microsystem refers to preschool children

microThe system refers to the environment that has the most direct impact on children. The middle system refers to the process of connecting individuals and their microsystems. The external system refers to the fields that children cannot cover, but will also have an impact on children. The macro system envelops the above three systems, which is a cultural system covering the macro level of society.

Microsystem: This is the place where children live and their surrounding environment, such as families, kindergartens, schools, neighbors and communities.

Microsystem: including children, families, schools, peers, childcare centers and community neighborhoods, etc., which is the environment in which children have direct contact. Mesosystem: It is related to the relationship network between family and children, such as the connection between family and school.

The concept of microsystem

1. The innermost layer of the environmental hierarchy is the microsystem, which refers to the direct environment of individual activities and interaction. This environment is constantly changing and developing, and is the innermost layer of the environmental system. . For most babies, microsystems are limited to families.

2. Microsystem refers to the direct environment of individual activities and interaction, which is the first layer of the ecosystem structure. The intermediate system refers to the connection or mutual relationship between various microsystems. It is the second layer of the ecosystem structure.

3. Micro PE refers to the micro Windows PE system, which is the abbreviation of Windows Preinstallation Environment.This is an ultra-lightweight Windows system that can run on removable storage media such as CDs and USB flash drives, which is mainly used for rescue, maintenance, backup and recovery.

4. x0dx0a microcomputer system: refers to a complete computer system composed of hardware and software. That is, hardware is a microcomputer and a whole with a software system.

5. A complete microcomputer system consists of two parts: hardware system and software system. Folding Hardware Part Central Processing Unit (CPU) is made on an integrated circuit chip, also known as Micro Processor Unit (MPU).

6. The microprocessor is the core hardware, and the volume is the smallest of the three, and it is indeed the most important of the three. The hardware of microcomputers, including microprocessors, is the most basic hardware system, commonly known as bare metal, and a unified platform to support software operation.

The interrelationship between microsystems and microelectronic technology

1. The internal structure of microelectromechanical systems is generally microns or even nanometers, which is an independent intelligent system.

2. Micro-Electro-MechanicalSystem (MEMS) is called micro-electro-mechanical system, micro-system, micro-mechanical, etc., which refers to high-tech devices with a size of several millimeters or even smaller.Micro-electromechanical system (MEMS) refers to a micro-mechanical equipment and mechatronics system based on microprocessing systems.

3. Micro-Electro-Mechanical System (MEMS, also known as Micro-Electro-Mechanical System, Micro-System, Micro-Mechanical, etc., is developed on the basis of microelectronic technology (semiconductor manufacturing technology).

4. Transistors and integrated circuits are "all the results of the development of microelectronic technology. Compared with traditional electronic technology, microelectronic technology is based on the miniaturization of electronic equipment and systems. This is an emerging technical discipline since the 1960s. It has both exquisite theory and attractive practical prospects, which is extremely challenging to study.

5. Compared with traditional electronic technology, the main feature of microelectronic technology is the miniaturization of devices and circuits.It closely combines the design and manufacturing process of the circuit system, which is suitable for large-scale mass production, so it has low cost and high reliability.

6. The meaning of microelectronics Microelectronics technology is a new technology developed with integrated circuits, especially ultra-large-scale integrated circuits.

micro-measurementWhat are the micro-energy microsystem controls?

Micro-energy: mainly involves micro-nuclear energy, solar cells, micro-fuel cells and micro-thermal energy, etc. Microsystem control: mainly involves micro-robots, micro-operation, micro-assembly, etc.

The control functions of microgrid mainly include active power and reactive power control (P-Q control), voltage regulation based on differential adjustment, rapid load tracking and energy storage, and frequency differential adjustment control. The proposal of microgrid aims to realize the flexible and efficient application of distributed power supply and solve the problem of large number and diverse forms of distributed power grid connection.

For this control mode, the strategic choice of the distributed power controller is very important. One of the commonly used methods is Droop control. The hierarchical control mode is generally equipped with a central controller to send control information to the distributed power supply in the micronet.

CPU (central processor): The microcontroller contains a small central processor for executing control programs. This CPU is usually an 8-bit, 16-bit or 32-bit architecture, depending on the microcontroller model. Memory: Microcontrollers usually include flash memory (Flash) and random memory (RAM).
