Changes
Key: Additions Deletions
For AV-Trend Sitesthat are on TCP/IP connections, you may use the AV-Trend Sync capability to automatically synchronize configuration and data between the two computers and poll the site data.
For sites that are still on modems, this sync capability is not available, so you would continue with the Digi-Trend method for collecting data (e.g., poll the logger directly). However, we still need a process to manually carry annotation and logbook entries from the site computer back to the central. For this, AirVision 2.3 provides an export/import function.
Note that for this process to work, the Site and Parameter names in the AirVision and AV-Trend systems *must* match exactly. This is the key used to line up the data.
Server Side
First, create a directory on the AirVision server for files to be dropped for processing. For this illustration, we will assume a shared directory and folder which appears to the server as “x:\IncomingAVT”
Secondly, we will add a Scheduled Command Line Task to the Task Scheduler to run the minute data import function on that directory. Use Configuration Editors->Task Scheduler and select “Scheduled Command Line Task.” Set an execution interval that you would like (say, hourly), give the task a descriptive name (“DigiTrend Minute Import”) and put in the following for the executable name and command line arguments:
Executable:
“C:\Program Files\Agilaire LLC\AirVision Server\TableImporter.exe”
Command Line Arguments:
/D x:\IncomingAVT /X
Obviously, you would replace the appropriate import in the example with your directory path.
AV-Trend Site Computer Side
Similarly, you will create a scheduled command line task to export the files to a particular directory, or drive number (e.g., a USB drive):
Executable:
“C:\Program Files\Agilaire LLC\AirVision Server\TableExporder.exe”
Command Line Arguments:
/V ExportLogBookEntry,ExportAnnotation /D C:\temp\Export /L 30D
/V = table names
/D = destination directory
/L = lookback period (number of days to export). It is OK to have import/exports overlap, so pick a larger period than your site visit frequency.
