Patent number: 11314243Abstract: 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.Type: GrantFiled: January 18, 2019Date of Patent: April 26, 2022Assignee: OMRON CorporationInventors: Keizo Tanaka, Haruna Shimakawa, Katsushige Ohnuki

Patent number: 10935935Abstract: 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.Type: GrantFiled: August 23, 2017Date of Patent: March 2, 2021Assignee: OMRON CORPORATIONInventors: Tatsuya Kojima, Koji Yaoita, Takamasa Ueda, Katsushige Ohnuki

Patent number: 10410339Abstract: 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.Type: GrantFiled: December 1, 2016Date of Patent: September 10, 2019Assignee: OMRON CorporationInventors: Katsushige Ohnuki, Yasunori Sakaguchi, Haruna Shimakawa

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.Type: ApplicationFiled: August 23, 2017Publication date: July 11, 2019Applicant: OMRON CorporationInventors: Tatsuya KOJIMA, Koji YAOITA, Takamasa UEDA, Katsushige OHNUKI
