Program overview
Airport real-time vehicle management system optimizes vehicle operation schedule and improves passenger ground transportation efficiency
Facing problem
Like most airports in the world, Dusseldorf International Airport has a passenger flow of several million people each year. Unlike other airports, Dusseldorf Airport’s 74 aprons are spread over an area of 723 square kilometers, with only 50 vehicles. Buses operate within the airport, and the newly-built railway station is 3.5 kilometers away. There is a lot of time pressure to ensure the normal operation of vehicles in the airport, and the provision of reliable and fast services is faced with arduous challenges. Because the airport is full of noise, the effect of transmitting commands to the driver through wireless phones is very poor, and Dusseldorf Airport needs a better way of communication.
In most commercial fields, time is a very critical factor, and it is particularly important for operating an international airport. As the profit margin of flights is getting lower and lower, the pressure naturally shifts to requiring shorter and shorter flight operation cycles, which means that passengers must be transported to or off the apron as quickly as possible.
However, the above tasks cannot be undertaken by machines, and the mobility of people in the airport is very high, requiring drivers to be able to respond quickly to new situations and changes in unplanned driving routes.
Before adopting DELogic’s solution, Dusseldorf International Airport relied on wireless phones to coordinate the driver’s operations in a very harsh and noisy environment. Due to take-off and landing noise and other continuous background noise, it is difficult for airports to improve the efficiency of operation and maintenance. Dusseldorf Airport urgently needs a system that can send information to the driver in a clear, fast and easy-to-understand form. The system can directly send dispatch instructions, take-off and landing information through the host computer in the form of distribution verification and verification, and use it for vehicles. Can be optimized.
solution
Georges, Head of Communication Systems Department at Dusseldorf International Airport, explained the reasons for choosing the logical wireless solution:
“At the suggestion of our wireless partner-AEG Mobile Communications -, we contacted Delogic. The key factors for us to choose their solution were the system’s rapid response time of less than 1 second and the overall safety and security of the system. Reliability is confirmed by visiting the website of Logic’s customer.”
For the above reasons, considering that the signal strength of the narrowband system rather than the data transmission speed is suitable for airport applications, Dusseldorf International Airport tends to choose a logical narrowband system. In the same size range of the airport, if you choose a broadband solution, you need 50 An AP (Access Point), while choosing a narrowband solution, is in sharp contrast to this.
Georgens said: “Insufficient system capacity is not a problem. Logical narrowband and broadband solutions can coexist in the same system. For applications that require more data for baggage processing, broadband solutions can be used if necessary in the future, because both These solutions can exist at the same time.”
It is very important to keep in touch with the driver at all times. Therefore, the new wireless data transmission system adopts a completely redundant configuration. In any place in the airport, the on-board terminal can be identified by at least two wireless gateways in the system. The location of the mobile crane and construction work is very important.
Customer benefits
In contrast to the original wireless telephone system, DELogic’s solution can transmit all flight-related information to the dispatcher, including information such as plane landing, take-off, number of passengers, take-off area, and the number of buses required. This information comes directly from Host system.
Now, what the manager has to do is to assign jobs to them when there are free buses in the system. In fact, the system knows which car is refueling, which car is in the garage or which car is stopped according to the driver’s operating conditions, and the system can also delete the car from the activity registration table, making the assignment of tasks clearer. What the driver has to do now is to confirm the job assignment-related information and notifications displayed on the terminal screen.
Since the current status and movement of all vehicles are recorded in the host system in real time, the control of the vehicles going to and from the airport has changed significantly. The right number of vehicles appear at the right place at the right time, and passengers board or leave the aircraft via the best route. Depending on the arrival and departure of the aircraft, it is possible to use this solution to simultaneously arrange vehicle refueling, parking and rest, which is very important at peak times.
Due to the extremely successful implementation of DELogic’s solution, the airport is planning to integrate new functions into the existing wireless network, including the management and scheduling of fuel trucks, aircraft tractors, luggage transport trucks and catering trucks.
In the future, many new services must be integrated into the existing system. The logical broadband network can coexist with the narrowband solution, which brings many development opportunities for the airport.
