Ground Position Detection and Communication System

Details

I. Introduction
Ground position detection and communication system is a rising applied technology for realizing industrial locomotives automation, which is helpful to industrial mobile locomotives position detection and data communication. It is of high positional accuracy, high stability, and high reliability, particularly suitable for harsh industrial environments because of its unique advantages, and widely used in coking, steel warehouse, iron-making, steel rolling, electrolytic aluminum, train, material distributing in material yard, feedstock and reclaim, port and wharf, chemical engineering, energy and many other fields.


II. Structure
The ground position detection and communication system can realize position detection and data communication by using electromagnetic induction principle. It consists of three parts: ground part, encoded cable part and vehicle part. Ground part contains: ground communicator, address detector, and ground power; Encoded cable part contains: proximal box, encoded cables, interval box and terminal box. Vehicle part contains: vehicle power, vehicle communicator and antenna box. Since it collects position information on ground, it is suitable for single locomotive working or occasions which didn’t require high realtime position information.
