Abstract
The invention relates to a data acquisition system, which is characterized in that the data acquisition system comprises a plurality of sensors, a plurality of signal conditioners, a multipath analog switch, a sampling and holding module, an A/D converter, a pretreatment unit and an industrial control computer. The sensors are connected with the corresponding signal conditioners respectively; the signal conditioners are connected with the multipath analog switch; the multipath analog switch is connected with the sampling and holding module; the sampling and holding module is connected with the A/D converter; the A/D converter is connected with the pretreatment unit; and the pretreatment unit transmits data to the industrial control computer. The multichannel synchronous data acquisition system can realize acquisition of signals of channels at the same time, and data acquisition speed is high; and through the arrangement of the sampling and holding module, digital signals obtained after A/D converter are allowed to reflect the original analog signals correctly.
Description
Technical field
The present invention relates to data acquisition technology field, specifically a kind of data collecting 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 data collecting system.
Data collecting system provided by the invention is achieved through the following technical solutions:
A kind of data collecting system, it is characterized in that: include multiple sensor, multiple signal conditioner, multiway analog switch, sampling maintenance module, 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 sampling and keeps module, described sampling keeps module to connect 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；Sampling is set and keeps module, it is ensured that the digital signal after A/D changes can correctly react original analogue signal.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Detailed description of the invention
