Embodiment Construction
[0068] according to Figure 1 ~ Figure 3 , the inspection method using the mobile terminal according to the first embodiment of the present invention will be described. This inspection method is a method for inspecting the abnormality of the rotating machine part 1, and uses a general-purpose portable information terminal 2 such as a smart phone, a dedicated sensor 3 connected thereto, and is connected to the portable information terminal 2 via a communication network 7 such as the Internet. server6. The server 6 is provided with a database 15 that stores data processing software 4 and data (related to specification data) 5 such as specifications of the rotary machine component 1 . The server 6 may be a dedicated server for the inspection method of the rotating machine part using a portable terminal, or may be a server having various application programs and data unrelated to the inspection method of the rotating machine part using a mobile terminal. The type of function.

Provided is an inspection method that allows the operating state of bearings and other rotary machine components to be easily inspected by using a portable information terminal such as a smartphone and a dedicated sensor. Further provided is an inspection method that is able to reduce the likelihood of detection data being damaged from communication failures in communication from the portable information terminal to the server and allows processes such as diagnostics to be performed at a level equivalent to an inspection of the full circumference of the rotary machine component. The method employs a general-purpose portable information terminal (2) such as a smartphone and a dedicated sensor (3) to be connected thereto. Detection data detected by the dedicated sensor (3) is transmitted from the portable information terminal (2) to a server (6), and the server (6) processes the data and transmits the processing results to the portable information terminal (2). The portable information terminal (2) displays the sent processing results on a screen (21a). The length of time for one detection with the dedicated sensor (3) is set to be less than the time of one rotation of the rotary machine component (1), and the worker would assess whether there are any anomalies in the rotary machine component (1) on the basis of results of multiple detections and data processing.
Description
[0001] related application [0002] The present invention claims that the application date is December 12, 2013, the application number is JP Japanese Patent Application No. 2013-256659, and the application number is JP Japanese Patent Application No. 2013-256889. cited as part of the application. technical field [0003] The present invention relates to an inspection system and inspection method using a portable terminal for rotating machine parts, in which the operation status of rotating machine parts having rolling elements such as rolling bearings and constant velocity ball joints is determined by using a widely used smartphone or the like. The portable information terminal to check. Background technique [0004] As inspection methods for rotating machine parts such as bearings, there are methods of measuring vibration and temperature of rotating machine parts such as bearings, displaying the state, and inspecting methods (for example, Patent Documents 1 and 2). [00...
