Description

Technical Field

[0001] The present invention relates to the field of airport cargo terminal automation technology, and in particular to an unmanned processing method and system for an airport smart cargo terminal. Background Art

[0002] With the rapid development of the global aviation logistics industry, airport cargo terminals, as key nodes in logistics transportation, are crucial to the smooth operation of the overall logistics chain in terms of processing efficiency and service quality. However, the traditional airport cargo terminal processing method is highly dependent on manual operation, which is not only inefficient, but also prone to errors and difficult to cope with the growing logistics demand. Especially during peak hours, manual operation is prone to cargo backlogs, delays and damage, which seriously affects logistics efficiency and customer satisfaction.

[0003] In recent years, with the rapid development of technologies such as artificial intelligence, the Internet of Things, and big data, smart logistics has become an important development direction for the logistics industry. Smart logistics integrates advanced information technology to achieve intelligent, automated, and efficient logistics processes, effectively improving logistics efficiency and service quality. As an important part of smart logistics, the research and application of unmanned processing methods for airport smart cargo terminals have important practical significance and broad application prospects.

[0004] At present, the research on airport smart cargo terminals at home and abroad mainly focuses on the following aspects:

[0005] 1) Automated sorting and transmission system: By introducing automated sorting equipment and transmission systems, the goods can be quickly and accurately sorted and transmitted, improving the handling efficiency of the cargo station. For example, the I CS automated transmission system can achieve high-speed transmission and final sorting, significantly improving logistics efficiency;

[0006] 2) Intelligent robots and unmanned vehicles: Use AGV (automatic guided vehicles), unmanned forklifts and other intelligent robot equipment to achieve automatic handling and storage of goods, reduce manual intervention, and improve operation accuracy and safety. Intelligent vehicles such as ULD-AGV can accurately deliver goods to designated locations, greatly improving the automation level of logistics operations;

[0007] 3) Intelligent information collection and identification technology: Through intelligent information collection and identification technologies such as DWS (Dimension Weight Scanning) system, RFID (Radio Frequency Identification), barcode scanning, etc., automatic five-sided code reading, automatic weighing and volume measurement of goods can be realized, improving the accuracy and efficiency of information collection;

[0008] 4) Unmanned security inspection and tallying system: Utilize advanced security inspection equipment and tallying system to realize unmanned security inspection and tallying of goods, reduce manual intervention, and improve security inspection efficiency and accuracy. At the same time, by introducing intelligent dispatching system, autonomous dispatching and collaborative operation of unmanned vehicles can be realized, further improving logistics efficiency;

[0009] 5) Smart management platform: By building a smart management platform, we can achieve real-time monitoring, data analysis and management optimization of the entire process of the airport cargo terminal, and improve the overall operational efficiency and management level of the cargo terminal. The smart management platform can achieve seamless connection with logistics companies, order systems and data analysis systems, and provide logistics companies with real-time distribution statistics and business optimization suggestions.

[0010] However, despite many research results and technical applications, the unmanned processing methods of airport smart cargo terminals still face many challenges. For example, the existing airport cargo terminal processing methods cannot handle the complex and diverse entry and exit processes of different types of goods, which greatly reduces the processing capacity of the airport cargo system when the airport cargo system is busy.
