"New Craftsman" in the Intelligent Age (Visit to New Types of Work①)

  Artificial intelligence trainers, online learning service providers, digital managers, health care providers... Since last year, the Ministry of Human Resources and Social Security has announced three batches of 38 new occupations.

A wave of new occupations grew rapidly from scratch, becoming a footnote to the vigorous development of new technologies, new formats, and new models, demonstrating the tremendous vitality of China's economic and social development.

  Starting today, we have launched a series of reports on “Visit to New Types of Work”, focusing on industrial manufacturing, life services, health, agriculture and rural areas, and introducing the development stories of new occupations and types of work in China.

  The "Proposals of the Central Committee of the Communist Party of China on Formulating the Fourteenth Five-Year Plan for National Economic and Social Development and Long-Term Goals for 2035" put forward "unswervingly build a manufacturing power" and "promote the Internet, big data, and artificial intelligence to equal the depth of various industries." Integration to promote the development of advanced manufacturing clusters."

  Technicians are an important foundation supporting China's manufacturing.

Recently, our reporter interviewed 4 technicians in the field of industrial manufacturing.

They are the "new craftsmen" in the intelligent age, engaged in new types of work and possessing many new skills.

  Virtual reality engineering technician Zhang Jianwei——

  The "game" he played was unusual

  Holding the steering wheel, manipulating the car on the screen, avoiding, accelerating, turning... Friends said that Zhang Jianwei's job is to "play games."

  Zhang Jianwei, 32, is a "cloud trainer" at Alibaba Dharma Academy and a virtual reality engineer.

In fact, his job is much more complicated than playing games.

  Zhang Jianwei's autonomous driving laboratory has developed an intelligent logistics robot "little donkey" that can carry out unmanned delivery in communities, schools, parks and other places.

During this year's "Double 11" period, 22 logistics robots led by "Little Man Donkey" shuttled through the Zijingang campus of Zhejiang University. They were divided into 16 groups and delivered packages to 27 buildings within 10 minutes.

  The task of "Little Man Donkey" may seem simple, but it is full of challenges.

"There are people coming and going on campus, even if it is a real person driving, it is quite difficult." Zhang Jianwei told reporters that his job is to make logistics vehicles move better and avoid obstacles through continuous testing and updating of algorithms.

In a mixed traffic environment, the "Little Man Donkey" has been able to deal with complex road conditions in a timely manner and select the optimal route in seconds.

  How to train autonomous driving to be the most effective?

Of course, let the self-driving car run in reality, it is best to accept experience in extreme environments such as wind and snow.

However, extreme scenes in the real world are unacceptable. It may take 1 month to reproduce an extreme scene, while on a simulation platform, it only takes 30 seconds.

Zhang Jianwei's job is to build a virtual scene first, and then "play the game"-test autonomous vehicles on the simulation platform.

  But the simulation scene is not a real scene after all, and there is still a gap between the scene that relies purely on algorithm simulation and the reality.

In April of this year, Alibaba Dharma Academy launched a new platform—autonomous driving hybrid simulation test platform. The platform uses simulation technology combining virtual and reality. On the one hand, it introduces road test data and on the other hand, it uses "cloud trainers" Create real human intervention actions, relying on the "hybrid" of algorithms and human intervention to simulate various extreme scenarios more efficiently.

  Where do drive test data come from?

"The little man donkey provides us with a lot of data." Zhang Jianwei said that when delivering the goods, the "little man donkey" will record the passing scenes, and then the engineer can build these scenes on the simulation platform, and then let others Self-driving cars are trained in these simulation scenarios.

  Zhang Jianwei's life also goes back and forth between "virtual" and "reality".

When driving on weekdays, when he encounters a sudden brake, he always thinks: "I want to simulate this scene!"

  Industrial Internet Engineering and Technician Wang Qi——

  Specializing in the "worries" of traditional enterprises

  Since August this year, Wang Qi, senior architect of Tencent Cloud Intelligent Manufacturing, has been based in Zhangjiagang, Jiangsu.

He determined that this city has a great demand for the industrial Internet.

  Zhangjiagang is an industry-based city with more than 17,000 industrial enterprises, which is a typical county economic development.

However, traditional industries account for a relatively large proportion, and the local government has a strong willingness to help enterprises transform.

In June this year, Tencent Cloud (Zhangjiagang) Industrial Cloud Platform, jointly built by Zhangjiagang City Government and Tencent Cloud, was officially launched.

Soon after, Wang Qi came to Zhangjiagang, ready to show off.

  However, after visiting several companies, he found that there is a distance between reality and vision.

"Talking to some private enterprise bosses about the Industrial Internet, they are not very interested, or even resistant." Wang Qi told reporters.

Most of these bosses started from scratch, and they felt that their production and management methods did not need to be changed.

  "In fact, many times, traditional enterprises need Internet platforms, but they don't know it." Wang Qi said that his task is to explore these needs of enterprises.

  Once, Wang Qi chatted with the boss of a centrifuge manufacturer. The boss recently had an annoyance: He is getting older and is considering handing over the company to the next generation, but the younger generation is not familiar with the company’s business and the company’s customers The resources are in the hands of the salesperson. Once the salesperson leaves, the company may lose a group of customers.

  In Wang Qi's view, this matter is easy to solve.

He recommended "Enterprise WeChat" to his boss. On "Enterprise WeChat", the business docking process between salespersons and customers will be managed. When salespersons leave, they only need to transfer accounts to save customer resources. .

  "This is an application of the industrial Internet platform in management." Wang Qi said that in the production process, the industrial Internet platform is more useful.

  For a long time, a washing equipment manufacturer has been plagued by a problem: how to deal with urgent orders?

"Originally, the production line was orderly, and an urgent order came, which could easily cause confusion in production," said the person in charge of the enterprise.

  This happens to be a problem that industrial Internet platforms can solve.

Wang Qi and his colleagues connected the company's equipment to the cloud platform. In this way, the production status of each equipment was finely managed.

Once there is an urgent order, the cloud platform will use optimization algorithms to decompose the tasks and assign them to appropriate production equipment without disrupting the original production plan.

  The cloud platform also visualizes the production process, and managers can view the equipment operation status and order progress in real time through the computer screen.

The person in charge of the enterprise can visually see the production situation of the entire enterprise by simply turning on the phone.

  Wang Qi introduced that, up to now, Tencent Cloud (Zhangjiagang) Industrial Cloud Platform has realized 207 enterprises on the cloud, provided 69 enterprises with "industrial Internet + safe production" solutions, and provided lightweight SaaS ( Software as a service) tools.

  Liu Min, a prefabricated construction worker——

  Build a house like "building blocks"

  It only takes 6 days to assemble a building, and it only takes 5 months to build a building. A single building requires no more than 50 people...Although he has participated in prefabricated construction projects for more than a year, for Liu Min, this The construction efficiency of new building technology often refreshes his understanding.

  Liu Min, 36, is the person in charge of the Nanjing New Town Jiayuan Project of China Railway Electrification Bureau Group, and is also a prefabricated construction worker who is "half way home".

  A year ago, Liu Min was mainly engaged in the production management of the construction site. All the projects he participated in were constructed in traditional methods. Liu Min admitted frankly that his understanding of the prefabricated construction technology at that time was still at the theoretical stage.

  Because he didn't have any experience, Liu Min was in trouble when he received the prefabricated construction task of Xincheng Jiayuan.

"Although there are concerns, people always have curiosity. This is especially true for people with technical backgrounds like me. When I see new crafts, I think I must try it if I have the opportunity." So Liu Min gathered his courage and took it. This job.

  Liu Min learns while doing.

He bought a lot of books and materials, practiced operations with his colleagues on site during the day, recalled the content of the day homework at night, found places in the books, and explored the principles.

This cycle went back and forth for several months, and Liu Min finally found the way.

  So, what are the characteristics of prefabricated building construction?

Liu Min explained that repairing prefabricated buildings is like "building blocks". Components such as boards and walls are "building blocks" that need to be prefabricated in the factory in advance, and then transported to the site to be spliced ​​according to the design drawings.

  Compared with the more arduous working environment of traditional construction, the cleanliness advantage of fabricated construction is more obvious.

Liu Min said: "The use of prefabricated construction can greatly reduce on-site wet operations, reduce dust, waste gas and wastewater discharge, and reduce the number of construction personnel, avoiding many potential safety hazards from the source."

  In fact, although prefabricated building construction is not accompanied by large machinery all the year round like traditional buildings, it is by no means a simple splicing. A small deviation may have a serious impact on the quality of the building. Liu Min understands this Quite deep.

  Each building of the Xincheng Jiayuan project has 24 floors, but the traditional construction method is still needed for the lower than 5 floors, earthwork is excavated, and the frame structure is constructed by cast-in-place shear walls.

If the two different processes want to achieve the same architectural effect, it depends on the bonding transition of the "conversion layer (5th layer)".

  “Therefore, the vertical steel bars used on the fourth floor and the vertical steel bars of the precast shear wall on the fifth floor must come from the same manufacturer, so that the connectivity of the conversion layer can be guaranteed.” Before construction, Liu Min repeatedly explained to the manufacturer, But unexpectedly, during the trial production of prefabricated components, there was still a problem of incorrect steel bar factory standards.

Thanks to the timely discovery, excessive economic losses and waste of resources were avoided.

  In order to ensure that such incidents do not occur again and strictly observe the quality of component production, under Liu Min's suggestion, the manufacturer deliberately designated a group of workers to be responsible for the production of prefabricated components for the Xincheng Jiayuan project.

"In addition, I also arranged a special person to be in the factory to monitor and control, and there was no similar error since then." Liu Min said.

  Now, with the joint efforts of Liu Min and his colleagues, the main structure of the first residential building of the project has been successfully topped off on November 14. It is expected that the Xincheng Jiayuan project will be completed in December next year.

  "After this project is over, I will summarize the management experience of the whole process into a book and share it with people around me to help more people understand and master the new technology of prefabricated construction." Liu Min said confidently.

  Long Changxin, a drone installation and maintenance worker——

  This "doctor" is a tech junk

  "The inspection has been completed, you can take off!" Scan the fuselage, turn the blades, and check whether the wiring is loose... After the drone installation and repairer Long Changxin issued a safety instruction, a logistics drone quickly lifted off for 20 minutes Later, it landed smoothly at the SF Express Distribution Center in Nankang District, Ganzhou, Jiangxi, and successfully transported the Gannan navel oranges to the destination.

  In order to help win the battle against poverty, SF Express built a drone base in Nankang District in June 2017 to try to explore "drone + navel orange transportation".

However, Nankang District is located at the junction of Luoxiao Mountain and Dayu Mountain. The climate is humid and the environment is complicated. In order to ensure the safe flight of UAVs, Long Changxin did not bother much.

  Speaking of his career choices, 44-year-old Long Changxin said that it was entirely a matter of interest.

“I’ve been very obsessed with aircraft models since I was a child. For me, playing model aircraft is more like realizing my “flying dream”.” Through self-study and online education, Long Changxin has accumulated a lot of experience in model aircraft production and maintenance. Soon he became a well-known "aircraft enthusiast" in his hometown.

  In 2012, an agricultural technology company sent an invitation to Long Changxin, asking him if he was interested in operating a plant protection drone.

"There are many drones comparable to aircraft models, which immediately aroused my interest." In this way, Long Changxin became a professional pilot and officially set foot in the field of drones.

  In the UAV industry, "three-point flight and seven-point repair".

Because the machine is expensive, the maintenance of drones is very important.

"In engine maintenance, manufacturers often only provide remote guidance, so our pilots must have excellent hands-on capabilities." After going back and forth, Long Changxin, who has been "healed for a long time", has mastered the professional drone repair technology.

  With proficient drone repair skills, Long Changxin successfully joined SF Express in August 2017 as the head of the maintenance department of the drone base in Nankang District.

However, the drone industry at that time lacked standardized maintenance guidelines. When determining each maintenance standard, Long Changxin and his team members "crossed the river by feeling the stones."

  The most memorable thing for Long Changxin is to determine the UAV maintenance cycle.

Due to the lack of sufficient data, Long Changxin led the team to conduct many flight tests under different environmental conditions in order to accurately define the maintenance cycle of each component.

"When testing in the field, people often climbed over mountains and mountains under the scorching sun and carried various equipment. After a few months, regardless of physical or chemical sunscreen, it didn't work. Everyone lost several layers of skin. "Long Changxin told reporters that they finally overcame the difficulties, positioning and tracking multiple models and various components, and establishing an accurate and complete drone maintenance cycle.

  Long Changxin is a technology junkie.

Since some failures of the UAV cannot be detected by visual inspection, hand inspection and touch, Long Changxin also actively cooperated with the UAV R&D team to iteratively upgrade the related maintenance system and equipment.

"Through background query or batch export of data, maintenance personnel can realize fault classification and fixed-point investigation, which greatly improves work efficiency." Long Changxin said proudly.

  At present, the application field of drones is still expanding. According to the Ministry of Human Resources and Social Security, the demand for drone assembly and maintenance workers will reach 3.5 million in the next five years.

UAV assembly and maintenance workers are officially classified as a new occupation, which will undoubtedly provide professional skills support for the rapid development of the UAV industry.

  "Unmanned aerial vehicle assembly and maintenance workers are included in the National Occupational Classification Catalogue, which fully demonstrates the national level of recognition of our profession." Long Changxin said that in the future, he will work harder to study technology to escort drones for safe flight.
