First, industry background
Sanya Phoenix International Airport is located in Fenghuang Village, Tianya District, Sanya City, Hainan Province, China, about 11 kilometers east of Sanya city center. It is a 4E civil transport international airport and a domestic trunk airport in China。Sanya Phoenix International Airport has two terminals with a total of 10.50,000 square meters, runway length of 3,400 meters, parking apron 6.160,000 square meters, can meet the annual passenger throughput of 20 to 25 million passengers。
Second, demand analysis
With the continuous improvement of airport ground service information process, service efficiency, flexible scheduling and other requirements,In order to better achieve digital management,The quality of airport services will be further improved,Ensure flight punctuality rate and safety rate,Improve work efficiency,Reduce operating costs,It has become an urgent problem to be solved by the ground service units of airports and airlines。Therefore, it is urgent to establish a set of advanced and practical digital communication system as a communication tool for airport daily work:
1, to solve the problem of weak signal in the building, logistics center, international cargo station building, unable to communicate;
2, single call, group call, full call;
3. Realize unified dispatch and personnel information management in the command center。
Third, the solution
According to the communication command requirements of Hainan Phoenix Airport, a set of Beifeng SDC intelligent IP interconnection system (BF-8100 system) was built:
1. The command center builds a set of system server, which combines B/S architecture and all-IP technology. The all-IP exchange mode has the characteristics of stable communication, clear sound quality and good confidentiality, so as to ensure efficient and accurate communication of personnel information in the airport。
2. The cabinet is equipped with two sets of repeater, combined branch, duplexer, and near-end unit of the optical fiber repeater. The repeater connects to the system server through network cables。The repeater adopts TDMA dual time slot, static and dynamic encryption, IP interconnection and other technologies, which can be continuously transmitted under 50W power, and can also adjust the transmission power at 25-50W。Meet the growing scheduling and communication needs of airlines and the indoor and outdoor communication needs of the growing Air city area。
3, the whole network recording system based on IP switching, can achieve single call, group call, group call, dynamic group call, positioning, recording and other functions。No call is missed, the system has good scalability and high accuracy, and can accurately record every call triggered by users on the network。The recording system also supports remote query and account management. Once data needs to be retrieved, maintenance engineers can retrieve recording data on demand without traveling long distances。
4, through the fusion gateway can realize the guarantee of cross-system, cross-network unified command and dispatch communication, for the construction of the building, logistics center, international cargo station indoor distribution design, through the coupler, power divider, optical fiber repeater remote machine with indoor antenna to reach each floor, to achieve full coverage of the communication network。
5, the client and command agent dispatching desk can command and dispatch terminals in the system, with call priority level, to ensure that staff can obtain the call channel in emergency time, and realize visual scheduling, command delivery and voice/information scheduling under GIS plane map and satellite map。
