[0038] The present invention specifically realizes the statistics of products flowing on the production line by obtaining the production cycle of the production line (i.e., the time required to produce a product) and counting the products input into the production line during the production cycle. Considering that when the production line is processing products, the processing speed of each processing equipment fluctuates between upper and lower limits, and the raw material input (i.e., the products input into the production line) may also have irregular pauses due to various reasons, which causes the production cycle of the production line to be constantly changing. At this time, it is necessary to measure the current production cycle of the production line in a timely manner. Therefore, the time interval of each product passing through the head end of the production line and the time interval of each product passing through the tail end of the production line are used to form the corresponding time slot code. If a time slot code is formed at the head end and a matching time slot code is detected at the tail end, the time difference can be used to timely measure the current production cycle of the production line, thereby ensuring the statistical accuracy of the products flowing on the subsequent production line.

[0039] In summary, the present invention can adapt to the irregular feeding pattern and fluctuation of product production speed on the production line without human intervention, and realizes dynamic statistics of products on the production line, thereby contributing to the optimization of production efficiency and management, such as increasing or decreasing manpower, adjusting equipment speed, and controlling output.

[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, it will be appreciated by those skilled in the art that in the embodiments of the present invention, many technical details are proposed in order to enable the reader to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical scheme claimed in the present invention can be implemented. The division of the following embodiments is for the convenience of description and should not constitute any limitation on the specific implementation of the present invention. The various embodiments can be combined and referenced with each other without contradiction.

[0046] An embodiment of the present invention relates to a statistical method for online products on a production line. The implementation details of the statistical method for online products on the production line of this embodiment are specifically described below. The following content is only the implementation details provided for easy understanding and is not necessary for implementing this solution.

[0047] The specific process of the statistical method for online products on the production line of this embodiment can be as follows: Figure 1 As shown, including:

[0048] Step 101, in the process of feeding products into the production line, sequentially obtain the first time interval between all two adjacent products when the products fed into the production line pass the head end of the production line, and the second time interval between all two adjacent products when the products pass the tail end of the production line.

[0049] Specifically, a sensor is deployed at the head end and the tail end of the production line respectively, and then in the process of feeding products into the production line, the time when each product fed into the production line passes through the head end of the production line and the time when it passes through the tail end of the production line are obtained in turn through the two sensors. Then, through the time when each product passes through the head end of the production line and the time when it passes through the tail end of the production line, the time interval between all two adjacent products fed into the production line when passing through the head end of the production line (i.e., the first time interval) and the time interval between all two adjacent products when passing through the tail end of the production line (i.e., the second time interval) are obtained in turn. Among them, the sensors set at the head end and the tail end of the production line are OMRON E3JK-DP12 sensors.

[0050] Step 102, all first time intervals and all second time intervals are stored in a first array and a second array of preset lengths in sequence; wherein the values ​​in the first array and the second array change continuously with the storage order of the first time intervals and the second time intervals.

[0051] Step 103, using the first time interval in the first array and the second time interval in the second array to generate the first time slot code and the second time slot code respectively, and obtaining the first time slot code and the second time slot code that have a matching relationship when the maximum value in the first array is greater than or equal to twice the minimum value thereof.

[0052] In one example, firstly, the first time slot code and all the second time slot codes when the maximum value in the first array is greater than or equal to twice the minimum value thereof are obtained, and then, based on the time slot allowable error preset for the second time slot code, the first time slot code and all the second time slot codes when the maximum value in the first array is greater than or equal to twice the minimum value thereof are compared to obtain the first time slot code and the second time slot code having a matching relationship. The time slot allowable error may be 1s.

[0053] In another example, after obtaining the first time slot code and all the second time slot codes when the maximum value in the first array is greater than or equal to twice the minimum value, the first time slot code and all the second time slot codes when the maximum value in the first array is greater than or equal to twice the minimum value are compared. If the first time slot code and the second time slot code are the same, it is confirmed that the first time slot code and the second time slot code are matched.

[0054] For ease of understanding, the generation process and matching process of the first time slot code and the second time slot code are illustrated below by way of example: Figure 2 As shown, taking 5 products as an example, assuming that the time interval between two adjacent products when these 5 products pass through the head end of the production line, that is, the first time interval is 5s, 5s, 10s, 5s, 15s, and the time interval between two adjacent products when passing through the tail end of the production line, that is, the second time interval is 5s±1, 5s±1, 10s±1, 5s±1, 15s±1. Define 5s as code 1, and the first time slot code 11213 can be generated through the first time interval. Assuming that the time slot allowable error is 1s, the second time slot code 11213 can be generated through the second time interval. At this time, the first time slot code is the same as the second time slot code, and it is determined that the first time interval matches the second time interval.

[0055] In another example, the first time slot code and the second time slot code that have a matching relationship when the maximum value in the first array is greater than or equal to twice the minimum value therein can also be obtained in the following manner. Assume that the first array is array a, and the values ​​in array a (i.e., the first time interval) include a0, a1, a2, a3, a4, a5, and the second array is array b, and the values ​​in array b (i.e., the second time interval) include b0, b1, b2, b3, b4, b5. A ratio coefficient is set to be x, and the value range of x is [0.01, 0.1]. When the maximum value in array a is greater than or equal to twice the minimum value in array a, array a and array b are compared by comparing the coefficient x, that is, the corresponding values ​​in array a and array b are compared. When b0=a0±x×a0 and b1=a1±x×a1 and b2=a2±x×a2…, it is confirmed that each first time interval has a corresponding second time interval, so that after the first time interval in the first array and the second time interval in the second array are used to generate the first time slot code and the second time slot code respectively, the first time slot code and the second time slot code that have a matching relationship are obtained when the maximum value in the first array is greater than or equal to twice the minimum value thereof.

[0056] Step 104 , determining the current production cycle of the production line according to the time when a plurality of products corresponding to the first time slot code and the second time slot code having a matching relationship pass through the head end of the production line and the tail end of the production line.

[0057] Specifically, if the maximum value obtained in the first array is greater than or equal to twice the minimum value, the first time slot code and the second time slot code that have a matching relationship trigger the measurement of the current production cycle of the production line, that is, based on the time when multiple products corresponding to the first time slot code and the second time slot code that have a matching relationship pass through the head end of the production line and the time when they pass through the tail end of the production line, the production cycle of the production line when multiple products flow on the production line is determined.

[0058] In a specific implementation, when determining the production cycle of a production line when multiple products flow on the production line based on the time when multiple products corresponding to the first time slot code and the second time slot code pass through the head end of the production line and the time when they pass through the tail end of the production line, first determine the production cycle of each product based on the time when the multiple products corresponding to the first time slot code and the second time slot code pass through the head end of the production line and the time when they pass through the tail end of the production line, then obtain the average and variance of the production cycles of the multiple products, and determine the current production cycle of the production line based on the average and variance of the production cycles of the multiple products, thereby ensuring the accuracy of the production cycle measurement.

[0059] Step 105, obtaining the number of products put into the production line during the current production cycle of the production line, and counting the number of products being processed on the production line.

[0060] Specifically, during the current production cycle of the production line, the number of products put into the production line is periodically counted, and the sum of the number of products put into the production line counted in all cycles is taken as the statistical result of the number of products being processed on the production line.

[0061] In a specific implementation, the number of products put into the production line in each cycle of the current production cycle of the production line is stored in a preset queue in order, and then the sum of all values ​​in the preset queue is calculated as the statistical result of the number of products being processed on the production line. Among them, the length of the preset queue is determined according to the current production cycle, and the values ​​in the preset queue change with the storage order of the number of products put into the production line in each cycle. That is, the number of products put into the production line in each production cycle is taken as a parameter and stored in the preset queue, and then a mathematical formula is used to add the elements in the preset queue (that is, the number of products put into each cycle of the production cycle), and the statistical result of the number of products on the production line can be obtained, that is, the statistical result of the products being processed on the production line.

[0062] In an example, in order to ensure the timeliness and accuracy of the data in the preset queue, the preset queue should be updated regularly and in a timely manner, that is, the value in the preset queue is updated at preset intervals according to the time when the value enters the preset queue, and the update method is: when the preset queue is full, the oldest element in the preset queue (that is, the data of the earliest period) is removed, and the data of the latest period is added to the preset queue.

[0063] In this embodiment, by obtaining the production cycle of the production line (i.e., the time required to produce a product) and counting the products put into the production line during the production cycle, the statistics of the products flowing on the production line are realized. Considering that when the production line is processing products, the processing speed of each processing equipment fluctuates between the upper and lower limits, and the raw material input (i.e., the products put into the production line) may also have irregular pauses due to various reasons, which causes the production cycle of the production line to be constantly changing. At this time, it is necessary to measure the current production cycle of the production line in a timely manner. Therefore, the time interval of each product passing through the head end of the production line and the time interval of each product passing through the tail end of the production line are used to form the corresponding time slot code. If a time slot code is formed at the head end and a matching time slot code is detected at the tail end, the current production cycle of the production line can be measured in time using this time difference, ensuring the statistical accuracy of the products flowing on the subsequent production line. In other words, this embodiment can adapt to the irregular feeding mode and product production speed fluctuations on the production line without manual intervention, and realizes the dynamic statistics of products on the production line, thereby contributing to the optimization of production efficiency and management, such as increasing and decreasing manpower, adjusting equipment speed, and controlling output.

[0064] The step division of the various methods above is only for clear description. When implemented, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the protection scope of the present invention. Adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the protection scope of the invention.

[0066] Specifically, the time acquisition module 301 is used to sequentially obtain the first time interval between all adjacent products when the products pass the head end of the production line, and the second time interval between all adjacent products when the products pass the tail end of the production line during the process of feeding products into the production line.

[0067] The time storage module 302 is used to store all first time intervals and all second time intervals in a first array and a second array of preset lengths in sequence; wherein the values ​​in the first array and the second array change continuously with the storage order of the first time intervals and the second time intervals.

[0068] The time matching module 303 generates a first time slot code and a second time slot code respectively using the first time interval in the first array and the second time interval in the second array, and obtains the first time slot code and the second time slot code that have a matching relationship when the maximum value in the first array is greater than or equal to twice the minimum value therein.

[0069] The cycle determination module 304 is used to determine the current production cycle of the production line according to the time when multiple products corresponding to the first time slot code and the second time slot code that have a matching relationship pass through the head end of the production line and the tail end of the production line.
