The paper designs POL service simulation training framework system. Starting from the analysis of POL service simulation training system’s features, it provides the design objective of POL service simulation training system. As an example of field depot unit, simulation training system design is set up. It annlyzles the key component of POL service simulation training system, simulates field depot unit simulation training subsystem using the related technology and designs field depot system simulation training process figure. It sets up the content of POL service simulation training system preliminarily and improves the quality effectiveness of POL service informationization training.
