    摘要： A system for the safe control of safety protections comprises at least one first control device (2) placed outside the safety perimeter (P) for sending commands to stop and enable the machine or plant (M) following the opening/closing of the accesses (A1, A2), a first safety switch (3) placed close to one or more of the accesses (A1, A2) for their locking and/or unlocking, one or more actuators having a transponder with identification code for interacting with the first control device and/or safety switch, at least one control unit operatively connected to the first control device and to the safety switch to receive the actuation commands and enable the operation of the machine or plant (M) between an operating condition of fully operation and a safety operating condition. Second means are also provided for enabling the exit from the safety perimeter (P) for one or more operators.

    摘要： Identifying critical zones of machines is provided. A digital twin simulation of a machine is performed. An analysis of a set of historical incident records corresponding to the machine is performed to determine areas surrounding the machine that will be impacted by propagation of different types of incidents corresponding to the machine. A task performed by the machine, an operating context of the machine, an aggregate energy of the machine, and an area in the industrial machine environment affected by propagation of released energy from the machine are identified based on the digital twin simulation and the analysis of the set of historical incident records. A set of critical zones corresponding to the machine is identified based on the task performed by the machine, the operating context of the machine, the aggregate energy of the machine, and the area in the industrial machine environment affected by propagation of released energy.

    摘要： On the basis of a numerical control program for controlling the motion of a machine tool 2, a motion-path generation device 55 generates a motion path concerning control axes of a robot 3 provided in proximity to the machine tool 2. The motion-path generation device 55 comprises: a model update unit 57 that acquires start coordinate values on the control axes and current tool coordinate values of the machine tool 2 and updates a robot system model on the basis of these coordinate values, the robot system model being configured by disposing three-dimensional models of the robot 3, the machine tool 2, and objects in the vicinity of the machine tool 2 in a virtual space; an interference-avoiding-path generation unit 56 that generates a target motion path starting from the start coordinate values and arriving at end coordinate values on the control axes, the end coordinate values being specified on the basis of the numerical control program, while avoiding interference in the robot system model; and a data transmission/reception unit 59 that transmits an instruction including the target motion path to a robot control device 6.

    摘要： Systems, methods, and apparatus for a detector and reflector for automation cell safety and identification are disclosed. In one or more embodiments, a method for machinery safety comprises transmitting, by an active transponder, at least one interrogation signal. The method further comprises receiving, by at least one passive transponder located on a user or on an item, the interrogation signal(s). Also, the method comprises generating, by a non-linear device of the passive transponder(s) in response to the interrogation signal(s), at least one response signal. In addition, the method comprises receiving, by the active transponder, the response signal(s). Additionally, the method comprises determining, by at least one processor, a location of the passive transponder(s) based on the response signal(s). Further, the method comprises determining, by the processor(s), whether the passive transponder(s) is located within a threshold distance away from machinery by using the location of the passive transponder(s).
