AI Technical Summary
In modern urban high-rise buildings and dense communities, the fire sensors of smart fire protection systems suffer from increased radio background noise, which reduces the distinguishability between communication signals and noise, increases the frequency of data packet retransmission, and raises transmission delays. This makes it impossible to receive initial fire data in a timely and complete manner, thus missing the early warning window and resulting in low accuracy and reliability of early warnings.
By acquiring fire sensor data, conducting data quality assessment, adjusting the data reception time window based on the data quality score, receiving sensor data to be assessed, conducting fire risk assessment, and generating fire emergency early warning information.
It enables accurate identification of sensors with degraded communication quality in complex radio environments, ensuring timely and complete delivery of weak fire signals, and improving the accuracy and reliability of fire early warning.
