PURPOSE: A safety driving system for a forklift using RFID is provided to detect risk factors around a forklift truck using RFID signals and alarm the risk factors in advance. CONSTITUTION: A safety driving system for a forklift using RFID comprises a receiver(300) and a controller. The receiver receives a wireless signal transmitted from a location tag(200), and the receiver includes an antenna unit comprising two or more directional antennas(310) which are arranged at regular angle intervals around a center shaft and a driving unit which rotates the center shaft for omnidirectional detection of the antenna unit. The controller calculates the distance to the location tag based on the wireless signal and, if the tag is in a preset distance range, generates a risk signal. |
