Abstract

An object of the invention is to provide an anomaly diagnosis apparatus of a machine installation for eliminating the need for the user to have a dedicated analytical instrument or a skill required for anomaly diagnosis of a sliding member and enabling the user to easily make an anomaly diagnosis request with a small burden and get the diagnosis result promptly.

In the invention, an anomaly diagnosis apparatus for analyzing sound or vibration data produced by a machine installation and diagnosing the presence or absence of an anomaly in a sliding member in the machine installation is made up of a diagnosis processing server (1) and a user information processing terminal (3) which are connected through a network (2). The diagnosis processing server (1) receives the sound or vibration data produced by the machine installation and information for identifying the sliding member used with the machine installation through the network (2) from the user information processing terminal 3, makes an anomaly diagnosis of the machine installation based on the received data, and transmits the diagnosis result through the network (2) to the user information processing terminal (3), thereby lightening the burden of the user and executing anomaly diagnosis processing promptly.

Claims

1. (canceled)

2. An anomaly diagnosis apparatus of a machine installation wherein an actual measurement data analysis program for analyzing actual measurement vibration data recording sound or vibration produced when a sliding member used with the machine installation operates, determination criterion data recording information used as a determination criterion of the presence or absence of an anomaly in the sliding member used with the machine installation, and a determination program for comparing the analysis result of the actual measurement data analysis program with the determination criterion data and diagnosing the presence or absence of an anomaly in the sliding member are previously uploaded to a diagnosis processing server connected to a network in an executable data format in an information processing terminal of a user using the machine installation so as to enable the programs and the data to be downloaded into the user information processing terminal, characterized in that

the user of the machine installation downloads the actual measurement data analysis program, the determination program, and the determination criterion data through the network into the user'"'"'s information processing terminal, inputs the actual measurement vibration data through an interface to the user'"'"'s information processing terminal whenever necessary, and executes the actual measurement data analysis program and the determination program in the user'"'"'s information processing terminal for diagnosing the presence or absence of an anomaly in the sliding member used with the machine installation in the user'"'"'s information processing terminal.

3. The anomaly diagnosis apparatus of the machine installation as claimed in claim 2 wherein the Internet is used as the network.

4. The anomaly diagnosis apparatus of the machine installation as claimed in claim 2 wherein an authentication program for comparing with customer information data of information required for authenticating the user using the machine installation and allowing the user to download the actual measurement data analysis program, the determination program, and the determination criterion data when authenticating the user accessing the diagnosis processing server as the authorized user is built in the diagnosis processing server.

5. The anomaly diagnosis apparatus of the machine installation as claimed in any of claim 2 wherein a protect program for limiting the number of use times or the expiration date in the downloading information processing terminal is added to the programs and the data downloaded from the diagnosis processing server into the user information processing terminal.

6-25. -25. (canceled)
