Initialization setting method for RF communication of unmanned transporting device in automated material handling system

An RF initialization setting method of an unmanned transporting device in an automated material handling system which includes an unmanned transporting device configured to convert information transmitted through a data terminal in a state when a selecting terminal is set to a second level into an RF signal to transmit the converted RF signal to a manufacturing facility, and performs RF communication with the unmanned transporting device to transport a carrier to the manufacturing facility, the method comprising:

• a data stream generating step of generating one or more data streams formed of a setting value and a command value in a predetermined bit unit for the setting value for each RF initialization parameter and has a bit number corresponding to the number of data terminals by the unmanned vehicle controller of the unmanned transporting device, in which the one or more data streams are generated for said each RF initialization parameter;
• an initialization information transmitting step of setting a state of the selecting terminal to a first level and transmitting information in a data stream unit to an unmanned vehicle communication module through the date terminals, by the unmanned vehicle controller;
• and
• a setting value registering step of receiving the one or more data streams applied from the unmanned vehicle controller through the date terminals in a state when the selecting terminal is a first level and obtaining and sequentially disposing unit setting values based on command values of the received one or more data streams to regenerate and register the setting value for said each parameter, by the unmanned vehicle communication module.
