  • Patent number: 11314243
    Abstract: Provided are a failure prediction support device, a failure prediction support method, and a failure prediction support program, by which a user can easily know an abnormality in time series data relating to an apparatus. The failure prediction support device includes: a difference detection part, acquiring actual machine time series data being time series data relating to control of an apparatus and simulation time series data being time series data relating to control of the simulated apparatus, and detecting a difference between the actual machine time series data and the simulation time series data; a determination part, determining whether or not the difference satisfies a condition predetermined in relation to an abnormality in the actual machine time series data; and a notification processing part, notifying that the difference has been detected when it is determined that the difference satisfies the condition.

  • Patent number: 10935935
    Abstract: A safety control unit includes: a memory; a computation control part; and an input and output unit for connecting the computation control part to a safety input device and an output device to be safely controlled. A system program includes a data refresh program for executing a data refresh of safety control data of the safety input device and the output device and the control data of the memory via the input and output unit. If the computation control part receives a change of a control program, the computation control part stops executing the control program. The computation control part executes the change of the control program while executing a part of the system program including the data refresh. The computation control part resumes executing the control program.

  • Patent number: 10410339
    Abstract: The system behavior is evaluated by checking the position and the orientation of a target processed by a processing device in accordance with a control instruction. A simulator estimates a behavior of a system including a processing device that processes a target. The simulator includes a measurement unit that performs image measurement of an input image including at least a part of a target as a subject of the image, an execution unit that executes a control operation for generating a control instruction directed to the processing device based on a measurement result obtained by the measurement unit, and a reproduction unit that reproduces, in the system, a behavior of a target detected in the input image together with information about a type and an orientation of the target based on time-series data for the control instruction output from the execution unit and the measurement result from the measurement unit.

  • Patent number: 10401844
    Abstract: A structure allows more efficient simulation using preliminary obtained image data for a target such as a workpiece. A simulator includes a creating unit that virtually creates a simulation target system in a three-dimensional virtual space, a measurement unit that performs image measurement of preliminary obtained image data using a visual sensor and outputs a measurement result, a reception unit that receives a setting of an imaging area defined for the visual sensor in a manner associated with the created system, a calculation unit that calculates a transform parameter based on a relative positional relationship between the created system and the set imaging area, and an execution unit that receives an input of a result obtained by transforming the measurement result generated by the measurement unit using the transform parameter, and executes a control operation in accordance with a control program associated with the system.
