Editor's Note
Comprehensively promoting the digital transformation of cities is a major strategy determined by Shanghai's 14th Five-Year Plan, and it is also a future-oriented shaping of the city's core competitiveness. In the next five years, Shanghai will make an overall transformation and promote the comprehensive digital transformation of "economy, life and governance".
The action plan for promoting the digital transformation of Shanghai's economy and empowering high-quality development (2021-2023) pointed out that by 2023, Shanghai will be built into a world-class innovative industrial agglomeration area, a demonstration zone for the integration and development of digital economy and real economy, a leading area for ecological construction of economic digital transformation, and a model city for international innovation and cooperation in the digital economy. From now on, the Shanghai Municipal Economic Informatization Work Party Committee, the Shanghai Municipal Commission of Economic Informatization and the People's Online Hai Channel will cooperate to focus on the digital transformation of Shanghai's economy, launch a series of new concepts, new technologies and typical examples of new models with benchmarking and demonstration effects, create a Shanghai practice of urban digital transformation, open up a new track to enhance Shanghai's urban soft power, and run out of the acceleration of Shanghai's high-quality industrial and informatization development.
Xiao Zhang is a salesman of a company, received a new order, clicked a mouse, dragged a few times, the 3D model on the factory customer service platform was displayed, and the order was placed without a problem. After the factory receives the order, the internal began to circulate, the system prompts, mobile phone reminders, workshop kanban scrolling display, the process can hardly see the paper in the transfer; what the factory is producing, how much has been completed, whether the material procurement has arrived, all this, Xiao Zhang can also see clearly on the computer side.
Inside the factory, the workers are busy, all this is watched by the "eyes" on the side, who do not wear hard hats, who enter the forbidden area, who do not wear protective masks... Warning lights are lit, always reminding them to pay attention to safety.
Intelligent control of production safety
Before shipment, Xiao Zhang came to the factory, only to see him "pointing fingers", it turned out that he was wearing AR glasses to explain to customers on the other side of the ocean, and the customer was directing him to look at this and that, just like that, the acceptance of products worth millions of dollars was completed. And such a multi-chain intelligent application scenario, Astronergy Group's power and energy equipment intelligent factory can all be "taken".
5G + Virtual Site Acceptance (AR/VR)
Data interoperability enables production management
Innovation in models and approaches
Li Wei, head of the information department of Chint Group, introduced that to build a smart factory, it is necessary to gather four "dragons".
1
First, it is necessary to automatically control the post-production and service management links, "just like the control of human organs, enterprises develop and run ERP\MES\CRM and so on";
2
Second, open up the transmission path of information, "just like the nerves of people and the second pulse of Ren, enterprises need to apply 5G and industrial Internet platforms";
3
Third, simulations and simulations are needed to produce optimal control tools and decisions, "as if a person thinks and makes a decision";
4
Fourth, it is necessary to build a digital central control center that stores a large amount of data and has computing and analysis functions, "this part is the human brain, and for the enterprise, it is the construction of the data center." ”
Intelligent manufacturing integration platform
So, why build such a smart factory for electric energy equipment?
Li Wei said that from the national policy level, this is in line with the transformation from extensive manufacturing with large resource consumption and pollutant emissions to green manufacturing in recent years and the general trend of transformation from production-oriented manufacturing to service-oriented manufacturing; from the perspective of emerging technology development, the rapid development of emerging technologies such as mobile Internet, big data, and cloud computing has increased the process of deep integration with manufacturing equipment; and based on market requirements, smart factories have the advantages of low cost, high quality, short production cycle, and timely service response From the perspective of its own industrial development, the intelligence of equipment manufacturing and the intelligence of transmission and distribution equipment itself will become the core competitiveness of the industry in the future.
"The production management mode of each product line of Chint Electric in the field of power transmission and distribution belongs to the order-based production mode driven by market sales." Li Wei said that the power energy equipment intelligent factory relies on various information systems to ensure timeliness and effectiveness, and realizes intelligent management in all aspects.
"Since the vast majority of market orders belong to power engineering construction projects, the process of production and manufacturing is also controlled according to the project orders. Therefore, the diversity of market demand and the particularity of products and the existence of a large number of special-shaped parts, so that the company manufactures more than a thousand kinds of parts, of which only a few small batches, but the batch can be as many as tens of thousands of pieces, the production mode presents a multi-variety, single, small and medium-sized batch, large batch and other production modes coexist. In this case, how to form a digital and intelligent control system in the company to meet the personalized customization requirements of customers has become one of the key links to solve the company's manufacturing problems. ”
At the basic level, the digital networking of equipment connects devices and enables systems and devices to be interconnected. At the system level, meS (Manufacturing Execution System), APS (Advanced Production Scheduling), WMS (Warehouse Management), Energy Management, Quality Management and other industrial software are applied. At the level of management methods: the use of industrial engineering, lean manufacturing, to achieve order-driven, pull-based production, reduce inventory, eliminate waste.
The core application architecture of the smart factory
"In this way, the production process to achieve transparent management, a variety of situations at a glance, the manufacturing process is more secure and reliable, not only that, manufacturing data visualization, but also for rapid decision-making analysis, no need to report layer by layer, in addition, to achieve paperless documentation, reduce transmission time, save paper while achieving green manufacturing." Li Wei said.
In other words, the promotion of technologies such as big data collection and analysis has laid the foundation for integrated digital design and production management, strengthened the interconnection between industrial manufacturing enterprises and customers, and the data exchange between various departments and workshops within the enterprise, between the production and manufacturing layers and the management scheduling layer, and finally realized the innovation of production management models and methods based on the industrial Internet.
"According to the large product span and different production cycles, different types of automation equipment are introduced, eliminating the "islanded" production method, meeting the production requirements of multiple varieties and small batches, improving the automation, digitization, networking and intelligence of the manufacturing process, and realizing the 'one flow' of the production process." Li Wei said.
Digital intelligence empowers the transformation and upgrading of the industrial chain
In 2003, in response to the strategic deployment of "actively integrating with the Yangtze River Delta and integrating into greater Shanghai", Chint Group put forward the overall development strategy of "connecting with the Yangtze River Delta and building an international advanced electrical manufacturing base", invested 3.5 billion yuan in Songjiang, the southwest gateway of Shanghai, registered and established Chint Electric Co., Ltd., and built a new transmission and distribution industry base covering an area of 1350 acres, which opened the prelude to a comprehensive march into the high-voltage power equipment manufacturing industry.
After nearly 20 years of hard work, Chint Electric has realized the transformation and upgrading from medium and low voltage voltage level products to UHV voltage level products, from "selling products" to "selling services", from simple product manufacturing to system integration turnkey transformation and upgrading, from traditional manufacturing to "smart manufacturing" transformation and upgrading, in 2020, the sales scale has reached 10 billion.
With a new round of global scientific and technological revolution and industrial transformation, digital technologies such as mobile Internet, cloud computing, big data, Internet of Things, artificial intelligence, and blockchain have had a huge impact on all walks of life. The deep integration of digital technology and traditional manufacturing industry is the trend of the times, and how to achieve the transformation and upgrading of the industry with the help of the east wind of digital technology has become one of the important tasks we need to actively explore and study.
At the end of 2018, Chint Electric began to launch digital transformation, planning to spend three to five years, guided by the Group's "one cloud, two networks" strategy, with digital construction as the main line, through the construction of core digital platforms such as marketing platforms, research and development platforms, supply chain platforms and operation support platforms, linking customers and suppliers for digital integration, to achieve accurate and rapid docking of customer needs, digital marketing and design, intelligent production and services, and comprehensively build the ability of enterprises to "connect users" and "build good products" Competence, the ability of "intelligent supply chain".
Chint Group's "one cloud, two networks" strategy
The application of power transmission and distribution business has landed
"Key areas of 'new infrastructure' such as 5G, artificial intelligence, industrial Internet, and Internet of Things will become an indispensable industrial demand for China's economy to achieve high-quality development."
In January 2021, Shanghai issued relevant opinions on promoting the digital transformation of cities, proposing to promote digital transformation in industry, life, and social governance.
Next, Chint Electric will, as always, take the initiative to dock and implement the digital development strategy of the national and municipal governments, make full use of the most cutting-edge digital technology to reshape management and industrial form, realize industrial transformation and upgrading, promote the high-quality development of the transmission and distribution manufacturing industry, help the digital transformation of the G60 science and technology innovation corridor in the Yangtze River Delta, and promote the common promotion of digital industrialization and industrial digitalization of the G60 science and technology innovation corridor.
