In order to realize the rapid construction and application of simulation system, a distributed simulation integrated development framework based on high level of architecture (HLA) was proposed. Based on the encapsulation of HLA-RTI core functions, an integrated tool service architecture is designed to meet the requirements of simulation test design, execution and analysis, and realize the functions of model development, system integration, scenario editing, situation display, data recording and analysis. The results show that the design provides an agile, efficient and complete supporting environment for the development and integration of distributed simulation system.
