introduce
The development of electrical engineering automation in China started later than that in developed countries, but because of its wide applicability, it has been welcomed by all fields of society and constantly put forward new requirements for electrical engineering automation. In order to adapt to social changes and meet people's constantly updated needs, electrical engineering related units need to optimize the design and application of electrical engineering automation.
First, the principle of electrical engineering automation design
1。 1。 Improvement of equipment operation efficiency
The operation efficiency of equipment is a key consideration in the design of electrical engineering automation, and ensuring its operation efficiency is one of the principles of electrical engineering automation design. Therefore, in the automatic design of electrical engineering, we must first ensure the safe and stable operation of heavy electrical equipment in buildings, and on this premise, reduce the design cost as much as possible; Secondly, in order to improve the utilization efficiency of electrical equipment, minimize the damage of operating equipment, reduce the possible equipment maintenance costs and the overall cost of electrical equipment, when installing electrical equipment automatically, try to choose equipment with higher quality, better energy-saving effect and more balanced load.
1。 2。 Optimization of electrical engineering automation design
The optimization of electrical engineering automation design is one of the important principles of electrical engineering automation design, so scientific and reasonable design is a very important work in electrical engineering automation installation. The optimization of electrical engineering automation must first meet all the requirements of the owner for electrical equipment and maximize the overall stability, reliability and safety of electrical automation. In addition, electrical engineering automation is a system engineering 1, and its operation requires a lot of high-tech equipment, which is very complicated. Therefore, to ensure the overall safety of electrical engineering operation, we must first ensure the safety of these equipment, which requires the automatic installation of electrical equipment, and the installation requirements of these high-tech equipment are generally special and complicated, such as lightning protection, fire prevention, waterproof and so on.
Second, the practice of electrical engineering automation
2。 1。 Guarantee of reliability of PLC control system
Because PLC control system is one of the important ways to realize electrical engineering automation, the reliability of PLC2 system is very important to ensure the quality of electrical engineering automation. The reliability of PLC system is mainly ensured by improving its anti-interference, and its anti-interference is mainly realized from the following aspects: (1) In terms of PLC installation and wiring, firstly, the wiring of PLC control system should be far away from high-power devices and large-scale power equipment, and it should not be installed in the same cabinet with high-voltage electrical appliances. In order to avoid the interference of external signals, input and output lines, switching values and analog values should be laid separately. Among them, AC and DC outputs should be separated and not connected in parallel, and should be far away from high-voltage lines and power lines. (2) A good grounding scheme can also ensure the safe and reliable operation of the PLC system. Generally, there are three grounding methods: floating ground, direct grounding and capacitive grounding. These three methods have their own advantages and disadvantages, and they can be selected according to the actual situation of this project. (3) There are many ways to improve the reliability of PLC system, such as hardware measures such as the treatment of its power supply and inductive load. But this can't completely eliminate the interference, and some software measures can be taken to improve the anti-interference.
2。 2。 Pay attention to the cultivation of comprehensive talents
The core of competition in 2 1 century is actually the competition of talents, so if you want to regain a foothold in the highly competitive electrical engineering industry, you must pay attention to the cultivation of comprehensive talents, which is also one of the important strategies to realize electrical engineering automation. First of all, basic professional knowledge and skills must be included, especially in the gradually automated electrical industry. Staff must be able to understand the basic working principles of intelligent building automation systems in detail, such as lighting, air conditioning, elevators, ventilation, fire fighting, etc., so as to realize effective control of these systems and ensure the smooth and safe operation of system equipment. First of all, electrical engineering related units should organize employees' professional skills training, or provide employees with conditions and opportunities for learning and further study, which can not only greatly improve the professional quality of employees, but also retain talents and enhance the competitiveness of the industry, thus promoting the development of electrical engineering automation. Secondly, the relevant personnel engaged in electrical work should constantly update their professional knowledge, because in this fast-developing society, with the role of science and technology, many new technologies, new processes and new equipment appear and update quickly, especially for electrical engineering automation. Therefore, electrical engineering personnel should always pay attention to the information of the electrical industry and learn the latest professional skills in time in order to keep up with the pace of social progress and become all-round talents.
2。 3。 Combining modern high-tech technology to realize electrical engineering automation
To realize the automation of electrical engineering, it is necessary to use modern high-tech and advanced measurement experiment technology, such as electronic engineering practice, microcomputer control, EDA experiment, single chip microcomputer technology and so on. Design experiments and training to improve the scientific research, practice and innovation ability of electrical workers. Of course, enterprises also need to train employees in microcomputer control and electric drive, and use these high-tech experimental technologies to ensure the automation of electrical engineering. In addition, the automation system can also use advanced technology to record its comprehensive operation flow and fault treatment in time, and establish a clear database, which is conducive to the later optimization. For some special needs, special systems can be established, such as parking lot management system and smart home service system.
2。 4。 Strengthening automation management of electrical engineering
Effective management is essential for the smooth operation of any system, and so is the automation of electrical engineering. In practical work, KVM, CATS and other modes can be used to establish the link between the equipment and the control room. 4. Through a relatively perfect digital control system, the dual management mode of local control and remote control can be realized.
Third, the development prospect of power engineering automation
In order to further realize the automation of electrical engineering, all electrical engineering-related enterprises should make scientific and reasonable development plans, effectively use all available resources, innovate constantly, open up a good market, improve their competitiveness and increase the economic benefits of enterprises, thus promoting the rapid development of the electrical industry.
3。 1。 Promote the unification of the system
As the basis of promoting the development of electrical engineering automation, the unity of the system can effectively shorten the time of product design, product production and product installation, and greatly reduce the cost, because it can periodically plan and design related products, accurately test and test products, and is conducive to product start-up, debugging, operation and maintenance. In order to realize the separation of electrical engineering from electrical engineering operation system for development and design, meet the actual needs of owners, and realize the unified management and generalization of electrical engineering automation, it is not necessary to promote the unification of electrical engineering automation.
3。 2。 The interface is further standardized.
In order to promote the communication and sharing of resources and data between the actual office system and the electrical engineering automation system, reduce the actual cost of electrical engineering and reduce the implementation time of electrical engineering, standardized interface is one of the effective measures to achieve this goal. When the electrical engineering planning scheme is far away from the realization place, it is also the premise to ensure accurate data transmission. Generally speaking, to realize the data exchange between manufacturers, the unification and standardization of interfaces is an important guarantee, which is of course one of the urgent problems faced by electrical engineering automation.
Concluding remarks
In a word, with the gradual improvement of people's requirements for living and working environment, function and quality, the state and enterprises pay more attention to electrical engineering automation. When designing electrical engineering automation, relevant units should pay attention to strictly abide by relevant laws, regulations and design principles to ensure the safety and stability of electrical engineering automation. At the same time, we should make full use of modern high technology, pay attention to the management and control of engineering projects, and increase good economic and social benefits for the society.
