Abstract: Economic development cannot be separated from the support of technology. In recent years, the continuous development of our country's information technology and science and technology has provided a greater contribution to economic development and market expansion. In the current momentum of technological development is so rapid, the development of electrical automation technology is more significant, and in its technical categories, PLC technology is very important for the smooth development of the project is of great significance. The use of this technology is mainly through its high stability and practicality, the scope of use gradually expanded, in the development of electrical automation, the use of this technology has a more obvious advantage, so this paper through the significance of PLC in electrical automation control and specific applications are analyzed to promote the effective use of this technology.
Key words: PLC; Electrical automation control; Specific application
In the actual operation process of enterprises, the corresponding production operations will promote the development of industrialization, which has a positive effect on the stability of social production and living operations in our country. In the actual production process, more advanced technologies and production processes will be used to improve production efficiency. Safety in the production process will also be improved. At this stage, the use of electrical automation technology is more common, and relevant technicians have gradually conducted in-depth research on the use of this technology, through the use of PLC technology, to promote the rationalization of the use of automation technology, in order to improve the use of automation technology efficiency and use quality, which has a positive effect on the production of enterprises.
First, the significance of the use of PLC technology analysis
(A) On the use of electrical equipment capacity expansion analysis
In essence, PLC technology belongs to an application technology under the control of computer technology, mainly based on computer technology, and there are also some memory in its structure, through the optimization of some data software in the system, so as to achieve the effective use of technology . In this process, the relevant data is stored, so the amount of data in the system will gradually increase. At the same time, after the storage of historical data, the amount of data in the system will be increased, and the failure of the system can be more effective processing, and this technology in its actual development process, increased the relevant functions of the control unit, and achieved better production results in most industrial fields.
(2) Intelligent analysis of electrical equipment
This technology in the use of electrical automation process, can improve the efficiency of automation system, and can promote the intelligent development of automation control system, this process will gradually improve the level of automation control. The use of PLC technology is mainly reflected in the system software for the good control of system data, and through the combination of specific use procedures to improve the production more effectively, and this technology can also carry out substantive innovation and improvement.
Second, the specific application analysis of PLC technology in electrical automation system
(A) About the application of numerical control system analysis
At this stage, the main development direction of China's industrial production is automation and intelligence. Therefore, through the analysis of this direction, relevant technicians build and improve the use of equipment, and strengthen the use of PLC technology in the actual operation process . Now the use of numerical control systems, mainly based on PLC technology is mainly divided into the following types: point control system, linear control system and continuous control system, combined with China's actual production development requirements, related enterprises in the production development process, need to have a comprehensive function of the numerical control system to be used, in order to improve the production efficiency of enterprises.
These systems in the construction and improvement of the process of the use of technology has the corresponding rationality, through the actual production practice analysis, this device equipment in the actual promotion process is more functional, and technical is also strong, so its specific R & D investment cost is higher, at this stage, still can not carry out large-scale R & D use. Based on this situation, the use of PLC technology to establish the corresponding data system, in the actual operation process, the corresponding circuit problems can be avoided, to promote the optimization of CNC production equipment, to achieve effective adjustment, so that the flexibility of the enterprise in the actual production process will be increased .
(2) Application analysis of highway traffic system
With the development of the economy, the continuous progress of society, and the accelerating process of urbanization, the pressure generated by traffic in our country is gradually increasing, so the relevant technical personnel need to rationalize the use of PLC technology in response to this problem, achieve effective promotion, and alleviate the traffic pressure at this stage. By using PLC technology as the basis of the system, it has strong adaptability in the actual operation, and can be widely used in the traffic system. Relevant technicians use this technology, mainly for the electrical system in the traffic system, the use of this technology is more significant, for the control of traffic lights has a positive effect, through the use of this technology can realize the intelligent control of traffic lights, improve the quality of management.
(3) Analysis of switching quantity control
In the previous working mode, relevant staff need to use the electromagnetic machine to control the switching quantity, which will lead to a more complex state of the line, and in the actual operation process, the number of nodes will be more, which is not conducive to the stability of the control, there are large restrictions, and there will often be corresponding failure problems. The operation efficiency of the equipment is also difficult to improve . In response to this problem, technicians have improved and innovated the use of relays to gradually reduce the use of relay failures. In this process, the use of PLC technology to achieve more effective control of the switching quantity, greatly improve the quality of operation, the use of open circuit display to effectively maintain the system, promote the automatic control of system operation, expand the scale of development of the project.
(4) Application analysis of monitoring system
In view of the use of this system, the PLC technology as the core of this monitoring system, in the mining process, the use of electrical equipment can be strictly monitored, through the use of PLC technology to meet this requirement, in the process of air compression, to achieve monitoring, the problem to be found in time, through the collection of relevant data, This ensures the accuracy and practicability of the data in this link .
The use of PLC technology has obvious advantages, and its high stability in the use of different systems, high adaptability, in the field of electrical automation system use, gradually expand the scope of use, and different from the traditional control technology, the use of this technology can achieve the optimization of production structure, improve production efficiency, reduce production costs. Therefore, based on this situation, relevant technicians need to carry out corresponding research and development, in order to improve the control level of electrical automation, improve production efficiency, and increase the economic benefits of enterprises.
