1. A system of an industrial Internet of Things (IoT) for an automated guided vehicle (AGV) control, comprising a service platform, a management platform and a sensor network platform connected in sequence, wherein the management platform includes:
a modeling module configured to obtain an AGV circuit layout of a target workshop through the sensor network platform, and add pre-planned paths of all AGVs to the AGV circuit layout to form an AGV operation model;
an obtaining module configured to obtain 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;
a calculation module configured to assign an operation speed to the each AGV of the all AGVs in the AGV operation model, and calculate, 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;
a determination module configured to determine that a current operation process is unqualified when any two of operation tracks reach a same node at a same time, and adjust the operation speed to recalculate the operation tracks until the operation process is qualified; and
a control module configured to control 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 send 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 determination module is further configured to:
obtain 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 circuits in the AGV operation model;
process the number of the key nodes as an adjustment weight and assign the adjustment weight to each of the pre-planned paths of the all AGVs; and
when adjusting the operation speed, adjust the operation speed corresponding to the each of the pre-planned paths of the all AGVs according to the adjustment weight.
