acquisition of data and put it in a table in regular order

Hello, experts OR

I would like to get some tips on how to put the data in a table in a regular sequence in FPGA

In FPGA, analog data of the sensor data.

1 data => allocate on index 1

2 data => allocate on index 2

...

I have given th => return to index i

Any advice is welcome.

Thank you.

You should read more carefully. We're talking FPGA. FPGA has to deal with arrays of fixed size. If you need to initialize the array and use then replace table subset or simply use a loop FOR.

Of course, it really depends on what the OP is really trying to do here. Maybe a little more context would help us to give you a better answer for your situation.

Acquisition of data and filtering on FPGA

Hi all

I have trouble to design a FPGA program for acquisition of data and filtering.

I have two NOR 9205 modules configured to work in terminal mode of DIFF, i.e. There are 32 entries this program must read every Ts seconds. (Ts is the time discretization, i.e. during the period of loop)

With respect to the digital filter, I implemented a possible simple filter with transfer function G (s) = 1 /(1+sT), which is part of the field of discrete-time equal to y (k) = a * u (k - 1) + b * y (k-1), where u is the original signal, and there is filtered signal. The coefficients a and b are equal to: a = 1-exp(-Ts/T), b = exp(-Ts/T), and T is the time constant of the filter (usually T > 5 * Ts).

The implementation of main program for the acquisition of data and filtering are:

This application is for the digital filter:

However, the problem is that this program cannot take the FPGA resources on cRIO-9114, and Yes, I tried to define the criteria of compilation for the area. I also tried to implement the multipliers in digital filter as lut and DSP, unfortunately without a bit of luck.

Because I don't have that much experience in programming of FPGA, someone has any suggestions how to improve this code to adapt existing FPGA resources?

Best regards

Marko.

Hey Norbert_B,

I managed to solve the problem. First, I changed the reentrancy of Preallocated incoming execution clone to not reentrant execution. As no reentrant VIs have States, I had to use the node of the feedback to the main VI to get u(k-1) and y(k-1). Another important thing is to choose Ignore FPGA reset method in the node of the properties of FPGA implementationfeedback, since in this case, the feedback node uses less resources.

Here is the new main program VI:

And here's the 'filter' VI:

Thanks for the help!

I need to get data from an RDBMS and put it in a file with EBCDIC encoding using ODI
I know how to get data and put it in the file using ODI, but do not know how to EBCDIC coding the file using ODI
Hello

Its very simple.

You must specify the encoding code in the JDBC URL of the server in the topology Manager data file.

For example,.

JDBC:SNPs:DBFile? ENCODING =

You can get your codes coding supported by ODI from here,

acquisition of data and processes in FPGA

Hello!

In FPGA, I am trying to acquire analog data (0 ~ 10V) with a specific time clock rising edge of each digital pulse encoder.

I went to get the data on the front, but I don't know how I'd keep th and i + 1 th data.

(Frequency of data is less than 250 kHz)

I have the cRIO-9074, NI 9411 (encode), NOR 9205 (module I),

data

1st, 2nd data, data 3rd 4th 5th 6th 7th... I-1 th, I e, i + 1-th... 1200 e (approx.)

I need every sum of two consecutive data data 1st + 2nd, 2nd + 3rd, 3rd + 4th, l - 1 e + i Thess,... th + (i + 1-th)... 1199 th + 1200 e (about)

On the process of two consecutive sum.

[i - 1 e + i th] / [a value] + [the other i e amount of different data acquisition] = 1199 set of data (up to 1200 th data)

and then

all data across data (data from 1199) will be worth.

Thank you very much!

All tips are welcome!

Sincerely,

Hyo

Looks like a simple feedback node will do the trick.

How to get only latest date and other columns in the table

Hello

Table
 
   id          name        date
  123        a             2/3/2010
  124        b            15/2/2010
  125        c             1/1/2010
  123        a             12/4/2010
  125        c             17/2/2010

It's a table, id, name, date here is the composite key.
I want to select id, name, and date so that date (e.g., 123 date 04/12/2010 be selected for the id) is selected for each id and each id and name should be selected once.
So, what will be its application?
Thank you

select
   id,
   name,
   date
from
(
   select
      id,
      name,
      date,
      max(date) over (partition by id, name) as max_date
   from your_table
)
where date = max_date;

Would do assuming you do not have duplicates (all 3 columns) in the table.

When I send a 5v of data acquisition, the voltmeter indicates 5V, but when I connect a "normally open" valve Parker for the acquisition of data, the voltage decreases automatically a.14 V. It seems to be grounded. Why is this happening?

We send 5v data acquisition using a voltage generator. Hook us it up to a voltmeter and see 5V. When connect us the generator voltage to a valve "normally open" parker, the voltmeter indicates .14V. It seems that when we connect the two sons of the valve for the voltage generator, the son act as pattern. We want to control the voltage flowing to tap through Labview. We checked the wires to the valve and they work very well, because if we send a constant 5V since the acquisition of data and put ashore, she, the voltmeter indicates 5V. Someone knows why the son act as pattern and low blood to .14V?

nsatpute wrote:

Our data acquisition is NI USB-6259. The valve requires only a 5V max and our DAQ provides up to 5V. However, after connecting the valve to the acquisition of data, the grave tension to almost 0. We start from the principle that the son somehow act as the reason, but we are not sure if this is the case.

The question here is not how much voltage the valve wants, it's the current needs of the valve. The 6259 can put only 5mA via an analog output. Your very likely tap needs much more than that. If you need to add in an amplifier circuit that can supply more current to operate your faucet.

How to connect dwyer SERIES 629 differential pressure transmitter to the acquisition of data 9219 and read the signal?

Here is my sensor
Pressure sensor

Here's the DAQ data sheet:

ACQUISITION OF DATA NOR 9219

Here are my issues:

First of all I don't know what is LO and HI exactly in the DAQ 9219 material.

Second, I don't know what pin code I should connect the DAQ sensor signal wire. PIN 4 or 5 pin? The sensor has three pins, and I guess I should connect the other two wires to the power supply.
Thirdly how to calibrate the sensor. In labview choose voltage in the wizard?

I'm pretty new in this acquisition of data and I need your help.

Thank you

Hi SilasIII,

Hmm well 3 sons are probably on the ground, the power and the return signal. The datasheet for the sensor says:

First of all, you need to know which model you have (4-20mA, 0 - 5V or 0-10VDC). HI refers to the return signal, LO essentially means the land of the food that feeds the sensor. Then, you must get the 13-30 VDC supply. I don't think this should be too complicated and can be a simple wall DC power. You can learn how to create a custom in DAQmx scale. I hope that this is a starting point.

Kind regards

Acquisition of analog and video synchronized

Hello experts tiara,.

I am curious about this example Diadem DAC:

http://zone.NI.com/reference/en-XX/help/370858M-01/explonl/explonl/explonl_dac_video/

He claims to be able to acquire analog and video synchronized. Anyone can determine how to properly synchronize these two data flows are? Because it is a desk, probably Windows machine and no trigger material between video and analog devices, I'm guessing that the two are, at best, on +-1 second.

Can anyone solve this problem? I see in the manual use tiara (here) that NEITHER has done some work in order to study how the clocks are accurate in Diadem. And they even mention a few points of 100 msec. But I don't really trust this number when it comes to acquiring analog and video data simultaneously.

Thank you, John

Hi John,.

You ask an interesting question, and I had contact with the developer of R & D responsible for this service and received an explanation on his part on the works of this feature.

The target application for this specific feature is not for use cases where the exact synchronization between the measurement and data acquisition are required (i.e. a crash test of vehicles with more than 1000 frames / second video recording). This feature is implemented for users who wish to have the possibility to use webcams to get insight into what their machine or test do any recoding data at the same time. We should ask this 'parallel acquisition data and video' and not 'synchronous acquisition' - which suggests that it is a way to ensure that the data and the video are actually synchronized during the acquisition process. The original entered German aid system speaks 'parallel' instead of 'synchronous' acquisition, the English translation incorrectly uses the word 'synchronous' instead of 'parallel '. I contacted our documentation team to clarify this part of the help system.

Accurate synchronization to achieve, especially between multiple streams of data acquisition and a camera, the application must use frame grabber hardware - hardware specifically designed to support the capture video or image.

This is how DIAdem DAC addresses this type of application, I hope this information is helpful to you and others to this feature:

Tiara DAC is a top priority on the acquisition and the release of the data to and from data acquisition equipment. The video recording feature is less of a priority and is not controlled by tiara constantly. The video recording process is triggered as closely as possible to the data acquisition process. The current local time stamps of two triggers (data and video) is registered allows us to determine the exact time for the two signals of reading according to DIAdem, i.e. If there is a delay in the start of video recording, is considered for reading in MODE of DIAdem.

Our tests with made with a camera (not multiple, which is supported by MODE of DIAdem) and data acquisition equipment NOR (not several devices, which is also supported by DIAdem). In these tests, that we have seen the video and data were generally synchronous within some frameworks (no real 100% synchronicity) - which was quite thin which this solution based on USB low-cost camera technology was designed for. It is generally better than +/-1 second depending on the application, but also synchronized to the millisecond like material systems would be able to achieve.

There are several factors that influence the results of the tests carried out in this area of application: PC hardware (CPU, RAM, disk system), the tasks of measures, other software running on the computer chassis, the camera and the framework, software drivers, etc.. There are too many variables beyond the control of tiara that can influence the synchronicity of the acquisition of data and images based on the software only, so true synchronicity can be achieved using equipment designed for this purpose.

I hope that clarifies the DIAdem DAC functionality a little better. Thank your for having pointed out the misuse of the book 'synchronous' in the help system, going as fixed for the next release of DIAdem. Please let us know if you have any other questions.

Best regards

Acquisition of data reading zero intermittently

I use 3 analog inputs of an acquisition of data USB-6009 to monitor and record the temperatures of my system. This running VI constantly perform 1 read per second and periodically saving the values drop. Everything works very well for a few weeks or even months, until that data acquisition shows suddenly have a value of zero. unpluging the acquisition of data and by him plugging back in solves the problem. Therefore, I assume that this is due to the DAQ or maybe the USB communication being refreshed power cycle that I get the correct values again. Any ideas on how to test for the cause of this problem or preventive measures, can I take?

I was the closing of thought and could help restore communication at the end of each day.

Oh, and I'm using LabVIEW 2010 on Windows 7.

Disable the 'power save feature' Windows 7 where it randomly disables your USB hub. Go to Device Manager and go to USB hubs then the power settings.

There are several ways. One is to get the date of the php time() function and use it in your insert statement. Another is to use the MySQL CURDATE () function. But probably the easiest and best are simply set the default value for the column of date / time than the current date/time and exclude it from the insert statement. No required code changes.

For the date, I tried < cfqueryparam value = #createodbcdate (thedate) # cfsqltype = 'CF_SQL_DATE' maxlength = null "23" = "yes" > and got NULL in the table.
For once I tried < cfqueryparam value = #now () # cfsqltype = "CF_SQL_TIME" maxlength = null "23" = "yes" > but the date part of the datetime value is 1970-01-01.
In the table, these column types are datetime.

As its name suggests, cf_sql_date inserts the date. Any time value is truncated. To insert the date and time using cf_sql_timestamp.

For the date, I tried<>

value = #createodbcdate (theDate) # cfsqltype = 'CF_SQL_DATE '.

MaxLength = "23" null = "yes" > and get NULL in the table.

It's null = mean 'yes '. It loads CF to ignore the 'value' and insert a NULL value instead. Use it only if that is the intent.

Producer/consumer or master/slave, acquisition, control, analysis and recording of data

Hi all

I have NEITHER cDaq-9188 and its modules NI 9214 (thermocouple), NI 9203 (HAVE current) and NI 9263 (AO tension). I need to measure the temperature and pressure, and according to these data, I need a frequency converter to drive a compressor control. I've developed acquisition, analysis and recording program by the use of the state machine, the design of producer/consumer model and I have no doubt about their. They all work very well. Now, I need to add a control program in their. The problem is that I need to check the compressor with feedback from temperature data permanently, but I do not necessarily all the data acquired and permanently from the results of the analyses. For example, I need to record data once in 30 seconds. Which model desing should I use for this task?

Edit: I was not able to find examples of advanced program relevant to the design of master-slave model. If you know where to find them, could you write in this thread please?

The declarant buffer not data. Do only the queues. A new notification replaces the old value if she is ever read or not. You would be loss of data with the notifiers if the loop of consumers with a notification utility cannot keep up with the data that they fade.

What I show all the data buffers through the queue in the loop of the producer. The queue of the consumer removes all data and do stuff with him (such as logging) if the elapsed time is over. What is the problem with that? That is what for (imstuck) described in his message.

The other alternative is that you put the timer into the loop of the producer. Have the Boolean value TimehasElapsed drive a deal structure this place only the data if the time is over. In this case, only some data gets queued, and consumer loop removes all data as it gets and it opens a session.
