With the rapid development of my country's aviation industry, the volume of air passenger traffic is increasing year by year, so airline staff are increasingly tasked with checking passenger luggage. Based on the management regulations of major airlines on the carry-on items of passengers, there are corresponding restrictions on the weight and number of luggage according to the type of ticket (first class, business class, economy class) held by passengers, and the length and width of each carry-on item are required , height shall not exceed 55cm (3 inches), 40cm (15 inches), 20cm (7 inches), and the sum of the three dimensions of a single piece shall not exceed 158cm. Items exceeding a certain weight, number of pieces, and volume limit shall be checked as checked baggage. The volume and weight data of luggage are very important for airlines. On the one hand, the settlement of overweight baggage and baggage consignment fees between passengers and airlines requires accurate measurement of volume and weight; It also has a very important meaning.

At present, airlines still use ordinary platform scales or platform scales to measure the weight of luggage, and when the volume needs to be measured, they generally use tools such as tape measure to measure manually. In this traditional method, the luggage measurement process is done manually, which is inefficient; especially in volume measurement, due to the backward tools used, the measurement process is likely to cause disputes between passengers and operators; and the obtained data is also Isolated from the overall information flow of the airport operational data management system. As passengers' requirements for boarding efficiency and service quality continue to increase, this method is increasingly unable to meet the requirements of efficient and accurate modern life, and most airports have the following deficiencies in the detection of passenger luggage volume and weight (1) The accuracy of the measurement result is not high; (2) The measurement efficiency is not high; (3) The application and function cannot meet the requirements of airlines for real-time feedback and management of passenger baggage data.

It can be seen that the invention of an airport-oriented automatic luggage volume and weight measurement device will help improve the standardization management level of the airport's passenger luggage, improve the efficiency of passenger boarding, and provide more accurate and convenient passenger luggage for airports and airlines. monitoring and management methods.
