AI Technical Summary

Technical Problem

Existing fire detection systems fail to accurately distinguish between normal and abnormal conditions due to communication errors in wireless transmission, leading to false detection of malfunctions in functioning fire detection devices.

Method used

A detection system with a central control unit that verifies the absence of unique ID information at predetermined intervals, identifies the location of non-responsive devices, and issues alerts only when a certain period of time elapses without reception, using multiple communication methods and redundant device installations to ensure accuracy.

Benefits of technology

Prevents false detection of abnormalities in normal devices by reliably identifying and notifying the location of malfunctioning units, reducing maintenance costs and ensuring timely alerts.

Abstract

This invention provides a detection system that can prevent false detection of an abnormality in a normally functioning detection device. [Solution] The detection system of the present invention is a detection system comprising a plurality of installed detection devices and a central control unit that communicates with the plurality of installed detection devices, wherein each detection device comprises a detection unit that detects the occurrence of an abnormality, a first communication unit that transmits a signal to the central control unit, and a first control unit that controls the first communication unit to transmit unique ID information at predetermined time intervals if the detection unit has not detected the occurrence of an abnormality, and the central control unit determines whether a certain amount of time has elapsed after determining that the unique ID information has not been received at predetermined time intervals, and if the unique ID information has not been received even after a certain amount of time has elapsed, it identifies and notifies the location information of the installation location of the detection device associated with the unique ID information.
