Analog outputs can be used in road and rail tunnel applications as well as crane applications.
You can get horizontal and direction data with
the parameter aout_map. The aout_map parameter defines how analog output signals are used. WMT700 provides
the following analog outputs:
- aout1 for wind speed data
- aout2 for wind direction data
| Parameter | Definition |
|---|---|
| 0 | aout1, wind speed aout2, wind direction (default) |
| 1 | aout1, North-South, x component aout2, West-East, y component Typically, only the component x is used. |
| 2 | aout1, wind speed aout2, wind speed alarm A digital output: hi when wind speed > aout2_0 |
The following table shows the relationship between polar representation and the x and y vector components.
| Wind speed | Wind direction | x component | y component |
|---|---|---|---|
| 1 | 0 | -1 | 0 |
| 1 | 90 | 0 | -1 |
| 1 | 180 | 1 | 0 |
| 1 | 270 | 0 | 1 |
