A plurality of data output apparatuses () are installed at places different from each other, and each output data in wireless communication. A data storage apparatus () stores the data output from the data output apparatus (). The data output apparatus () includes at least one sensor and a wireless communication apparatus. The wireless communication apparatus stores, for each of the plurality of other wireless communication apparatuses that can be a transmission destination of the data, connection information for connecting to the other wireless communication apparatus and priority information indicating a priority of the other wireless communication apparatus. Then, the wireless communication apparatus repeats processing of reading the connection information, and performing communication by using the read connection information in descending order of the priority until the communication succeeds when a transmission route of the data is set.

Data collection system, data output apparatus, and data collection method

A vibration processing apparatus () includes: an acquisition unit () that reads, from a vibration information storage unit (), information needed for detecting an abnormality in a belt conveyor (), the information being, for example, first detection data indicating a result of detecting a vibration at a first point of the belt conveyor (), and second detection data indicating a result of detecting a vibration at a second point on a downstream side of the first point of the belt conveyor (); and a determination unit () that determines that an abnormality occurs in the belt conveyor with a necessary condition or a necessary and sufficient condition that a result of comparing the first detection data and the second detection data satisfies a first reference.
