Abstract

The present invention discloses a storage device, a bottle identification method and apparatus for use in the storage device, the method comprising obtaining a radio frequency tag signal; when the radio frequency tag signal includes the first tag information, determining that the bottle is outside the storage device; and when the radio frequency tag signal contains only the second tag information, determining that the bottle is inside the storage device. When a wine bottle is full of wine, the first tag information cannot be identified. If it is identified, it indicates that there is no wine or very little wine in the bottle, and the detected wine bottle is further determined to be a wine bottle outside the wine cabinet. In addition, the small amount of electromagnetic waves leaking outside the wine cabinet causes signal attenuation due to the liquid in the wine bottle, so that when only the second tag information is obtained, it can be determined that the bottle is inside the wine cabinet, thereby achieving accurate judgment of whether the wine bottle is inside the wine cabinet.

Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a storage device, and a bottle identification method and device for the storage device. Background Art

[0002] Storage devices with RFID (Radio Frequency Identification) recognition capabilities, such as wine cabinets, may experience misidentification when identifying bottles within the storage device, such as wine bottles. During the implementation of the present invention, the inventors discovered that the causes of this misidentification problem are:

[0003] 1. RF signals attenuate when passing through liquids. The recognition capability is reduced when RF signals pass through the wine in the bottle, so some tags with poor performance may fail to be recognized.

[0004] 2. Based on the above reason 1, if the signal power is increased, although radio frequency identification is mainly used to identify bottles inside the wine cabinet, when some areas cannot be well shielded, radio frequency leakage may occur outside the wine cabinet, causing identification outside the wine cabinet. In addition, the empty bottle body no longer has signal attenuation caused by liquid, making it more likely to be misidentified.

[0005] Therefore, the problem of misidentification cannot be solved well at present. Summary of the Invention

[0006] In order to solve the above-mentioned problem of misidentification of wine cabinets in the prior art, an object of the present invention is to provide a storage device that can accurately identify bottles, and a bottle identification method and device for the storage device.

[0007] To achieve the above-mentioned object of the invention, one embodiment of the present invention provides a bottle identification method for storage equipment, wherein the bottle includes a bottle body, and a first radio frequency tag and a second radio frequency tag attached to the bottle body and corresponding to the bottle body, wherein the first radio frequency tag corresponds to first tag information, and the second radio frequency tag corresponds to second tag information. When the bottle is full of liquid, the first radio frequency tag cannot be radio frequency identified, but the second radio frequency tag can be radio frequency identified. The method comprises the steps of:

[0008] Obtain radio frequency tag signals;

[0009] When the radio frequency tag signal includes the first tag information, determining that the bottle is a bottle outside the storage device;

[0014] As a further improvement of the present invention, the first tag information includes specific information;

[0015] Also includes the steps:

[0016] When the radio frequency tag signal includes the specific information, it is determined that the bottle is a bottle outside the storage device.

[0017] As a further improvement of the present invention, the following steps are also included:

[0018] When it is determined that the bottle body is a bottle body inside the storage device, the second label information is recorded.

[0019] As a further improvement of the present invention, the step of obtaining the radio frequency tag signal includes:

[0020] When it is detected that the door of the storage device is opened and then closed again, the radio frequency tag signal is acquired.

[0021] As a further improvement of the present invention, the first radio frequency tag is attached to the bottom of the bottle body.

[0022] To achieve one of the above-mentioned objectives, an embodiment of the present invention provides a bottle identification device for storage equipment, wherein the bottle includes a bottle body, and a first radio frequency tag and a second radio frequency tag attached to the bottle body and corresponding to the bottle body, wherein the first radio frequency tag corresponds to first tag information, and the second radio frequency tag corresponds to second tag information.

[0023] An acquisition module, used to acquire radio frequency tag signals;

[0024] a first determining module, configured to determine that the bottle is a bottle outside the storage device when the radio frequency tag signal includes the first tag information;

[0025] The second judgment module is configured to judge that the bottle is a bottle inside the storage device when the radio frequency tag signal contains only the second tag information.

[0026] To achieve one of the above-mentioned objectives, an embodiment of the present invention provides a storage device, comprising:

[0027] A storage compartment for storing bottles;

[0032] Compared with the prior art, the present invention has the following beneficial effects: the application of this method can prevent the wine cabinet from the problem of wine bottles being misidentified, because when the wine bottle is full of wine, the first label information cannot be identified. If it is identified, it means that there is no wine or only a small amount of wine in the bottle. In the scenario where the user does not place an empty bottle in the wine cabinet by default, it can be determined that the wine bottle detected at this time is a wine bottle outside the wine cabinet; in addition, the small amount of electromagnetic waves leaked outside the wine cabinet will cause signal attenuation due to the liquid in the wine bottle, so when only the second label information is obtained, it can be determined that it is a wine bottle inside the wine cabinet, thereby achieving accurate judgment of whether the wine bottle belongs to the wine cabinet.

[0037] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by those skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0038] An embodiment of the present invention provides a storage device, a bottle identification method and an apparatus for the storage device, and the method can be used to accurately identify bottles located in the storage device.

[0039] A storage device can be a cabinet, refrigerator, wine cabinet, freezer, or other storage device. This embodiment uses a wine cabinet as an example, and all wine cabinets mentioned below are considered a type of storage device. A bottle can store wine, beverages, milk, and the like. In this embodiment, the bottle is used as an example, and the bottle is a wine bottle. The wine bottle 200 can contain red wine. In other words, this embodiment targets a scenario where a wine cabinet 100 stores multiple wine bottles 200 and identifies the wine bottles 200 within.

[0040] The bottle includes a bottle body 201, and a first RFID tag 202 and a second RFID tag 203 attached to and corresponding to the bottle body 201. The first RFID tag 202 corresponds to the first tag information, and the second RFID tag 203 corresponds to the second tag information. The bottle body 201 is used to hold liquids. For example, in the case of a red wine bottle 200, the bottle body 201 contains red wine. The first RFID tag 202 is primarily used to confirm the status of the bottle body 201, while the second RFID tag 203 is primarily used to confirm specific information about the bottle body 201, such as the production date, content, origin, and expiration date of the red wine.

[0041] When the bottle is full of liquid, the first RFID tag 202 cannot be identified by RFID, while the second RFID tag 203 can. The first RFID tag 202 has poorer performance, while the second RFID tag 203 has better performance. When the bottle 201 is full of liquid, the first RFID tag 202 cannot be identified due to the poor signal superposition performance of the liquid attenuation. However, the second RFID tag 203, while attenuated by the liquid, can still be detected due to its superior performance. When the bottle is empty, both the first and second RFID tags 202 and 203 can be detected. Here, "full" means that the bottle remains unsealed. For example, when a wine bottle 201 is unopened, a small amount of gas may be present at the top. A full bottle is considered full when the wine content reaches or is within the specified capacity on the label. However, it can also be completely full.

[0042] The storage device of this embodiment, namely the wine cabinet 100, may include a storage compartment 10 and a radio frequency module 20. The storage compartment 10 is used to store bottles; the radio frequency module 20 is used to obtain the radio frequency tag signal of the radio frequency tag; the radio frequency module 20 is arranged in the storage compartment 10, and performs radio frequency identification on the bottles stored in the storage compartment 10, such as wine bottles 200, to identify the radio frequency tags on the bottles.

[0043] Before introducing the recognition method, let's first explain the background of the recognition method:

[0044] First, by default, the wine cabinet 100 is used to store wine bottles 200 that are filled with wine. When the bottles are empty or only a small amount of wine is left inside, it is deemed that the user will not place such bottles in the wine cabinet 100. As for how much wine is considered a small amount of wine and how much wine is considered a full bottle, the parameters can be adjusted as needed and the corresponding first radio frequency tag 202 can be selected. For example, more than half of the wine is considered a full bottle, and less than half of the wine is considered an empty bottle. When the stored wine is more than half, the first radio frequency tag 202 cannot be recognized, but it can be recognized when it is less than half.

[0045] Second, when the wine bottle 200 is placed outside the wine cabinet 100, the leaked electromagnetic wave itself is small, and the signal attenuation caused by the full bottle of wine. Although the second RFID tag 203 has better performance than the first RFID tag 202, the second RFID tag 203 cannot be identified. The first RFID tag 202 and the second RFID tag 203 can only be identified when the bottle is empty outside the wine cabinet 100.

[0046] The following combination Figure 1 , illustrating an identification method provided by an embodiment of the present invention. Although the present application provides method operation steps as shown in the following implementation manner or flowchart, based on routine or no creative labor, the execution order of the steps in the method that do not logically have necessary causal relationships is not limited to the execution order provided in the implementation manner of the present application.

[0047] Specifically, the bottle identification method for storage equipment includes the following steps:

[0048] Obtain radio frequency tag signals;

[0049] When the radio frequency tag signal includes the first tag information, determining that the bottle is a bottle outside the storage device;

[0050] When the radio frequency tag signal contains only the second tag information, it is determined that the bottle is a bottle inside the storage device.

[0051] When the RFID tag signal includes the first tag information, it means that the first RFID tag 202 can be detected. However, the performance of the first RFID tag 202 is poor and it will not be detected when the bottle is full. In other words, if it is detected, it means that the bottle is empty at this time. Considering that an empty bottle will not be placed in the wine cabinet 100, it means that the bottle body is placed outside the wine cabinet 100 at this time.

[0052] When the RFID tag signal only carries the second tag information, it means that the first RFID tag 202 cannot be detected. At this time, the bottle may be full. Since the second tag information is detected, the wine bottle 200 placed outside the wine cabinet 100 cannot be detected when it is full. Therefore, the bottle is inside the wine cabinet 100 at this time.

[0053] In addition, when the RFID tag signal includes both the first tag information and the second tag information, the bottle is determined to be located outside the storage device. When the first tag information is detected, the second RFID tag 203 may also be detected due to its superior performance, and the bottle is determined to be located outside the storage device.

[0054] Furthermore, if the bottle is determined to be outside the storage device, the RFID tag signal is discarded. The purpose of this identification method is to count the wine bottles 200 located inside the wine cabinet 100. For wine bottles 200 outside the wine cabinet 100, the wine bottles 200 are ignored and the RFID tag signal is discarded.

[0055] Furthermore, the first tag information includes specific information;

[0056] Also includes the steps:

[0057] When the radio frequency tag signal includes the specific information, it is determined that the bottle is a bottle outside the storage device.

[0058] The specific information may be a string of specific characters or numbers. When these characters and numbers are detected, it is determined that the first radio frequency tag 202 is detected, which facilitates the determination of the wine bottle 200 located outside the wine cabinet 100 .

[0059] The first RFID tag 202 can be attached to the bottom of the bottle body 201 to avoid the problem of a wine bottle 200 placed inside the wine cabinet 100 being mistakenly identified as an empty bottle outside the wine cabinet 100. For example, even if the wine bottle 200 is unopened and full, or only a small amount of wine has been removed but is still roughly full, if the first RFID tag 202 is at a high position, it may no longer be in contact with the wine. As a result, when it is detected by the RFID module 20 inside the wine cabinet 100, it will be mistakenly identified as an empty bottle outside the wine cabinet 100. Therefore, attaching the first RFID tag 202 to the bottom of the bottle body 201 can avoid this problem.

[0060] Furthermore, the method further comprises the steps of:

[0061] If the bottle is determined to be inside the storage device, the second tag information is recorded. The second tag information is useful information for marking detailed information about the wine bottle 200. The purpose of the identification method is also to collect information from the wine cabinet 100. Therefore, if the bottle is determined to be inside the storage device, the second tag information is recorded and the information is collected.

[0062] Furthermore, the step of obtaining the radio frequency tag signal includes:

[0063] When it is detected that the door of the storage device is opened and then closed again, the radio frequency tag signal is acquired.

[0064] On the one hand, the quantity information of the wine bottles 200 may only change after being opened and closed again, so the detection is more effective at this time; on the other hand, after being opened and closed again, the door of the wine cabinet 100 is closed, which can minimize the leakage of electromagnetic waves and better detect the storage status of the wine bottles 200 inside the wine cabinet 100, avoiding the identification of wine bottles 200 outside the wine cabinet 100.

[0065] In addition, the wine bottle 200 attached with the first radio frequency tag 202 and the second radio frequency tag 203 can be a wine bottle 200 adapted for the wine cabinet 100, or can be an ordinary wine bottle 200 with labels attached by the user.

[0066] Compared with the prior art, this embodiment has the following beneficial effects:

[0067] The application of this method can prevent the wine cabinet 100 from the problem of wine bottle 200 being misidentified. When the wine bottle 200 is full of wine, the first label information cannot be identified. If it is identified, it means that there is no wine or only a small amount of wine in the wine bottle 200. In the scenario where the user does not place an empty bottle in the wine cabinet 100 by default, it can be determined that the wine bottle 200 detected at this time is the wine bottle 200 outside the wine cabinet 100; in addition, the small amount of electromagnetic waves leaked outside the wine cabinet 100 will cause signal attenuation due to the liquid in the wine bottle 200, so when only the second label information is obtained, it can be determined that it is the wine bottle 200 inside the wine cabinet 100, thereby achieving accurate judgment of whether the wine bottle 200 belongs to the wine cabinet 100.

[0072] In one embodiment, the first determination module is configured to discard the radio frequency tag signal when determining that the bottle is a bottle outside the storage device.
