What does weak current contain?
Conceptually, strong electricity and weak electricity are generally easy to distinguish, and the main difference is the different uses. Strong electricity is used as a power source. Weak current is used as a kind of signal electricity. Voltage is not a way to distinguish between strong electricity and weak electricity.
There are two main types of weak current in extended data buildings:
One is low-voltage electric energy such as safe voltage grade and control voltage specified by the state, which is divided into AC and DC. Alternating current below 36V and DC below 24V, such as 24V DC control power supply or emergency lighting standby power supply.
The other is information sources including sound, images and data, such as telephone, television and computer information.
Intelligent system is composed of building equipment automatic control system (BA), safety prevention system (SA), communication network system (CA), office automation system (OA), automatic fire alarm and fire fighting linkage system (FA), which is a comprehensive system integrating centralized monitoring, control and management. All kinds of data collection, control, management, communication control or network system lines in the home are called intelligent lines (that is, weak current in home decoration).
