Based on the implementation environment shown in fig. 1(a), the embodiment of the present disclosure provides a method for detecting the weight of a target object, taking an electronic scale to execute the embodiment of the present disclosure as an example, and referring to fig. 5, the method provided by the embodiment of the present disclosure includes:

501. the electronic scale obtains an order mark of the target order and the actual total weight of each target object in the target order.

The target order is an order to be subjected to weight detection at present. The order mark of the target order is the only mark of the target order, is used for distinguishing different orders, can quickly determine and find the target order, and can be in the form of an identification code or a digital form. When the electronic scale obtains the order mark of the target order, the electronic scale can scan the identification code on the target order based on the scanning sub-module, so as to obtain the order mark of the target order; the electronic scale can also detect the input operation of the merchant on the input sub-module, and obtain the order number input by the merchant, so as to obtain the order identification of the target order.

For example, if the objects in the target order include dishes, packages, and tableware, the actual total weight is the sum of the weights of the dishes, packages, and tableware. When the target order is prepared, the merchant can place the target object corresponding to the target order on the electronic scale, and the weighing module of the electronic scale weighs each target object in the target order to obtain the actual total weight.

502. And the electronic scale acquires a preset weight range of the target order according to the order mark.

The preset weight range is a weight range within which the actual total weight of each target object in the target order is allowed to fluctuate, and can be determined according to the theoretical weight of each target object in the target order and a corresponding preset confidence interval.

In an embodiment of the present disclosure, when the electronic scale obtains the preset weight range of the target order according to the order identifier, the following method may be adopted:

50211. and the electronic scale acquires the theoretical weight of each target object in the target order and a corresponding preset confidence interval according to the order identification.

In the embodiment of the present disclosure, a merchant may input in advance an order identifier of a target order, a theoretical weight of each target object in the target order, and a preset confidence level interval of each target object, where the theoretical weight of each target object in the target order may be the same or different, and may specifically be determined according to an actual order condition, and similarly, the preset confidence level interval of each target object in the target order may be the same or different, and may specifically be determined according to an actual order condition. Based on the input operation of a merchant, the electronic scale stores the order identification of the target order, the theoretical weight of each target object in the target order and a corresponding preset confidence interval. When the order identification of the target order is obtained, the electronic scale can determine each target object in the target order according to the order identification, and further obtain the theoretical weight and the corresponding preset confidence interval of each target object in the target order.

50212. And the electronic scale multiplies the theoretical weight of each target object by the corresponding interval endpoint value of the preset confidence coefficient interval to obtain the weight difference range of each target object.

The weight difference range of the target object is the difference range allowed by the difference between the theoretical weight and the actual weight of the target object. For example, the theoretical weight of the object is 1000g, the preset confidence interval of the object is [ -10%, 10% ], and the weight difference of the object is [ -100g, 100g ].

50213. The electronic scale adds the theoretical weight of each target object to the end point values at the two ends of the corresponding weight difference range to obtain the weight range of each target object.

Wherein the weight range of the target object is the allowable weight range of the target object. For example, the theoretical weight of an object is 1000g, the difference in weight of objects is in the range of [ -100g, 100g ], and the weight of the object is in the range of [900g, 1100g ].

50214. And adding the endpoint values of the same end in the weight range of each target object by the electronic scale to obtain a preset weight range.

Adding the endpoint values of the left end in the weight range of each target object in the target order by the electronic scale to obtain the minimum value of the actual total weight of each target object in the target order; and adding end point values at the right end in the weight range of each target object in the target order by the electronic scale to obtain the maximum value of the actual total weight of each target object in the target order. Then, a preset weight range is determined based on the minimum value of the actual total weight of each object in the object order and the maximum value of the actual total weight of each object in the object order. For example, the object order includes object 1, object 2, and object 3, object 1 has a weight range of [900g, 1100g ], object 2 has a weight range of [800g, 1200g ], object 1 has a weight range of [700g, 1300g ], and the predetermined weight range of the object order is [2400g, 3600g ].

In another embodiment of the present disclosure, when the electronic scale obtains the preset weight range of the target order according to the order identifier, the following method may be adopted:

50221. and the electronic scale acquires the theoretical weight of each target object in the target order and a corresponding preset confidence interval according to the order identification.

The step is the same as the step 50211 in the specific implementation, and refer to the step 50211 in the specific implementation, which is not described herein again.

50222. The electronic scale adds the theoretical weight of each object in the target order to obtain the initial total weight of each object in the target order.

50223. And the electronic scale determines the total confidence degree interval of the target order according to the preset confidence degree interval of each target object in the target order.

In a possible implementation manner, the electronic scale may obtain a preset confidence interval with a maximum confidence value from the preset confidence intervals of the respective targets, and then use the preset confidence interval with the maximum confidence value as a total confidence interval. For example, the target object in the target order is dish 1, dish 2, and dish 3, the preset confidence interval of dish 1 is [ -1%, 1% ], the preset confidence interval of dish 2 is [ -2%, 2% ], and the preset confidence interval of dish 3 is [ -1%, 1% ], then the electronic scale obtains the preset confidence interval [ -2%, 2% ] with the largest confidence value from the preset confidence intervals of dish 1, dish 2, and dish 3, and then takes the preset confidence interval [ -2%, 2% ] with the largest confidence value as the total confidence interval of the target order.

In another possible implementation manner, the electronic scale may multiply the theoretical weight of each target by the interval endpoint value of the corresponding preset confidence interval to obtain the weight difference range of each target, and further add the endpoint values of the same end in the weight difference range of each target and divide the added endpoint values by the initial total weight to obtain the total confidence interval. For example, the target object in the target order is dish 1, dish 2, and dish 3, the theoretical weight of dish 1 is 1000g, the preset confidence interval is [ -10%, 10% ], the theoretical weight of dish 2 is 1000g, the preset confidence interval is [ -20%, 20% ], the theoretical weight of dish 3 is 1000g, and the preset confidence interval is [ -10%, 10% ], the electronic scale multiplies the theoretical weight of dish 1 by the interval endpoint value of the corresponding preset confidence interval to obtain the weight difference range of dish 1 [ -100g, 100g ], the electronic scale multiplies the theoretical weight of dish 2 by the interval endpoint value of the corresponding preset confidence interval to obtain the weight difference range of dish 2 [ -200g, 200g ], the electronic scale multiplies the theoretical weight of dish 3 by the interval endpoint value of the corresponding preset confidence interval, obtaining the weight difference range of the dish 3 of [ -100g, 100g ], then adding the end values of the same end in the weight difference ranges of the three targets by the electronic scale to obtain the total weight difference range of [ -400g, 400g ], further dividing the total weight difference range by the initial total weight of 3000g to obtain the total confidence degree interval of [ -13.3%, 13.3% ].

50224. And the electronic scale multiplies the initial total weight by the interval endpoint value of the total confidence interval to obtain the total mass difference range.

For example, an initial total weight of the target order of 3000g, and a total confidence interval of [ -10%, 10% ], a total mass difference range of [ -300g, 300g ] may be obtained.

50225. And adding the initial total weight and the end point values at the two ends of the total difference range by the electronic scale to obtain a preset weight range.

For example, if the initial total weight of the target order is 3000g, the total mass difference is in the range of [ -300g, 300g ], then the predetermined weight range for the target order is 2700g, 3300 g.

503. And when the actual total weight is not within the preset weight range, the electronic scale carries out error prompt on the target order.

And the electronic scale compares the actual total weight of each target object in the target order with a preset weight range, and if the actual total weight of each target object in the target order is not in the preset weight range, the electronic scale predicts that missed meals or wrong meals may exist in the target order. In order to avoid the phenomena of missed meal or wrong meal, the dining experience of the user is improved, unnecessary economic loss caused to the commercial tenant is avoided, and the electronic scale carries out error prompt on the target order so as to remind the commercial tenant of checking the target order. The method for the electronic scale to prompt the target order for the error includes, but is not limited to, at least one of the following methods:

first, a voice prompt sub-module of the electronic device prompts the merchant in a voice manner, for example, "the order weight is overweight or the order weight is insufficient, please check the order, etc.

And secondly, controlling a vibration motor to vibrate at a first preset frequency by a vibrator module of the electronic equipment so as to prompt the merchant.

And thirdly, the display sub-module of the electronic equipment controls the flash lamp to flash at a second preset frequency so as to prompt the merchant.

Of course, besides using the electronic scale to prompt the merchant, the electronic scale may also generate error prompt information, send the generated error prompt information to the terminal of the merchant (for example, the mobile phone of the merchant, the device such as a dining treasure, etc.), and then prompt the merchant by the terminal of the merchant.

Under the normal condition that missed or wrong meal does not appear, the actual total weight of target order form generally can be in predetermineeing the weight range, if when missed or wrong meal appears, the actual total weight of target order form can have great deviation and not in predetermineeing the weight range, in view of this disclosed embodiment detects through the actual total weight to each target object in the target order form, can be when the actual total weight of each target object is not in predetermineeing the weight range in the target order form, in time indicate the merchant, thereby avoid the condition that missed or wrong meal appears in the target order form, user's dining experience has been improved, avoid the merchant to receive the loss.

In another embodiment of the disclosure, if the merchant checks the target order, if the target order is found to have no missed or wrong meal, the user may perform a confirmation operation on the electronic scale, and after the confirmation operation of the merchant is detected, the electronic scale generates an order confirmation message, and in response to the order confirmation message, the electronic scale stops performing error prompt on the target order.

In another embodiment of the present disclosure, in response to the order confirmation message, it indicates that the merchant has checked that the target order does not have missed or wrong meals, the actual total weight of each target object in the target order is reasonable, and for convenience of subsequent applications, the electronic scale corrects the preset weight range of the target order according to the actual total weight, so as to reduce the false alarm rate.

In another embodiment of the present disclosure, the objects included in different orders may be mostly the same, but some objects are different, and the electronic scale may obtain the actual weight of some objects by subtracting the actual total weight of different orders, so as to obtain a rich sample. For example, if the first order includes dishes A, B and C and the second order includes dishes A, B, C and D, the actual weight of dish D can be obtained by subtracting the actual total weight of each dish in the second order from the actual total weight of each dish in the first order.

Along with the increase of the service time of a merchant, the number of samples acquired by the electronic scale is more and more abundant, and the confidence interval of dishes of the merchant calculated by the electronic scale is more and more accurate through continuous learning and correction, so that the accuracy of the detection result of the electronic scale can be continuously improved, and the problem of missing or missing meals is avoided to a great extent.

The method provided by the embodiment of the disclosure has the following application scenarios:

the electronic scale is arranged in the meal outlet cabinet on the side of the merchant in the first scene, and when the merchant takes meals, the weight of meals can be weighed through the electronic scale, so that the condition that the meals are mistakenly taken or lost is avoided.

The second scene, set up the electronic scale in customer's the cupboard of getting, when customer got meal, the quality of meal article was weighed to the accessible electronic scale to avoid missing the meal or losing the condition of meal and take place.

601. and the server receives the order identification of the target order sent by the electronic scale and the actual total weight of each target object in the target order.

After the target order configuration is completed, the electronic scale can scan the identification code on the target order based on the scanning sub-module to obtain the order identification of the target order, or obtain the order identification of the target order by detecting the order number input by the merchant on the input sub-module.

After the target order is prepared, the merchant places the target object corresponding to the target order on the electronic scale, and the weighing module of the electronic scale weighs each target object in the target order to obtain the actual total weight of each target object in the target order.

Based on the obtained order identification of the target order and the actual total weight of each target object in the target order, the electronic equipment sends the order identification of the target order and the actual total weight of each target object in the target order to the server.

In another embodiment of the present disclosure, in order to facilitate monitoring of the order configuration state of the merchant, after the order identifier of the target order and the actual total weight of each target object in the target order are obtained, the server further changes the state of the target order into a production completion state.

602. And the server acquires a preset weight range of the target order according to the order identification.

The step is the same as the step 502 when implemented specifically, and refer to the step 502 specifically, which is not described herein again.

603. And when the actual total weight is not within the preset weight range, the server sends an order error prompt message to the electronic scale.

And the server compares the actual total weight of each target object in the target order with a preset weight range, and if the actual total weight of each target object in the target order is not in the preset weight range, the server predicts that missed meals or wrong meals may exist in the target order. In order to avoid the phenomena of missed dining or wrong dining, the dining experience of the user is improved, unnecessary economic loss caused to the commercial tenant is avoided, the server generates order error prompt information and sends the order error prompt information to the electronic scale.

In another embodiment of the present disclosure, the server changes the status of the target order to a waiting for delivery status if the actual total weight of each object in the target order is within a preset weight range.

604. And when the order error prompt message is received, the electronic scale carries out error prompt on the target order.

When the order error prompt message is received, the electronic scale prompts the merchant by the prompt module, so that the merchant can check the target order in time, the phenomena of missing or wrong dining are avoided, the dining experience of the user is improved, and unnecessary economic loss caused to the merchant is avoided.
