Abstract:
1. A method of controlling automated guided vehicles (AGVs) being performed by execution of computer readable program code by a processor of a server, the server communicating with one or more work machines and AGVs via a wireless network, the method comprising: receiving a first request signal for desired material from a work machine; analyzing the first request signal to determine a location of the work machine, and searching for an AGV that has the desired material, is idle, and is closest to the work machine, according to basic information of a production scene that are stored in a storage device of the server; setting the location of the work machine as a first target location of the searched AGV, determining a first movement route of the searched AGV based on a starting location of the searched AGV, the first target location, and arrangement information of AGV tracks obtained from the basic information of the production scene; generating a first control command based on the starting location, the first target location, and the first movement route of the searched AGV; sending the first control command to the searched AGV, to control the searched AGV to move to the first target location, to deliver the desired material to the work machine; receiving a second request signal generated by the searched AGV as all the desired material carried by the searched AGV has been removed; analyzing the second request signal to determine a current location of the searched AGV; setting a storage location of the desired material recorded in the basic information of the production scene as a second target location of the searched AGV, and determining a second movement route of the searched AGV based on the current location, the second target location, and the arrangement information of the AGV tracks; generating a second control command according to the current location, the second target location, and the second movement route of the searched AGV; and sending the second control command to the searched AGV, to control the searched AGV to move to the storage location of the desired material, to reload the desired material to the searched AGV.
