Data Management System Panels

These panels are dedicated to control and monitor the data management system (DMS). The operator should not need to use these panels during nominal operations.

To use any of the command objects, colored in gray, the operator must first have command authority of the DMS system. Therefore to use the DMS Reset button on the DMS Summary Panel the operator must first have the command authority of the DMS system.

DMS Summary Panel

This panel allows the operator to monitor and reset the main and monitor processors on board.

DMS heartbeat indicators and text boxes

The main and monitor CPUs issue a periodic heartbeat by sending out an incremented timer. The text box displays the last heartbeat index. The indicator is a short cut which displays green when the heartbeat is being received, red when an update has not occurred for some TBD time.

DMS Reset Button

This button resets both the main and monitor CPUs.

DMS Command Authority Panel

Command authority is used to ensure only one operator is controlling a particular system. Each of the five major systems are listed. This panel is used to monitor who currently has command authority of each system and can be used to override and forcibly change a systems command authority status.

Status Indicator and Menu

The menu is used by the operator to forcably change the command authority of a particular system. Once clicked a menu will appear showing all control stations capable of having command authority. If one of those options is chosen, a request to the command authority module will change authority, removing authority from the previous owner an authorizing the new owner. Two other menu items are available:

Empty- This option removes the current user of command authority. Any operator is free to ask for command authority.

Blocked-This removes the current user of command authority and will not allow anyone else to request for authority. The only way to change authority is by using the status menu again and selecting a control station or empty option.

The indicator is used to show the progress of the request. Due to time delay a request could take some time to be completed, this indicator turn dark blue when the request is initiated. When the request is confirmed the indicator returns to the background color. Red indicates an error occurred.

Control Stations List

This scrollable list shows all the control stations which can request or be given command authority.


DMS Error Handler Panel

This panel is used to help the operator shift through different error, warning, and information messages. Every message is logged on this panel. The operator uses the heading menus on the top to sort and filter messages. The objects on this panel do not send commands, therefore, the operator does not need command authority to use this panel.

Error Browser

The large gray area displays all the error, warning and information messages logged by Ranger or the control station. This scrollable list allows the operator to select on a particular message to see greater detail.

Filter Menus

Along the top of the browser are sever heading/menus. Each menu allows the operator to filter out or sort the logged messages according to each heading:

Time - this is the local time that the computer logged in the message. The default is to sort by time with most recent messages on top.

Error Type - This is the severity of the message: Safety Error, Error, Warning, Info.

Error Code - This is the id of the message. (Ex Id = 12 is a position boundary management violation)

Where - This names which computer system reported the message.

Module - This is the name of the specific software module that reported the message.

Info - This is a quick description of the message (Ex. Position Boundary Management Violation)

Clear Browser Button

This button will erase all messages logged into the browser.

Save Browser ... Button

This button allows the operator to save the contents of the browser to a text file.


DMS Error Statistics Panel

This panel list different summary information about the amount of errors generated for each processor.

Time Text Boxes

These indicate the time of day the last error occurred for that processor, listed in HH:MM:SS.xx.

# Local Msgs Text Boxes

This is the current running total of errors reported by that processor.

More info will be specified later

# Local Msgs Lost Text Boxes

This is the current running total of errors, which although flagged by the processor, where unable to be reported for some reason.

More info will be specified later

# Remote Msgs Text Boxes

This is the current running total of errors reported by that processor.

More info will be specified later

# Remote Msgs Lost Text Boxes

This is the current running total of errors, which although flagged by the processor, where unable to be reported for some reason.

DMS Channel Statistics Panel

All Ranger/Control Station communication travels through the Flight Communications Hub (FCH). This panel is used by the operator to monitor the amount of communications traveling through the hub, looking at each communication channel.

FCH HB Indicator and Text Box

The FCH issues a periodic heartbeat(HB) by sending out an incremented timer. The text box displays the last heartbeat index. The indicator is a short cut which displays green when the heartbeat is being received, red when an update has not occurred for some TBD time.

Reset Statistics Button

This button will zero out the information on this panel except the heartbeat and current time.

Current Time Text Box

The local time is displayed in this box in HH:MM:SS.

RCL Communication Channels Labels

Msg received # Text Box

This is a running total of the number of messages that the FCH has received on the specified channel.

Msg received Last Time Text Box

This was the last time that a message was received by the FCH on the specified channel.

Msg Passed On # Text Box

This is a running total of the number of messages that the FCH has passed on (sent) on the specified channel.

Msg Passed On Last Time Text Box

This was the last time that a message was passed on (sent) by the FCH on the specified channel.

#Rejects CA Text Box

This is a running total of the number of messages that the FCH rejected due to command authority (CA).

#Reject O Text Box

This is a running total of the number of messages that the FCH rejected due to other reasons (O).
