Main points and experience of integrated wiring construction

Integrated wiring Market rapid development, many enterprises, communities and families are beginning to introduce a comprehensive wiring system, however, after all, this market is still a development of the market, so the specific construction quality wiring has a lot of problems, I believe in this, many business people and home users are deeply touched, For example, more and more family enterprises in order to achieve a variety of business requirements, as far as possible to reduce the expenses of enterprises, everything must be hands-on, the network cabling system in each room should pay attention to what is worth pondering in the implementation process.

You should know before the commencement

Generally speaking, the network cabling system can be divided into telephone line wiring, integrated wiring and Ethernet cabling three categories, which are suitable for different environmental conditions, users should have a basic understanding of them before the commencement of construction.

Traditional telephone line wiring system is also known as "household Line project", because the system is mainly used for transmission of voice signals and narrowband data signals, generally using a pair of copper wire to achieve long-distance transmission, distance can reach 3~5 kilometers. This wiring can be from the area of the computer room laying large logarithm copper cable to the community, a community based on the size of a few points, from the point of contact to the building Unit set wiring box, if there is a user to install the phone, from the wiring box directly into the door, the wiring project has a simple construction, the construction process requirements are not high, can be long-distance transmission characteristics. ---http://bianceng.cn (computer science)

Intelligent building wiring is also known as integrated wiring, it is a system integration center through the integrated wiring system will be office automation system, communication automation system and power, fire, security, lighting, air-conditioning and other security monitoring automation system, to achieve the purpose of information management. This wiring project is generally implemented in one or several office buildings, with information points diversity, unit area information points dense (2 information points/10 square meters), transmission bandwidth requirements of high characteristics.

Community Ethernet cabling using star structure, through the "Fiber + five Lines" approach, generally in several or dozens of residential buildings, to provide users with high-speed broadband interface. Community Ethernet Cabling has five types of line transmission distance short (only 100 meters), construction technology requires high characteristics, compared with the integrated wiring, community Ethernet cabling Information point single, less per unit area information points, line environment is poor, but the Ethernet access technology is very mature, standardized, average port cost low, high bandwidth, Low cost of client equipment, is the current wiring hotspot.

Wiring preparation and step experience

Usually network engineering after investigation, to determine the scheme, the next step is the implementation of the project, and the first step is the implementation of the project before the preparatory work: the design of integrated wiring of the actual construction map, to determine the location of wiring, need to consider such as: concealment, damage to the building (structural characteristics) In the use of existing space at the same time to avoid power lines and other lines, the scene of the cable and other necessary and effective protection needs, construction workload and feasibility (such as hitting the wall, etc.), and so on, and then the drawings provided to the construction personnel, supervisors and supervisors to use;

Then the planning and design and budget, according to the above situation to determine the route and apply for approval, such as the need to hit the load-bearing beam on the wall when the need to apply to the management department, otherwise violate the construction laws and regulations, the whole planning and the degree of destruction is best approved by party A and management; On the basis of the formal planning of the final licensing procedures, the calculation of materials and employment, the cost of the design implementation of the management operation and so on to propose budget and duration and construction plans and arrangements. The degree of coordination of the user side needs to be considered in the implementation plan. The implementation of the program needs to negotiate with the user to endorse the signature, and designated coordination responsible personnel designated project leader and engineering supervision personnel, responsible for planning preparation, maintenance, user side of the requirements and other aspects, put forward the timetable for each department, responsible for internal and external coordination and construction organization and management on-site construction site certification test Make the test report and make the wiring marking system.

Need to remind of the network engineering construction process requires a lot of construction materials, some of these materials must be prepared before the start of the material, and some can be in the process of preparation, the main cable, twisted-pair, sockets, information modules, servers, power supply, hubs, such as the implementation of the purchase of goods manufacturers, and determine the date of delivery, Different specifications of the plastic Groove Board, PVC fire hose, snake skin pipe, tapping screws and other wiring materials in place, if the hub is centralized power supply, then ready to wire, iron pipe and the establishment of good electrical equipment safety measures (power lines must be in accordance with the standard standards of civil architecture), the establishment of construction schedule (to leave the appropriate room, Unexpected things may happen at any time in the construction process and require immediate coordination.

Problems to be paid attention to in wiring construction

Because the design of network integrated wiring project plays a decisive role in the whole process of wiring, the design organization of the project should be cautious. On the whole, in the implementation of design should first pay attention to the standardization of standards. The implementation design of structured wiring should not only be rigorous in design, satisfy the user's requirement, but also make its cost reasonable and conform to the standard of standardization. International and domestic structural wiring has strict rules and a series of standardized standards, these standards for the structural wiring system in all aspects of a clear definition, set its design requirements and technical indicators;

Second, according to the actual situation design. First of all, the construction of the building to carry out a full investigation, to collect the building construction, decoration works and other related engineering drawings, and fully consider the user's construction investment budget requirements, application requirements and construction schedule requirements and other factors. If the building is still in the process of establishing a structured wiring scheme, it can be based on the overall layout of the building, the demand for the line to the design of the structure of the construction of the specific requirements of the structural wiring, in order to be in the construction of some wiring at the same time the Prophase project completed. If it is on the basis of the original building and the Interior decoration Project synchronized implementation of the wiring works, it must be based on the original buildings, decoration Engineering design and actual survey results of the wiring implementation design;

Finally, attention should be paid to selection and layout. The material materials and layout arrangement in the design of wiring implementation have direct influence on the construction cost. In the design, according to the needs of network construction institutions, select the right type of wiring cable and connectors, the selected wiring material grade of different to the overall programme technical indicators have a great impact. It is recommended that a manufacturer's series of accessory products be used in wiring, because wiring is a system, not a simple combination of cables and components. Besides the direct influence on the construction cost, the design of the layout arrangement also related to the network wiring is reasonable, for a multi-storey building, the installation of the entire building network backbone Switch Center network room, preferably set in the middle of the building floor, if the various floors set wiring between the best set in the middle of the floor, This design not only can shorten the vertical and horizontal backbone subsystem wiring length, save materials, reduce costs, but also reduce the unnecessary channel transmission distance, conducive to the improvement of communication quality.

In terms of the details, also need to pay attention to the construction site supervision personnel should be serious and responsible, timely treatment of the various situations appearing in the construction process, and coordinate to deal with the views of all parties; If the site construction encountered unforeseen problems, should be timely report to the engineering units, and put forward solutions for the project units on the spot to solve So as not to affect the progress of the project, the problem of poorly planned projects, should be timely and properly resolved, the new additions to the engineering units should be reflected in the construction drawings in time, to the part of the site or section to be timely inspection and acceptance, to ensure the quality of the project, it is best to work out the project schedule, but in the formulation of the project schedule, to leave room It is also necessary to consider other projects in the construction may bring about the impact of the project, to avoid the failure to finish on time, the completion of the issue, therefore, it is recommended to use supervision to assign task tables, workshop construction table.

And at the end of construction, should also pay attention to cleaning up the scene, keep the scene clean, beautiful, to the wall hole, shaft and other junction to be repaired; all the remaining materials are aggregated, and the remaining materials are placed in one place, and the quantity that can be used is registered, and the summary material: Start report, wiring Engineering drawing, construction process report, test report Use reports and acceptance reports for project acceptance.

Cabling experience five questions and answers

1. Why is it better not to have a joint in the thread tube? Where should the joint be located?

Usually the wires are not connected in the threaded tube, where conductor length is not enough to connect, the wire joints can not be in the threading tube, should be in the switch, socket, lamp box, such as wiring, otherwise, easy to cause congestion in the tube, heat dissipation, fault points difficult to find, maintenance difficulties, and may cause electrical fires.

2. Why prohibit the use of mobile bedside lamp?

Mobile Bedside lamp switch is * Soft insulated conductor and switch connection, in use if the wire and switch if separated, live line of head exposed may cause fire or electric shock accident.

3. Why must the lighting switch be threaded on the phase line?

If the lighting switch is connected to the 0 line, although the light is not light when disconnected, the phase line of the lamp holder is still connected, and people think that the light is not lit will mistakenly think that the lamp is in a state of power failure. In fact, the lighting on the various points of the ground voltage is still 220 volts of dangerous voltage, if the lights when people touch these actually charged parts, it will cause an electric shock accident, so all kinds of lighting switches or single-phase small-capacity electrical equipment switches, only string connected on the phase line, to ensure safety.

4. After the decoration, the electrical inspection should pay attention to which aspects of the problem?

All switches of the circuit to normal control of the power supply, all outlets to power the experiment, left 0 right phase, strong and weak electrical socket distance to the minimum not less than 30 cm.

5. What must be paid attention to in the embedded flea power?

Wiring should be set of PVC flame retardant pipe, and to horizontal vertical, turn to use elbow, weak electricity generally do not go to the two minimum distance of power and weak is 300MM; audio and broadband cable can not be connectors, telephone line network cable to use a special connector or distributor; When the weak electricity is disposed, the testing experiment should be carried out. Make sure the weak electricity is unblocked after sealing groove.
