It should be noted that the terms "comprises" and "comprising," and any variations thereof, in the embodiments of the present application, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

The embodiment of the application discloses a learning method based on an intelligent mattress, the intelligent mattress and a storage medium, which can improve the interactivity between the intelligent mattress and children, are beneficial to improving the enthusiasm of the children for learning idioms on the intelligent mattress, and are beneficial to popularization and application of the intelligent mattress. The following detailed description is made with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic flowchart of a first embodiment of a learning method based on an intelligent mattress disclosed in the embodiment of the present application. As shown in fig. 1, the intelligent mattress-based learning method comprises the following steps:

101. the intelligent mattress detects a first part Chinese character combination contained in a certain idiom to be recognized output by the front display screen.

In this application embodiment, intelligent mattress can keep wireless communication with the place ahead display screen to be connected. After the front display screen enters the idiom learning mode, the front display screen can output a first part of Chinese character combinations contained in a certain idiom to be recognized randomly and send the randomly output first part of Chinese character combinations contained in the certain idiom to be recognized to the intelligent mattress, so that the intelligent mattress can detect the first part of Chinese character combinations contained in the certain idiom to be recognized output by the front display screen. For example, the front display screen may randomly output a first part of Chinese character combination "fox false" included in a certain idiom "fox pseudo-tiger" and send the first part of Chinese character combination "fox false" to the intelligent mattress, so that the intelligent mattress may detect the first part of Chinese character combination "fox false" included in the certain idiom "fox pseudo-tiger" output by the front display screen.

In some embodiments, the intelligent mattress can control the front display screen to enter the idiom learning mode while maintaining the wireless communication connection with the front display screen.

For example, the intelligent mattress detects any one of a plurality of areas on the upper surface of the intelligent mattress, which is pressed by a palm, as a selected area; acquiring a target image which is sent by a trusted device and is obtained by shooting a certain household device in the process that the trusted device is pressed by the palm in the selected area; and identifying the household equipment (the household robot) from the target image; identifying the current position of the household equipment placed in the process that the selected area is pressed by the palm; judging whether the area unique identifier of the selected area is the same as a target area unique identifier contained in a preset condition for triggering the front display screen to enter the idiom learning mode, and if so, judging whether the current position where the household equipment is placed is the same as the appointed visit position of the household equipment contained in the preset condition for triggering the front display screen to enter the idiom learning mode; if the two are the same, the front display screen is controlled to enter the idiom learning mode.

The implementation can conveniently control the front display screen to enter the idiom learning mode, and the situation that the front display screen enters the idiom learning mode by pressing the keys of the remote controller for many times is avoided, so that the front display screen can enter the idiom learning mode quickly.

For example, the trusted device may be an electronic device such as a mobile phone, a tablet, or a smart watch, and the embodiments of the present application are not limited thereto.

102. The intelligent mattress obtains the second part of Chinese character combination included in the idiom to be recognized from the database; the first part Chinese character combination and the second part Chinese character combination form the idiom to be recognized.

In some embodiments, the intelligent mattress can take the first part Chinese character combination as a search index, and search the second part Chinese character combination included in the to-be-recognized language from the database according to the search index. Illustratively, for example, the first part of Chinese character combination is "fox false", the intelligent mattress may use the first part of Chinese character combination "fox false" as a search index, and search a second part of Chinese character combination "tiger wei" included in the idiom "fox-tiger wei" from the database according to the search index.

103. The light projection module above the intelligent mattress control simultaneously projects a Chinese character combination to be selected on each of a plurality of areas on the upper surface of the intelligent mattress; the Chinese character combinations to be selected projected from any two of the regions are different from each other, and all the Chinese character combinations to be selected projected from the regions comprise the second part of Chinese character combinations.

In some embodiments, the intelligent mattress may be an intelligent mattress with inflation and deflation functions, and when the inflation amount of the intelligent mattress is different, the thickness of the intelligent mattress is also different. On this basis, the manner that the light projection module above the intelligent mattress control in the step 103 simultaneously projects a candidate chinese character combination on each of the plurality of regions of the upper surface of the intelligent mattress may be as follows:

the intelligent mattress detects the current inflation amount; for example, the intelligent mattress can directly read the current inflation amount of the intelligent mattress counted by the inflation device from the inflation device (such as an inflation valve);

the intelligent mattress judges whether the current inflation amount is lower than the standard inflation amount, if so, the air amount difference between the standard inflation amount and the current inflation amount is calculated; for example, the standard inflation amount may be a maximum allowable inflation amount of the smart mattress;

the intelligent mattress determines a light intensity change coefficient which is in a direct proportional relation with the air quantity difference according to the air quantity difference; that is, the greater the difference in the gas amount, the greater the light intensity variation coefficient; conversely, the smaller the air quantity difference is, the smaller the light intensity change coefficient is; wherein the light intensity variation coefficient is greater than 0 and less than 1;

the intelligent mattress determines the standard light intensity of the light projection module above the intelligent mattress corresponding to the standard inflation amount;

the intelligent mattress increases the standard light intensity of the light projection module according to the light intensity change coefficient to obtain the target light intensity;

the light projection module above the intelligent mattress is controlled by the intelligent mattress to project a Chinese character combination to be selected on each of a plurality of areas on the upper surface of the intelligent mattress according to the target light intensity.

In the real environment, the intensity that the light of projecting module above the intelligence mattress throws out light can decrease progressively along with the increase of distance, this is because the light has received the diffraction influence of particle in the real environment air, and the current inflation volume of intelligence mattress is less than standard inflation volume, and when the tolerance difference between this standard inflation volume and the current inflation volume is big more, the distance that the light of projecting module above the intelligence mattress throws out reachs the upper surface of intelligence mattress is also just more big, correspondingly, the intensity that the light of projecting module throws out according to standard light intensity decreases progressively more seriously, this makes the light throw and just take place the atomizing phenomenon on the upper surface of intelligence mattress more easily, lead to the chinese character combination of selecting that throws out on each region in these several regions to be fuzzy more.

In the embodiment of the present application, when the current inflation amount of the intelligent mattress is lower than the standard inflation amount, and the air amount difference between the standard inflation amount and the current inflation amount is larger (that is, the distance from the light projected by the light projection module above the intelligent mattress to the plurality of regions on the upper surface of the intelligent mattress is larger), the target light intensity obtained by adjusting the standard light intensity of the light projection module by the intelligent mattress is larger, therefore, the intensity of the light projected by the light projection module according to the target light intensity decreases progressively when reaching a plurality of areas on the upper surface of the intelligent mattress, the corresponding light is projected onto the plurality of areas on the upper surface of the intelligent mattress, the atomization phenomenon is difficult to occur, therefore, the Chinese character combinations to be selected projected on each of the plurality of areas are clearer, and the children can watch the clear Chinese character combinations to be selected projected on each area.

The light projection module may be a known laser projection module, and the embodiments of the present application are not described herein.

104. The intelligent mattress detects the target area selected from the plurality of areas.

105. The intelligent mattress identifies whether the second part of Chinese character combination is projected on the target area, if so, the step 106 is executed; if not, the flow is ended.

106. And the intelligent mattress outputs a lottery-drawing voice.

For example, assuming that the idiom to be recognized is "Huiwei", the quartic speech may be "Wa," the idiom of you has recognized "Huiwei", real wand, then Du! ".

Therefore, the intelligent mattress-based learning method shown in fig. 1 can improve the interactivity between the intelligent mattress and the child, thereby being beneficial to improving the enthusiasm of the child in learning idioms on the intelligent mattress, further being capable of improving the intelligent degree of the intelligent mattress, and further being beneficial to popularization and application of the intelligent mattress.

Referring to fig. 2, fig. 2 is a schematic flowchart of a second embodiment of the intelligent mattress-based learning method disclosed in the embodiment of the present application. As shown in fig. 2, the intelligent mattress-based learning method comprises the following steps:

201. the intelligent mattress obtains an interactive message sent by the trusted device, the interactive message at least comprises a unique identifier and a distance value of the front display screen, and the distance value is obtained when the distance between the trusted device and the front display screen is measured when the trusted device is located at a certain position in an indoor environment where the intelligent mattress is located and the front display screen.

In some embodiments, the trusted device may be located at a position in the indoor environment of the smart mattress, and the distance value between the trusted device and the front display screen may be obtained by ranging the distance between the trusted device and the front display screen using Ultra Wideband (UWB) technology. That is, when the trusted device is at a location in the indoor environment of the smart mattress, the distance between the trusted device and the front display distance as measured by the UWB technique by the trusted device is equal to the distance between the front display distance as measured by (e.g., as measured by) the front display and the trusted device.

202. The intelligent mattress takes the unique identifier of the front display screen as a basis to determine an initial agreed key agreed in advance by the intelligent mattress and the front display screen.

203. The intelligent mattress expands the initial agreed key according to the distance value to generate a key to be verified; and the front display screen expands the initial agreed key according to the distance value to generate a legal instant key.

In some embodiments, the smart mattress expands the initial engagement key according to the distance value, and generating the key to be verified may include the following steps:

the intelligent mattress determines the historical connection times of the intelligent mattress and the front display screen in a specified historical time period (such as the previous 72 hours);

the intelligent mattress identifies whether the historical connection times belong to positive integers smaller than the distance value; if so, acquiring a first quotient obtained by dividing the distance value by the historical connection times; and obtaining an integer part of the first quotient as a first quantity; for example, if the historical connection number is 3 and the distance value is 24cm, the first number is 8; for another example, if the historical connection number is 3 and the distance value is 22cm, the first number is 7;

the smart mattress inserts a first number of first extension characters in every two adjacent characters in the initial agreement key to generate a key to be verified.

In some embodiments, if the smart mattress determines that the first number is greater than the number of characters included in the initial engagement key, the method further comprises:

the intelligent mattress determines a certain character with the sequence number equal to the first number from all characters contained in the first key string as a first expanded character, and performs the step of inserting the first expanded character with the first number into every two adjacent characters in the initial agreement key so as to generate the key to be verified.

The method for generating the legal instant key by expanding the initial agreed key according to the distance value is the same as the method for generating the key to be verified by expanding the initial agreed key according to the distance value by the intelligent mattress, and the detailed description is omitted here.

204. The intelligent mattress sends a wireless connection request at least comprising the key to be verified to the front display screen according to the unique identifier of the front display screen, so that the front display screen establishes wireless connection with the intelligent mattress when receiving the wireless connection request and verifying that the key to be verified is consistent with a legal instant key.

Implementing the step 201 to the step 204, the intelligent mattress can expand the initial agreed key according to the distance value to generate a key to be verified; moreover, the front display screen expands the initial agreed key according to the distance value to generate a legal instant key; and the front display screen establishes wireless connection with the intelligent mattress when the key to be verified is verified to be consistent with the legal instant key. Therefore, the implementation of the steps 201 to 204 enables the legal key of the intelligent mattress to be accessed to the front display screen to be not fixed any more, but to be dynamically changed according to the distance value, which is beneficial to improving the reliability of the intelligent mattress to be accessed to the front display screen.

205. The intelligent mattress detects a first part Chinese character combination contained in a certain idiom to be recognized output by the front display screen.

206. The intelligent mattress obtains the second part of Chinese character combination included by the idiom to be identified from the database; the first part of Chinese character combination and the second part of Chinese character combination form the idiom to be recognized.

207. The light projection module above the intelligent mattress control simultaneously projects a Chinese character combination to be selected on each of a plurality of areas on the upper surface of the intelligent mattress; the Chinese character combinations to be selected projected from any two of the regions are different from each other, and all the Chinese character combinations to be selected projected from the regions comprise the second part of Chinese character combinations.

The implementation manner of step 207 may refer to the implementation manner of step 103, and will not be repeated here.

208. The intelligent mattress detects the target area selected from the plurality of areas.

209. The intelligent mattress identifies whether the second part of Chinese character combination is projected on the target area, if so, the step 210 is executed; if not, the flow is ended.

210. And the intelligent mattress outputs a lottery-drawing voice.

Therefore, the intelligent mattress-based learning method shown in fig. 2 can improve the interactivity between the intelligent mattress and the child, thereby being beneficial to improving the enthusiasm of the child in learning idioms on the intelligent mattress, further being capable of improving the intelligent degree of the intelligent mattress, and further being beneficial to popularization and application of the intelligent mattress.

Referring to fig. 3, fig. 3 is a schematic flowchart of a learning method based on an intelligent mattress according to a third embodiment of the present application. As shown in fig. 3, the intelligent mattress-based learning method comprises the following steps:

312. And the intelligent mattress sends an idiom commentary video acquisition request containing the idiom to be recognized to the learning platform.

313. And the intelligent mattress obtains the idiom comment video corresponding to the idiom to be recognized, which is sent by the learning platform.

314. And the intelligent mattress pushes the idiom comment video corresponding to the idiom to be recognized to the trusted equipment.

Wherein, the implementation of the steps 311 to 312 is beneficial to improving the mastering level of the children on the idiom to be recognized.

In some embodiments, the idiom to be recognized may be an animal-related idiom, such as "tiger fox", "crane chicken flock", "chicken dog stealer", "snipe clam war", "snake mouse nest", and the like; correspondingly, after the intelligent mattress pushes the idiom commentary video corresponding to the idiom to be recognized to the trusted device, the learning method based on the intelligent mattress shown in fig. 3 may further include the following steps:

a first obtaining unit 402, configured to obtain a second part of chinese character combinations included in the to-be-recognized phrase from the database; the first part of Chinese character combination and the second part of Chinese character combination form the idiom to be recognized;

the first control unit 403 is used for controlling the upper light projection module to project a Chinese character combination to be selected on each of a plurality of areas on the upper surface of the intelligent mattress; the Chinese character combinations to be selected projected from any two of the regions are different from each other, and all the Chinese character combinations to be selected projected from the regions comprise the second part of Chinese character combinations;

In some embodiments, the intelligent mattress can be an intelligent mattress with inflation and deflation functions, and when the inflation amount of the intelligent mattress is different, the thickness of the intelligent mattress is also different. On this basis, the manner that the first control unit 403 controls the upper light projection module to project a candidate chinese character combination on each of the plurality of regions of the upper surface of the intelligent mattress at the same time may be as follows:

the first control unit 403 detects its current inflation amount; for example, the intelligent mattress can directly read the current inflation amount of the intelligent mattress counted by the inflation device from the inflation device (such as an inflation valve);

the first control unit 403 judges whether the current inflation amount is lower than the standard inflation amount, and if so, calculates the air amount difference between the standard inflation amount and the current inflation amount; for example, the standard inflation amount may be a maximum allowable inflation amount of the smart mattress;

the first control unit 403 determines a light intensity variation coefficient in direct proportion to the air volume difference according to the air volume difference; that is, the greater the difference in the gas amount, the greater the light intensity variation coefficient; conversely, the smaller the air quantity difference is, the smaller the light intensity change coefficient is; wherein the light intensity variation coefficient is greater than 0 and less than 1;
