Publication number: 20230003004Abstract: According to the present invention, a controller determines whether the current performance of a piece of equipment satisfies a determination criterion, on the basis of the current state of the equipment, acquired by a sensor. If the controller determines that the current performance of the equipment does not satisfy the determination criterion, the controller calculates a parameter with which the performance of the equipment satisfies the determination criterion, on the basis of the current state of the equipment, acquired by the sensor, and the determination criterion. The controller changes a parameter managed by a storage device to the parameter calculated by the controller.Type: ApplicationFiled: December 10, 2020Publication date: January 5, 2023Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Ryo HAMAMOTO, Kazuomi ENDO

Publication number: 20220398347Abstract: An operation unit-side key and a body unit-side key are set for each apparatus, and set to be different for each apparatus. An operation unit-side code generation unit generates an operation unit-side tampering detection code based on specific information that is information for a specific apparatus and the operation unit-side key that corresponds to the specific apparatus. A body unit-side code generation unit generates a body unit-side tampering detection code based on the specific information received from an operation unit and the body unit-side key that corresponds to the specific apparatus. A tampering detection unit detects tampering with the specific information by determining whether the operation unit-side tampering detection code matches the body unit-side tampering detection code.Type: ApplicationFiled: November 4, 2020Publication date: December 15, 2022Applicant: KOBELCO CONSTRUCTION MACHINERY CO., LTD.Inventors: Ryo HAMAMOTO, Kazuomi ENDO

Patent number: 11449473Abstract: A data tracking unit 80 includes a distribution history storage unit 81 that stores a distribution history of data, a tracking tag adding unit 82 that adds a tracking tag used to identify tracking data, a first transmission unit 83 that transmits data to which the tracking tag is added to the component 90, and a distribution history registration unit 84 that registers a distribution history of the data to which the tracking tag is added, in the distribution history storage unit 81. The component 90 includes a second transmission unit 91 that transmits data to which the same tracking tag as a tracking tag added to the received data is added to another component 90 or the data tracking unit 80. The history registration unit 84 registers a result of tracking of data associated with the same tracking tag, as a distribution history of the data, in the distribution history storage unit 81.Type: GrantFiled: May 26, 2017Date of Patent: September 20, 2022Assignee: NEC CORPORATIONInventors: Takayuki Sasaki, Ryo Hamamoto
