With the increasing attention to the application of electrical engineering technology from all walks of life, China's industry has entered a stage of rapid development, which is of great significance for promoting China's comprehensive national strength and overall improvement of international competitiveness.

Common industrial electrical engineering automation control problems

Energy conservation

Although China's social and economic development has achieved remarkable results in recent years, there is still a big gap between the energy consumption per unit of GDP and per unit of industrial added value compared with developed countries. Energy has become a major issue affecting social and economic development. At the same time, in order to ensure the smooth realization of the strategic goal of sustainable development, China has also increased the publicity and promotion of energy-saving and emission-reduction technologies. As the main energy consumption system in China, electrical engineering plays an important role in energy saving and emission reduction. Many enterprises only consider the realization of electrical functions in the construction of electrical engineering. In order to reduce the investment in the initial construction, they excessively choose low-cost equipment with backward technology and high energy consumption, but ignore the long-term energy consumption.

Quality and management issues

The construction quality is the soul of the whole electrical system. The quality of construction is directly related to the stability of the whole system in the later period. Only by increasing the investment in the quality and management of electrical engineering can we ensure the long-term and stable development of electrical engineering. However, because most construction enterprises excessively pursue the economic benefits of construction and blindly pursue the construction schedule, they neglect to grasp the construction details. In the process of project acceptance, it is usually just for the completion acceptance, or stage acceptance, and the supervision is less in the construction process. Detail decides success or failure, electrical construction, especially, in the process of construction, small mistakes when acceptance is usually not easy to find, in the initial run time is not easy to expose, is often as the equipment running in the middle of the late operation gradually revealed, such as a small connection screw loosening caused by increased contact resistance, may cause paralysis of the entire system and even cause a fire.

Poor system integration

With the large-scale, large-scale and high-parameter industrial production, PLC, DCS, various intelligent instruments and sensors are widely used in industrial electrical automation systems. However, due to the differences in construction time and manufacturers, many electrical automation systems show a state of separation due to the influence of many factors such as different interfaces, different platforms and different programs, which brings a lot of inconvenience to the collaborative work among systems and the management and operation of operators.

Measures to solve automation control problems in electrical engineering

Train managers' consciousness of energy saving and optimize energy saving design

Energy conservation is a key link for sustainable development of enterprises. As a decision maker, it plays a key role in the development of enterprises. Therefore, it is necessary to establish an overall awareness of energy conservation, actively learn EMC, BOT, PPP and other operation modes, carry out energy conservation technology discussions, regularly invite relevant energy conservation experts and enterprises to carry out energy conservation diagnosis, and formulate energy conservation design schemes. We will make full use of advanced technologies to recycle waste heat and pressure, and adopt green lighting technology, frequency conversion technology and other advanced technologies to reduce energy consumption. Qualified enterprises can build energy management center and other use of digital network management platform to facilitate data management.

Strengthen engineering quality process control and improve management level

As a construction enterprise, we must realize the importance of quality management, strengthen the sense of responsibility, and comprehensively improve the management level from the management team, construction team, material inspection and other aspects. First of all, the team responsible for the construction and maintenance of electrical automation engineering must have extremely high professional skills and quality. The enterprise should strictly select the members of the electrical automation team and conduct systematic training to improve the professional ability of the electrical automation team. Secondly, in the construction process, the materials used must be carried out strict quality inspection. At the same time, it is necessary to formulate the construction specifications of each process, establish a multi-stage inspection system, and ensure the construction quality by means of regular sampling inspection and regular inspection.

Develop enterprise-level data sharing mechanism and establish standardized communication interface

With the expansion of production scale and the increasing variety of automatic control systems, these systems are often impossible to be built by a single company. Although many vendors are now offering a wide variety of international standard interface module, but because of the different manufacturer equipment standards are not consistent, or to the system integration work has brought a lot of inconvenience, therefore make the enterprise internal data sharing mechanism, such as Microsoft technical standard system of electrical automation based on information platform and communication as the standard with TCP/IP, on electrical automation platform to establish a standard programming interface, so as to achieve effective solve the problem of poor communications, as a result of different type products, promote the electrical automation system to run effectively improve efficiency and quality.

Electrical automation control technology development trend

With the rapid development of computer technology, information technology and artificial intelligence technology, electrical automation control technology is also developing towards the direction of specialization, intelligence, distribution and Internet of things. Among them, standardized interface design is the basis of realizing automatic data resource interaction and sharing, which can greatly reduce the working time of system integration and improve the stability of the system. The development of artificial intelligence technology to the development of electrical automation control technology provides a powerful intellectual support, intelligent technology in comparison with traditional automatic control technology, it not only saves the designing model of the complex part in electrical automation control, but also reduces the external uncontrollable factors on the impact of electrical automation control system, promote the effective improvement of electrical automation control precision.

conclusion

In short, industrial electrical automation control technology is the direction of modern industrial development, the level of development of industrial electrical automation control technology affects the level of a country's scientific and technological level and the level of industrialization. In the new era of the development of socialist market economy, the development of industrial electrical automation has entered a new stage, there are more and more lightless factories and cloud factories. Industrial electrical automation is also contributing more and more to society. With the concept of German industry 4.0 and made in China 2025 proposed, it is believed that in the near future, industrial automation will usher in a new world of development.
