Home appliance diagnosis system and diagnosis method for same
First Claim
1. A diagnosing server, comprising:
- a displaying unit that displays information including a diagnosis progressing state or diagnosis result;
a data storing unit that stores diagnosis data for diagnosis and the diagnosis result;
a sound receiving unit that receives a signal, through a predetermined communication network, including product information including at least one of an identification information of a home appliance, setting information, operation information, or mal-function information, which is output from the home appliance;
a sound recording unit that records the signal received through the sound receiving unit;
a signal processing unit that inversely extracts the product information from the signal recorded by the sound recording unit; and
a diagnosing unit that analyzes the product information, diagnoses a state or failure of the home appliance, and produces a diagnosis result, wherein the signal processing unit detects a start point of a preamble representing a start of the product information and a frequency of the signal, detects the preamble through pattern matching, performs demodulation and decoding on any one of a plurality of frames constituting the product information with respect to the preamble, and detects an error of the preamble, wherein the signal processing unit compensates for an error occurring during a transmission process by setting a predetermined section before and after a position of the preamble as a preamble start area, and wherein the diagnosing server transmits the diagnosis result to a user terminal and/or a repair person terminal.

Abstract
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.

13. A diagnosis system, comprising:
-
a home appliance that outputs as a signal sound, product information including at least one of identification information, setting information, operation information, or mal-function information; a diagnosing server that extracts the product information from a received signal of the home appliance to diagnose the home appliance and produces a diagnosis result on a state or failure of the home appliance; and a user terminal that transmits the signal sound to the diagnosing server through a telephone network or a mobile communication network, wherein the diagnosing server detects a start point of a preamble representing a start of the product information and a frequency of the signal, detects the preamble through pattern matching, performs demodulation and decoding on any one of a plurality of frames constituting the product information with respect to the preamble, and detects an error of the preamble, wherein the diagnosing server comprises a signal processor that inversely extracts the product information from the signal recorded by a sound recorder, and wherein the signal processor compensates for an error occurring during a transmission process by setting a predetermined section before and after a position of the preamble as a preamble start area, and wherein the diagnosing server transmits the diagnosis result to the user terminal and/or a repair person terminal.
