【摘要】：机场跑道的各种异物(FOD),包括飞机遗落的工具、掉落的零件、外来的石头、塑料制品等等。这些机场异物严重威胁着飞机和乘客的安全,对这些异物的探测成为保证飞机起飞安全的迫切需求。针对该需求,在某项目的支持下,我们研制了某FOD探测雷达,本文则着重研究了该雷达的软件设计与实现。本文的主要工作如下:(1)对FOD检测雷达的下位机软件进行了设计与实现,该下位机软件是在ADSP TS20X芯片上用VisualDSP++软件编程实现的。该下位机中实现的主要功能模块包括:数据接收模块(链路口)、数字信号处理模块(FFT和加窗)、门限检测模块、模式检测模块和图像量化模块、数据存储及发送模块等。文中给出了该下位机软件各个关键模块的详细设计过程和核心代码,并给出了部分测试结果。(2)在上述设计的基础上,本文进一步用VC++软件设计和实现了 FOD检测雷达的上位机软件。首先设计了上位机软件的总体框图,并进一步设计了上位机软件和下位机软件的协作流程,包括上位机开机流程、串口连接流程、上位机发送工作指令流程。在此基础上,设计并编程实现了上位机软件,该上位机软件的主要模块包括串口通信模块、数据处理模块(包括实时目标数据处理和图形数据处理)、界面显示模块(包括参数设置模块和绘图模块)。最后对软件系统进行了联合测试。该系统已经实际用于对某机场跑道进行异物检测。
[Abstract]:A variety of foreign objects on the runway, including aircraft tools, falling parts, exotic stones, plastic products, etc. The foreign bodies in these airports threaten the safety of aircraft and passengers, and the detection of these foreign bodies becomes an urgent need to ensure the safety of aircraft takeoff. In order to meet this demand, we have developed a certain FOD detection radar under the support of a certain project. In this paper, the software design and implementation of the radar are emphatically studied. The main work of this paper is as follows: (1) the software of FOD detection radar is designed and implemented. The software is programmed on ADSP TS20X chip with VisualDSP software. The main function modules of the lower computer include: data receiving module (link intersection, digital signal processing module, FFT and windowing), threshold detection module, mode detection module and image quantization module, data storage and transmission module, etc. In this paper, the detailed design process and core code of each key module of the lower computer software are given, and some test results are given. In this paper, the upper computer software of FOD detection radar is designed and implemented by VC software. At first, the overall block diagram of the upper computer software is designed, and the cooperation flow of the upper computer software and the lower computer software is further designed, including the upper computer startup process, the serial port connection flow, and the upper computer sending work instruction flow. On this basis, the upper computer software is designed and programmed. The main module of the upper computer software includes serial communication module. Data processing module (including real-time target data processing and graphics data processing module, interface display module (including parameter setting module and drawing module). Finally, the software system is tested jointly. The system has been used to detect foreign bodies in an airport runway.
