A must-read for professionals! Intuitive diagrams of weak current subsystems!

The most direct and effective way to get familiar with weak current systems is to look at the pictures!

Want to know the system composition? See the system diagram!

Want to know how the system works? Look at the schematic!

When you first step into the field of weak current, you should first familiarize yourself with the diagrams of weak current electronic systems.

1. Intelligent Engineering

From this diagram, we can see which common subsystems the weak current system is made up of. You don't have to be in the dark when you hear the term weak current system, not knowing what it includes.

2. Schematic diagram of integrated wiring system

This picture is a diagram of an integrated wiring system. As the name suggests, integrated wiring means wiring. As long as the system involves wiring, it can basically be included in the scope of the integrated wiring system.

3. Computer network topology diagram
