Fig. 1 is a schematic structural diagram of a package inspection platform according to an embodiment of the present invention. As shown in fig. 1, the structure of the package inspection platform includes: a conveyor 13, a detection member 12 and a package detection device 11. The conveying device 13 is used for conveying the packages to be sorted, and may be a conveyor belt. The speed at which the conveyor 13 conveys the packages may be adaptively adjusted according to the switching of the package detection mode. The detecting component 12 is used for detecting or not detecting the current to-be-detected packages conveyed on the conveying device 13 according to the detection rules in the current package detection mode. And the detecting component detecting the current parcel to be detected sends the parcel parameters to the parcel detecting device, wherein the parcel parameters to be detected are different in different parcel detecting modes. In particular, the detection means 12 may comprise a weighing device, a code reading camera, a volume measuring device, etc. Wherein the weighing device is adapted to measure or not measure the weight of the package transferred from the transfer means 13 to the weighing device according to the detection rules in the current package detection mode; the code reading camera is used for shooting or not shooting the bar code image and the identification bar code of the package conveyed on the conveying device 13 according to the detection rule in the current package detection mode; the volume measuring device is used for measuring or not measuring the volume of the packages conveyed on the conveying device according to the detection rule in the current package detection mode. The parcel detection apparatus 11 is configured to execute the parcel detection method according to the embodiment of the present invention, and is configured to control the detection component 12 to switch to a corresponding parcel detection mode according to the detection mode switching instruction, and acquire, in the switched parcel detection mode, a parcel parameter sent by the detection component that has performed parcel detection; and the package detection device determines that the package parameters needing to be acquired in the current detection mode are all received according to the acquired package parameters, and detects the next package in the current package detection mode.
In the package inspection platform shown in fig. 1, the package inspection device 11 is a master device, which may be a computer, for example. In practical implementation, the package detection device 11 may be connected to each of the detection component 12 and the conveying device 13, respectively, to control the detection component 12 and the conveying device 13 to switch the detection mode and control the detection component 12 to detect the package in the switched package detection mode. In one example, the package detection device 11 may be communicatively coupled to the conveyor 13, the detection component 12. In another possible design, as shown in FIG. 1, the package inspection platform may also include a control component 14. The control unit 14 is communicatively connected to the package inspection device 11. The control means 14 may be connected to the conveying means 13, part or all of the detecting means 12, in addition to the package detecting means 11. The control unit 14 and the transmission device 13 may be electrically connected. When the transfer device 13 is connected to the partial detection member 12, it may be electrically connected. Other detection members 12 not connected to the conveyor 13 may be communicatively connected to the package detection device 11. In this example, when the control section 14 receives the detection mode switching instruction transmitted by the package detection device 11, the control section 14 may control the conveying device 13 to convey the package according to the package conveying rule of the package detection mode after switching, according to the detection mode switching instruction. In particular, the control means 14 can control the conveying device 13 to convey the packages at a conveying speed matching the current detection mode. Further, when the control part 14 is connected to part or all of the detecting parts 12, the control part 14 controls the detecting part 12 connected thereto to perform switching of the detection mode according to a detection mode switching instruction sent from the package detecting device 11, and controls the detecting part 12 to detect the package in the switched detection mode. In one example, the control unit 14 may be connected to a weighing device, a volume measuring device, and a code reading camera, and when the control unit 14 receives the detection mode switching instruction, the control unit controls the weighing device, the volume measuring device, and the code reading camera connected thereto to weigh, measure the volume, and read the barcode of the parcel according to the detection rule after the mode switching. Specifically, the control unit 14 may be a Programmable Logic Controller (PLC). Alternatively, the control unit 14 may be provided separately or integrated in one of the detection units 12. For example, the control unit 14 is integrated in the weighing device. It will be appreciated that when the control unit 14 is integrated in a particular detection unit 12, the control unit 14 may perform the functions of the detection unit 12 in addition to the control commands sent by the package detection device 11. In one example, when the control part 14 is integrated in the weighing apparatus, the control part 14 may control the weighing apparatus to switch the package detection mode and perform the package weighing function in the switched detection mode.
Further, the control part 14 may also send the package parameters detected by the detection part to which it is connected to the package detection device 11 after switching the detection part to which it is connected to the corresponding package detection mode. After sending the package parameters to the package detection device 11, the control component 14 sends a data solicitation instruction to the package detection device 11, where the data solicitation instruction is used to obtain a feedback response from the package detection device 11, and the feedback response is used to indicate whether each parameter of the package to be currently detected is effectively obtained. If the control component 14 receives a feedback response that each package parameter of the current package to be detected sent by the package detection device 11 has been effectively obtained, the control component 14 controls the conveying device 13 to convey the next package to be detected according to the package conveying rule of the current package detection mode.
Fig. 2 is a schematic structural diagram of another package inspection platform according to an embodiment of the present invention. As shown in fig. 2, the package inspection platform comprises: a conveyor belt 21; a weighing device 22 is provided below the conveyor belt 21. As the parcels are conveyed by the conveyor belt 21 to the weighing device 22, the weighing device 22 weighs the parcels thereon. Further, a code reading camera 23 is arranged above the weighing device 22, and the code reading camera 23 shoots the barcode image of the package conveyed to the weighing device 22; in addition, a volume measuring device 24 may be arranged above the weighing device 22, and the volume measuring device 24 may be a line structured light stereo camera. The line structured light stereo camera may be used to measure the volume of the package delivered to the weighing apparatus 22. In the embodiment of the present invention, the barcode image captured by the code reading camera 23, the package weight measured by the weighing device 22, and the package volume measured by the volume measuring device 24 may all be sent to the package detection device, so as to summarize and integrate the package parameters sent by each detection component through the package detection device. In the package inspection platform shown in fig. 2, control means may also be included, which are integrated in the weighing device 22. In one example, the control component may be integrated with the weighing device 22 and the conveyor belt 21 into one dynamic scale device. The dynamic scale device is in communication connection with the package detection device. Specifically, the control part in the dynamic scale device is in communication connection with the package detection device, and the control part in the dynamic scale device is also electrically connected with the weighing device and the conveyor belt. Other detection components in the package inspection platform, such as a code reading camera 23, a volume measuring device 24, are communicatively coupled to the package inspection device. In this example, the parcel detection apparatus is used for controlling the detection components connected with the parcel detection apparatus, such as the code reading camera 23 and the volume measurement device 24, to detect parcels according to the detection rules in the corresponding detection modes according to the detection mode switching instruction; the parcel detection apparatus is further configured to send a detection mode switching instruction to the control unit, so as to control the conveyor belt 21 to convey the parcel according to the parcel conveying rule of the switched parcel detection mode through the control unit, and control the weighing device 22 to process the parcel according to the detection rule of the switched parcel detection mode.
It is to be understood that fig. 1 and fig. 2 are only exemplary illustrations of the package detection platform provided in the embodiment of the present invention, and do not constitute a specific limitation to the package shooting system. In other embodiments of the present invention, the package inspection platform may include more or less devices than those shown in the figures, for example, the package inspection platform further includes a routing device, a bracket for setting the code reading camera and the line structured light stereo camera, and the like, which are not listed in this embodiment.
For convenience of understanding, the following embodiments of the present invention will specifically describe a package detection method provided by the embodiments of the present invention by taking the package detection platform shown in fig. 1 and fig. 2 as an example, and combining the accompanying drawings and application scenarios. More specifically, the following main execution body of the package detection method is a package detection device in a package detection platform.
Fig. 3 is a flowchart of a package detection method according to an embodiment of the present invention. As shown in fig. 3, the processing steps of the method include:
301, the parcel detection apparatus receives a detection mode switch instruction.
In the embodiment of the invention, the parcel detection platform supports multiple parcel detection modes, and the multiple detection modes can be switched. Specifically, the parcel detection platform implements the switching of parcel detection modes based on a detection mode switching instruction. The package detection device may be configured to receive a detection mode switch instruction.
In the embodiment of the present invention, the detection mode switching instruction may be triggered based on an operation of a user. Optionally, the package detection device displays a package detection mode switching interface, the package detection mode switching interface includes a detection mode switching function key, and the user sends a detection mode switching instruction to the package detection device by triggering the detection mode switching function key.
In addition to the detection mode switching instruction being triggered by the user's operation, the package detection apparatus may also automatically trigger the detection mode switching instruction. In one possible design, the package detection device may determine a package detection mode and a mode switching time according to the amount of packages to be detected; and when the determined mode switching time is reached, the package detection device receives a detection mode switching instruction which is automatically triggered by the package detection device.
Determining, by the package detection device, a package detection mode and mode switching time according to the package amount to be detected may include: the method comprises the steps that a parcel detection device obtains the parcel volume to be detected and obtains the parcel processing speed in each parcel detection mode; predicting the package processing completion time in each package detection mode according to the package amount to be detected and the package processing speed in each package detection mode; and determining a parcel detection mode and mode switching time according to the predicted parcel processing completion time.
For example, the package inspection apparatus supports a first inspection mode, a second inspection mode and a third inspection mode in which the processing speed of the package is v1、v2、v3(ii) a If the parcel volume to be detected is M, the time required by the first detection mode, the second detection mode and the third detection mode for processing the parcels can be predicted to be M/v respectively1、M/v2、M/v3. In one possible design, the least used package detection mode may be selected to detect M packages. In another possible design, multiple detection modes may be combined, for example, a portion of the packages in the M may be selected to be detected according to a first detection mode, a portion of the packages may be detected according to a second detection mode, and the remaining portion may be detected according to a third detection mode. The detection modes may be performed sequentially, for example, after the first detection mode is performed, the second detection mode is performed, and finally the third detection mode is performed. Optionally, the detection modes may be alternatively executed, so as to improve the package detection efficiency and ensure the integrity of the package detection information as much as possible.
302, the package inspection device switches the inspection component of the package inspection platform to the corresponding package inspection mode according to the inspection mode switching instruction.
And after receiving a detection mode switching instruction triggered by a user or triggered by the user, the package detection device switches the detection part of the package detection platform to a corresponding package detection mode. Wherein, parcel detection device switches the detection component to corresponding parcel detection mode, includes: the parcel detection apparatus determines a detection component whose operation state needs to be adjusted in the switched parcel detection mode. The working state needing to be adjusted may be, for example, switching from a detection state to no package detection, switching from no package detection to package detection at a certain frequency, or switching from a first detection frequency to a second detection frequency, and so on, which are not illustrated here. The parcel detection device sends a working state adjustment instruction to a detection component needing to adjust the working state or the parcel detection device sends a working state adjustment instruction to a detection component needing to adjust the working state through a control component. And after the detection part needing to adjust the working state receives the working state adjusting instruction, package detection is carried out according to the adjusting information in the working state adjusting instruction. And for the detection component which does not need to adjust the working state in the switched package detection mode, detecting the package according to the currently set detection rule. Specifically, the adjustment information may include a detection rule in the detection mode after switching or a detection rule identifier. For example, in the switched package detection mode, the frame rate at which the barcode camera captures the barcode image needs to be adjusted, and the detection rule included in the adjustment information may be the capture frame rate to which the barcode camera needs to be adjusted. Alternatively, when the code reading camera needs to switch to the first package detection mode, the adjustment information may include a detection rule identifier, for example, a first detection rule identifier. And after receiving the first detection rule identification, the code reading camera determines the shooting frame rate to be adjusted according to the first detection rule identification, and shoots the package bar code image according to the adjusted shooting frame rate.
Further, the parcel detection device sends operating condition adjustment instruction to the detection part that needs to adjust operating condition through control part, includes: when part of the detecting parts are connected with the parcel detecting device through the control part, the parcel detecting device sends a working state adjusting instruction to the detecting parts connected with the control part through the control part. For other detection components which are not connected with the control component and are connected with the package detection device, the package detection device directly sends the working state adjustment instruction.
In another possible design, when part of the detecting components are connected with the parcel detecting device through the control component, after the parcel detecting device receives the parcel detection mode switching instruction, the parcel detecting device also sends the parcel detection mode switching instruction to the control component, and after the control component receives the parcel detection mode switching instruction, the control component determines the switched parcel detection mode and the detecting component connected with the control component and needing to adjust the working state. The control component sends an operating state adjusting instruction to a detection component which is connected with the control component and needs to adjust the operating state. Further, the control means may also adjust the conveying speed of the conveying device after receiving the detection mode switching instruction, so that the conveying device conveys the package according to the package conveying rule matching with the current package detection mode.
Under different package detection modes, each detection component can detect or not detect the package according to different detection rules. Wherein the conveyor can convey packages at different conveying speeds in different package detection modes. For example, in a first detection mode, the conveyor belt conveys the packages at a first speed; and after the detection mode is switched from the first detection mode to the second detection mode, the conveyor belt conveys the packages according to the second speed, and the speed of the conveyor belt can be adjusted according to the type and the number of package parameters needing to be acquired in each mode. For the code reading camera, the code reading camera can shoot the bar code of the parcel in different parcel detection modes at different shooting frame rates. For example, in a first detection mode, a code reading camera shoots a package barcode according to a first frame rate; when the mode is switched to the second detection mode, the shooting frame rate of the code reading camera can be kept unchanged at the first frame rate, and can also be adjusted to the second frame rate according to the setting. For a weighing apparatus, it may perform the weighing function in different weighing states in different package detection modes. Wherein the weighing state comprises: not executing weighing function, wrapping one by one to execute weighing function, and every X1Each parcel performs a weighing function once every Y1The time performs a weighing function. In one example, in the first detection mode, the weighing apparatus may not perform a weighing function; in a second detection mode, the weighing equipment detects the weight of each parcel one by one; in thatIn a third detection mode, the weighing device selectively weighs the packages, e.g. every X by the weighing device1Each parcel performs a weighing function, or every Y1The time performs a weighing function. For a volume measuring device, it may perform a volume measuring function in different volume measuring states in different package detection modes. Wherein the volume measurement state may include: not performing volume measurement function, wrapping volume by volume, every X2Each parcel performs a volume measurement function once every Y2Time performs a volume measurement function. In one example, in a first detection mode, the volume measurement device may perform volume measurement functions on a parcel-by-parcel basis; in the second detection mode, the volume measurement device may not perform a volume measurement function; in a third detection mode, the volume measurement device may selectively measure the volume of the package, e.g., the volume measurement device may measure every X2Each parcel performs a volume measurement function, or every Y2Time performs a volume measurement function. It should be noted that, the arrangement of the detection component in each detection mode is only an example, and may be set as needed in specific implementation, and is not illustrated here.
303, the detecting component detects or does not detect the current parcel to be detected in the switched parcel detection mode.
In the embodiment of the invention, after the detection mode of the package is switched, each detection part detects or does not detect the current package to be detected conveyed on the conveying device according to the detection rule of the switched package detection mode. Wherein the detection component that detects the current package to be detected sends the package parameters to the package detection device. The package parameters to be detected are different in different package detection modes, which can be specifically indicated by different types of package parameters and/or different numbers of package parameters to be detected.
The package inspection device obtains from the inspection component package parameters of the package currently being inspected as detected in the current package inspection mode 304.
305, the package detection device determines whether all the package parameters that need to be acquired in the current package detection mode have been received. If both have been received, go to step 306; if the package inspection device determines that the package parameters acquired in the current package inspection mode are missing at least one item compared to the package parameters that need to be acquired in the current package inspection mode, step 307 is performed.
The package inspection device controls the inspection component to inspect the next package 306.
307, the package detection device sends a reacquisition instruction to the detection component corresponding to the missing parameter, so that the corresponding detection component detects the package to be detected again, and sends the detected parameter to the package detection device.
The parcel detection method of the embodiment of the invention supports different parcel detection modes, and parcel parameters needing to be detected in different parcel detection modes are different, so that the detection time for completing parcel detection in each detection mode is different, the parcel detection efficiency is different in different parcel detection modes, and meanwhile, parcel data obtained in different detection modes have different precision and integrity. In specific implementation, different package detection modes can be selected according to package detection scenes so as to meet the requirements of package detection efficiency and package data precision and integrity.
In an embodiment of the present invention, the package detection mode supported by the package detection apparatus may include: a code-reading mode, a code-reading weighing mode, a code-reading volume-measuring mode and a code-reading weight-measuring volume mode. Wherein the package parameters that need to be acquired in different package inspection modes are different. When detecting the package in the code-read-only mode, only the bar code information of the package needs to be acquired. Specifically, a barcode image of the package can be captured and acquired by a code reading camera and sent to a package detection device so that the package detection device can identify the barcode from the barcode image; in this mode, the weighing device and the volume measuring device do not perform the functions of weighing and measuring volume; and after determining that the bar code of the current parcel is detected, the parcel detection device continues the code reading operation of the next parcel. In this mode, only the parcel bar code needs to be acquired, the volume does not need to be measured again, and the parcel detection efficiency can be improved.

Fig. 4 is a flowchart of another parcel detection method according to an embodiment of the present invention. The package inspection platform applied by the method shown in fig. 4 comprises a package inspection device, a code reading camera, a volume measurement device and a dynamic scale device. Wherein, parcel detection device with read code camera, volume measurement communication connection. For a dynamic scale device, a controller is contained and is in communication connection with the package detection device, and the controller is also electrically connected with the weighing device and the conveyor belt. As shown in fig. 4, the processing steps of the method include:
401, after the package detection device is started, a Transmission Control Protocol (TCP) server is started to monitor and establish a connection with the control component after receiving a connection request from the control component.
402, the package inspection device displays an inspection mode selection window. The detection mode selection window enables a user to select a package detection mode. For example, a read-only code mode, a read code weighing mode, a read code volumetry mode, and a read code weighing volumetry mode may be included in the detection mode selection window. The user can select one mode from the read-only code mode, the code reading weighing mode, the code reading volume measuring mode and the code reading weighing volume measuring mode displayed on the detection mode selection window.
The package detection device receives a selection operation from the user 403. The package detection device triggers a detection mode switching instruction through the selection operation of a user. For example, if the user selects the code reading and weighing mode from the package detection mode selection window, a detection mode switching instruction for switching to the code reading and weighing mode is triggered in the package detection device.
The package detection means controls the switching of the package detection mode of the detection means according to the detection mode switching instruction 404. And the parcel detection device determines the switched parcel detection mode according to the detection mode switching instruction. The parcel detection device judges whether the working states of the code reading camera and the volume measurement equipment need to be adjusted or not according to the switched parcel detection mode, and if the working states need to be adjusted, the working state adjustment instruction is sent to the detection component (the code reading camera and/or the volume measurement equipment) which needs to be adjusted. Further, the parcel detection apparatus may further determine whether the operating states of the weighing device and the conveyor belt need to be adjusted, and if so, generate a corresponding operating state adjustment instruction and send the instruction to the weighing device and/or the conveyor belt through the control unit. In another possible design, as shown in fig. 4, the parcel detection apparatus sends a detection mode switching instruction to the control section, so that the control section judges whether the operating states of the conveyor belt and the weighing device need to be adjusted according to the detection mode switching instruction, and when it is determined that the operating states of the conveyor belt and/or the weighing device need to be adjusted, the control section generates an operating state adjusting instruction and sends the operating state adjusting instruction to the corresponding device. For the detection part which does not need to adjust the working state, the detection part can detect the packages according to the currently set detection rule. And after determining the detection rule required to be executed according to the received working state adjusting instruction, each detection part sends a detection mode switching success instruction to the package detection device. Wherein the weighing device and the conveyor belt send a detection mode switching success instruction through the control part. And the code reading camera and the volume measuring equipment directly send a detection mode switching success instruction to the package detection device.
The package detection means 405 determines whether or not the package detection mode of each detection means is successfully switched. Specifically, the package inspection device determines whether the inspection mode switching success instructions of the inspection parts whose operating states need to be adjusted in the current package inspection mode have been received. If the detection mode switching success instructions of all detection components needing to adjust the working state are received, determining that the package detection mode switching is successful; otherwise, determining that the switching of the parcel detection mode fails.
406, if the package detection mode switch is successful, the package detection device modifies the configuration file and initiates package detection. Specifically, the package detection device executes package detection according to the detection rules in the modified configuration file. If the package detection mode switch fails, a jump is made back to 402.
The package detection means performs detection of the package 407. And under the switched package detection mode, each detection part detects or does not detect the package according to the detection rule matched with the current detection mode. The detection component in which the package detection is performed sends the package parameters to the package detection device or the detection component sends the package parameters to the package detection device through the control component. After receiving the package parameters, the package detection device judges whether the package parameters needing to be detected in the current package detection mode are all received, and if the package parameters are all received, the package detection device detects the next package. If the package parameters acquired in the current package detection mode lack at least one package parameter compared with the package parameters required to be acquired in the current package detection mode, the package detection device sends a re-detection instruction to the corresponding detection component, or sends a re-detection instruction to the corresponding detection component through the control component, so as to reacquire the missing package detection parameters. The interaction flow between the package detection device and the control means is described below with reference to fig. 5 to 6.
Fig. 5(a) to 5(c) are flow charts of parcel detection in the read-only code mode according to an embodiment of the present invention. As shown in fig. 5(a), in the read-only code mode, the control component sends an initiation command to the package detection device after the package enters the measurement area, e.g., after the package is transferred to a weighing device. The package detection device sends an initial response to the control unit after receiving the initial command, so as to start the detection of the package entering the measurement area. In the code-read-only mode, the barcode image of the package is only captured by the code-read camera. After the code reading camera shoots the barcode image of the package, the barcode image is sent to the package detection device, and the package detection device identifies the package barcode from the barcode image. As shown in fig. 5(b), the parcel detection device detects the parcel barcode, and after the normal measurement of the parcel is completed, the parcel detection device sends a release instruction to the control component; and after receiving the releasing instruction, the control component transmits the package to a package sorting platform for next package sorting, and sends a normal ending instruction to the package detection device. And when the package detection is finished, the package entering the measurement area next time is detected continuously.
As shown in fig. 5(c), when the package detection device identifies the package barcode, if the package detection device does not receive the barcode image or does not identify a valid barcode from the barcode image, a detection stop instruction is issued to the control component, and at this time, the package can be taken down manually; and after receiving the detection stopping instruction, the control part resets each detection part, sends a reset ending instruction to the package detection device after the reset is finished, and the package detection device continues to detect the next package entering the measurement area after receiving the reset ending instruction.
Fig. 6(a) to 6(b) are flow charts of parcel detection in the code-reading weighing mode according to the embodiment of the present invention. In the code reading and weighing mode, the process of starting the package detection when the package enters the measurement area is not described in detail with reference to fig. 5 (a). Under the code reading weighing mode, a code reading camera shoots a bar code image of a parcel entering a measuring area, and a weighing device measures the weight of the corresponding parcel. And after the code reading camera shoots the barcode image of the package, the barcode image is sent to the package detection device. After the weighing device reads the weight of the package, the control component in the weighing device sends the read weight data of the package to the package detection device. After receiving the package weight data, the package detection device sends a weight response to the control component.
As shown in fig. 6(a), after receiving the weight response sent by the package detection device, the control component sends a data solicitation instruction to the package detection device, so as to obtain a feedback response indicating whether the package weight data and the package barcode are both valid from the package detection device; if the parcel weight data received by the parcel detection device and the identified parcel barcode are both valid, the control component is sent a data claim normal response after receiving a data claim instruction sent by the control component. After receiving the data request and normally responding, the control part determines that the bar code and the weight information of the current package are successfully acquired, and at the moment, the control part sends a normal detection ending instruction of the current package to the package detection device; and the package detection device sends a current package detection end response to the control component after receiving the current package detection normal end instruction. At this point, the package inspection is finished, and the inspection of the next package entering the measurement area is continued.
As shown in fig. 6(b), if the control component sends a data request command to the package detection device, and if the package barcode identified by the package detection device is abnormal, the package detection device sends a data request bar missing code response to the control component, and the package barcode can be manually taken down to be additionally recorded. And the control part resets each detection part, sends a reset ending instruction to the parcel detection device after the reset is finished, and the parcel detection device sends an ending response to the control part after receiving the reset ending instruction and continues to detect the next parcel entering the measurement area. If the parcel detection device receives the data request command, the parcel weight measurement is judged to be abnormal, and the parcel weight can be measured again through the control component.
In the code reading and volume measuring mode, the process of starting the package detection when the package enters the measuring area is not described in detail with reference to fig. 5 (a). In the code reading and volume measuring mode, a code reading camera shoots a bar code image of a package entering a measuring area, and volume measuring equipment measures the volume of the package. And after the code reading camera shoots the barcode image of the package, the barcode image is sent to the package detection device. After the volume measuring device reads the volume of the package, the volume data can be sent to the package detecting device through the control component or the volume measuring device directly sends the volume data to the package detecting device. In one example, the volume measurement device sends the volume data to the package detection apparatus via the control component. After receiving the package volume data, the package detection device sends a volume response to the control component. After receiving the volume response sent by the parcel detection device, the control component sends a data solicitation instruction to the parcel detection device so as to obtain effective feedback response of both the parcel volume data and the parcel bar code from the parcel detection device; if the parcel volume data received by the parcel detection device and the identified parcel barcode are both valid, the data claim normal response is sent to the control component after the data claim instruction sent by the control component is received. After receiving the data request and normally responding, the control part determines that the bar code and the volume information of the current package are successfully acquired, and at the moment, the control part sends a normal detection ending instruction of the current package to the package detection device; and the package detection device sends a current package detection end response to the control component after receiving the current package detection normal end instruction. At this point, the package inspection is finished, and the inspection of the next package entering the measurement area is continued.
Further, in the code reading weighing volume measuring mode, the volume of the detected parcel is increased on the basis of the code reading weighing mode, the specific interactive flow can refer to fig. 5(a) to 5(c) and fig. 6(a) to 6(b), and when the data of code reading, weight measuring and volume measuring are normal, the detection of the next parcel can be continued; if one or more of the code reading, the weight measuring and the volume measuring are abnormal, the re-measurement can be reset, and the specific process is not repeated.
