Guidance control semi-physical simulation system timing method and guidance control semi-physical simulation system timing system

Abstract

The invention provides a guidance control semi-physical simulation system timing method and a guidance control semi-physical simulation system timing system. The method comprises the steps of performing clock controlling by an RTX real-time operation system which is installed on a timing management test computer, and generating timely interruption of an RTX high-precision clock; performing broadcast interruption through a VMIC reflective memory network when counting time is up, writing a frame period counting value in a specific address of the VMIC reflective memory network, wherein the counting value is the number of time frames in a simulation experiment; after each system node computer receives the interception, reading the counting value of the frame period in the specific address of the VMIC reflective memory network, calculating a data reading address according to the frame period counting value, performing model resolving, and writing the result into the VMIC reflective memory network. The guidance control semi-physical simulation system timing method and the guidance control semi-physical simulation system timing system can settle problems of data synchronization and clock synchronization between nodes of an existing semi-physical simulation system.
