3. Building intercom systems engineering construction plans,"Weak systems engineering 1.2.2 Intelligent Building Construction Organization Plan of the content under the guidance of.Task of building intercom system construction5.3.1 The mission objectives,Understand the building intercom system construction Dell Latitude E6500 battery requirements, to master the system requirements and methods of pipeline construction; laptop battery master the system outside the host, the user's extension, power locks and other equipment installation requirements and methods to master the method of system debugging.5.3.2 task content,(1) building intercom and management systems engineering construction requirements;

(2) system pipeline construction requirements and methodologies;(3) outside the host system, the user extension, power locks and other equipment installation requirements Acer AL10A31 Accu and methodologies;(4) building management host installation and debugging;(5) system debugging and trouble shooting.5.3.3 knowledge point,A. Building intercom system construction requirements,(1) install a door host at a good level of visual height, the proposed height of 150cm (camera height).(2) non-intercom system installed in the direct sun exposure, high temperature, laptop battery Xueshuang, corrosive chemicals and too much dust.(3) all the networking cabling in general should be consistent with double shielding over five lines, metal braid shielding layer selection.

(4) The shield should be connected with all Toshiba PA3588U-1BRS Accu the shielding of the system is good, and prepare the ground handling.(5) network cabling best use of cascading manner, wiring ray tube maximize the use of iron pipes, iron pipes at both ends should be well grounded. And power cables (such as AC 220 V, lift lines, cable lines, etc.) of more than 50cm distance, in order to improve anti-interference and lightning.(6) to the stability of the system and easy maintenance,Sony VGP-BPS2C/S Battery all interconnection wiring of the thread can not be on the tube or to the flooding, the joints should be solder treated with heat-shrinkable tube package and make a waterproof moisture treatment .(7) should be considered at the entrance to the host terminal to connect the drip line.

Building intercom system is the use of embedded microprocessor technology, voice intercom technology, CCD camera and video imaging technology, intelligent systems designed for a visitor to identify the electronic control information management.Dell N950C battery Building intercom system is currently the most widely shown in Figure 5.1.2 baseband transmission, for example, the system administrator machine, outside the host, user, extension, floor platforms, networking, UPS power supply, transmission lines and other equipment composition. With system equipment is generally more flexible, according to different user requirements, the choice of different types of equipment composed of different systems.

3. Building intercom system needs analysis,(1) the need to use the occasion of the building intercom system,With the social and economic development, the increase of floating population,Dell N533P battery security has become the residents of the most basic and urgent needs of life. Needs of this social situation, the laptop battery building intercom system quickly to the rapid application and promotion, has been widely used in the residential area, office, corporate, government departments, hotels, etc..including the number of audio channels, data channels, video channels on the use of necessary equipment.It is by intercom host management, Such as the number of decoder (isolators), and video distributor, etc.;

(3) demand analysis,During the first Dell N532P battery research building intercom system planning and implementation aspects of the situation: the functionality required by the specific number of households and the total number of laptop battery systems, residential area.The @ specific number of households with the total number of: For the configuration of the building intercom system, followed by the number of households to determine the number of households within each building and each floor, use of the indoor unit the number Dell N531P battery of households can determine the district extension the total number; laptop battery according to the number of households on each unit can be determined in the unit building intercom channel,
