Technical Field
The invention relates to the field of airport luggage sorting systems, in particular to an airport luggage emergency sorting method and system based on an RFID technology.
Background
Currently, airport baggage handling system sorting data is derived from flight data from airport information integration systems and departure system baggage source message data. The unified information integration system of the airport sends the flight basic data and the baggage sorting chute data used by each flight to the sorting information system before the daily flight execution. After the luggage is handled, luggage source data such as luggage bar codes, dates, flights corresponding to the bar codes, flight execution dates and the like can be sent to a luggage sorting information system through the departure system in real time, the sorting system compares the luggage data which is identified in the system according to the luggage data received in real time, calculates luggage attributive flights and destination sorting chutes, sends sorting paths to be executed by the luggage to the electric control system, and sorts the luggage to the destination chutes.
In this business process, the airport baggage sortation function is highly dependent on the departure system baggage source message data generated during the baggage check-in process and sent to the sortation system in real time. Because the existing airport luggage sorting system mostly uses the recognition scheme of 'one-dimensional bar code + laser bar code recognizer', the 10-bit label number of the luggage can only be automatically recognized in the luggage conveying and sorting process. If the data of the departure system cannot be timely sent to the luggage sorting information system, the sorting system cannot calculate the subsequent luggage sorting chutes, and a major fault that the whole automatic sorting function of the luggage system fails is caused. Will seriously affect airport operations and baggage service quality. If the data of the information integration system is not sent to the baggage sorting information system in time, the data receiving and sending of the changed flights and flight sorting chutes on the same day are affected, and the subsequently executed flights and baggage may form a large-area mis-sorting or abnormal sorting phenomenon, which causes the abnormality of airport operation and baggage service.
Therefore, under the current technical conditions, when data communication between the baggage sorting information system and the airport departure system or the information integration system is interrupted, great hidden danger that the automatic baggage sorting function is affected to different degrees or even the automatic baggage sorting function is wholly failed is caused, and a new technology-based baggage sorting emergency method is urgently needed to be designed through technology upgrading or optimization and reconstruction so as to maintain the automatic baggage sorting function to be normal and orderly under the emergency situation of data communication interruption between the baggage sorting information system and the airport departure system or the information integration system.
