Technologycontents目录Practical Operations and Case AnalysisProfessional English Vocabulary and Expression01Introduction to Electrical Engineering and AutomationElectrical Engineering and Automation is a branch of engineering that focuses on the design,development,installation,operation,and maintenance of electrical and electronic systems.Over time,Electrical Engineering and Automation has evolved to include a wide range of sub-fields,including power engineering,control systems,robotics,and more.The profession has its roots in the industrial revolution,where the need for more efficient and automated production processes led to the development of electrical systems.Professional background and development history01Electrical Engineering and Automation professionals are responsible for the design,development,and implementation of electrical and electronic systems in various industries.02They require a combination of technical knowledge,problem-solving skills,and hands-on experience to be effective in their field.03Job opportunities for Electrical Engineering and Automation professionals are projected to remain strong due to the increasing demand for electrical and electronic systems in various industries.Professional characteristics and employment prospectsThe subject system for Electrical Engineering and Automation English courses typically includes core subjects such as electrical engineering theory,automation theory,and English proficiency.Curriculum design should focus on providing students with a solid foundation in electrical engineering and automation concepts while also developing their English language skills.Course materials should be presented in a way that integrates English language learning with practical examples and case studies to enhance student understanding and retention.Subject system and curriculum design02Basic knowledge of electrical engineeringCircuit A closed path that allows current to flow.Series and parallel circuits Series circuits have current flow in the same direction,while parallel circuits have current flow in opposite directions.Voltage and current Voltage is the difference in electrical potential,and current is the rate of flow of charge.Basic concepts of circuits Resistors,capacitors,inductors,diodes,transistors,etc.Circuit components Node voltage method,mesh current method,superposition theorem,etc.Circuit analysis methodsCircuit components and circuit analysis methodsAC(Alternating Current):The flow of electricity in which the direction of current changes periodically.DC(Direct Current):The flow of electricity in which the direction of current remains constant.Advantages and disadvantages of AC and DC electricity.AC and DC electricityMotors Motors convert electrical energy into mechanical energy.They can be AC or DC motors.Transformers Transformers are devices that transform electrical energy from one voltage level to another voltage level.They work on the principle of magnetic induction.Principles of Motors and Transformers03Fundamentals of Automation TechnologyAutomation systems are combinations of control systems,sensors,actuators,and other components designed to automate the operation of machines,processes,and other equipment.They are used in various industries,including manufacturing,process control,transportation,and more,to improve efficiency,reduce costs,and increase productivity.Automation systems can range from simple to complex,depending on the requirements of the application.Overview of Automation SystemsAutomation control principles are based on feedback loops,which monitor the output of a process and adjust its input to maintain desired operating conditions.Modern automation control systems often rely on digital technology,including microcontrollers and programmable logic controllers(PLCs),to process data and control equipment.The control system uses various technologies,such as sensors and actuators,to measure and manipulate physical quantities like temperature,pressure,flow rate,and position.Principles and Technologies of Automation ControlA computer control system is a type of automation system that uses a computer to control machines or processes.It typically consists of a central processing unit(CPU),input/output(I/O)interface,memory,and software programs that provide control algorithms and monitoring capabilities.Computer control systems can be used for a wide range of applications,including industrial manufacturing,process control,aviation,and more.Computer Control SystemAutomation technology has a wide range of application fields.It is used in manufacturing industries to automate production lines and improve manufacturing efficiency.In the transportation industry,automation technology is used in trains,ships,and aircraft to automate navigation,scheduling,and other operations.Additionally,automation technology is used in the energy industry to monitor and control power generation and transmission systems.It is also used in the process control industry to automate chemical reactions,fluid handling,and other processes that require precise control of physical quantities.Application fields of automation technology04Practical Operations and Case Analysis检查实验设备、准备实验材料、了解实验原理和步骤。实验前准备按照实验指导书或教师的指导进行实验操作，注意安全事项。实验操作Experimental operating procedures and
