Background
The self-help weighing consumption mode has become a currently ubiquitous consumption mode in the catering and retail industries, and the consumer can take objects by self, automatically weigh the objects by the system and settle accounts by self. The automatic weighing of the system is the basis of settlement, and the automatic weighing is based on the premise that the system can automatically identify the beginning and the end of the object taking action and accurately acquire an initial value and a final value, and then the difference value of the initial value and the final value is used as the metering value of settlement. However, as an unmanned system, the accurate acquisition of the initial value of each consumer by the system is influenced by the gravity center deviation of the weighing and sensing system, the evaporation of sold articles under natural or heating conditions, the collision of the consumer with a container, a balance and other actions; meanwhile, the object taking process is a continuous process, and the actions of taking the clamp, putting the clamp back, taking the object one or more times, stirring the object, shaking the object back and the like can influence the identification of the end of the object taking action and the accurate acquisition of the final value. In addition, the weighing sales model involves the integration and data interaction of the weighing system and the settlement system. In the prior art, the POS machine settlement system is manually input, only receives and processes one piece of data each time, and performs card swiping settlement, but under a self-service weighing consumption mode, the starting and ending of the object taking action cannot be accurately identified, the weighing system can only continuously output the data to the settlement system until the card swiping is finished, and as a result, the data processing capacity of the settlement system is extremely large, so that the phenomena of slow card swiping speed, repeated fee deduction, dead halt and the like of the vending system due to abnormal interaction logic of the weighing system and the settlement system can occur under a network environment. Therefore, under the self-service weighing consumption mode, if various object taking behaviors can be accurately identified through the change of the quantity and the quantity increasing and decreasing direction in the object taking process, the start and the end of the object taking behaviors can be intelligently judged, the stability, the accuracy and the fault tolerance of the system can be improved, and the data processing pressure of the settlement system can be reduced.

In the related art, under a self-service weighing consumption mode, the start and the end of a taking action cannot be accurately identified, the weighing system can only continuously output data to the settlement system until the card swiping is finished, so that the data processing capacity of the settlement system is extremely large, and the phenomena of slow card swiping speed, repeated fee deduction, dead halt and the like of the vending system due to abnormal interaction logic of the weighing system and the settlement system can occur under a network environment.
Based on the defects, the application provides a method for identifying the object taking behavior, which can identify the object taking behavior through the weight change in the object taking process, so as to judge the start and the end of the object taking behavior, calculate the weight of the object to be taken and lighten the data processing pressure of a settlement system.
Referring to fig. 1 and fig. 2, a flow chart of a method for identifying object taking behavior according to an embodiment of the present application is shown. It can be appreciated that the identification method of the taking behavior can be applied to the field of self-service weighing consumption, such as self-service settlement of self-service selected articles (mainly the articles to be weighed in the embodiment of the application) in an unmanned supermarket, such as self-service settlement of self-service selected dinner articles by a self-service restaurant consumer. It can be further understood that the object (i.e., the object in the following embodiments) to be picked up by the consumer in the process of identifying the object picking up behavior, and the object may be snack, vegetable, fruit, meat, etc. to be weighed when the supermarket is not occupied; in cafeterias, the target can be dishes, fruits and the like. When the object is fetched, some consumers need to use the object fetching device to fetch the object, and some objects are packaged or other objects can be fetched by hand directly, the consumers do not need to use the object fetching device to fetch the object. The following description is made of the fact that the article taking device is not required to be used when the article taking action occurs and the article taking device is required to be used when the article taking action occurs.
In one embodiment, as shown in fig. 1, a method for identifying a picking behavior, if a picking tool is not required to be used when the picking behavior occurs, may include:
s110, acquiring a first initial weight of a target object;
s120, if the weight of the target object is detected to change, acquiring the current first weight of the target object;
s130, comparing the first initial weight with the first weight, and if the weight difference between the first initial weight and the first weight is larger than a weight threshold, judging that the taking action is to start taking;
and S140, if the weight of the target object is not detected to change within the preset time, judging that the object taking action is finished, sending the product of the weight difference between the first initial weight and the first weight and the unit price to a settlement system so as to enable the settlement system to finish settlement and send a settlement completion instruction, receiving the settlement completion instruction sent by the settlement system, acquiring the current second weight of the target object, and taking the second weight as the first initial weight.
If the weight of the target object is detected to change again within the preset time length, acquiring the current third weight of the target object;
the third weight was taken as the first weight.
Specifically, the weight threshold may be set according to actual requirements, and the weight threshold may be set to 0, or may be set to an error range value (for example, a target object may be dehydrated after being placed for a period of time, resulting in weight loss, etc.). The weight threshold is smaller than the minimum weight of the target, for example, the target is chocolate with a package, and the weight threshold is smaller than the weight of one bag of chocolate.
The preset time length can be set according to actual requirements.
It will be appreciated that the weight of the target may be reset prior to the first initial weight of the target being obtained, i.e., the staff member completes the placement of the target prior to the start of the vending process and resets the target weight. It will also be appreciated that in the vending process, if the worker performs the target addition (i.e., the worker adds a new target to the container), the weight of the target needs to be reset.
After the weight reset of the target object is completed, detecting and recording that the current residual weight value (namely the first initial weight) of the target object is G 0 . It will be appreciated that the weight G of the object in this application 0 Including the weight of the object itself and the weight of the container.
If the residual weight value of the target object is changed, the changed residual weight (namely the current first weight of the target object) is recorded as G 1 。
It will be appreciated that if the first initial weight is less than the first weight, this may be caused by the operator adding the object or may be caused by an inadvertent touch with the container. If the first initial weight is greater than the first weight when the customer takes the object, the comparison result of the weight difference between the first initial weight and the first weight and the weight threshold can be used for judging whether the customer starts taking the object. If the weight difference is less than or equal to the weight threshold, determining that the customer does not begin taking the object; if the weight difference is greater than the weight threshold, it is determined that the customer is beginning to pick up the item.
If the customer starts taking the object, detecting whether the weight of the object is changed within the prediction time period, if the weight of the object is changed, the customer is still taking the current third weight of the object obtained after the change as the first weight, continuing to detect until the weight of the object is not changed within the prediction time period, and judging that the object taking of the customer is finished.
After the customer gets the article, G can be added 0 -G 1 The product of the value of (2) and the unit price of the target object is sent to a settlement system, the settlement system settles the target object taken by the customer, after the customer settles, the settlement system sends out a settlement completion instruction, and after receiving the settlement completion instruction, the current second weight of the obtained target object is taken as the first initial weight.
In the embodiment of the application, the relation between the weight difference value of the first initial weight and the first weight and the weight threshold value is compared to determine the object taking start time, then the object taking end time is determined according to whether the weight of the target object changes within the preset time, and the product of the weight difference value of the first initial weight and the first weight at the object taking start time and the unit price of the target object is sent to the settlement system to finish settlement, so that the data input quantity of the settlement system can be reduced, namely the data processing pressure of the settlement system can be reduced.
In one embodiment, as shown in fig. 2, a method for identifying an object taking action, if an object taking action is required to use an object taking device, may include:
s210, acquiring a second initial weight of the target object, wherein the second initial weight comprises the sum of the initial weight of the object to be fetched and the weight of an object fetching device;
s220, if the weight of the target object is detected to change, acquiring the current fourth weight of the target object;
s230, comparing the second initial weight with the fourth weight, and if the second initial weight is larger than the fourth weight and the weight difference between the second initial weight and the fourth weight is larger than or equal to the weight of the appliance, judging that the object taking action is to start object taking;
s240, if the weight of the target object is detected to change again, acquiring the current fifth weight of the target object;
s250, comparing the fifth weight with the fourth weight, if the fourth weight is smaller than the fifth weight and the weight difference between the fifth weight and the fourth weight is larger than or equal to the weight of the appliance and the fifth weight is smaller than the second initial weight, judging that the object taking action is finished, sending the product of the weight difference between the second initial weight and the fifth weight and the unit price to a settlement system so that the settlement system finishes settlement and sends a settlement completion instruction, receiving the settlement completion instruction sent by the settlement system, acquiring the current sixth weight of the target object, and taking the sixth weight as the second initial weight.
Optionally, before receiving a settlement completion instruction sent by the settlement system, if the weight of the target object is detected to change again, acquiring the current seventh weight of the target object;
the seventh weight is taken as the fourth weight.
If the second initial weight is smaller than the fourth weight, determining that the object taking behavior is a first behavior; the current eighth weight of the target object is obtained, and the eighth weight is taken as a second initial weight.
If the fourth weight is smaller than the fifth weight and the weight difference between the fifth weight and the fourth weight is smaller than the weight of the appliance, judging that the object taking behavior is a second behavior;
if the fourth weight is smaller than the fifth weight, the weight difference between the fifth weight and the fourth weight is larger than or equal to the weight of the appliance, and the fifth weight is equal to the second initial weight, determining that the object taking behavior is a third behavior;
if the fourth weight is smaller than the fifth weight, the weight difference between the fifth weight and the fourth weight is larger than or equal to the weight of the appliance, and the fifth weight is larger than the second initial weight, judging that the object taking behavior is a fourth behavior;
if the fourth weight is greater than the fifth weight, determining that the object taking behavior is a fifth behavior.
Specifically, in the embodiment of the present application, when the object taking action occurs, an object taking action identification method of an object taking device is required, where the object taking device may be: clamps, colander, spoons, etc. In the embodiment of the application, the object is shown by taking dishes in a cafeteria as an example, and the object taking device is shown by taking a clamp as an example.
It will be appreciated that the weight of the dish and the clamp will need to be reset before the second initial weight of the dish is obtained, i.e. the staff completes the holding of the dish and clamp before the meal selling is started, and resets the weight of the dish, and the staff picks up the clamp from the dish and returns it to the dish to record the clamp weight G Clip (i.e., appliance weight). It will also be appreciated that the clamp weight may also be set in advance for the worker. It will also be appreciated that if the clamp is replaced, the weight of the dish and clamp will also need to be reset. It will also be appreciated that during the vending process, if the staff is to perform a dish addition (i.e. the staff is to add a new dish to the dish holding appliance), the weight of the dish and the clamp also needs to be reset.
After the weight reset of the dishes and the clamp is completed, detecting and recording that the current residual weight value (namely the second initial weight) of the dishes on the meal line is G 0 . Wherein the G is 0 Is the total weight of dishes and fetching devices.
If the value of the remaining weight of the dish is changed, the changed remaining weight (namely the current fourth weight of the target object) is recorded as G 1 。
It will be appreciated that the change in the value of the remaining weight of the dish may be caused by the addition of the dish by the staff, or by the customer picking up the clamp, or by the customer inadvertently touching the dish holder, and in particular the action of picking up the dish may be determined by comparing the second initial weight with the fourth weight.
If the current dishes remainWeight G 1 (i.e. fourth weight) is greater than the second initial weight G 0 When the remaining weight of the dishes increases, the operator is judged to add the dishes (namely, the first behavior), the eighth weight of the target object is obtained, and the eighth weight is taken as the second initial weight G 0 。
If the current dish remains with the weight G 1 (i.e. fourth weight) is smaller than the second initial weight G 0 And a second initial weight G 0 And a fourth weight G 1 The weight difference of (2) is greater than or equal to the appliance weight G Clip When the remaining weight of the dish is reduced, it is determined that the customer has taken up the clamp, that is, the dish taking start (the object taking start).
It can be understood that, after the customer picks up the clamp to begin picking up the dish, the possible actions include normal picking up of the dish (the customer picks up the clamp first and then starts to clamp the dish to the dish plate, and after the meal is picked up, the clamp is put back into the dish basin and then settled), shaking back of the dish (the customer shakes back the dishes of the clamp into the dish containing device during the meal picking process), placing back the clamp without picking up the dish (the customer picks up the clamp and places back the dish containing device without picking up the dish), and the like.
It will also be appreciated that when a customer picks up the clamp, the clamp may clamp the dishes (at this point G 0 -G 1 ＞G Clip ) There may be no dish to be clipped (at this time G 0 -G 1 ＝G Clip ）。
After the dish is taken, if the weight of the target object is detected to be changed again, the residual weight after the change (namely the current fifth weight of the target object) is recorded as G 2 。
Comparison G 1 And G 2 And (3) judging the specific behavior after the object taking is started.
If G 1 ＜G 2 And G is 2 -G 1 ≥G Clip And G is 2 ＜G 0 If it is determined that the object taking is completed, the method (G 0 -G 2 ) The X unit price is sent to a settlement system, the settlement system performs settlement, a settlement completion instruction is sent after the settlement is completed, the current sixth weight of the target object is obtained again after the settlement completion instruction is received, and the sixth weight is used asIs the second initial weight.
And before receiving a settlement completion instruction sent by the settlement system, if detecting that the weight of the target object changes again, acquiring the current seventh weight of the target object, taking the seventh weight as a fourth weight, and returning to be compared with the second initial weight.
If G 1 ＜G 2 And G is 2 -G 1 ＜G Clip Judging that the back dish is dithered (namely, the second behavior), and continuously acquiring the current fifth weight G of the target object in real time 2 And continuously comparing the obtained product with the fourth weight, and judging the specific behavior after the object taking is started.
If G 1 ＜G 2 And G is 2 -G 1 ≥G Clip And G is 2 =G 0 And determining that the customer returns to the clamp to fetch no meal (namely, the third action), and returning to acquire the second initial weight of the target object again.
If G 1 ＜G 2 And G is 2 - G 1 ≥G Clip And G is 2 ＞G 0 And determining that the customer is pressing the scale or returning the dish (namely, the fourth action).
