the service platform and the sensor network platform both use a centralized arrangement, and the management platform uses an independent arrangement; the centralized arrangement means that a platform uniformly receives data, uniformly processes data, and/or uniformly sends data; the independent arrangement means that a platform uses different sub-platforms to store, process, and/or transmit different types of data;

the management platform comprises a plurality of sub-platforms; each of the sub-platforms corresponds to a type of a production line stage; the type of the production line stage comprises a first stage and a second stage associated with the first stage;

when the management platform receives sensing detection data transmitted by the object platform, the sensing detection data is presented to the user platform by the service platform after being processed by a sub-platform corresponding to the sensing detection data; and

when the management platform sends a control command to the object platform, a control parameter of the type of the production line stage is calculated by a sub-platform corresponding to the type of the production line stage, and the control parameter is sent to the object platform as the control command.
