摘 要: | 针对航空发动机传感器地面仿真实验中存在的缺陷进行了深入研究,提出了一种采用硬件在环仿真的全新模式,解决了传统实验操作复杂、易受干扰、扩展性差等不足。仿真系统基于可扩展处理平台Zynq[1],移植了适合嵌入式系统的小型TCP/IP协议栈LwIP[2],可接入综合实验网络。对于不同的实验要求,只需调整接入网络的设备数量,大幅提高了可扩展性,便于系统集成。用户无需进入实验室,就能完成模型仿真、参数验证、数据测试等一系列操作。实际使用效果表明,新型仿真系统的综合性能大幅优于传统模式。在航空发动机的仿真与测试方面,提供了一种高效便利的解决方案,可提升实验效率30%以上。目前已被成功应用到多型航空发动机综合实验中。

Design of Simulation System for the Sensor in Areo Engine Based on ZYNQ |

Abstract: | Aiming at the shortcomings of areo engine sensor in the ground test, a deep research is carried out to propose a new mode of hardware-in-the-loop simulation. It solves the problems of traditional complex experimental operation, vulnerable to be interfered and bad scalability. Based on the extensible processing platform Zynq, the simulation system, with suitable embedded systems, transplants the small TCP/IP protocol stack LwIP, which can be connected to the comprehensive experimental network. For different experimental requirements, the scalability is improved and system integration is easy to realized by adjusting the number of devices accessing the network. Users is able to complete a series of operations such as model simulation, parameter verification, and data testing without entering the lab. The results of practical use show that the comprehensive performance of the new simulation system is much better than the traditional mode. It provides an efficient and convenient solution in the simulation and testing of aero engines. Besides, it can improve the experimental efficiency by more than 30% and be successfully applied into poly-type areo engine comprehensive labs. |
