[0014] Determining the corresponding first liquid level height according to the first time and the corresponding second time, obtaining a plurality of first liquid level heights, and the plurality of detection data including the plurality of first liquid level heights and the corresponding plurality of first wine amounts.

[0015] Optionally, the step of determining the corresponding first liquid level height according to the first time and the corresponding second time comprises:

[0016] Calculating a time difference value of the first time and the second time, and determining a first distance of the ultrasonic wave device corresponding to the ultrasonic wave at a corresponding time relative to the liquid level of the wine in the wine jar according to the time difference value;

[0017] Determining the first liquid level height according to the first distance and a second distance, the second distance being a distance between the ultrasonic wave device and the bottom of the wine jar.

[0018] Optionally, before the step of determining the first liquid level height according to the first distance and the second distance, the method further comprises:

[0027] Furthermore, to achieve the above objectives, the present invention also provides a device for determining the amount of wine stored in a wine jar, the device comprising:

[0028] A flow meter, used to detect the amount of wine poured into the wine jar;

[0029] An ultrasonic device, used to detect the liquid level of the wine in the wine jar; and

[0030] The host computer is connected to both the flow meter and the ultrasonic device. The host computer includes a memory, a processor, and a program for determining the amount of wine stored in the wine jar, which is stored in the memory and can run on the processor.

Compared to current methods that determine the amount of wine in a wine jar by measuring its weight, this method establishes a correspondence between the liquid level height and the amount of wine, allowing the amount of wine to be calculated simply by detecting the liquid level height. This avoids the problem of large deviations between the actual amount of wine and the measured amount due to uncertain weight of the wine jar, thereby improving the accuracy of determining the amount of wine in the jar.

[0046] Among them, reference Figure 1The host comprises a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a network interface 1004, and a memory 1003. The processor 1001, the communication bus 1002, the network interface 1004, and the memory 1003 constitute the host of the wine jar wine storage amount determination device. The communication bus 1002 is used to realize the connection and communication among the components. The network interface 1004 can optionally comprise a standard wired interface, a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 1003 can be a high-speed random access memory (RAM) memory, or a stable non-volatile memory (NVM), such as a disk memory. The memory 1003 can optionally also be a storage device independent of the aforementioned processor 1001.

[0047] Those skilled in the art can understand that Figure 1 The structure shown in the figure does not constitute a limitation on the wine jar wine storage amount determination device, and can comprise more or fewer components than the figure, or combine certain components, or different component arrangements.

[0048] As Figure 1 The memory 1003 as a storage medium can comprise an operating system, a data storage module, a network communication module, a user interface module, and a wine jar wine storage amount determination program.

[0049] In Figure 1 The wine jar wine storage amount determination device mainly uses the network interface 1004 to communicate data with other devices; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1003 in the wine jar wine storage amount determination device of the application can be arranged in the wine jar wine storage amount determination device, and the wine jar wine storage amount determination device calls the wine jar wine storage amount determination program stored in the memory 1003 through the processor 1001, and executes the wine jar wine storage amount determination method provided in the embodiment of the application.

[0050] As Figure 2 In the wine jar is in the storage state, the wine jar wine storage amount determination device detects the second liquid level of the wine in the wine jar. Wherein, the host 201, the connecting line 202, the sensor 203, the wine 204, the wine jar 205, and the wine jar cover 206.

[0051] The embodiment of the application provides a wine jar wine storage amount determination method, which refers to Figure 3 , Figure 3A flowchart of a first embodiment of a method for determining the wine storage capacity of a wine jar.

[0052] In this embodiment, the method for determining the wine storage capacity of a wine jar comprises:

[0053] In step S10, a plurality of detection data of the wine jar in a wine filling state are obtained, different detection data are detected at different time, and the detection data include a first liquid level of the wine in the wine jar and a first wine quantity in the wine jar.

[0054] The wine filling state here refers to the process of putting wine into the wine jar, and specifically can be a wine conveying channel with a flow meter putting wine into the wine jar. The detection data here refers to the first liquid level and the first wine quantity, the first liquid level refers to the distance between the bottom of the wine jar and the liquid level of the wine, and the first wine quantity refers to the quantity of wine in the wine jar, which can be described by mass, weight and volume. In this embodiment, the flow meter is used to detect the first wine quantity, i.e. the volume of the wine quantity, and the ultrasonic device is used to detect the first liquid level. The data of the first wine quantity and the data of the first liquid level form a set of detection data.

[0055] In step S20, a corresponding relationship between the liquid level and the wine quantity of the wine jar is determined according to the plurality of detection data.

[0056] The corresponding relationship here is a one-to-one corresponding relationship between the liquid level and the wine quantity, which can be a mapping relationship between the liquid level and the wine quantity, or a functional relationship between the liquid level and the wine quantity. Specifically, in this embodiment, a functional relationship between the liquid level and the wine quantity is fitted according to the plurality of detection data. In other embodiments, a data table including the liquid level and the wine quantity can be established to form a corresponding relationship between the liquid level and the wine quantity.

[0057] In step S30, a second liquid level of the wine in the wine jar is detected when the wine jar is in a storage state.

[0058] The second liquid level and the first liquid level are both determined by ultrasonic method. The wine jar in the storage state here refers to the state of the wine jar after the wine filling is completed. The second liquid level here refers to the height from the bottom of the wine jar to the liquid level position in the storage state. The detection here can specifically determine the time of sending ultrasonic waves, and the ultrasonic device is used to emit ultrasonic signals and receive the ultrasonic signals reflected by the liquid level in the wine jar to record the receiving time, and the height of the second liquid level is determined according to the time of sending ultrasonic waves and the time of receiving ultrasonic waves.

[0059] In step S40, a second wine quantity stored in the wine jar is determined according to the corresponding relationship and the second liquid level.

[0060] Specifically, the second liquor amount is calculated or obtained according to the value of the second liquid level and a corresponding relationship. Specifically, the corresponding relationship can be a functional relationship between the second liquid level and the second liquor amount. The value of the second liquid level is substituted into the functional relationship to calculate the second liquor amount.

[0061] Compared with the method for measuring the weight of the liquor at present, in the embodiment, the corresponding relationship between the liquid level and the liquor amount is established, so that the liquor amount can be calculated by detecting the liquid level, direct detection of the liquor amount is avoided, and the detection efficiency is improved.

[0062] Further, based on the first embodiment, a second embodiment of the method for determining the liquor amount in a jar is provided. In the second embodiment, after the step of determining the second liquor amount in the jar according to the corresponding relationship and the second liquid level, the method further includes:

[0063] When the second liquor amount is less than or equal to a first preset threshold, an alarm signal is output.

[0064] The first preset threshold refers to the value of the liquor amount. The first preset threshold can be a fixed threshold or can be determined according to the initial liquor amount when the jar is in the storage state. The first preset threshold is less than the initial liquor amount. The alarm signal refers to a signal less than the first preset threshold. The output mode includes uploading the alarm signal to a server through wireless transmission. Specifically, in the embodiment, the initial liquor amount is 5 liters, and the first preset threshold can be set to 4 liters. When the second liquor amount is 4 liters, a signal that the second liquor amount is less than the first preset threshold is uploaded to the server through wireless transmission.

[0065] In the embodiment, during the monitoring of the long-term storage of the jar, when the liquor amount is less than the first preset threshold, the output of the alarm signal timely determines that the jar has a leakage, and the detection efficiency is improved.

[0066] Further, based on the first embodiment, a third embodiment of the method for determining the liquor amount in a jar is provided. Refer to the first embodiment. Figure 4 In the embodiment, the obtaining of the plurality of detection data when the jar is in the filling state includes:

[0067] In step S11, an ultrasonic wave is emitted towards the bottom of the jar at different first times when the jar is in the filling state, a reflection signal of the ultrasonic wave is received, a corresponding second time is recorded, and the liquor amount of the jar corresponding to the second time is obtained as the first liquor amount.

[0068] The first time is the time when the ultrasonic detection device emits ultrasonic waves, and the second time is the time when the reflected signal of the ultrasonic waves is received, which can be the reflected signal of the liquid surface of the wine. The first wine amount can be obtained by using a flow meter

[0069] In step S12, the first liquid surface height corresponding to the first time and the second time is determined, and a plurality of first liquid surface heights are obtained. The plurality of detection data includes a plurality of first liquid surface heights and a plurality of first wine amounts corresponding thereto.

[0070] The first liquid surface height corresponds to the first wine amount. Specifically, in this embodiment, the ultrasonic detection device emits ultrasonic waves at the first time and receives the ultrasonic signal at the second time, and the wine filling amount of the wine jar at the second time is the first wine amount. The first liquid surface height is determined according to the first time and the second time, and the first wine amount corresponds to the first liquid surface height. In other embodiments, the first wine amount data can be obtained by measuring the filling amount of the wine by the flow meter when the first wine amount is reached, determining the time when the ultrasonic wave is sent, and recording the time when the ultrasonic wave reflected by the liquid surface of the first wine amount is received. The first liquid surface height corresponding to the first wine amount is determined according to the first time and the second time.

[0071] In this embodiment, the first liquid surface height and the first wine amount are obtained at a plurality of times, and a plurality of detection data are formed, which improves the accuracy of the corresponding relationship between the subsequent liquid surface height and the wine amount, thereby improving the accuracy of determining the wine amount by detecting the liquid surface height.

[0072] Further, based on the third embodiment, a fourth embodiment of the method for determining the wine amount in a wine jar is provided, which refers to Figure 5 In this embodiment, the first liquid surface height corresponding to the first time and the second time is determined according to the first time and the second time.

[0073] In step S121, the time difference between the first time and the second time is calculated, and the first distance of the ultrasonic wave device relative to the liquid surface of the wine in the wine jar at the corresponding time is determined according to the time difference.

[0074] The time difference is the second time minus the first time, and the first distance is calculated according to the time difference, the speed of sound in air, and divided by two.

[0075] In step S122, the first liquid surface height is determined according to the first distance and the second distance, and the second distance is the distance between the ultrasonic wave device and the bottom of the wine jar.

[0076] The ultrasonic device herein comprises an ultrasonic wave emitting surface and an ultrasonic wave receiving end. Specifically, when the ultrasonic wave emitting surface and the ultrasonic wave receiving end are at the same height, the second distance herein can be the distance between the ultrasonic wave emitting surface or the ultrasonic wave receiving end and the bottom of the wine jar. When the ultrasonic wave emitting surface and the ultrasonic wave receiving end are not at the same height, the average of the distance between the ultrasonic wave emitting surface and the bottom of the wine jar and the distance between the ultrasonic wave receiving end and the bottom of the wine jar is calculated. The first liquid level height is obtained by subtracting the first distance from the second distance. In this embodiment, the first distance is determined by calculating the time difference, and the first liquid level height is determined according to the first distance and the second distance.

[0077] In this embodiment, the corresponding first liquid level height is determined by the first time and the corresponding second time, which can improve the accuracy of the liquid level height and thus improve the accuracy of monitoring the leakage of the wine jar during long-term storage.

[0078] Further, based on the fourth embodiment, the fifth embodiment of the method for determining the wine storage capacity of the wine jar is proposed. In this embodiment, before the step of determining the first liquid level height according to the first distance and the second distance, the method further comprises:

[0079] When there is no wine in the wine jar, a third time of sending an ultrasonic wave is determined and a fourth time of receiving the ultrasonic wave is recorded;

[0080] The second distance is determined according to the third time and the fourth time.

[0081] The third time herein refers to the time when the ultrasonic wave device emits an ultrasonic wave, and the fourth time refers to the time when the ultrasonic wave device receives the ultrasonic wave reflected by the bottom of the wine jar. The method for determining the second distance herein can be to multiply the value of the fourth time minus the third time by the propagation speed of sound in air and divide by two. In other embodiments, the second distance can be calculated using a caliper.

[0082] In this embodiment, the second distance is obtained by using the ultrasonic wave, which avoids the instrument error caused by using other instruments, thereby reducing the error of the first liquid level height.

[0083] Further, based on the third embodiment, the sixth embodiment of the method for determining the wine storage capacity of the wine jar is proposed. In this embodiment, the step of obtaining a plurality of detection data when the wine jar is in the wine filling state further comprises:

[0084] The corresponding wine filling speed of the wine jar is controlled according to different first liquid level heights, and the wine filling speed is positively correlated with the first liquid level height.

[0085] The wine injection speed herein refers to the amount of wine injected into the wine jar per unit time. In the wine injection state, the pipe opening for wine injection is at a distance from the bottom of the wine jar. During the wine injection process, if the wine injection speed is too fast, splashing of wine against the bottom of the wine jar is likely to occur. Specifically, in this embodiment, corresponding wine injection speeds are set for different first liquid levels, and when different first liquid levels are reached, the wine injection speed is adjusted to the corresponding wine injection speed. In other embodiments, a fixed wine injection speed can be used for wine injection.

[0086] In this embodiment, the corresponding wine injection speed of the wine jar is controlled according to different first liquid levels, reducing splashing and fluctuations caused by high-speed contact of wine with the wine jar. The influence of wine fluctuations on the first liquid level is avoided, and the accuracy of detecting the first liquid level is improved.

[0087] Further, based on the first embodiment, a seventh embodiment of the method for determining the wine storage capacity of a wine jar is proposed, which is described with reference to Figure 6 In this embodiment, after determining the second wine amount stored in the wine jar according to the corresponding relationship and the second liquid level, the method further includes:

[0088] Step S51: obtaining the second wine amount detected at multiple target times before the current time when the wine jar is in the storage state;

[0089] The multiple target times herein refer to multiple times of detecting the second wine amount before the current time.

[0090] Step S52: determining a change curve of the second wine amount with time according to the multiple target times and the corresponding second wine amounts;

[0091] The change curve herein reflects the change of the wine amount in the wine jar. Specifically, when the wine jar is stationary and the wine jar does not leak wine, the change curve is a straight line and the second wine amount is constant.

[0092] Step S53: when the change curve has extreme points and the number of extreme points is greater than a preset number, outputting prompt information that the wine jar is moved.

[0093] The extreme points can be maximum points or minimum points. Specifically, when the number of extreme points is greater than a preset number, it reflects that the wine in the wine jar is shaking, thereby determining that the wine jar is moved, and outputting information that the wine jar is moved. In other embodiments, when the change curve is not a straight line, information that the wine jar is abnormal is outputted.

[0094] In this embodiment, in addition to monitoring the leakage of wine in the wine jar during long-term storage, the change curve can also be used to identify whether the wine jar is moved and output information that the wine jar is moved, thereby reflecting the condition of the wine jar in a timely manner and reducing the leakage of wine caused by movement.

[0095] In addition, the embodiment of the present application further provides a storage medium, wherein the storage medium stores a wine jar wine storage amount determination program, and the wine jar wine storage amount determination program is executed by a processor to realize any one of the above-mentioned wine jar wine storage amount determination method embodiments.
