Passive space perception interaction method of entities in campaign simulation based on discrete events

Abstract

The invention provides a passive space perception interaction method of entities in campaign simulation based on discrete events. A space perception interaction model is arranged, wherein the model includes a space grid list, a campaign entity list and a sensor list. A space perception interaction manager is used for providing a function calling interface for a campaign entity model and sensor components. When the situation that the campaign entities enter or leave the space grid is discovered, a space perception interaction event is transmitted so that the corresponding campaign entities in the sensor list are enabled to receive the space perception interaction event and then detect the campaign entities entering or leaving the space grid. The simulation propulsion mechanism based on thediscrete events is adopted, and the time step of simulation propulsion is not a constant and is determined by the occurrence time of the event so that the computation burden can be reduced and the simulation efficiency can be enhanced. The space perception interaction manager is embedded in the simulation engine in the form of a component so that the expandability of the simulation system and thereusability of the simulation model can be enhanced and the simulation model development efficiency can be enhanced.

Description

technical field [0001] The present application relates to the field of combat simulation, and in particular, relates to a passive space perception interaction method for entities in discrete event-based combat simulation. Background technique [0002] Combat simulation is an important means to study war issues, analyze and evaluate combat schemes under different technical backgrounds. In recent years, a variety of combat simulation systems have been established to support combat simulation training at different combat levels and in different combat domains, research on combat issues, and assist decision-making in combat plans. In the combat simulation system, the entity's battlefield space perception is the observation and acquisition of battlefield environment information by the combat entity, the discovery and identification of the target entity, and the information input of complex military action decisions, which affect the combat entity's reconnaissance, detection, earl...

AI Technical Summary

Problems solved by technology

Although the algorithm of the spatial perception interaction model based on the full scan of the simulation entity is simple, it wastes a lot of computing resources. In each time step, it is necessary to scan all the simulation entities and judge the spatial distance.

However, during the simulation process, the target entity may not appear in the perception range of the entity for a long time, or the target entity is in the perception range, but there is no spatial movement for a long time, so the spatial perception interaction calculation of the entity is not required

In the process of combat simulation, there are perception, detection, and reconnaissance among a large number of combat entities, and a large number of physical space perception interaction calculations are required, and the calculation amount is N 2 (where N is the number of combat entities), which reduces the efficiency of simulation operation
