The work machine control method includes displaying a display screen including information related to a work machine, on a display device, and switching, when a switching operation unit is operated, the display screen to be displayed on the display device, among a plurality of screens according to a switching pattern. Here, the control method further comprises changing the switching pattern according to a movement state of the work machine.

Work machine control method, work machine control program, work machine control system, and work machine

A display device of a construction machine includes a control unit and a display unit. The display unit displays a display screen having the second display area which is a guidance display area for providing guidance on the operation contents with respect to the display device. The control unit functions as a display control unit that controls the display unit to change a display mode of the second display area according to the operation state of a cutoff lever which is a safety operation member of the construction machine.

Display device and construction machine

A display device includes a display unit; a control unit; an alarm sound output unit; and a reception unit. When the display unit displays a second screen, the control unit assigns, to the reception unit, a function of receiving an output stop instruction that indicates an instruction to stop the output of an alarm sound, and a function of receiving a second instruction that indicates an instruction to transition to a first screen. When the reception unit receives the output stop instruction, the control unit stops the output of the alarm sound. When the reception unit receives the second instruction after having received the output stop instruction, the control unit causes the display unit to display the first screen and causes the alarm sound output unit to output the alarm sound.

Display device and work machine comprising same

The work machine control method includes displaying, on a display device, a display screen including information related to the work machine and executing at least one of a first switching process and a second switching process. The first switching process is a process in which the display screen to be displayed on the display device is switched, in accordance with switching from the enabled state to the disabled state according to an operation state of a disabling operation unit, from a camera screen that includes a captured image of a monitoring area around the work machine to a basic screen that does not include the captured image. The second switching process is a process in which the display screen to be displayed on the display device is switched, in accordance with switching from the disabled state to the enabled state according to the operation state of the disabling operation unit, from the basic screen to the camera screen.

A control method of a work machine in which a rotation number of a fan that takes outside air into an engine room accommodating an engine varies with a rotation number of the engine, includes: executing first control of regenerating a collecting filter unit that collects particulates contained in exhaust gas of the engine by a temperature rise of the exhaust gas; when the work machine is changed from a steady state to a specific state, executing second control of decreasing an amount of working oil discharged from a hydraulic pump by driving of the engine; and, when the first control and the second control are concurrently executed, executing third control of increasing the rotation number of the engine.

Control method of work machine, program, control system, and work machine

This display device includes a display unit, a receiving unit, and a control unit. The display unit displays a first screen having a selection item display area. The receiving unit receives a command for selecting a selection item displayed in the selection item display area. The control unit displays, on the basis of alarm information which indicates that an error has occurred, an alarm mark image in the selection item display area. When the alarm mark image is displayed in the selection item display area, the control unit assigns, to the receiving unit, a function of receiving an alarm mark selection command which is the command for selecting the alarm mark image. When the receiving unit receives the alarm mark selection command, the control unit displays, on the display unit, a second screen for indicating the content of the error.

A method evaluates the mobility of a polymer composition in a high-temperature region of 150&#xb0; C. or above. The method for evaluating a physical property of a polymer composition, the method comprising the steps of: obtaining a thin film sample which is formed on a substrate and which comprises: a fluorescent probe including a fluorescent rare earth complex having a melting point of 200&#xb0; C. or higher; and a target polymer composition; and obtaining a relationship between a temperature and a fluorescent characteristic of the thin film.
