0. Introduction

    With the promotion of network communication technology, control and transmission technology, the application technologies such as microcomputers and integrated circuits have been expanded, providing conditions for the deep integration of electronic and mechanical technologies and promoting the rapid development of motor control and protection systems.

1.  Apply advanced technology

As a basic function in the system, motor control and protection should be optimized and strengthened from the perspective of design, and the application of advanced technology should be used to improve the overall control and protection quality. In the application environment of mechatronics, although motor protection and control are basic internal functions, the reliability and stability of this function affect the application results of mechatronics. In addition to its own importance, the protection and control function also involves the effective realization and stable operation of other functions. Therefore, in the process of strengthening motor control and protection, the application of advanced technology can improve the quality of motor protection and control through the optimization design and update of the device. From the perspective of current technological development and technological update, in the design optimization process of mechatronic motor protection and control devices, the overall level of mechatronics can be improved by adding optoelectronic technology. In the traditional technology application process, motor control and protection mainly adopt bus control technology, which has high safety and reliability, but there are certain design defects. In the process of strengthening motor control and protection, information technology can improve the quality of motor control and protection by combining with traditional bus control technology. At the same time, information technology can also realize the coordinated linkage and joint control of motors and other equipment through automated control and convenient information exchange, and further ensure the reliability of motor control and protection on the basis of effective tracking.

2.   Improve the level of modularity

In the context of the development of mechatronics technology, with the continuous updating and evolution of the times, in the process of continuous development of technology, there are also scenarios of technology replacement and technology change in the application environment. Therefore, the development of technology should take into account the needs of technology update and the overall application environment. As a dynamic update and change process, technology development should be aware of the maturity of current technology and the continuity of technology update in its development process. In the context of the development of mechatronics, the motor protection and control equipment currently used has improved quality and reliability. At the same time, the motor control and protection devices used in my country's industrial systems still have certain defects and deficiencies. In order to promote the compatibility of equipment and the standardization of the industry, in the current mechatronics construction process, the modularization level can be improved to limit the direction of motor protection and control equipment design and development from the perspective of the industry, and the motor protection control risks caused by compatibility issues can be avoided through modular and standardized production methods.

3.   Intelligent level

In the face of the current practical problem of poor integration of motor control and device system equipment, in order to solve the problem of increased costs caused by equipment differences in motor control protection devices, the current motor control protection must be realized through the continuous improvement of intelligence and digitalization levels, and the design and optimization of equipment integration to achieve linkage control between devices, which not only saves the cost of motor equipment and control, but also improves work efficiency by increasing the integration speed. In addition to the updating and development of technology, in the context of equipment integration, the application of digital and intelligent technology can realize fault warning and preventive maintenance. Traditional motor control protection devices have high maintenance costs, while digital and intelligent technologies can timely clarify the current working status of the equipment through convenient network transmission and automated detection, analyze the abnormal situation of the equipment by comparing the current data with the standard data, and timely discover problems, which also promotes the improvement of equipment maintenance efficiency.

4. Development ideas and prospects of motor control and protection technology

First, consider future maintenance work at the beginning of the design, make plans in advance, and make overall planning. Second, expand the thinking of equipment maintenance problems, innovate protection devices, and make development ideas more diverse. Third, change management, observation, methods, and methods. During the operation of the equipment, according to the actual situation, everything is aimed at better and faster, and the problems that arise are solved in time. Therefore, the digital supervision model is the main direction of current development because of its high speed and comprehensiveness.

The current situation of motor control protection is the lack of innovative ideas and technological innovation. In recent years, some new theoretical methods have been proposed to address these problems. It is expected that through simulation calculation and fault modeling, data analysis will be conducted by introducing various detection quantities that are sensitive to motor faults, such as breakthrough quantity, phase quantity, harmonic component, impedance quantity, sequence quantity, etc., and corresponding judgments and analyses will be made. These workloads will be completed in advance to improve the accuracy and sensitivity of the protection and control device, and provide a basis for future theoretical research and future breakthroughs. The application and development of new technologies is also an important aspect of motor control and protection devices. The operation of the motor is monitored in real time using new technical products and theories, and then judged by computers based on the information output by various devices, the reflected data is classified, the fault type and severity are determined through scientific analysis and comparison, and finally corresponding remedial measures are taken. This will not only realize the above various motor protection and control functions, but more importantly, it can issue early warnings before the fault occurs, so as to prevent the fault from happening in advance and prevent it before it happens.

An important development prospect of motor control and protection devices is to actively match the factory motor protection control devices, find out the deficiencies and defects according to the international quality standard level, and design and plan according to the actual situation in my country, and strive to adapt to China's national conditions. After the motor is produced, some foreign countries will give or add supporting auxiliary facilities in the marketing stage. In the short term, it may cause low efficiency and other phenomena, but in the long run, it will make the buyers get real benefits, ensure the efficiency and quality of mechanical operation, improve the service life of the machinery, and reduce resource waste. We should actively develop supporting operation mechanisms to improve the purchasing efficiency and use efficiency, avoid the damage of the machine caused by improper use and configuration, low durability, and high cost. On the one hand, it will improve the reputation of the producer and lay the foundation for further promotion of the product throughout the country and even the world. Therefore, the matching of motors and their control and protection equipment can not only promote the use effect of each other, broaden the long-term development of the motor industry, but also promote the scientific, humanized and globalization of the entire electromechanical industry.

5 Conclusion

With the development of computer network technology and electronic power technology, the functions of motor control and protection systems are becoming more and more perfect, reducing the incidence of motor control and protection failures, taking effective measures to eliminate related failures, and ensuring the stable and safe operation of motor control and protection systems, thereby effectively promoting the continuous safety and healthy development of motor and control protection systems.
