Among the many teams participating in the construction of the Hangzhou National Edition Pavilion, Zhejiang Dafeng Industrial Co., Ltd. is an important member.

Under the leadership of the company's chief engineer Yan Huafeng, the Dafeng team "rescued the field" to take over the celadon screen fan intelligent mechanical system project in the museum, and achieved a motionless "Thousands of Rivers and Mountains".

How does a private enterprise "rescue the field" national boutique handed down project? Where is the research and development of a celadon screen fan intelligent mechanical system?

Through Yan Huafeng's answer, we learned about the level, pattern and action of Zhejiang's private enterprises, and felt a strong force in Zhejiang's new vision in Zhejiang's new vision of "building a global advanced manufacturing base".

Who else can pick up this tricky job

The stage lighting audio video system and custom seats of the lecture hall, lift platforms in the basement, southern study, etc. are available in many places in the Hangzhou National Edition Museum.

After briefly introducing these projects, when talking about the intelligent mechanical system of the celadon screen fan, Yan Huafeng's voice has significantly improved: "This is the most difficult to cooperate, and it is rare in previous projects."

In September 2020, the Hangzhou National Edition Museum has entered the construction stage. However, the promotion of the solution that the celadon screen fan moved into a deadlock.

Although the requirements of the plan are only two points: stable and accurate, it is easy to be difficult to say.

Celadon is too crispy, too heavy, too high, and too large. Each celadon screen fan is several meters high and weighs about 4 tons. Machinery must not only set up these "guys" safely, but also ensure that they will not shatter due to inertia during the track and translation. "The equipment manufacturing industry usually has a lot of dealing with steel, and I haven't seen any project to deal with celadon!" Yan Huafeng sighed.

In addition, the spatial density of porcelain discharge determines that the mechanical error must be small. According to the requirements, when the screen fan rotates to the same plane, the distance between each other should be strictly controlled within one centimeter. When the distance is too wide, the screen is "leakage", and the "Thousands of Miles and Mountains" also lose beauty.

Earlier, the Hangzhou National Edition Hall has rejected the plan of 4 teams. Some can only ensure that it is installed, and it cannot be moved. Some designed the device too heavy, and had to dig a deep pit under the door frame. There was neither beauty, but also stretched the construction period -at the time, the construction period of the Hangzhou National Edition Museum had been tight enough to build and design. A reply from a Nordic company is: I haven't done it before, which can be achieved in principle. But the quotation is greatly exceeded the budget.

Who else can pick up this tricky work?

The relevant person in charge of Zhejiang Construction Engineering of the building found Dafeng. Earlier in the Zhejiang Academy of Music, the Dafeng team that had been unconventional to lifted the stage was created, leaving him the impression of "being able to make strange equipment". Two weeks later, the Dafeng team participated in the report.

"We prepared the content of the report for at least half an hour. Just 20 minutes, Mr. Lu Wenyu, the design team of the architectural creative creative creative design team, immediately stood up and said excitedly. Pride in the tone.

Since then, the 1: 1 test model has been produced. Wang Yan, the main creator of the Hangzhou National Edition Museum, went to Dafeng to "accept" in Yuyao's production base. Seeing it is true, everyone is finally at ease.

"The high -tech trend of manufacturing is already very obvious"

In the eyes of the mechanic, celadon is a beauty, and it is also an incredible object. The screen fan is a door and a window -it needs to move and rotate large horizontally to different positions, allowing pedestrians and teams to pass, or let the sun go into the hall.

The layman watched the fun, and the interior looked at the door. Seeing the lively person only noticed the stunning of celadon, or only when "moving" is just a problem that can be solved by a key on the control panel. People who know the door know how much wisdom is condensed.

During the interview, the reporter has been asking the difficulty of making the intelligent mechanical system of a celadon screen fan. In this regard, Yan Huafeng was a little embarrassed.

He frowned and thought about it for a while, so he had to answer: "If it is difficult, no one in the world has done it. It is really difficult to say that it is really difficult to talk about. We just combine a few big and mature technology."

Indeed, some of the many Dafeng projects he participated in the intelligent mechanical system of the celadon screen fan is more difficult. For example, the dynamic sculpture of the "一 比 比" in Wuxi City, combined with the eight different shapes of the space S -curve columns, combined with the average distributed 45 flowers, rotated the rotation in the three -dimensional space, forming a 18 -meter -high human modeling shape ; At the "Hangzhou 8 minutes" at the Asian Games in Jakarta, 360 -degree rotating 4 -section robotic arm support with a total weight of more than 100 tons of smart dance screen, an extension height of more than 13 meters, and 54 axis running curves ...

This self -developed celadon screen fan intelligent mechanical system integrates technologies such as motion control, logical control, safety monitoring, real -time synchronization and other technologies. A variety of algorithms such as the embedded anti -shaking algorithm and the stacked parabolic line type can ensure the smoothness of the celadon screen fan. "Walk" 16 sports trajectories. The equipment's security control system has reached the highest standard SIL3 level of EU certification. "We have reached the international first -class level in the field of cultural equipment." Yan Huafeng said.

Wang Yan also praised Dafeng: "I did not expect Zhejiang private enterprises to reach this level!"

As the person in charge of the research and development of a celadon screen fan intelligent machinery system, Yan Huafeng saw that technology and culture are moving towards deep integration. Dafeng is a national key high -tech enterprise. It has a national post -doctoral research workstation. Each year, more than 5%of sales are also available for research and development cost investment technology development. He told reporters: "The outside world generally believes that stage machinery is manufacturing. In fact, the trend of digital technology and cultural innovation empowering traditional manufacturing is already very obvious!" Yan Huafeng's work photos

"Do our work,‘ art tall man ’s boldness’ ””

Those who are successful often accumulate.

The invention of "multi -door fan rotating door laser collision anti -collision method, system, electronic equipment and storage medium" is one of the patents applied to the country after the completion of the celadon screen fan intelligent mechanical system. It determines whether to control the door fan to stop running by obtaining data from the door fan obtained by the laser sensor and the target of the target.

"By installing multiple laser sensors at the bottom of the front and back of the door fan, we achieve no blind spots in the detection area, effectively filtering the interference of the laser sensor, and avoiding a misunderstanding." The way.

In fact, every time Dafeng completes a challenging device, Dafeng will apply for a new patent. There are more than ten numbers. From this point of view, only three new patent celadon screen fan intelligent mechanical systems are naturally not "difficult".

With the joint efforts of more than 500 R & D personnel in the enterprise, Dafeng has obtained more than 1,000 patents, nearly 200 invention patents, and led 15 national and industry standards.

However, today's industry leaders have also encountered the contempt of "individual households to engage in contracting." The threshold of the style and equipment manufacturing industry is not high, and there are more than 100,000 large and small enterprises in the country.

Generally, considering stability and ability, state -owned enterprises are often the first choice for national large projects. Today, the boutique handed down project is full of prosperity, and the forward -looking vision and pattern of Zhejiang private enterprises are proven.

In the 1990s, the cultural consumption of the masses rose. Dafeng turned his attention from the power supply from the stage, the venue seat, and the acting equipment on the stage. At that time, there was a "blue ocean". There were only a handful of domestic manufacturers with production capacity, and the price of foreign products was unattainable.

Yan Huafeng was sent to Las Vegas in the United States for half a month, especially by the sound, light, electricity, and dance beauty of the classic show "Card Show" of the Sun Circus. Intersection

"At that time, we judged that it was necessary to stabilize the market, and we must make machinery and control the simultaneous development. While continuously breaking through innovation in the mechanical field, outstanding talents in the control field are also accepted. We then continue to cultivate and experience. It has reached the world -class level. "According to him, the cost of" two hands "is high. Generally, companies will choose to outsourcing. The teams who have missed the Hangzhou National Edition Museum Project are lost.

"Do our work, 'art talls boldness'! A lot of big projects, the grades are bright, the grades can be dazzling, so that people can go to a high place'." Yan Huafeng believes that Hangzhou, which reflects the national level of intelligence manufacturing, The participation experience of the National Edition Pavilion will inevitably become an important stroke in Dafeng's resume.
