Solution to challenging sampling requirements
I wanted to share with your users a pretty simple solution to what we thought was going to be a difficult sampling control problem.
We recently finished a project which required some unusual sampling schemes for Nortek Continental Profilers. In this application, our customer required 2 minutes of 1 Hz sampling, record each individual ping, then shut down for 2 hours before repeating the cycle. For each sampling event, they required that a new data file be created. Quite a unique requirement for the Nortek software to handle.
Our solution was to use a fairly common program called “Advanced Task Scheduler” (ATS) to control the start and shut down of the profiler control software (Continental.exe).
Here is what we have done:
In Continetal.exe
Create a deployment file (project.dep), sampling and profile interval at 1 sec. Specify disk destination for data, select ASCII format
In Advanced Task Scheduler.exe
Create a task to launch Continental.exe (time = 00:00:00)
Use command line arguments -s -f project.dep (start sampling, output data to disk file, deployment file name)
Create a task to stop sampling / Continental.exe (00:02:00)
Create a task to respond to the "Stop Data Collection?" prompt (00:02:05)
Repeat cycle (02:00:00)
Pretty simple. We have tested it out and it works well. Individual 1 Hz pings are recorded by Nortek software as expected, each 2 minute file is named by date and time. We also tested using Nortek Aquadopp Profilers, same successful result.
The key is to use task scheduling software to control profiler software.
I hope that someone may find this helpful.
