[0074] In the technical solution disclosed herein, the user's authorization or consent is obtained before acquiring or collecting the user's item image information.
[0075] Figure 1 A schematic diagram of the structure of a continuous weighing system according to an embodiment of the present disclosure is shown.
[0076] like Figure 1 As shown, the continuous weighing system according to an embodiment of the present disclosure includes a conveying device 200, a weighing device 100, a first detector 300, a second detector 400, an image acquisition device 500, and a controller 600.
[0077] In detail, the conveying device 200 is suitable for conveying multiple items such as suitcases, parcels, and travel bags; the weighing device 100 is located below the conveying device and is used to detect the total weight of the conveying device 200 and the items on it; the first detector 300 is used to detect whether any items have entered the conveying device 200; the second detector 400 is used to detect whether any items have left the conveying device 200; and the image acquisition device 500 is used to acquire images of the items entering the conveying device 200. Since the total weight detected by the weighing device always includes the weight of the conveying device 200 itself, for ease of description, unless otherwise specified, the weight obtained by the weighing device 100 mentioned below refers to the weight of the items conveyed on the conveying device and does not include the weight of the conveying device itself.
[0078] The controller 600 is configured to: when the first detector 300 detects that the i-th item has not entered the conveyor 200, control the weighing device 100 to acquire the (i-1)-th weight of the j-th to (i-1)-th items on the conveyor 200, where i is a positive integer and j is an integer from zero to (i-1); when the first detector 300 detects that the i-th item has entered the conveyor 200 and the second detector 400 detects that none of the j-th to (i-1)-th items have left the conveyor 200, control the weighing device 100 to acquire an image of the i-th item and the i-th weight of the j-th to i-th items on the conveyor 200; and determine the weight G of the i-th item based on the i-th weight from the first detector and the (i-1)-th weight from the second detector. i ; and the image and weight G of the i-th item. i Associated storage.
[0079] According to some embodiments of this disclosure, the controller may include a control module, a calculation module, and a storage module. The control module is configured to: when the first detector 300 detects that the i-th item has not entered the conveying device 200, control the weighing device 100 to acquire the (i-1)th weight of the j-th to (i-1)-th items on the conveying device 200, where i is a positive integer and j is an integer from zero to (i-1); when the first detector 300 detects that the i-th item has entered the conveying device 200 and the second detector 400 detects that none of the j-th to (i-1)-th items have left the conveying device 200, control the weighing device 100 to acquire an image of the i-th item and the i-th weight of the j-th to i-th items on the conveying device 200. The calculation module is configured to determine the weight G of the i-th item based on the i-th weight from the first detector and the (i-1)-th weight from the second detector. i The storage module is configured to store the image and weight G of the i-th item. i Associated storage.
[0080] According to an embodiment of this disclosure, after the continuous weighing system is started, the weight displayed by the weighing device 100 after the continuous weighing system is started is set to 0. Multiple items enter the conveying device 200 in sequence. When the first item enters, the first detector 300 can detect that the first item has entered the conveying device 200, and thus the weighing device 100 detects its weight. The weight of the first item and the image of the item captured by the image acquisition device 500 are associated and stored. When the first detector 300 detects the second item entering, and the second detector 400 does not detect that any item has left the conveying device 200, the weight of the second item can be determined by using the second weight measured by the weighing device 100 and the weight of the first item.
[0081] According to an embodiment of this disclosure, when the first detector 300 detects the entry of a third item, if the second detector 400 does not detect the exit of an item from the conveying device 200, the weight of the second item can be determined by the third weight and the second weight weighed by the weighing device 100.
[0082] Similarly, according to the embodiments of this disclosure, when the first detector 300 determines that the i-th item has entered the conveying device 200, the weight of the i-1th item among the j-th to i-1th items on the conveying device 200 is combined with the weight of the items leaving the conveying device 200 among the j-th to i-1th items, and the weight of the i-th item is weighed. This enables continuous weighing of each item without constantly starting and stopping the conveying device 200, improving the efficiency of continuous weighing and thus avoiding the backlog of items caused by weighing multiple items.
[0083] In the above embodiment, the weight of the i-th item is calculated based on the situation where the first detector 300 detects that the i-th item enters the conveying device, while the second detector 400 does not detect that any item leaves the conveying device 200.
[0084] However, since the operation of placing the items to be weighed onto the conveyor device is irregular, it is possible that while the i-th item is being placed on the conveyor device, there may be one or more items on the conveyor device 200, or even no items at all. Therefore, according to a further embodiment of this disclosure, the controller 600 is further configured to: when the first detector 300 detects that the i-th item has entered the conveyor device 200, and the second detector detects that n items from the j-th to the (i-1)-th items have left the conveyor device 200, determine the weight G of the i-th item based on the weight of the i-th item, the weight of the (i-1)-th item, and the total weight of the n items. i , where n is an integer from 1 to i-1-j.
[0085] In one exemplary embodiment, the weighing device 100 has 10 items (i=10). When the 11th item enters the conveying device 200, it is determined whether any of the original 10 items have left the conveying device 200. For example, if 3 items have left, the total weight of the 4th to 10th items can be determined based on the weight of the (i-1)th item and the total weight of the three items that left (the weight of the three items that left is detected when the 1st item enters the conveying device 200, and the weights of the 2nd and 3rd items can be determined by the method disclosed herein when they enter the conveying device 200 respectively). The 11th weight includes the total weight of the 7 items that did not leave and the weight of the 11th item. Given the total weight of the 7 items and the 11th weight, the weight of the 11th item can be calculated, and the weight of the 11th item and the image can be associated and stored.
[0086] According to the embodiments of this disclosure, as can be seen from the above, if the second detector 400 detects that the first item has left the conveying device 200, the third weight weighed by the controller 600 and the weight of the first item can determine the total weight of the second and third items. Then, based on the weight of the second item obtained above, the weight of the third item can be calculated, and so on, the weight of each item can be obtained.
[0087] According to embodiments of this disclosure, when multiple items leave the conveying device 200, the total weight of the items remaining on the conveying device 200 can be calculated based on the weight of each of the items that left, and the weight of the i-th item can be calculated based on the latest obtained weight of the i-th new item entering the conveying device 200.
[0088] According to an embodiment of this disclosure, the controller 600 calculates a first intermediate weight based on the (i-1)th weight and the total weight of the nth items, and determines the difference between the (i-1)th weight and the first intermediate weight as the weight G of the i-th item. i .
[0089] According to the embodiments of this disclosure, the first intermediate weight is the total weight of the items remaining on the conveying device 200, and the weight of the i-th item can be calculated based on the total weight of the items remaining on the conveying device 200 and the i-th weight of the new items entering the conveying device 200.
[0090] According to an embodiment of this disclosure, the controller 600 determines the difference between the i-th weight and the (i-1)-th weight as the weight G of the i-th item. i .
[0091] like Figure 1 As shown, the continuous weighing system also includes a display device 700. The display device 700 is configured to display an image and weight G of the i-th item under the control of the controller 600. i .
[0092] According to embodiments of this disclosure, the display device 700 allows staff to view the weight of each item in real time, or allows the owner of the item to view the weight of their own item, so that items exceeding the weight limit can be dealt with promptly.
[0093] like Figure 1 As shown, the continuous weighing system also includes a printing device 800. The printing device 800, under the control of the controller 600, prints the image and weight G of the i-th item. i This allows for the creation of a weight report for each weighed item. For example, a printed image of the item and its weight can be attached to the item, used for archiving and retrieval, or carried by the item's owner.
[0094] According to embodiments of this disclosure, the printing device 800 can provide staff with a weight detection report so that staff can perform subsequent processing based on the report, such as calculating the error based on the report and the reported weight of the item.
[0095] According to embodiments of this disclosure, the continuous weighing system further includes an input conveying device 900. The input conveying device 900 is disposed before the inlet of the conveying device 200 and is adapted to receive the items to be weighed and transfer the received items to the conveying device 200.
[0096] According to embodiments of this disclosure, the input terminal of the input conveying device 900 can be connected to other conveying devices. The configuration of the input conveying device 900 avoids the problem of low weighing efficiency caused by manually placing items sequentially.
[0097] like Figure 1 As shown, the continuous weighing system also includes a third detector 1001 and a disinfection device 1002. The third detector 1001 is used to detect whether an item has entered the input conveying device 900. The disinfection device 1002 is configured to disinfect the item located on the input conveying device 900 under the control of the controller 600 when the third detector 1001 detects an item on the input conveying device 900. For example, the disinfection device includes an ultraviolet radiation lamp, a disinfectant spraying device, etc.
[0098] According to embodiments of this disclosure, the use of disinfection equipment 1002 can prevent the impact on personal health caused by bacteria or viruses remaining on the items when items are transferred between multiple people (including staff and owners of the items).
[0099] According to embodiments of this disclosure, the continuous weighing system further includes an output conveying device 1100. The output conveying device 1100 is disposed after the outlet end of the conveying device 200 and is adapted to receive and transfer items from the conveying device 200.
[0100] According to embodiments of this disclosure, the output conveying device 1100 can avoid the problem of manual handling when each item leaves the conveying device 200, thereby reducing labor costs and improving work efficiency.
[0101] According to embodiments of this disclosure, at least one of the conveying device 200, the input conveying device 900, and the output conveying device 1100 includes a belt conveyor or a roller mechanism including a drive motor and a rotating roller that rotates under the drive of the drive motor.
[0102] According to embodiments of this disclosure, when the above-described equipment is manufactured using a roller mechanism, the roller mechanism includes at least one driving roller, a driven roller, and a conveyor belt.
[0103] like Figure 1 As shown, the continuous weighing system also includes a support frame 201, a first gantry 202, a second gantry 203, and a third gantry 204. It can be understood that, depending on the actual working conditions, the support frame 201 can be configured to facilitate the user's placement or removal of items. If the items being weighed are generally heavy, the support frame can be configured to be roughly level with the ground or slightly higher than the ground.
[0104] Weighing device 100, input conveying device 900, and output conveying device 1100 are mounted on support frame 201. First gantry 202 is mounted on support frame 201 and located at the entrance end of conveying device 200; first detector and image acquisition device 500 are mounted on first gantry 202. Second gantry 203 is mounted on support frame 201 and located at the exit end of conveying device 200; second detector is mounted on second gantry 203. Third gantry 204 is mounted on support frame 201 and located at input conveying device 900; third detector 1001 and disinfection device 1002 are mounted on third gantry 204.
[0105] According to an embodiment of this disclosure, when an item enters the conveying device 200, upon passing through the detection area of the third detector 1001 and being detected by the third detector, the controller controls the disinfection device 1002 to disinfect the item. The item then continues to move, and if the first detector 300 on the first gantry 202 detects the item, the aforementioned continuous weighing method is executed. The image acquisition device 500 can acquire an image of the item. If the second detector on the second gantry 203 detects that the item is located within the detection area of the second detector 400, it can be determined that the item has left the conveying device 200.
[0106] According to embodiments of this disclosure, any one of the first detector, the second detector, and the third detector 1001 includes a light emitter and a light receiver. In another alternative embodiment, any one of the first detector, the second detector, and the third detector 1001 may include a laser with a laser emitter and a laser receiver, the laser receiver determining the presence of an item based on the intensity of the laser light emitted by the laser emitter toward the transmitting device after reflection. For example, the laser may include a single-line laser.
[0107] In some embodiments, a light emitter is mounted on one column of the first gantry 202, the second gantry 203, or the third gantry 204, and is adapted to emit a light beam. A light receiver is mounted on another column of the first gantry 202, the second gantry 203, or the third gantry 204, and is adapted to receive the light beam emitted from the light emitter. In some embodiments, if any of the first detector, the second detector, and the third detector 1001 includes a laser with detection capabilities as described above, the laser may be mounted on the crossbeam of the gantry.
[0108] According to an embodiment of this disclosure, when an item enters (or leaves) the conveying device 200, a light emitter on the column emits a light beam. Due to the obstruction of the item, the light receiver cannot receive the corresponding light beam, thereby determining that an item has moved into the detection area of the detector.

[0110] like Figure 1 As shown, the embodiments of this disclosure provide a continuous weighing method, which is applied to the continuous weighing system described in any of the above embodiments. The continuous weighing system includes a weighing device 100 and a conveying device 200 disposed on the weighing device 100. The method includes steps S100 to S400.
[0111] Step S100: If the first detector 300 determines that the i-th item has not entered the conveying device 200, the controller 600 controls the weighing device 100 to obtain the (i-1)-th weight of the j-th to (i-1)-th items on the conveying device 200, where i is a positive integer and j is an integer from zero to (i-1).
[0112] Step S200: When the first detector 300 determines that the i-th item has entered the conveying device 200, and the second detector 400 determines that none of the j-th to i-1 items have left the conveying device 200, the controller 600 controls the weighing device 100 to acquire the image of the i-th item and the i-th weight of the j-th to i-th items on the conveying device 200.
[0113] Step S300: The controller 600 determines the weight Gi of the i-th item based on the i-th weight and the (i-1)-th weight.
[0114] Step S400: Controller 600 sends the image and weight G of the i-th item. i Associated storage to simultaneously display or print the image and weight G of the i-th item. i This allows staff or owners of items to intuitively know the weight of the items.
[0115] According to embodiments of this disclosure, the image may be a code corresponding to an item, which may be a code obtained by recognizing a barcode on the item.
[0116] According to embodiments of this disclosure, such as Figure 3 As shown, the weighing device 100 is set to display a weight of 0 after the continuous weighing system is started. Figure 4As shown, after the first item enters the conveyor 200, the weighing device 100 detects the weight of the first item and simultaneously acquires an image of the item so that the image and weight of the first item can be associated and stored, such as... Figure 5 As shown, when the second item enters the conveyor 200 and the first item has not left the conveyor 200, the weight detected by the weighing device 100 is the sum of the weights of the first and second items. The weight of the second item can be determined based on the sum and the weight of the first item.
[0117] According to the embodiments of this disclosure, by determining that the i-th item enters the conveying device 200, the weight of the i-1th item is determined by combining the weight of the j-th to i-1th items on the conveying device 200 and the weight of the items leaving the conveying device 200 among the j-th to i-1th items. This enables continuous weighing of each item without constantly starting and stopping the conveying device 200, improving the efficiency of continuous weighing and thus avoiding the backlog of items caused by weighing multiple items.

[0124] In one exemplary embodiment, the total weight of the n items is the total weight of the three departing items mentioned above. The total weight of the 4th to 10th items, i.e., the first intermediate weight, can be determined based on the weight of the (i-1)th item and the total weight of the n items. Thus, the weight G of the i-th item is determined based on the difference between the (i-1)th item and the first intermediate weight. i .
[0125] According to embodiments of this disclosure, the weight G of the i-th article is determined based on the i-th weight and the (i-1)-th weight. i It includes the following steps:
[0126] The difference between the weight of the i-th item and the weight of the (i-1)-th item is defined as the weight G of the i-th item. i .
[0127] In one exemplary embodiment, when no items leave the conveying device 200, the (i-1)th weight is the sum of the weights of the (i-1)th items, and the ith weight is the sum of the weights of the ith items. The difference between the two is the weight G of the ith item. i .
[0128] According to embodiments of this disclosure, the continuous weighing method further includes the following steps:
[0129] Step S500: Display the image and weight G of the i-th item.i .
