In some examples, the online weighing system 100 includes a weighing device 110, a computing device 120 connected to the weighing device 110, and a display device 130 connected to the computing device 120.

[0023] In some examples, the computing device 120 can run a computer program that can implement an online weighing method.

[0024] In some examples, the weighing device 110 may be used to weigh a material. For example, the weighing device 110 may be an electronic scale.

[0025] In some examples, the computing device 120 is connected to the weighing device 110, and the computing device 120 can obtain the weighing data of the weighing device 110 in real time. The computing device and the weighing device can be connected through a USB interface, Bluetooth, WiFi, or RS-232 serial interface.

[0026] In some examples, the computing device 120 is connected to the display device 130, and the software application interface of the online weighing can be displayed on the display device 130. The display device 130 provides a port for human-computer interaction. The computing device 120 and the display device 13 can be integrated together, such as a laptop computer, a smart phone, a tablet computer, a smart screen device, etc. The computing device and the display device can be separated, and they are connected by a cable.

[0027] Figure 2 The architecture diagram of the online weighing system shows some other examples. For some examples, please refer to Figure 2 The online weighing system 100 further includes an identification device 111, which may include a card reader or a face recognition camera. The user can confirm the operation authorization by swiping a card or face recognition, and the task list of the authorized operator who needs to perform the weighing operation can be retrieved on the computing device 120, and the weighing can be performed through computer program instructions.

[0028] The online weighing system 100 further includes a barcode scanner 112 , which can be used to scan the barcode or QR code information of the material.

[0029] According to one aspect of the present disclosure, an online weighing method is provided, which can be implemented by a computer program executed by a processor of a computing device. Figure 3 A flow chart of an online weighing method according to some examples of the present disclosure is shown. The display device 130 can visually display the interface of the computer program, and the operator can perform human-computer operation through the interface of the computer program. In some examples, the online weighing method includes the following steps: S10: Reading a task list, the task list includes at least one task information, each task information includes at least the identity information and target weight of the work object; S20: Obtaining the actual weight obtained by performing a weighing operation on the material corresponding to the selected task information; S30: Compare the actual weight with the target weight.

[0030] The task list may contain one or more task information, for which corresponding weighing operations need to be performed. The operation object is the material that needs to be weighed as shown in the current task information. The task list specifies the weighing tasks and requirements. The current task list is considered completed only when the operator accurately weighs all the materials specified in the task list. The operator needs to perform the weighing operations one by one according to the weighing tasks specified in each task information. The task list can be stored in the memory of the computing device in the form of a spreadsheet. The user can import the task list into a computer program, and after the computer program reads the task list, the task information in the task list will be displayed in the operation interface of the computer program.

[0031] In some examples, each task information contains the identity information of the material to be weighed for each weighing operation and the corresponding target weight. The identity information and target weight of the material reflect the material and weight that need to be weighed this time. In some examples, the identity information of the material is characteristic information that can identify the material. For example, the identity information can be one or more of the material code containing characters such as numbers and / or letters, the material name, the location of the material in the material warehouse, etc. The material code can uniquely correspond to the material, and it is also convenient for digital management. Generally, people are more accustomed to identifying materials by name, which helps to verify whether the taken materials are correct when weighing. The location information of the material in the warehouse helps users quickly find the storage location of the material from the material library.

[0032] In some examples, the task information may also include one or more information of material specifications and material units.

[0033] In some examples, the task information also includes the task quantity and the processed quantity. The task quantity refers to the number of portions of the material corresponding to the identity information that need to be weighed, and the processed quantity refers to the number of portions that have been weighed.

[0034] In some examples, the task list also includes list identity information. For example, the list identity information may be a string consisting of one or more of numerical values, letters, and symbols. Different task lists can be distinguished by the list identity information, which facilitates the management of the task lists.

[0035] In some examples, the interface of the computer program may only display part of the task information. For example, the computer program may only display the identity information of the material in the task information.

[0036] In some examples, each task information displayed on the interface of the computer program has a first instruction menu, and the task information is selected by triggering the first instruction menu. After the task information is selected, the execution state of the current task information is entered, and the operator can use a weighing device to weigh the material specified in the task information, and the computing device obtains the actual weight measured by the weighing device in real time.

[0037] In some other examples, there may be only one first instruction menu. In this case, the task information is selected and the first instruction menu is triggered to select the task information.

[0038] In some examples, in response to the first instruction menu being triggered, an operating interface corresponding to the selected task information can be generated and displayed on the interface of the computer program, and the operating state can be entered. In this case, the target weight in the selected task information can be displayed on the operating interface. Of course, other information in the task information can also be displayed on the operating interface. When entering the operating interface state, the user can perform a weighing operation, and the computing device obtains the weighing data of the weighing device and the comparison result of the actual weight and the target weight in real time, and the actual weight can be displayed on the operating interface. The identity information of the material in the task information is displayed on the interface of the computer program that displays the task list, and the target weight is displayed on the newly generated operating interface, which is helpful for user operation, especially on handheld computing devices.

[0039] In some other examples, triggering the first instruction menu may not generate a work interface, and the target weight, actual weight, and status mark may be displayed in the corresponding task information on the interface displaying the task list.

[0040] The actual weight can be compared with the target weight. The target weight can be displayed on the operation interface. Taking into account the operability and efficiency of the weighing operation, the actual weight obtained by the weighing operation is allowed within the allowable range of the target weight. In some examples, the target weight includes a reference value and a tolerance, for example, the reference value is 10g, and the tolerance can be ±0.01g or ±0.1%. The computer program can calculate the absolute error or relative error between the actual weight and the target weight, and then compare it with the tolerance.

[0041] In some other examples, the target weight and tolerance may be converted into a numerical range and expressed in the form of a numerical range, such as an upper value of the target weight of 10.01 g and a lower value of 9.99 g. In this case, the computer program may compare the actual weight with the upper and lower values ​​of the target weight.

[0042] In some examples, if the actual weight is within the range of the target weight, a first state mark is formed and displayed, if the actual weight is greater than the upper limit of the allowable range of the target weight, a second state mark is formed and displayed, and if the actual weight is less than the lower limit of the allowable range of the target weight, a third state mark is formed and displayed. For example, the absolute error or relative error of the reference value of the actual weight and the target weight can be calculated, and compared with the tolerance to determine whether the actual weight is within the allowable range of the target weight. In these examples, the first state mark, the second state mark and the third state mark correspond to three different weighing results, that is, qualified, over-quantity and insufficient. The first state mark, the second state mark and the third state mark can be displayed figuratively on the interface of the computer program, such as the operation interface generated by triggering the first instruction menu. The first state mark, the second state mark and the third state mark can be marked with words, such as "qualified", "over-quantity", "insufficient" and other characters, or can be represented by colors, such as green, red, yellow. Of course, it is also allowed to use a combination of characters and colors to mark. If the second state mark or the third state mark is displayed on the interface of the computer program, the operator needs to correct the material amount of the weighing device. For example, the operator can increase or decrease the amount of material on the weighing device based on the actual weight of the material weighed for the current task displayed on the interface of the computer program and the target weight. During the correction of the material amount, the computing device can obtain the weighing results of the weighing device in real time and compare the deviation between the actual weight and the target weight until the actual weight of the material is adjusted to the acceptable level.

[0043] In some examples, if the first status mark is displayed, the current weighing operation is allowed to end, and if the second status mark or the third status mark is displayed, the current operation is prohibited from ending. For example, the operation interface has a second instruction menu. When the operation interface displays the first status mark, the second instruction menu is in a triggerable state. In response to the second instruction menu being triggered, the weighing operation results of the selected task information such as actual weight, error, etc. are submitted to the local and / or server, the weighing operation ends, and the operation interface is automatically closed or can be manually closed. When the operation interface displays the second status mark or the third status mark, it means that the actual weight of the current weighing operation is unqualified. At this time, the second instruction menu is not triggerable, that is, the result of the weighing operation cannot be submitted, the weighing operation cannot be ended, and the operation interface cannot be closed. These examples provide a fool-proof function. If the weighing accuracy does not meet the requirements, the user cannot end the weighing. This can ensure the accuracy of the weighing.

[0044] In some other examples, if the actual weight is within the permissible range of the target weight, a fourth state mark is formed and displayed, and if the actual weight is outside the permissible range of the target weight, a fifth state mark is formed and displayed. The fourth state mark and the fifth state mark are different, and the fourth state mark represents that the weighing result of executing the current task information is qualified, and the fifth state mark represents that the weighing result of executing the current task information is unqualified. The fourth state mark and the fifth state mark can be concretely displayed on the interface of the computer program, such as the operation interface generated by triggering the first instruction menu. The fourth state mark and the fifth state mark can be represented by text marks and / or colors. If the second state mark is displayed on the interface of the computer program, the operator needs to correct the material amount of the weighing device. In this case, it is necessary to display the actual weight on the interface of the computer program because it can indicate the direction of correcting the material amount. In these examples, if the operation interface displays the fourth state mark, the current weighing operation is allowed to end, and if the operation interface displays the fifth state mark, the current operation is prohibited from ending. These examples provide a foolproof function, and if the weighing accuracy does not meet the requirements, the user cannot end the weighing, which can ensure the accuracy of the weighing.

[0045] In some examples, if the weighing operation for implementing the selected task information is completed, the number of operations completed in the task information is increased by 1.

[0046] In some examples, the absolute error or relative error between the actual weight and the reference value of the target weight is calculated, and the absolute error or relative error is rated. The tolerance of the target weight can be divided into multiple ranges, which correspond to different levels. For example, when the tolerance is ±0.01g, it is divided into ±(0~0.002)g, ±(0.002~0.004)g, ±(0.004~0.006)g, ±(0.006~0.008)g, ±(0.008~0.01)g, corresponding to level five, level four, level three, level two, and level one, respectively. If the absolute error between the actual weight of a weighing operation and the reference value of the target weight is 0.001g, the error rating of the weighing operation is level five. In this way, the user's weighing operation can be evaluated.

[0047] In some examples, after all the task information in the current task list is completed, the current task list is allowed to end, otherwise the current task list is prohibited from ending. For example, the interface of the computer program displaying the task list has a third instruction menu. If the sum of the task quantities of all task information is the same as the sum of the completed quantities, the third instruction menu is allowed to be triggered and the current task list can be marked as completed; if the sum of the task quantities of all task information is not the same as the sum of the completed quantities, the third instruction menu is in an untriggerable state. This can prevent the weighing operation from being missed.

[0048] In some examples, if the number of tasks in the task information is equal to the number of operations completed, the task information is not selectable or marked to prevent the weighing operation corresponding to the task information from being repeated. Specifically, when the number of tasks in the task information is equal to the number of operations completed, the first instruction menu can become untriggerable, or the corresponding task information is marked with characters or colors on the interface displaying the task list.

[0049] In some examples, the task lists are assigned to groups, and after all the task lists in each group are completed, the group is marked as completed. The group can also add other different status mark management according to the status needs.

[0050] In some instances, when a task list is modified, a change history of the task list is generated. When the task list may need to be adjusted due to changes in upstream demand or substandard downstream production results, it has a change trace function to facilitate management and review of the task list version update history.

[0051] In some examples, computer programs support historical archive record tracing. The system records and archives all weighing process operations and change information records in real time, provides historical data query, analysis and comparison functions, facilitates retrospective query and analysis, and assists related business management needs.

[0052] In some examples, computer programs can process and organize real-time and historical data according to business needs, and provide presentation functions such as reports and static and dynamic charts, such as large-screen billboards and cockpits.
