Flight Test Validation System Simulation Siganl Source Bus Interface And Driver Design

In recent years, As China’s comprehensive strength continues to improve,Chinese commercial aviation market has become increasingly large,But the large commercial aircraft market has been occupied by foreign absolute share several major aircraft manufacturing companies,So in order to break the monopoly of the revitalization of the country’s aviation industry,the development of China-made large aircraft for the commercial aviation industry in our country is more urgent.In the process of development of large aircraft whose flight validation process is extremely complex and lengthy.This needs to be a unit of its research team as an analog signal source subsystem verification system under test, the subsystem is responsible for responding to flight test aircraft control platform and simulation parameters at various sensors in real flight.This topic is in the development of this analog signal source subsystem expanded background.This article focuses on the content of the work for the development of an analog signal source system bus interface and its driver.The bus interface is connected to an analog signal as the source control software source subsystem to communicate with the local board in the subject of simulation work.This article can be divided into five parts,This paper identifies the first part, the communication interface using the PCI bus interface card joint local bus mode according to the subject needs to connect the analog signal source board and local test control software, signal type definition local bus communication protocol methods of work, including local bus to mount local analog signal source board, so to simplify the communication complexity,The second part introduces the subject of how to carry out the process of designing a hardware platform based on FPGA PCI communication interface cards, in this part of the detailed description of the hardware board design process all the details,The third part in the above hardware platform based on the completion of the PCI interface Verilog soft-core-based designs in this section describes in detail the communication interface PCI soft-core design philosophy and its simulation, debugging and verification methods,The fourth part introduces the WDM driver development DriverStudio3.2 the PCI communication interface card Windows xp environment and MFC-based application design based on tests in this section details the PCI-driven design ideas and principles and the board function SignalTap II logic Analyzer analysis of test results;Finally, Part V Theoretical and experimental test results of actual communication interface board for PCI hardware and software package has made the speed and power of analysis.As used herein, the bus interface is designed for communication transmission link subject the entire analog signal source subsystem, plays a vital role.After continuous access to the configuration parameters of the test board, the board is now able to complete more stable and testing operations between applications, I/O space and memory space access operation, interrupt function.These basic functions of communication provides a bridge between the analog signal source systems follow the local board and the local analog signal source software testing platform for the successful development of the whole system has a very important role.
