Generic Cabling Construction Specification

There are still many things worth learning about in terms of Integrated Wiring construction specifications. Here we mainly introduce home decoration and wiring experience, including introduction of Weak Current Wiring and specific lines, I would like to share with you some help.

Special requirements for Integrated Wiring Construction Specifications: the distance between strong and weak current pipe slots is more than 30 cm. This will increase the labor force for workers, but in order not to be depressed in the future, we require workers to do so, this is because there is interference between strong and weak current cables. In addition, our sockets are located less than 80 cm away from the ground, because we are afraid that we can easily see the wires at a height, which is not beautiful. Our kitchen is a whole cabinet. When the workers put on the water and electricity, they asked the Cabinet company to determine the water and electricity position of the kitchen. Although the Cabinet company has designed the water and electricity, however, we still have three more sockets in the kitchen, so we are afraid that we will add more things in the future. If we want to make cabling again after the decoration, it will be totally different. It is hard to pull the bright lines and remove and relay the hidden lines, not only are people depressed, but they are not cost-effective.

1. install more sockets. There must be a socket in the stairwell. Do not design sockets next to the furnace hood, which poses security risks.
2. Do not place the switch on or off the door in a narrow distance.
3. It is best to design a dual-controller light in the aisle. This light is turned on and the other light is turned off.
4. It is best to buy a plug with a panel. Some sockets that are not used for a long time are not easy to be damaged.
5. the dining room lamp should be placed at the dining table; otherwise, the lamp is not in the middle of the dining table.
6. A transformer must be installed for a small spotlight. Without a transformer, the light will be like a small bomb that will explode at any time. The final result is that it will never be turned on.
7. Buy More sockets with two eyes and less electrical appliances with three eyes.
8. cable outlets need to buy broadband.
9. The location of the original sewer pipe and floor drain should not be changed. If it is not easy to change, it is the easiest way to get flushed.
10. The electrical pipeline has just been laid out, and the workers are asked to draw a line chart before sealing the trough.
11. During the construction process, I tried my best to look at it and immediately asked the workers to change it if I found it inappropriate. I was afraid that it would be too late to wait until the next process is finished, saving my worries about rework.
12. In order to save power, you must accurately plan the sockets for low-power electrical appliances (such as TVs, DVD machines, microwave ovens, air conditioners, and DVD machines. If you do not unplug the plug, it is best to install the switch socket panel for the DD in the STANDBY state, because the power consumed by the standby mode cannot be read from the ordinary electric meter, but the time-sharing electric meter will read it.
13. After threading the pipe, close the pipe in the cable trough, and use cement mortar to encapsulate the wire box firmly. The joint port should be slightly lower than the wall 5cm MPa and keep it correct. The Master said, don't look at the current transformation of this plug-in line is so simple, threading is more important than that, such as air conditioning and other high-power electrical appliances have to go alone, and now the general communication line also needs to go through the dark line, when going through a dark line, the communication line should not only walk along with the line of the power line, but also maintain a distance of more than 50 cm. Otherwise, electromagnetic interference will occur.

Experiences in home decoration and wiring-writing to friends who are decorating or will be decorating

There are many wires that need to be hidden in the home decoration. The most common cables are power cables, telephone lines, network lines, TV signal lines, and audio systems in our audio room. It is often complicated to decorate, so we cannot pay enough attention to this part. Construction parties should not mention that there are very few professional electricians to provide you with formal electrical construction. If these concealed projects are not properly handled, they will bring endless troubles and even irreversible losses to future electrical construction and use after occupancy. Therefore, it is necessary for us to understand and master some decoration knowledge, so as not to regret it!

There should be a necessary design before the electrical construction, although there will inevitably be modifications in the specific construction process, but this design must be there. The general principle of electrical appliance design is that the weak current enables strong electricity, and the strong current enables equipment. However, the convenience of Weak Current Wiring should be considered as much as possible during the specific design.

Specific to the wiring construction, if your ground is floor laying, whether it is composite or solid wood bamboo), I suggest you try your best to put the wire in the corner behind the skirting board, only a small wire pipe is embedded in the wall plug, door, or wall-crossing area to the back of the skirting board. No dead bend can be found in the middle of the pipe. Wire wires are placed in the pipe, wait until the floor is paved but the skirting board is not installed. After the skirting board is installed, you will not see any trace of cabling, which is very beautiful. This construction method has the following advantages: 1. Because the floor laying is carried out at the final stage of the decoration project, the floor will be laid again when the floor is laid, it can effectively prevent accidental damage to cables during long construction periods; 2. You can have more time to choose the appropriate cables; 3. When do you want to change the cables and add cables? You can remove the skirting boards and construct them conveniently. 4. Because the pipe line does not walk under the floor, you do not have to cut off solid wood bamboo) except for those with the same direction as the wooden keel pipe under the floor), which improves the construction quality, reduces or even avoids the possibility of solid wood bamboo floor ringing upon a step; in the northern region, the solid wood bamboo (solid wood bamboo) joint can also prevent the keel from being broken and affect the appearance due to the drying. 5. You can save most of the expenses for pipeline purchasing. In fact, the floor laying workers do not want to build the ground to be full of spider-like pipe lines, because it will affect the construction speed and quality. This is a construction method benefiting both parties.

If your floor is made of floor tiles, it is best to overlay the line pipe for cabling. The purpose of a pipe is not only to protect the wire, but also to facilitate the replacement of the wire. Therefore, the middle of the pre-Buried Pipe Line cannot have a right-angle dead bend. It is necessary to solve the turning problem by means of a nest bend, so that the wire can freely rotate in the online tube. That is to say, we need to turn the pipe line into an arc with a radius not less than 15cm to complete various angle turns. However, the corner is quite special. We need to nest two 1/4 circles to turn the 90 ° bend into a bend-the first 1/4 circle turns forward to left or right, the second 1/4 circle converts the horizontal direction to vertical. Only in this way can the 90 ° curve of two vertical planes be completed. See. The nest bend spring can be bent on any part of the wire or wire .)

Smart Home Integrated Wiring Construction Specification

I. general AV cabling requirements:

1. You can use three common video cables and audio cables for the traffic distribution line. Generally ~ Signal Attenuation within 10 meters is negligible;
2. the structure of the video + L/R audio line is different from that of the AV line. The AV line is a shielding structure, while the audio line does not have a shielding structure. The video line in the AV line has higher requirements, therefore, you must understand what terminals and devices are connected to during cabling;
3. The M-terminal cable degrades greatly with distance, so it is not recommended for long-distance transmission;
4. Generally, cable TV frequency divider has no amplification function, even if the PBA structure is used internally, it does not;
5. It is best to ask the satellite TV company about the pre-embedded cable of satellite TV in advance. Otherwise, the cable may be incorrectly wired.

II. General wiring construction specifications for devices with Weak Current Wiring:

1. Multiple AV signal distribution modules
2. Multiple telephone distributors
3. Cable TV multi-channel distributor
4. satellite signal dual-path distributor
5. satellite signal amplifier
6. network switch (8 ports)
7. Background Music switching panel and Controller
8. Red Tooth receiving, launch panel, and Red Tooth host

Iii. Specific line solutions for Integrated Wiring Construction Specifications

1. Wiring of surround speakers

If you are not a enthusiast, the audio wiring is not complicated. Just set your own TV and audio positions, and pre-bury the wires surrounding the speaker in the wall, with both ends on both sides of the sofa, one end is located on the wall behind the TV, and the position of the power amplifier is not included in the rear of the Power Amplifier. You can connect the end to the end by using an operator column. You only need to use two channels and four surround speakers. The main speaker, central speaker, and ultra-heavy bass are generally placed on the front without embedding lines. The sound box is generally a transparent multi-core copper wire, and the advanced fever wire is oxygen-free copper. Generally, the more cores, the better, such as 200 cores, at least more than 50 cores. The price is about 3-5 yuan a meter. For high-end products, more than 50 are required.

2. Satellite Receiving Antenna Solution

A. Feasible Methods:
Preset the satellite antenna interface on the balcony, and then distribute the signal to each room through the satellite signal distributor. If you want to watch satellite TV, you need a satellite TV receiver in this room. Note: It is best to connect the satellite TV signal line to the receiver directly. Do not use the wiring panel to prevent signal attenuation)

B. More advanced and complex) method:
Purpose: To mix satellite signals into the cable TV signals in the room. In this way, you can only make wired cabling in the room and watch satellite TV through wired cables.
Disadvantage: You still have to go to the satellite receiver side to select channels, so I think it is not particularly practical for ordinary residents.
Method:
1. Satellite receivers require RF output. Now many Cost-down models have simplified RF output.
2. RF output modulation in the ultra-high frequency band and adjustable to avoid interference with cable TV.
3. Connect the satellite RF to the cable TV portal and use a high-quality binary distributor as a mixer to mix the satellite TV into the cable TV. High quality --> open the lid and use wires to directly connect to the lid. At least the capacitor, inductance, and PCB can be used ).
4. The second distributor is a passive device and provides one-way transmission without interfering with neighbors.
5. If the quality of some RF transmitters is poor, it may interfere with cable TVs of other channels.
6. After the channel is connected, the output channel is fine tuned, and the image sound is clear. Other channels do not interfere.

3. Connection between computers and TVs

Now, many families have begun to consider flat-screen TVs when buying TV sets, which provides convenience for computer signals to be transferred to TVs. think about it. Transfer the computer signal of the study or the notebook signal in the bedroom to the flat-screen TV in the living room or bedroom, and use a Bluetooth keyboard and mouse to directly control how nice it is on the sofa or bed.

VGA or DVI cables are used for laying the cables (HDMI is not considered for the time being ). generally, the vgaine is divided into 3 + 4 and 3 + 6 types. The price is almost 5 yuan up or down a meter, and the price is about 10 yuan a meter. about DVI, DVI-D and DVI-I. (The DVI-A has been ignored ). in general, the graphics card is DVI-I interface, and many flat panel TV is DVI-D interface. DVI-I interface although compatible with the DVI-D interface, but the DVI-I plug is not plugged into the DVI-D interface. But you can use a DVI-I to convert a DVI-D to a converter. The price of the DVI line ranges from 20 yuan to Yuan per meter. It is enough to use 40 to 50 yuan per meter.

4. Selection of integrated distribution boxes for household Weak Current

This is also the most critical aspect of the overall wiring construction specification, which is directly related to whether it can be used in the future and whether it can be upgraded. In fact, the key to selection of cabling boxes is

1. Volume. Needless to say, the larger the volume, the more features.

2. is it modular or finished. modularization means that the devices, such as telephones and networks, are manufacturer-specific modules. the advantage is beautiful. the disadvantage is that once the product breaks down in the future, the product can only be purchased from the manufacturer and cannot be purchased from the market. finished production means that all the devices in the product use the existing manufacturer's equipment. For example, the network can be 3COM, DLINK, or TPLINK. the phone number can be TCL or Weixin. the disadvantage is that after the installation is complete, there is no modular look inside. In fact, the biggest advantage of finished products is that the upgrade space is large and new devices will be available in the future, you can purchase any device on the market for replacement with the integrated wiring box at any time.

3. function. the basic requirements are telephone, network, and cable TV (broadband distribution is required ). AV sharing and redteeth control are required. for example, security protection, lighting control, and home appliance control are not in the scope of the weak current integrated wiring box. You can learn more about the digital home integration solution of xiaoxianju launched by China's digital decoration network. Free on-site installation nationwide.

4. Price. The wise, the wise, the wise

5. About the digital TV set-top box sharing
Now the digital process of cable TV is in progress all over the country. If we plan to share it, we need to adopt AV cabling, because the digital set-top box uses avoutput, but AV cabling must be combined with infrared control, otherwise, you have to go out and change the digital set-top box in the bedroom. at present, AV sharing is not perfect, that is, it is impossible to watch different TVs at different points. AV sharing not only shares digital set-top boxes, but also includes DVDs and satellite TVs. Of course, it can also be used as an output of common backgrounds. avoutputs are divided into multiple types of devices, and common AV devices can input multiple outputs one way. mid-range users can input multiple (identical) outputs. high-end multi-channel input and multi-channel (different) outputs can also be remotely controlled. the customer determines the specific device to use.

Home Background Music System

If you want to use another independent output of the Power Amplifier as the background music, you need to connect the audio cable behind the power amplifier until you need to install the background music speaker. Most of them are currently stereo music, so we need to connect two wires at the same time. Note that the audio cable is not a sound box line, the audio cable is the signal line that is usually connected to VCD/DVD at home, and the connector is a lotus flower plug.

6. Ceiling speaker. Very cheap

General method:
Place the Power Amplifier in the living room or bedroom to connect the audio cable to the bathroom or kitchen. Install ceiling speakers in the bathroom or kitchen.

One statement:
Ordinary white ceiling speaker in fact tone General (except for high-grade. here specifically within a hundred yuan), it is best to buy a car speaker to replace the black mesh ). Car speakers are marked with clear indicators, such as 35 ~ 2 KHZ, 50 W, and so on, and many brands do not have ceiling speakers. However, the installation method of the car speaker is different from that of the ceiling speaker. The ceiling speaker has a special device, while the car speaker only has a mesh cover and screw holes, but the installation should not be a problem. As for anti-DDoS, the problem should not be very high, of course, the price is also different.

Another statement:
It is replaced by an active speaker, and the audio cable is wired. A small partition is placed on the wall, and a power outlet with a switch is placed next to it. The active speaker is placed on the partition. In this way, audio source signals such as CD can be directly sent to the source speaker without using the power amplifier. at ordinary times, the volume of the source speaker is adjusted to the appropriate position, and the switch of the source speaker is on, insert the source speaker outlet into the socket panel with a switch. open the panel switch when you want to listen. The sound quality of a good source speaker is higher than that of a ceiling speaker.

Iv. general wiring Construction Specifications weak current construction specifications and steps

1. determine the point

1. The basis for determining the position: According to the home wiring design drawing, combined with the point on the wall, the position of the hidden box at each point is marked with a pencil, ruler, or ink bucket.
2. determine the height of the hidden box: Except for special requirements, the height of the hidden box is the same as that of the original strong electrical outlet, and the height of the background music tuning switch should be the same as that of the original strong electrical switch. If multiple hidden boxes exist together, the distance between the hidden boxes should be at least 10mm.
3. determine the location of the cabling box:

1) embedded layout: increase the size of the Weak Current Wiring box by 10mm for each of the widths and heights, and decrease the size by 10mm for the depth direction.
2) External: Mark the position of the fixed hole according to the model size of the product used.
3) built-in: determine the height of the product to which the pipeline enters.

Ii. Slotted

1. Determine the slotted route according to the following principles:
(1) Principle of shortest route;
(2) do not undermine the original strong electricity principle;
(3) do not damage the waterproof principle.
2. Determine the slotted width: determine the number of PVC pipes based on the signal line, and then determine the width of the slot.
3. Determine the groove depth: If 16mm PVC pipe is selected, the groove depth is 20mm. If 20mm PVC pipe is selected, the groove depth is 25mm.
4. Cable trough appearance requirements: horizontal and vertical, uniform size.
