The invention discloses a product
full life cycle management method based on a digital identifier, and belongs to the technical field of product management, and the method specifically comprises the steps: generating a digital identifier based on an initial
bill of materials, writing the digital identifier into a product
radio frequency tag, and registering the digital identifier to a block chain; periodically collecting
label signal intensity and spatio-
temporal information to form a physical track
record and uploading the physical track
record to the block chain; when the
signal is continuously lower than a dynamic threshold value, judging that the physical
signal is interrupted and triggering a logic tracing program, analyzing a
product model in the digital identifier, and retrieving a corresponding
bill of materials; searching supplier data according to the
list to determine preparation suppliers, and extracting logistics coordinates and timestamps of recent supply of each supplier from the block chain to form a replacement tracing
data set; fusing the physical track
record and the
data set according to a
time sequence to generate a
full life cycle data graph; according to the invention, continuous and complete tracing of the
full life cycle data of the product under the condition of physical signal interruption is realized.
