Micro-logic controller not only can be programmed and controlled, but also covers some functions of traditional relay. From the application level, Micro-Logic controller fills the gap between traditional relay and PLC. Taking the electric control of electric hoist as an example, this paper introduces the simplicity and intelligence of microcontroller in comparison with traditional relay

This paper presents a constant temperature and humidity controller based on Internet of Things cloud service platform. 　　The hardware design of the controller is introduced in detail from the aspects of processor, Ethernet module, temperature and humidity sensor and I2C interface, relay module and current output module. The actual results show that the controller has

Due to the design flaws, the controller of distribution automation demarcation switch is often operated or adjusted by non-distribution secondary operators in operation, resulting in widening the scope of power failure and accident. Therefore, Zibo Power Supply Company developed a locking device for user demarcation switch, and achieved good results in application. With the development

In the grinding process, a large number of PID controllers are needed. In this paper, the improved algorithm of global optimization is studied in depth, and combined with the PID controller, the global optimization PID controller is formed. The simulation results of MATLAB show that the intelligent PID controller has good effect and strong stability.

This paper briefly introduces the working principle of the support controller, makes a thorough research and Analysis on the design of the automatic detection device of the support controller, and combined with this research, puts forward some suggestions and opinions, hoping to help the research of the automatic detection device of the hydraulic support controller

In order to cooperate with the project-based teaching of Programmable Controller Application Technology, the project-based teaching material is developed according to the principle of “project guidance and task-driven”. The idea and practice process of the development of the teaching material are introduced. The modular structure of the teaching material “project, task”, as well as “task

The so-called bidirectional DC-DC converter is a kind of converter which can transfer energy bidirectionally while maintaining the polarity of DC voltage unchanged. Due to the similar characteristics of bi-directional DC-DC converter in boost and buck mode, the dynamic model of bi-directional DC-DC converter in boost mode is established and the corresponding controller is designed.

Wind-solar complementary generation has been widely used in distributed generation systems in recent years. Aiming at the shortcomings of wind-solar complementary power generation system, such as low power generation efficiency and high system cost, a system controller is designed and developed. Based on modular design, the controller can flexibly adjust the capacity of power generation

With the continuous improvement of automation and mechanization in our country, industrial robots have been widely used in the field of mechanical manufacturing, and industrial robot controllers are becoming more and more standardized, and their openness has gradually increased. Soft PLC system is one of the most important components of industrial robots, which conforms to

With the rapid development of China’s equipment manufacturing industry, the valve controller controlled by the combination of traditional mechanical devices and simple analog electronic technology can not meet the requirements of industrial automation. In order to improve the intelligent degree of valve controller, it is necessary to study an intelligent electric valve controller. The controller
