Nowadays, my country's high-tech energy continues to be strong, and relatively obvious results have been achieved in various industries. Especially in the innovation and improvement of electrical automation equipment, the advantages of the PLC control system are used to fill the problems existing in the application of electrical automation equipment and improve the efficiency of the application of equipment. In addition, with the application of this system, the company can control the operation of electrical automation equipment, which has played a great role in the production of the company. In this period of rapid development of high-tech, market competition in various fields is becoming increasingly fierce. In order to gain an advantage in the fierce market competition, the company should continue to introduce high-quality electrical equipment, effectively use current resources, and improve the operating efficiency of machinery and equipment. Safety and stability have laid a good foundation for the company's long-term development.

1. Control product analysis

According to the analysis of the PLC control system, it is mainly composed of two parts, which are data collection and sequence control. In the process of controlling the automatic machinery, the two cooperate with each other and cooperate with the established purpose. This requires that in the process of using the PLC control system, relevant personnel should adopt appropriate operation procedures to determine the main function characteristics of the control system to ensure that the required functions are fully utilized and provide more energy for the company's production. . Among them, the data collection part has various forms of expression, such as graphics, graphs and texts, etc. In this stage, the integration and collection of all data information can be completed, and it can be carried out according to a certain method. Processing, and then transformed into the operation data signal under the process operation, and presented in the above-mentioned way, at this moment, the operator can see the actual processing status of the data more vividly and clearly at a glance, and can be more Quickly grasp the relevant practical operation method. The sequence system is based on the program setting, and further processes the work of the equipment. Before the application of electrical automation equipment, the main parameters and operation methods of the equipment must be entered into the control system. In the actual operation of the equipment, if there is a problem at a certain stage, the system will automatically stop The transmission of data signals realizes the safety operation of equipment. In addition, the alarm device will also respond, in order to remind relevant personnel that the equipment needs to be repaired, and equipment failures should be checked, so as not to affect subsequent operations.

2. Analysis of characteristics in the whole process of PLC control of electrical automation equipment

With the improvement of the country's economic level, PLC technology has gradually attracted more people's attention, and it has played a good role in practical applications. At present, the PLC control system has already existed in various industries in our country, and has become an indispensable element in the production of enterprises. Combining the PLC control system with the electrical automation machinery and equipment further improves the safety factor and reliability of the machinery and equipment application. It helps the company obtain more economic benefits and is conducive to the company's long-term and stable development. In addition, in the process of using the PLC control system, it is also possible to carry out comprehensive monitoring of the entire operation process of the equipment, timely solve the fault problems existing in the equipment, and take appropriate countermeasures to solve them , It has greater advantages in the later maintenance and maintenance of equipment. In addition, with the support of the PLC control system, the work efficiency and quality of equipment maintenance personnel have been improved, reducing the pressure on equipment maintenance personnel, and embodying the application value of this technology. On the one hand, in the application of the PLC control system, the anti-interference performance of the electrical automation equipment is improved. In the actual operation process, the reliability of the equipment is higher, and it can continue to work in a complex environment. In addition, in the With the function of the sequence control part in the PLC control system, it can also realize the detection of the operation status of the electrical automation equipment, which improves the safety factor of the equipment application. On the other hand, the relevant operation of the PLC control system is relatively simple. In the actual application, the operator only needs to set the system program flow, and send commands to the system software according to the company's actual production requirements. Can carry out related practical operation. It can be said that the application of PLC control system has eased the workload of operators, improved the productivity of the company, and provided more assistance in the future development of the company.

3. Analysis of the application of PLC control in electric power automation machinery and equipment

(1) Application of PLC control system in the whole process of sequence control

Compared with ordinary electrical automation equipment, in the actual application process, there are auxiliary systems inside to realize the control function of the operation of the equipment. However, the traditional sequence control method has certain shortcomings in application. In order to fully display the functions of the control system in electrical automation, the company needs to spend a lot of money to purchase power, which is an important expense for the development of the company. Under such circumstances, the problem of resource consumption has become the top priority that companies study in their development. Therefore, in the later upgrading of electrical automation equipment, the use cost should be considered first, and the energy consumption of resources should be minimized as much as possible to achieve the goal of maximizing corporate profits. Nowadays, the emergence of PLC control system has effectively solved the difficulty of resource consumption. With the support of this system, the unilateral control function of equipment can be realized. In this stage, it not only saves a lot of resources, but also improves the efficiency of equipment use and promotes the development of the company. It should be noted that the company should choose appropriate electrical automation equipment according to the actual production requirements, do daily maintenance and maintenance work, use the PLC system reasonably, and fully utilize the necessary functions and values.

(2) Application analysis of PLC control system in the whole process of power switch control

The PLC control system has also been well used in switch control. For most electrical automation equipment, when controlling the switch, the equipment used is a soft relay. Using the PLC control system in this stage can further improve the operation of the equipment and ensure the safety of the equipment. This requires the company to effectively use, according to the actual switch control status of the electrical automation equipment, effectively select the PLC control system, reduce the frequency of use of the switch as much as possible, and realize the unified control function for all isolation switches. Compared with general electrical automation equipment, under the function of PLC control system, the switch control operation is simpler, which improves the reliability of equipment operation.
