Abstract: A display apparatus that displays log data which indicates when the log data deviates from a normal state and a deviation degree is provided. The display apparatus comprises: a memory to store prediction data including a signal value of a prediction value of the log data and accuracy degree of the prediction value, and a signal value of an actual measurement value of the log data; a control unit to generate a display screen on which a prediction value area indicating an area of the log data in normal state is depicted based on the prediction data and on which a signal wavelength of the signal value of the actual measurement value is depicted based on the signal value of the actual measurement value; and a display unit to display the display screen.

Abstract: Included are a bottom portion having a traveling portion, a body portion having a first pillar portion and a second pillar portion extending in a vertical direction, respectively, from one end and another end in a horizontal direction of the bottom portion, and a top portion including one end connected to an end of the first pillar portion opposite to the bottom portion and including another end connected to an end of the second pillar portion opposite to the bottom portion, an article storage portion that forms an opening with the first pillar portion, the second pillar portion, the top portion, and the bottom portion in such a way that the opening penetrates the body portion, and fixing portions provided in the first and second pillar portions to sandwich the opening and pair up with each other, for fixing an article storage auxiliary instrument.

Abstract: A display apparatus (4) displays log data having at least one of input data to a device (1) or output data from the device (1), the log data being a binary digital signal. The display apparatus comprises: a memory (43) to store prediction data including a signal value of a prediction value of the log data and accuracy degree of the prediction value, and a signal value of an actual measurement value of the log data; a control unit (41) to generate a display screen on which a prediction value area indicating an area of the log data in normal state is depicted based on the prediction data and on which a signal wavelength of the signal value of the actual measurement value is depicted based on the signal value of the actual measurement value; and a display unit (46) to display the display screen. Thereby, the display apparatus (4) is provided, which can display that the log data deviates from the normal state and deviation degree, when the log data is in an anomalous state.
