Abstract: An anomaly detection electronic controller performs anomaly detection processing and is connected to a network, which a plurality of electronic controllers uses for communication. The anomaly detection electronic controller includes an anomaly detection processor that performs anomaly detection processing regarding a data frame. The anomaly detection controller also includes an anomaly detection processing requester that decides an anomaly detection processing timing when receiving the data frame, the anomaly detection processing timing being a reception timing of one or multiple fields in the data frame. The anomaly detection processor further performs the anomaly detection processing regarding the data frame at the anomaly detection processing timing decided by the anomaly detection processing requester.

Abstract: A data providing method is carried out by a computer (460) built in a data processing system (1) which is designed to collect log information from electronic devices through a network (30) and provide services based on that log information for authenticated users. The data providing method includes: receiving an air conditioner (102a, 102b)'s log information through the network; generating display data by reference to pieces of information which are included in the air conditioner's log information and which indicate (i) a preset temperature of the air conditioner, (ii) an outdoor temperature outside a living space in which the air conditioner is installed, and (iii) an indoor temperature of the living space in which the air conditioner is installed, the display data representing a trend of change of a turnaround time that indicates how long it takes from when the air conditioner starts operating until the indoor temperature reaches the preset temperature; and providing the display data for an authenticated user's display terminal (130a, 130b).
