by The cool technology seen by vision is not the demand of digital chemical plants.

In terms of production, the unique QR code technology of each component can be used to record the whole cycle production process of the component online.
The acceptance standard and rectification process of each component are clear and can be queried and replied in the information system, which greatly improves the communication efficiency and rectification efficiency between production and quality inspection departments, and prevents unqualified products from flowing into the storage yard or even into the site.

To put it simply, “digitization” is to transform many complex and changeable information into measurable numbers and data, then use these numbers and data to establish an appropriate digital model, convert them into a series of binary codes, introduce them into the computer for unified processing, which is the basic process of digitization.
The ultimate goal of adopting digital solutions is to enable component factories to obtain real benefits..
Moreover, due to the poor information between the factory and the site, component factories often pile up components in the storage yard due to the delay of the construction site, which affects the production of other projects 3 – how to realize digitization of component factory? At present, if most prefabricated component factories want to realize digitization, there is a big gap compared with advanced digital cases such as Siemens.
Further, if it is connected with the information system on the project site to realize data sharing, the factory can adjust production according to the real-time construction situation on the site and release the production capacity of the factory to the greatest extent.
There is still much room for improvement in the appearance quality, manufacturing accuracy and internal quality of precast components.
Therefore, from the perspective of the current industry informatization, investment cost and implementation, the first step of digitizing the prefabricated component factory is to realize the tabulation, process and standardization of factory operation, establish a data-driven, flexible and configurable multi platform real-time collaborative system, so as to improve production efficiency, reduce manufacturing cost, open up the information island and truly realize the informatization management of the component factory.
In terms of production, at present, the production management mode of many component factories is not standardized, the on-site production process management is not standardized, the procedures are chaotic, the plan achievement rate is not high, and the production efficiency is low.
It basically adopts the traditional paper management mode, which has poor efficiency.
The solution of digital chemical plant not only creates value for component factories with its characteristics of fast, efficient and flexible, but also helps component factories open up information islands, effectively realize integration and interconnection, and lay a good foundation for component factories to become intelligent in the future.

In addition, the warehousing logistics is chaotic, and the board cannot be found during delivery, resulting in endless re production.

The German Institute of engineers defines digital factory as: Digital Factory (DF) is an integrated network composed of digital models, methods and tools, including simulation and 3D / virtual reality visualization, which is integrated through continuous and uninterrupted data management.
The system can monitor the production beat, production progress, daily production plan achievement rate and output in real time.
In terms of logistics, at present, the storage yard management of prefabricated component factory has a low degree of informatization.
Although the number of factories has increased, the product quality has not improved much; In addition, the serious absence of quality management in construction enterprises restricts the quality improvement and promotion of prefabricated components.

However, due to the lack of operation experience of PC factories by the construction party, the problems of emphasizing investment and construction and neglecting operation management are common in new PC factories.
In terms of quality, the overall quality level of precast concrete building components in China is still low.
Click the “blue word” at the top to focus on more highlights – 1 – what is a digital chemical plant? In recent years, digital chemical plant has gradually become the focus of enterprises, and the specific practice and application have also achieved rapid development.
In terms of quality, an online quality acceptance process is established.
Digital chemical plant integrates product, process and plant model database, and improves product quality and quality and dynamic performance involved in production process through advanced visualization, simulation and document management 2 – general situation and management problems of component factories according to the development report of precast concrete component industry in 2020 issued by China concrete and cement association, the number of precast concrete component manufacturers in China has increased rapidly in recent years.
Because of the low degree of automation, the serious dependence on manpower and the lack of intelligent equipment, it is difficult to achieve that degree without huge cost.
Production records generally rely on traditional paper records, and special personnel are required to count and summarize them every day.
In terms of logistics, we abandon the traditional paper management mode and use the two-dimensional code technology mentioned above to accurately record the component position when warehousing, and quickly find the board when delivery is needed, so as to improve the delivery efficiency.
Quality, efficiency and flexibility are the main problems faced by component factories in the fierce market competition.
However, the interpretation of the meaning of digital chemical plant is very different, and there is no unified understanding so far.
It can also be automatically calculated and summarized on the large screen of the workshop in real time without special statistics.
They are also the three challenges faced by component factories to move forward to intelligent manufacturing and finally realize the vision of industry 4.0 through the road of digital transformation.

On the one hand, due to the weak quality management foundation of prefabricated component factories, the employees are mainly transformed from construction and building materials enterprises, and lack of training and experience in modern industrialized manufacturing; On the other hand, there is a shortage of technical management personnel and industrial workers, and workers are inexperienced.
