Airport, as a city window, its modern and efficient operation is often seen as a minority of economic vitality in the region. Among them, the application of advanced communication techniques, the role of airport operations in improving production efficiency and security, and is increasingly attacked.
1. The demand for airport communication
With the increase in air transportation capacity, most airports are in a state of tight, to address continuously rising passenger transport and freight demand, flight delays have become an important factor in reducing passenger travel satisfaction. From the whole, airport communications, mainly including point-to-point voice communication, multi-point voice communication, data transfer, and higher demands below image and video delivery. The cross-use of these communication methods can achieve efficient command scheduling, which can meet the demanding requirements of airport communications, enabling better guaranteed flight detection rates and efficiency of airport operations.
Considering the valuable time, the rapid sharing of information is very important. The flight alignment rate of the airport industry is an important assessment goal. The key factor affects is based on paper information and manual delivery. For example, the luggage single is generated after the Check IN is stopped, usually 30 minutes, and complete the related baggage transportation, sorting in this short period of time. Typically, only 7 to 8 minutes are used in manual delivery of relevant documents to flights. For some flights with relatively far, this information transfer process may cause too long time delay. Baggage sorting is also an important factor. If the passenger stops the boarding, his luggage needs to be passed back, usually only five or six minutes can be used to pass related passengers and baggage information. So far, there is not enough support network to ensure fast delivery of the above information. Taking into account the office characteristics of many people moving in the airport, it is necessary to use wireless communication networks at the airport as support. Moreover, the system needs to be seamless coverage within the range of the airport, such as check-in counters, Hou machine halls, luggage sorting areas, airport runways, maintenance workspaces, land-stricken person waiting zone, etc., to ensure information in each Accurate sharing before business related departments, providing communication links, seamlessly cooperating, improving work efficiency.
From a communication method, you need to provide synchronous communication methods for data and speech. Many airports currently use walkie-talkie as primary communication equipment, this approach has played an important role in the communication of airport scheduling, but there are some important defects: all information is instantly completed voice pass, and the information content cannot be recorded and copied. Information transfer results are not confirmed and tracked. The working environment of the airport is more noisy, and the ground personnel accept and pass the work command information in such an environment. It is easy to make mistakes in this process. The same important issues are there, all the processes are still not recorded, which affects the problem of finding the problem when you are backcrown. The above inefficient scheduling communication process is the direct cause of flight delays.
From the perspective of passing content, information transfer capabilities are required to provide multimedia. Whether it is speech or text, the expression ability of the communication peer-to-end field is far less than picture or video. Multimedia communication has highly requested a high demand for transmission bandwidth of wireless systems.
2. Huawei wireless communication solution
Based on the demand for broadband wireless communication of the above-mentioned columns, Huawei company launches EWBBLTE airport communication solution. Due to the use of LTE technology, the program has extremely high spectrum efficiency, using 20MHz spectrum bandwidth, 22 MIMO configuration, downlink theory peak rate up to 100Mbps, uplink theory peak rate can reach 50Mbps. Based on LTE flattening architecture, Huawei Airline Wireless Broadband systems have good delay. The user's face is delayed to "5MS, the control surface is delayed" 100ms. At the same time, in order to make full use of spectrum resources, Huawei EWBB LTE solution specializes in a non-symmetrical feature of upstream system bandwidth, such as supporting upstream 5MHz and downlink 10MHz cells, or system bandwidth configurations of 10MHz and downstream 5MHz. The solution provides a variety of special features for the aviation industry, such as video surveillance, passenger information sharing. Promote the collaborative work of the ground air person by timely delivery of shared information. When you encounter an emergency, you can use video surveillance, timely discovery, and prevention of the extension, you can also use the main credentials afterwards, the playback and backtram of the field situation, these are a large safety help.
3. Application of Huawei Wireless Communication Solutions
3.1 New scheduling mode: PTT, voice and command data simultaneously
In lowering voice communication, enhances the low-efficiency aspects of paper-based processes, the best ways of PTT and speech data simultaneously using voice data. In the scheduling center, all tasks have been scheduled to be scheduled according to flight dynamic information, and the scheduling system will remind the dispatcher to promptly pass the PTT assigned task. At the same time, the workflow starts with the PTT. Through the workflow of the Gantt chart, the dispatcher can master all task status and the status of the ground personnel. The task allocation based on the flight time can be issued by a simple command code to ensure that the instant messaging between all people involved. By comprehensive utilization of a variety of communication methods, it is ensured that the correct person reaches the designated location in the correct time. If there is a mistake in the process, the scheduling system issues a warning to request the dispatcher to reallocate, thereby reducing the error rate.
3.2 Task Automatic Assignment
The luggage single can use the LTE network to carry out automatic assignments in the form of the text using the LTE network to replace the past manual transmission. When the flight generates the luggage order, the information will be delivered directly to the flight in the shortest possible time, and this process only takes a few seconds. With wireless printers installed on the luggage car, the luggage list can be printed and signed on site. The remaining time can be left to the site to adjust the baggage and cargo to effectively ensure the flight's number of points.
3.3 Emergency response
An important reason for causing flight delays is the weather, which will directly or indirectly affect a large number of flight trips, seriously affect passenger emotions, increase airport operating costs, and increase the pressure in the airport, the pressure is also sharply increased. In this case, how to deal with how to obtain the first hand, use the command scheduling of the video and pictures, it is especially important. Through video technology, ensure the most timely acquisition site, provide the most effective decision basis.
3.4 Vehicle Scheduling Management
Each flight has different types of service vehicles, such as fuel cars, shutdown vehicles, road wreckers, etc. For example, for the arrangement of the shuttle car is a location-based business, and it is necessary to arrange according to the location of the current locomotive and the time and destination required for use. At the same time, different airport areas have different safety grades, and only authorized vehicles can enter areas with respective safety levels. The location information of the vehicle is uninterrupted, once the vehicle enters the area where it is forbidden, the sound alarm will start while prompting the driver and dispatcher. Flexible vehicle management ensures timely and reasonable adjustments in time when the scheduled plan changes.
3.5 Mobile video surveillance and image transfer
In the airport range, it is impossible to do 24 hours of monitoring every corner, so it needs to be clear which corners are blindly monitored by airport, and how to shrink these blind areas. Once you need to understand these locations, you can be solved by wireless video surveillance, and the above video is carried by the LTE network. By moving the video terminal, the situation in the field can feed back the dispatch center in time. Thus, remote remote control, handling emergency situations.
