The present disclosure provides an industrial Internet of Things for controlling a supply of accessories and control methods. The industrial Internet of Things comprises a user platform, a service platform, a management platform, a sensor network platform, and an object platform interacting in sequence. The object platform is configured to include different accessory supply devices, each of which is configured with a data collector. The sensor network platform receives and sends accessory supply data to different management sub-platforms. The different management sub-platforms receive the different accessory supply data, after data processing, store and send at least one processing result data to different service sub-platforms. The different service sub-platforms receive and send corresponding processing result data to the user platform separately. The user platform generates a first instruction to a corresponding service sub-platform based on the at least one processing result data.
