Abstract

The fault diagnostic system includes a sensor which is provided in each of a plurality of diagnosis target devices and detects diagnosis target information of the corresponding diagnosis target device, and a diagnosis unit which is provided for one or a plurality of diagnosis target devices and determines whether or not abnormality occurs in the corresponding diagnosis target device based on the diagnosis target information detected by the sensor. The diagnosis unit outputs an abnormality determination result to the outside, and when a specific condition is established, outputs diagnosis target information detected by the sensor after the specific condition is established.

Claims

1. A fault diagnostic system comprising:

a sensor which is provided in each of a plurality of diagnosis target devices and detects diagnosis target information of the corresponding diagnosis target device; and

a diagnosis unit which is provided for one or a plurality of diagnosis target devices and determines whether or not abnormality occurs in the corresponding diagnosis target device based on the diagnosis target information detected by the sensor,

wherein the diagnosis unit outputs a determination result to the outside, and when a specific condition is established, outputs diagnosis target information detected by the sensor after the specific condition is established.

2. The fault diagnostic system according to claim 1, further comprising:

an external device which is connectable to the diagnosis unit,

wherein the external device receives determination results from a plurality of diagnosis units and outputs a transmission request for diagnosis target information to a specific diagnosis unit, and

the diagnosis unit which receives the transmission request for diagnosis target information transmits, to the external device, diagnosis target information detected by the sensor after the transmission request is received.

3. The fault diagnostic system according to claim 2,

wherein the external device does not receive a determination result after the transmission request for diagnosis target information is output.

4. The fault diagnostic system according to claim 2,

wherein the external device receives designation of a specific diagnosis unit which outputs a transmission request for diagnosis target information.

5. The fault diagnostic system according to claim 1, further comprising:

an external device which is connectable to the diagnosis unit,

wherein the diagnosis unit outputs a determination result to the outside in a wireless manner, and on a condition that the external device is connected in a wired manner, transmits subsequent diagnosis target information to the external device.
