There are a variety of signals in human social life and production, as well as in nature, and many signals are critical to human life and production, so it is important to be able to collect and process these effective signals effectively. Signal acquisition system is used to achieve this function, through the acquisition of the signal processing, remove the interference signal, and then converted into digital input to the control device for some processing of the signal, and finally processed data obtained after the results transmitted to PC display or to do further processing.
This paper is the work of multi-pump test stand of the signal acquisition and control system design, the specific content is as follows:
Chapter 1: introduces the introduction of aircraft hydraulic system, the new large-scale passenger aircraft hydraulic system program, signal acquisition and control system significance, and research status.
