A typical intelligent building network system configuration


, Using the following steps to ensure network security; firewall: from the Inter-net's security threats can not be overlooked. In order to prevent network hackers. Should be used firewall technology; set up a dual host: host to connect using the two-business networks and Inter-net. Prohibition on dual host routing function, isolation associated with it the question of the traffic network. It is associated with each network can be executed by the web application it provides. Using star schema, using a virtual network. Servers with dual backup mode, the disk array supports hot-swap applications using client / server model. On the server side of applications, databases, and running processes are providing security; on the client side, in addition to the password required to enter the station outside. The application of a unified registration system needs to complete the process of application through a special application to complete user registration scrutiny, while maintaining the user dictionary of properties, including: accounts, passwords, privileges, etc. Structured Cabling One of the goals of the network construction is to build intelligence headquarters building. The so-called intelligent building system integration method is used, the computer technology, communication technology,Beats By Dre Studio, construction technology, combine, through the automatic monitoring equipment, information resources management and the optimal combination of information and construction to meet the needs of users . It includes the following sections: First, the building automation system: including power supply and management, lighting control and management, environmental control and management, fire alarm and management, security monitoring, radio systems, management service subsystems. Second, the office automation system: technology and equipment for the computer technology and related equipment, including word processing, data handling technology, including computer hardware, sound, image input and word processing equipment and other hardware. Third, the communications automation systems: communication and networking technologies, including intelligent space electronics and communication engineering information 98.7 Gold Series letter equipment telephone, fax, data,herve leger toronto, facsimile equipment, network equipment, e-mail equipment, electronic equipment, according to the business meeting building layout, the distribution functions of the structured cabling system design are as follows: 1. Administrative buildings, research buildings and other 3 buildings as the center, between buildings using fiber optic cable, constituted an enterprise backbone. There are buildings in the main building, the first layer or level of each sector to form a wiring unit. Building using unshielded twisted pair wiring as a transmission medium. 2. The department set up one hole or two holes as needed RJ-45 jack. 3. The main floor with a wiring device. Taking into account more access nodes, each with a layer of each patch panel. Network management center set up in the Administration Building 4, the network construction should be aware of the following best outdoor cable buried in the ground For overhead,Salvatore Ferragamo outlet, the height should be more than 4m, and be careful not to ride in the trunk or other buildings, but not with power power cord overlap. If cable length exceeds the effective transmission distance, repeaters must be used. Cable laying to natural straight, not twisted,herve leger sale, knotted. Thick of the corner radius should be greater than 3O cm, thin cable of the corner radius should be greater than 20 cm. Hub not on the floor or fixed to the table panel, should be installed at a suitable height from the ground, or wall fixed. Test to ensure the quality of structured cabling projects in the construction process, appropriate testing should be carried out to the full test report issued by the user. The report will serve as an important condition for project acceptance. Wiring test is generally divided into three steps: First, the step-wise way to install the PDS system installation and testing. Mainly use the dedicated wiring test instruments for the installation of the various subsystems PDS after the open, short circuit, polarity, such as whether there is crosstalk performance testing, and testing of external electromagnetic interference and grounding problems. Second, the PDS system has been installed system testing of the PDS system has been installed, use special equipment for each subsystem cable attenuation, near-end crosstalk, connection length, DC loop resistance testing and other indicators. Third, after the opening of the PDS system to use the test after the installation and system testing after passing the test system for further data transfer rate of the indicators can be used after the opening of the PDS system on the network termination and terminal equipment, the use of rate-related test software for testing. After completion of the transfer, the construction units should be before the project is completed, the completion of the project technical information in triplicate to the user, including: installation of quality, project description, equipment, equipment schedule, completion of drawings, test reports and other records. Users not only receive the paper should pay attention to information, should pay attention to keep the computer receives the electronic information in order to Computer Management. The network structure is shown below Figure intelligent building network system diagram,
