockade of foreign technology, in 2006, Wang Guoqiu decided to start researching and developing the Chinese's own sensitive chips.

"Think about it now and I'm afraid. A few people started doing it ignorantly, but if any link in the development process gets stuck, the previous effort will be in vain." A lot of "tuition fees"-many equipment is not suitable after being developed, and must be re-improved; technical and technological ideas are wrong, and must be re-adjusted.

Until 2019, a standardized high-standard pressure-sensitive sensor chip production line of Qitai was completed. From core technology, key processes and equipment, to plant design, chip testing, and packaging, Qitai team independently completed. Since then, Qitai has overcome the problems of the whole production process of "domestic cores" and filled the gaps in my country's factory production lines.

"Core" journey

Let more and more companies realize the difficulties of domestic chips

As an important part of Changsha East Wing, Liuyang Economic Development Zone (High-tech Zone) has formed leading industries with electronic information, biomedicine, and smart equipment manufacturing, with health industry and remanufacturing as featured industries, and taking the lead in the construction of Changsha’s display function Devices, biomedicine, environmental governance technology and applications, and carbon-based materials are the four industrial chains of "three mains, two specials and four chains". The electronic information industry, led by Lens Technology, Huike Optoelectronics, and Qitai Sensing, has developed into a "special, refined and specialized" characteristic industrial park for electronic information in Hunan Province.

Qitai Sensing, as a leading company in the sensor industry, is also a steel and iron backbone that supports the high-quality development of the industry. The first phase of Qitai's pressure-sensitive chip factory with a cleanliness of more than 6,000 square meters and a cleanliness of 100 will produce 6 million chips and 2 million sensors each year, with an annual output value of 1 billion yuan; to be phase 2 After the project is completed, the annual output value can reach 5 billion yuan.

When it comes to the future, Wang Guoqiu is even more confident. Due to the relatively weak foundation of my country's sensor industry, with the accelerated development of my country's economy today, with the "dual cycle" development strategy taking root in the hearts of the people, the major development of the local sensor industry is inevitable. With its advanced advantages, Qitai Sensing will accelerate its development in the field of sensor sensitive chips. The development of one type of chip and the development of one market will form an industrial forest from point to surface in the field of sensor sensitive chips. With sensors as a strategic fulcrum, it provides a wealth of software and hardware products for the upcoming unmanned platform. "The so-called "unmanned" means that the work is handed over to the sensor, and the sensor has no other ability to collect signals." Wang Guoqiu introduced. Obtaining signals is only the first step. Around unmanned applications, there are still various technical standards, software and hardware products, and support platforms that need to be developed. In the future, Qitai hopes to become a "business card company" in the field of artificial intelligence in China.

When it comes to the promotion and application of chips, Wang Guoqiu is also a bit embarrassed. On the one hand, China needs its own core technology, but when its own core technology comes out, it is not easy to enter the market. Application manufacturers tolerate high prices for imported products, but do not accept the same prices for domestic products. In fact, in the field of basic manufacturing, the cost of foreign countries is not much higher than that of domestic products. The demand for water and electricity is equivalent, and the cost of materials is also equivalent. This field is not a labor-intensive industry. Foreign countries take the lead and occupy a huge industrial advantage. There is no advantage for a period of time. Therefore, application manufacturers must have an objective understanding of these characteristics and understand the difficulties of chip companies. (Reporter Lin Luo and intern Liu Yunxia)
