The Simultaneous Acquisition of the Mixed Vehicle-Carrying Signals Based on the CompactRIO

Abstract

In order to realize a simultaneous acquisition of the mixed vehicle-carrying signals, this paper put forwards a new acquisition system that synchronous controls the digital IO module, the vibration-and-noise module, the electrical pressure module, the temperature-measuring module, as well as the CAN module, under the mode of FPGA, which is based on the embedded platform CompacRIO, and it could also be controlled by both PC and PDA. The operating procedures of this system are highly reliable and compatible, specifically designed to be people-oriented. This paper gives a full introductions to how the multi-mixed signals are simultaneously collected, the deepening of the FIFO on FPGA, and how it could be controlled by PDA. Finally, the efficiency and stability of the system would be proved through the practical pressure tests of data-acquisition.
