What does weak intelligence mean?

Question 1: What is the weak current intelligence major? Weak current intelligence, if classified in detail, should belong to automatic control. The development of weak current is profound and difficult, such as the integration of computer motherboards. Intelligence refers to the control of weak current, such as PLC single chip microcomputer. The current understanding is nothing more than the centralized control of weak current products. Or other devices are controlled by weak current products. Building intelligence or intelligent building engineering is an application direction of weak current intelligence. For example, computers in factories control the operation of machines. Control and transmission on the network through 485-232 TCP/IP protocol. Weak current is generally not a personal study. Unless you are engaged in product development, you only need to learn signal acquisition and control if you want to operate. PLC single chip microcomputer

This has nothing to do with Jane. The first construction is mainly civil engineering. Roads and bridges. Electrical automation, etc.

Question 2: What does weak current mean? Weak current generally refers to direct current or audio line, video line, network line and telephone line, and the direct current voltage is generally within 24V. Telephone, computer, TV signal input (cable TV line), audio equipment (output line) and other electrical appliances in household appliances are all weak current electrical equipment.

Question 3: What is intelligent weak current engineering? Weak current engineering usually includes integrated wiring system, program-controlled exchange system, network system, TV system, monitoring system, parking lot management system, alarm system, building control system, information release system, patrol system and so on.

Question 4: What is weak intelligence? Intelligent building is an optimized modern new building integrating advanced technologies such as architecture, communication, computer network and monitoring. It has the characteristics of reasonable engineering investment, high degree of equipment automation control, scientific information management, high quality and efficiency service, flexible and convenient use, and safe and comfortable environment, and can meet the needs of the development of information society.

Question 5: What does intelligence mean? Weak electricity is relatively strong electricity. Conceptually, strong electricity and weak electricity are generally easy to distinguish. The main difference is the different uses. Strong electricity is used as power supply and weak electricity is used for information transmission. Specifically, it is roughly as follows:

(1) The AC frequency is different.

The frequency of strong electricity is generally 50Hz, which is called "power frequency", which means the frequency of industrial electricity. The frequency of weak current is often high frequency or ultra-high frequency, which is measured by KHz and MHz.

(2) Different transmission modes

Strong electricity is transmitted through transmission lines, and weak electricity is transmitted through wires or wireless. Radio is transmitted by electromagnetic waves.

(3) Power, voltage and current are different.

Strong electric power is measured in KW (kilowatt) and MW (megawatt), voltage is measured in V (volt) and KV (kilovolt), and current is measured in A (ampere) and kA (kiloampere); Weak current is measured in W (Watt) and mW (Milliwatt), voltage in V (Volt) and mV (Millivolt), and current in mA (mA) and uA (Microampere), so its circuit can be composed of printed circuit or integrated circuit.

Of course, there are also high-frequency (several hundred KHz) and intermediate-frequency devices in high voltage, but the voltage is higher and the current is larger. Another example is flashlights and electric razors. Although the voltage is very low, the power and current are very small, they are still strong. Due to the development of modern technology, weak current has penetrated into high voltage fields, such as power electronic devices and wireless remote control. But these can only be regarded as the weak current control part of high voltage, which is different from charged high voltage.

Question 6: What is the relationship between building intelligence and weak electricity? Intelligent building is the official name.

Weak electricity is a popular name among the people, as opposed to strong electricity.

Question 7: Introduction of weak current intelligent system. According to the national design code "Building Intelligent Design Standard" (GB503 14-2006), it is divided into six systems: intelligent integrated system (IIS), intelligent integrated system, information facility system (ITSI), information technology system and infrastructure. E Information Application System (ITAS) Information Technology Application System Building Equipment Management System (BMS) Building Management System Public Safety System (PSS) Public Safety System Electronic Equipment Factory Computer Room Engineering Each of the above categories contains different subsystems. According to the type and function of the building, the subsystems contained in the intelligent system are different.

Structured integrated wiring system

Strictly speaking, the system is not an intelligent subsystem, but only the physical support of communication network system and computer network system. For the convenience of explanation, this paper also lists it as a subsystem. Some schemes design this system to replace communication network system and computer network system, which I think is inappropriate.

In current high-rise buildings, especially office buildings, wiring system is very important. Generally, it consists of work area, horizontal wiring, vertical wiring, floor equipment room and central computer room. In some projects, there are complex building subsystems between individual buildings. At present, there are more than 5 kinds of common wiring, more than 5 kinds of cables and information sockets, and 6 kinds of cables and modules are used in some projects, showing an upward trend. The vertical trunk line adopts optical fiber, and the incoming line generally adopts 6-core single-mode optical fiber. Ordinary 1000 m to single building, 100 m to floor or desktop.

Closed-circuit television monitoring and anti-theft alarm system

These are two interrelated subsystems belonging to the security system. It is necessary to list the setting list of monitoring points and anti-theft points in this project, and also introduce the manufacturers, brands and functions of the main equipment. At present, hard disk video technology is generally used for monitoring. Some projects need monitoring cameras and lighting linkage.

conference system

The general office building of conference rooms and lecture halls with various sizes and uses needs to be equipped with this system. Because the level and investment required by the construction unit are different, the content of the conference system is also different. There are mainly conference sound reinforcement, projection, camera system, conference video system, conference voting system, speech system and multilingual simultaneous interpretation system.

Large screen display system and touch multimedia information query system

The above two systems are generally set in offices and shopping malls of public construction projects, and the systems are set in public places such as foyer and lobby, which play the role of advertising and guidance to the public. A small control room should be set near the large screen display device with sufficient power supply. Generally, the area of 1 m2 is about 1KW.
