Abstract
The invention relates to a multichannel data collection system. The multichannel data collection system is characterized by comprising multiple sensors, multiple signal conditioners, an analog multiplexer, an A/D converter, a preprocessing unit and an industrial personal computer. Each sensor is connected with the corresponding signal conditioner, the signal conditioners are connected with the analog multiplexer, the analog multiplexer is connected with the A/D converter, the A/D converter is connected with the preprocessing unit, and the preprocessing unit transmits data to the industrial personal computer and is composed of a processor, a frequency converter and a filter. The multichannel data collection system has the advantages that the multichannel synchronous data collection system is adopted, signals of all channels at the same moment can be collected, and data collection efficiency is high.
Description
Technical field
The present invention relates to data acquisition technology field, specifically a kind of multichannel data acquisition 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 in continuous enhancing. In modern signal processing system, in order to analyze system better, 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 neither be significantly high.
Summary of the invention
Not enough for above-mentioned prior art, the present invention provides a kind of multichannel data acquisition system.
Multichannel data acquisition system provided by the invention is achieved through the following technical solutions:
A kind of multichannel data acquisition system, it is characterized in that: include multiple sensor, multiple signal conditioner, multiway analog switch, A/D converter, pretreatment unit, industrial computer, described each sensor connects with corresponding signal conditioner respectively, described signal conditioner connects multiway analog switch, described multiway analog switch connects A/D converter, described A/D converter connects pretreatment unit, and described pretreatment unit sends data to industrial computer.
Described pretreatment unit is made up of processor, converter, wave filter.
The invention has the beneficial effects as follows: adopt multi-channel synchronous data acquisition system, it may be achieved gather the signal of each passage of synchronization, and the speed of data acquisition is high.
