[0032] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0033] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0034] Unless otherwise stated, the term "plurality" means two or more.

[0035] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0036] The term "and / or" is a description of the association relationship between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or, A and B.

[0037] The term "correspondence" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0038] Combination Figures 1 to 3 The refrigerator includes a multi-layer shelf 30, a multi-section lighting device 10 and a plurality of light intensity sensors 20. The multi-layer shelf is arranged in the inner cavity of the refrigerator for storing goods. A multi-section lighting device is arranged on the side wall corresponding to each layer of the shelf, and the multi-section lighting device is arranged along the side wall from the door side to the inner cavity in sequence. A light intensity sensor corresponding to the multi-section lighting device is arranged on the other side wall opposite to the side wall. The number of segments of the lighting device on each layer of the shelf matches the number of light intensity sensors. In this way, each light intensity sensor detects the light intensity of the corresponding segment of the lighting device. The multi-section lighting device divides each layer of the shelf into multiple areas, such as from the door side to the rear wall into the front section, the middle section, and the rear section, or multiple areas such as the front section and the rear section. The lighting device includes a spotlight or an LED (Light-Emitting Diode) lamp, etc.

[0039] It is understandable that when the lighting device is turned on, whether goods are stored on each shelf and how much goods are stored will affect the light to varying degrees. This causes obvious differences in the light intensity data detected by the light intensity sensor. Therefore, the goods situation in each section of the shelf can be determined by detecting the light intensity of the shelf. The switch state of the lighting device is then controlled based on the goods situation. For example, when there are goods in a certain area, the lighting device corresponding to the area is controlled to remain on, and the lighting device corresponding to the area where there are no goods is controlled to be turned off. In this way, the switch state of multiple sections of lighting devices can be accurately controlled so that the lighting device accurately illuminates the area with goods. This helps to display the goods and facilitates people to buy.

[0040] Optionally, the lighting device 10 has two or three sections. Here, there should not be too many lighting devices. Too many lighting devices will not only increase costs, but also cause energy waste. Specifically, the number of sections of the lighting device can be determined based on the depth of the refrigerator. If the depth of the refrigerator is shallow, a two-section lighting device can be selected. If the depth of the refrigerator is deep, a three-section lighting device can be selected. The depth of the refrigerator refers to the distance from the refrigerator door to the rear wall. In addition, the lighting device and the light sensor are arranged in the middle and lower position of each shelf area. In this way, it can be avoided that some goods are too low to block the light, which affects the judgment of the goods information.

[0041] Optionally, a weighing sensor 40 is provided on each shelf 30 .

[0042] When the refrigerator is set up in an office building or a shopping mall, the refrigerator does not need 24-hour lighting. The lighting device of the refrigerator can be turned on based on the working hours of the place. When the lighting device is not turned on, the light intensity sensor cannot determine the condition of the goods on the shelf. However, for suppliers, it is necessary to understand the condition of the goods in the refrigerator regularly. Such as after the end of business hours or before business hours or at a fixed time every day, so as to replenish the goods in the refrigerator in time. Therefore, in the embodiment of the present disclosure, a weighing sensor is set on the shelf to detect the goods information through the weighing sensor when the light sensor cannot detect the goods information.

[0043] Optionally, the weighing sensor 40 of each shelf layer includes a first weighing sensor 41 and a second weighing sensor 42, which are respectively arranged at the front and rear ends of each shelf layer.

[0044] Here, the cargo situation of each shelf can be determined by the weighing sensors at the front and rear ends of each shelf. For example, when the value of the first weighing sensor is much greater than the value of the second weighing sensor, it indicates that there are more cargoes at the front end of the shelf. At this time, the lighting device at the rear side can be controlled to be turned off, and the lighting device at the front side can be kept on. When the value of the first weighing sensor is much less than the value of the second weighing sensor, it indicates that there are more cargoes at the rear end of the shelf. At this time, the lighting device at the front side can be controlled to be turned off, and the lighting device at the rear side can be kept on.

[0045] Optionally, a plurality of air outlets are provided on the rear side wall corresponding to each shelf layer.

[0046] Here, each air outlet can independently control the switch state. Based on the cargo information of each shelf, the state of the air outlet is controlled. It can be understood that when the amount of cargo on each shelf is large, all the air outlets can be controlled to be in an open state. When the amount of cargo on each shelf is small, only some of the air outlets can be controlled to be in an open state. Specifically, the amount of cargo on each shelf is positively correlated with the number of air outlets in an open state.

[0047] Combination Figure 4 As shown, the embodiment of the present disclosure provides a method for monitoring refrigerated goods, comprising:

[0048] S101, the processor obtains the ambient light intensity information of the refrigerator.

[0049] S102, when the ambient light intensity information indicates that the ambient light intensity meets the set conditions, the processor obtains light intensity data of multiple light intensity sensors corresponding to each shelf layer.

[0050] S103, the processor determines the cargo information of each shelf layer according to the light intensity data.

[0051] S104, the processor controls the switch state of the corresponding lighting device according to the cargo information.

[0052] Here, the light intensity information of the environment where the refrigerator is located is obtained, on the one hand, to determine whether the lighting device of the refrigerator is in working state, and on the other hand, to determine whether there is interference in the external environment, which affects the detection accuracy of the light intensity sensor of the refrigerator. When the ambient light intensity meets the set conditions, the light intensity data of each shelf is detected by the light intensity sensor. Among them, the initial state of the lighting device of the refrigerator is turned on.

[0053] Furthermore, based on the light intensity data, the cargo information of each shelf layer is determined. Among them, the cargo information mainly includes the amount of cargo. Specifically, the sizes of multiple light intensity data of each shelf layer are compared. The smaller the light intensity data value, the more cargo there is in this area. The closer the light intensity data is to the maximum light intensity of each section of the lighting device, the more cargo there is in this area. In this way, the amount of cargo on each shelf layer can be determined more accurately. Then, based on the amount of cargo, the on / off state of the lighting device corresponding to the cargo area is controlled. For example, the lighting device corresponding to the area with less cargo is controlled to be turned off, and the lighting device corresponding to the area with more cargo is kept on.

[0054] Using the method for monitoring goods in a refrigerator provided by an embodiment of the present disclosure, when the ambient light intensity information meets the set conditions, a light intensity sensor is used to detect the light intensity data of the lighting device on each shelf. Then, based on the light intensity data, the cargo information of each shelf is determined. Here, the lighting device and the light intensity sensor are arranged on opposite sides. When goods are stored on the shelf, the goods will block the light of the lighting device. Therefore, the condition of the goods on the shelf can be determined by the light intensity data. And the lighting device is multi-segment, and the condition of the goods in multiple sections of the shelf can be determined. Therefore, the switching state of the multi-segment lighting device can be accurately controlled, so that the lighting device accurately illuminates the area with goods.

[0055] Optionally, the processor determines whether the ambient light intensity meets the set condition in the following manner:

[0056] The ambient light intensity is less than the first ambient light intensity and greater than the second ambient light intensity;

[0057] The second ambient light intensity refers to the lowest ambient light intensity that satisfies the lighting condition, and the first ambient light intensity refers to the ambient light intensity that has the least impact on the light intensity sensor.

[0058] Here, as described above, the second ambient light intensity refers to the lowest light intensity in the environment when the refrigerator is working normally, and the normal working of the refrigerator means that the lighting device of the refrigerator is turned on. The first ambient light intensity refers to the ambient light intensity that has the least impact on the detection of the light intensity sensor. In this way, the light intensity sensor is used for detection under the appropriate ambient light intensity environment.

[0059] Optionally, in step S103, the processor determines the cargo information of each shelf layer according to the light intensity data, including:

[0060] In the case of L1>L2+L3, the processor determines that the front section of the corresponding shelf is sold out.

[0061] In the case where L1+L2>a*L3, the processor determines that the goods in the front middle section of the corresponding shelf are sold out.

[0062] When L1+L2+L3≥3Lmax, the processor determines that all the goods on the corresponding shelf are sold out.

[0063] Among them, L1 is the light intensity data of the first light intensity sensor, L2 is the light intensity data of the second light intensity sensor, L3 is the light intensity data of the third light intensity sensor, Lmax is the maximum light intensity of each lighting device, and a is a constant.

[0064] In the disclosed embodiment, cargo information is determined based on the situation where three sections of lighting devices are set on each shelf. The positions of the three light intensity sensors are sequentially arranged along the depth direction of the refrigerator, with the first light intensity sensor close to the door body and the third light intensity sensor close to the rear wall. It is understandable that the lighting device on each shelf has a certain interference with the detection results of the light intensity sensor, such as the front section lighting device interfering with the detection value of the middle section light intensity sensor. Therefore, judging the cargo situation in each cargo area of ​​the shelf based on the logical relationship between the three light intensity data helps to reduce the impact of interference on the accuracy of judgment.

[0065] Specifically, when L1>L2+L3, it indicates that the light intensity of the front section area is greater than the sum of the light intensity of the middle and rear sections. Because the light intensity of the front section area is also affected by the environment (such as high ambient brightness), the light intensity data of the first light intensity sensor will be increased. Therefore, the light intensity data of the first light intensity sensor and the sum of the light intensity data of the second and third light intensity sensors are compared. If it is greater than, it means that the light intensity of the front section is larger, indicating that there is basically no goods in the front section (that is, the goods in the front section of the shelf are sold out). Similarly, if the sum of the light intensity data of the first and second light intensity sensors is greater than several times the light intensity data of the third sensor; it indicates that the goods in the front and middle sections are sold out. When all the goods on a shelf on a certain layer are sold out, the sum of the light intensities of the first, second, and third light intensity sensors is basically equal to three times the maximum light intensity of the lighting device. In some scenarios, the light of the external environment may increase the detection values ​​of the first and second light sensors, so here when L1+L2+L3≥3Lmax, it is determined that all the goods on the corresponding shelf are sold out. Among them, a≥4, the deeper the depth of the refrigerator, the larger the value of a.

[0066] Optionally, in step S103, the processor determines the cargo information of each shelf layer according to the light intensity data, including:

[0067] In the case where L1>b*L2, the processor determines that the front section of the corresponding shelf is sold out.

[0068] In the case where L1+L2≥2Lmax, the processor determines that the goods on the corresponding shelf are sold out.

[0069] Among them, L1 is the light intensity data of the first light intensity sensor, L2 is the light intensity data of the second light intensity sensor, Lmax is the maximum light intensity of each lighting device, and b is a constant.

[0070] In the embodiment of the present disclosure, the cargo information is determined for the case where two sections of lighting devices are set on each shelf. Similarly, the light intensity sensor is set along the depth direction of the refrigerator. b≥3, and its value also increases with the increase of the cabinet depth.

[0071] Optionally, in step S103, the processor determines the cargo information of each shelf layer according to the light intensity data, and further includes:

[0072] The processor obtains the light intensity data and the change amount of the historical light intensity data.

[0073] If the change in the first time period is continuously less than the first threshold, the processor determines that the goods on the corresponding shelf are at risk of expiring. 。

[0074] Here, in addition to the quantity of goods mentioned above, the goods information also includes the storage time of the goods. Specifically, the light intensity data is compared with the historical light intensity data to obtain the change in light intensity. Among them, the historical light intensity data refers to the light intensity data of the last time. If the change is continuously less than or lower than the first threshold value within the first time period, it indicates that the goods on the shelf of this layer have basically not been sold within the first time period, that is, the goods on the shelf of this layer have been stored in the refrigerator. In this way, the goods have been stored for too long and there is a risk that they may be close to the shelf life. Among them, the first time period can be set based on the shelf life of the goods. For example, if the shelf life of the goods is 6 months, the first time period can be 3-4 months. The first threshold value can be the impact value of the goods of the minimum sales unit on the light intensity. In addition, the first time period can also be a shorter time period such as one month, which means that the goods on the shelf are not selling well. The salesperson can consider replacing the goods, which can also reduce losses. It should be noted that the change refers to the change of multiple sensors on the shelf of this layer. That is, multiple changes are continuously less than the first threshold.

[0075] Combination Figure 5 As shown, the embodiment of the present disclosure provides another method for monitoring refrigerated cargo, comprising:

[0076] S101, the processor obtains the ambient light intensity information of the refrigerator.

[0077] S102, when the ambient light intensity information indicates that the ambient light intensity meets the set conditions, the processor obtains light intensity data of multiple light intensity sensors corresponding to each shelf layer.

[0078] S103, the processor determines the cargo information of each shelf layer according to the light intensity data.

[0079] S205, when the ambient light intensity information indicates that the ambient light intensity does not meet the set conditions, the processor obtains the current weighing data and the previous historical data corresponding to each shelf.

[0080] S206: The processor determines the cargo information of each shelf layer according to the current weighing data and the previous historical data.

[0081] S104, the processor controls the switch state of the corresponding lighting device according to the cargo information.

[0082] As mentioned above, in some scenarios (such as when the lighting device of the refrigerator is turned off or there is strong light in the external environment), the light intensity sensor cannot accurately obtain light intensity data that can characterize the information of the goods. In this case, the weighing sensor can be used to determine the goods information of each shelf. Specifically, the current weighing data of each shelf is obtained, that is, the last historical data. Because there are two weighing sensors on each shelf, the current weighing data and the last historical data both include two data. It can be understood that by comparing the current two weighing data, it can only be determined in theory whether there are goods in the front section area or the rear section area; it cannot be determined whether the goods on this shelf are sold out. Therefore, here, it can be determined whether the goods in the front section or the rear section area are sold out by the size relationship of the current two weighing data. Then, based on the current weighing data and the last historical data, it is determined whether the goods on each shelf are sold out. As an example, when the value of the first weighing sensor is much greater than that of the second weighing sensor, it indicates that there is basically no goods in the rear area of ​​the shelf. When the value of the first weighing sensor is much smaller than that of the second weighing sensor, it indicates that there is basically no goods at the front end of the shelf. When the sum of the current weighing sensor values ​​is much smaller than the sum of the historical values, it is determined that there is no stock on the shelf.

[0083] Optionally, the goods information of each shelf is determined according to the current weighing data and the previous historical data, including: in the case of G2>c*G1, determining that the front section of the goods on the corresponding shelf are sold out;

[0084] In the case where (G1+G2)>(G1'+G2') / d, it is determined that the goods on the corresponding shelf are sold out;

[0085] Among them, G1 is the current weighing data of the first weighing sensor, G2 is the current weighing data of the second weighing sensor, G1' and G2' are the previous historical data, and c and d are constants.

[0086] In the disclosed embodiment, the goods in the rear section of the refrigerator will not be pushed into the front section after the goods in the front section are sold out. Therefore, here it is only necessary to determine whether the goods in the front section are sold out, or whether a certain shelf is sold out (if the front section is sold out, only the lighting device in the rear section needs to be turned on; if the goods on a certain shelf are sold out, all the lighting devices on that shelf need to be turned off). Specifically, when G2>c*G1, it indicates that the goods in the front section are sold out. Where c≥2. When (G1+G2)>(G1'+G2') / d, it indicates that the goods on that shelf are sold out. Where d≥4.

[0087] Combination Figure 6 As shown, the embodiment of the present disclosure provides another method for monitoring refrigerated cargo, comprising:

[0088] S101, the processor obtains the ambient light intensity information of the refrigerator.

[0089] S102, when the ambient light intensity information indicates that the ambient light intensity meets the set conditions, the processor obtains light intensity data of multiple light intensity sensors corresponding to each shelf layer.

[0090] S103, the processor determines the cargo information of each shelf layer according to the light intensity data.

[0091] S205, when the ambient light intensity information indicates that the ambient light intensity does not meet the set conditions, the processor obtains the current weighing data and the previous historical data corresponding to each shelf;

[0092] S206: The processor determines the cargo information of each shelf layer according to the current weighing data and the previous historical data.

[0093] S104, the processor controls the switch state of the corresponding lighting device according to the cargo information.

[0094] S307: The processor outputs corresponding prompt information according to the cargo information.

[0095] Here, according to the goods information, not only can the on / off state of the lighting device be accurately controlled, but also information can be provided to the salesperson so that the goods can be replenished in time. Specifically, after the goods in a certain area are sold out, the first replenishment notice is output. After the goods in multiple areas are sold out, the second replenishment notice is output. Alternatively, when the goods on a certain shelf are at risk of expiring, the first reminder notice is output. Among them, the first replenishment notice is that the goods are about to sell out; the second replenishment notice is that the goods are sold out; the first reminder notice is that the goods are not selling well and please consider replacing the goods or the goods are not selling well and are about to expire.
