retrieval ecg signal

[khaled377]

hello everyone,

 Actually, I have sent the signal of DMM that's a dynamic data from the client to the server and, that was good , the signal  is received by server as it is sent from the client but now I need to send the ecg signal from client ecg.vi to server ecg.vi that are attached below but it is received badly and I attempt to solve this problem but I have failed so if anybody can help with this and thank you very much.

Note:I  just changed in ecg client .vi , the DMM signal by the simulate ecg only and anything in the server.

Look at your small Express VI in the Client VI that converts the dynamic data type to an array.  It is set to convert to an array of scalars (most recent value) which means only 1 element gets sent.  You want Convert to a 1-D array of scalars - automatic or single channel.

Hi khaled,

  For programming ,you can browse the examples data server.vi and data client.vi....There in examples....server willl be transmitting data and client will connect to the server and get the data..In think in your program also you need to interchange the client and server functions...where server will be transmitting the ecg data and client will be collecting the data....

Thanks and regards,

Hello,thanks for your reply. Actually, I tried all choices  mentioned with the small Express VI in the Client VI that converts the dynamic data type to an array but it doesn't work so I have to think another way but I don't know how?

And for the data client and server VIs my program is almost the same . (I have tried them but this give me the same result ).

 so if you can help me and thanks again.

Other things you need to do.

1.  Use the same port number in both programs.  Right now they are different.

2.  Take out the wait function in the server.

3.  Autoscale the X axes on the charts in both programs.  The server chart has a different range, and the fact is is zoomed in more makes it look like a different signal.

Hi Revens,

I tried what you told me to do but it doesn't work. what I am thinking about is the way to convert the ecg signal before sending it and retrieved it in the server side .

  thank you.

How is it not working?  Give us some details.

I was able to do all the steps I told you and everything seemed to work just fine for me.  What conversion of the ecg signal are you talking about besides the conversion from the blue dynamic wire to the array?

Post your latest VI's that have incorporated all the changes you've made since the last time so we can see what else might be missed.

Well you start with a heart. Then you make an ECG amplifier. Connect the ECG amplifier to some data logging equipment. Write some code in Labview. And then you are at the end of line. Since you are from Norway I selected the simple explanation. But perhaps you can fill in with some more info. What are you trying to make. Is some sort of school project. Because ECG equipment may be Potential hazardous. But if you are under guidance of some trained person. It will be more safe. By the way is not school in Stavanger for people who want to work with med-tech equipment 

And please do NOT hijack others threads. Start You own(just do it). This thread is not very related to your problem. Besides it is sloved
