Electronic Customs Clearance and Entry-Exit Judgment Methods at Land Ports

Abstract

The invention discloses an electronic inspection clearance and entry-exit judging method for land ports; the multi-radio-base-station technology and double work frequency band technology are implemented based on electronic inspection clearance for the land ports; the multi-radio-base-station technology enhances reliability and stability of base station design by arranging a plurality of radio base stations on clearance routes of cars at land ports; as the radio base stations are not always located on theoretical optimal position points as a result of complicated areas of the ports, the double frequency band technology with 433MHz frequency band and 920MHz frequency band is used to realize the normal work of the radio base stations within a distance range of 300m in the environment with high traffic density and obstacle shielding. According to the invention, one-stop service of electronic inspection clearance of cars can be achieved, the clearance efficiency of the cars can be greatly enhanced and the manual complicated operation of the ports is simplified.

Description

technical field [0001] The invention relates to a method for electronic inspection clearance and entry-exit judgment at a land port. Background technique [0002] With the development of economic globalization, port customs clearance has become an important link in the development of modern logistics industry, which is related to the competitiveness of enterprises and the development of foreign trade. The land port is the main channel for the trade of goods and the free movement of people. The means of transportation include freight vehicles, passenger vehicles and cross-border vehicles. Take Huanggang Port, the largest land port in Asia, as an example. In 2010, 9.78 million vehicles entered and exited the country, and more than 20,000 vehicles crossed the border every day. Such a huge traffic flow requires the port management unit to continuously adopt advanced technology to realize fast inspection and release under the premise of effective supervision. The declaration met...
