Simulation method for synchronously controlling a plurality of airplanes

Abstract

The invention discloses a simulation method for synchronously controlling a plurality of airplanes, belonging to the technical field of military simulation. The method is improved based on a traditional simulation method of synchronous airplane control and a method based on the synchronous multi-airplane control of RTX (Real Time Exchange) semaphore is provided so that the synchronous simulation of a plurality of airplanes in a computer has improved accuracy. The method has the advantages of strong real-time property, high simulation accuracy, good expansibility, and the like, relates to the interaction of four parts, i.e. an airplane model, an RTX signal semaphore, a shared memory and a user program, is mainly applied to the industrial simulation field and is significant to pilot simulation training, large-scale power system simulation, large-scale military real-time simulation, large-scale crowd motion simulation, and the like.

Description

technical field [0001] The invention belongs to the technical field of military simulation and is derived from the engineering practice of "computer-generated forces". Background technique [0002] The invention can realize "synchronous" calculation and simulation of a plurality of aircraft models in a computer, and its technology can be applied to the field of military simulation and also to the field of civilian simulation. [0003] The traditional aircraft synchronous control method only allows multiple aircraft models to interact with the user program "sequentially" in the computer. However, this "sequence" cannot be guaranteed in each calculation cycle of the aircraft model. [0004] Because each aircraft model appears in the form of a "process" in the computer, the execution of the process must be called and allocated "time slices" multiple times by the operating system, especially the complex operating system process based on the aircraft model. We call the feature t...

Problems solved by technology

Therefore, as long as the process has not finished executing, it is impossible to know exactly when it is scheduled

In this way, the "synchronization" of the execution of multiple aircraft models cannot be guaranteed

In other words, we cannot completely copy the processing method of the operating system process to control the aircraft process to synchronize them

[0014] Furthermore, in the dual-aircraft formation flight simulation, when we want to control two aircraft models for formation simulation, if the calculation results of the aircraft model process are not synchronized, it will bring great "disturbance" to our feedback control system. It will cause the output instability of the controlled object, the bump of the running track of the controlled object, and cause the simulation display system to produce "jitter" and unreasonable behavior.
