【摘要】：随着社会的发展,嵌入式产品已经无处不在。嵌入式已成为了当前最热门、最具发展前途的IT应用领域之一。从事嵌入式的开发工作可以分为两类：一类是硬件开发工作,包括的内容有原理图、PCB到制板；另一类是从事软件开发工作,包括嵌入式操作系统、BSP、驱动和应用。航空发动机参数采集器就是为某发动机厂研制的一款嵌入式产品。目前使用的此类产品中,很多是国外进口的成品,或者是采购板卡进行集成,而本产品中关键部分全部采用了自研产品。其中,硬件中的CPU卡和采集卡、软件中的嵌入式软件和上位机软件,全部是自主开发。本论文研究的内容是航空发动机参数采集器中的嵌入式软件部分,它完成了从硬件板卡读取数据、存储数据,最后通过以太网将数据发送给上位机软件来进行事后分析数据。论文首先介绍了航空发动机参数采集器的软硬件平台,其中嵌入式操作系统使用了风河公司的VxWorks,硬件板卡使用自研产品CNS-C3-5200B和CNS-C3-AD,并对开发中使用的相关技术进行了介绍；其次分析和设计了嵌入软件与硬件之间的通讯和接口协议,分析和设计了嵌入式软件与上位机软件之间的通讯和接口协议；最后介绍了VxWorks操作系统在CNS-C3-5200B板上的安装,根据嵌入式软件的功能需求,对嵌入式软件进行了详细的设计,并最终实现了航空发动机参数采集器中的嵌入式软件。在本论文中,嵌入式软件的开发工作包括驱动开发和应用开发。论文对VxWorks环境下驱动程序的开发,应用程序的开发分别作了介绍,并对全系统测试进行了描述。最后,产品交付用户,得到了用户的认可。
[Abstract]:With the development of society, embedded products are everywhere. Embedded has become one of the most popular and promising IT application fields. The development work of embedded system can be divided into two types: one is hardware development, the other is hardware development. This includes schematic schematics, PCB to board, and software development. Including the embedded operating system BSP, driver and application. The aero-engine parameter collector is an embedded product developed for an engine factory. Many of the products used at present are finished products imported from abroad. The key parts of this product are all self-made products. Among them, the CPU card and acquisition card in hardware, embedded software and host computer software in software are all developed independently. The research content of this paper is the embedded software part of the aero-engine parameter collector, which reads the data from the hardware card and stores the data. Finally, the data is sent to the upper computer software through Ethernet to analyze the data afterwards. Firstly, the software and hardware platform of the aero-engine parameter collector is introduced. The embedded operating system uses VxWorksof Fenghe Company, and the hardware board uses CNS-C3-5200B and CNS-C3-AD. the related technologies used in the development are introduced. Secondly, the communication and interface protocol between embedded software and hardware are analyzed and designed. The communication and interface protocol between embedded software and host computer software are analyzed and designed. Finally, the installation of VxWorks operating system on CNS-C3-5200B board is introduced. According to the function requirement of embedded software, the embedded software is designed in detail. Finally, the embedded software in the aero-engine parameter collector is implemented. In this paper, the development of embedded software includes driver development and application development. The development of driver program and application program in VxWorks environment are introduced, and the whole system test is described. The product is delivered to the user and is recognized by the user.
