Abstract
The invention discloses a multipath data acquisition system, comprising a plurality of sensors, a plurality of amplifiers, multiple paths of analog switches, a sampling maintaining module, an A/D converter, a pre-processing unit, and an industrial personal computer; each sensor is connected to the corresponding amplifier; the amplifiers are connected to the multiple paths of analog switches; the multiple paths of analog switches are connected to the sampling maintaining module which is connected to the A/D converter; the A/D converter is connected to the pre-processing unit; and the pre-processing unit transmits data to the industrial personal computer. The multichannel synchronization data acquisition system can collect signals of various channels at the same moment and has high data collection efficiency. The arrangement of the sampling maintaining module guarantees that the digital signal converted through the A/D converter can accurately reflect the original simulation signal.
Description
Technical field
The present invention relates to data acquisition technology field, a kind of multi-path data acquiring system.
Background technology
Data acquisition technology is widely used in the fields such as communication, radar, Aero-Space, industry.Along with developing rapidly of microelectric technique and computer technology, the performance of data collecting system is improving constantly, and function is constantly strengthening.In modern signal processing system, in order to preferably analyze system, generally require while gathering key signal and synchronously gather some coherent signals.Previous multichannel time-sharing multiplex data collecting system can only realize circle collection multiple signals, and can not realize gathering the signal of each passage of synchronization, and additionally the speed of data acquisition is not the highest.
Summary of the invention
Not enough for above-mentioned prior art, the present invention provides a kind of multi-path data acquiring system.
The multi-path data acquiring system that the present invention provides is achieved through the following technical solutions:
