防火系统仿真设计与验证

Design and Verification of Fire Protection System Based on Flight Simulation

分析飞机防火系统的仿真需求，从硬件和软件两个方面分别入手给出了防火系统仿真方案。接着，基于三级关联的关系研究了系统传感器、探测子系统、火警子系统和灭火子系统等仿真模型，最后建立了防火系统软件仿真模型。经验证，所建立的系统模型能充分满足高等级飞行模拟器的仿真需要，具有很高的实时性和逼真度。

The system structure of fire protection simulated system is proposed according the demands on flight simulation. Further, the three-step correlation method was used to model the detection sensor, detection subsys- tem, fire warning and fire extinguish subsystem of the key devices. And fire system simulated model was stabi- lized based on device model. And then, the accuracy of the simulated system model is verified by the VVA doc- ument and test. On a whole, its interface is friendly and operation is easily, the simulated result is real-time and correct, and almost in line with the airplane.
