弱电与强电

弱电和强电不是以电压来区分的通俗点讲弱电是控制或者信号电而强电的做功用的动力电。

Strong electricity conducts electricity, while weak electricity conducts signals. 强电传导电力，而弱电传导信号。 https://min.news/en/home/cb480e910216583ab4dd03fa09977e7c.html

Generally speaking, the processing object of strong electricity is energy (electricity), which is characterized by high voltage, high current, high power, and low frequency. The main considerations are reducing losses, improving efficiency, and weak current. The main processing objects are information, that is, the transmission and control of information. Its characteristics are low voltage, low current, low power, and high frequency. The main consideration is the effect of information transmission, such as the fidelity, speed, and breadth of information transmission. ,reliability. https://www.carefibergroup.com/how-to-distinguish-between-strong-current-and-weak-current

电子电路和电气电路

电力、电子、电气、电器，这次说明白了！从学科划分的角度讲

电力、电子和电器都属于电气工程学科。电气工程一词来源于日本，其中的“气”来源于西方外文翻译（西方工业之初，动力机械均由蒸汽轮机驱动,后来用与发电，故"电气"开始乏指工业动力，现在电气泛指电），电气工程也就是电的工程。

1、电气：电子、电器和电力都属于电气工程，它是一个抽象的概念，不是具体指某个设备或器件、而是指整个系统和电子、电器和电力的范畴。

2、电力：电力是电气工程的强电部分，主要研究电能的提供（即电能的产生——发电系统）、传输（电力线路传输）、变换（高低压变换，变压器、断路器、接触器）；电力分为高压电、电压变配电；

3、电子：电子是指电气工程的弱电部分，主要研究信息的处理、变换；电子又可分为两块：电子电路和电子系统。 - 电子电路（电子元件：制作电路板和电子设计的电子零部件，如二极管、三极管、硅类、LED灯。电子器件：由单个和多个电路板组成的一个电子功能器件）。 - 电子系统：由电子设备组成的系统即——弱电工程系统。

4、电器：电器是具体的设备，狭义上的电器指在工业领域开关。在民用领域，电器是指耗电类电气设备（即用电设备如洗衣机、电视、电冰箱）。

electricity electrical electronics What's the difference between electrical and electronic engineering? Electrical engineering is the design and application of systems, machinery and equipment that use electricity, electronics and electromagnetism. To give you an understanding of what electrical engineers do, they research and develop electrical products and systems for buildings, transport systems and power distribution networks.

A sub-category of electrical engineering, electronic engineering is the design and development of electronic circuits and devices that use components like resistors, capacitors and inductors to perform their function. Electronic engineers design and develop electronic equipment, such as broadcast and communications systems.

Comparing these two types of engineering is like comparing the meaning of electric vs electronic. Electrical devices convert electrical energy into other forms of energy, for example heat, light or sound. Electronic devices control the flow of electrons in order to perform a task. While electrical engineering is concerned with the large-scale production and distribution of electrical power, electronic engineering focuses on smaller electronic circuits.

Studying electrical engineering at university will give you expertise across a range of topics that are central to electrical engineering, and a good command of engineering principles. You will cover electromagnetism, electrical machines and drives, motion control systems, power systems and power electronics.

Electrical and electronics engineering is the branch of engineering concerned with practical applications of electricity in all its forms. Electronics engineering is the branch of electrical engineering which deals with the uses of the electromagnetic spectrum and the application of such electronic devices as integrated circuits and transistors.

机电一体化

机器人系统实际上是一个典型的机电一体化系统，包括机械系统、驱动系统、控制系统和感知系统四大部分。 - 机械系统：机械结构和机构 - 驱动系统：驱动源，电气、气压动、液压或其组合 - 控制系统：（1）硬件（2）软件，人机交互系统和控制算法 - 感知系统（传感）：系统状态传感器

机电一体化：机械设计电气设计控制系统设计：控制器设计、控制信号处理、控制算法开发传感器与执行器软件编程

机械系统：机械结构、运动机构（运动学设计）、执行器和传感器等（传感器和执行器主要涉及安装与布局）；以上关键零部件组成一个个机械子系统。电气控制系统：电气系统、控制器、传感器（信号采集系统、感知）、执行器、通讯系统、能源系统（包括能源管理）等，保护系统（安全保护和故障自检）和调试系统。具有上述多种功能模块，但都可以进行统一划分，包括硬件设计和软件设计。硬件设计时，整个硬件电路中设置不同的模块与相应的机械子系统进行连接，实现信号传输（数据信号和控制信号）。软件设计主要是实现对传感器采集信号，处理和存储，对执行器发射控制信号进行

电气控制系统主要包含硬件设计和软件设计两个方面。 - 硬件设计方面，主要涉及到各种电子元器件的选型、电路设计、PCB设计、电路测试和调试等。这些工作的目标是确保电气控制系统可以正常工作，并满足性能和稳定性要求。其中的典型元器件包括：微处理器、传感器、执行器、电机驱动器、放大器、模数转换器等。 - 软件设计方面，主要包括编程和调试工作，目的是编写控制程序，实现机器人的各种功能和任务。软件设计工作一般使用高级编程语言进行编写，如C++、Python等。软件设计还需要对控制器进行编程、测试、调试和优化，以确保机器人系统的高效、稳定和安全运行。软件设计也包括对控制器的固件进行更新和升级。实际应用中，从底层开始硬件设计是比较复杂的，因此通常进行成熟元器件模块的应用集成，属于硬件集成或硬件系统设计。而真正具有挑战性的是软件设计方面的工作，除了进行基本任务要求的编程实现外，还需要对控制算法的编程实现。
