Fire Pump Control Logic That Blocks Stop Signals During a Fire

The patent replaces computer program execution with pure electronic hardware logic (logic circuits, state machines, or hardwired control logic). This substitution eliminates software-related complexities and errors while maintaining automated control capability through electronic decision-making circuits that directly respond to sensor inputs and control pump operations.

The patent employs simpler, more reliable electronic control components that can be easily replaced if needed, rather than complex programmable systems. The control logic is implemented in fixed hardware that is inherently more reliable for critical fire safety functions where software bugs could be catastrophic.

The system performs preliminary verification by requiring multiple independent detection signals or a specific pattern of signals before suppressing the stop command and activating the fire response. This preliminary check ensures that the detected condition truly represents a fire event rather than a transient anomaly, thereby preventing false activations while maintaining rapid response capability.

The control unit continuously monitors detection signals and provides feedback to verify the persistence and consistency of fire indicators before triggering the fire response. The system adjusts its response based on the feedback from multiple sensors and the temporal pattern of signals, ensuring reliable discrimination between actual fires and false alarm conditions.
