Question 6: What does the weak current system include? There are two main types of weak electricity. One is low-voltage electric energy such as safety voltage level and control voltage stipulated by the country. It is divided into AC and DC, AC below 36V and DC below 24V, such as 24V DC control power supply or emergency lighting backup power supply. . The other type is information sources carrying voice, image, data and other information, such as telephone, television, and computer information. People are accustomed to refer to weak current technology as weak current technology. It can be seen that the basic meaning of weak current technology in smart buildings is still weak current technology in the original sense. However, with the rapid development of modern weak current high and new technologies, the application of weak current technology in smart buildings is becoming more and more widespread. Such as intelligent fire protection systems, monitoring systems, computer networks, building automation, intelligent broadcasting, etc. The degree of application of weak current technology determines the degree of intelligence of smart buildings. Weak current system engineering refers to the second type of application. Mainly include: 1. TV signal engineering, such as TV monitoring system and cable TV. 2. Communication engineering, such as telephone. 3. Intelligent fire protection engineering. 4. Sound amplification and audio engineering, such as background music broadcasting in communities and background music in buildings.

5. Integrated wiring engineering, mainly used for computer networks. With the rapid development of computer technology, the rapid and powerful functions of software and hardware, and the perfect combination of various weak current system engineering and computer technology, the various classifications in the past are no longer as clear as before. The mutual integration of various projects is system integration.

Question 7: What are the contents of weak current in indoor decoration? What are the weak current materials in home decoration:

1. Telephone line

The telephone line is for For telephones, it is composed of copper core wires. The number of cores can determine the number of phone extensions that can be connected. Common specifications include two cores and four cores. In home decoration, a two-core telephone line is generally sufficient, but if you also need to connect a fax machine or a computer to dial-up Internet access, it is best to use a four-core telephone line. Telephone lines can be replaced by network cables, and now some home phones are connected through network cables.

2. TV cables

There are currently two main types of cables used to transmit TV signals: cable TV coaxial cables and digital TV coaxial cables. The cable TV coaxial cables are double-shielded. , there will be a certain loss when used to transmit digital TV signals; digital TV cables use four-shielded cables, which can transmit both digital TV signals and cable TV signals. In terms of anti-interference, four-shielded cables are better than double-shielded cables. You can use a utility knife to break them apart to compare.

3. Network cables

There are three main types of network cables: twisted pair, coaxial cable, and optical cable. It is a data transmission line composed of many pairs of wires. Its characteristic is that it is cheap, so it is widely used, such as our common telephone lines. It is used to connect to the RJ45 crystal head. It has two types: STP and UTP. The one we commonly use is UTP.

4. Audio-visual cables

Lines used to transmit music and videos, mainly including audio cables, audio cables and audio-visual cables. Audio cables, commonly known as speaker cables, are mainly used to connect the power amplifiers and speakers in the home theater in the living room; audio cables are used to carry the output signals of laser CD players, DVDs, etc. in the home theater in the living room to The connection of the signal input terminal of the background music power amplifier; the audio and video cable is mainly used for home audio-visual system applications.

Question 8: What is a weak current system? What does a weak current system include? Electric power applications can be divided into strong current and weak current according to the strength of the power transmission power. The electricity used in buildings and building complexes generally refers to strong electricity of AC 220V50Hz and above. It mainly provides electric energy to people and converts electric energy into other energy sources, such as air-conditioning electricity, lighting electricity, power electricity, etc. There are two main types of weak electricity in smart buildings. One is low-voltage electric energy such as safety voltage level and control voltage stipulated by the country. It is divided into AC and DC, AC below 36V and DC below 24V, such as 24V DC control power supply, or emergency power supply. Backup power supply for lights. The other type is information sources carrying voice, image, data and other information, such as telephone, television, and computer information. People are accustomed to refer to weak current technology as weak current technology. It can be seen that the basic meaning of weak current technology in smart buildings is still weak current technology in the original sense. However, with the rapid development of modern weak current high and new technologies, the application of weak current technology in smart buildings is becoming more and more widespread. Such as intelligent fire protection systems, monitoring systems, computer networks, building automation, intelligent broadcasting, etc. The degree of application of weak current technology determines the degree of intelligence of smart buildings.
