Abstract: A diagnostic apparatus determines, for an element in a diagnostic element table, whether log information stored in a log storing unit satisfies a predetermined condition, the element indicating that a failure symptom can be diagnosed provided that the log information satisfies the predetermined condition, changes, based on a result of the determination, the element in the diagnostic element table to indicate the failure symptom can be diagnosed or cannot be diagnosed, the element originally indicating that the failure symptom can be diagnosed provided that the log information satisfies a predetermined condition, calculates a diagnostic priority of a plurality of operating conditions based on the statistical information and the changed diagnostic element table, and outputs information based on an operating condition, among a plurality of operating conditions, having the diagnostic priority satisfying the predetermined condition.

Abstract: A server receives identification information for identifying an equipment and operating information of the equipment corresponding to a predetermined time, permitting a terminal device, if it is determined that the received operating information satisfies a predetermined condition, to refer to log information of the equipment accumulated in the server, the log information corresponding to the identification information corresponding to a time before the predetermined time, and not permitting the terminal device, if it is determined that the received operating information does not satisfy the predetermined condition, to refer to the log information of the equipment accumulated in the server. The predetermined condition is that the predetermined time is included in a predetermined standard period ending at a current time and the received operating information matches operating information included in the log information of the equipment corresponding to a time in the standard period and accumulated in the server.

Abstract: A failure diagnosis device includes a communication unit, a data comparison unit, and an eligibility determination unit. The communication unit acquires first physical quantity data and second physical quantity data of a type different from that of the first physical quantity data that are used for performing failure diagnosis of a home appliance acquired by a sensor unit, and first control information related to the second physical quantity data acquired by the home appliance. The data comparison unit compares the second physical quantity data with the first control information. The eligibility determination unit determines whether or not the first physical quantity data is eligible as data used for the failure diagnosis based on a comparison result obtained by the data comparison unit.

Abstract: A diagnosis method includes giving an instruction to present at least two sound collection positions of an abnormal sound of an electric apparatus to an outside; comparing a current position of the diagnosis device and one sound collection position of the at least two sound collection positions; obtaining sound data indicative of an abnormal sound of the electric apparatus collected by a microphone, based on a comparison result and storing the sound data in a sound data storage portion so as be correlated with log data and the one sound collection position; and diagnosing an abnormal sound of the electric apparatus by using at least two items of sound data and at least two sound collection positions, based on a determination result whether sound collection is completed and a determination result whether diagnosis of an abnormal sound is possible.
