Programmer ferri, a 12-year-plus programmer, has developed a team-building career, is good at java, hongmong, embedded, artificial intelligence, and is focused on the things that programmers grow up, hoping to be with you on their way
1. Circuit maps
It's like a map, but it's not to guide you somewhere, but to tell you how the parts of the circuit are connected and working。
1. 1 basic composition
Shape symbols:
The circuit chart contains a variety of symbols, each of which represents a physical electronic component or electrical device, like the icons on the map。
For example, a long line represents batteries, which are positive and short negative
A sign of a sawn or straight and rectangular combination represents electrical resistance, which limits the size of the current
Two parallel wires represent the capacitor and can store the charge
The symbol pointing at a line, like the arrow, is a diode, and the current can only flow in the direction of the arrow。
Connect:
The connection is like a road on a map, which indicates the path by which the current flows between elements. In the circuit map, the currents follow these connections by each element in a sequence from the source of the power, and eventually return to the source or form a closed circuit。
Node:
When several links or the thrusts of several elements are connected together, a node is formed, like a road junction. At the nodes, currents can be allocated or aggregated according to the mode of connection of the circuit。
Annotations
The explanatory notes contain a description of the parameters, function and main function of the circuit as a whole, the design intent, etc. Of the elements in the circuit。
For example, the description of specific parameters such as the size of the resistance, the capacity of the capacitor, the voltage of the power, or the particular function achieved by the circuit, such as the magnification of the circuit, the filter frequency segment of the filter circuit, etc., would help others to better understand the design details and actual use of the circuit methodology。
1. 2 circuit chart function
Indicating circuit structure:
By means of circuit maps, you can see clearly which elements are in the circuits and how they are connected, whether they are linked or more complex. For example, in a simple flashlight circuit, batteries, switches and light bulbs are linked, with currents flowing from the positive pole of the battery, passing through the switch, the light bulb and returning to the negative pole of the battery。
Rationale for analytical work:
Depending on the connection and characteristics of the element in the circuit chart, you can analyse the working principles and functions of the circuit. For example, in an amplifier circuit, the small signal entered can be amplified into a larger output signal through synergy among the components。
Directing electrical installation and maintenance:
When electrical circuits are installed, circuit maps are like construction blueprints that tell you where each element should be installed and how to connect them. And when the circuit fails, you can check the normality of the elements and the connection against the circuit map, so you can quickly locate and neutralize the failure。
1. 3 type of circuit chart
Thesis:
This is the most common circuit map, which shows in detail the symbols of all the elements in the circuit and the connection between them, as if the internal structure of a circuit had been completely exposed. You can learn more about how the circuit works and how the various components work。
Box charts:
The box chart is an electrical chart showing the rationale and composition of the circuit using boxes and links. It divides circuits into functional segments, each of which is presented in one box, with a simple text description in the box, and links between the boxes to each box. The box diagram is relatively concise and suitable for general description and analysis of circuits。
Portrait:
The symbols on the assembly map are often physical drawings of circuit elements, which can be completed by connecting some circuitary elements to the image on the map. Such circuit maps are generally used by beginners or when rapid assembly of circuits is required。
Tablet:
The plates are for the production of drawings for printed circuit boards, which are similar to assembly plans and are used for assembly of actual circuits. On the printed circuit board, the connection between the circuit elements is made through the copper plating, which gives you the position of each element on the circuit board and how it is connected。
All right, everybody, have a good weekend. This is it. Watch me
