Systems and methods of remotely controlling a materials handling vehicle

摘要

A method of synchronizing a transmitter and a receiver in a supplemental remote control system for materials handling vehicle. The vehicle has a receiver for receiving wirelessly transmitted travel commands and from a wireless remote control device associated with an operator of the vehicle. The method comprises initiating a power on sequence to enable a materials handling vehicle for operation; entering a pairing mode to synchronize the receiver and a corresponding controller on said vehicle to a select one of a plurality of wireless remote control devices; receiving pairing mode confidence signals at said receiver, wherein each pairing mode confidence signal provides a transmitter identification that uniquely identifies a corresponding remote control device within range of said receiver; matching a known transmitter identification code with a corresponding one of the pairing mode confidence signals received by the receiver; and synchronizing the selected remote control device to the receiver and the controller such that the vehicle acknowledges remote travel commands only from the selected remote control device.
