[0022] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the present application, many technical details are proposed in order to enable the reader to better understand the present application. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present application can also be implemented. The division of the following embodiments is for the convenience of description, and the specific implementation of the present application should not be construed as any limitation, and the various embodiments can be combined and referenced with each other under the premise of no contradiction.
[0023] As people's living standards improve, refrigerators have entered thousands of households, providing a suitable environment for people to store food. Eggs are a common ingredient for people to make food because of their high nutritional value and low price. Eggs are suitable for storage in a refrigerated environment of 2℃ to 4℃. This temperature range can effectively inhibit the growth of bacteria and keep the eggs fresh. Therefore, for most families, the refrigerator's refrigerator is the preferred place to store eggs. But even under refrigerated conditions, too long a storage period will cause the eggs to deteriorate and become inedible.
[0024] Existing technical means can only predict whether eggs are fresh or whether the eggs are likely to deteriorate based on the number of days they have been stored in the refrigerator. However, the eggs we buy from the market have been stored for a certain period of time, which we cannot know, and the shelf life of eggs in different storage environments is also uncertain. Therefore, existing technology cannot accurately detect whether each egg is still edible.
[0025] In order to solve the above technical problems, the present invention proposes a method for determining the freshness of eggs. The implementation details of the method for determining the bandwidth of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.
[0026] Embodiment 1:
[0027] like Figure 1 As shown, the present application provides a method for determining the freshness of eggs, and the method is applied to electronic production equipment, and the electronic production equipment can be a server, a mobile terminal, a computer, a cloud platform, a refrigerator, etc. The function implemented by the production equipment data processing provided in the embodiment of the present application can be implemented by calling the program code by the processor of the electronic production equipment, wherein the program code can be stored in a computer storage medium. The method for determining the freshness of eggs includes:
[0028] Step S1: Monitor the current state of the refrigerator.
[0029] Step S2: When the current state meets the preset conditions, each egg storage slot in the egg storage box is irradiated with ultrasound.
[0030] Since the internal structures of fresh eggs and spoiled eggs are different, the internal structure of fresh eggs is compact, so the transmittance to ultrasound is lower, while the internal structure of spoiled eggs is loose, so the transmittance to ultrasound is higher. Therefore, in this application, the freshness of eggs can be determined by analyzing the results after ultrasound of the same power passes through different eggs.
[0031] In order to accurately detect the freshness of each egg, it is necessary to lay out each egg separately. Therefore, an egg storage box is used to store the eggs. In order to lay out the eggs separately, a plurality of egg storage slots are provided in the egg storage box. Each egg storage slot can be used to accommodate eggs. Therefore, when the preset conditions are met, it is necessary to use ultrasonic wave to irradiate the egg storage slot to realize the detection of the freshness of the eggs.
[0032] Although the application can detect the freshness of eggs, it is not necessary to detect the freshness of eggs all the time. Most of the time, users will not eat eggs, and constantly detecting the freshness of eggs will cause certain damage to the eggs, and it will also waste a lot of resources. Therefore, in the application, the freshness of eggs will be detected only when the preset conditions are met.
[0033] Therefore, there are three preset conditions in this application, and as long as any one of the conditions is met, the egg freshness detection will be started. Therefore, in some embodiments, step S2 "when the current state meets the preset conditions, use ultrasound to irradiate each egg storage slot in the egg storage box" includes:
[0034] Step S21: When the refrigerator door is opened, each egg storage slot in the egg storage box is irradiated with ultrasonic waves.
[0035] Step S22: When the interval time is greater than or equal to the preset time, each egg storage slot in the egg storage box is irradiated with ultrasonic waves.
[0036] Step S23: When the egg storage box is closed, each egg storage slot in the egg storage box is irradiated with ultrasonic waves.
[0037] Steps S21 to S23 are in parallel relationship. When any condition is met, the egg freshness detection work will be performed. Since the purpose of detecting the freshness of eggs is to let users know which eggs have problems and avoid being eaten by users, and to allow users to dispose of spoiled eggs in time, and when the refrigerator is closed, it is difficult for users to notice the freshness of eggs in the refrigerator, so the opening of the refrigerator door is used as a condition of the preset condition in this application. Because when the refrigerator door is opened, it means that the user may eat eggs, so the freshness of the eggs needs to be detected at this time.
[0038] The egg storage box is a space for storing eggs in the refrigerator. It is inevitable to take and add eggs, which will cause changes in the eggs in the egg storage box. When the egg storage box is closed, it means that the change of the eggs in the egg storage box has been completed. At this time, the freshness of each egg in the egg storage box can be tested again. Therefore, in this application, the closing of the storage box is used as a condition, and the freshness of the newly added eggs in the egg storage box can be detected at this time.
[0039] In addition, it is necessary to regularly check the freshness of the eggs, so the present application also sets a preset time condition. When the interval from the last time the ultrasonic transmittance was obtained is greater than or equal to the preset time, ultrasonic waves are used to irradiate each egg storage slot in the egg storage box.
[0040] Step S3: Obtaining the ultrasonic transmittance of each egg storage tank and a preset first preset transmittance.
[0041] Step S4: determining the freshness of the eggs in each egg storage tank according to the first preset transmittance and the ultrasonic transmittance.
[0042] In some embodiments, step S4 of "determining the freshness of eggs in each egg storage tank according to the first preset transmittance and the ultrasonic transmittance" includes:
[0043] Step S41: When the ultrasonic transmittance is less than the first preset transmittance, it is determined that the eggs in the egg storage tank are fresh eggs.
[0044] In some embodiments, step S4 of "determining the freshness of eggs in each egg storage tank according to the first preset transmittance and the ultrasonic transmittance" includes:
[0045] Step S42: Obtain a second preset transmittance.
[0046] Step S43: When the ultrasonic transmittance is greater than or equal to the first preset transmittance and less than the second preset transmittance, it is determined that the eggs in the egg storage tank are spoiled eggs.
[0047] Step S44: When the ultrasonic transmittance is greater than or equal to the second preset transmittance, it is determined that there are no eggs in the egg storage tank.
[0048] Step S45: The locations of the egg storage tanks with spoiled eggs and the egg storage tanks without eggs are displayed to the user.
[0049] Since eggs of different freshness have different transmittances to ultrasound, the present application presets a first preset transmittance, and the eggs are distinguished as spoiled and fresh by the first preset transmittance and the ultrasound transmittance. However, although the ultrasound transmittance of spoiled eggs is higher than that of fresh eggs, there is still a limit, so the present application also presets a second preset transmittance, and the second preset transmittance is used to distinguish whether there are eggs in the egg storage tank, wherein when there are no eggs in the egg storage tank, the collected transmittance is the transmittance of air, which is close to 1. Therefore, the setting of the second transmittance in the present application can distinguish egg storage tanks with spoiled eggs from egg storage tanks without eggs, and can also notify the user of the distinction result.
[0050] The notification method can be to install LED lights at the bottom of each egg storage tank, and light up lights of different colors according to different judgment results, or send it to the user's mobile terminal device in other ways, so that the user can know the freshness of the eggs in the refrigerator and the remaining eggs in the refrigerator in time, which greatly improves the user's refrigerator experience. In addition, since spoiled eggs can be found in time, the user can clean up the spoiled eggs in time, so that other surrounding eggs will also spoil under the influence of spoiled eggs. The problem that the freshness of eggs cannot be accurately determined in the prior art is solved, and the health and food safety of users are greatly guaranteed.
