Abstract

A protocol chip transmits the request from the host apparatus to a first processor through a first address translation unit. A first processor transmits a response to the request from the host apparatus, to the protocol chip through the first address translation unit. When the first processor stops processing, an instruction to transmit the request from the host apparatus to a second processor is transmitted to the protocol chip. When receiving the instruction to transmit the request from the host apparatus to the second processor, the protocol chip transmits the request from the host apparatus to the second processor through a second address translation unit. The second processor transmits the response to the request from the host apparatus to the protocol chip through the second address translation unit.

Abstract

The present disclosure provides an electronic control device capable of suppressing variations in the position of a work machine calculated based on satellite signals received by a GNSS terminal due to changes in the GNSS communication environment, and eliminating the position error after improvement of the communication environment in a shorter time than before. The electronic control device includes: a positioning quality determination section 211 that determines whether the positioning quality is good or poor based on GNSS information; a traveling state determination section 212 that determines the traveling state, including a stop state, based on the velocity of the work machine; and a smoothing section 213 that performs smoothing processing to the GNSS information. The smoothing section 213 changes the processing intensity to weak if the smoothing condition is not satisfied, the condition being that the positioning quality is good and the traveling state is stop, and changes the processing intensity to strong after a time equivalent to update cycle since the smoothing condition has been satisfied.

Abstract

A storage device receives an access request specifying one of one or more LDEVs (one or more logical volumes provided to one or more hosts) from one host. In response to the access request, the storage device accesses a page allocated to an access destination area of the LDEV among a plurality of pages (plurality of logical storage areas that can be allocated to one or more LDEVs). The storage device or a storage device management system identifies, based on management information including information representing a write status characteristic for each of the plurality of pages, a mark target page as a low-write frequency page where a certain number or more of writes have occurred during a certain period of time and checks the presence or absence of a ransomware attack possibility that the number of the mark target pages is equal to or greater than a threshold.

Abstract

This processing authority transfer system comprises a first terminal and a processing execution subject. The first terminal holds a first certificate that is based on biological information of a mandator of processing, and that indicates an execution condition and execution content for the processing and an identifier of a transferee of the authority for executing the processing. The execution subject transmits, to the first terminal, an identifier of said execution subject and information indicating whether the execution condition has been satisfied. When determining that, on the basis of said information having been received from the execution subject in a first certificate verification, there is an execution subject which has transmitted information indicating that the execution condition has been satisfied, the first terminal determines whether the identifier of said execution subject coincides with the identifier indicated by the first certificate, and performs transfer of the authority of the processing indicated by the execution content to the execution subject on the basis of a result of the first certificate verification.

Abstract

In the present invention, a control device for a work machine sets a release start position and a release stop position lined up in a direction having a component of the longitudinal direction of a vessel, on the basis of information regarding the position of the vessel acquired by a vessel position acquisition device at a position where an excavation action is completed, the release start position being a position where an excavated-material-releasing operation carried out above the vessel is started, and the release stop position being a position where the releasing operation is stopped. On the basis of the orientations of a work device and a turning body detected by an orientation detection device, the control device controls the operations of the work device and/or the turning body, thereby causing a control point of the work device to move from the release start position to the release stop position and controls the operation of the work device so that the bucket ground angle reaches a preset release stop angle until the control point of the work device moves from the release start position to the release stop position.

Abstract

The purpose of the present invention is to provide a construction machine that is capable of allowing an operator to correctly recognize the cause of an alarm and prompting the operator to take an appropriate avoidance action in accordance with the likelihood of the machine body and an obstacle coming into contact with each other. For this purpose, in the case in which an obstacle detection device detects an obstacle in the area surrounding the machine body, a controller causes an alarm output device to output an alarm sound in which a warning by means of audio for notifying about the approach of the obstacle and a warning by means of a buzzer sound having an intensity set in accordance with the distance between the machine body and the obstacle are combined.

Abstract

Provided are a work machine management device and management system that are capable of enhancing the accuracy in determining whether there is an abnormality in an oil. In the present invention, a management server manages an oil used by a drive device for a hydraulic shovel. The management server has: an oil replacement sensing unit that acquires a measurement value, for the properties of an oil of interest, from an oil sensor mounted on the hydraulic shovel, and senses the replacement of the oil of interest on the basis of a change in the properties of the oil of interest; an oil-type-candidate selection unit that, on the basis of the properties measured by the oil sensor after replacement of the oil of interest has been sensed, selects a plurality of oil type candidates for the replaced oil of interest; an oil type acquisition unit that outputs an instruction that the type of the oil of interest can be selected from the plurality of oil type candidates, and receives a selection input for the type of the oil of interest so as to obtain the type of the oil of interest; and an oil abnormality determination unit that determines whether there is an abnormality in the oil of interest by comparing the properties measured by the oil sensor and a threshold corresponding to the type of the oil of interest.

Abstract

This construction machine comprises a machine body, a position-measuring device that measures a position in a predetermined coordinate system in accordance with a positioning signal from a positioning satellite received by a satellite positioning antenna, and an antenna support member that is disposed on the machine body in order to support the satellite positioning antenna. In this construction machine, at least one device, from among a shape-measuring device that measures the shape of objects around the machine body, an imaging device that acquires images of the surroundings of the machine body, and an information notification device that issues a notification regarding the surroundings of the machine body, is attached to the antenna support member. This makes it possible to minimize any increase in the proportion of a space for sensor installation occupying the space on the construction machine, and to improve the maintainability of the installed sensor.
