Matters needing attention in the construction of integrated wiring project

Now home furnishing renovation wiring is a big project, in addition to the laying of wires, TV cable and telephone lines, audio lines, video lines, etc., more and more computer players home network wiring is indispensable. If it is not a professional technician, it is not a simple matter to sort out so many cables. It is also a matter of convenience, safety and beauty in the use of the room. The author estimates that after several years, there is no home network integrated wiring system in the house, just as the current hydropower is not carefully planned out of the house as obsolete, everywhere is the cable tangled together, really cut constantly, and management is chaotic. How to integrate all these professionally known weak cables (including power cables) in an orderly manner in an orderly manner is increasingly becoming a major event in modern home furnishing.

The home integrated wiring system is an electronic system that centralizes the design of televisions, telephones, computer networks, multimedia audio-visual centers, and automatic alarm devices. That is, devices connected to these cables in the home can be controlled by a single device. Previously, However, they are independent. Because the system is different from the ones that provide power (such as power lines), because of their low transmission voltage (generally around 12V), a system like this type of cable is called a weak wiring system. The general integrated wiring system is mainly composed of information access boxes, signal lines, and signal ports. If the integrated wiring system is likened to the home nervous system, the information access box is the brain, and the signal lines and signal ports are nerves and nerve endings. The role of the information distribution box is to control the input and output electronic signals. Signal lines transmit electronic signals. The signal port is connected to the terminal equipment. Such as: televisions, telephones, computers, etc. Generally, the primary information access box can control at least three kinds of electronic signals (such as satellite television), telephone voice signals, and network digital signals (what else does it use?); and higher-level wiring boxes are Can control video, audio (or AV) signals, if your community provides the appropriate services, but also to achieve electronic monitoring, automatic alarm, remote meter reading and other functions of water and electricity.

The system is an integration of a standard connector including a distribution device and various cables and various information outlets. Each component adopts a modular design and a layered star topology, and each function module and line are relatively independent. Or if the line fails, it will not affect the use of other home appliances. The distribution equipment of the household integrated wiring management system is mainly composed of a monitoring module, a computer module, a telephone module, a television module, a video and audio module, and an expansion interface. The functions mainly include access, distribution, transfer, and maintenance management. According to the actual needs of users, they can be flexibly combined and used to support telephone/fax, Internet access, cable TV, home theater, music appreciation, video on demand, fire alarm, security and security, air-conditioning control, lighting control, gas leak alarm and water/ Electric / gas three tables automatically copy (the latter two functions require the community to provide the appropriate service) and other applications. For example, home wiring system is the nervous system of a smart home, and all appliances in the house can be controlled by it. In simple terms, it is a comprehensive weak wiring system for the unified management and use of telephones, computers, televisions, video players, security devices, anti-theft devices, water/electricity/gas automatic meter reading equipment and other information appliances in the future.

Problems to pay attention to during construction

The integrated cabling project is a permanent project, but after your renovation is completed, it is not easy to change. Once there are mistakes and omissions, it is a big trouble: Lamian line does not look good; demolish decoration, redecorate the dark line, too distressed It is not worthwhile. Therefore, in order not to leave troubles and regrets for the future, it is best to pay attention to the following issues in all aspects of construction.

1. Before the construction, fully consider the electrical and lighting equipment required for each functional area, and use this as a basis to roughly calculate the cross-sectional area of ​​the corresponding wire for each road. Should try to use high-quality copper core sheath and install the junction box, in order to avoid aging and breaking, resulting in difficult panel installation.

2. Draw the circuit distribution diagrams of each room, and set the coordinates and heights of various lamps, switches, sockets, and distribution boards to determine the direction of the route and the convergence of branches. It is best to use different colors for wires to identify different circuits.

3. It is better to lay the power cord after it is put through the flame retardant pipe. A power switch shall be provided outside the ceiling of the flammable structure to cut off the power when necessary. All wire connections should be inside the junction box.

4. The total capacity of each branch of the indoor line should not exceed 3,000 watts. The load current of each single-phase loop should be controlled within the proper range. Large households such as air conditioners must set special lines (the power line of the air conditioner should not be less than 5 square).

5, switch installation height is generally from the ground 1200-1350 mm, the socket is generally 200-300 mm, the height of the switchboard is preferably 1800-2000 mm.

If your floor is ready for laying wooden floors, whether composite or solid wood (bamboo), it is recommended that the cables be laid as far as possible on the corners behind the skirting boards, but only at the wall plugs, doorways or through the wall, etc. The line pipe leads to the back of the skirting board. There can be no dead curve in the middle of the line pipe. Leave the lead wire in the pipe. Wait until the floor is finished but the skirting board is not yet installed. After installing the skirting board, you will not see any traces of the traces. It is very beautiful.

This construction method has the following advantages:

1, because the shop floor is carried out in the final stage of the renovation project, when the floor is re-threaded, it can effectively prevent accidental damage to the wire during the long construction period;

2, you can have more time to choose the right wire;

3, when you want to change the line, plus the line can be, remove the skirting board can be constructed, very convenient;

4, because the line pipe does not walk under the floor, so there is no need to cut off the wood keel under the solid wood (bamboo) floor (except for the line pipe and wood keel to match), thereby improving the construction quality, reduce or even avoid the solid wood (bamboo) floor The possibility of stepping on the ring; in the northern region can also prevent the broken keel, solid wood (bamboo) floor joints due to drying and affect the appearance;

5, can save most of the purchase of line management expenses. In fact, workers who lay floors are also reluctant to construct spider-like lines on the ground, because that will affect the speed and quality of construction.

If your floor is paved, it is best to route the line. The function of the line tube is not only to protect the wire, but it also has the function of facilitating line changing. Therefore, in the middle of the embedded pipe, there must be no right-angled corners at first, and the problem of cornering must be solved so that the wires can freely move in the line pipe. Secondly, the line tube is preferably made of plastic coil (a kind of semi-rigid, semi-transparent, and commonly used in the construction of regular buildings), so that there is no joint in the middle of the line pipe, so that the line will not be stuck. If there must be a joint in the middle, use a head-and-head method to insert the joint, and be in the same direction. Then, during the construction period, do not hurry to thread through the line pipe. Instead, thread the lead wire first, and then replace the corresponding wire when the electrical installation is completed.

Last but not least, it is the strong and weak electricity that separates the wiring. The power line is a strong electric power. The greater the load, the stronger the electromagnetic interference generated. Therefore, the power line should be separated from the weak current and low voltage wires as much as possible.

Main problems faced by home integrated wiring

As with any product entering the home, there is a process in which a home-based integrated wiring management system enters the home. From the current stage, there are mainly the following problems:

1. Lack of relevant standards. The home integrated wiring management system is a new concept, because the lack of relevant standards, so the manufacturers are also their own governance, to their own understanding of the integrated wiring production products, the results vary, resulting in the understanding of some products for this group of products On the deviation, and home integrated wiring management system is a direct product to the consumer, so the quality of the product is essential, the lack of standards will make some technical power weak production factory shoddy, causing losses to consumers,

2. Some owners, including some real estate developers and decoration companies, do not understand the product. These people still follow the traditional concept when building or refurbishing. They only focus on the design of the exterior, but they do not have a reasonable plan for the home network—the nervous system in the housing. They just rush to arrange things and can foresee the near future. It will inevitably cause a lot of inconvenience, and once it is found, it will be an irreparable situation. This situation is because the home integrated wiring management system itself is a new concept and needs time for further promotion. Second, households use integrated wiring to invest more than traditional wiring. Before people fully understand it, they have caused some promotion. Difficulties, so this requires the relevant units to do more publicity, allowing users to recognize the important position of integrated wiring in home life, not only for the present, but also for the future.

3. Lack of formal training and experienced construction team. When the owner is renovating, the wiring of the weak electricity is often completed by the plumber of the decoration company, and the decoration company has almost no special weak electrician engineers. Therefore, the construction quality is difficult to guarantee. Therefore, such related companies like decoration companies should grasp the knowledge of home integrated wiring as soon as possible, and the technically qualified construction team is also very beneficial for the promotion of home integrated wiring.

4. Compatible with integrated home wiring, such as broadband access, integrated network services, VOD video on demand and other online services are still lagging behind, making some households less aware of the necessity and urgency of integrated wiring.

In the future, with the rapid development of Internet technologies and information and communication technologies, the wave of informatization and intelligence will rapidly sweep across every corner of the world, and people’s lives will also undergo greater changes. This trend is not only reflected in technology. The update is more important in people's thinking habits. No one can claim that there will be any new technologies and products in smart homes in a few years. However, it is believed that new technologies will create a better life for us.
