SAFETY CRITICAL CONTROL SYSTEM AND METHOD

摘要

This disclosure involves a method of controlling a safety critical control device, the method comprising: sending user inputs to a first state machine, identifying user inputs by the first state machine, determining the correct state to communicate to a second state machine, the correct state being determined by selecting one state of a plurality of states depending on the user inputs, communicating the correct state to a second state machine through a control bus, and determining the correct state for the second state machine based on communication from the control bus.

主权项

1. A safety critical control transmitting and receiving apparatus comprising:
a transmitter that has a first state machine, the first state machine containing a first plurality of identifiable states; a receiver that that has a second state machine, the second state machine containing a second plurality of identifiable states; and a control bus containing a plurality of wires, the control bus electronically coupling the first state machine and the second state machine; wherein, the first state machine transmits a specific state to the second state machine through the control bus.
