Embodiment Construction

[0030] The purpose of the present invention is to propose a helicopter simulator subsystem scheduling method for efficiently scheduling them for simulation and data interaction to reduce transmission delays and meet the requirements of high-level helicopter simulators on transmission extension.

[0031] In order to achieve the above object, the technical solution of the present invention is: a helicopter simulator subsystem scheduling method, based on a helicopter simulator simulation management platform, its interface cross-connection relationship with each subsystem of the helicopter simulator is as follows: figure 1 shown. The simulation management platform defines the scheduling priority and calculation time of each subsystem of the helicopter simulator, stores the output interface set and input interface set of each subsystem of the helicopter simulator, and creates and maintains the interface data of the whole system of the helicopter simulator pool; the steps to dispatc...

Abstract

The invention discloses a helicopter simulator subsystem scheduling method, belonging to the field of helicopter simulator flight simulation design. The method comprises the following specific steps: step 1, setting scheduling priorities for all subsystems Si, wherein i is equal to 1, 2,..., n; step 2, distributing resolving time ti for each subsystem; step 3, determining an output interface set oi and an input interface set Ii of each subsystem of a helicopter simulator, and calculating an output interface set O and an input interface set I of the whole system of the helicopter simulator; step 4, establishing a unified template type T of a helicopter simulator interface; step 5, instantiating all elements in the whole-system output interface set O by using the unified template type T of the helicopter simulator interface, and establishing a whole-system interface data pool of the helicopter simulator; and step 6, in each simulation period P of the helicopter simulator, according to the scheduling priority of each subsystem of the helicopter simulator, scheduling each subsystem Si in sequence from high to low, and carrying out analog simulation.

Description

technical field [0001] The invention discloses a helicopter simulator sub-system scheduling method, which belongs to the field of helicopter simulator flight simulation design. Background technique [0002] The helicopter simulator is composed of multiple subsystems such as helicopter performance simulation, control load, avionics simulation, comprehensive environment simulation, sound simulation, instructor console, vision, movement, and weapon simulation. Periodically interact with data and coordinate work. [0003] There is a certain transmission delay in the process from the input signal sent by the control load subsystem of the helicopter simulator to the output response of the visual subsystem. GJB5449 "General Requirements for Helicopter Flight Simulators" requires that the transmission delay of helicopter simulators above Class C should not exceed 100 milliseconds. If the helicopter simulator adopts the data interaction method of two-two communication between subsy...
