Problems solved by technology

Therefore, there is a problem that an abnormality of a moving body cannot be detected.
However, on the contrary, if all abnormalities detected when there is an abnormality in the equipment on the ground are also judged as abnormalities of the mobile body, there is a problem of judging that there is an abnormality in the mobile body without abnormalities.

Embodiment Construction

[0027] Hereinafter, refer to the first embodiment of the present invention Figure 1 to Figure 5 Be explained.

[0028] figure 1 It is a configuration diagram showing a configuration example of the train 101 of the present embodiment. The train 101 of this example is configured by connecting a plurality of vehicles 102a to 102c with a connector 109, and can move on a track.

[0029] On each of the vehicles 102a to 102c, at least one measuring device 103a to 103c for measuring various states of the vehicle is mounted on one or more vehicles. In this example, one measuring device 103a-103c is mounted on each of the vehicles 102a-102c. The measurement devices 103a to 103c in this example are described assuming that the vibration of the moving body is input as the measurement data of the moving body, but for example, sound waves or the like may be input as the measurement data. For example, an acceleration sensor is provided when measuring vibration, and a microphone is provid...

Abstract

A vehicle moves on the ground, and is mounted with a measuring device for measuring a vehicle state and a speedometer for measuring a vehicle speed. An abnormality detecting device 104 gathers respective measuring data and speed data, and has a data separating means 207 for separating data into a steady component detected regardless of a position, a ground component detected in common to a plurality of measuring data in a specific position, and a moving body component detected only by a specific measuring device. The device provides an abnormality-detecting system capable of separately detecting abnormal vibration by the deterioration in a device and light failure from abnormality of a ground facility.

Description

technical field [0001] The present invention relates to an abnormality detection system applicable to mobile bodies such as railway vehicles, and more particularly to an abnormality detection technology for detecting abnormalities of a measuring device having vibrations etc. on a mobile body. Background technique [0002] Conventionally, measurement devices installed on mobile bodies such as railway vehicles running on the ground have been used. As a technology for detecting abnormalities in mobile bodies and ground equipment, for example, multiple measurement devices are installed on trains and analysis is performed based on the obtained data. Technology. Here, after converting the data measured from the time series into the distance series, these data are consistent with the data given from the specified starting point, and the average of the data is taken from the distance series, and the measurement results obtained from multiple trains, if there is abnormal data If the...
