All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In the existing logistics transportation, articles purchased by a user often need to be transported through logistics transportation to reach the user. When a user receives an article, it is necessary to verify that the article is damaged or dropped. To solve the technical problem, an embodiment of the present application provides a solution, and the basic idea is as follows: the measuring terminal is matched with the server-side computing equipment in combination with the measuring terminal capable of collecting the rotational inertia or mass distribution information of the object on the bearing surface, whether the object meets the specified requirements can be detected according to the rotational inertia or mass distribution information of the object, for example, whether the object is dropped or damaged is detected, and the detection accuracy is improved.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Fig. 1a is a schematic structural diagram of a metering terminal according to an embodiment of the present disclosure. As shown in fig. 1a, the metering terminal includes: the device comprises a control platform 10 and a bearing surface 11, wherein the bearing surface 11 is connected with the control platform 10 through a rotating shaft 12.

In the present embodiment, the carrying surface 11 is used for carrying a first object to be measured, and the first object is located at a designated position of the carrying surface 11. The first object may be an article received by a current user, or may also be an article mailed by a sender through express delivery, for example, the first object may be an article itself such as a mobile phone, a computer, clothing, food, and the like; but the present invention is not limited to this.

Alternatively, as shown in fig. 1a, a clamp 13 may be disposed on the bearing surface 11, and the first object may be fixed at a designated position of the bearing surface 11 by the clamp 13. When the first object is fixed on the bearing surface 11 at a designated position, the structure thereof is schematically shown in fig. 1 b. The implementation forms of the first object and the jigs and the number of the jigs are merely exemplary and are not limited thereto. Alternatively, the clamp 13 may slide on the bearing surface 11, so as to flexibly adjust the position of the clamp 13 on the bearing surface 11 according to the actual volume of the first object, so that the clamp 13 can fix the first object on the bearing surface 11.

In the present embodiment, as shown in fig. 1a, the control platform 10 is provided with: memory 10a, processor 10b and communication component 10 c. A memory 10a for storing a computer program. The processor 10b is coupled to the memory 10a for executing a computer program for: acquiring the moment of inertia of a first object on the bearing surface 11 based on the rotation of the bearing surface 11; the rotational inertia of the first object and the object identification associated with the first object are sent to the server-side computing device through the communication component 10c, so that the server-side computing device can check the first object by combining the rotational inertia of the second object locally associated with the object identification; and receiving a check result of the first object returned by the server-side computing device through the communication component 10c, and outputting the check result, wherein the check result indicates whether the first object meets the specified requirement. Where the moment of inertia is related to the mass, mass distribution, etc. of the object.

In different application scenarios, the specification requirements may be different, and the expression form of whether the first object meets the specification requirements may also be different. For example, whether the first object meets the specified requirement may refer to: whether the first object is entirely unpacked, whether some component or components in the first object are unpacked, whether the first object is damaged, and the like, but is not limited thereto. Further, in the present embodiment, it is considered that the first object does not meet the specification requirement in any of the above-described cases.

In an alternative embodiment, as shown in fig. 1a, the control platform 10 further includes: and a screen 10 d. Accordingly, the processor 10b may control the display of the verification result on the screen 10 d.

Optionally, the control platform 10 is further provided with: the audio component 10 g. Accordingly, the processor 10b may control the audio component 10g to play the verification result.

Optionally, the associated object identifier is different according to the difference of the first object. When the first object is a commodity purchased by the buyer or a commodity with a packing box or a packing bag, the object identifier associated with the first object may be, but is not limited to, an order number when the buyer places an order, an express delivery number corresponding to a commodity sent by the merchant and corresponding to the order number, or a model number of the commodity placed by the buyer. In the embodiment of the present application, the commodity may be the commodity itself, or may include a commodity with a package.

Accordingly, the specific implementation forms of the first object and the second object are different in different application scenarios. This is exemplified below in connection with several common application scenarios.

Application scenario 1: in an application scenario of online shopping, the object identifier may be an order number when the buyer places an order, an express order number corresponding to a commodity sent by a merchant and corresponding to the order number, or a model of the commodity placed by the buyer, and the first object may be a commodity received by the user and corresponding to the object identifier, or a packaged commodity. The user refers to a user who currently receives the commodity corresponding to the object identifier, and may be a courier or a buyer in the commodity transportation process.

Accordingly, the second object may be an item corresponding to the object identifier received by a courier in front of the user, or a like item of an item corresponding to the order number sent by the merchant. Wherein, order number corresponds to express delivery order number one-to-one.

In application scenario 1, after the buyer places an order, the merchant sends out the goods corresponding to the order number to each link where the buyer receives the goods corresponding to the order number, the metering terminal provided in this embodiment may be used to measure the rotational inertia of the received goods corresponding to the order number, and send the measured rotational inertia to the server-side computing device, so that the server-side computing device can check whether the goods received in this link meet the requirements of the specified object. Therefore, in each link of commodity transportation, whether the commodities received by the user in the link are dropped or damaged can be verified. The user refers to a courier or a buyer who receives the goods corresponding to the order number in the current link. Namely, the first object is the commodity corresponding to the order number received by the current user. The second object may be a commodity sent by the seller and corresponding to the order number, or a commodity received by a courier before the current user receives the commodity corresponding to the order number.

In the application scenario 1, the verification result of the first object is specifically indicated as whether the commodity corresponding to the order number received by the user is the commodity corresponding to the order number sent by the merchant.

For example, a buyer purchases a mobile phone online and generates a corresponding order number after placing an order; the merchant sends out the corresponding mobile phone and the packaging box of the mobile phone according to the order number. Optionally, when the merchant sends the mobile phone, the metering terminal provided by the embodiment may be used to collect the rotational inertia of the mobile phone, or collect the rotational inertia of the mobile phone with the packaging box; and sending the measured moment of inertia to the server-side computing device.

Further, in the transportation process of the mobile phone, transfer or delivery can be performed through one or more couriers. When passing through each courier, the courier can measure the rotational inertia of the goods received by the courier and corresponding to the order number when the buyer places the order by using the metering terminal provided by the embodiment, and send the measured rotational inertia to the server-side computing device. Optionally, when the buyer receives a commodity corresponding to the order number when the buyer places the order, the metering terminal provided in this embodiment may also be used to measure the rotational inertia of the buyer and send the measured rotational inertia to the server-side computing device. That is, in each link of the commodity posting after the buyer places the order, the rotational inertia of the commodity can be measured, and the measured rotational inertia is sent to the server-side computing device, so that the server-side computing device can check the first object by combining the local rotational inertia of the second object associated with the order number, and further, whether the commodity is dropped or damaged can be determined in each link of the commodity transportation.

Application scenario 2: in a common logistics application scene, the object identification can be an express bill number and the like; the first object may be an item received by the user corresponding to the courier order number, or an item with packaging. The user refers to a courier or a receiver who receives the article corresponding to the express bill number in the current link. The second object may be an item corresponding to the courier number received by a courier in front of the user, or an item actually sent out by a sender.

In application scenario 2, when the sender sends out an item, there is an express bill number bound to the item. In each link from the sending of the item by the sender to the receiving of the item corresponding to the express, the measuring terminal provided by the embodiment can be used for measuring the received rotational inertia of the item corresponding to the express bill number, and sending the measured rotational inertia to the server-side computing device, so that the server-side computing device can check whether the item received in the link meets the requirement of the specified object. Therefore, in each link of article transportation, whether the article received by the user in the link is dropped or damaged can be verified. Namely, the first object is an article which is received by the current user and corresponds to the express delivery order number. The second object may be an article sent by a sender, or an article received by a courier of the current user before receiving the article corresponding to the courier order number.

In this embodiment, by using the characteristics of the rotational inertia, the mass of the object, and the mass distribution of the object, in combination with the metering terminal capable of acquiring the rotational inertia of the object on the bearing surface, and the metering terminal and the server-side computing device are matched with each other, it is possible to detect whether the rotational inertia of the object meets the specified requirements, for example, whether the object is dropped or damaged, which is beneficial to improving the accuracy of detection.

Further, the moment of inertia is not only related to the mass of the object, but also related to the mass distribution of the object, so that whether the object is wholly unpacked or not can be detected, whether internal components of the object are unpacked or damaged can also be detected according to the moment of inertia of the object, and the detection accuracy is further improved.

For example, electronic products such as mobile phones and computers may have different design levels and process levels, although the weights of the electronic products are the same. From the design aspect of electronic products, the number of each element (capacitor, inductor, chip) on the internal PCB board is different, the categories of cameras, batteries and main control chips are different, the weights are different, and the positions of each component are distributed differently. From the aspect of the technology of electronic products, in the process of processing and assembling the electronic products, the welding mode (after the PCB is tinned by a steel mesh, an element is pasted and mounted by an SMT chip mounter, and reflow soldering is performed) can cause that the quality distribution of processed finished products is different even if the mobile phones are of the same design, and further cause that the rotational inertia of the mobile phones is different. Therefore, the metering terminal provided by the embodiment can be used for measuring the rotational inertia of the electronic product to check whether the electronic product is entirely unpacked.

Furthermore, when the package is dropped due to the internal components of the electronic product, such as a screen, a fingerprint sensor and the like, the original internal components are detached and then installed. For example, when a screen of an electronic product is unpacked, an adhesive between the original screen and a back plate needs to be scooped off, coated with the adhesive, and then another screen needs to be bonded. In the process, the weight of the screen is different, the quality and the thickness of the adhesive are different, and further, the screen may deviate from the original position in the pasting process; and the different thicknesses of the adhesive may also vary. These causes can cause the mass distribution of the electronic product to change, and thus the rotational inertia of the electronic product to change. For another example, when the fingerprint sensor is replaced, the original fingerprint sensor is soldered down, and then another fingerprint sensor is soldered down after the original fingerprint sensor is coated with solder. In this process, the weight of the fingerprint sensor itself may be different due to the difference in the quality of the solder, the displacement of the soldering position, and the like. These causes can cause the mass distribution of the electronic product to change, and thus the rotational inertia of the electronic product to change. Further, since the moment of inertia is not only related to the mass of the object, but also related to the mass distribution of the object, the metering terminal provided by the embodiment can be used for detecting whether the internal components are dropped or damaged, and the detection accuracy is further improved.

It should be noted that, in the embodiments of the present application, the server-side computing device may be any device with a computing function located at the server side, and may be a single server device, a cloud server array, or a Virtual Machine (VM) running in the cloud server array. In addition, the server-side computing device may also refer to other computing devices with corresponding service capabilities, such as a terminal device (running a service program) such as a computer. In the drawings of the related embodiments of the present application, the server-side computing device is illustrated by taking a server array as an example, but is not limited thereto.

In an optional embodiment, to ensure that the placing state of the first object on the carrying surface 11 is the same as the placing state of the second object at the moment of inertia of the carrying surface 11 when the moment of inertia is collected, the processor 10b further sends, through the communication component 10c, an information request to the server-side computing device before collecting the moment of inertia of the first object, where the information request carries the object identifier, so that the server-side computing device returns the placing state information of the second object at the moment of collected moment of inertia associated with the object identifier. Further, the processor 10b receives the placing state information of the second object returned by the server-side computing device through the communication component 10c, and outputs the placing state information of the second object, so that the user can place the first object on the bearing surface 11 at the designated position according to the same placing state as the second object. Therefore, the measurement error of the rotational inertia of the first object and the second object caused by different placing states of the first object and the second object on the corresponding bearing surfaces 11 can be reduced, and the accuracy of the subsequent verification of the first object based on the rotational inertia of the first object and the second object is improved.

Optionally, the placing state information of the second object when the rotational inertia is collected may be a measurement image of the second object on the corresponding bearing surface, which is shot by a camera on the metering terminal when the rotational inertia is collected, where the measurement image includes: and when the rotational inertia of the second object is acquired, the placing state of the second object on the corresponding bearing surface is acquired. Correspondingly, the control platform 10 of the metering terminal further comprises: and a screen 10 d. The processor 10b receives the measurement image of the second object returned by the server side computing device through the communication component 10c and displays the measurement image of the second object on its screen 10 d. This allows the user to place the first object on the supporting surface 11 at a designated position in accordance with the laying state in the measurement image of the second object.

Alternatively, the control platform 10 of the metering terminal is provided with an audio component 10 g. Accordingly, the processor 10b may receive the placing state information of the second object returned by the server computing device through the communication component 10c, and control the audio component 10g to play the placing state information of the second object.

Optionally, as shown in fig. 1a, the metering terminal further comprises a camera 14. The camera 14 is communicatively connected to the processor 10b of the control platform 10. Further, if it is detected that the first object exists on the carrying surface, the processor 10b may capture a measurement image of the first object by using the camera 14, and send the measurement image of the first object to the server computing device. Wherein the measurement image of the first object includes: when the moment of inertia of the first object is collected, the placing state of the first object on the bearing surface 11 is acquired. Therefore, when the user in the next link measures the rotational inertia of the object received by the user, the measurement image of the first object uploaded in the link can be requested from the server-side computing device.

Further, a gravity sensor may be disposed on the bearing surface 11 of the metrology terminal, and when the gravity sensor detects an increase in gravity of the bearing surface 11, it is determined that the first object is present on the bearing surface 11. Alternatively, a contact sensor may be provided on the carrying surface 11 of the metrology terminal and used to detect the presence of the first object on the carrying surface 11. Or, a certain image sampling period is set for the camera 14, a timer or a counter is started to time the sampling period, and when the sampling period is reached, the camera 14 is used to acquire the relevant image of the bearing surface 11, and the acquired image is subjected to image recognition to judge whether the first object exists on the bearing surface 11.

Further, the carrying surface 11 may be a transparent carrying surface. The camera 14 is disposed at the bottom of the transparent carrying surface.

In another alternative embodiment, as shown in fig. 1a, the metering terminal further comprises: and a force application unit 15 that applies a force of a prescribed moment to the rotary shaft 12. When the force applying unit 15 applies a rotational force with a predetermined torque to the bearing surface 11, the bearing surface is rotated.

In the present embodiment, the user may manually control the force application unit 15 to apply the rotational force of the designated torque to the rotating shaft, and the processor 10b may also control the force application unit 15 to apply the rotational force of the designated torque to the rotating shaft 12.

When the metering terminal is implemented in such a manner that the force application unit 15 is manually controlled by a user to apply a rotational force of a specified torque to the spindle, the force application unit 15 comprises a first driving member (not shown in fig. 1 a). Alternatively, the first driving member may be a spring, a pulley, or the like, but is not limited thereto. The first driving member applies a rotational force to the rotating shaft 12 under the action of the rotational operation of the user, so that the rotating shaft 12 drives the bearing surface 11 to rotate. Wherein, the number of rotations of user to first driving piece corresponds with the size of appointed moment. When the first driving piece is the clockwork spring, the designated moment is the moment generated when the clockwork spring is rotated by the user through the rotation control piece to enable the clockwork spring to be full-wound. Namely, when the user rotates the clockwork spring by utilizing the rotation control piece to enable the clockwork spring to be full, the number of turns of the clockwork spring corresponds to the designated moment.

Further, when the metering terminal is implemented in a form in which the processor 10b controls the force application unit 15 to apply a rotational force of a specified torque to the rotating shaft 10g, the force application unit 15 includes a second driving member (not shown in fig. 1 a). Optionally. The second driving member may be a motor, a motor driver, and the like. Accordingly, the processor 10b may apply a rotational force to the shaft 12 via the second driving member at the metering terminal, so that the shaft 12 rotates the bearing surface 11. When the second driving member is a motor, the working parameters of the second driving member and the rotating radius of the bearing surface 11 during rotation correspond to the specified torque. Further, the operating parameters of the second drive member include: the operating power, the rotational speed, etc. of the motor, but are not limited thereto. The method specifically comprises the following steps: the commanded torque is equal to the rotational force applied to the shaft by the second drive member multiplied by the radius of rotation of the bearing surface 11 as it rotates.

In yet another optional embodiment, the metering terminal further comprises: an angular velocity sensor 16. Alternatively, the angular velocity sensor 16 may be disposed on the bearing surface 11 and communicatively coupled to the processor 10 b. During rotation of the bearing surface 11, the angular velocity sensor 16 may acquire at least one angular velocity of the bearing surface 11. Optionally, during the rotation of the bearing surface 11, the angular velocity sensor 16 may sample the angular velocity of the bearing surface 11 at a set sampling rate for a specified period of time to obtain at least one angular velocity. The designated time period may be any time period of the bearing surface 11 in the rotation process, for example, it may be a certain time period when the bearing surface 11 starts to rotate; or a certain period of time before the bearing surface 11 stops; or any time period in the rotation process, and the length of the time period can be flexibly set according to actual requirements, for example, set to 3s, 5s, 10s, and the like, but is not limited thereto. Of course, the designated time period may be the total time from the start of rotation to the stop of rotation of the carrying surface 11.

Accordingly, the processor 10b may calculate the moment of inertia of the first object based on the at least one acceleration acquired by the angular velocity sensor 16 and the above-mentioned specified moment.

Further, the carrying surface 11 can rotate on a horizontal plane, and can also rotate on a horizontal plane and a vertical plane simultaneously, namely, the carrying surface rotates in a spiral manner. Accordingly, as the bearing surface 11 is spirally rotated, the angular velocity sensor 16 may acquire the angular velocity of the bearing surface 11 in the horizontal plane and the angular velocity thereof in the vertical plane over a specified period of time at a set sampling rate.

Correspondingly, the processor 10b may perform linear regression processing on at least one angular velocity acquired by the angular velocity sensor 16 to obtain a functional relationship between the angular velocity and time corresponding to the bearing surface 11; determining the angular acceleration of the bearing surface 11 in the rotation process based on the functional relation between the angular speed of the bearing surface 11 and time; and performing numerical operation on the angular acceleration and the designated moment of the bearing surface 11 in the rotating process to obtain the moment of inertia of the first object. The specific implementation mode is as follows: and dividing the designated moment by the angular acceleration of the bearing surface in the rotating process to obtain the moment of inertia of the first object. It is worth noting that the calculated moment of inertia of the first object is the moment of inertia of the first object on one plane. When the bearing surface 11 is spirally rotated, the angular acceleration of the bearing surface in the horizontal plane and the angular acceleration of the bearing surface in the vertical plane can be respectively used to calculate the moments of inertia of the first object in the horizontal plane and the vertical plane respectively.

In the present embodiment, the server computing device 22 refers to a hardware infrastructure for data storage and data processing. The number of server computing devices 22 may be one or more. The embodiment does not limit the implementation form of the server computing device 22. For example, the server computing device 22 may be a conventional server, a cloud host, a virtual center, or the like server device. The server-side computing device 22 mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture.

Alternatively, the server-side computing device 22 decodes the encrypted data by using a preset decryption policy, and analyzes the quality distribution information of the first object and the object identifier associated with the first object.

For the description of the metering terminal 21 in data processing, reference may be made to the description of relevant contents in fig. 1a, and details are not described here again.

In an alternative embodiment, the metrology terminal 21 acquires the moments of inertia of the first object in multiple planes, i.e. the moments of inertia of the first object include their moments of inertia in multiple planes. Then, the server-side computing device 22 may calculate a root mean square error of the moments of inertia of the first object and the second object on the plurality of planes when checking the first object; and comparing and calculating whether the root mean square error is larger than a set error threshold value. Further, if the calculated root mean square error is greater than the set error threshold, it is determined that the first object does not meet the specified requirement, that is, the verification result is: the first object does not meet the specified requirements. Correspondingly, if the calculated root mean square error is smaller than or equal to the set error threshold, it is determined that the first object meets the specified requirements, that is, the verification result is: the first object meets the specified requirements. The error threshold value can be flexibly set according to the actual requirement on the verification precision, and is not limited here.

Correspondingly, if the difference value of the moment of inertia of the first object and the second object on all the planes is larger than the error threshold value on the corresponding plane, the first object is determined to meet the specified requirement, that is, the verification result is: the first object meets the specified requirements.

In yet another alternative embodiment, based on the above fig. 1a, the metering terminal 21 sends an information request to the server computing device 22 before acquiring the moment of inertia of the first object, and accordingly, the server computing device receives the information request and acquires the placement state information of the moment of inertia of the second object associated with the object identifier according to the object identifier in the information request. For the description of the placement status information, reference may be made to the related content in fig. 1a, which is not described herein again.

Further, the metering terminal 21 captures a measurement image of the first object by using its camera, and sends the measurement image of the first object to the server-side computing device. The measurement image of the first object comprises the placing state of the first object on the bearing surface when the rotational inertia of the first object is acquired. Accordingly, the server computing device 22 receives the measurement image of the first object. This facilitates requesting the server-side computing device 22 for the measurement image of the first object uploaded at this link when the user at the next link performs the moment of inertia measurement on the object it receives.

In this embodiment, by using the characteristics of the rotational inertia related to the mass and the mass distribution of the object and combining with the metering terminal capable of acquiring the rotational inertia of the object on the bearing surface, the metering terminal and the server-side computing device are matched with each other, and whether the object meets the specified requirements can be detected according to the rotational inertia of the object, for example, whether the object is dropped or damaged or whether internal components of the object are dropped or damaged is detected, which is beneficial to improving the accuracy of detection.

The following describes an exemplary process of verifying the item received by the current user by the data processing system provided in this embodiment, with reference to the logistics transportation process of the on-line shopping of the buyer shown in fig. 2 b. The current user refers to a user who currently receives the article and performs the rotational inertia measurement by using the metering terminal, and the current user may be a merchant, a courier or a buyer in middle of transportation. As shown in fig. 2b, the specific process is as follows: the merchant sends out corresponding commodities according to the order number when the buyer places an order, measures the rotational inertia of the commodities through a metering terminal at the merchant side, and sends the rotational inertia to the server-side computing equipment for recording commodity information. And then, the courier gets the goods from the door or sends the goods to a corresponding express delivery point by the merchant, the courier receiving the goods measures the rotational inertia of the goods sent by the merchant by using a metering terminal provided by the courier and sends the rotational inertia to the server-side computing equipment, so that the server-side computing equipment verifies whether the goods measured by the courier side meet the requirement of the goods measured by the merchant side based on the rotational inertia uploaded by the courier side and the rotational inertia uploaded by the merchant side. Further, in the transportation process of the goods corresponding to the order number, every time a courier transfers the goods, the current courier can measure the moment of inertia of the goods received by the current courier through the metering terminal, and the moment of inertia is uploaded to the server-side computing device, so that the server-side computing device can verify whether the goods received by the current courier are the goods sent by the merchant.

When the courier delivers the goods to the buyer, the measuring terminal equipped by the courier at present can be used for measuring the rotational inertia of the goods to be delivered, or the measuring terminal equipped by the buyer can be used for measuring the rotational inertia of the goods to be delivered, and the measured rotational inertia is uploaded to the server-side computing device, so that the server-side computing device can verify whether the goods to be delivered are the goods sent by the merchant. In this way, each link in the transportation process of the merchant from shipping to the customer's receipt can verify whether it is being unpacked or damaged.

It is worth mentioning that the first objects in fig. 2b are all the items corresponding to the order number for which the moment of inertia is currently measured. For the metering terminal at the merchant side, the first object is a commodity which is sent by the merchant when the merchant delivers goods and corresponds to the order number. For a metering terminal in the middle transportation process of goods, the first object is a commodity which is received by the current courier and corresponds to the order number. For the metering terminal at the buyer side, the first object is the commodity corresponding to the order number received by the buyer, namely the commodity to be delivered.

Besides the system embodiment, the embodiment of the application also provides a corresponding data processing method. The data processing method provided by the embodiment of the present application is exemplarily described below from the perspective of a metering terminal and a server-side computing device, respectively.

The method is applicable to the metering terminal, and for the description of the metering terminal, reference may be made to the related contents in fig. 1a and fig. 1b, which are not described herein again. As shown in fig. 3, the method includes:

301. the moment of inertia of a first object on a bearing surface of the metering terminal is collected, and the first object is located at a designated position on the bearing surface.

302. And sending the rotational inertia of the first object and the object identification associated with the first object to the server-side computing equipment, so that the server-side computing equipment can check the first object by combining the rotational inertia of the second object associated with the object identification.

303. And receiving a check result of the first object returned by the server-side computing equipment, and outputting the check result, wherein the check result indicates whether the first object meets the specified requirement.

In the present embodiment, the carrying surface is used for carrying the first object to be measured, and the first object is located on a designated position of the carrying surface. The first object can be an article received by a current user, and can also be a commodity mailed by a sender through express delivery, such as articles per se such as mobile phones, computers, clothes, food and the like; but the present invention is not limited to this.

Optionally, a clamp can be arranged on the bearing surface, and the first object can be fixed at a designated position of the bearing surface through the clamp. For the description of the clamp, reference may be made to the related content of fig. 1a, which is not described herein again.

Optionally, the associated object identifier is different according to the difference of the first object. When the first object is a commodity purchased by a buyer or a commodity with a packing box or a packing bag, the object identifier associated with the first object may be, but is not limited to, an order number, a courier number, a model number of the commodity, and the like. In the embodiment of the present application, the commodity may be the commodity itself, or may include a commodity with a package. For the description of the first object, the second object and the designated object, reference may be made to the relevant contents of the application scenario 1 and the application scenario 2, which are not described herein again.

Further, in application scenario 1, the object identifier may be an order number corresponding to the buyer when placing an order. The user refers to a courier or a buyer who receives the goods corresponding to the order number in the current link. Namely, the first object is the commodity corresponding to the order number received by the current user. The second object may be a commodity sent by the merchant and corresponding to the order number, or a commodity received by a courier before the current user receives the commodity corresponding to the order number. The designated object is a commodity which is sent by the merchant and conforms to the order number.

In this embodiment, by using the characteristics of the rotational inertia, the mass of the object, and the mass distribution of the object, and combining with the metering terminal capable of acquiring the rotational inertia of the object on the bearing surface, the metering terminal and the server-side computing device are matched with each other, and whether the object meets the specified requirements, for example, whether the object is dropped or damaged, can be detected according to the rotational inertia of the object, which is beneficial to improving the accuracy of detection.

Further, since the moment of inertia is not only related to the mass of the object, but also related to the mass distribution thereof, in this embodiment, whether the object is dropped or damaged is detected according to the moment of inertia of the object, and it is possible to detect whether the object is dropped or damaged as a whole, and also detect whether the internal components thereof are dropped or damaged, thereby further improving the accuracy of detection.

In an optional embodiment, to ensure that the placement state of the first object on the bearing surface 11 is the same as the placement state of the second object at the moment of inertia when the bearing surface is collected, before step 301, the metering terminal further sends an information request to the server-side computing device, where the information request carries the object identifier, so that the server-side computing device returns the placement state information of the second object associated with the object identifier at the moment of collected moment of inertia; and then, the metering terminal receives the placing state information of the second object returned by the server-side computing equipment and outputs the placing state information of the second object, so that the user can place the first object on the bearing surface at the specified position according to the same placing state as the second object. Therefore, the measurement error of the rotational inertia of the first object and the second object caused by different placing states of the first object and the second object on the corresponding bearing surfaces can be reduced, and the accuracy of the subsequent verification of the first object based on the rotational inertia of the first object and the second object is improved.

Optionally, the placing state information of the second object when the rotational inertia is collected may be a measurement image of the second object on the corresponding bearing surface, which is shot by a camera on the metering terminal when the rotational inertia is collected, where the measurement image includes: and when the rotational inertia of the second object is acquired, the placing state of the second object on the corresponding bearing surface is acquired. Accordingly, the metering terminal may receive the measurement image of the second object returned by the server-side computing device and display the measurement image of the second object on its screen. This allows the user to place the first object on the bearing surface at a designated position in accordance with the placement in the measurement image of the second object.

Or an audio component is arranged on the metering terminal. Accordingly, the metering terminal can receive the placing state information of the second object returned by the server-side computing device, and the placing state information of the second object is played through the audio component.

Optionally, the metering terminal further comprises a camera. Correspondingly, the data processing method in fig. 3 further includes: if the first object on the bearing surface is detected to exist, the camera can be used for shooting a measurement image of the first object, and the measurement image of the first object is sent to the server-side computing equipment. The measurement image of the first object comprises the placing state of the first object on the bearing surface when the rotational inertia of the first object is acquired. Therefore, when the user in the next link measures the rotational inertia of the object received by the user, the measurement image of the first object uploaded in the link can be requested from the server-side computing device. For a description of detecting whether the first object exists on the carrying surface, reference may be made to the related description in fig. 1a, which is not repeated herein.

Further, the bearing surface may be a transparent bearing surface. The camera is arranged at the bottom of the transparent bearing surface.

Further, the metering terminal further comprises at least one of a screen and an audio component. Accordingly, in step 303, the metering terminal may display the verification result on its screen. Or the metering terminal plays the verification result through the audio component thereof. Or, the metering terminal can display the verification result on the screen thereof and play the verification result through the audio component thereof.

In an alternative embodiment, the metering terminal further comprises a rotating shaft and a force application unit for applying a force of a specified torque to the rotating shaft. The rotating shaft is arranged between the bearing surface and the control platform of the metering terminal. The rotating shaft can drive the bearing surface to rotate when the force application unit applies a rotating force with a specified moment to the rotating shaft. Based on this, an alternative implementation of step 301 is: under the condition that the first object is positioned on the bearing surface, applying a rotating force of a specified moment to a rotating shaft of the metering terminal so as to enable the rotating shaft to drive the bearing surface to rotate; collecting at least one angular velocity of the bearing surface in the rotation process of the bearing surface; and calculating the moment of inertia of the first object based on the at least one angular velocity and the specified moment.

In this embodiment, the user may manually control the force application unit to apply the rotational force of the designated torque to the rotating shaft, or may automatically apply the rotational force of the designated torque to the rotating shaft by controlling the force application unit.

When the metering terminal is implemented in a manner that the force application unit is manually controlled by a user to apply a rotating force of a designated torque to the rotating shaft, the force application unit includes a first driving member. Alternatively, the first driving member may be a spring, a pulley, or the like, but is not limited thereto. Based on this, a force of a specified moment is applied to the rotating shaft of the metering terminal, so that the rotating shaft drives the bearing surface to rotate, and an optional implementation manner is as follows: and responding to the rotation operation of a user on the first driving part on the metering terminal, and applying a rotating force to the rotating shaft by the first driving part so that the rotating shaft drives the bearing surface to rotate. Wherein, the number of rotations of user to first driving piece corresponds with the size of appointed moment. When the first driving piece is the clockwork spring, the designated moment is the moment generated when the clockwork spring is rotated by the user through the rotation control piece to enable the clockwork spring to be full-wound. Namely, when the user rotates the clockwork spring by utilizing the rotation control piece to enable the clockwork spring to be full, the number of turns of the clockwork spring corresponds to the designated moment.

Further, when the metering terminal is implemented in a form that a rotational force of a designated torque is automatically applied to the rotation shaft by controlling the force application unit, the force application unit includes a second driving member. Alternatively, the second driving member may be a motor, a motor driver, or the like. Based on this, another optional implementation manner of applying a force of a specified moment to the rotating shaft of the metering terminal to make the rotating shaft drive the bearing surface to rotate is as follows: if the first object is detected on the bearing surface, a rotating force is applied to the rotating shaft through the second driving piece on the metering terminal, so that the rotating shaft drives the bearing surface to rotate. When the second driving part is a motor, the working parameters of the second driving part and the rotating radius of the bearing surface during rotation correspond to the specified torque. Further, the operating parameters of the second drive member include: the operating power, the rotational speed, etc. of the motor, but are not limited thereto. The method specifically comprises the following steps: the command torque is equal to the rotational force applied by the second driving member to the shaft multiplied by the radius of rotation of the load-bearing surface as it rotates.

In another alternative embodiment, an angular velocity sensor is provided on the metering terminal. During rotation of the bearing surface, the angular velocity sensor may acquire at least one angular velocity of the bearing surface. Optionally, during the rotation of the bearing surface, the angular velocity sensor may sample the angular velocity of the bearing surface at a set sampling rate for a specified time period to obtain at least one angular velocity. For the description of the designated time period, reference may be made to the related description in fig. 1a, which is not repeated herein.

Accordingly, the moment of inertia of the first object may be calculated based on the at least one acceleration collected by the angular velocity sensor and the specified moment.

Further, the bearing surface can rotate on a horizontal plane, and can also rotate on a horizontal plane and a vertical plane simultaneously, namely, the bearing surface rotates in a spiral mode. Accordingly, when the bearing surface rotates in a spiral manner, the angular velocity sensor can collect the angular velocity of the bearing surface on the horizontal plane and the angular velocity of the bearing surface on the vertical plane in a specified time period according to a set sampling rate.

Accordingly, an optional implementation of calculating the moment of inertia of the first object according to the at least one acceleration acquired by the angular velocity sensor and the specified moment is as follows: performing linear regression processing on at least one angular velocity acquired by the angular velocity sensor to obtain a function relation between the angular velocity of the bearing surface and time; determining the angular acceleration of the bearing surface in the rotation process based on the functional relation between the angular speed of the bearing surface and time; and carrying out numerical operation on the angular acceleration and the appointed moment of the bearing surface in the rotating process to obtain the moment of inertia of the first object. The specific implementation mode is as follows: and dividing the designated moment by the angular acceleration of the bearing surface in the rotating process to obtain the moment of inertia of the first object. It is worth noting that the calculated moment of inertia of the first object is the moment of inertia of the first object on one plane. When the bearing surface rotates spirally, the angular acceleration of the bearing surface on the horizontal plane and the angular acceleration of the bearing surface on the vertical plane can be respectively utilized, and the respective corresponding specified moments are respectively utilized to calculate the moment of inertia of the first object on the horizontal plane and the vertical plane.

Accordingly, the present application also provides a computer-readable storage medium storing computer instructions, wherein the computer instructions, when executed by one or more processors, cause the one or more processors to perform the steps of the method shown in fig. 3 and the related embodiments thereof.

Further, since the moment of inertia is not only related to the mass of the object to be measured, but also related to the mass distribution thereof, the server-side computing device can detect whether the object is entirely wrapped or damaged, and can also detect whether the internal components thereof are wrapped or damaged, which is helpful to further improve the accuracy of detection.

In an alternative embodiment, the metrology terminal acquires the moments of inertia of the first object in multiple planes, and based on this, an alternative implementation of step 403 is: calculating the root mean square error of the moments of inertia of the first object and the second object on a plurality of planes; and comparing and calculating whether the root mean square error is greater than a set error threshold value; and if the comparison result is yes, namely the calculated root mean square error is larger than the set error threshold, determining that the first object does not meet the specified requirement, namely the verification result is that the first object does not meet the specified requirement. Correspondingly, if the calculated root mean square error is smaller than or equal to the set error threshold, the first object is determined to meet the specified requirement, namely the verification result is that the first object meets the specified requirement. The error threshold value can be flexibly set according to the actual requirement on the verification precision, and is not limited here.

Correspondingly, if the difference value of the moment of inertia of the first object and the second object on all the planes is larger than the error threshold value on the corresponding plane, the first object is determined to meet the specified requirement, namely the first object meets the specified requirement as a verification result.

In a further optional embodiment, based on the above fig. 1a, before the metering terminal acquires the rotational inertia of the first object, the metering terminal sends an information request to the server-side computing device, and accordingly, in this embodiment, before step 401, the server-side computing device further receives the information request, and according to the object identifier in the information request, acquires the placement state information when the rotational inertia of the second object associated with the object identifier is acquired.

Wherein the measurement image of the first object includes: when the moment of inertia of the first object is collected, the placing state of the first object on the bearing surface is obtained. Accordingly, in this embodiment, the server computing device also receives a measurement image of the first object. Therefore, when the user in the next link measures the rotational inertia of the object received by the user, the measurement image of the first object uploaded in the link can be requested from the server-side computing device.

Accordingly, the present application also provides a computer-readable storage medium storing computer instructions, wherein the computer instructions, when executed by one or more processors, cause the one or more processors to perform the steps of the method shown in fig. 4a and the related embodiments thereof.
