[0074] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0075] Please refer to Figure 1-5 As shown, a beverage production line online monitoring and early warning method includes:

[0076] Obtain order information, including beverage quantity information and beverage specification information;

[0077] Use camera equipment to collect images of filled bottles on the production line and obtain the number of filled bottles;

[0078] Get inventory information in the warehouse;

[0079] Filter the inventory information in the warehouse according to the beverage specification information to obtain the number of filling bottles of the required specifications;

[0080] Compare the quantity of bottles and beverages of the required specifications to determine the replenishment quantity information;

[0081] Based on the required specification of the number of filling bottles and the number of beverages, the judgment is made to obtain the correction information of the number of filling bottles;

[0082] According to the filling bottle quantity correction information, an estimated value of the raw material quantity is obtained, where the estimated value of the raw material quantity includes a first estimated value of the raw material quantity and a second estimated value of the raw material quantity;

[0083] Use shooting equipment to collect video of the filling bottles on the production line and obtain the video frame information of the filling bottles;

[0084] Analyze the video frame information of the filling bottles to obtain the status information of the filling bottles on the production line;

[0085] Compare the filling bottle status information with the set value to determine the transportation status of the production line;

[0086] Determine whether to issue an alarm based on the transportation status of the production line.

[0087] It can be understood by those skilled in the art that beverage manufacturers can determine the specifications and quantities of beverages to be produced based on customer order information, determine the specifications of the filling bottles used in production based on the specifications of the beverages, and determine the number of filling bottles of this specification based on the inventory information in the warehouse. If the number of filling bottles is insufficient, it is necessary to replenish the filling bottles of this specification in the warehouse until the production is successfully completed; and during production, a camera is used to take pictures to determine the number of filling bottles on the production line, and a camera is used to record and extract video frames. The video frame extraction method uses functions in the video processing library to operate, such as cap.read(), cv2.cvtColor(frame, code) and ca. p.release() and other functions are used to obtain the status information of the filling bottles on the production line. The status information is the vibration information of the filling bottles on the production line, because the transportation status of the production line may cause the vibration of the filling bottles, and the vibration may cause the filling bottles to break. If they break, the number of filling bottles in the production line will decrease. If the staff does not replenish the filling bottles on the production line in time, production interruption may occur. Therefore, the transportation status of the production line cannot be easily ignored. The present invention analyzes the vibration of the filling bottles to obtain the transportation status information of the production line. If the vibration of the filling bottles is too large, it means that the transportation status of the production line is abnormal, an alarm is output, and the transportation of the production line is optimized. Therefore, the idea of ​​the present invention can ensure the normal production of beverages without delay.

[0088] The following steps are used to capture images of the filled bottles on the production line and obtain the number of filled bottles:

[0089] Use high-resolution industrial cameras or visual sensors to capture images of filled bottles on the production line;

[0090] Use computer vision technology to identify the filling bottles in the collected images;

[0091] Based on edge detection and segmentation, the contour of the filling bottle is detected and segmented to obtain the number of filling bottles.

[0092] It can be understood by those skilled in the art that the use of high-resolution industrial cameras or visual sensors requires the use of codecs that support high-resolution and high-quality compression (such as H.264, H.265), thereby effectively reducing the image size and improving the image processing speed. Image processing includes image denoising, enhancement, resizing, etc., identifying key feature points in the image, and using local feature descriptors (such as SIFT, SURF, ORB) to represent and describe the extracted features, thereby identifying the filled bottles. The goal of edge detection is to identify the locations of obvious brightness changes or color changes in the image. These locations usually correspond to the boundaries of objects or important features inside objects. Sobel operator, Canny edge detection and Laplacian operator are used to determine the number of filled bottles. The purpose of doing this is that in production, the pictures taken by high-resolution industrial cameras or visual sensors contain not only filled bottles, but also other objects. Therefore, the above means are used for analysis, first identifying the filled bottles in the picture, and then analyzing the number of filled bottles. If the filled bottles are broken due to vibration, the number of filled bottles on the production line must be less than the number of beverages in the order information, and the filled bottles on the production line need to be replenished in time.

[0093] The steps of filtering the inventory information in the warehouse according to the beverage specification information and obtaining the number of filling bottles of the required specifications are as follows:

[0094] Based on the inventory information, all the filling bottle information in the inventory is counted, and the filling bottle information includes the quantity and specifications of the filling bottles;

[0095] Determine the filling bottle of required specifications based on the beverage specification information;

[0096] Parse the inventory information based on the required specifications of the filling bottles to determine the location of the required specifications of the filling bottles;

[0097] The number of filling bottles is counted based on the positions of filling bottles of required specifications to obtain the number of filling bottles of required specifications.

[0098] Based on the required specification of the number of filling bottles and the number of beverages, the determination and acquisition of the filling bottle quantity correction information specifically include the following steps:

[0099] The number of bottles of required specifications is recorded as A, and the number of beverages is recorded as B;

[0100] Compare the values ​​of A and B;

[0101] If the value of A is greater than or equal to the value of B, the number of filling bottles of the required specifications is used as the filling bottle quantity correction information;

[0102] If the value of A is less than the value of B, the beverage quantity information is used as the filling bottle quantity correction information.

[0103] According to the information on the number of filled bottles, obtaining the estimated amount of raw materials includes the following steps:

[0104] If the number of filling bottles of the required specifications A is used as the filling bottle quantity correction information;

[0105] Calculate based on the number of filling bottles A and beverage specification information to obtain an estimated value of the first raw material quantity;

[0106] Among them, the specific calculation formula for obtaining the estimated value of the first raw material quantity is:

[0107] V1=D A ×V2;

[0108] Where V1 is the estimated amount of the first raw material; D A is the number of filled bottles; V2 is the beverage specification information;

[0109] If the beverage quantity information B is used as the filling bottle quantity correction information;

[0110] Calculate based on the beverage quantity information B and the beverage specification information to obtain an estimated value of the second raw material quantity;

[0111] The specific calculation formula for obtaining the estimated value of the second raw material quantity is:

[0112] V3=D B ×V3;

[0113] Where V3 is the estimated amount of the second raw material; D B is the number of filled bottles; V3 is the beverage specification information.

[0114] It is understandable to those skilled in the art that when producing beverages, one must not only consider the specifications and quantity of the filling bottles used, but also the amount of raw materials used to produce the beverages. It is worth noting here that by comparing the number A of filling bottles of the required specifications with the number B of beverages, if the value of A is greater than or equal to the value of B, it means that the filling bottles in the warehouse can support the production of beverages for the order, and the number of filling bottles A is multiplied by the beverage specification information to obtain the first raw material quantity estimate. If a filling bottle is broken during production, the raw materials originally in the broken filling bottle can no longer be used, and the first raw material quantity estimate takes into account the raw material quantity value obtained in this case; if the value of A is less than the value of B, it means that the filling bottles in the warehouse cannot support the production of beverages for the order. At this time, the raw material quantity required for the original production of the beverages for the order is calculated, which is the second raw material quantity estimate. In the case of the second raw material quantity estimate, the staff must first consider replenishing the number of filling bottles in the warehouse in a timely manner, so as to achieve smooth completion of beverage production.

[0115] Analyzing the video frame information of the filling bottles and obtaining the status information of the filling bottles on the production line specifically includes the following steps:

[0116] Slice the video frames of the filling bottles to obtain multiple groups of sliced ​​videos;

[0117] Analyze and process multiple groups of slice videos to obtain multiple groups of filling bottle shaking amplitudes;

[0118] Determine the shaking amplitude of multiple groups of filling bottles and obtain the maximum shaking amplitude;

[0119] The specific calculation formula for obtaining the maximum shaking amplitude is:

[0120]

[0121] In the formula, H m is the maximum shaking amplitude; h i is the shaking amplitude of the filling bottle; n is the number of shaking amplitudes.

[0122] According to the comparison between the filling bottle status information and the set value, the specific steps to determine the transportation status of the production line include the following:

[0123] Make judgment based on the maximum shaking amplitude and the set value;

[0124] If the maximum shaking amplitude is greater than or equal to the set value, an alarm message is output.

[0125] It can be understood by those skilled in the art that multiple groups of slices are processed on the video frames to obtain multiple groups of shaking amplitudes of the filling bottles. It should be noted that the larger the shaking amplitude, the more likely the filling bottles are to break at this amplitude. Therefore, the maximum shaking amplitude is compared with the set value. If the maximum shaking amplitude is greater than or equal to the set value, an alarm message is output to remind the staff that they need to optimize the transportation status of the production line.

[0126] According to the required specifications of the filling bottle quantity and beverage quantity information, the specific steps of determining the replenishment quantity information include:

[0127] The calculation formula to determine the margin call quantity information is:

[0128] C=C2-C1

[0129] Among them, C is the replenishment quantity information; C2 is the number of filling bottles of required specifications; C1 is the beverage quantity information.

[0130] If the value of C is greater than 0, there is no need to cover the position;

[0131] If the value of C is less than or equal to 0, it is necessary to cover the position.

[0132] An online monitoring and early warning system for a beverage production line, comprising:

[0133] The acquisition module is used to obtain order information, the number of filled bottles, the inventory information in the warehouse, the correction information of the number of filled bottles, the estimated value of the raw material quantity, the video frame information of the filled bottles, and the status information of the filled bottles on the production line;

[0134] A shooting module, which is used to capture images and videos of the filling bottles on the production line;

[0135] The replenishment module is used to compare the quantity of filling bottles of required specifications with the quantity of beverages to determine the replenishment quantity information;

[0136] The status determination module is used to compare the filling bottle status information with the set value to determine the transportation status of the production line;

[0137] Alarm module: The alarm module is used to determine whether to issue an alarm based on the transportation status of the production line.

[0138] In summary, beverage manufacturers can determine the specifications and quantities of beverages to be produced based on customer order information, determine the specifications of the filling bottles used in production based on the specifications of the beverages, and determine the number of filling bottles of this specification based on the inventory information in the warehouse. If the number of filling bottles is insufficient, it is necessary to replenish the filling bottles of this specification in the warehouse until the production is successfully completed; and during production, a camera is used to take pictures to determine the number of filling bottles on the production line, and a camera is used to record and extract video frames. The video frame extraction method uses the functions in the video processing library to operate, so as to obtain the status information of the filling bottles on the production line. The status information is the vibration information of the filling bottles on the production line, because the transportation status of the production line may cause the vibration of the filling bottles, and the vibration may cause the filling bottles to break. If they break, the number of filling bottles in the production line will decrease. If the staff does not replenish the filling bottles on the production line in time, it may cause production interruption. Therefore, the transportation status of the production line cannot be easily ignored. The present invention analyzes the vibration of the filling bottles to obtain the transportation status information of the production line. If the vibration of the filling bottles is too large, it means that the transportation status of the production line is abnormal, and an alarm is output to optimize the transportation of the production line. Therefore, the idea of ​​the present invention can ensure the normal production of beverages without delay.

[0139] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention. These changes and improvements fall within the scope of the present invention. The scope of protection claimed by the present invention is defined by the attached claims and their equivalents.
