Claim 5:
6. A method of an industrial Internet of Things (IoT) for an automated guided vehicle (AGV) control, the method is applied to a service platform, a management platform, and a sensor network platform connected in sequence, wherein the method is executed by the management platform;
the method comprising:
obtaining an AGV circuit layout of a target workshop through the sensor network platform, and adding pre-planned paths of all AGVs to the AGV circuit layout to form an AGV operation model;
obtaining a feeding time of each material end point within a preset period, each AGV of the all AGVs in the AGV operation model being fed for at least once within the preset period, and the material end point being a node for receiving material in the AGV operation model;
assigning an operation speed to the each AGV of the all AGVs in the AGV operation model, and calculating, based on the operation speed and the feeding time, an operation track of the each AGV of the all AGVs in the AGV operation model within the preset period;
determining that a current operation process is unqualified when any two of operation tracks reach a same node at a same time, and adjusting the operation speed to recalculate the operation track until the operation process is qualified; and
controlling an operation of the each AGV of the all AGVs in the AGV operation model according to the operation track of the each AGV of a qualified operation process, and sending the operation track of the each AGV of the qualified operation process to a user platform through the service platform to display to a user;
the adjusting the operation speed comprising:
obtaining a number of key nodes that the pre-planned paths of the all AGVs pass through in the AGV operation model, wherein the key nodes are intersections of AGV lines in the AGV operation model;
processing the number of the key nodes as an adjustment weight and assigning the adjustment weight to each of the pre-planned paths of the all AGVs; and
when adjusting the operation speed, adjusting the operation speed corresponding to the each of the pre-planned paths of the all AGVs according to the adjustment weight.
