The structure, timing and related concepts of SDRAM are introduced. On this basis, based on the top-down design idea, the controller module is divided into two parts: internal command generation and command output. Based on verilog, the two modules are implemented and the top-level entity is completed. Tests show that the controller is effective. SDRAM

In pneumatic conveying system, the dome valve is the main equipment. Usually, because of the physical separation of pneumatic part and electronic part of the control box and insufficient collection of valve status signals, the open-loop control of the dome valve reduces its service life and makes it difficult to deal with faults. After using

With the improvement of people’s living standards and the increasing awareness of energy conservation, people are demanding more and more energy-saving and environmental-friendly products. Accordingly, people have more and more strict requirements on the performance of solar water heater products in their daily life. At present, there is still some backwardness in the control system

The traditional design method of route coordination controller has some problems, such as less data transmission times and inaccurate transmission, which can not balance the distribution of nodes and greatly reduce the efficiency of network control. Therefore, the design of communication network routing coordination controller based on cloud computing environment is proposed. The block diagram

PID controller plays a key role in the performance of HVAC control system. HVAC control system is non-stationary and time-varying, which makes the traditional PID controller unable to achieve high-precision HVAC control effect. In order to overcome the shortcomings of traditional control methods and improve the accuracy of HVAC control, a HVAC control system based

In this paper, the basic principle of the accuracy of the microcontroller digital converter (ADC) is studied, and the feasibility of the STM32 microcontroller core is analyzed. At the same time, whether the over-sampling technology can be tested by STM32 microcontroller technology through the research data, it is concluded that the use of over-sampling technology

The IGBT module, DC-DC module, motor control module, vehicle controller and key electrical parts of the electric vehicle power control system are all integrated in the same shell by adopting integrated design scheme. IGBT module and DC/DC module are the heating parts of power control system. The steady and transient analysis of IGBT module and

Electric control valve is the product of the development of industrial automation. Its actuator has been widely used in industrial pipelines and fluid control and other industrial occasions. With the development of industrial automation in China, the market has strict requirements on the response speed and accuracy of valve opening and closing procedures. Strengthening the

In this paper, thermostatic element a new ATE microwave controller is designed and developed to automate the control and connection of various ATE RF circuits. According to the overall design scheme of ATE microwave controller and the actual requirements of radio frequency control of ATE microwave controller, the overall architecture, hardware structure and conditioning circuit

“Principles and Applications of Microcontrollers” is a practical and applied course, but in the process of teaching, due to the simplicity of traditional teaching mode and the emphasis on theoretical teaching, this course lacks the necessary practical learning. Through the reform of classroom teaching methods and experimental teaching system, this paper stimulates students’interest in learning
