Airport wireless broadband multimedia cluster scheduling system scheme

Airport wireless broadband multimedia cluster scheduling system scheme

survey:
In 2011, the number of civil airports in China reached 185. At the same time, there are nearly 300 military airports in China. Every year, dozens of airports have completed the reconstruction and expansion projects of Airport Station area, including new runway, new terminal, extended apron, extended runway, runway extension and navigation lighting reconstruction.
According to the prediction of relevant government departments, by 2020, the National Airport cargo throughput and passenger throughput will maintain an annual growth rate of 15% and 11.4% respectively. There will be 13 airports with an annual passenger throughput of more than 30 million people, 6 airports with an annual passenger throughput of 20-30 million people and 10 airports with an annual passenger throughput of 10-20 million people.
The current situation of domestic airports in the application of information technology is a typical cooperative operation support service-oriented unit, which is now mainly solved by business software support system, cable telephone scheduling, digital cluster, analog cluster, radio, radar and other ways.
Most of the digital clusters of the airport are built by the air traffic control bureau, which adopts the second generation of digital clusters, and then rent them to the airport and airlines at a price ranging from 600 to 900 yuan per month. The system is stable, reliable and mature, but at the same time, it also has the defects of expensive price, tense frequency resources, and can only solve narrow-band voice problems. About 70% of the remaining airports are built by the airport's own analog or digital trunking network, which is then operated by the airport and leased to various airlines.


Now the main problems of the airport are:
1. The cost of digital trunking is too high (and broadband transmission cannot be solved)
2. The examination and approval of 800m cluster frequency is very strict, which brings a high threshold to the user department
3. The reliability of public wireless broadband is not enough, congestion often occurs, and the monthly rent is quite expensive
4. Information source can only be collected by manual input, resulting in errors in the information collection of the whole information system
5. Increased the workload of the staff, and did not really improve the efficiency
6. In the collaborative operation of pure voice between analog cluster and digital cluster, the staff often perform tasks with paper and pen, so the reliability and uncertainty are very low
7. The security of simulation cluster is not good, it is easy to be disturbed and eavesdropped.


Scheme introduction:
Airport wireless broadband multimedia cluster system provides the airport with digital cluster, voice, dispatching, broadband data, video, image, positioning information, operation information, personnel status, vehicle (air food, ferry car, luggage car, aviation oil, tractor, ground service, etc.) operation and path navigation information, as well as airport emergency command and support system. The system has been applied to capital airport, Hongqiao, Pudong, Shenzhen airport and so on.
The network structure topology of the new generation wireless broadband multi service cluster communication and information integration system is shown in the figure below:

The main components of wireless broadband network and service system include simphone multi service wireless handheld terminal, vehicle and portable intelligent data terminal, wireless broadband multimedia cluster system base station, wireless broadband multimedia cluster system service system, push service information (push Message) server, real-time video scheduling server, business system server and other key equipment.
Multi service handheld terminal equipment: provide wireless broadband multimedia trunking system, GSM / GPRS, WiFi 802.11b/g multiple network access modes, wireless broadband multimedia trunking system trunking voice communication, wireless broadband multimedia trunking system / GSM voice phone communication, wireless broadband multimedia trunking system / GPRS / WiFi data service application, as well as multimedia audio and video real-time transmission and adjustment Degree of business, push business information transfer and other professional business capabilities;
Voice cluster dispatcher: provide easy to manage voice cluster dispatching business control, realize voice cluster dispatching capabilities such as single call, group call, broadcast, etc.; the push data service server specially designed by Zhilian Tiandi, introduce BlackBerry business into the operation management of the airport, seamlessly connect with the operation command system of infoair airport, and integrate the application.
Live video dispatch server: the wireless broadband real-time video dispatch server designed by Zhilian Tiandi, supports ad-hoc and managed mode real-time video dispatch services, and realizes real-time video dispatch services between handheld wireless terminals and between wireless terminals and wired networks.
Service support system: the service support system integrates the business and service of the original infoair system with the wireless broadband network of the wireless broadband multimedia cluster system, and integrates seamlessly.
