The present invention relates to a maintenance management system, method, and program for electrical equipment that can reduce the complexity of trouble repairing electrical equipment in both administrative departments and can be speeded up.

  Conventionally, when various home appliances such as electric refrigerators, electric washing machines, microwave ovens, PCs, etc. have failed, customers have different inquiries depending on the manufacturer and model, so where to call for repairs It is common to check the contact information by looking at the instruction manual and so on.

  On the other hand, in the maintenance management department that has received an inquiry from a customer, the inquiry information is transmitted to a predetermined department by telephone, so that the customer's repair request is dealt with.

  Therefore, in order to respond quickly to fault repairs, home appliances are connected via a local home network, self-diagnosis for each home appliance is performed, and self-diagnostic results are obtained for maintenance of the home appliance manufacturer. A home master that periodically transmits data over a wide area network is provided, and the manufacturer performs periodic analysis of home appliances by performing analysis of failure and operation, cause analysis, and selection of countermeasures from received maintenance data. In the case where an inspection can be performed and a failure or an operation or more occurs, there are those that can be automatically handled (for example, see Patent Document 1).

  In addition, the self-diagnosis result is received by the mobile phone using infrared rays from the self-diagnosis means provided in the electrical equipment, and the self-diagnosis result is transmitted to the maintenance service server via the communication line. By providing parts estimation, repair contractor selection, parts inventory and date of acquisition, repair delivery date determination, repair cost determination, service cost estimation and repair timing information service to customers (For example, refer to Patent Document 2).
