摘要
The system (100; 500) comprises sensor means (101, 102, 103, 105a, 105b, 106; 501, 502) suited to detect data representing the presence of a foreign object (505) located in a region (400) to be monitored, situated close to an operating apparatus (307) of an operating machine (300). In addition, the system (100, 500) comprises control means (104; 503) configured to process said data and to provide a control signal when said data correspond to said risk condition concerning the presence of the object (505) in the region (400) to be monitored. The sensor means comprise a distance detector assembly (101, 102; 501, 502) configured to detect data representing the distance of the object (505) and of setting elements placed in the region (400) to be monitored relative to the distance detector (101, 102; 501, 502). The control means (104; 503) are configured to calculate an estimation of the volume occupied by the object (505) and by the setting elements as a function of said data, to compare said estimation and a three-dimensional model concerning the volume occupied by the setting elements, and to assess whether between said estimation and the three-dimensional model there is a variation corresponding to the risk condition according to predetermined criteria. A method is also provided for detecting said risk condition in the region (400) to be monitored.
