Claims9
A method for RF communication between an automated guided vehicle and a plurality of manufacturing equipment in an automated material handling system, said manufacturing equipment transfers materials throughout the materials handling system
- through the plurality of manufacturing equipment to be retrieved by said automated guided vehicles,
- said automated guided vehicle comprises an automated vehicle communication
- unit that includes an initialization setting transmission module for transmitting
- information related to an initialization setting of the automated guided vehicle, and
- the manufacturing equipment includes an equipment communication unit that includes an initialization setting reception module for receiving information related to
- initialization setting;
- the method comprising the steps of:
- transmitting, by the initialization setting transmission module, automated vehicle RF initialization information by the automated vehicle communication unit to at least one of the manufacturing equipment, wherein automated vehicle RF initialization information including an automated vehicle ID and RF channel information is registered;
- receiving, by the equipment communication unit, the automated vehicle RF initialization information from the automated vehicle communication unit through the initialization setting reception module, wherein the equipment RF initialization information is registered and said equipment RF initialization information includes an equipment ID;
- initializing an RF communication module in the equipment communication unit based on the automated vehicle initialization information, the equipment communication unit receives the automated vehicle RF initialization information through the initialization setting reception module;
- converting, by the equipment communication unit, the equipment RF initialization information into an RF signal through the RF communication module, and transmitting the RF signal to the automated guided vehicle;
- initializing, by the automated vehicle communication unit, a first RF communication module based on the equipment RF initialization information from the equipment communication unit;
- and
- transmitting and receiving, with an RF signal, information related to loading and unloading of materials through the RF communication module of the automated vehicle communication unit and the RF communication module of the equipment communication unit.
The method for RF communication between the automated guided vehicle and manufacturing equipment in an automated material handling system, wherein a barcode corresponding to equipment RF initialization information including at least one of an equipment ID, an RF channel, and a communication medium is attached to the manufacturing equipment, and the automated vehicle communication unit acquires the equipment ID for the corresponding manufacturing equipment through a barcode recognition means, and transmits automated vehicle RF initialization information and the acquired equipment ID to the manufacturing equipment through the initialization setting transmission module.
A method for RF communication between an automated guided vehicle and manufacturing equipment in an automated material handling system transferring materials, the method comprising the steps of:
- transmitting, by an equipment communication unit, equipment RF initialization information on a predetermined cycle through an initialization setting transmission module, wherein the equipment RF initialization information including an equipment ID and an RF channel is registered and is attached to manufacturing equipment wherein the automated guided vehicle includes an automated vehicle communication unit wherein automated vehicle RF initialization information and an automated vehicle ID is registered;
- receiving equipment RF initialization information from the manufacturing equipment through the initialization setting reception module;
- initializing, by the automated vehicle communication unit, a first RF communication module based on the equipment RF initialization information received through the initialization setting reception module;
- and
- transmitting and receiving information related to loading and unloading of
- materials by an RF signal through a first RF communication module of the automated vehicle communication unit, and a second RF communication module of the equipment communication unit.
