operating method of Real time locating system of multiple-estimating for port logistics environment

摘要

The invention of the container mouth, out of distance measurement based on the frequent application of location-aware environment in real Pier relates to a system, a plurality of the reader and precise measurement performance when measuring the position of a tag attached to the device, to improve the success rate of a method for ensuring the accuracy and Kane real-time position information. The system reader, a tag, an object of the engine consists of a position calculation system, and the property of the environment is a pier, i.e. YT (Yard Tractor), TC (Transfer Crane) is a real-time tracking of a moving position and so on. Location information is input stationary reader is installed on towers measuring the position of the mobile reader attached to the TC, and the tags and the wireless communication is easily portable reader is installed in the position of each TC is attached to the tag and from the passage YT is measured using a linear distance information. This multi-stage position measurement is designed in consideration of the characteristics of the pier by the interference environment may reduce the position measuring accuracy and to improve the success rate as well as the container, such as iron in the port environmental obstacles. The position calculation engine for performing position location using the distance information from the mobile reader and fixed reader YT, TC, such as measuring the position and plays a role in communication with each of the location information management and other systems. ;
