Abstract: An obstacle determination unit determines whether an obstacle exists in a periphery of the work machine. A reporting unit performs reporting showing the obstacle when determination is made that the obstacle exists. An instruction input unit receives an operation instruction for the reporting. An output unit changes a display mode of the obstacle based on the operation instruction.

Abstract: An obstacle determination unit determines whether or not an obstacle is within a detection range being a detection target of the obstacle. A notification unit gives notification indicating the obstacle when determined as the obstacle being present. An operation input unit receives an operation to the display unit for changing the detection range. A change unit changes the size of the detection range based on the operation.

Abstract: A detection system includes an acquisition unit configured to acquire captured data from an imaging device that captures an image of a site, and a dangerous act determination unit configured to determine whether a person who performs a dangerous act is present at the site based on the captured data.

Abstract: An obstacle determination unit determines whether an obstacle is present in a periphery of the work machine. An action detection unit detects an action of an operator of the work machine. An action determination unit determines whether the detected action is a confirmation action executed at the time of safety confirmation. A notification unit changes a mode of notification when the action is determined to be the confirmation action.

Abstract: A work machine periphery monitoring system includes: a camera 30 as a detection unit that detects a person in a periphery of a work machine; an alarm portion that outputs an alarm; a state determination unit 54 that determines a state of a body of the person detected by the camera 30; and an alarm control unit 56 that controls the output of the alarm by the alarm portion on the basis of a determination result of the state determination unit 54.

Abstract: A controller for a work machine includes a main board and a PC board. The main board includes a main controller that runs on a built-in work machine operating system, a first activator that activates the main controller when an activation signal for activating the controller is inputted, and an activation commander that outputs an activation-command signal to the PC board when the main controller becomes active. The PC board includes a PC controller that runs on an operating system for PCs, a network terminal, a network controller that outputs the activation signal to the main board when a specific signal for commanding activation is inputted, and a second activator that activates the PC controller when the activation-command signal outputted from the activation commander of the main board is inputted.

Abstract: A plurality of electronic control devices for carrying out communications by using at least one of a plurality of different types of communication protocols are connected by a multiplex transmission serial communication line which supports communications by a plurality of different frame formats, and one of frame formats is allocated to one type of the communication protocols.

Abstract: A data collection system for a driving machine for collecting data obtained at a plurality of controllers disposed within the driving machine, in which one of the plurality of controllers is used as a master controller to perform sequential polling operation over the other controllers including an external controller through a communication line. The other controller subjected to the polling transmits data obtained at its own controller to the controllers other than its own controller. The master controller continues its polling operation so long as the master controller fails to receive a response to the polling from the external controller. The master controller, when receiving the response to the polling from the external controller, judges that the external controller was connected to a connector for connection with the external controller and stops its polling operation.
