Some of the home Wiring management system
Often the renovation project once the action on the complicated affairs, so that we can not give enough attention to this aspect of the integrated wiring (or not). The construction side, not to mention, now on the renovation market only a very few construction teams can have professional electricians to provide you with formal electrical construction. If these hidden works are not handled properly, and you do not monitor the situation, it will bring a lot of worries and regrets, and even irreparable damage to the future use after moving in. Therefore, it is necessary to understand and master some knowledge of integrated home network wiring, so as to avoid future losses and regrets. I believe that everyone does not want to forget to install a socket or connect a section of cable in a key location, and they have just renovated the new home in the wall, labor and effort it.
One, the family network integrated wiring system
Family integrated wiring system is the television, telephone, computer networks, multimedia audio-visual centers, automatic alarms, etc. designed to centralize the control of the electronic system, that is, the family by the cable connected to the equipment can be centrally controlled by an appliance, before they are "their own way! They used to be "separate". Because the system is different from the provision of electrical energy (such as power lines), because they do not have a high transmission voltage (generally in the 12V or so), so the system composed of such cables is known as the weak power cabling system. General integrated wiring system mainly consists of information access box, signal lines and signal ports, if the integrated wiring system is compared to the home nervous system, information access box is the brain, and signal lines and signal ports are nerves and nerve endings. The role of the information wiring box is to control the input and output of electronic signals. Signal lines transmit electronic signals. The signal port connects the terminal equipment. For example: television sets, telephones, computers and so on. Generally more primary information access box can control at least cable television signals (including satellite television, of course), telephone voice signals and network digital signals of the three electronic signals (or else what do you want it for?). While the more advanced distribution box can control video, audio (or AV) signals, if your community to provide the appropriate services, but also to achieve electronic monitoring, automatic alarms, remote reading of water, electricity and gas meters and a series of functions.
A typical household integrated wiring system is composed of schematic diagrams as shown in Figure 1:
Figure 1: Household integrated wiring system schematic diagram
The system is a distribution device and a variety of cables as well as various information out of the standard connector integration, the components of the modular design and hierarchical star topology, the various functional modules and lines are relatively Independence, a single home appliance equipment or line failure will not affect the use of other home appliances. The distribution device of home integrated wiring management system is mainly composed of monitoring module, computer module, telephone module, TV module, audio-visual module and expansion interface, etc. The functions are mainly access, distribution, transfer and maintenance management. According to the user's actual needs, can be flexibly combined, use, so as to support telephone / fax, Internet access, cable TV, home theater, music appreciation, video on demand, fire alarm, security, air conditioning self-control, lighting control, gas leakage alarms and water / electricity / gas meter automatic reading (the latter two functions need to be able to provide the appropriate community services) and other applications. Let's say that the home wiring system is a smart home residential "nervous system", all the electrical equipment in the residence can be unified through it to control. Simply put, it is a unified management and use of telephones, computers, televisions, DVD players, security equipment, anti-theft equipment, water/electricity/gas automatic meter reading equipment and other information about the future of the home appliances of the integrated weak wiring system.
Two, integrated wiring is the development trend of home improvement
Now there are many places are in the establishment of community broadband network or metropolitan broadband network, which will make the cable television network, computer network, telephone network, three networks, to provide integrated services for the public. With the continuous improvement of living standards, modern family entertainment, communication, security and protection needs continue to grow and put forward higher requirements, the gradual popularization of notebooks, people at home in various rooms to be able to access the Internet, can work at home, automated control of a variety of home appliances and equipment, which requires a unified home network. Family integrated wiring has become an urgent need, so the use of standardized home wiring system has gradually become the fourth essential family infrastructure after water, electricity and gas.
With the further improvement of people's living standards, in the near future, it is estimated that the use of integrated home wiring will not be as incredible as no water, electricity, gas, home wiring will become as essential as water, electricity, gas.
In the modern family, the weak cable more and more: if the home has several computers, the interconnection of the network cable is quite a lot. These often bring too many lines to the family, too chaotic troubles, if the use of home integrated wiring management system to pre-embed all the weak cable, you can save the trouble of pulling the wire later, but also to ensure that the beauty and consistency of home decoration.
With the rapid development and popularization of broadband networks, many cities in China now open broadband IP MAN or broadband information community has begun to enter the ordinary family. However, now like this broadband application is only to provide "broadband to the home" option, and only to solve the home of the weak wiring can be considered a real thorough solution to the "broadband to the desktop" problem,
With the computer technology, communications technology, automation technology and other multidisciplinary technology. With the development of computer technology, communications technology, automation technology and other multidisciplinary development and integration, the family will be in the near future to truly realize the intelligence, the use of households within the family telephone, television, computers and other tools through the home integrated wiring management system will be electricity, water, gas and other equipment into one, and connected to the Internet to achieve self-control, management, and to achieve such as home burglary, disaster prevention, alarms, home appliances through the Internet remote control, and other powerful functions, and with the network integrated business services, the network can only be considered a complete solution to the problem of "broadband to the desktop". Functions, and with the development of network integrated business, will realize such as VOD video on demand, online shopping, SOHO home office, remote education, telemedicine, etc., so that the family can really high enjoyment of work, study and recreation, therefore, home integrated wiring management system as the basis for the construction of the family network should include the broadband Internet, the home Internet and home control network and so on, the relationship between the three is: broadband Internet, home Internet and home control network. The relationship between the three is: broadband Internet is the family's external bridge, to achieve communication and interaction with the outside world, the family Internet is the information home appliances network foundation and a good connection with the Internet, control network is a variety of home appliances and equipment control, play a complementary role in the first two networks. Family in the integrated wiring, to have a certain degree of awareness of the three networks of the family in advance to meet the upcoming family intelligence.
Overall, compared with the traditional wiring method, the use of home integrated wiring system for home wiring at least has the following advantages:
1, standardized construction, can ensure the quality and performance;
2, the use of unified control and management, in the future, daily life, the use of the use of, management and maintenance is very convenient;
3, system compatibility Good, no matter which choice of network cabling equipment, can provide support;
4, scalable, flexible combination of all the "information points" are common, add new equipment or appliances, can be connected to the use of immediately.
The use of home integrated wiring management system on the one hand to meet the current demand, but also fully adapt to the future needs of intelligent home life.
Three, integrated wiring project examples
A set of four rooms, two halls and two baths of the house type, for example, in the planning program throughout the living room in the information points have 35, 28 information panels, a variety of specifications for a number of cables. Specific distribution is shown in Figure 2 below.
Figure 2: Distribution of information points and panels
The functions that can be realized by this program are as follows:
1. Cable TV interfaces are installed in the living room, the master bedroom, the study, and the children's room, so that they can watch the cable TV programs individually.
2, where there is an AV outlet can be simultaneously **** enjoy a DVD player (VCR / VCD / DVD) and a satellite TV receiver. This can reduce the purchase cost of the DVD player, thus reducing the cost of updating the DVD player; can reduce the space where the DVD player is placed, and do not have to move the player frequently; there is also the advantage that parents can also control the source of the program, to prevent minor children from watching unhealthy content in the room, and its broadcast content is controlled by the parents; in addition to the audio-video system can be broadcast through the satellite TV program to all rooms.
3, you can through the master bedroom, study, children's room remote control receiver to control the living room audio, DVD player, electric curtains and other remotely controllable equipment. For example, you can use the remote control in the master bedroom to control the playback menu of the movie player in the living room.
4, living room, master bedroom, study, children's room, kitchen, etc. are five types of network cable to reach, you can choose to access the Internet in different locations; but also for the network appliances access to the use of the interface is reserved. Through the network switch, you can form a family LAN, so as to realize the function of resource **** enjoyment, network games, etc. Of course, we can also set up for multiple applications to access the Internet at the same time (if you have a refrigerator that can access the Internet). There is a cable jack in the study, not only can you use the computer to watch TV, but you may also want to use CableModem in the future.
5. The living room, master bedroom, study, children's room, kitchen and public bathroom are all connected to the telephone. Through the program-controlled telephone exchange, each extension can realize the internal call, transfer and substitute; computer operator function can be set up; the main telephone can restrict the function of other extensions and many other functions. We can even achieve the effect of "Hello, this is the home of ※※※※, please press 1 for living room, press 2 for toilet, and dial 0 for checking number" when someone calls, which ensures that the owner can receive the call within two steps from any position in the room.
6. Users can adjust and manage each line on demand at any time. For example, parents can cut off the output of any line at any time to ensure that school children can not use the phone, TV, computers, etc. during study time; a line can be changed from telephone to data, thus changing the use of the function and so on.
However, such a comprehensive wiring management system can be no control of traditional refrigerators, washing machines can, wiring program involved in the home appliances are only: computers, projectors (or television sets), telephones, motorized screens, TV antennas, motorized curtains, video disc players and so on. If you choose to mold the information appliances connected to the intelligent home system, including network appliances (such as Haier's network refrigerator, network microwave ovens, etc.) can be achieved throughout the living room centralized control.
1, pre-engineering preparation
Pre-engineering preparation for the entire project is crucial. From the placement of electrical appliances design to the design and construction of wiring, a little sloppy, so the first thing we need to do is to draw a plan of the room, and then all the planned information points marked on the map, and then need to be connected to the line drawn to the map, and roughly calculate the length of the various cables (there is a principle of preferring to be long rather than short). The purchase of materials to PVC pipe and a variety of wire-based, wire requirements: strong, good quality. Network cable, of course, needless to say, regardless of whether the future need for 1000M speed, it is best to buy super 5 twisted-pair cable, telephone line will be used directly instead of twisted-pair cable. Because a variety of cables to be buried in the ground or the wall for long-term use, can not be replaced at will, therefore, the quality of the cable is particularly important, do not want to save money, but should be purchased from the regular channels of the cable, in order to avoid future problems. If the home furnishing budget is not sufficiently generous, in the purchase of home integrated wiring management system, you can first install a standard type "smart home wiring box", and planning, paving enough lines, set up a basic smart home wiring system, so that both can be used right away, in the future, you can also conveniently replace the configuration of a more powerful intelligent wiring box. . Each family according to their ability, family intelligent construction should be based on the "practical-oriented, appropriate ahead of the" principle, according to the actual demand and spending power, choose the solution.
2, start engineering construction
In accordance with our preconceived notions, all the wires that need to be prepared will be purchased back to be classified, and then in the two ends of the wire labeled accordingly (this is very important). After that we sort the wires that go on a route, after that you will get simple bundles of wires and just arrange them according to your plan. As for where to place the integrated wiring management system in your home, it's up to your convenience, it's fine to place it in the study, or hidden in the corner of the living room. Here to remind you, the wiring is inevitable in the wall, the ground holes chiseling groove, but for your safety and the safety of others, this work is best carried out in accordance with the provisions of the property sector. Be careful, the telephone line in the bathroom outlet must be close to the toilet, otherwise there is no point (toilet phone is not to solve the urgent need to go out in a hurry to answer the phone ah).
Be sure to check the connectivity of the wires before you put them in, and then realize that it's a problem. Another point to note, it is best to make all the joints at the end of the production, a lot of special joints, in the threading before the most can only make a head, if two are made out of the wear through the past. It's best to get professional help to make the connectors for specialty cables like network cables for computers.
After the completion of the renovation project, then you can carry out the connection of various equipment. We need to prepare the tools in addition to pliers and cones in addition to the installation of telephone line crystal head of the professional wire clamp, installation of network cable crystal head of the professional wire clamp. Install a telephone in each room and set up on the switchboard.
Four, the construction should pay attention to the problem
Comprehensive wiring project is a permanent project, but not easy to change after the completion of your renovation, once there are mistakes and omissions, but it is a big trouble: pulling the open wire, does not look good; demolition of the decoration, reclothing the dark line, too much pain, and is not cost-effective. Therefore, in order not to leave worries and regrets in the future, in all aspects of construction, it is best to pay attention to the following aspects of the problem.
1, before construction, we should fully consider the functional areas of the required electrical appliances and lighting equipment, and as a basis for roughly calculating the corresponding matching wire cross-section area of each circuit. Should try to use high-quality copper core sheath and installation of junction boxes to avoid aging and breakage, resulting in panel installation difficulties.
2, drawing the distribution of each room circuit diagrams, and will be a variety of lamps, switches, sockets and switchboard coordinates and height to determine the route to the direction and branching convergence. Wire is best to use different colors in order to identify different circuits.
3, it is best to power lines outside the flame-retardant pipe before laying. In the combustible structure of the roof should be set outside the power switch for necessary cut off the power supply. All the connectors of the wire should be in the junction box.
4, indoor lines should not exceed 3000 watts of total capacity of each sub-circuit, each single-phase circuit load current should be controlled in the appropriate range, air conditioning and other household power users must be set up special line (air-conditioning power line is best not less than 5 "square").
5, the switch installation height is generally 1200-1350 mm from the ground, the socket is generally 200-300 mm, the height of the switchboard to 1800-2000 mm is appropriate.
If your floor is ready to lay wood flooring, whether composite or solid wood (bamboo), it is recommended that as far as possible, the wire cloth in the corner behind the skirting board, just in the wall plug, doorway, or through the wall parts of the pre-buried a small section of the line through to the skirting board behind the middle of the line pipe can not be a dead end, the pipe left a good lead wire, wait until the flooring is finished but not yet installed when skirting boards and then put the wire through Inside. After installing the skirting board, you will not see any traces of wiring, very beautiful.
This construction method has the following advantages:
1, because the flooring is in the final stage of the renovation project, and then threaded when the flooring 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 wire, add wire Can, remove the skirting board can be constructed, very convenient;
4, because the line does not go under the floor, so do not have to cut off the solid wood (bamboo) floor under the wooden keel (except for the line and the wooden keel towards the same person), thus improving the quality of the construction, to reduce or even avoid the solid wood (bamboo) flooring on the floor on a step on the ringing of the possibility of the north can also prevent the broken keel place, solid wood (bamboo) flooring Seams become larger due to drying and affect the beauty;
5, can save most of the expenses to buy wire pipe. In fact, the flooring workers are not willing to construction floor covered with cobweb-like wire pipe, because that will affect the construction speed and quality.
If your floor is tiled, wiring is best to pre-buried wire pipe. The role of the wire pipe is not only to protect the wire, it also has the function of easy to change the wire. Therefore, the pre-buried wire pipe in the middle of the first can not have a right-angle dead end, to solve the problem of bending, so that the wire can be stretched freely in the line pipe. Secondly, it is best to use plastic coil (a kind of semi-hard, semi-transparent, regular building construction of the kind commonly used), so that there is no joints in the middle of the line pipe, so that when threading will not be stuck line. If there must be a joint in the middle, but also to use the size of the head of the method of plugging, and to the same direction. Then there is the construction period in the wire pipe do not rush through the wire, but first threaded into the lead wire, wait until the final installation of the electrical and then replaced with the appropriate wire.
The last thing to emphasize is the strong and weak power to separate wiring. Power lines belong to the strong electricity, connected to the greater the load, the electromagnetic wave generated by the interference is also the stronger, so the power line should be weak current and low voltage wires as far as possible to go separately.
Fifth, the main problems faced by the home integrated wiring
With any kind of product into the home, home integrated wiring management system into the home there will be a process, from the current stage there are several problems:
1. Lack of relevant standards. Home integrated wiring management system is a new concept, because of the lack of relevant standards, so the manufacturers are their own, to their own understanding of integrated wiring production products, the results are different, which caused some of the crowd on the understanding of this type of product bias, and the home integrated wiring management system is a direct face to the consumer's products, so the quality of the product is critical, the lack of standards will make some of the The lack of standards will make some of the weak technical force of the production plant crude, to bring losses to consumers,
2. Some owners, including some real estate developers and decoration companies do not understand the product. These people in the construction or renovation of the house is still made according to the traditional concept, only focus on the appearance of the design, but for the family network - housing in the "nervous system" but no reasonable planning, just hastily arranged things, can be predicted that the near future will certainly cause a lot of inconvenience, and once the problem is found, it will cause a lot of inconvenience. A lot of inconvenience, and once the problem is found, but will be unable to make up for the situation. This situation is because the home integrated wiring management system itself is a new concept, need time for further promotion, the second is the use of integrated wiring for the family than the traditional wiring will be more invested in some, before people still do not fully understand also caused some difficulties in the promotion, so this requires the relevant units to do more publicity, so that users recognize the important position of integrated wiring in the home life, not only for the sake of the present, but also for the sake of the future. For the future.
3. Lack of formal training, experienced construction team. Homeowners in the renovation, weak wiring is often completed by the decoration company's plumbers and electricians, and the decoration company almost no specialized weak engineer, so it is difficult to guarantee the quality of construction. Therefore, like the decoration company such related units should be as soon as possible to master the relevant knowledge of the family integrated wiring, and technically qualified construction team for the promotion of the family integrated wiring is also very favorable.
4. With the family integrated wiring supporting such as broadband access, network integrated services, VOD video on demand and other online services are still relatively lagging behind, also makes some families do not realize the need for integrated wiring and urgency.

In the future, with the rapid development of Internet technology and information and communication technology, information technology, intelligent wave will be swept more quickly in every corner of the world, people's lives will undergo greater changes, this trend is not only embodied in the update of technology, but more importantly, is also embodied in people's habits of mind. Who can not assert that in a few years in the smart home and what new technologies and products appear, but can believe that the new technology will create a better quality of life for us.
