摘要

An information processing system includes a terminal apparatus that receives machine-type identification information identifying a machine type of a monitoring target apparatus and state history information indicating a history of a state of the monitoring target apparatus, from the monitoring target apparatus by near field communication, and that sends the received machine-type identification information and state history information, an information processing apparatus that receives the machine-type identification information and the state history information from the terminal apparatus, and a storage apparatus that accumulates machine-type identification information identifying a machine type of a monitoring target apparatus and normal-state history information in an associated manner, the normal-state history information being the state history information when the machine type is in a normal state. When the information processing apparatus receives the machine-type identification information and state history information about a certain monitoring target apparatus from the terminal apparatus, the information processing apparatus compares the normal-state history information accumulated in the storage apparatus in association with the machine-type identification information and the received state history information, judges whether an operation state of the monitoring target apparatus is normal, and sends a judgment result to the terminal apparatus. The terminal apparatus receives the judgment result from the information processing apparatus, and displays the received judgment result.
