[52N SWE] SPS and the SensorBus

cparent
Hello everyone,

Thanks to all those that have responded in the past. I just realized that all responses coming to me were going right into my spam folder!

Anyway, I am looking at connecting the SPS service to an instance of the SensorBus that I have stood up.  My question is, how does the SPS integrate with the bus and how is it intended to be used?  Using the SPS as it is, one would interface with it directly, and the SPS would task a sensor via the sensor plugin.  What happens when you introduce the bus? Theoretically you could bypass the plugin altogether and just have the SPS post tasking messages to the sensor bus.

What is the intended method of tasking sensors using the bus, particularly if they are mobile. (Could be a UAV or robot...)

Thank you
Chris Parent

Hi Chris,
The Sensor Bus protocol supports tasking of sensors. Therfore, a
so-called "PublishTask" message is included. Here is an example:
"PublishTask>sensor123>2010-09-29T18:30:00>move>Up>zoomFactor>1.5>..."

This message could be posted by an SPS to the Sensor Bus, to task the
sensor with ID "sensor123" (might be a camera) to move "Up" and set
the zoom factor to "1.5". Of course, those example task parameters are
only supposed to demonstrate the principal usage. The PublishTask
message is generic. Multiple task parameters can be carried.

To gain deeper insight, you might want to have a look at the G-WaLe
sensor adapter contained in the Sensor Bus project. It expects
commands from the sensor bus to task a G-WaLe sensor (a mobile water
level sensor; see also http://www.g-wale.net/).

Of course, the SPS has to translate calls of the "submit" operation to
the sensor bus protocol as well. Therefore, some kind of SPS adapter
for the Sensor Bus is needed. We've already started developing it,
however it isn't fully finished yet, since we've gotten distracted by
other business. It shouldn't take too much time to finalize it. Please
let me know if you are interested in this, so maybe we can join forces
on the development.

Cheers,
Arne
