Operational state transition and event logging system for an RF transmitter
View Patent ↗The operational state transitions and events of an RF transmitter having a plurality of operational states are monitored and recorded. A plurality of ports are provided that each receive an indication of an occurrence of an event that can cause a transition from one state to another of the plurality of states. A transition status memory stores transition status data representing the status of each associated state. A micro-controller is programmed so that it determines, for each state, from the indications whether a state transition has occurred and, if so, it causes an appropriate change in the associated transition state data stored in the memory.
1. Apparatus for monitoring and recording operational state transitions and events of an RF transmitter having a finite plurality of operational states in a finite state machine, comprising:
a plurality of input ports that each receive an indication of an occurrence of an event that can cause a transition from one state to another of said plurality of states;
a transition status memory that stores transition status data representing the status of each associated state; and
a micro-controller programmed so that it determines, for each state, from said indications whether a state transition has occurred as a result of a said event taking place that causes a said state transition and, if so, it causes an appropriate change in the associated transition state data stored in said memory.
2. Apparatus as set forth in claim 1 wherein a said event may be an external event or an internal event.
3. Apparatus as set forth in claim 1 wherein said indications may represent internal or external events.
4. Apparatus as set forth in claim 1 wherein said stored status data includes data representing the current and previous status of said associated state.
5. Apparatus as set forth in claim 4 wherein a said event may be an external event or an internal event.
6. Apparatus as set forth in claim 4 wherein said indications may represent internal or external events.
7. Apparatus as set forth in claim 4 wherein a said event may be an external event or an internal event and said indications may represent internal or external events.
8. Apparatus as set forth in claim 4 wherein said stored status data further includes an index number unique for each state and the time and date of a said state transition associated therewith.
9. Apparatus as set forth in claim 8 wherein a said event may be an external event or an internal event.
10. Apparatus as set forth in claim 8 wherein said indications may represent internal or external events.
11. Apparatus as set forth in claim 8 wherein a said event may be an external event or an internal event and wherein said indications may represent internal or external events.
12. Apparatus as set forth in claim 1 wherein a said event may be a fault that can cause a said transition.
13. Apparatus as set forth in claim 12 wherein a said event may be an external event or an internal event.
14. Apparatus as set forth in claim 12 wherein said indications may represent internal or external events.
15. Apparatus as set forth in claim 14 wherein said stored status data includes data representing the current and previous status of each said associated state.
16. Apparatus as set forth in claim 15 wherein said stored data further includes an index number unique for each state and the time and data of said state transition associated therewith.
