Abstract
A warning system according to an embodiment includes an acquisition unit, an analysis unit, and a calculation unit. The acquisition unit acquires, from first sensor data including information on a target, condition information on the target. The analysis unit analyzes, from second sensor data including information on a region, current state information on an object included in the region and action prediction information on the object. The calculation unit calculates a degree of caution, based on the condition information on the target, the current state information on the object, and the action prediction information on the object.
Claims17
A warning system comprising:
- a hardware processor configured to function as:
- an acquisition unit configured to acquire, from first sensor data including information on a target that is a machine in a factory or at a construction site, condition information on an operation of a motion of the target;
- an analysis unit configured to analyze, from second sensor data including information on a region, current state information on an object that differs from the target and that is included in the region and action prediction information on the object;
- and
- a calculation unit configured to calculate a degree of caution, based on the condition information on the target, the current state information on the object, and the action prediction information on the object, wherein,
- the region is a place where work requires a predetermined number of persons including a specific person, and
- the calculation unit calculates
- a first degree of caution when a number of persons in the region is less than the predetermine number of persons,
- a second degree of caution when no specific person is present in the region, and
- a third degree of caution when the predetermined number of persons including the specific person are present in the region and an improper person is present in the region.
A warning method implemented by a computer, the method comprising:
- acquiring, by a warning system, from first sensor data including information on a target that is a machine in a factory or at a construction site, condition information on an operation of a motion of the target;
- analyzing, by the warning system, from second sensor data including information on a region, current state information on an object that differs from the target and that is included in the region and action prediction information on the object;
- and
- calculating a degree of caution by the warning system, based on the condition information on the target, the current state information on the object, and the action prediction information on the object, wherein,
- the region is a place where work requires a predetermined number of persons including a specific person, and
- calculating the degree of caution includes calculating
- a first degree of caution when a number of persons in the region is less than the predetermine number of persons,
- a second degree of caution when no specific person is present in the region, and
- a third degree of caution when the predetermined number of persons including the specific person are present in the region and an improper person is present in the region.
A computer program product having a non-transitory computer readable medium including programmed instructions, wherein the instructions, when executed by a computer, cause the computer to function as:
- an acquisition unit configured to acquire, from first sensor data including information on a target that is a machine in a factory or at a construction site, condition information an operation of a motion of on the target;
- an analysis unit configured to analyze, from second sensor data including information on a region, current state information on an object that differs from the target and that is included in the region and action prediction information on the object;
- and
- a calculation unit configured to calculate a degree of caution, based on the condition information on the target, the current state information on the object, and the action prediction information on the object, wherein,
- the region is a place where work requires a predetermined number of persons including a specific person, and
- calculating the degree of caution includes calculating
- a first degree of caution when a number of persons in the region is less than the predetermine number of persons,
- a second degree of caution when no specific person is present in the region, and
- a third degree of caution when the predetermined number of persons including the specific person are present in the region and an improper person is present in the region.
