Linear drive conveyor

A method of controlling a transport carriage in a warehouse facility, said method comprising:

• providing a conveyor system having an array of guide tracks configured to support and guide a transport carriage as it moves throughout the warehouse facility, wherein said carriage is propelled by a drive system having a series of drivers disposed along said guide track;
• determining that said carriage is to be transported from one location in the warehouse facility to a required location;
• activating a first one of said series of drivers that is proximate said carriage to push or pull said carriage along said guide track in said direction of said required location without contacting said carriage;
• and
• activating a second one of said series of drivers downstream of said first driver to continue pushing or pulling said carriage along said guide track in said direction of said required location.

A conveyor system adapted to control processing operations comprising:

• a trunk network;
• a SYNC network for coordination of motion between a first driver and a second driver;
• and
• a trigger configured to address and sync one or more interrupts of said trunk network;
• wherein said SYNC network causes one of said first driver or said second driver to communicate a present state of the said first or second driver.
