  • Patent number: 10178302
    Abstract: A safety control device causes an appropriate safety function to operate based on the positional relationship between an operator and a hazard source, the positions of which vary from moment to moment. A hazard source detection section and an operator detection section detect an image of the hazard source and an image of the operator, respectively, from an image of a monitoring area taken by an imaging instrument. A shortest distance search section searches for a shortest distance between the image of the hazard source and the image of the operator. A safety function allocation section selects a safety function based on the shortest distance found by the shortest distance search section. A safety signal generation section transmits a safety signal, which indicates the selected safety function, to an external safety-related instrument using an external communication unit.
