The invention provides an industrial control anomaly detection method based on a distributed environment. The method comprises the following steps: acquiring a network data packet; analyzing and preprocessing the acquired data, converting the data into an adjacent matrix form, and constructing a directed graph; dividing the graph into a plurality of sub-graphs, and inputting the sub-graphs into a plurality of servers for training; and after model training is completed, inputting actual industrial control network data into the model, and judging whether the actual industrial control network data is abnormal or not. According to the invention, a distributed architecture is adopted, so that the performance and time overhead required by the host during training are greatly reduced. The invention further provides an industrial control anomaly detection system based on the distributed environment.
