An abnormality symptom analyzing device comprises: a data request receiver to perform request and reception of data, required for analyzing an abnormality symptom(s), including measurement information obtained from a sensor(s) of a facility, an abnormality symptom(s) detected from the measurement information and inspection information of the facility; a data storage device to store the data acquired by the data request receiver; a coordination circuitry to perform the registration of data to display a screen display component(s) on a display device and the correspondence of data coordinated between screen display components to a screen display component(s) coordinated, and to store information modified according to input contents from an input device, whereby modification contents are coordinated to the screen display components; and a component graphics-drawing management circuitry to acquire data through the coordination circuitry, and to display details information of the facility and propagation information of an abnormality symptom(s) in signals.

Abnormality symptom analyzing device

An operation status reproducing device includes an onboard information obtaining unit that obtains onboard information corresponding to date and time from an onboard device mounted on a designated train being a train specified by a train number and the date and time externally designated, a specific event detecting unit that specifies time at which a specific event occurs by analyzing the onboard information, a ground information obtaining unit that obtains ground information in a certain period including the time at which the specific event occurs from a ground device, an external information obtaining unit that obtains external information including weather information in a certain period including the time at which the specific event occurs, and a reproduction image generating unit that generates a reproduction image illustrating a past operation status of the designated train based on the onboard information, the ground information, and the external information.

Operation status reproducing device, display device, and operation status reproducing method

A display device includes a drawing processing unit displaying a status of a device mounted on a train car, and a data collection unit including a signal definition holding unit holding signal definitions to be bases of first signals requesting information on the status of the device, a signal mapping management unit acquiring configuration information on the number of cars and a traveling direction, and generating the first signals, based on the signal definitions and configuration information to request information on the device status, a signal data storage unit holding a value of a second signal as information on the device status acquired by the signal mapping management unit's request, and a signal mapping generation unit generating signal mapping information for specifying the order of the cars on a display screen, based on the configuration information, and outputting the signal mapping information to the signal data storage unit.

Display device and on-board information display method

A drawing component generation device generating a drawing component when a train cab display device installed in a train is to display status of a device installed in a car of a train on a display screen using the drawing component, which is a modularized part of display content to be displayed on the display screen, includes a reception unit providing an input screen displaying entries for information used for generating the drawing component based on a train display definition defining a train formation pattern, and a device layout definition defining a layout pattern, and receiving input of information for the entries from a user; and a generation unit generating the drawing component based on the train display definition, the device layout definition, input information being information input from the user on the reception unit, and a display pattern definition defining display content relating to the status of the device.

Drawing component generation device, display system, and drawing component generation method

A technique capable of estimating an error point in a logic diagram appropriately. A logic diagram display device includes: a signal line correctness/incorrectness determining unit that determines for each test whether each signal line in the logic diagram is correct or incorrect based on a signal line status value of each signal line and a test table; and a signal line correctness/incorrectness result summarizing unit that calculates a correctness/incorrectness result summarized value of each signal line based on a result of determination about the correctness or incorrectness of each signal line. The logic diagram display device further includes: an error signal line estimating unit that estimates an error in each signal line based on the correctness/incorrectness result summarized value of each signal line; and a display that displays each signal line in the logic diagram in a display style responsive to the error in each signal line.

Device for and method of estimating error point in logic diagram

A logic diagram processing device has a logic diagram relocating unit which relocates operation elements while maintaining control logics equivalently so that the operation elements as compared overlap in the case where a plurality of designated logic diagrams are overlapped, and a logic diagram overlapping unit which overlaps the plurality of designated logic diagrams in which the operation elements are relocated by the logic diagram relocating unit. The logic diagram processing device also includes a display unit which displays the plurality of designated logic diagrams overlapped by the logic diagram overlapping unit in a predetermined display method by which a common part or the difference of the operation elements can be discriminated, and a display control unit which switches the predetermined display method to display in the display unit in accordance with an instruction from the outside.
