Abstract

The fault status of various components of an RF transmitter is monitored and recorded. A plurality of ports each receive an indication of an active or an inactive fault status from an associated one of a plurality of monitored the components. A multi-bit fault status structure is provided with each bit being associated with one of the monitored components and having a binary value representative of either an active fault status or an inactive fault status of the associated one of the monitored components. A micro-controller is programmed so that it determines whether any of the fault status indications have been changed from being an inactive status to an active status. If so, for each the monitored component, it sets the corresponding bit in the fault status structure to an active fault indication. If not, it resets the corresponding bit in the fault status structure to an inactive fault indication. The micro-controller is further programmed so that it provides a fault log that contains a record of the faults.

Claims

1. Apparatus for monitoring and recording the fault status of various components of an RF transmitter in real time, comprising:

a plurality of ports that each receive an indication of an active or an inactive fault status from an associated one of a plurality of monitored said components;

a multi-bit fault status structure with each bit being associated with one of said monitored components and having a binary value representative of either a said active fault status or a said inactive fault status of said associated one of said monitored components;

a micro-controller programmed so that it determines whether any of said fault status indications have been changed from being a said inactive status to a said active status and, if so, for each said monitored component it sets the corresponding bit in said fault status structure to an active fault indication and, if not, it resets said corresponding bit in said fault status structure to an inactive fault indication; and

,

wherein said micro-controller is further programmed so that it provides a fault log that contains a record of sequentially occurring faults.

2. Apparatus as set forth in claim 1 wherein said record includes for each fault the fault type and the present status as being active or inactive.

3. Apparatus as set forth in claim 2 wherein said record includes the real time of fault occurrence and the real time that the fault was cleared, if cleared.

4. Apparatus as set forth in claim 1 wherein said record includes for each fault the fault type, present status as being active or inactive, the real time of fault occurrence and the real time that the fault was cleared, if cleared, and it updates said fault log in accordance with the current fault status structure.

5. Apparatus as set forth in claim 1 including a display of said fault log.

6. Apparatus as set forth in claim 5 wherein said display is a video display.

7. Apparatus as set forth in claim 5 wherein said display is a printed display.

8. Apparatus as set forth in claim 7 wherein said record includes for each fault the fault type and the present status as being active or inactive.

9. Apparatus as set forth in claim 5 wherein said record includes for each fault the fault type, present status as being active or inactive, the real time of fault occurrence and the real time that the fault was cleared, if cleared.

10. Apparatus as set forth in claim 1 for additionally monitoring and recording the event status of various monitored events of said RF transmitter comprising:

a plurality of ports that each receive an indication of an active or inactive event status from an associated one of a plurality of monitored events.

11. Apparatus as set forth in claim 10 including a multi-bit event structure with each bit being associated with one of said monitored events and having a binary value representative of either a said active event status or a said inactive event status of said associated one of said monitored events.

12. Apparatus as set forth in claim 11 wherein said micro-controller is further programmed so that it determines whether any of said event status indications have been changed from being an said inactive status to a said active status and, if so, for each said monitored event it sets the corresponding bit in said event status structure to an active event indication and, if not, it resets said corresponding bit in said event status structure to an inactive event indication.

13. Apparatus as set forth in claim 12 wherein said micro-controller is further programmed to provide an event log that contains a record of the monitored events.

14. Apparatus as set forth in claim 10 wherein said record includes for each monitored event, the event type and the present status as being active or inactive.

15. Apparatus as set forth in claim 14 wherein said record includes the real time of event occurrence and the real time that the event was cleared.

16. Apparatus as set forth in claim 10 wherein said record includes for each event the event type, the present status as being active or inactive, the real time of event occurrence and the real time that the event was cleared, if cleared.

17. Apparatus as set forth in claim 10 including a display said event log.

18. Apparatus as set forth in claim 17 wherein said display is a video display.
