Description

Technical Field

[0001] The present invention relates to the technical field of winemaking management, and in particular to a method for non-contact precise measurement using radar technology. Background Art

[0002] In the production process, especially in the process of collecting new wine, counting, counting, and packaging for shipment, wine-making enterprises inevitably need to frequently store and retrieve wine from wine jars. The number of wine jars is huge, and the number of operations is cumbersome. To accurately record and save such a large number of wine jars and their frequent operation data in real time is a task with huge workload and data volume. If these data are not accurately recorded and saved in real time, it is impossible to accurately grasp the actual inventory and dynamic data of each wine jar. It is also impossible to accurately grasp the accurate inventory and dynamics of the entire wine warehouse. In actual work, we can only understand a rough number and then rely on estimates to estimate the amount of wine.

[0003] At present, winemaking enterprises basically adopt the method of filling first, then recording, and then labeling. After the work is completed, the data is collected and summarized and entered into the ERP. In this way, manual recording and labeling are adopted, which is easy to cause filling errors and labeling errors. At the same time, paper labels are very easy to get dirty, damp, dripped with wine, blurred, aged, or even fall off and cannot be used in the reservoir environment, resulting in data errors. In addition, when storing and retrieving wine, it is impossible to make an operation plan for the wine jar in advance. Even if a plan is made, it is impossible to make a one-to-one correspondence between the plan and the wine jar in actual operation. Furthermore, it is difficult to accurately determine which wine jar to store and retrieve wine, and the randomness is large. Especially when there is wine stored in the wine jar, it is even more difficult to know in a timely and accurate manner how much was originally stored, how much was loaded this time, or how much was extracted, and how much is left. It is basically a mess.

[0004] When taking inventory of the contents of a wine jar, a common method is to measure the depth of the wine jar with a ruler and then calculate the weight of the wine jar, but this method is labor-intensive. Summary of the invention

[0005] The technical problem solved by the present invention is to provide a method for non-contact precise measurement using radar technology, which can calculate the wine information in the wine jar through non-contact detection.

[0006] The basic solution provided by the present invention is a method for non-contact precise measurement using radar technology, comprising the following steps:

[0007] S1. A radar is arranged on the wine jar to scan the inside of the wine jar, obtain the distance between the mouth of the wine jar and the liquid surface of the wine, and calculate the height of the liquid surface in the wine jar according to the distance between the mouth of the wine jar and the liquid surface of the wine;

[0008] S2. Calculate the volume of the wine in the wine jar according to the height of the liquid level in the wine jar and the preset wine jar model, and calculate the weight of the wine according to the volume of the wine;

[0009] S3, the distance between the mouth of the wine jar and the liquid surface of the wine, the liquid surface height, the volume of the wine and the weight of the wine are packaged to generate wine jar information, and the wine jar information is uploaded to the server in real time;

[0010] S4. Display the wine jar information of each wine jar in real time through a large visual screen.

[0011] The principle and advantage of the present invention are: by setting up a radar, according to the detection result of the radar, the page height in the wine jar is obtained, and according to the liquid level in the wine jar, the volume of the wine in the wine jar and the weight of the wine are calculated to complete the inventory of the wine in the wine jar. At the same time, the height, volume and weight of the wine are packaged and uploaded, and the wine information is displayed in real time through a large visual screen, which helps managers to view the data in each wine jar in real time, thereby helping staff to record and inventory the wine information in the wine jar more easily.

[0012] Further, the S1 comprises the following steps:

[0013] S11, setting a high-precision liquid level radar at the mouth of the wine jar, and obtaining the distance between the mouth of the wine jar and the liquid surface of the wine measured by the high-precision liquid level radar;

[0014] S12. Calculate the height of the liquid level of the wine in the wine jar according to the preset height of the wine jar:

[0015] L=H1-H2

[0016] Where L is the liquid level of the wine, H1 is the height of the wine jar, and H2 is the distance between the mouth of the wine jar and the liquid level of the wine measured by the high-precision liquid level radar.

[0017] By measuring the height of the wine jar and the distance between the mouth of the jar and the surface of the wine, the height of the wine in the jar can be calculated.

[0018] Further, the S2 comprises the following steps:

[0019] S21, pre-scanning the interior of the wine jar with a 3D scanner to obtain point cloud data of the interior of the wine jar, and establishing a 3D model of the wine jar based on the point cloud data of the interior of the wine jar;

[0020] S22, counting the shape of the wine jar according to the three-dimensional model of the wine jar to see whether it is regular;

[0021] S23, when the wine jar has a regular shape, perform the following steps:

[0022] S231. Calculate the volume of the wine according to the cross-sectional area of ​​the wine jar and the height of the wine page:

[0023] V 酒 =S×L

[0024] Where V 酒 is the volume of the wine, and S is the cross-sectional area of ​​the wine jar.

[0025] The point cloud data inside each wine jar is scanned in advance by a 3D scanner, and modeling is performed based on the point cloud data. The 3D modeling is used to determine whether the shape of the wine jar is regular. If the shape of the wine jar is regular, the volume of the wine in the wine jar can be directly calculated based on the cross-sectional area of ​​the wine jar and the liquid level of the wine.

[0026] Furthermore, the S2 further comprises the following steps:

[0027] S24. When the wine jar is irregular in shape, perform the following steps:

[0028] S241, slicing the three-dimensional model of the wine jar several times in the vertical direction to obtain several slice segments of the three-dimensional model of the wine jar, and binding the interval segments of the wine volume corresponding to each slice segment;

[0029] S242, calculating the volume of the wine in the wine jar according to the interval of the wine height measured in real time:

[0030] V 酒 =V m +V n (1-x)

[0031] Where V 酒 is the volume of the wine, V n V is the volume of the interval where the wine height is located, m V n The volume of all the following intervals, x is the volume of the wine V n The proportion of the interval segment.

[0032] For wine jars with irregular shapes, it is difficult to calculate the volume of the wine in the jars using the volume formula. In advance, the point cloud data inside each wine jar is scanned by a 3D scanner, and a model is built based on the point cloud data, and then the 3D model is sliced. Then, the volume of the wine is calculated based on the actual measured height of the slice. Through the 3D modeling and slicing method, the volume of the wine in the irregularly shaped wine jar can be quickly calculated.

[0033] Furthermore, the S2 further comprises the following steps:

[0034] S25. Calculate the weight of the wine according to its volume:

[0035] W酒 =V 酒 ×ρ 酒

[0036] where ρ 酒 is the density of the liquor.

[0037] Finally, the weight of the wine is calculated based on the volume and density of the wine.

[0038] Further, the method further comprises the following steps:

[0039] S5. Identify whether there is an abnormality based on the wine information of each wine jar in each time period. If there is an abnormality, mark the corresponding wine jar and issue an early warning.

[0040] The S5 comprises the following steps:

[0041] S51, at each time period, calculating the volume difference of the wine in the wine jar according to the wine jar information;

[0042] S52. According to the preset time interval, determine whether there is an abnormality in the volume difference of the wine in the wine jar. If there is an abnormality, mark the corresponding wine jar and send the wine jar information of the wine jar in the time period to the staff.

[0043] During the storage process, the wine will be lost due to alcohol evaporation. The volume difference in the wine jar is calculated according to the wine jar information at each time period, and the volume difference of the wine at the preset time interval is counted to see if it is normal. If it is normal, it is normal evaporation. If it is abnormal, there are other reasons that cause the loss of wine, and the staff needs to be notified for investigation.
