The invention discloses a process industry network model building method and system based on data. The method comprises the steps that data nodes are set, wherein a plurality of production devices arecontained in a flexible job shop, each production device is called as a process node, a plurality of sensors are arranged on each production device, and each senor is called as a data node; the datais preprocessed, wherein the data collected by each sensor is stored into a corresponding two dimensional table, the preceding collected numerical value is compared with the present collected numerical value, and the present data is modified as +1 or 0 or -1; edges are arranged for the selected data nodes, wherein +1 or 0 or -1 is used as the input value of an Apriori algorithm, the association relationships between different sensors on the same production device and the association relationships between the preceding and present sensors, which are connected, on different production devices are calculated respectively,
