Key points and experiences of Integrated Wiring System Construction (1)

With the rapid development of the Integrated Wiring market, many enterprises, communities and families have begun to introduce integrated wiring systems. However, after all, this market is still a market in development, therefore, there are many problems with the construction quality of cabling. I believe that many enterprises and home users are deeply touched by this, for example, an increasing number of household enterprises must spend as much time as possible to meet various business requirements of enterprises, in this case, it is worth pondering what the network cabling system of each room should pay attention to during its implementation.

Before construction

Generally, the network cabling system can be divided into three categories: telephone line cabling, integrated cabling, and Ethernet cabling. They are suitable for different environments, users should have a basic understanding of them before starting the project.

The traditional telephone line cabling system is also called the "household line engineering". Because the system is mainly used to transmit voice signals and narrow band data signals, a pair of copper wires are generally used for long-distance transmission, and the distance can reach 3 ~ 5 kilometers. This wiring can be used to lay a large number of copper cables from the data center in the district to the community. A community can set up several contact points based on the size, and set a distribution box from the access point to the building unit. If a user reports a phone call, the distribution box is directly used for cabling. This wiring project has the characteristics of simple construction, low construction technology requirements, and long-distance transmission.

Smart building wiring is also called Integrated Wiring, A system integration center integrates office automation systems, communication automation systems, and security monitoring automation systems such as power, fire fighting, security, lighting, and air conditioning through integrated cabling systems, achieve the purpose of information management. This wiring project is generally implemented in one or more office buildings, with diversified information points, intensive information points per unit area of 2 information points/10 m²), high transmission bandwidth requirements.

The Community Ethernet cabling adopts a star structure. It is generally implemented in several or dozens of residential buildings through the "Optical Fiber + Five-class cables" mode to provide users with high-speed broadband interfaces. Community Ethernet cabling features five types of lines with a short distance of only 100 meters) and high construction technology requirements. Compared with integrated cabling, the Community Ethernet cabling information is single, with fewer information points per unit area and poor line environments, however, the Ethernet access technology is very mature and standardized. The average port cost is low, the bandwidth is high, and the client device cost is low.

Wiring preparation and procedure

After the network project is investigated and the plan is determined, the next step is the implementation of the project. The first step of the project implementation is the preparation before the project starts: design the actual construction drawing of the integrated wiring, to determine the direction and position of the cabling, consider the following factors: Concealment, damage to the building structure of the building, and avoid power lines and other lines while using the existing space, necessary and effective protection requirements for cables, workload and feasibility of construction, such as bypassing the wall) in the field, etc, the drawings are then provided to the construction personnel, supervisors and supervisors;

Then, we plan the design and budget, determine the routes based on the above conditions, and apply for approval. If you need to bypass the wall on the load-bearing beam, you need to apply to the management department; otherwise, the construction regulations are violated, the overall plan and damage description should be approved by Party A and the management department, followed by the revised plan. Based on the formal planning with the final licensing procedures, the calculation of materials and employment should be carried out, and the budget, construction period, construction scheme and arrangement should be put forward based on the costs of management operations during the design implementation. In the implementation scheme, the degree of cooperation between users must be considered. The implementation scheme should be approved and signed through consultation with the user, and designated coordination personnel should designate the project owner and project supervision personnel, and be responsible for planning materials preparation, preparation, and coordination requirements of the user, propose a timetable for coordination between various departments, coordinate internal and external construction, organize and manage on-site construction site authentication and testing, and prepare a test report to prepare a cabling marking system.

Note that many construction materials are required during the construction of the network project. Some of these materials must be prepared before the start of construction, and others can be prepared during the start of construction, it mainly includes optical cables, twisted pair wires, sockets, information modules, servers, regulated power supplies, hubs, and other manufacturers to purchase goods, and determines the date of delivery, different Specifications of the plastic trough board, PVC fireproof tube, snakeskin tube, self-tapping screws and other wiring materials in place, if the hub is a centralized power supply, prepare wires, iron pipes, and formulate safety measures for electrical appliances and equipment. The power supply lines must be carried out in accordance with the standards and specifications of civil construction. Make proper room for the construction schedule, which is unexpected during the construction process, it may happen at any time and requires immediate coordination ).
