Abstract

A failure diagnosis system includes: a sensor; an abnormality determination unit that determines whether an abnormality occurs in a diagnosis target device corresponding to the sensor on the basis of diagnosis target information detected by the sensor; a screen display controller that identifiably notifies a diagnosis target device for which it is determined by the abnormality determination unit that the abnormality occurs; a layout setting unit that sets a facility layout of a facility; and a disposition setting unit that sets a disposition of each diagnosis target device in the facility layout. The screen display controller identifiably notifies a diagnosis target device associated with a sensor that detects diagnosis target information that is a basis of the determination that the abnormality occurs, in a disposition screen display region 521 in which diagnosis information acquisition units are disposed on the facility layout.

Claims

1. A failure diagnosis system comprising:

a first sensor that ascertains, from a first diagnosis target device in a facility, first diagnosis target information;

a second sensor that ascertains, from a second diagnosis target device in the facility, second diagnosis target information;

a terminal device that causes a display unit to display, on a screen, an image of the first diagnosis target device, an image of the second diagnosis target device, and a layout of the facility; and

a processing unit that executes a diagnosis process on the first diagnosis target information to determine an occurrence of an abnormality in the first diagnosis target device, and executes the diagnosis process on the second diagnosis target information to determine an occurrence of an abnormality in the second diagnosis target device,

wherein when the diagnosis process determines the occurrence of the abnormality in the first diagnosis target device, the terminal device causes the display unit to display a first indicator on the screen,

wherein when the diagnosis process determines the occurrence of the abnormality in the second diagnosis target device, the terminal device causes the display unit to display a second indicator on the screen,

wherein the terminal device causes the display unit to display a setting screen to create a facility layout and set disposition of the first diagnosis target device and the second diagnosis target device in the facility layout,

wherein the terminal device causes the display unit to display, on the setting screen, a part region, in which a part image of the facility is displayed, and a facility layout display region, and create the facility layout by receiving an operation of disposing, in the facility layout display region, the part image displayed in the part region,

wherein the terminal device receives an operation of disposing images of the first diagnosis target device and the second diagnosis target device in the created facility layout on the setting screen,

wherein the image of the first diagnosis target device depicts, on the screen, a location in the layout where the first diagnosis target device is sited, and

wherein the image of the second diagnosis target device depicts, on the screen, a location in the layout where the second diagnosis target device is sited.

2. The failure diagnosis system according to claim 1, wherein the terminal device causes the display unit to display, on the screen, a sensor image of the first sensor.

3. The failure diagnosis system according to claim 2, wherein the sensor image of the first sensor depicts, on the screen, a location in the layout where the first sensor is sited.

4. The failure diagnosis system according to claim 2, wherein the terminal device causes the display unit to display, on the screen, detailed information pertaining to the first diagnosis target information when a cursor on the screen selects the sensor image of the first sensor.

5. The failure diagnosis system according to claim 2, wherein the first indicator is a color change of the sensor image of the first sensor.

6. The failure diagnosis system according to claim 1, wherein the first indicator is a color change of the image of the first diagnosis target device.

7. The failure diagnosis system according to claim 1, wherein the terminal device causes the display unit to display, on the screen, detailed information pertaining to the first diagnosis target information when a cursor on the screen selects the image of the first diagnosis target device.

8. The failure diagnosis system according to claim 1, wherein the second indicator is a color change of the image of the second diagnosis target device.

9. The failure diagnosis system according to claim 8, wherein the terminal device causes the display unit to display, on the screen, the sensor image of the second sensor in the layout.

10. The failure diagnosis system according to claim 8, wherein the sensor image of the second sensor depicts, on the screen, a location in the layout where the second sensor is sited.

11. The failure diagnosis system according to claim 1, further comprising:

a layout acquisition unit that acquires a facility layout drawing and sets the facility layout drawing as the layout.

12. The failure diagnosis system according to claim 1,

wherein the processing unit executes different processes on the first diagnosis target information and the second diagnosis target information in accordance with a difference between an interconnect distance between the processing unit and the first sensor and an interconnect distance between the processing unit and the second sensor.

13. The failure diagnosis system according to claim 12,

wherein the processing unit executes different filtering processes on the first diagnosis target information and the second diagnosis target information.

14. The failure diagnosis system according to claim 12,

wherein the processing unit executes different correction processes on the first diagnosis target information and the second diagnosis target information.

15. The failure diagnosis system according to claim 1,

wherein, when the occurrence of the abnormality in the first diagnosis target device is determined, the terminal device causes the display unit to display that an abnormality of the processing unit to which the first sensor is connected also occurs.
