Problems solved by technology

[0005] However, there are certain problems in the existing fingerprint identification, which are mainly manifested in: (1) The fingerprint must be pre-entered and stored in the fingerprint database. The method of traversing the entire fingerprint database is low in recognition efficiency; (2) due to fingerprint image noise and scar interference, fingerprint features are not obvious, and it is difficult to extract accurate and reliable minutiae; on the other hand, using the minutiae local structure Information similarity to find registration reference detail point pairs, because it is local information, there are completely mismatched reference detail point pairs, and their local structure information similarity is very high, so this pair of detail points will be mistakenly used for registration Accurate, resulting in the final wrong matching judgment, the recognition accuracy is low
This undoubtedly reduces the efficiency of child lock fingerprint identification

Embodiment Construction

[0020] The present invention will be described in detail below in conjunction with examples, which are only preferred implementations of the present invention, and are not limitations of the present invention.

[0021] A method for controlling a disinfection cabinet using a fingerprint child lock, characterized in that it comprises the steps of:

[0022] S1. Collect the user's fingerprint input and obtain the fingerprint image to be recognized.

[0023] The present invention does not specifically limit the method for collecting the user's fingerprint input, as long as the user's fingerprint image can be collected. Preferably, the fingerprint image of the user can be collected by a sensor, wherein the mentioned sensor includes but is not limited to an optical fingerprint sensor and a semiconductor fingerprint sensor, more preferably a semiconductor fingerprint sensor is used to collect the user's fingerprint image, the imaging principle of the semiconductor fingerprint sensor i...

Abstract

The invention discloses a method for utilizing a fingerprint children lock to control a disinfection cabinet. The method comprises the steps of 1, acquiring fingerprint input of a user and obtaining afingerprint image to be recognized; 2, obtaining fingerprint characteristics of the fingerprint image; 3, judging whether following conditions are satisfied or not: 1), whether the fingerprint line spacing in the fingerprint characteristics is larger than a preset numerical value or not and 2), whether the contact time of fingerprints pressed in a fingerprint acquiring area is larger than a preset pressing time threshold value or not; if the condition 1 or condition 2 is satisfied, disenabling the children lock function so that a cabinet door of the disinfection cabinet can be normally opened. Fingerprints do not need to be input and stored in a fingerprint library, the fingerprint line spacing in the fingerprint characteristics and the contact time of the fingerprints pressed in the fingerprint acquiring area are used as important means of enabling and disenabling the children lock, therefore whether to disable the children lock function or not is determined, and the problem that children operate the disinfection cabinet by mistake can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of biological identification, in particular to a method for controlling a disinfection cabinet by using a fingerprint child lock. Background technique [0002] At present, there are many microorganisms that transmit intestinal diseases, and the bacteria that often cause acute diarrhea include pathogenic Escherichia coli, Salmonella, Shigella, Vibrio cholerae, and Bacillus cereus. Most of these bacteria can die after being subjected to high temperature at 100°C for 1-3 minutes or heated at 80°C for 10 minutes. If the heating temperature is 56°C, these bacteria can still survive after heating for 30 minutes. Therefore, it is very important to maintain food hygiene and prevent diseases from entering the mouth. [0003] As a common electrical appliance in modern homes or service structures, disinfection cabinets can disinfect tableware and daily necessities and keep them hygienic. It plays a great role in maint...
