Abstract

The device diagnosis system according to the present invention is characterized by the following: There are provided devices to which different types of diagnostic software are applied. Diagnostic data on these devices is incorporated into a database server for centralized management. The diagnostic software is executed for device diagnosis according to the diagnostic data of this database server. Consequently, an environment is provided in which the diagnosis of a variety of devices located in different positions in a plant can be controlled and executed systematically.

Claims

1. A device diagnosis system, comprising:

a database server for acquiring and centrally managing diagnostic data on a plurality of devices to which different types of diagnostic software are applied;

a diagnosis execution unit for executing said diagnostic software according to said diagnostic data; and

a human-machine interface for communicating with said database server and said diagnosis execution unit.

2. The device diagnosis system of claim 1, wherein a common interface is provided for the programs of said diagnostic software in said diagnosis execution unit.

3. The device diagnosis system of claim 1 or 2, wherein the work area of said diagnostic software is formed within said database server.

4. The device diagnosis system of claim 1 or 2, wherein said database server acquires diagnostic data from devices under diagnosis through an external tool and by means of direct input by a user.

5. The device diagnosis system of claim 1 or 2, wherein said human-machine interface comprises diagnostic navigators for monitoring said diagnostic software and a diagnostic tool started from any of said diagnostic navigators to provide screens necessary for diagnosis.

6. The device diagnosis system of claim 1 or 2, wherein said diagnostic tool comprises a diagnosis control unit for providing setup screens specific to respective types of said diagnostic software and a common control unit for providing screens common to all types of said diagnostic software.

7. The device diagnosis system of claim 1 or 2, wherein said diagnosis execution unit is connected to an external network.
