The invention discloses a method for realizing distributed simulation synchronization. The method comprises the following steps: a heartbeat server calculates the heartbeat step length of a distributed simulation system; the heartbeat server periodically transmits a heartbeat data packet which comprises the number of heartbeats and a heartbeat step length to each simulation node at the interval of heartbeat step length, wherein the number of heartbeats is a periodicity N at which the heartbeat server transmits heartbeat data at present, and N is a positive integer; and each simulation node receives the heartbeat data packet transmitted by the heartbeat server and determines whether node simulation needs to be impelled according to the number of heartbeats. By adopting the method, the propulsion of the node simulation is driven by transmitting heartbeat data through the heartbeat server based on a heartbeat mechanism, the simulation performance is not reduced along with the increase of node numbers, the simulation synchronization in a large-scale distributed simulation system is adapted, different requirements of distributed simulation can be met, high instantaneity is achieved, and the simulation system has high overall performance.
Description
technical field [0001] The invention relates to a realization method of distributed simulation synchronization, in particular, it is applicable to the realization method of simulation synchronization in a large-scale distributed simulation system. Background technique [0002] In the distributed simulation training system based on the high-level architecture HLA (High Level Architecture), in order to ensure the synchronization of event execution sequence and causal logic between simulation nodes, time management services based on various strategies are currently used to achieve this. The management service is to sort the messages in the distributed simulation through logical time, to ensure that the timing relationship of events occurring in the simulation system is consistent with the timing relationship in the real world, and to ensure the correct progress of the simulation. [0003] However, the time management mechanism is based on the Time Stamp Order (TSO) method. In o...
