This paper introduces a variable frequency constant pressure water supply system with AI intelligent controller and frequency converter as its core. The system consists of four parts: pressure sensor of water supply pipeline, centrifugal pump, frequency converter and AI intelligent controller. By detecting the water supply pressure of the pipeline, the AI intelligent controller drives

Aiming at the problems of non-linearity, large lag and time-varying of water temperature change in aquatic greenhouse caused by large specific heat capacity of water body, thermostatic element considering the disadvantages of poor adaptive ability and weak robustness of traditional PID controller, a PID control strategy based on BP neural network is proposed. In this

In this paper, the characteristics of Si4010 and Si4463 RF chips developed by Silicon Laboratories and the design of remote control system for garage door controller are introduced. Provide reference for product development and other wireless application design in related industries. With the development of society, people’s living standard is constantly improving, and the purchase

This paper describes the design and implementation of a customized controller which can control AC servers instead of PC in some specific occasions. The controller uses only one CPLD as the main control chip, does not need MCU and external memory, and has simple peripheral circuit design. The parameters are configured and stored using FLASH

Automation, informationization and mutual you, you */ dynamic smart grids need a smarter network. SDN Software Definition Network (SDN Software Definition Network) can help the rapid development of intelligent power/network. OpenDaylight is an open source controller framework for SDN. It is easier to open and innovate SDN in a collaborative way and model driven architecture.

Aiming at the problem that the processing ability of software-defined network single controller can’t meet the requirement of scalability and that the current distributed multi-controller platform can’t change the service according to the actual situation, this paper puts forward the design of service abstraction layer at the control level, and tests the feasibility of the
