SYSTEM FOR DETECTING ANGLE OF ARTICULATION ON AN ARTICULATING MINING MACHINE

摘要

A system and method for detecting a position of a person or second machine relative to a machine is provided. The system includes a transmitter system located on the machine, a locator for being carried by the person, means for determining the position of said locator relative to the transmitter system, means for defining one or more safety zones around the machine; and warning means for generating a signal when said locator enters into any of said one or more safety zones. The transmitter system includes a controller for generating a uniquely encoded magnetic signal and a plurality of drivers in communication with the controller for transmitting the uniquely encoded magnetic signal. According to the method a uniquely encoded magnetic signal is generated and transmitted around the machine from a transmitter system located on the machine. The magnetic signal is received and processed at a locator carried by the person. A locator radio frequency signal is transmitted from the locator in response to the received and processed magnetic signal. The locator radio frequency signal is received at the transmitter system. An algorithm is performed at the transmitter system based on the magnetic signal and locator radio frequency signal to determine the position of the locator relative to the transmitter system.
