What types of weak current projects include?

A, building automation system engineering:

Building automation system is widely used in office buildings, hospitals, commercial centers, hotels and other buildings. It is the general name of cold and heat source system, air conditioning and ventilation system, fan tray system, elevator system, water supply and drainage system and other systems. The system mainly manages and controls all kinds of equipment in the building with high efficiency through running state monitoring and fault monitoring, which not only provides a comfortable environment and modern management mode, but also greatly reduces energy consumption and saves costs.

Second, the video surveillance and anti-theft alarm system engineering:

Comprises a monitoring system and an anti-theft alarm system. The monitoring system mainly consists of three parts: front-end monitoring equipment, transmission equipment and back-end control display equipment, among which the back-end equipment can be further divided into central control equipment and sub-control equipment. The equipment of burglar alarm system is generally divided into: front-end detector and alarm controller. The alarm controller is a host computer (like a computer) for processing, including wired/wireless signal processing, fault detection of the system itself, power supply part, signal input, signal output, built-in dialer and so on. The front detector includes door magnetic switch, glass breakage detector, infrared detector, infrared/microwave dual detector and emergency call button. Three, access control management system engineering:

Access control system is a digital access control system, which can control people's access and behavior in buildings and sensitive areas, and accurately record and count management data. Install control equipment, such as access controller, password keyboard, etc. At the entrance and elevator. If residents want to enter, they must have a card or enter the correct password, or a special biometric password to be allowed to pass. Access control management system can effectively manage the opening and closing of doors, ensure the free access of authorized personnel and restrict the entry of unauthorized personnel. Access control management system is an essential part of modern architecture.

Four, parking management system engineering:

Parking management system is a set of network system constructed by computer, network equipment and lane management equipment, which is used to manage the entry and exit of vehicles in the parking lot, guide the traffic flow in the parking lot and collect parking fees. With the increasing number of urban vehicles, the parking lot management system plays an increasingly important role in intelligent buildings, and it is a very important system engineering in weak current engineering.

Five, integrated wiring system engineering:

Integrated wiring system is a set of wiring system specially designed to meet the development needs. For a modern intelligent building, just like the nerve in the body, it adopts a series of high-quality standard materials, integrates voice, data, images and some control signal systems with a unified transmission medium in a modular way, and integrates them into a standard wiring system through unified planning and design, which organically connects the three subsystems of modern buildings, providing a physical medium for the system integration of modern buildings.

Six, communication system engineering:

The communication system integrates all information types such as voice, fax, e-mail, SMS, multimedia data, etc., and can be received by any communication equipment such as telephone, mobile phone, computer, PAD, etc., thus constructing an information interconnection channel among wired, wireless and Internet.

Seven, computer network system engineering:

The computer network system is a system that uses communication equipment and lines to connect multiple computer systems with different geographical locations and independent functions, and uses well-functioning network software to realize resource sharing and information transmission in the network. Through the interconnection of computers, the communication between computers can be realized, so as to realize the function of information, software and equipment resources sharing and cooperative work between computer systems. Its essential feature is to provide a high degree of sharing of various resources between computers and realize the convenient exchange of information and ideas.

Eight, video conference system engineering:

Video conference system refers to the system equipment that two or more individuals or groups in different places transmit sounds, images and files to each other through transmission lines and multimedia equipment, so as to realize instant and interactive communication and achieve the purpose of the conference. Using video conference, you can not only see the people you are talking and communicating with, but also see their expressions and actions, so that people in different places can communicate as if they were in the same room.

Nine, broadcast system engineering:

This system is a new concept multimedia mobile broadcasting service which combines communication and broadcasting, and is called the third generation wireless broadcasting. In addition to supporting traditional audio broadcasting, this technology will also be able to transmit traffic information, news and other multimedia information to mobile phones through MPEG-4H.264, MPEG-2 and AAC+, providing high-quality sound quality and diversified data services. Moreover, it adopts the CDM (code division multiplexing) technology consistent with the mobile phone, which is especially suitable for the mobile receiving environment, and can better cope with the multipath interference problem of signal quality degradation in the mobile receiving environment.

Ten, intelligent residential comprehensive property management system engineering:

Property management system is an indispensable part of modern residential quarters. A good property management system can improve the management level of the community and make the daily management of the community more convenient. It is the development direction of property management to combine the powerful functions of computers with modern management ideas and establish a modern wireless city.

In fact, in practical application, weak current engineering contains many contents. In addition to the systems listed above, there are other systems such as electronic patrol and background music.
