System management workstations, security verification workstations, customs verification workstations and other systems set up for the airport security work can provide more effective information services and management tools.

Fifth, the public **** broadcasting system

The public **** broadcasting system generally uses CobraNet audio transmission protocols and Ethernet-based structure, by a number of sets of digital audio matrix system *** with the same design from the airport's public **** broadcasting system should be added to the stand-alone mode and the remote backup mode function, such as the emergence of the Network paralysis, can be configured through the intelligent system to meet the needs of the airport and travelers.

Comprehensive wiring system is divided into six parts according to the structure: the building complex

Six, comprehensive wiring system

subsystems, equipment room subsystems, trunk subsystems, management area subsystems, horizontal subsystems, and work area subsystems. Trunk system should be designed according to the architecture of the network system, generally using a three-tier network structure, the equipment room is defined as three categories, one type of core room (referred to as PCR), two types of convergence room (referred to as DCR), three types of access layer room (referred to as SCR), in the three types of room laying the corresponding number of single-mode fiber optic cable, constituting the trunk part of the system. The backbone part of the airport in addition to considering the airport's own weak power information system needs, but also includes the baggage sorting system, building control system and other terminals within the various mechanical and electrical, weak power system of the backbone link connection. Horizontal system design is more complex, to carry out targeted research on specialized systems to determine the density, type and installation of the actual information points. Comprehensive wiring system is the basis of each weak electric system, and the inherent nature of the building determines that the system is part of the building structure, so on the basis of meeting the current application requirements, it is necessary to consider the changes in demand over a number of years, and to leave room for future development. Information points for important business security need to be left with spare information points, while the principle of more use and less backup is adopted for places with dense information points. For the demand, the installation method is not clear for the time being, the principle of phased design is adopted.

Seven, the airport weak power information engineering project construction and installation characteristics

1, the requirements of the preliminary design of the weak power project:

(1) Preliminary design, should be based on the actual needs of the airport and the requirements of the bidding documents, a reasonable calculation of the construction scale of the weak power project, the progress of the project, the quality standard and the project budget. Factors such as the parameters and performance of equipment and materials must be strictly in accordance with the design requirements for scientific procurement, for some new equipment, new materials, must undergo rigorous testing and research, meet the standards before being put into use in the project, must ensure the reliability of the quality of the project.

(2) The preparation of construction drawings for weak power projects must be based on the actual situation of the airport and special requirements, and should meet the requirements for materials and equipment, engineering budget, construction, installation and maintenance.

(3) weak project in order to further optimize the construction drawings design in the bidding construction unit, the bidding unit is required to deepen the design as a supplement to the construction design, deepen the design of the design documents should be reviewed by the original design unit to confirm or approve.

(4) engineering design unit, should give full consideration to the special characteristics of the airport, combined with the airport's own needs, the safety part of the key considerations, combined with the relevant provisions of the comprehensive design, for new technologies, the application of new equipment, must be rigorously designed and tested to ensure that the stability of the system operation, the design, the need to provide the construction of construction safety construction of construction workers, the safety management costs into the construction budget, to ensure that the construction of the construction of the airport is not only a good idea, but also a good idea to ensure the stability of the system operation. Costs into the construction budget to ensure the safety of the construction process.

2, project construction

This stage is the key procedures for the formation of engineering entities according to the engineering construction design, the need to spend a lot of resources over a long period of time, but does not produce direct investment benefits, weak project management focuses on safety, progress, quality, so as to reduce the investment or cost of construction. When applying for a construction license, the owner should provide information about safety construction measures for the construction project. The subcontracts should specify their respective rights and obligations in terms of production safety. The subcontracting unit shall accept the production safety management of the general contractor, and the subcontracting unit shall bear the main responsibility for any production safety accidents caused by the subcontracting unit's disobedience to the management. The general contractor and the subcontracting unit shall be jointly and severally liable for the production safety of the subcontracted works. Ultimately, the correctness of the design, the reliability of the equipment and material manufacturing, the compliance of the construction and installation, the effectiveness of the production or operation management should be comprehensively examined through the trial operation or trial production, before entering the stage of acceptance of the completion of the construction of the project of weak electricity. Procurement of weak electricity project is a work throughout the whole process of the project is one of the `core' of project management. Weak electricity project procurement work includes from the establishment of the organization, after the purchase, call, inspection, until the last batch of products through the inspection of all the work, it is the source of the foundation of the construction of the project.

3, product selection and quality inspection
