Hardware Research On The Measurement System Of Ring Laser Resonant Cavity

With the development of society, embedded products have become ubiquitous. Embedded has become to one of the most popular, the most promising IT applications. In embedded development work can be divided into two categories:one is the hardware development work, including the contents of the schematics, PCB to the system board; the other is engaged in software development, including embedded operating system, BSP, driver and applications. Aero-engine parameter collector is an embedded product developed by an engine plant currently using these products, many imported finished products, or procurement card integration, a key part of this product all self-development products. Among them, the CPU card and capture card hardware, software, embedded software and PC software, all the self-development.The content of this thesis is part of the embedded software in the aero-engine parameter collector, it completes the read data from the hardware board stored data, data is sent via Ethernet to the host computer software to carry out post hoc analysis of data.The paper first introduces the aviation engine parameters acquisition hardware and software platforms, embedded operating system used Wind River's VxWorks hardware board using the self-study products of CNS-C3-5200B and CNS-C3-AD, and the development ofthe use of technology; analysis and design of embedded communications and interface protocols between software and hardware, analysis and design of communication between the embedded software and the host computer software and interface protocols; the VxWorks operating systeminstallation of CNS-C3-5200B board, according to the functional requirements of embedded software, embedded software detailed design and, ultimately, the embedded software in the aero-engine parameter collector.In this paper, the embedded software development, including driver development and application development.Paper in VxWorks driver development, application development were made presentations, and system-wide tests are described. Finally, the product delivered, the user acceptance.
