Signalbekräftelse

Signalbekräftelse is a term used to describe the act of confirming receipt and/or understanding of a signal or instruction. It refers to the sender receiving a confirmation from the recipient that the signal has been received, decoded, and acknowledged. The concept is used to improve reliability and safety in communication and control systems, where actions depend on verified transmission.

In telecommunications and data communication, signalbekräftelse is closely related to acknowledgments. An acknowledgment message or signal sent by the receiver confirms successful receipt of data and enables the sender to continue transmission or to retransmit only when errors are detected. This mechanism underpins many automatic repeat request (ARQ) schemes and helps manage flow control and error handling in networks and protocols.

In railway and other safety-critical transport systems, signalbekräftelse often refers to the driver’s or operator’s acknowledgment of a signal, such as a proceed or stop indication. The acknowledgment may be required before a subsequent action is permitted, ensuring that a human operator has observed the signal. If acknowledgment is not received within a specified window, the system can enter a safe state or escalate to an alert or intervention.

Beyond transportation, signalbekräftelse is used in industrial automation and security contexts to confirm that commands, alarms, or messages have been seen and acted upon. This helps maintain traceability, accountability, and overall system integrity.
