To detect a failure of a load detection device when a car is stopped.SOLUTION: A load detection device for an elevator according to the present embodiment includes a load sensor, an image analysis unit, and a failure detection unit. The load sensor detects a load in the elevator car. The image analysis unit analyzes the image in the car based on the image of a camera that photographs the inside of the car. The failure detection unit detects a failure of the load sensor based on the load detected by the load sensor and the image in the car analyzed by the image analysis unit.SELECTED DRAWING: Figure 5
【課題】かごが停止しているときに荷重検出装置の故障を検出する。【解決手段】本実施形態に係るエレベータの荷重検出装置は、荷重センサと画像解析部と故障検出部とを備える。荷重センサは、エレベータのかご内の荷重を検出する。画像解析部は、かご内を撮影するカメラの画像に基づいて、かご内の画像を解析する。故障検出部は、荷重センサが検出した荷重と画像解析部が解析したかご内の画像に基づいて、荷重センサの故障を検出する。【選択図】図5
