The present invention relates to a home appliance diagnosis system and to a diagnosis method for same, and more particularly, to a home appliance diagnosis system and to a diagnosis method for same, which involve receiving product information on the home appliance, which is outputted in a predetermined signal form from the home appliance, and analyzing the received product information to check the condition of the home appliance and to diagnose faults in the home appliance. According to the present invention, a diagnosis server easily extracts product information from a signal, and improves the accuracy of the product information through a multi-stage verification process when the diagnosis server outputs product information from the signal received thereat to diagnose the home appliance, to thereby achieve improved accuracy and reliability of the result of the diagnosis based on the product information.

Home appliance diagnosis system and diagnosis method for same

A home appliance system and an operation method thereof are disclosed. The home appliance outputs product information as a predetermined sound and transmits the sound through a connected communication network, thereby making it easier for a service center at a remote place to check a status of the home appliance. Further, the home appliance system and operation method thereof prevents noise or signal error generated in the procedure of converting product information into a signal of a predetermined frequency band in order to output the product information as a sound, thus enabling stable signal conversion and improving the accuracy of information transmission using the output of sound.

Home appliance, home appliance system, and diagnosis method of a home appliance

A system and method for diagnosing a home appliance are disclosed. The home appliance outputs product information as a predetermined sound signal, and transmits the sound signal to a service center of a remote site over a communication network, such that a service technician of the service center can easily check a current status of the home appliance. The diagnostic system effectively detects data using multiple synchronous signals having a time difference, quickly diagnoses a current status or fault of the home appliance, provides a service for more correctly diagnosing a faulty operation of the home appliance, and increases user satisfaction and reliability.

System and method for diagnosing home appliance

A home appliance and home appliance system are provided which enable a portable terminal not to recognize an acoustic signal sound corresponding to product information output by the home appliance as noise. Thus, the acoustic signal corresponding to product information output by the home appliance may be transmitted to a service center through the portable terminal. The home appliance may include a controller that sets a dead time at a predetermined interval of time with respect to a signal corresponding to product information to avoid a noise detection section of a portable terminal, a converter that converts the signal into an acoustic signal of a predetermined band, and a sound output device that outputs the acoustic signal as sound.

Home appliance and home appliance system

A system and method for diagnosing a home appliance are disclosed. The home appliance outputs product information as a predetermined sound signal, and transmits the sound signal to a service center of a remote site over a communication network, such that a service technician of the service center can easily check a current status of the home appliance. When a diagnostic server of the service center analyzes the sound signal of the home appliance, it selects a plurality of preamble candidates and can effectively and correctly detect data using weights, so that it can quickly diagnose a faulty operation of the home appliance. An erroneous data analysis and its associated erroneous diagnosis are prevented, so that the diagnostic system provides a service for more correctly diagnosing a faulty operation of the home appliance and also increases user satisfaction and reliability of the home appliance.
