Problems involved in the design of integrated wiring system

As the saying goes: "Trinidad, a single one," for a good integrated wiring system design configuration and scheme, fully understand the user needs and applications is the basis of integrated wiring system design. If the customer needs and applications are not fully understood, the design will be meaningless. Designers can fully understand users ' needs and applications through on-site investigation, reading bidding documents, technical exchanges and answering questions. The following is mainly introduced in the integrated wiring design, need to take into account or involved in some of the problems,

The physical link design of wiring system

1, determine the host room or the main wiring between the location

Generally in the Design institute or consulting companies and users have designated the location of the wiring room, cabling the computer room most of the network room with the common use, there are some separate settings, or data room and voice room may also be separate. In this case, need to check whether the machine room can meet the wiring system requirements. If the user has not clear the room location, you need to be based on the actual situation and the basic requirements of the computer room to determine the location of the room, and communication with users, access to user recognition.

2. Determine the position between the weak shaft and the distribution line

General in the Design institute or consulting companies and users have designated the weak shaft and distribution between the physical location of the line. In this case, you need to see whether the distribution lines can meet the requirements of wiring design standards, such as GB50311 "Integrated wiring system Engineering design code." If the user has not clearly assigned to the location of the line, it needs to be based on the actual situation of the site and the basic requirements of the room to determine the location of the room, and communication and coordination with users to obtain the user's approval. The position and quantity between the shaft and the distribution line will directly affect the project cost, if you find that the original design is unreasonable (this happens often), you can also directly communicate with the user, consulting company or Design Institute, request to make changes, of course, need to do the design change document work, in order to file in the future completion of the document.

3, point table statistics

A list of materials can be produced only after a table of good points has been identified, so the point table is a prerequisite for the BOM list. General cabling Project Engineering, often point bitmap in the inventory configuration, design institute or consulting company has given the floor plan, which will have a more detailed point bitmap, and then detailed statistics data points, voice points, fiber to the number of desktop points and distribution, and then made into detailed dot statistics, Of course, some of the integrated wiring project may include a point bitmap, and what drawings are not, it needs to be in accordance with the GB50312 "Integrated wiring system Engineering Design Code" in the design point number to make the point table, generally to the statistical tables are Excel spreadsheet software to complete, the following figure is the general wiring point statistics , the specific point table may be different from the actual project, will also vary, such as may increase wireless AP points, confidential points, IP voice points (actually data points) and so on.

IDF number	Data	Voice	Fiber
A layer of weak current well	244	28	3
Equipment Layer Weak Current well	444	34	12
Six layer Weak current well	423	19	0
Nine layer Weak current well	431	19	0
12 Layer Weak Current well	52X	18	0
Total:	2400	137	15

4. Various construction deepen drawing design

Each kind of construction deepens the blueprint is the wiring construction premise, you only then completes these drawings, the wiring project also can carry out. In the project implementation, the route is a very important link, it's like the human backbone of the network throughout the wiring system, it mainly includes horizontal cable routing, vertical backbone cable routing, the main wiring between the location, distribution line location, room location, cabinet location, building access line location.

In order to make a physical route map (or pipe line by graph) smoothly, it is necessary to determine the following conditions: It is possible to use galvanized groove, galvanized pipe, etc. on physical routes. Of course will encounter obstacles, such as: brick walls, concrete walls, floor structure, cut and so on, but also need to identify whether the load-bearing wall, not load-bearing walls, to be treated separately. The laying of the way: along the wall lay, laying along the wall, the ceiling, ground laying, etc., but also including route path, material type, material quantity, laying method, construction hours. and routing design must consider other professional route routes, such as building control, security and fire protection.

And then we have to make the room layout plan, to display the wiring cabinets and other network equipment cabinets and the layout of the integrated wiring slots and other information; floor layout diagram, used to view the wiring cabinet and trunk, horizontal line slot position layout; Cabinet Equipment layout diagram, is to show the wiring equipment in the cabinet position layout, of course, these drawings may be in the construction will also change, and in the completion of the drawings in the original drawings on the basis of the modified content, to make the final version of the drawings.
