[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] At present, in the inspection and sorting system, the parcel needs to enter the sorting line after the parcel is scanned by the code scanning module to obtain the parcel information. After the parcel is weighed by the weighing module to obtain the weight information, the inspection and sorting system needs to automatically associate the weight information with the corresponding parcel. The parcel then enters the X-ray machine. When the X-ray machine scans and generates an X-ray image, the inspection and sorting system needs to automatically associate the X-ray image with the corresponding parcel and conduct an intelligent review of the X-ray image. If the intelligent review finds that the parcel contains prohibited items, the inspection and sorting system will automatically move the parcel to the inspection area.

[0027] However, the prior art requires that the package be labeled in advance by a labeling mechanism, and a code scanning mechanism be installed at the weighing module, X-ray machine, etc. When the package arrives at the weighing module, X-ray machine, the package is identified by scanning the code and the associated data is obtained, so that the package information arriving at the weighing module, X-ray machine can be determined. Therefore, the prior art requires the installation of an additional code scanning mechanism for code scanning, which is costly and has a low fault tolerance rate.

[0028] Based on this, a control method, device and electronic device for an inspection and sorting system provided by an embodiment of the present invention specifically provides a method for determining package information by inferring based on package order, position, and speed information. It only requires the installation of photoelectric sensors at key positions. The photoelectric sensors can detect the sequence of packages on the conveyor belt and the position of packages on the conveyor belt. There is no need to install an additional scanning mechanism for scanning, which has the advantages of low cost and high fault tolerance.

[0029] To facilitate understanding of this embodiment, a control method for an inspection and sorting system disclosed in an embodiment of the present invention is first introduced in detail.

[0030] Embodiment 1:

[0031] An embodiment of the present invention provides a control method for an inspection and sorting system. The inspection and sorting system is provided with a plurality of modules, and corresponding photoelectric sensors are provided on the plurality of modules of a conveyor belt of the inspection and sorting system.

[0032] The inspection and sorting system in this embodiment can be provided with multiple modules, and corresponding photoelectric sensors can be provided in multiple modules of the conveyor belt of the inspection and sorting system in this embodiment. It should be noted here that in this embodiment, photoelectric sensors can be provided before, after or in the module as needed, and corresponding photoelectric sensors are not necessarily provided in all modules in this embodiment. In this embodiment, corresponding photoelectric sensors can be provided in appropriate positions of appropriate modules as needed.

[0033] Based on the above description, see Figure 1 The flowchart of a control method of an inspection and sorting system is shown, and the control method of the inspection and sorting system comprises the following steps:

[0034] Step S102, after the parcel passes through each photoelectric sensor on the conveyor belt of the inspection and sorting system, the parcel is written into the queue corresponding to each photoelectric sensor; wherein each photoelectric sensor is provided with a corresponding queue.

[0035] In this embodiment, it is not necessary to install an additional code scanning mechanism in each module for code scanning, and only photoelectric sensors need to be installed at key positions. Each photoelectric sensor can write the packages passing through the photoelectric sensor into the queue of the photoelectric sensor in turn.

[0036] For example, if packages 1, 2, 3, ... n pass through photoelectric sensor 1 in sequence, the queue of photoelectric sensor 1 can be recorded as 1, 2, 3, ... n[1]. If packages 1, 2, 3, ... m pass through photoelectric sensor 3 in sequence, the queue of photoelectric sensor 1 can be recorded as 1, 2, 3, ... m[3]. The numbers in brackets "[]" represent the number of the photoelectric sensor or queue, which is used to distinguish the queues of different photoelectric sensors.

[0037] Step S104, determining the information of the package based on the queues corresponding to the various photoelectric sensors; wherein the information of the package includes: the sequence of the packages on the conveyor belt and the position of the packages on the conveyor belt.

[0038] In this embodiment, based on the queues corresponding to the various photoelectric sensors, the order of the packages on the conveyor belt and the positions of the packages on the conveyor belt and other information can be determined.

[0039] In some embodiments, the last queue in which a package exists can be determined to be the first target queue, and the position of the package on the conveyor belt is behind the photoelectric sensor corresponding to the first target queue.

[0040] For package X, if you want to determine the position of package X on the conveyor belt, you can first determine that the last queue with package X is the first target queue. For example, the queues with package X are the queues corresponding to photoelectric sensors 1, 2, and 3. Then, the last queue with package X is the queue corresponding to photoelectric sensor 3, that is, the first target queue is the queue corresponding to photoelectric sensor 3.

[0041] After determining that there is the last queue for package X, it can be determined that the position of the package on the conveyor belt is behind the photoelectric sensor corresponding to the first target queue. That is, if the last queue for package X is the queue corresponding to photoelectric sensor 3, the position of package X on the conveyor belt is behind photoelectric sensor 3.

[0042] In some embodiments, a second target queue in which packages exist can be determined from multiple queues, and the order of the packages on the conveyor belt can be determined based on the order of the packages in the second target queue.

[0043] For package Y, if you want to determine the order of package Y on the conveyor belt, you can first determine the second target queue where package Y exists. It should be noted here that generally the order of packages on the conveyor belt is fixed. Therefore, in this embodiment, it is not necessary to determine the last queue where package Y exists. It is only necessary to determine any queue where package Y exists as the second target queue.

[0044] For example, the queues containing package Y are queues corresponding to photoelectric sensors 1, 2, 3, and 4. Then, the second target queue containing package Y can be a queue corresponding to any one of photoelectric sensors 1, 2, 3, and 4.

[0045] For example, if the second target queue where package Y exists is the queue corresponding to photoelectric sensor 2, the order of package Y on the conveyor belt can be determined according to the order of packages in the queue corresponding to photoelectric sensor 2. For example, if the queues corresponding to photoelectric sensor 2 are 1, 2, 3...X, Y, Z...[2], then the order of package Y on the conveyor belt is between X and Z.

[0046] Therefore, in this embodiment, the order of the packages on the conveyor belt and the position of the packages on the conveyor belt can be detected by a photoelectric sensor, and there is no need to install an additional scanning mechanism for scanning the code, which has the advantages of low cost and high fault tolerance.

[0047] The embodiment of the present invention provides a control method for an inspection and sorting system, wherein after a package passes through each photoelectric sensor on a conveyor belt of the inspection and sorting system, the package is written into a queue corresponding to each photoelectric sensor; wherein each photoelectric sensor is provided with a corresponding queue; and information about the package is determined based on the queue corresponding to each photoelectric sensor; wherein the information about the package includes: the sequence of the packages on the conveyor belt and the position of the packages on the conveyor belt. In this method, the sequence of the packages on the conveyor belt and the position of the packages on the conveyor belt can be detected by photoelectric sensors, and there is no need to install an additional code scanning mechanism for code scanning, which has the advantages of low cost and high fault tolerance.

[0048] Embodiment 2:

[0049] This embodiment provides another control method for the inspection and sorting system, which is implemented on the basis of the above embodiment. Figure 2 A schematic diagram of an inspection and sorting system is shown, in which a conveyor belt is provided with a code scanning module, a weighing module, an X-ray machine module and a transplanting module in sequence; a first photoelectric sensor is provided in the weighing module, a second photoelectric sensor is provided behind the X-ray machine module, and a third photoelectric sensor is provided in front of the transplanting module.

[0050] like Figure 2 As shown, in this embodiment, photoelectric sensors can be installed at key positions of each conveyor belt, and the photoelectric sensors can detect package arrival and departure signals.

[0051] Based on the above description, see Figure 3 A flow chart of another control method of an inspection and sorting system is shown, and the control method of the inspection and sorting system comprises the following steps:

[0052] Step S302: After the parcel passes through the barcode scanning module on the conveyor belt of the inspection and sorting system, the scanning result of the barcode scanning module is associated with the parcel, and the parcel is written into the first queue.

[0053] like Figure 2 As shown, after multiple packages a, b...n pass through the barcode scanning module, they can be written into the first queue in sequence: a, b...n[1]. The numbers in the brackets "[]" in this embodiment represent the queue numbers, which will not be described in detail later.

[0054] Step S304, after the package passes through the first photoelectric sensor on the conveyor belt of the inspection and sorting system, the weighing result of the weighing module is associated with the package, and the package is written into the second queue corresponding to the first photoelectric sensor.

[0055] like Figure 2 As shown, when the first photoelectric sensor detects the arrival of a package, the package can be taken out from the head of the first photoelectric sensor queue, and the weighing result of the weighing module is obtained and associated with the package, and then put into the second queue. When packages a, b...n pass through the first photoelectric sensor in sequence, the algorithm can ensure that the second queue is: a, b...n[2].

[0056] Step S306, after the parcel passes through the second photoelectric sensor on the conveyor belt of the inspection and sorting system, the X-ray image of the X-ray machine module is associated with the parcel, and the parcel is written into the third queue corresponding to the second photoelectric sensor.

[0057] like Figure 2 As shown, when the second photoelectric sensor detects the arrival of a package, the package can be taken out from the head of the second photoelectric sensor queue, and the X-ray image of the X-ray machine module is obtained and associated with the package, and then put into the third queue. When packages a, b...n pass through the second photoelectric sensor in sequence, the algorithm can ensure that the third queue is: a, b...n[3].

[0058] Step S308, after the package passes through the third photoelectric sensor on the conveyor belt of the inspection and sorting system, it is determined whether the package is abnormal based on the X-ray image of the package, and the package is written into the fourth queue corresponding to the third photoelectric sensor.

[0059] like Figure 2 As shown, when the third photoelectric sensor detects the arrival of a package, it determines whether the X-ray image contains prohibited items based on the X-ray image information associated with the package. If the X-ray image contains prohibited items, the inspection and sorting system can control the transfer module to transfer the package to the inspection area. If the X-ray image does not contain prohibited items, the inspection and sorting system can release the package. When packages a, b...n pass through the third photoelectric sensor in sequence, the algorithm can ensure that the fourth queue is: a, b...n[4].

[0060] Step S310: Determine the information of the package based on the queues corresponding to the respective optoelectronic sensors; wherein, the information of the package includes: the order of the packages on the conveyor belt and the positions of the packages on the conveyor belt.

[0061] In this embodiment, the specific manner of determining the information of the package based on the queues corresponding to the respective optoelectronic sensors can refer to the relevant description of step S104 in the foregoing embodiment, and this embodiment will not elaborate further. Additionally, it should be noted that fault tolerance processing can also be performed in this embodiment.

[0062] In some embodiments, the running speed of the conveyor belt can also be obtained; determine the time when the package passes through each optoelectronic sensor on the conveyor belt; and determine whether there is an abnormality of the package based on the running speed and the time.

[0063] In this embodiment, the running speed v of the conveyor belt can be obtained through a PLC (Programmable Logic Controller), and each optoelectronic sensor can record the time when each package passes through this optoelectronic sensor; determine whether there is an abnormality of the package based on the running speed v and the above time.

[0064] In some embodiments, after the package passes through the current optoelectronic sensor, determine the predicted time for the package to pass through the next optoelectronic sensor based on the running speed and the time when the package passes through the current optoelectronic sensor; after the package passes through the next optoelectronic sensor, determine the target time for the package to pass through the next optoelectronic sensor; if the target time is greater than the sum of the predicted time and the preset redundancy time, determine that there is an abnormality of taking away in the middle; control the inspection and sorting system to perform an alarm process; if the target time is less than the difference between the predicted time and the redundancy time, determine that there is an abnormality of putting in a package; control the inspection and sorting system to perform an alarm process; if the target time is less than or equal to the sum of the predicted time and the redundancy time, and the target time is greater than or equal to the difference between the predicted time and the redundancy time, determine that there is no abnormality of taking away or putting in a package in the middle.

[0065] For example, when package a passes through the No. 1 optoelectronic sensor, based on the running speed v of the conveyor belt, calculate the predicted time t1 for reaching the No. 2 optoelectronic sensor after the No. 1 optoelectronic sensor. Determine the time (i.e., the target time) for the package to pass through the No. 2 optoelectronic sensor as t2, and the redundancy time as s.

[0066] If t1 - s < t2 < t1 + s, then determine that there is no abnormality of taking away or putting in a package in the middle. If t1 - s ≥ t2, then determine that there is an abnormality of putting in a package, indicating that the package is taken away in the middle, and the line body needs to be paused for an alarm prompt. If t2 ≥ t1 + s, then determine that there is an abnormality of taking away in the middle, indicating that a new package is put in the middle, and the line body needs to be paused for an alarm prompt.

[0067] In some embodiments, if the difference in time between adjacent packages passing through the photoelectric sensor is smaller than a preset threshold, it is determined that there is an abnormality of package adhesion; the inspection and sorting system is controlled to perform package pulling processing; if the difference is greater than or equal to the threshold, it is determined that there is no abnormality of package adhesion.

[0068] Determine the difference △t between the time when two adjacent packages trigger a photoelectric sensor. If △t < the preset threshold f (threshold f can be set to 1s), it is determined that there is an abnormality of package adhesion, indicating that the two packages are too close to each other and need to be stopped in the next section of the conveyor belt to pull the package. If △t ≥ threshold f, it is determined that there is no abnormality of package adhesion.

[0069] The existing technology requires labeling the package through a labeling mechanism and installing a code scanning mechanism at a key position to determine the package information arriving at the X-ray machine.

[0070] Compared with the above-mentioned prior art, the above-mentioned method provided by the embodiment of the present invention can determine the information of the packages passing through the key module by calculating the order in which the packages are placed, the location where the packages arrive, and the running speed information of the conveyor belt. The time when the package arrives at the next photoelectric sensor is calculated by the running speed of the conveyor belt. If the time is abnormal, it means that the package is taken away or placed in the middle, and an alarm is processed. When it is found that the time t when adjacent packages trigger the same photoelectric sensor successively is less than the preset threshold f, it can be determined that the two packages are too close to each other and stick together, and it is necessary to pause the next section of the conveyor belt to pull the package.

[0071] In summary, the above method provided by the embodiment of the present invention can determine the parcel information by calculating the order in which the parcels are put in, the parcel arrival position, and the running speed information of the conveyor belt. The fault-tolerant processing method can handle the situations of taking away or putting in midway, and the parcel sticking. Compared with the prior art, it has the characteristics of low cost and high fault tolerance.
