Small aircraft often used RS485 bus. But with the complexity of the small aircraft's subsystems increase and the progress of field bus technology
CAN bus systems in small aircraft use more and more widely. How to record real-time flight experiment data on the small aircraft's CAN bus and provide test data for reproducing the process of a small aircraft flying is very important. This paper presents a design method of signal acquisition device
it can be used for small aircraft flying field experiment. 2010 IEEE.

The common bus on bus control is RS232. With the development of field bus technology
field bus technology is widely used in data recorder. How to real time record the data of field bus in the experiment and provide the test data for process reconstruction is a very important problem. This paper introduces a kind of data acquisition and storage based on field bus. Its core design is C8051F040 microprocessor and SJA1000
a widely used field bus controller. This paper presents the basic constitution of this field bus data recorder and set forth its hardware and software. This field bus data recorder field bus real-time gathers the information and storage data on the CF card. The result of the experiment shows the system is highly reliable for data acquisition and storage
which should have abroad application prospect for data record experiment. 2010 IEEE.

In order to achieve the dynamical detection and real-time analysis of the movement status of the magnetic fluid
according to the difficulties of the detection of the magnetic fluid
established a high-speed acquisition and processing system of laser speckle signal on the magnetic fluid. First of all
the FPGA (EP2C8T144C8N) drived the linear array CCD(TCD1501D) to scan in the corresponding time sequence given by the computer
collected the laser speckle interferometric image in rapid change on the surface of the magnetic fluid
which followed the movement of the magnetic fluid
and the signal collected by CCD was converted into the digital data through the high-speed A/D convertor and stored into the internal buffer FIFO of the FPGA
whose width and depth were designed by the user as required. Then
the FPGA sent the digital signal of the laser speckle interferometric images into the computer through the USB2.0 highspeed differential bus
whose transmission rate can reach 480Mb/s in theory. Finally
the distribution of the laser speckle on the magnetic fluid was messy and random
which carried certain information about the surface of the magnetic fluid
based on the theories of the statistic correlation and the subdivision of images
analysing and processing the laser speckle interferometric images
indirectly got the movement status of the magnetic fluid under the electromagnetic field. The experimental results show that: the High Speed Acquisition and Processing System has the advantage of full-court
non-contact
non-invasive
high-precision and high reliability and so on. The detection resolution of high speed acquisition and processing system is superior to 1m and the sample rate is 3Msps
which basically meets the requirements of the magnetic fluid movement state detection. 2009 SPIE.
