Description
Technical field
The present invention relates to multi-channel data acquisition detection technique fields, specifically disclose a kind of multi-channel data acquisition state and refer to
Show lamp.
Background technique
Multichannel data collecting technology in industrial circle using more and more extensive, such as the automatic detection system on production line
System, the implementation of bridge, subway monitors system, therefore the accuracy of status display and validity is just during multi-channel data acquisition
It is particularly important.
At present in measurement and control area, common practices is to initialize to analog input card, before system starting by laggard
Row acquisition.In real data collection process, primary complete data acquisition, it is necessary first to guarantee board working condition it is normal,
Secondly the connection between confirmation collection terminal and tested end is errorless.But existing way can only examine the initialization of board
Survey, in testing engineering board working condition and cable connection status cannot accurately and effectively indicate, therefore can not be according to shape
State is prompted and is responded to user.
Summary of the invention
It is an object of the present invention to provide a kind of multi-channel data acquisition status indicator lamps, and which solve multi-channel data acquisition mistakes
In journey the problem of state instruction, the connection status in every channel is accurately obtained, system is determined according to state next
Walk work.
To achieve the goals above, invention uses a kind of technical solution below: multi-channel data acquisition state instruction
Lamp, every drive test examination mouth at the multi-channel data acquisition end are equipped with a control circuit board, and the control circuit board is in test lead
It is connected between tested end into an optocoupler, terminates a number input port DI in the induction of the optocoupler；By LED light pair
Ground seals in another digital output DO.
Further, the control circuit board is equipped with isolation circuit, amplifying circuit and filter circuit.
When data collection system is connected with equipment under test, optocoupler conducting, control optocoupler induction end is also also turned on, at this time
The end DI is pulled low, and the end DO exports 5V high level, and LED is lit.When data collecting card is started to work, pass through digital output DO
Low and high level is exported, control LED light starts to flash.According to testing requirement, increase isolation, amplification, filter on LED control circuit plate
The functions such as wave.
It lights, illustrates at this time all logical per LED light all the way after connecting the test cable of data collection system
The test cable in road is all connected with normally, if some LED light does not work, illustrates that the cable connection on the road is problematic.Initialize board
After start to be acquired, LED indication etc. starts to flash at this time, illustrates that acquisition state is normal at this time.
The beneficial effects of the present invention are: after adopting the above technical scheme, which solve during multi-channel data acquisition
The problem of state instruction, accurately obtains the connection status in every channel, and system is allowed to determine next step work according to state
Make, such as some work can be disabled in the case where cable does not connect.Work is indicated by the flashing of control instructions lamp
State, use are very clear.Implementation is simple and effective, low in cost.
Detailed description of the invention
Technical solution in order to illustrate the embodiments of the present invention more clearly, below will be to needed in embodiment description
Attached drawing is briefly described, it should be apparent that, the accompanying drawings in the following description is only the present invention in order to illustrate more clearly of this hair
Bright embodiment or technical solution in the prior art, below will be p- required for describing the embodiments or the prior art attached
Figure is briefly described, for those of ordinary skill in the art, without creative efforts, can be with root
Other attached drawings are obtained according to these attached drawings.
Fig. 1 is circuit diagram of the invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
A kind of multi-channel data acquisition status indicator lamp as shown in Figure 1, on the road the multi-channel data acquisition Duan Mei
It tests mouth and is equipped with a control circuit board, the control circuit board is connected between test lead and tested end into an optocoupler, in institute
The induction for stating optocoupler terminates a number input port DI；LED light is sealed in another digital output DO over the ground.It is described
Control circuit board is equipped with isolation circuit, amplifying circuit and filter circuit.The present invention can well solve multi-channel data and adopt
During collection the problem of state instruction.We devise one piece of control circuit by every drive test examination mouth at multi-channel data acquisition end
Plate.Control circuit board has sealed in an optocoupler between test lead and tested end, terminates a numeral input in the induction of optocoupler
Mouth DI；One LED light is sealed in into another digital output DO over the ground.When data collection system is connected with equipment under test
When, optocoupler conducting, control optocoupler induction end is also also turned on, and the end DI is pulled low at this time, and the end DO exports 5V high level, and LED is by point
It is bright.When data collecting card is started to work, low and high level is exported by digital output DO, control LED light starts to flash.May be used also
To increase the functions such as isolation, amplification, filtering on LED control circuit plate according to testing requirement.
The cable connection on the road is problematic.Start to be acquired after initialization board, this, which works as, connects data collection system
Test cable after lighted per LED light all the way, illustrate that the test cable in all channels is all connected with normally at this time, if certain
A LED light does not work, and LED indication etc. starts to flash when illustrating, illustrates that acquisition state is normal at this time.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
