基于C8051F340的模拟飞控仿真器的设计与实现

摘要

In order to debug and inspect the back-end analog equipment quickly and efficiently, a portable analog flight-control simulator was designed and implemented, C8051F340 was used as the main control chip in the simulator, AD conversion circuitry was built by AD5722, the interface to transfer data with computer was USB2.0, the simulator can output two differential signal. Firstly, the overall structure of the analog flight-control simulator was introduced briefly, secondly the design and implementation of the hardware and software of the simulator was described in detail, and the computer interface figure was provided. It has been used in the actual examination and troubleshooting work, it is able to improve work efficiency and good stability.%为了向后端模拟设备提供快速有效的调试和检查功能，设计并实现一种便携式模拟飞控仿真器，该仿真器采用C8051F340作为主控制芯片，通过AD5722搭建DA转换电路，以USB2.0作为与上位机数据传输的接口，可同时输出两路差分模拟阶梯信号。首先简要介绍模拟飞控仿真器的总体结构，其次详细说明了该仿真器的软硬件设计及实现方法，并给出了上位机界面图。仿真器已经应用在实际的检查排故工作中，提高工作效率，稳定性良好。
