| description | To provide a monitoring device, a monitoring system, and a monitoring method for estimating a flow rate of flare gas discharged from a flare stack.SOLUTION: A monitoring device 30 in a monitoring system in which a camera and a video acquisition device, the video acquisition device and a video distribution device, the video distribution device and a monitoring monitor, and the video distribution device and the monitoring device are communicably connected to each other comprises a video acquisition unit 31 for acquiring video acquired by capturing flares, a video analysis unit 33 for analyzing the video and identifying pixels in which the flares are captured, a flare volume estimation unit 34 for estimating a volume of flares based on the pixels in which the flares are captured, a flare gas flow rate estimation unit 35 for estimating a flow rate in a predetermined unit time of flare gas that generates the flares based on the volume of flares calculated for continuously captured video, and an output unit 37 for comparing the flow rate of flare gas and a predetermined threshold value to generate an alarm.SELECTED DRAWING: Figure 2
【課題】フレアスタックから放出されるフレアガスの流量を推定する監視装置、監視システム及び監視方法を提供する。【解決手段】カメラと映像取得装置、映像取得装置と映像分配装置、映像分配装置と監視用モニター、映像分配装置と監視装置が、夫々通信可能に接続されている監視システムにおいて、監視装置３０は、フレアを撮影した映像を取得する映像取得部３１と、映像を解析し、フレアが写った画素を識別する映像解析部３３と、フレアが写った画素に基づいて、フレアの体積を推定するフレア体積推定部３４と、連続して撮影された映像について算出された前記フレアの体積に基づいて、フレアを発生させるフレアガスの所定の単位時間における流量を推定するフレアガス流量推定部３５と、フレアガスの流量と所定の閾値とを比較してアラームを発報する出力部３７と、を備える。【選択図】図２ |
