The airport, as a window to the city, is often seen as a microcosm of the economic boom in the region. Among them, the application of advanced communication technology means has been paid more and more attention to the role of airport in improving production efficiency and safety.
1. Airport communication needs
With the increasing demand for air transport capacity, most of the airport's ground resources are in a state of tension to cope with rising passenger and freight demand, and flight delays have become an important factor in reducing passenger travel satisfaction. In general, airport communication mainly includes point-to-point voice communication, voice communication between multiple points, data transmission and image and video transmission under higher requirements. The cross-use of these communication methods enables efficient command and dispatch, which can meet the demanding requirements of airport communication, so as to better ensure the on-time rate of flights and the efficiency of airport operations.
Considering the savings in valuable time, the rapid sharing of information is very important. The on-time rate of the airport industry is an important assessment target. The key factors affecting are paper-based information and manual delivery. For example, the baggage sheet is generated after the check-in is stopped, usually 30 minutes. In this short period of time, the relevant baggage transportation is completed and sorted. Typically, only 7 to 8 minutes are used to manually pass relevant documents to the flight. For some flights with relatively long stops, this information transfer process may cause excessive delays. Baggage sorting is also an important factor. If a passenger stops boarding, his baggage needs to be picked up and shipped back. Usually only five or six minutes can be used to convey relevant passenger and baggage information. So far, there is not enough communication network to ensure the rapid transmission of the above information. Considering the mobile nature of the airport's many people, it is necessary to use a wireless communication network at the airport as a support. Moreover, the system requires seamless coverage within the airport, such as check-in counters, waiting halls, baggage sorting areas, airport runways, maintenance work areas, ground crew waiting areas, etc., to ensure that information is in each Accurate sharing before the relevant departments of the business, providing communication links to make it work seamlessly and improve work efficiency.
From the perspective of communication methods, it is necessary to provide a synchronous communication method of data and voice. Many airports currently use walkie-talkies as the main communication device. This method used to play an important role in airport dispatch communication, but its existence is very important: all information is instantaneously transmitted, and information content cannot be recorded and copied. Information delivery results are not identifiable and tracked. The working environment of the airport is noisy, and the ground personnel accept and transmit the work order information in such an environment, which is very easy to make mistakes in the process. Equally important is the fact that all processes are still undocumentable, which can affect the crux of finding problems in later backtracking. The above inefficient scheduling communication process is the direct cause of flight delays.
From the perspective of delivering content efficiency, it is necessary to provide multimedia information transmission capabilities. Whether it is voice or text, the ability to express the situation on the opposite end of the communication is far less than the picture or video. Multimedia communication imposes high requirements on the transmission bandwidth of wireless systems.
2. Huawei wireless communication solution
Based on the above-mentioned demand for broadband wireless communication with simultaneous interpretation, Huawei has launched the eWBBLTE airport communication solution. Due to the adoption of LTE technology, the scheme has extremely high spectral efficiency. With 20MHz spectrum bandwidth and 2&TImes; 2 MIMO configuration, the downlink theoretical peak rate can reach 100Mbps, and the uplink theoretical peak rate can reach 50Mbps. Based on LTE flat architecture, Huawei ground The empty wireless broadband system has good delay performance. The user plane delay is up to 5ms, and the control plane delay is up to 100ms. At the same time, in order to make full use of spectrum resources, the Huawei eWBB LTE solution specifically designed the asymmetric characteristics of the uplink and downlink system bandwidth, such as supporting uplink 5MHz and downlink. A 10 MHz cell, or a system bandwidth configuration of 10 MHz upstream and 5 MHz downstream. The solution provides a wide range of featured applications for the aviation industry, such as video surveillance and passenger information sharing. Through timely delivery of shared information, ground space personnel can be promoted to work together. In the event of an emergency, video surveillance can be used to detect and prevent the expansion of the situation in time. It can also be used as the main vouchers after the event to carry out the playback and backtracking of the scene. These are all very important to improve the safety of aviation law operations. help.
3. Application of Huawei wireless communication solution
3.1 New scheduling mode: PTT, simultaneous use of voice and command data
The best way to reduce the misunderstanding of voice communications and improve the inefficiency of paper-based processes, PTT and solutions based on simultaneous use of voice data. In the dispatch center, all tasks have been scheduled based on flight dynamics, and the dispatch system will alert the dispatcher to the tasks assigned by the PTT in a timely manner. At the same time, the workflow starts with PTT. Through the Gantt chart of the workflow, the dispatcher can grasp all the mission status and the status of the ground crew. Task assignments based on flight times can be issued with a simple command code to ensure instant communication between all involved personnel. Through the comprehensive utilization of various communication methods, the correct person is guaranteed to reach the designated place at the right time. If there is a mistake in the process, the dispatch system will issue a warning to the dispatcher to redistribute, thus reducing the error rate.
3.2 task automatic allocation
The baggage slip can be automatically distributed in the form of text by the dispatch system using the LTE network to replace the manual transfer. When the flight generates a baggage slip, it will pass the information directly to the flight in the shortest amount of time. This process takes only a few seconds. With a wireless printer installed on the baggage cart, the baggage order can be printed and signed on site. The remaining time can be reserved for on-site adjustment of baggage and cargo, thus effectively ensuring the on-time rate of the flight.
3.3 Emergency response
An important cause of flight delays is the weather, which will directly or indirectly affect a large number of flight itineraries, seriously affect passenger sentiment, increase airport operating costs, and as the flow of passengers increases, the pressure on the airport also increases dramatically. In this case, how to deal with, how to obtain first-hand information, using video and screen command and dispatch, is particularly important. Through video technology, we ensure the most timely access to on-site information and provide the most effective decision-making basis.
3.4 Vehicle dispatch management
Each flight has different types of service vehicles, such as fuel trucks, shuttle buses, road wreckers, etc., reasonable scheduling and monitoring of vehicle operations are very important to ensure the efficiency and safety of airport operations. For example, the arrangement of a shuttle bus is a location-based service that needs to be arranged according to the location of the current locomotive and the time and destination it needs to use. At the same time, different airport areas have different levels of security, and only authorized vehicles can enter areas with appropriate levels of security. The location information of the vehicle will be transmitted back to the center without interruption. Once a vehicle enters the area where it is prohibited from entering, the sound and light alarm will be activated at the same time, and the driver and dispatcher will be prompted. Flexible vehicle management ensures timely and reasonable adjustments when scheduled schedules change.
3.5 Mobile video surveillance and image transmission
In the airport area, it is impossible to monitor every corner for 24 hours, so it is necessary to clarify which corners are blind to airport monitoring and how to narrow these blind spots. Once you need to know the situation of these locations, you can solve it through wireless video surveillance, and carry the above video through the LTE network. Through the mobile video terminal, the situation on the spot can be timely fed back to the dispatch center. Thereby supporting remote remote command and handling emergency situations.
