At the same time, the term "and / or" used in this specification includes any and all combinations of the relevant listed items.

[0057] The food preservation control method provided in the embodiment of the present application is used to perform relevant control during the process of preserving food by a food preservation device. Among them, the food preservation device refers to a device or object that can be used to preserve food, such as a refrigerator, a vacuum preservation cabinet or others. The food preservation control method can be executed by a controller of the food preservation device, and can also be executed by a terminal or server that is communicatively connected to the physical preservation device. Among them, the terminal can be but is not limited to various personal computers, laptops, smart phones, tablet computers, Internet of Things devices, portable wearable devices, etc. The server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services.

[0058] In one embodiment, a food preservation control method is provided, and the food preservation control method is executed by a controller in a food preservation device as an example. Figure 1 As shown, the food preservation control method comprises the following steps:

[0059] Step 102, after the food is put into the food preservation device, obtain the timing duration.

[0060] Wherein, the type of food preservation device is not limited, for example, it can be a refrigerator. After food is put into the food preservation device, the food preservation device preserves the food.

[0061] The types of timing durations are not unique. For example, the timing duration may be a reminder duration, which indicates the time required for the user to trigger a reminder. Alternatively, the timing duration may be a shelf life duration, which indicates the maximum time that food does not spoil. Alternatively, the timing duration may be an optimal use duration, which indicates the recommended time for the food to remain in a good quality state.

[0062] The value of the timing duration is not unique. For example, the timing duration can be a default duration, which can be determined in combination with the types of food stored in the food storage device, or a recommended fixed value. Therefore, there is no need to set the timing duration every time, which can simplify the use process. Alternatively, the timing duration can also be a duration set by the user, so that the timing duration can meet the personalized needs of the user.

[0063] When the timing duration is a duration set by the user, the user can set the timing duration through the interactive device. The interactive device is connected to the controller and can send the received timing duration set by the user to the controller so that the controller obtains the timing duration.

[0064] Step 104, obtaining the storage location of the food in the food storage device.

[0065] In a food storage device, there may be one or more storage locations. Taking a refrigerator as an example, the storage locations of the refrigerator include a refrigeration area and a freezing area. Food is refrigerated in the refrigeration area and frozen in the freezing area. When food is placed in different storage locations, it can be stored in the corresponding environment.

[0066] The food can be located by obtaining the storage position of the food in the food storage device. There is not only one way to obtain the storage position of the food in the food storage device. For example, the food in the storage position can be detected by a food detection device to obtain the storage position of the food in the food storage device. Alternatively, the controller can also obtain the storage position of the food in the food storage device by receiving a user instruction. Taking the food storage device as a refrigerator as an example, after receiving a user instruction representing a refrigeration reminder, the controller can determine that the storage position of the food in the food storage device is the refrigerator.

[0067] Step 106: When the storage time of the food in the food storage device reaches the timed time, a corresponding prompt message is issued based on the timed time and the storage location.

[0068] After the food is put into the food storage device, the controller starts to time the storage time of the food. When the storage time reaches the timing time, it means that a prompt message can be issued at this time to remind the user to pay attention to the storage time of the food in the food storage device.

[0069] The specific content of the prompt information can be determined according to actual needs. In this embodiment, the prompt information corresponds to the timing duration and the storage location, and the prompt information may include the timing duration or other information determined according to the timing duration, and the prompt information also includes the storage location of the food in the food storage device or other information obtained according to the storage location.

[0070] For example, when the timer is two hours and the user touches the refrigeration reminder button, the controller obtains that the food is stored in the refrigerator. When the food is stored in the refrigerator for two hours, the two-hour timer of the controller ends, and a reminder message is issued by playing a special music "Refrigeration timer has ended".

[0071] Therefore, the user can understand the storage time or timing time of the food according to the prompt information, which is convenient for monitoring the storage status of the food. The user can also understand the storage location of the food according to the prompt information. When the food needs to be taken out, the position of the food can be quickly located in the food storage device, which is convenient for accurately and quickly taking out the food.

[0072] In this embodiment, after the food is placed in the food storage device, the timing duration is obtained, and the storage position of the food in the food storage device is obtained. When the storage time of the food in the food storage device reaches the timing duration, a corresponding prompt message is issued based on the timing duration and the storage position. Thus, by monitoring the storage time and storage position of the food in the food storage device, prompt information is issued in time after the storage time reaches the timing duration, reminding the user that the storage time of the food needs to be paid attention to, and reminding the user of the storage position of the food, so that the user can take out the food from the food storage device in time, reduce the spoilage of the food due to long-term storage, and is conducive to improving the quality of the food and the reliability of the use of the food storage device.

[0073] In an exemplary embodiment, Figure 2 As shown, step 104 includes step 202 and step 204 .

[0074] Step 202, obtaining a save location reminder instruction.

[0075] The storage location reminder instruction carries the food storage location. For example, when the storage location reminder instruction is a refrigeration reminder instruction, the food storage location in the food storage device is a refrigerator. When the storage location reminder instruction is a freezing reminder instruction, the food storage location in the food storage device is a freezer.

[0076] The method of obtaining the save location reminder instruction is not unique. For example, the user can send the save location reminder instruction through the interactive device. The interactive device is connected to the controller and can send the received save location reminder instruction to the controller so that the controller obtains the save location reminder instruction.

[0077] Step 204: If no different storage location reminder instruction is received within the preset waiting time, the storage location of the food in the food storage device is determined according to the current storage location reminder instruction.

[0078] The value of the preset waiting time is not limited and can be set according to actual needs, for example, it can be 3 seconds.

[0079] After receiving the storage location reminder instruction, the controller will wait for a preset waiting time. If the controller does not receive other different storage location reminder instructions within the preset waiting time, the controller determines the storage location of the food in the food storage device according to the storage location reminder instruction currently received.

[0080] Exemplarily, taking the interactive device as a button and the preset waiting time as 3 seconds, when the user touches the refrigeration reminder button and does not switch to the freezing reminder button within three seconds, the controller determines that the storage location of the food is the refrigerator according to the storage location reminder instruction sent by the refrigeration reminder button.

[0081] In this embodiment, after obtaining the storage location reminder instruction, if no different storage location reminder instruction is received within the preset waiting time, the storage location of the food in the food storage device is determined according to the current storage location reminder instruction. Thus, based on the storage location reminder instruction, the storage location of the food can be determined in combination with the user's instruction, thereby improving the accuracy of the determined storage location. In addition, in the process of determining the storage location, a preset waiting time is set, which can effectively reduce the adverse effects of misoperation on the determination of the storage location.

[0082] In an exemplary embodiment, Figure 3 As shown, the method for determining the timing duration may include step 302 and step 304 .

[0083] Step 302: Receive a duration setting instruction.

[0084] The duration setting instruction carries the timing duration, which is used to set the timing duration.

[0085] The method of obtaining the duration setting instruction is not unique. For example, the user can send the duration setting instruction through the interactive device. The interactive device is connected to the controller and can send the received duration setting instruction to the controller so that the controller obtains the duration setting instruction.

[0086] Step 304, determining the timing duration according to the duration setting instruction.

[0087] Users can set the timing duration according to their needs. Correspondingly, the types of timing durations are not unique, and the controller can determine different timing durations. For example, users can set the duration they want to be reminded of as the timing duration according to their personalized needs. For example, if they want to be reminded every two hours, the user can send a duration setting instruction representing two hours, and the controller can determine that the timing duration is two hours based on the duration setting instruction. Alternatively, users can also set the timing duration according to the shelf life of the food. For example, if the shelf life of the food is two, the user can send a duration setting instruction representing two days, and the controller can determine that the timing duration is two days based on the duration setting instruction.

[0088] In this embodiment, receiving a duration setting instruction and determining the timing duration according to the duration setting instruction can make the determined timing duration better meet the user's needs, so that the subsequent prompt information issued based on the timing duration can also better meet the user's needs.

[0089] In an exemplary embodiment, Figure 4 As shown, the food preservation control method also includes step 402 and step 404.

[0090] Step 402: Receive a voice setting instruction.

[0091] The voice setting instruction carries voice prompt information, which is used to set the voice of the prompt.

[0092] The method of obtaining the voice setting instruction is not unique. For example, the user's voice can be recognized by a voice recognition device, and the voice setting instruction can be received by recognizing the user's voice. The voice recognition device is connected to the controller, and the received voice setting instruction can be sent to the controller, so that the controller obtains the voice setting instruction. In an extensible manner, the user's voice can also be recognized by the voice recognition device, so that the controller can obtain other information such as the timing duration and / or the storage location.

[0093] Step 404: Send out a prompt message according to the voice prompt message carried in the voice setting instruction.

[0094] The controller parses the received voice setting instruction, and after obtaining the voice prompt information, when sending the prompt information, the prompt information can be sent according to the voice prompt information, so that the form of the prompt information is richer and the prompt effect is better.

[0095] For example, when a user puts a cake into the refrigerator compartment and says "XXX reminds you to eat cake", and sets the reminder time to 3 hours, the controller recognizes the voice setting instruction as "XXX reminds you to eat cake" and the timer time is 3 hours. The controller then starts timing, and after three hours, the controller determines that the time is up, and controls the buzzer to issue a voice prompt message "XXX reminds you to eat cake".

[0096] In this embodiment, a voice setting instruction is received, and a prompt message is issued according to the voice prompt information carried in the voice setting instruction. By setting the prompt message in this way, the buzzer reminder words are no longer fixed, but can be changed with voice recognition. Compared with only a few default reminder voices, the prompt voice can be made more intelligent and personalized.

[0097] In an exemplary embodiment, the food preservation control method further comprises the step of obtaining food information of the food placed in the food preservation device. In step 106, the step of issuing corresponding prompt information based on the timing duration and the preservation location comprises the step of issuing corresponding prompt information based on the timing duration, the preservation location and the food information.

[0098] Food information is information related to food, and may include, for example, the name, quantity, quality, shape, etc. of the food.

[0099] There is not only one way to obtain food information of food placed in the food preservation device. For example, the food information of the food placed in the food preservation device can be detected by a food detection device, and the food information can be sent to a controller, and the food detection device is connected to the controller. The food detection device can obtain food information by detecting the quality, shape, etc. of the food. The food detection device can be an image acquisition device, etc., which is not limited here. Alternatively, the food information of the food placed in the food preservation device can be obtained by parsing the received user instructions or recognizing the received user voice.

[0100] The step of issuing corresponding prompt information based on the timing duration and the storage location may include the step of issuing corresponding prompt information based on the timing duration, the storage location and the food information.

[0101] Among them, the prompt information includes not only the timing duration or other information determined according to the timing duration, the storage location of the food in the food storage device or other information obtained according to the storage location, but also the food information. Therefore, the user can understand the storage location, timing duration and food information of the food according to the prompt information, which is convenient for comprehensive and targeted monitoring of the storage status of the food, so that timely measures can be taken before the food spoils.

[0102] In this embodiment, after obtaining the food information of the food placed in the food preservation device, corresponding prompt information is issued based on the timing duration, the preservation location and the food information, so as to facilitate comprehensive and targeted monitoring of the preservation status of the food, so that timely measures can be taken before the food deteriorates, which is conducive to improving the quality of the food.

[0103] In an exemplary embodiment, the food preservation control method further includes the steps of obtaining the amount of food put into the food preservation device and issuing a prompt message corresponding to the amount of food.

[0104] The method of obtaining the amount of food put into the food preservation device is not unique. For example, the amount of food put into the food preservation device can be detected by a food detection device, and the amount of food can be sent to a controller, and the food detection device is connected to the controller. The food detection device can be an image acquisition device, etc., which is not limited here. Alternatively, the amount of food put into the food preservation device can be obtained by parsing the received user instructions or recognizing the received user voice.

[0105] The controller issues prompt information corresponding to the amount of food, for example, the prompt information of the current amount of food is issued. When the amount of food increases or decreases, the controller will update the stored amount of food, and may also issue prompt information corresponding to the increased or decreased amount of food. Thus, the user can timely understand the amount of food stored in the food storage device through the prompt information, so as to better manage the stored food.

[0106] In this embodiment, the amount of food put into the food storage device is obtained, and prompt information corresponding to the amount of food is issued. Thus, the user can timely understand the amount of food stored in the food storage device through the prompt information, so as to better manage the stored food.

[0107] In an exemplary embodiment, Figure 5 As shown, after step 104 and before step 106, the food preservation control method further includes step 505: issuing a reminder function start prompt message.

[0108] Among them, the reminder function startup prompt information is used to remind the user that the reminder function has been turned on at this time. Under the reminder function, the corresponding prompt information will be issued later.

[0109] For example, when the timer is two hours and the user touches the refrigeration reminder key and does not switch to the freezing reminder key within three seconds, the controller controls the interactive device to issue a reminder message indicating that the refrigeration reminder function has been enabled and a reminder will be issued in two hours. When the food is stored in the refrigerator for two hours, the controller's two-hour timer ends and a reminder message is issued by playing a special music message indicating that the refrigeration timer has ended.

[0110] In this embodiment, the reminder function activation prompt information is sent to remind the user that the reminder function has been turned on, so that the user can understand the working status of the food preservation device.

[0111] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0112] Based on the same inventive concept, the embodiment of the present application also provides a food preservation control device for implementing the above-mentioned food preservation control method. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above-mentioned method, so the specific limitations in one or more food preservation control device embodiments provided below can refer to the limitations of the food preservation control method above, and will not be repeated here.

[0113] In an exemplary embodiment, Figure 6 As shown, a food preservation control device is provided, comprising:

[0114] The duration acquisition module 602 is used to acquire the timing duration after the food is put into the food preservation device.

[0115] The location acquisition module 604 is used to acquire the storage location of the food in the food storage device.

[0116] The prompt module 606 is used to send corresponding prompt information based on the timing time and the storage location when the storage time of the food in the food storage device reaches the timing time.

[0117] In an exemplary embodiment, the location acquisition module is also used to obtain a storage location reminder instruction; if no different storage location reminder instruction is received within a preset waiting time, the storage location of the food in the food storage device is determined according to the current storage location reminder instruction.

[0118] In an exemplary embodiment, the duration acquisition module is further used to receive a duration setting instruction; and determine the timing duration according to the duration setting instruction.

[0119] In an exemplary embodiment, the prompt module is further configured to receive a voice setting instruction; and issue a prompt message according to the voice prompt message carried in the voice setting instruction.

[0121] In an exemplary embodiment, the prompt module is also used to obtain the amount of food put into the food preservation device; and issue a prompt message corresponding to the amount of food.

[0122] In an exemplary embodiment, the prompt module is also used to issue a reminder function start prompt message after the position acquisition module obtains the storage position of the food in the food storage device, and before the prompt module issues a corresponding prompt message based on the timing time and the storage position when the storage time of the food in the food storage device reaches the timing time.

[0123] Each module in the above-mentioned food preservation control device can be implemented in whole or in part by software, hardware and a combination thereof. Each module can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute the operations corresponding to each module above.

[0124] An embodiment of the present application also provides a food preservation control device, including an interactive device and a controller, wherein the interactive device is connected to the controller, and the controller is used to perform food preservation control according to the method of any of the above embodiments.

[0125] The structure of the interactive device is not unique. In an exemplary embodiment, the interactive device includes an instruction receiving device and a prompting device, both of which are connected to the controller. The instruction receiving device can be used to receive user instructions and send them to the controller, and the prompting device can send corresponding prompt information under the control of the controller. The interactive device can better achieve interaction with the user.

[0126] The structure of the instruction receiving device is not limited, for example, it can include one or more of a touch screen, a button, and a voice recognition device, which can be selected according to actual needs. The structure of the prompting device is also not limited, for example, it can include one or more of a display device and a voice prompting device, which can be selected according to actual needs.

[0127] In an exemplary embodiment, the prompt device includes a display device and a voice prompt device, and both the display device and the voice prompt device are connected to the controller. The display device can issue corresponding prompt information by displaying relevant content, and the prompt effect is intuitive. The voice prompt device can issue corresponding prompt information by playing voice, and the user can easily receive the voice prompt information.

[0128] In an exemplary embodiment, a display device includes a display module and a display circuit chip peripheral circuit, wherein the display circuit chip peripheral circuit connects a controller and the display module.

[0129] The display module is used for display, and the peripheral circuit of the display circuit chip connects the controller and the display module, and is used to cooperate with the display module under the control of the controller so that the display module can display correct information.

[0130] The display module can include different COM (Communication Port) channels, and different COM channels control different LED lights on the display module to light up. For example, different LED lights can alternately display "freeze" or "refrigerate", and the reminder of the end of freezing or refrigeration can be changed by touching the key.

[0143] In an exemplary embodiment, the food preservation control device further comprises a food detection device connected to the controller. The food detection device is used to detect food information of food put into the food preservation device and send the food information to the controller.

The food detection device may obtain the food information by detecting the quality, shape, etc. of the food, and send the food information to the controller.

[0145] In this embodiment, the food preservation control device further includes a food detection device, which is connected to the controller. The food detection device is used to detect food information of food placed in the food preservation device and send the food information to the controller. By detecting food information by the food detection device, the function of the food preservation device can be enriched and the working performance can be improved.

[0146] An embodiment of the present application also provides a food preservation system, including a food preservation device and a food preservation control device as in any of the above embodiments.

[0147] In order to better understand the above embodiment, a detailed explanation is given below in conjunction with a specific embodiment. In one embodiment, taking the food preservation device as a refrigerator as an example, the food preservation control device includes an interactive device and a controller, and the interactive device includes an instruction receiving device and a prompting device. The prompting device includes a display device and a voice prompting device. The display device includes a display module and a display circuit chip peripheral circuit. The voice prompting device includes a buzzer and a buzzer peripheral circuit. The controller includes a main chip and a main chip peripheral circuit. Taking the food as cola as an example, the food preservation control method may include:

[0148] Step 1: Start the refrigerator timer reminder function. The function is to put in room temperature cola, and it will send a reminder to take out the cola after the required time.

[0149] Step 2: The user puts the cola into a refrigerator or freezer, so that the user can get ice cola after the timer is up.

[0150] Step 3: Take out the ice cola after the timer ends.

[0151] The structure of the peripheral circuit of the display circuit chip is as follows Figure 7 As shown, it includes transistor Q1, transistor Q2, transistor Q3 and transistor Q4. The structure of the buzzer peripheral circuit is as follows Figure 8 As shown, it includes a voltage divider resistor R5, a current limiting resistor R6 and a switch transistor Q5. The structure of the main chip peripheral circuit is as follows Fig. 9 As shown, it includes filter capacitor C1, filter capacitor C2, voltage divider resistor R7, voltage divider resistor R8 and voltage divider resistor R9. When com1 channel needs to be always on, the main chip output signal flows through R1, turns on switch tube Q1, and makes VDC flow to com1. The spring adopts touch control logic (depending on program writing), and the three spring touch buttons are a timing function start button, a freezing reminder button, and a refrigeration reminder button. The music buzzer can prompt different music buzzes according to different selections of touch buttons.

[0152] The working process of the food preservation control device includes: when the timing function start key is touched, it is considered that the timing reminder function is needed, and the freezing reminder or the refrigeration reminder can be selected at this time. When the refrigeration reminder key is touched and it is not switched to the freezing reminder key within three seconds, the main chip controls the emission of pwm wave 1 to drive the transistor Q5 in the peripheral circuit of the buzzer to turn on, the buzzer is energized, and a special music "The refrigeration reminder function has been enabled, and a reminder will be given in two hours" is emitted. After the two-hour timing ends, the buzzer emits a special music "The refrigeration timing has ended". When the freezing reminder key is touched and it is not switched to the freezing reminder key within three seconds, the main chip controls the emission of pwm wave 2 to drive the transistor Q5 in the peripheral circuit of the buzzer to turn on, the buzzer is energized, and a special music "The freezing reminder function has been enabled, and a reminder will be given in half an hour" is emitted. After the half-hour timing ends, a special music "The freezing timing has ended" is emitted. When the ending music is emitted, the timing reminder function is automatically turned off. If the timing needs to continue, the timing key needs to be touched again.

[0153] In addition, the food preservation control device can also add a timer time change function, and the timer duration can be set at will. It can also add voice recognition, and special music can be set by itself, so that the special buzzer can be directly recognized and used. It can also add a shelf life timer countdown system. When setting the timer, you can enter a shelf life duration and issue a reminder every "a period of time". Sensors can also be added to sense the quality and shape of the items put in, and name the items put in. For example, the logic process can be set to "put xx items in the refrigerator, remind me to take them out after xx time, if not taken out, remind me every xx time until the item is taken out." It can also be set to "xx items have been put in the refrigerator for xx time. It is a short-shelf food. There is still xx time before the expiration date. It is recommended to take it out as soon as possible." In addition, a warehouse system can be added to view the number of items placed in the refrigerator, the shelf life, etc. When putting an item in, input the voice "I put an item of xx in the refrigerator", and the refrigerator will automatically increase the number of warehouses after recognition. When it is taken out, it will automatically sense that the item has been taken out, and the number of warehouses will automatically decrease by one.

[0154] In the above embodiment, by monitoring the storage time and storage location of food in the food storage device, a prompt message is promptly issued after the storage time reaches the preset time, reminding the user that the storage time of the food needs to be paid attention to, and reminding the user of the storage location of the food, so that the user can take out the food from the food storage device in time, reducing the spoilage of food due to long-term storage, which is beneficial to improving the quality of food and also improving the reliability of the use of the food storage device.
