Product manufacturing unified value chain middleware technical method and digital twin system thereof

The invention relates to the technical field of industrial control, and provides a product manufacturing unified value chain middleware technical method and a digital twin system thereof, and the method comprises the following steps: building a middleware platform comprising an industrial control protocol adapter and a block chain network; designing an equipment resource access interface for acquiring data from the block chain network; transmitting production and manufacturing equipment data corresponding to the plurality of production scenes to a middleware platform through an industrial control protocol; the middleware platform uniformly converts the format of the received data into a preset format by using an industrial control protocol adapter, and directly uploads the data with the uniform format to a block chain network; the block chain network carries out encryption processing on the data with the uniform format; constructing a digital twin system for simulating and analyzing a production scene based o
