Measured (almost) does Air Traffic Control
Monitoring weird hardware reliably
The new Danish Air Traffic Control system, CASIMO,
prompted the development on a modular and general
software platform for data collection, control and
monitoring of "weird hardware" of all sorts.
The talk will present the "measured" daemon, and
detail some of the uses it has been put to, as an,
admittedly peripheral, component of the ATC system.
Many "SCADA" systems suffer from lack of usable
interfaces for external access to the data. Measured
takes the opposite point of view and makes real-time
situation available, and accepts control instructions
as ASCII text stream over TCP connections. Several
examples of how this can be used will be demonstrated.
Measured will run on any FreeBSD system, but has
not been ported to other UNIX variants yet, and it
is perfect for that "intelligent house" project of
I believe I gave a WIP presentation of this about
