OBJECT: Drive
|
||||
DESCRIPTION:
|
||||
This object provides an interface to the elevation/azimuth
|
||||
drive system(ECA).
|
||||
THEORY OF OPERATION:
|
||||
This object encapsulates the turret drive. The object provides
|
||||
an interface to control the turret drive. A method is provided
|
||||
to set the azimuth and elevation rate of the drive. Methods are
|
||||
provided to request the drive to run in stabilized or power mode
|
||||
and set the drive speed to high or low. A method is also provided
|
||||
to allow for drift adjust.
|
||||
|
||||
This object also tracks drive system on hours. It gets the hours
|
||||
from the EEPROM data, allows the hours to be set, updates the
|
||||
hours via the activation and deactivation of the drive, and
|
||||
provides access to the hours.
|
||||
|
||||
The object also provides methods to access azimuth and elevation
|
||||
displacement, and methods to process changes in the hardware
|
||||
discretes drive on, stabilized mode, thermal fault and fault.
|
||||
|
||||
The object also provides methods to enable and disable
|
||||
both the remote and turret power interlocks which determine if
|
||||
the drive can be driven by the remote or turret handstation
|
||||
respectively.
|
||||

||||
ATTRIBUTE DESCRIPTIONS:
|
||||

ATTRIBUTE: Azimuth_displacement
|

DESCRIPTION:
|

This attribute represents the current azimuth displacement
|
||||
of the turret.

OBJECT: AVDAS
|
||||
DESCRIPTION:
|
||||
This object collects various values from other objects in the system
|
||||
and outputs the values in a message on a serial interface. The message
|
||||
can be read and used as diagnostic information.
|
||||
THEORY OF OPERATION:
|
||||
This object contains a Server task which periodically collects
|
||||
diagnostic values from other objects in the system and outputs the
|
||||
values in a message on a serial interface. The diagnostic values
|
||||
collected and formatted reflect system status.
|
||||
NOTES:
|
||||
The following engineering note consists of a chart to aid in the
|
||||
decision making process of whether the AVDAS should reflect System
|
||||
status or Switch status. As it is right now, it was decided to
|
||||
reflect System status.
