Weapons: Intelligent building intercom system wiring and installation methods

The intelligent building intercom system must be understood by everyone, and it is safe and convenient to communicate directly with the outdoors. The smart community's intercom system is neither digital nor so-called integrated integration work. Many engineering personnel are not very familiar with some basic concepts. There is not much understanding of the digitalization of smart building intercom systems. Basically, they all adopt the traditional bus architecture. Therefore, the information on the design and construction of some smart building intercoms is not very complete. The author will start with this section.

A host of intelligent building intercom system design features <br> <br> in intelligent building intercom system components on the part of the content and construction, door phone device is installed in the security door at the entrance of the building. It includes an operation panel, a bottom box, a camera, and a voice signal and control section. In the construction project, there is an anchoring of the bottom box, the assembly of the panel, and the connection of the circuit. The most important tasks are the adjustment of the image and the correction of the light difference between day and night.

In addition, because of the need to cooperate with the residential structure, it may be necessary to cooperate with civil engineering projects in the application. Its purpose is mainly to avoid the bottom box extrusion deformation and the perfect panel fixing. The project installed on the door machine also includes a sound receiving and sending part. In the case of application, attention should be paid to the sound pressure and the height of the horn collector installed, in order to suit the average height of the average user.

In the video part of the door machine, due to the limited depth of field of most installation points, most of the cameras adopt the board type, so the performance of the camera is slightly worse than that of the general surveillance camera, and the quality and resolution are not High, and most of them lack the performance of backlight correction, so there are some entrance door opportunities to install infrared light or white light to strengthen the image, these conditions require that the intercom door machine in the installation of some special engineering adjustment projects must Execution, this must be paid attention to in the intelligent building intercom system.

Second, intelligent building intercom transmission and networking cabling technology

As smart building intercom systems are gradually moving towards digital applications, many engineering companies must integrate the access control systems of various brands into the door-to-door and system cabling integration. Therefore, the networking of the system must take into account the interconnection of the intercom and the access control system. Line layout and signal transmission.

The design of the network integrated cabling project has a decisive influence on the process of wiring the intelligent building intercom system, and should be carried out with caution in construction design and installation projects. Usually, after the construction planning of the intelligent building intercom system is completed, the next step is the installation and implementation of the project. The most important task before construction is the project preparation work. These tasks and precautions include the following.

1. Grasp and fully understand the wiring construction drawings, determine the location of the wiring needs to consider such as beauty and concealment, the damage to the building must be reduced to a minimum, in the cloth to avoid power lines and other communication lines to avoid interference and crosstalk Situation, at the same time must have the necessary protective measures to the cable, at the same time must estimate the feasibility before the installation and install the wiring, especially in the project such as going through the wall and beam column, etc.), after being feasible to pay, etc. , Construction personnel, supervisors and supervisors perform.

2. Carefully calculate material requirements In the final worksheet, it is necessary to do a good job of calculating materials and employment, and comprehensively consider the costs of management operations during design and implementation, and propose budgets, durations, and construction plans and arrangements. The degree of cooperation of the user needs to be considered in the implementation plan. The implementation plan needs to negotiate the approval signature with the user and specify the coordinating responsible person to designate the person in charge of the project and the project supervision personnel to be responsible for planning the preparation of materials, preparation of the work, and the user's request for cooperation.

3. Intelligent building intercom network construction requires many construction materials in the construction process. Some of these materials must be prepared before the start of construction. Some can be stocked during the start-up process. These materials mainly include optical cables, UTP twisted pairs, and RJ sockets. , signal control modules, servers, voltage regulators, HUB hubs, etc., and determine the date of delivery, different specifications of PVC fire protection pipe, winding pipe, screws and other materials in place, will do a good job construction equipment and equipment safety measures, Formulate construction schedule.

4. When planning and designing the intercom system, it is first necessary to pay attention to the specification standard.

The design of the wiring must be done to meet the needs of the users, and at the same time, the construction cost must be met. Strict standards have clear rules for the structured cabling system to achieve engineering requirements and technical pointers.

5. The smart building intercom system must be implemented according to the actual situation.

The layout of the layout of the design in addition to the direct impact on the construction costs, but also related to whether the network cabling is reasonable, for a multi-storey building, the installation of the entire building network backbone switch information center network room, preferably installed in the building In the middle floor, if the wiring closet is set on each floor, it is better to set it on the middle section of the floor. This design can not only shorten the wiring length of vertical and horizontal trunk subsystems, save materials, reduce costs, but also reduce unnecessary channel transmission. Distance and material waste.

6. There are also all kinds of situations that need to be dealt with in a timely manner in the construction process to coordinate the opinions of all parties; if unforeseen problems are encountered during construction, they should report to the engineering unit Yuanyuan in time and propose solutions for the Yuan Yuan of the engineering unit. Study and solve so as not to affect the progress of the project.

Third, the plan details the installation of intelligent building intercom equipment <br> <br> intelligent building intercom system equipment installation, the installation must take into account the various problems that may occur, a large range of these specific issues, there are many types in the construction must One by one to understand their details, first look at the host part (including the door host, wall door host, indoor host host) should pay attention to some of the following points:

1. Do not expose the equipment to wind and rain when it is absolutely necessary. If it cannot be avoided, please add a rain cover;

2. The door machine should not face the camera lens to the intersection of direct sunlight or light;

3. Use fill-up light measures to try to keep the background light in front of the camera of the door camera in average uniform;

4. Avoid the motor of the electric reel door or do not install near the strong magnetic field; the line wiring should consider the guiding dripping line at the entrance of the host;

5. Color cameras should consider the need for visible light compensation at night;

6. Do not install in an outdoor environment where the ambient noise is greater than 70dB. The indoor unit should not face the display with strong light. The LCD color display should pay attention to light reflection and monitor the angle. Do not install in high-temperature heating lines, air conditioning, low temperatures, excessive dust or serious pollution.
