anemometer

Purpose:

Collect and process data from the Applied Technologies anemometer, updating wind speed and temperature variables.

Enter:

anemometer &

Where:

N/A

Example:

anemometer &

Notes:

No command-line arguments are required. The ‘&’ runs the program in the background as a service.

This program starts automatically with CyFlex and requires the configuration file ‘/specs/AT_ANE.cfg’. It creates real variables for wind speeds in U, V, W directions (in meters per second) and temperature (in degrees Celsius). An event is set if communication is lost.

This command is normally placed in /cell/go.scp so that it starts automatically when CyFlex is started.

A copy of the AT_ANE.cfg file is located in cyflex/specs.def at CTC and in /specs.def at “cmxnode1”

The following real variables will be created:
variable            units           desc.
wnd_spd_u    m/sec    The value of the U direction wind spd
wnd_spd_v    m/sec    The value of the V direction wind spd
wnd_spd_w   m/sec    The value of the W direction wind spd
wnd_temp      deg_c    The value of the wind temperature

The Applied Tech. anemometer streams 4 values. They are the wind speed in three directions (x,y, and z directions) and the temperature.

An event called “anemometer_comm_loss” is created and set if the communication from the device stops. The event can be used in er_specs, gp_test, etc., to provide a mechanism to email support personnel.
