Household appliance code graph with time limit function and generating and identifying method thereof

Abstract

The invention provides a household appliance code graph with a time limit function. The household appliance code graph comprises code information with use time limit instructions, and the code information records the effective time use interval value of the household appliance code graph. The generating method of the household appliance code graph with the time limit function comprises inputting the code information containing the use time limit instructions in a household appliance code graph generating interface; by combining with a household code graph generating base, generating and uploading the code information into the household appliance code graph with the household appliance code graph with the time limit function into a cloud server. The identifying method of the household appliance code graph with the time limit function comprises identifying the current household code graph twice to obtain the time use interval information of the household appliance code graph; after the time use interval information is compared with the effective time use interval value, determining whether the household code graph is still an effective household code graph during the second identification. The household appliance code graph with the time limit function can be used only within an effective time range, thereby avoiding illegal application of the household code graph by counterfeiters.

Description

technical field [0001] The invention relates to an anti-counterfeit code map, in particular to a home appliance code map with a time-limiting function, a generation method and a reading method thereof. Background technique [0002] At present, the existing home appliance code maps generally do not have the function of limiting the use time. Therefore, the home appliance code maps are easily used illegally by counterfeiters. Contents of the invention [0003] Aiming at the deficiencies in the above problems, the present invention provides a home appliance code map that can only be used within a valid time range, so as to prevent the home appliance code map from being illegally used by counterfeiters. The home appliance code map with time-limited function and its generation method and method of reading. [0004] In order to achieve the above object, the present invention provides a home appliance code map with a time-limiting function, in which code information with a use t...
