A method for group control AGV to communicate with station-side general control center and mobile terminal

Abstract

The invention relates to a method for realizing communication between group control AGVs (Automated Guided Vehicles) and a station end master control center as well as a mobile terminal. The method isapplied to an AGV device system. The AGV device system comprises an AGV group, a wireless network module, a station end master control center and a mobile terminal. According to the method, a communication protocol is adopted to realize bidirectional communication between the station end master control center and the AGV group, direct communication between the mobile terminal and the AGV group without a master control platform and communication among AGVs in the AGV group; the communication protocol comprises a protocol layer and a command layer; the protocol layer comprises a starting identifier, a source identifier, a command length identifier and a verification identifier; the command layer comprises an operation command and command content; the operation command comprises a transmission command and a response command; and the command content is in a mode in which content and the byte quantity are variable. Through adoption of the method, meaningless commands are not carried and the quantity of meaningful commands is not limited during communication, so that the communication data volume can be reduced to the maximum extent while effective communication is ensured.
