With continued reference to FIG. 2, a flow 200 of one embodiment of a method for outputting information in accordance with the present application is shown. The method for outputting information comprises the following steps:
In the present embodiment, the execution subject of the method for outputting information (for example, the vending machine shown in fig. 1) can acquire the total weight of the items carried by the sub-racks by the target load cell. A shelf may be composed of a plurality of sub-shelves. Each sub-shelf collects weight from a load cell. Two different articles can be placed on the same sub-shelf, and the single weight of the two articles is different and is not a multiple relation. A plurality of the same articles can be placed. The target weighing sensor is used for detecting the load bearing of the sub-shelf where the object to be measured is located. This application accessible two kinds of modes weigh object weight, and one kind mode is weighed through increasing the article one by one. Another way is to weigh by reducing the items one by one. To weigh an item a, the user may add an item a to the empty sub-shelf and obtain the total weight of the items on the target sub-shelf detected by the target load cell. For example, to reduce the weight of an item, a plurality of items A are placed on the sub-shelves, and then the total weight of the remaining items is weighed after each removal of one item A.
In response to determining that the total weight has changed and that the amount of change is greater than a predetermined change threshold, a determination is made as to whether a reference value is present, step 202.
In this embodiment, the placing of item a onto the sub-shelf or the taking of item a may continue. The load cell is capable of detecting a change in the total weight of the items carried on the sub-racks, and determining whether a reference value exists if the amount of change is greater than a predetermined change threshold. This reference value is the weight of an item at the first weighing. The predetermined variation threshold is a minimum article determination threshold for determining whether or not false detection is made. Only weight changes greater than a predetermined change threshold are considered valid item weights.
In the present embodiment, the number of determinations is used to record the number of continuous weighing. This application requires weighing equal amounts in succession to be considered the weight of the article. For example, the items a are successively added to the sub-racks, and the weighing sensors detect that the amount of change in weight is equal each time, the determination times are accumulated. If the variation amounts are not equal, the number of determinations is cleared, and the reference value is reset to the new variation amount.
And step 204, responding to the judgment that the number of times is equal to the preset number threshold, and outputting the reference value as the weight of the target object.
In this embodiment, if the load cell detects equal amounts of weight change for a predetermined number of consecutive threshold values, the reference value is output as the piece weight of the target item.
And step 205, in response to the judgment times being less than the preset times threshold value, continuing to execute the detection step.
In the present embodiment, if the number of continuous weighing does not reach the predetermined number threshold, the step 201 and 206 are continuously executed. For example, the predetermined number of times threshold is 5, and if the weighing is currently continuously performed 3 times, the step 201 and 206 still need to be repeatedly performed 2 times.
And step 206, in response to that the reference value does not exist or the variation is not equal to the reference value, determining the variation as the reference value, clearing the judgment times, and continuing to execute the detection step.
In this embodiment, if the article is not weighed for the first time, or the amount of change of this time is not equal to the reference value recorded before, it indicates that the article placed this time is not the previously weighed article. The weight of the article placed this time is taken as a reference value, the determination times are cleared, and the steps 201 and 206 are continuously executed.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for outputting information according to the present embodiment. In the application scenario of fig. 3, a user places a first item a302 on one of the sub-shelves of the vending machine 300, and the target load cell 301 detects a total weight of 20 grams, which is greater than a predetermined variance threshold of 3 grams. Since article a was weighed for the first time, without a reference value, 20 grams was taken as the reference value. The number of judgments is set to 0. If the user continues to place a second item A on the sub-shelf, the target load cell detects a total weight of 40 grams, which is greater than the predetermined variance threshold of 3 grams. Since the reference value is already available, the judgment times are accumulated by comparing the change amount 20 g of the time with the reference value. If the threshold of the predetermined number of times is 2, the above-mentioned step of weighing the placed item a needs to be re-performed, it is determined that the amount of change and the reference value are equal, and the accumulated number of times of determination is equal to the threshold of the predetermined number of times, it is determined that the weight of the placed item a is 20 g. The user may also continue to place the first item B on the sub-shelf with the target load cell detecting a weight change of 35 grams, greater than the predetermined change threshold of 3 grams. Although article B was weighed for the first time, the current reference value is 20 grams of the weight of article a since article a was previously weighed. And comparing that the variation 35 g is unequal to the reference value 20 g, determining the variation 35 g as a new reference value, resetting the judgment times, continuously placing the second article B on the sub-shelf, and detecting that the weight variation 35 g is greater than the preset variation threshold value by the target weighing sensor, wherein the judgment times are reset. Since the reference value is already available, the judgment times are accumulated by comparing the variation of 35 g and the reference value. If the threshold of the predetermined number of times is 2, the above-mentioned step of weighing the placed article B is further executed again, it is determined that the amount of change and the reference value are equal, and the accumulated number of times of determination is equal to the threshold of the predetermined number of times, it is determined that the weight of the placed article B is 35 g.
The above-described embodiments of the present application provide a method for determining the weight of an item by continuously weighing the item. The unit weight and the quantity of the articles with two different weights are identified by using the single weighing sensor, so that the intelligent goods shelf can reduce the using quantity of the weighing sensors, and the overall cost of the intelligent goods shelf is reduced.
With further reference to fig. 4, a flow 400 of yet another embodiment of a method for outputting information is shown. The process 400 of the method for outputting information includes the steps of:
In the present embodiment, the execution subject (for example, the vending machine shown in fig. 1) of the method for outputting information may obtain the weight of the first item and the weight of the second item through the steps 201 and 206. Wherein, the weights of the first article and the second article are not equal and are not in integral multiple relation. Since the purpose of this embodiment is to determine the type and quantity of the items to be removed from the sub-shelves, it is necessary to weigh the original total weight of the first and second items originally placed on the sub-shelves. Only one kind of article may be placed on the sub-shelf. The number of first items and the number of second items may be directly obtained, for example, a manager places a predetermined number of first items and second items as specified at the time of tallying. The shopper then calculates which items to remove each time they are removed, so the type and quantity of items originally on the sub-shelves is known. The number of first items and the number of second items may also be calculated from the original total weight. If the original total weight is an integer multiple of the individual piece weight of the first item, it is an indication that there is no second item on the sub-shelf, only the first item, the quantity of which is the quotient of the original total weight and the individual piece weight of the first item. Considering the error factor of the reading value of the weighing sensor, an acceptable judgment tolerance value needs to be added when judging whether the weight is an integral multiple, and if the weight is within 5 grams, the condition of the integral multiple is judged to be met.
In response to determining that the original total weight has changed, a current total weight of the first item and the second item detected by the load cell is obtained, step 402.
In this embodiment, when the user removes an item from the sub-rack, the total weight detected by the load cell changes. In order to deduce which items the user walks, the current total weight of the first and second items after walking needs to be obtained.
In step 403, in response to the current total weight being an integer multiple of the individual weight of the first item, determining the quotient of the current total weight and the individual weight of the first item as the current number of the first item, and determining the current number of the second item as 0.
In this embodiment, if the current total weight is an integer multiple of the individual weight of the first item, it indicates that there is no second item on the sub-shelf, all being the first item. And the number of the first articles is the quotient of the current total weight and the individual weight of the first articles.
In step 404, in response to the total current weight being an integer multiple of the item weight of the second item, determining a quotient of the total current weight and the item weight of the second item as a current number of the second item, and determining the current number of the first item as 0.
In this embodiment, if the current total weight is an integer multiple of the individual weight of the second item, it indicates that the sub-shelf has no first item and all are the second item. And the number of the second articles is the quotient of the current total weight and the single weight of the second articles.
In this embodiment, the weight of the first article is the product of the weight of the single piece of the first article and the first predetermined value. It is first assumed that the current quantity of first items is a first predetermined value, e.g., 1. The difference between the current total weight and the weight of the first article is the sum of the weights of the second article and/or the first article. If the difference between the current total weight and the weight of the first article is an integral multiple of the weight of the single piece of the second article, the fact that no other first article exists, only one first article exists, the other articles are the second articles, and the number of the second articles is the quotient of the difference between the current total weight and the weight of the first article and the weight of the single piece of the second article.
In response to the difference between the current total weight and the weight of the first item not being an integer multiple of the individual weight of the second item, a first predetermined value is accumulated, and the first solving step is continued, step 406.
In this embodiment, if the difference between the current total weight and the weight of the first article is not an integer multiple of the weight of the individual piece of the second article, the number of the assumed first articles is increased, and whether a multiple relationship exists between the difference between the current total weight and the weight of the first article and the weight of the individual piece of the second article is continuously tried. For example, assuming that the number of first items is 1 and the other items are all second items, then it is verified whether the difference between the current total weight and the weight of 1 first item is an integer multiple of the individual weight of the second item, and if so, it is said that there is really only one first item on the sub-shelf and the others are second items. If not, the sub-shelf still has the first and second items. Assuming the first item quantity is 2, it is continued to verify whether all other items on the sub-shelf are second items. If the weight of the second article is an integral multiple of the single weight of the second article after the 2 first articles are removed, the rest of the sub-shelves except the 2 first articles are the second articles. And so on until the first article quantity and the second article quantity are identified.
In some optional implementations of this embodiment, the first anomaly information is output in response to determining that the first predetermined value is greater than the current total weight divided by the unit weight of the first article. The predetermined value is an accumulated value, which indicates that no combination meeting the conditions is found after the upper limit of the first article is tried, and other articles or foreign matters are suspected to be put on the sub-shelf and reported to the background system.
In some optional implementations of this embodiment, the method further includes: the difference between the original total weight and the current total weight is determined as a total change amount. In response to the total variation being an integer multiple of the piece weight of the first article, determining a quotient of the total variation and the piece weight of the first article as the variation amount of the first article and the variation amount of the second article as 0. In response to the total variation being an integer multiple of the piece weight of the second item, determining the quotient of the total variation and the piece weight of the second item as the variation number of the second item, and determining the variation number of the first item as 0. Setting the second predetermined value to a varying number of the first articles, performing a second solving step as follows: in response to the difference between the total variation and the weight of the first article being an integer multiple of the weight of the individual piece of the second article, determining a quotient of the difference between the total variation and the weight of the first article and the weight of the individual piece of the second article as the variation amount of the second article, wherein the weight of the first article is a product of the weight of the individual piece of the first article and a second predetermined value. In response to the difference between the total variation and the weight of the first article being not an integer multiple of the individual weight of the second article, accumulating a second predetermined value and continuing to perform the second solving step.
The basic principle of this alternative embodiment is the same as steps 401-406 except that this embodiment uses varying weights to calculate varying numbers of items. The manner of steps 401-406 may be referred to as a static lower quantity solution. Whereas the present embodiment is a dynamic number resolution. As shown in fig. 5, when an item on the weighing cell is picked up or put down, there are normally no three situations, one, n items 1 changed; secondly, n articles 2 are changed; and thirdly, the combination of a plurality of articles 1 and a plurality of articles 2 is changed. For the above situation division, the design successively determines whether the weight variation Δ is n times of the single weight of the article 1 or the article 2, and if so, increases or decreases the number of the articles 1 or 2 by the number n. If not, assuming that the quantity of the articles 1 is i and the initial value of i is 1, recording the weighed total weight-the single weight of the articles 1 multiplied by i as the weight R, and judging whether the weight R is an integral multiple of the single weight of the articles 2, wherein the multiple is n. If so, the number of the articles 1 is estimated to be changed by i, and the number of the articles 2 is estimated to be changed by n.
