发明名称 PROXIMITY DETECTION SYSTEMS AND METHOD FOR INTERNAL TRAFFIC CONTROL
摘要 Embodiments described herein relate to proximity detection systems and a method for internal traffic control in a work zone. In various embodiments, magnetic field generators generate respective oscillating magnetic fields for detection by magnetic field detectors. The magnetic field detectors generate a signal for providing a visual and/or audible warning to operators in response to detecting the magnetic field.
