[Textbook Analysis] Electronic Technology Foundation and Skills is a core course of electrical specialty in secondary vocational schools. It takes the completion of electronic process as the main line, integrates the

PLC programmable controller is the mainstream of the development and application of electrical automation. Taking this as an example, this paper connects the adjustable water resistance step-down elements in series with the star-limited starting current of high voltage and large capacity three-phase asynchronous motor to realize smooth starting of motor. This paper also introduces the

Ocean buoy is the most widely used water temperature and meteorological monitoring equipment, which plays an important role in monitoring and harnessing the marine ecological environment. However, because the system needs 24 hours of uninterrupted work, the function problem has become the most critical factor restricting the further development and utilization of the system. Based

With the continuous development of the current economy and the continuous progress of social science and technology, people have accelerated the pace of a series of work on using new tools to replace human resources. Programmable controller is one of the tools. Programmable controllers (PLCs) are developing rapidly from R&D to today’s application and development.

Controller belongs to the brain of industrial robot. The quality of its design has a direct impact on the performance and accuracy of industrial robot. Six-axis industrial robots are one of the types of industrial robots. The complexity of motion control is relatively high. From the point of view of the existing motion controllers in

In recent years, with the continuous development of electrical control technology, the application of PLC is also increasingly widespread. The high performance of PLC controller makes it have strong adaptability and reliability, and it is widely used in the field of automation control. At the same time, because the cost of PLC is low and

With the continuous development of social economy and the continuous updating of science and technology, large-scale numerical control equipment with high technical quality has been widely used in many fields. Therefore, in order to meet the corresponding workpiece processing requirements and ensure the stability of the PID control system, it is necessary to improve the

For the characteristics of simulation training of air navigation radar, a new control version which is close to the real machine and can be used for radar simulation controller is designed, and it can be used for common radar training. The control board is easy to carry and simple to use. This control board combines

In view of the working environment characteristics of the engine electric pump controller, in order to solve the heat dissipation problem and improve the heat dissipation efficiency of the controller in the working process, the FR-4 and LTCC substrates are compared from the aspects of technology, size, material and performance, and the temperature rise simulation

A desktop-level micro-plant factory suitable for laboratory or household is developed by using a low-power and high-performance STM32 microcontroller with ARM as its core.The micro plant plant factory is a concentration of the technology of large plant factory. It can control temperature and humidity accurately, light intensity and light quality ratio and nutrient circulation in
