In recent years, with the continuous and rapid development of the domestic air transport industry, airport logistics projects have gradually increased and the technical level has been continuously improved. The Civil Aviation Administration of China predicts that during the "Eleventh Five-Year Plan" period, air transportation in Mainland China will increase by 14%, and the investment in airport construction will reach 140 billion yuan, which undoubtedly provides a huge market space for the development of airport logistics-related fields. It is clear that by the end of 2010, about 4 trillion yuan will be required to accelerate the construction progress. In 2009, the total scale of civil aviation fixed asset investment will reach 80 billion to 100 billion yuan, an increase of more than 33% over the previous year.
The airport logistics system mainly includes three categories: airport baggage processing system, air cargo processing system, and air catering processing system. Here we mainly analyze the application of sensors in baggage and freight handling systems. The English name of the baggage handling system is BHS. It is a system for transporting and handling checked baggage for passengers in the terminal building of the civil aviation airport. It is the most important logistical position in the passenger terminal building, occupying the largest construction space, and the most systematic mechanization. In such a large and complex system, the logistics transportation system uses modern sensors to detect and process luggage and cargo, which not only improves efficiency, but also reduces the incidence of errors. Sensors are used in various types of construction and operation management of large civil aviation airport terminals, especially Plays an important role.
The following uses Bonner sensors as examples to introduce several typical applications of sensors in airport baggage handling systems:
Workstation sorting measurement:
The exit point of the airport warehouse is different from the DC point of imported goods. The goods that enter the warehouse in the morning may have to leave the warehouse in the afternoon, which is basically a "pass-through" logistics operation, so the facilities of the flat warehouse need to achieve smoother operations. The shelves usually have different size specifications, so before which shelf the goods are usually need to be classified according to the size of the goods, the measurement light curtain can help realize the automation of the classification and the measurement of the volume of the goods.
Logistics conveyor in place detection application:
Within the baggage handling system, according to the category of baggage handling: (1) Departure baggage handling system: handles checked baggage for outbound passengers (2) Inbound baggage handling system: handles checked baggage for inbound passengers, as opposed to The outbound baggage handling system is relatively simple. When the goods are shipped or received, they must be punctual, accurate, accurate, reasonable, and effective. Through the transformation and automation of the unidirectional to mixed flow of the convection line, the logistics conveyor belt system has become the link for baggage handling and transportation. The following two Zhang physical map introduces the use of Bonner's photoelectric sensor Q45 to count the processed goods to achieve automatic transportation management.
Check in baggage in place at the check-in gate:
At the beginning of the baggage entry and exit of the airport logistics system, a security check is required. At present, most airports use X-ray security inspection equipment for baggage security, and sensors are used in the device for baggage in-place inspection applications.
The above introduces the application of sensors in the three links in the airport logistics system. In fact, it is not just these three links. On the ground of the boarding bridge, the three-dimensional warehouse goods are stacked, the goods are protruded, the shelves are monitored, and the luggage is positioned on the shelf. The application of sensors can be seen everywhere in the positioning of pallet trucks and reading of cargo information. The above briefly introduces the application of Bonner sensors in the airport logistics system for readers to learn from.
