Key Points of Integrated Wiring System Design (1)

There are many notable points in the design of the Integrated Wiring System. Here we mainly introduce the overall planning and design requirements of the Integrated Wiring System, including the introduction of performance and specifications, I believe you will learn a lot after reading this article.

1. Overall Planning

In general, international information and communication standards are gradually revised and improved with the development of science and technology. The Integrated Wiring System is gradually mature with the development of new technologies and the advent of new products. It is necessary for us to propose and study recent and long-term requirements during the design of intelligent building PDS. At present, all the integrated wiring products in the world only propose a 15-year quality assurance system, and do not propose annual investment assurance. In order to protect the interests of building investors, we can adopt "overall planning, distribution implementation, and horizontal cabling in one step as far as possible ". Most trunk lines are deployed in Weak Current wells of buildings. It is easier to replace or expand them. horizontal wiring is deployed in the ceilings or pipelines of buildings. The construction fee is higher than the initial material cost. If horizontal wiring is changed, the structure of the building should be damaged, affecting the overall appearance. Therefore, we are designing horizontal cabling and try to use cables and connectors of higher grades to shorten the cabling cycle.

2. System Design

Integrated Wiring is an emerging technical project in the Construction of smart buildings. It is not entirely a "weak current" project in construction projects.

Intelligent Building is composed of the system integration center in the intelligent building environment to connect and control the "3A" system using the Integrated Wiring System. Whether the wiring system is properly designed directly affects the "3A" function. (3A is Building Automation-Building Automation, Office Automation-Office Automation, Communication Automation-Communication Automation) There are generally six steps to design and implement a reasonable Integrated Wiring System:

Obtain the floor plan of a building;
Analyze user requirements;
System structure design;
Wiring and routing design;
Draw the wiring construction drawing;
Prepare a wiring materials list.

The star-type topology is used for cabling. It has a wide range of functions and allows any sub-system to be cabled separately. Each sub-system is an independent unit group. When any sub-system is changed, other sub-systems will not be affected.

The goal of a well-designed cabling system is to allow horizontal cabling without compromising architectural decoration during the integration process with new requirements beyond the established time.

In order to make the Engineering Design of the Intelligent Building and Intelligent Building Park concrete, according to actual needs, we divide the Integrated Wiring System into three levels:

1. Basic Type

It is suitable for the scenario where the configuration standards are low in the Integrated Wiring System. It is made of copper core cables.

Basic Integrated Wiring System Configuration:

(1) Each work area (Station) has an information outlet;
(2) Each work area (Station) uses a 4 pair twisted pair cable and leads it to the floor distribution frame;
(3) hardware is handed over by means of a folder;
(4) Each work area (Station) has at least two pairs of twisted pair wires for the trunk cable (that is, the floor distribution frame to the total distribution frame wire between equipment.

2. Enhanced

It is suitable for medium configuration difficulties in integrated wiring systems, and is connected to copper core cables.

Configuration of the enhanced comprehensive distribution system:

(1) Each work area (Station) has more than two information outlets;
(2) The wiring cables of each work area (Station) are independent 4 pairs of twisted pair wires, leading to the floor distribution frame;
(3) hardware is handed over by means of a clamp (110A series) or a connector (110P series;
(4) Each work area (Station) has at least three pairs of twisted pair cables (that is, the floor distribution frame to the total distribution frame of the device.

3. Comprehensive

It is applicable to scenarios with high standards in the Integrated Wiring System. It can be connected through a hybrid network of optical cables and copper core cables.

Integrated Wiring System Configuration:

(1) adds an Optical Cable System Based on the basic and enhanced cabling systems;
(2) At least two pairs of twisted pair wires are attached to the trunk cable in each basic work area;
(3) there are at least three pairs of twisted pair wires in the trunk cable of each reinforced work area.

The Integrated Wiring System should be able to meet the transmission rate requirements of the supported data system, and the corresponding levels of transmission cables and equipment should be selected. The Integrated Wiring System should meet the supported speech, data, and image system transmission standard requirements.

All devices in the Integrated Wiring System must be connected to terminals, cables insulated from plastic, or cable rings. Not only do each line pair use color recognition, but only the harness group uses the color labels in the same chart. This is conducive to maintenance and repair. This is also one of the characteristics of the Integrated Wiring System.

All basic, enhanced, and integrated cabling systems support voice, data, images, and other systems, and can be switched to a more functional cabling system as needed by the project. The main difference between them is:

① Support for voice and data services;
② Implement line management flexibility when moving and re-deploying.
