Cultivate innovative fertile soil, form a group of singles champion and supporting expert "Little Giant" to help "Su" accelerate the running

A few days ago, the 2022 National Specialty New SME Development Conference opened in Ning. The reporter learned that as a large manufacturing province, Jiangsu has made every effort to build a new special SME agglomeration in recent years. Among them, Nanjing, the provincial capital of Nanjing, is the first to focus on the "2+2+2+X" innovative industrial system to guide the small and small The road to the new development of specialized specialty has been cultivated 106 new "little giants" enterprises and 285 provincial -level new "little giants" enterprises, forming a number of "singles champions" and "supporting experts" that mastered unique skills.

"Rail" becomes "track"

Create a strong "heart"

The construction of a multi -level rail transit system in Ji Li and accelerating the development of rail transit is an urgent need for Jiangsu's economic and social development; and on the province's urban rail transit construction track, Nanjing Yima runs out of the "acceleration" first, which is inseparable from the core equipment behind it. support.

In the production workshop of Nanjing Winshi Electronics Technology Co., Ltd., many production equipment "full horsepower", workers shuttled busy, and a hotness facing the sky. They are assembling the "heart" of rail transit vehicles -traction transmission equipment.

"We have a history of nearly 30 years based on the development and production of electrical equipment in rail transit vehicles." Chen Ailin, deputy general manager of Nanjing Winshi Electronic Technology Co., Ltd. told reporters that they are mainly produced by railway trunk, urban rails and special rail vehicles. Temporary transmission equipment, auxiliary power supply and control cabinet and other key electrical products.

Among them, it is known as one of the three core technologies of urban rail transit. Its independently developed linear motor vehicle traction system is currently the only domestic direct -line motor vehicle traction system with a vehicle qualification qualification. It has achieved the "zero" breakthrough in my country's rail transit independent industrial chain and can replace similar equipment for imports. "We are currently ranked third in the industry in the domestic market." Chen Ailin said proudly.

Nanjing Winshi Electronics can obtain industry leadership, thanks to continuously achieve technological breakthroughs during the early research and development stage; "rigorous" is the core principle of their design and development. Direct transmission equipment must be tested after being formally put into use. For example, there is no failure time to detect the average failure time, that is, the two failure interval time, it takes 15,000 hours to reach the standard.

The reporter learned that helping the construction of Nanjing's transportation, the projects that Nanjing Winshi Electronics has been delivered to the use of Metro Line 1 and Line 2 extension line and additional purchase projects. The traction system project of Metro Line 5 is also being delivered.

"At present, we have developed in -depth research and development of special models for different application scenarios for special models such as single -track vehicles, rubber wheels, and linear motors." Chen Ailin said that Nanjing Winshi Electronics will continue to surround the surround In the field of urban rail traction transmission technology, according to the major key and common technical problems of the development of the urban rail transit industry, we will further carry out application technology research and engineering development.

Aiming at "Card Neck"

Make "big tricks" in the "small world"

Speed ​​up digital development, Jiangsu has comprehensively increased the 5G coverage rate in recent years and promoted the construction of smart cities. "5G transmission can not drop the frame, the signal is stable and fast." If you want to let the electronic products run stably, it is inseparable from the supporting quartz crystal components. Nanjing China Electric Panda Crystal Technology Co., Ltd. In this millimeter -level "small world", constant innovation breakthroughs.

Established in 1993, Pandan Corporation initially produced resonant products, until 2000 in the field of SMD oscillator products. "Compared with the resonant, the oscillator has a higher degree of integration and high product added value. It is mainly used in communication and security." Gao Zhixiang, deputy general manager of Nanjing China Electric Panda Crystal Technology Co., Ltd. The size of the oscillator product produced by the enterprise is getting smaller and smaller, "from coins to nails to sesame grains", the minimum has reached the standard of 1.2 × 1.0 mm.

In order to solve the problem of the "card neck", domestic 5G communication equipment is independently developed with wide temperature and high precision temperature supplement oscillator. Gao Zhixiang told reporters that at present, the Hongji Station antenna module and small base station equipment of the four major communication equipment manufacturers in the world need to use this series of temperature supplementary oscillating device. Previously, it mainly relied on a few foreign crystal manufacturers imported products.

"The component industry is the foundation of the manufacturing industry. The dependence on import formation will seriously restrict the development of my country's manufacturing industry. With the development of the national 5G new infrastructure, the market demand space of 5G communication equipment with wide temperature and high precision temperature supplement oscillator is huge. "Gao Zhixiang told reporters that Panda Crystal Company aimed at the project a few years ago and cooperated with relevant scientific research institutes to overcome the problems one by one by repeated tests, and finally successfully filled the domestic gap.

As Jiangsu actively builds a new engine of the digital economy, it continues to deeply cultivate 5G, artificial intelligence and other fields, and puts forward higher requirements for the innovative capabilities of SMEs. "In the future, we will continue to increase the development of new products, accelerate the construction of the photoresal process platform, break through the difficulties of the development and development of small size and high -base chips, continuously improve the innovation capabilities, and promote the development of quartz crystal components technology."
