Description

There is the data acquisition unit that improves structure

Technical field

The utility model relates to data acquisition applied technical field, is specifically related to a kind of data acquisition unit that improves structure that has.

Background technology

In the R&D process of medicine, not only will process a large amount of clinical numerical information, and a lot of clinical picture is difficult easily with numeral description, such as X-ray line chart sheet, cardiogram etc., now just need to be to its clinical picture digital simulation; So in actual R&D process, the situation that often appearance should gather simulating signal again to digital information, must be used two kinds of collectors ability practical requirement.And existing data acquisition unit can not well be realized on line operation function, each data acquisition unit is an isolated node, and extended capability is poor; When needs, carrying out each data acquisition unit of point of digital signal or collection of simulant signal is to need independent path to be connected the waste that has caused resource with host computer, no matter be in R&D work or production run, these problems are to be all badly in need of solving.

Utility model content

The technical problems to be solved in the utility model is, overcomes deficiency of the prior art, and a kind of data acquisition unit that improves structure that has is provided.

For technical solution problem, solution of the present utility model is:

A kind of data acquisition unit that improves structure that has is provided, comprises digital collection module, analog acquisition module, power module, human-computer interaction interface, ADC module, DAC module and fieldbus module; Described digital collection mouth is comprised of the parallel port of digital collection module, and fieldbus module is connected with digital collection module by bus interface, and described digital collection module output terminal is also connected with human-computer interaction interface; Between digital collection module and analog acquisition module, be connected with ADC module and DAC module; Described power module is connected with analog acquisition module with digital collection module respectively by power supply interface; Described analog acquisition module comprises MCU and analog data acquisition unit, and described analog data acquisition unit output terminal is connected with MCU input end; Described analog data acquisition unit is provided with an analog acquisition mouth.

In the utility model, described ADC module is converted to discrete digital signal the simulating signal of the continuous variable after the collection of analog acquisition module processing and flows to digital collection module; The described DAC module i.e. digital signal of the discrete variable the collection of digital collection module and after processing is converted to continuous simulating signal.

As a kind of improvement, described fieldbus is CAN bus.

As a kind of improvement, described human-computer interaction interface comprises LCDs and keyboard, is convenient to carry out to data manipulation and shows observation.

Compared with prior art, the beneficial effects of the utility model are:

1, the utlity model has a plurality of digital collection mouths, a plurality of analog acquisition mouth and fieldbus, data acquisition function is powerful, can meet many-sided demand;

2, secondly, the utility model can also be realized online use by fieldbus, and data rate is fast, can carry out on-line data acquisition to a plurality of data collection points;

3, then, the utility model is also provided with human-computer interaction interface, comprises keyboard and LCDs, and the data that collect can be reacted intuitively in LCDs and can be realized storage to data by keyboard, the operation such as leave out, practical;

4, last, the utility model can be expanded acquisition port according to demand, and extended capability is strong.
