1. An Industrial Internet of Things for determining a material transportation path and for controlling Automated Guided Vehicles (AGVs), comprising a sensor network platform, a management platform and a service platform connected in sequence, wherein the management platform includes:
an obtaining module, configured to generate a first layout directed graph according to an AGV circuit layout of a target workshop obtained through the sensor network platform, wherein nodes of the first layout directed graph include AGV circuit intersections, a material start point, and a material end point, an edge of the first layout directed graph is an AGV circuit, and a weight of the edge is a length of the edge;
a material module, configured to assign a material requirement of a target process to a corresponding material end point and assign a material supply corresponding to the material requirement to a corresponding material start point;
a reconstruction module, configured to reconstruct the first layout directed graph according to the material end point of the first layout directed graph to form a second layout directed graph, and form a third layout directed graph based on the second layout directed graph, wherein each node of the second layout directed graph corresponds to a category of material;
a first calculation module, configured to calculate a first path in the third layout directed graph, wherein the first path is a shortest path passing through all nodes corresponding to the same material;
a correction module, configured to form an intermediate layout directed graph based on the first path and the second layout directed graph;
a second calculation module, configured to calculate a second path in the intermediate layout directed graph, wherein the second path is an optimal path from the material start point to a corresponding node of the start point of the first path; and
a merging module, configured to merge the first path and the second path into a final AGV path and to dispatch the AGVs with the final AGV path.
