In the decades after the third scientific and technological revolution, the world economy has developed rapidly under the leadership of scientific and technological forces, and many industries have seen the opportunity of the rise. The electrical engineering industry has developed rapidly in this context and gradually in the world. The economic structure occupies an important position. Electrical equipment, whether it is large mechanical equipment or small electrical equipment, is inseparable from the control system.
In the traditional electrical engineering industry, most of the mechanical control components are used to control the opening, running, shifting and closing of the equipment. The mechanical control components can only rely on manual manual contact control. Some of the equipments are bulky and cumbersome, relying on manual manual control. Complex and labor intensive, and the control of some devices is dangerous. The modern technology makes the electrical engineering industry continue to develop towards automation and intelligence. As the representative of the intelligent intelligent remote control technology, motor control plays an important role in modern electrical engineering with its characteristics of safety, convenience and high efficiency. effect.
Overview of motor control
Due to the wide variety of electrical equipment, different specifications and functions, and the application fields are also very extensive, the control of the motor can not be simply summarized. The electrical equipment for different types, uses, fields and operation modes must be designed accordingly. The motor control system, however, no matter how the control system is designed, the technical concept of motor control and automation is always compatible. Automation is the main technical core in motor control. The concept of automation is continuously recognized and deepened, which directly affects the control mode of motor control. Affected by the development and influence of computer technology, the core of motor control technology has begun to transform into the field of computer remote control, and has realized the development of intelligence and has been recognized in the industrial field.
1.1 Before adding the computer remote control system, the motor control is mainly controlled by the alternating current control. With the integration of the computer remote control technology, the motor control mode has undergone new changes, and the remote communication technology has become the new dominant in the motor control mode. Remote communication is actually the use of unilateral communication technology between computers and microcontrollers. The control platform takes the computer as the host and remotely controls the motor control device through remote communication with the single chip microcomputer, thereby realizing the motor control mode based on computer communication technology. The remote communication technology has completely changed the control mode of the electrical equipment. Through the control of the computer, not only the remote control of the equipment can be realized, but also the operation of the equipment can be effectively monitored, and the sudden problems can be quickly processed to avoid the space. Restrictions result in untimely processing and safety hazards that can be caused by labor. At the same time, motor control of one person to multiple devices can be realized, saving human resources.
1.2 Embedded technology is also an important technical means in the modern application of motor control. Its application, on the one hand, guarantees the smooth communication of remote communication, on the other hand, because of the compact size advantage of the embedded system, it not only saves the system space of electrical equipment, but also facilitates the implementation and development of remote control operations, and can also The operation of electrical equipment provides greater security.
1.3 Automation As the core of motor control, modern motor control systems are inseparable from the support of electrical automation systems. The electrical automation technology is integrated into the motor control. Through the electrical automation system, the issuance and reception of commands are processed by the control center to complete the operation process of the entire system. The motor control equipment should be designed in consideration of the key elements such as the working environment and working mode of the electrical equipment used in the motor equipment, and designed in a targeted manner so that the motor control equipment can fully meet the functional requirements of the electrical equipment. 2 Common operational skills of motor control In modern industrial production, the application of motor control equipment is the most common. Although the integration of automatic remote control technology makes electrical control more convenient and convenient, the demand for motor control equipment in industrial production is extremely complicated. Therefore, there are high requirements for the technical aspects of the staff. Let us briefly introduce the common techniques of motor control.
