detailed description

Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

The following describes the dishwasher and its control method according to the embodiments of the present invention with reference to the accompanying drawings.

In order to ensure the safety of home appliances, users need to frequently set "lock" settings on home appliances and the problem that the safety of home appliances is reduced because users often forget to "lock" settings, the embodiment of the present invention proposes a dishwasher control The method includes: receiving a user's trigger operation; obtaining the user's fingerprint information according to the trigger operation, and judging whether the fingerprint information belongs to the authorized user; if the fingerprint information belongs to the authorized user, executing an operation instruction corresponding to the trigger operation.

FIG. 1 is a flowchart of a dishwasher control method according to an embodiment of the present invention.

As shown in Figure 1, the dishwasher control method includes:

S101. Receive a user's trigger operation.

For example, after a user finishes eating, he puts the tableware into the dishwasher, and presses the "Daily Wash" button on the dishwasher control interface. At this time, the dishwasher receives a user's trigger operation.

S102. Obtain the fingerprint information of the user according to the trigger operation, and determine whether the fingerprint information belongs to the authorized user.

The specific process, as shown in Figure 2, first uses the fingerprint collector to collect the user's fingerprint image. Wherein, the fingerprint collector can be set on all the buttons of the dishwasher control interface, and when the user performs a trigger operation on any button, the dishwasher can collect the user's fingerprint image through the fingerprint collector on the button. A fingerprint collection interface with a fingerprint collector can also be set on the dishwasher, and when the dishwasher receives the user's trigger operation on the buttons, it will remind the user to input fingerprint information by voice. After hearing the voice reminder, the user inputs fingerprint information on the fingerprint collection interface, and the fingerprint collector on the fingerprint collection interface can collect the user's fingerprint image.

When the user performs a trigger operation or inputs fingerprint information, because the user's finger is too dry, too wet, peeled or the pressure is not enough, the collected fingerprint image will be mixed with noise, which will reduce the quality of the fingerprint image. Therefore, in order to facilitate the feature extraction of the fingerprint image and improve the recognition degree of the fingerprint image, after the fingerprint image is collected by the fingerprint collector, the collected fingerprint image is preprocessed. Wherein, the manner of preprocessing includes but not limited to compression, detection, quality judgment, image refinement, image enhancement and so on.

It can be understood that, when preprocessing the fingerprint image, one or more preprocessing methods can be selected for preprocessing according to the specific conditions of the collected fingerprint image. For example, if the collected fingerprint image is not clear enough, the fingerprint image can be processed by means of image enhancement preprocessing to improve the clarity of the fingerprint image.

After the fingerprint image is preprocessed, the ridge line data of the preprocessed fingerprint image is extracted. Then, the fingerprint features of the preprocessed fingerprint image are obtained according to the extracted ridge data, such as the starting point, ending point, joint point, intersection point, etc. of the ridge line.

After the fingerprint features of the preprocessed fingerprint image are obtained, the obtained fingerprint features are sequentially matched with the fingerprint features in the fingerprint database. Specifically, by calculating the similarity between the fingerprint feature of the preprocessed fingerprint image and the fingerprint feature in the fingerprint database, according to whether the similarity between the two exceeds a preset threshold, it can be judged that the fingerprint feature is consistent with the fingerprint in the fingerprint database. Whether the features match.

Wherein, the authorized user refers to the user who has entered the fingerprint information into the fingerprint database, so that he has the right to use the dishwasher. For example, a user can upload fingerprint information to a fingerprint database through an APP that controls a dishwasher.

If the similarity between the fingerprint feature of the preprocessed fingerprint image and a certain fingerprint feature in the fingerprint database exceeds a preset threshold such as 90%, that is, the fingerprint feature of the preprocessed fingerprint image matches a certain fingerprint feature in the fingerprint database , it can be determined that the fingerprint information belongs to the authorized user.

If the similarity between the fingerprint feature of the preprocessed fingerprint image and a certain fingerprint feature in the fingerprint database does not exceed 90% of the preset threshold, then the fingerprint feature of the preprocessed fingerprint image is sequentially compared with the next fingerprint in the fingerprint database. features to match. If the similarity between the fingerprint feature of the preprocessed fingerprint image and the fingerprint feature in the fingerprint database does not exceed 90% of the preset threshold, then the fingerprint feature of the preprocessed fingerprint image will be compared with the fingerprint feature in the fingerprint database in turn. The next fingerprint feature is matched until a matching fingerprint feature is encountered. If the fingerprint features of the preprocessed fingerprint image do not match all the fingerprint features in the fingerprint database, that is to say, none of the similarity values exceeds the preset threshold, it means that the fingerprint information does not belong to the authorized user.

S103, if the fingerprint information belongs to the authorized user, execute an operation instruction corresponding to the trigger operation.

If the fingerprint information belongs to the authorized user, the dishwasher executes the operation instruction corresponding to the user's trigger operation "daily washing" to perform "daily washing" on the tableware.

If the fingerprint information does not belong to the authorized user, that is, when the user is not an authorized user, the dishwasher refuses to execute the operation instruction corresponding to the trigger operation, and at the same time makes a voice broadcast such as "You do not have the right to use it" to prevent the user from using it without the right to use it. The user or authorized user acts as a reminder.

For example, a child touches an operating button on a dishwasher out of curiosity. After judging, the dishwasher concludes that the child's fingerprint information does not belong to the authorized user, and refuses to execute the instruction corresponding to the operation button, thus avoiding the occurrence of safety accidents. At the same time, the voice broadcast of the dishwasher can make the parents keep the child away from the dishwasher in time after hearing the voice broadcast, which further improves the safety of the dishwasher.

It can be seen that, compared with the prior art, the technical solution proposed by the present invention judges whether the user is an authorized user through fingerprint identification, and if the user is an authorized user, then executes the corresponding operation instruction of the trigger operation, and if not an authorized user, then does not execute , operation method, high security.

In summary, the dishwasher control method according to the embodiment of the present invention obtains the user's fingerprint information according to the user's trigger operation, and judges whether the fingerprint information belongs to an authorized user, and if it belongs to an authorized user, then executes the operation corresponding to the trigger operation Instructions, that is to say, when it is judged that the fingerprint information belongs to an authorized user through fingerprint identification, then the operation instruction is executed, so that the user does not need to set the dishwasher cumbersomely to "lock the machine" to avoid misoperation, and the operation is convenient , High security.

The dishwasher proposed by the embodiment of the present invention will be described below with reference to FIG. 3 . Fig. 3 is a schematic structural view of a dishwasher according to an embodiment of the present invention.

As shown in FIG. 3 , the dishwasher may include: a receiving module 310 , a processing module 320 , and an executing module 330 .

The receiving module 310 is used for receiving a user's trigger operation.

For example, after a user finishes eating, he puts the tableware into the dishwasher, and presses the "Daily Wash" button on the dishwasher control interface. At this time, the receiving module 310 receives a user's trigger operation.

The processing module 320 is used to acquire the fingerprint information of the user according to the trigger operation, and determine whether the fingerprint information belongs to the authorized user.

As shown in FIG. 4 , the processing module 320 may include: a collection unit 321 , a preprocessing unit 322 , an extraction unit 323 , a matching unit 324 , and a determination unit 325 .

Wherein, the collection unit 321 is used to obtain the user's fingerprint image through the fingerprint collector.

The preprocessing unit 322 is used for preprocessing the fingerprint image.

The matching unit 324 is used to match the fingerprint features with the fingerprint features in the fingerprint database.

The determining unit 325 is configured to determine that the fingerprint information belongs to the authorized user if they match; if not, determine that the fingerprint information does not belong to the authorized user.

The specific process, as shown in FIG. 2 , first uses the collection unit 321 to collect the user's fingerprint image. Wherein, the fingerprint collector can be set on all the buttons of the dishwasher control interface, and when the user performs a trigger operation on any button, the dishwasher can collect the user's fingerprint image through the fingerprint collector on the button. A fingerprint collection interface with a fingerprint collector can also be set on the dishwasher, and when the dishwasher receives the user's trigger operation on the buttons, it will remind the user to input fingerprint information by voice. After hearing the voice reminder, the user inputs fingerprint information on the fingerprint collection interface, and the fingerprint collector on the fingerprint collection interface collects the user's fingerprint image.

When the user performs a trigger operation or inputs fingerprint information, because the user's finger is too dry, too wet, peeled or the pressure is not enough, the collected fingerprint image will be mixed with noise and the quality of the fingerprint image will be reduced. Therefore, in order to facilitate the feature extraction of the fingerprint image and improve the recognition degree of the fingerprint image, after the fingerprint image is collected by the fingerprint collector, the preprocessing unit 322 preprocesses the collected fingerprint image. Wherein, the manner of preprocessing includes but not limited to compression, detection, quality judgment, image refinement, image enhancement and so on.

It can be understood that, when performing preprocessing on the fingerprint image, the preprocessing unit 322 may select one or more preprocessing methods to perform preprocessing according to the specific conditions of the collected fingerprint image. For example, if the collected fingerprint image is not clear enough, the fingerprint image can be processed by means of image enhancement preprocessing to improve the clarity of the fingerprint image.

After preprocessing the fingerprint image, the extracting unit 323 extracts the ridge line data of the preprocessed fingerprint image. Then, the fingerprint features of the preprocessed fingerprint image are obtained according to the extracted ridge data, such as the starting point, ending point, joint point, intersection point, etc. of the ridge line.

After obtaining the fingerprint features of the preprocessed fingerprint image, the matching unit 324 may sequentially match the obtained fingerprint features with the fingerprint features in the fingerprint database. Specifically, by calculating the similarity between the fingerprint feature of the preprocessed fingerprint image and the fingerprint feature in the fingerprint database, according to whether the similarity between the two exceeds a preset threshold, it can be judged that the fingerprint feature is consistent with the fingerprint in the fingerprint database. Whether the features match.

Wherein, the authorized user refers to the user who has entered the fingerprint information into the fingerprint database, so that he has the right to use the dishwasher. For example, a user can upload fingerprint information to a fingerprint database through an APP that controls a dishwasher.

If the similarity between the fingerprint feature of the preprocessed fingerprint image and a certain fingerprint feature in the fingerprint database exceeds a preset threshold such as 90%, that is, the fingerprint feature of the preprocessed fingerprint image matches a certain fingerprint feature in the fingerprint database , the determining unit 325 may determine that the fingerprint information belongs to an authorized user.

If the similarity between the fingerprint feature of the preprocessed fingerprint image and a certain fingerprint feature in the fingerprint database does not exceed 90% of the preset threshold, then the fingerprint feature of the preprocessed fingerprint image is sequentially compared with the next fingerprint in the fingerprint database. features to match. If the similarity between the fingerprint feature of the preprocessed fingerprint image and the fingerprint feature in the fingerprint database does not exceed 90% of the preset threshold, then the fingerprint feature of the preprocessed fingerprint image will be compared with the fingerprint feature in the fingerprint database in turn. The next fingerprint feature is matched until a matching fingerprint feature is encountered. If the fingerprint features of the preprocessed fingerprint image do not match all the fingerprint features in the fingerprint database, that is to say, none of the similarity values exceeds the preset threshold, the determining unit 325 may determine that the fingerprint information does not belong to an authorized user.

The execution module 330 is configured to execute an operation instruction corresponding to the trigger operation if the fingerprint information belongs to an authorized user.

If the fingerprint information belongs to an authorized user, the execution module 330 executes the operation instruction corresponding to the user's trigger operation "daily washing" to perform "daily washing" on the tableware.

As shown in FIG. 5 , the dishwasher may further include: a rejection module 340 .

The rejection module 340 is configured to reject the operation instruction corresponding to the trigger operation if the fingerprint information does not belong to the authorized user.

If the fingerprint information does not belong to the authorized user, that is, when the user is not an authorized user, then the rejection module 340 refuses to execute the operation instruction corresponding to the trigger operation, and at the same time makes a voice broadcast such as "You do not have the right to use it", so as to prevent the user from using the user without the right to use it. The user or authorized user acts as a reminder.

For example, a child touches an operating button on a dishwasher out of curiosity. After judging, the dishwasher concludes that the child's fingerprint information does not belong to the authorized user, and refuses to execute the instruction corresponding to the operation button, thus avoiding the occurrence of safety accidents. At the same time, the voice broadcast of the dishwasher can make the parents keep the child away from the dishwasher in time after hearing the voice broadcast, which further improves the safety of the dishwasher.

To sum up, the dishwasher according to the embodiment of the present invention obtains the user’s fingerprint information according to the user’s trigger operation, and judges whether the fingerprint information belongs to an authorized user, and if it belongs to an authorized user, then executes the operation instruction corresponding to the trigger operation, The user does not need to set the dishwasher cumbersomely to "lock the machine" to avoid misoperation, and the operation is convenient and safe.
