Factory automation refers to the automatic control and operation of the production process through automation equipment, automation systems, automation software and other technologies in the factory production process, so as to improve production efficiency, reduce production costs, and improve product quality. The realization of factory automation requires technical support in many aspects, including sensor technology, control technology, communication technology, computer technology, etc.
It is an inevitable trend for manufacturing factories to achieve automation, but now the level of automation in many manufacturing factories is not as popular as people think.
1. BOE "Lighthouse Factory".
The "Lighthouse Factory" is known as the "world's most advanced factory" and is an exemplary "digital manufacturing" and "globalization 4."0" demonstrator, BOE Fuzhou No. 8The 5th generation semiconductor display production line was selected as a "Lighthouse Factory", and CET CLP Technology provided CET semiconductor industry power monitoring and management system solutions and supporting power secondary intelligent terminals to help enterprises achieve safety efficiency, management efficiency, carbon reduction and efficiency.
Intelligent O&M realizes rapid troubleshooting and preventive maintenanceThe automatic push of power fault and abnormal information identification and fault handling plans based on "semantic recognition" improves the efficiency of power system O&M and rapid fault recovery, and quickly completes emergency treatment, checks faults and resumes normal production.
Multi-directional monitoring to ensure the continuity and high reliability of power supply, from medium and high voltage power distribution equipment to clean plant process bus and i-line panel comprehensive monitoring and control, to achieve power equipment and process equipment power safety guarantee, to ensure that the enterprise 24 hours uninterrupted production, and to achieve regional unmanned and less people on duty, reduce operating costs.
In view of the high energy consumption of the factory, through the statistical analysis of the electric energy consumption of each plant and workshop, the potential for saving costs is excavated, the energy distribution and balance are mastered, the energy efficiency index assessment system is scientifically quantified, and the flow direction and use of each kilowatt-hour of electricity are mastered, so as to provide a basis for energy conservation and consumption reduction.
In the case of no one or few people on duty, the use of automation to carry out long-term accurate supervision of production, and obtain effective information and data from it, to provide a strong evaluation reference for the supervision of managers, has been recognized by customers and praised by users.
2. Dongfeng Nissan Huadu Factory
Dongfeng Nissan is an important passenger car business sector of Dongfeng Motor Group, with 4 factories in Huadu, including HD1, HD2, DNEC and DNEC-CN, each plant has a power monitoring system, sewage treatment system, refrigeration system, water cold storage system, compressed air system, gas system, water supply and pressurization system, ** monitoring system and other equipment monitoring systems, with a total of 53 sets of systems in 4 plants.
Factories are faced with the problem of improving the efficiency of energy metering: energy data is manually transcribed, summarized, and calculated, which requires more manpower and time, and it is difficult to ensure accuracy.
Therefore, in 2019, Dongfeng Nissan decided to upgrade the monitoring system of Huadu Plant 4 and build a centralized monitoring platform to restore the effective monitoring of refrigeration, air compressor, sewage, power distribution and other systems of each branch, and realize unified monitoring and centralized management, so that information exchange and resource sharing between various professional systems in the plant can improve the efficiency of power equipment operation and management.
Shenzhen CLP Power Technology Co., Ltd. (hereinafter referred to as "CET") provides a full set of software and hardware products, existing system access and new system construction services, as well as construction guidance and commissioning services for the "centralized monitoring project" of Dongfeng Nissan Huadu Plant.
The centralized monitoring system of the power station room of 4 factories has been built, and the system of each factory is connected to the system of each factory (for example, the HD1 factory includes: air compressor system, air compressor number control system, refrigeration system, sewage treatment system, production water supply system, gas system, 10KV power distribution system, 110KV power distribution system, bus temperature measurement system, power quality monitoring system, and ** system).
The centralized monitoring system built by CET can realize the overall monitoring of all plant group equipment, the analysis of overall operation indicators, the overall monitoring of a single factory, the overall monitoring of a single process of a single factory, real-time alarm, alarm query, operation data analysis, etc.
The system not only improves the monitoring effect and operation and maintenance efficiency of each system of the factory, reduces the cost of facilities, personnel and energy consumption, but also improves the overall automation level of the factory, makes the entire production process more transparent, and finally realizes digital management.
In addition, CET has rich experience in the automotive field, and has served Xpeng Motors, JAC NIO, BYD Automobile, Yangtze River Storage, Beijing Integrated Circuit, AT&S and other enterprises, and has been widely acclaimed.
As an important part of modern manufacturing, factory automation can not only improve the competitiveness and development potential of enterprises, but also better respond to market changes and customer needs. It can also improve the working environment of workers and reduce the labor intensity of workers, so as to achieve less manned and unattended, thereby promoting industry 40 development.
