Weak current integrated wiring construction
1. Information release system of weak current integrated wiring system
The information distribution system is generally dominated by LED display screens, and the construction and installation requirements of LED display screens are relatively high. In particular, the networking mode of LED display screens of information distribution systems is relatively complicated. At present, there are two types of networking methods: the first one, LED The display screen is networked through the pre-reserved integrated wiring points; the second, the LED display screen is networked through the integrated wiring points. However, no matter what kind of networking method is used, there are technical requirements for the construction of the information release system. Therefore, it is necessary to adopt inter-professional technology and means to do a good job in the installation of the LED display of the information release system.
2. Computer network system of weak current integrated wiring system
In order to adapt to the development of computer application level, the construction of computer network system must meet the needs of users for various information services such as information management and information inquiry. The computer network system can be directly connected to the switch traffic through the core switch, effectively reducing the number of failure points, giving full play to the powerful forwarding capability of high-performance routing switches, greatly increasing the reliability of the entire local area network, and having excellent performance and price. Compare.
3. Safety protection system of weak current integrated wiring system
The safety protection system is an extremely important part of the weak current integrated wiring system. The construction of the security prevention system will provide a variety of security technology prevention means for the entire system, forming a multi-mode, multi-technology, hierarchical three-dimensional security technology prevention network, which not only realizes early warning and alarm (intrusion alarm, TV monitoring, etc.) , and realize the functions of deterrence, complete prevention and on-site evidence collection when illegal activities are carried out. The safety protection system can create a safe and efficient working environment for users through the organic combination of technical defense and human defense.
The security protection system is divided into surrounding security areas, public security areas, key security areas, etc. from the space area. The system uses digital multimedia technology, computer image processing technology, and digital video recording and storage technology to achieve main public places and important parts. 24-hour real-time monitoring, video recording and alarming. To ensure the advanced nature of the security protection system, it is necessary to use mature information technology, control technology and management decision-making means to build an intelligent security protection system with high standards and complete functions. The comprehensive security protection system consists of a multi-level, three-dimensional, It is built with a high degree of integration of on-site images and various alarm, entrance and exit information systems, and finally creates and creates a "safe, convenient, flexible and comfortable" office environment for the owner.
The security protection system includes three subsystems including video surveillance subsystem, anti-theft alarm subsystem and patrol subsystem. Based on the entire area, a set of integrated security management system and intrusion alarm system, video surveillance system, perimeter defense system is created. , wireless patrol and other subsystems composed of a comprehensive security system. The monitoring center equipment is networked with each subsystem equipment through a unified communication platform and management software, so as to realize the automatic management and monitoring of each subsystem by the monitoring center. The whole system has a communication interface connected to the alarm center, multiple data input/output interfaces, and can be connected to the upper management computer to realize management and communication automation.
4. Cable TV system of weak current integrated wiring system
The cable TV system can be set up with a host room, which is conducive to the construction of the entire cable TV system in accordance with the digital TV system framework. The cable TV system is realized by assigning a branch, the image definition meets the level 4 or above, and the user terminal level meets 64±4dB. The signal satisfies 5～860Ⅲz. The hybrid optical fiber and coaxial cable (HFC) bidirectional system is used to transmit the amplified terrestrial cable TV signal to the user terminal in a branch-distribution mode.

The construction of the weak current integrated wiring system is a prerequisite for the realization of intelligentization of modern buildings. It can effectively manage various electronic equipment and office systems in modern buildings, and is the material guarantee for building an Internet of Things society and an information society. In addition to considering the rationality and application requirements of power grid planning, the following three points should be paid attention to when constructing a weak current integrated wiring system:
1. Normative construction of weak current integrated wiring
The weak current integrated wiring system should pay attention to the technical specifications during the construction process. Since the integrated wiring system basically adopts the modular design and layout, all installation and construction plans must strictly follow the above-mentioned specifications and standards. At the same time, according to the confirmation in the contract According to the construction specifications, the layout of the integrated wiring system is realistic and the scientific and reliable construction is guaranteed.
