Anonymous users2024-02-06The integrated wiring system is the infrastructure of the digital information system for the construction of the intelligent office, and it is a structured wiring system that unifies the planning and design of all voice, data and other systems, providing information and intelligent material medium for the office, and supporting the comprehensive application of voice, data, and more in the future. This article shares some common formulas for integrated wiring, I hope it will be helpful to you.
The demand for RJ-45 heads: m=n*4+n*4*15%.
M: indicates the total demand for RJ-45 connectors.
n: indicates the total amount of leakage at the information point.
n*4*15%: indicates the surplus retained.
Demand for information module: m=n+n*3%.
m: indicates the total demand of the information module.
n: indicates the total number of information points.
n*3%: indicates the surplus.
Amount of line per floor: c=[
l: The distance of the farthest information point from the management room on this floor.
S: The closest information point to the management room on this floor is blind away from the letter search.
n: The total number of information points on this floor.
Standby factor. 6: Termination tolerance.
When selecting a trunking, the cross-sectional area of the trunking = the horizontal cable area of 3
1. (Longest line spacing + shortest line spacing) 2 = Average.
Average + 5 meters) x number of points = total length.
Total length 305 (standard meters per box) + 2 boxes = total number of boxes.
The number can also be set by yourself, and if it is the first time, it is better to prepare more than afterwards.
2. Each service requires a 4-pair unshielded twisted pair cable or a 2-core (micron multi-mode) optical cable;
The total number of horizontal cables in each booth = (number of workspaces served by the booth) * (number of services provided by each workspace).
Workspace Horizontal Cabling Calculations:
a: the distance of the nearest information point;
b: the distance of the farthest information point;
c: The number of information points in the work area of each layer.
Required cable length for each layer = (a+b) 2*
The total number of cable boxes required = the sum of the cable lengths of each layer is 305 meters.
3. c = [c the amount of thread used on each floor.
f is the distance between the farthest information socket and the wiring room.
n is the distance between the nearest information socket and the wiring room.
n is the number of information sockets on each layer.
Simple formula:
1.(Longest line spacing + shortest line spacing) 2* flat** long.
Flat**length*information points = total number of cables required.
Total number of cables 305 = how many boxes are needed.
2.Number of lines: (longest + shortest) Floor height.
Number of boxes: number of lines x number of information points 305
3.(Max Distance + Minimum Distance) 2 * Layer Height) * Number of Nodes) 305 = Number of Cable Boxes.
Where: the coefficient is the loss; Floor height is the height of the floor, which must be calculated if the horizontal trunking goes to the ceiling; If it is an raised floor, it can be ignored; 305 is 1000 feet conversion.
4.The average of the longest and shortest cables x the total number of points, plus 10% redundancy.

n: indicates the total number of information rental guess points.
n*4*15%: indicates the surplus retained.
Demand for information module: m=n+n*3%.
m: indicates the total demand of the information module.
n: indicates the total number of gestures shouted at the information point.
n*3%: indicates the surplus.
Amount of line per floor: c=[
l: The distance of the farthest information point from the management room on this floor.
s: The distance between the nearest information point on this floor and the management room.
n: The total number of credit and fraud book interest points on this floor.

Anonymous users2024-02-041. The integrated cable laying project is a sub-project in the installation project, which generally refers to the data cable laying (weak current cable).
2. The calculation is based on the national quota, and the current national standard for your problem is the 2008 version of the national standard installation quota. (Varies slightly from province to province).
3. General calculation.
Many people don't know what the integrated wiring system is, so let's introduce it below. >>>More
To put it simply, it's one of the lines that undertakes the whole system, the trunk line, the backbone line, like your central nervous system, the subline is the line that branches from the trunk to the endpoints, like your neural pathway, the computer room is like the brain, and the five senses are like the endpoints, you see???
Weakly electrical? Weak current includes a lot of content, such as power cables, data cables, etc., what tube to wear, tube size, tube placement, path. Wait a minute. You can find the relevant documents in the library, and it will be clearer.
