Abstract: A safety control device, a method of controlling safety control device, and a recording medium are provided. A detection zone in which the safety of an operator can be secured and a decrease in an operation rate of a machine can be minimized is set. A safety controller sets a detection zone for executing a safety operation when it is determined that an operator has entered for each operator.

Abstract: Provided is a relay unit that is inexpensive and has a long life, and a method for controlling a relay circuit. A series circuit of mechanical switches is connected in series to a load and a load power supply, and a control unit selects one of the mechanical switches as a selected switch, and performs a switching timing shift, which is constituted by at least one of a first operation in which the selected switch is switched to the closed state after the mechanical switch other than the selected switch, and a second operation in which the selected switch is switched to the open state prior to the mechanical switch other than the selected switch.

Abstract: An optical safety sensor is inexpensively implemented. An optical safety sensor includes: a plurality of light projectors/receivers (a first light projector/receiver and a second light projector/receiver), which includes light projecting portions and light receiving portions; distance measurement portions, which measure distances using the time from light projecting to light receiving; and detection portions, which detect, based on measurement results, an abnormality occurring in any one of the plurality of light projectors/receivers; each of the light receiving portion provided in the plurality of light projectors/receivers receives reflected light caused by the light projected from the light projecting portions of all the plurality of light projectors/receivers.

Abstract: A monitoring system, a monitoring device, and a monitoring method are provided. The monitoring system includes a detection part that detects a position of a worker intruded into a work area, a first specifying part that specifies a worker movable area on the basis of a position of the worker, an image capturing part that captures an image of an area including at least the worker movable area and a predetermined robot occupied area, a second specifying part that specifies a robot movable area from the image of the area, a third specifying part that specifies a human body area of the worker from the image of the area, a measuring part that measures the distance between the robot movable area and the human body area, and a restricting part that restricts movement of the robot when the distance is equal to or less than a predetermined distance.

Abstract: A monitoring system, a monitoring device, and a monitoring method that can facilitate designing of a working environment are provided. Positions of a worker and a robot in a three-dimensional space are specified, at least one protection area to secure safe work of the worker and the robot is set, whether at least one of the worker and the robot intrudes into the protection area is determined, the motion of the robot is limited when at least one of the worker and the robot intrudes into the protection area, a protection area for executing the determination is being switched from multiple set protection areas, and it is possible to set the protection area when the worker works in a common area in which a work area of the worker and a work area of the robot overlap and set the protection area when the robot works in the common area.

Abstract: The reliability of testing a normally closed contact in a relay unit may involve the following. While the load is de-energized, sending a test signal to a normally closed contact (b1, b2) and detecting the state of the returning test signal sent. Resending a test signal when a detection result does not satisfy a predetermined criteria, and re-detecting the state of the returning test signal resent. The state of the returning test signal resent may be assessed as normal when the re-detection result satisfies the predetermined criteria.

Abstract: The reliability of testing a normally closed contact in a relay unit may involve the following. Sending a first test signal to the first normally closed contact and detecting a return state of the first test signal sent, sending a second test signal different from the first test signal to the second normally closed contact and detecting a return state of the second test signal sent; and assessing an abnormality when at least one of the detection result for the return state of the first test signal does not satisfy a first predetermined criteria, and the detection result of the return state of the second test signal does not satisfy a second predetermined criteria different from the first predetermined criteria.
