To provide a failure sign detection system for a television monitor device capable of pre-maintenance by detecting and reporting a sign of failure of the television monitor device for monitor.SOLUTION: A failure sign detecting system includes: a monitoring camera for photographing a monitoring range; a video display device for displaying a video of the monitoring camera; a video checking camera for photographing a display screen of the video display device; and a data processing device for processing data of the video photographed by the video checking camera to detect a sign of failure of the video display device. In the failure sign detecting system, the data processing device includes: video analysis means for generating a deterioration index of an image of an object to be monitored included in video data by using a numerical model prepared by machine learning in advance; deterioration determination means for determining degree of deterioration of an image by comparing the deterioration index generated by the video analysis means with a preset threshold value; and warning output means for generating an alarm signal for notifying a sign of a failure when the deterioration determination means detects deterioration of a video image of a predetermined value or more and outputting it.SELECTED DRAWING: Figure 1

    【課題】監視用テレビモニタ装置の故障の予兆を検知し報知することで事前保全が可能なテレビモニタ装置の故障予兆検知システムを提供する。【解決手段】監視範囲を撮影する監視用カメラと、監視用カメラの映像を表示する映像表示装置と、映像表示装置の表示画面を撮影する映像チェック用カメラと、映像チェック用カメラが撮影した映像のデータを処理して映像表示装置の故障の予兆を検知するデータ処理装置とを備えた故障予兆検知システムにおいて、データ処理装置は、予め機械学習によって作成された数値化モデルを用いて映像データに含まれる監視対象物の画像の劣化指標を生成する映像解析手段と、映像解析手段により生成された劣化指標と予め設定されたしきい値とを比較して、映像の劣化の程度を判定する劣化判定手段と、劣化判定手段が所定以上の映像の劣化を検知した場合に故障の予兆を知らせる警報信号を生成して出力する警報出力手段を備えるようにした。【選択図】図1
