Description

Technical Field

[0001] The present application relates to the field of automatic control technology, and more particularly, to a multi-target detection method, device and electronic device based on a screening line. Background Art

[0002] In supermarket logistics transportation, a screening line of a suspension chain system is used to transport goods that are about to be packed and shipped out of the warehouse. The screening line consists of individual format chains. Under normal circumstances, there should be only one suspended package in each format chain to ensure that each package can be transported and distributed to the correct packing and shipping position. In actual situations, due to errors in the structure of the upper hanging track, low accuracy of sensor recognition, manual hanging, etc., there may be more than two packages in a format chain as a cell, which may lead to problems such as incorrect subsequent package distribution and jamming of distribution threads. When there is a multi-package problem where there are multiple packages in a format chain, it is necessary to quickly determine the location where the problem occurs in the production system in order to solve the problem in a timely manner and avoid continuous multi-package situations in subsequent processes. However, currently, the multi-package situation is generally only discovered manually when the package is transported to the packing and shipping personnel, and there is no fast and efficient way to detect the location of the multi-package.

[0055] In the following introduction, the terms "first" and "second" are only for the purpose of description and cannot be construed as indicating or implying relative importance. The following introduction provides multiple embodiments of the present application. Different embodiments can be replaced or combined. Therefore, the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing all other possible combinations of A, B, C, and D, although such embodiments may not be explicitly described in the following content.

[0056] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the functions and arrangements of the elements described without departing from the scope of the present application. Various processes or components may be appropriately omitted, substituted, or added to each example. For example, the methods described may be performed in a different order than the order described, and various steps may be added, omitted, or combined. In addition, the features described for some examples may be combined into other examples.

[0057] See Figure 1 , Figure 1 is a schematic flow chart of a multi-target detection method based on a screening line provided by an embodiment of the present application. In the embodiment of the present application, the method includes:

[0058] S101. Continuously obtain the detection data uploaded by each detection terminal preset on the screening line, and parse the detection data to obtain detection result information.

[0059] The execution subject of the present application may be a cloud server.

[0060] In the embodiment of the present application, multiple detection terminals are pre-set at different positions on the screening line for conveying hanging packages to be shipped. The cloud server will continuously obtain the detection data uploaded by each detection terminal, and parse the obtained detection data to generate detection result information, so as to directly judge whether there is a multi-package situation based on the detection result information subsequently.

[0061] In an implementable manner, the detection terminal includes a first detection sensor and a second detection sensor vertically distributed from top to bottom, and the detection data includes first detection data collected by the first detection sensor and second detection data collected by the second detection sensor;

[0062] Parsing the detection data to obtain detection result information includes:

[0063] Determine the area interval corresponding to the first detection data detected continuously twice by the same first detection sensor as the detection area;

[0064] Count the detection quantity of the second detection data in each detection area, and generate detection result information based on the detection quantity.

[0065] The detection area in the embodiment of the present application can be understood as the cell area on the sorting line for placing the suspended package 4. To ensure that each suspended package 4 can be sorted to the correct shipping location finally, there should be at most one suspended package 4 in a detection area. The detection area is composed of two support columns 3 connected to the track, and the carrier corresponding to the suspended package 4 is placed on the load-bearing column between the two support columns of the detection area.

[0066] In the embodiment of the present application, as Figure 2 shown, multiple detection sensors 2 can be vertically arranged in the detection terminal 1, and the detection sensors 2 can be infrared sensors. Taking two detection sensors 2 as an example, the first detection sensor and the second detection sensor are respectively arranged from top to bottom in the detection terminal 1. The cloud server will first determine the detection area according to the first detection data detected by the first detection sensor. Specifically, when the support column 3 moves to the detection terminal 1, the infrared ray sent by the first detection sensor is blocked, and then the first detection data is generated. Therefore, the cloud server will determine the detection area according to the time interval of continuously detecting the first detection data. In addition, the second detection sensor can be used to detect the suspended package 4. When the suspended package 4 moves to the detection terminal 1, the infrared ray sent by the second detection sensor is blocked, and then the second detection data is generated. Therefore, the cloud server will count the number of the second detection data obtained within the detection area, that is, between two adjacent first detection data corresponding to the detection area, and use this as a basis to generate the detection result information.

[0067] In an implementable manner, determining the area interval corresponding to the first detection data continuously detected twice by the same first detection sensor as the detection area includes:

[0068] Determining the area interval corresponding to the first detection data continuously detected twice by the same first detection sensor as the detection area, and determining the time interval between the two detections of the first detection data;

[0069] Determining the detection area with the time interval greater than the preset time interval as the format chain area;

[0070] Determining the detection area with the time interval not greater than the preset time interval as the non-format chain area.

[0071] In the embodiment of the present application, as Figure 2As shown, the part of the screening line for conveying and hanging packages 4 is composed of connected format chains one by one. Due to objective reasons of the composition structure, there will also be a section that is not a format chain between two adjacent format chains. Although it is also possible to sort and identify the quantity of packages by hanging the packages 4 in the non-format chain area, under normal circumstances, it is generally desired that the hanging packages 4 are all hung in the format chain area, and there are no hanging packages 4 in the non-format chain area. Therefore, the cloud server will also determine whether the detected area determined at this time is a format chain area or a non-format chain area according to the time interval between the two first detection data corresponding to each detection area. Since the distance between the two pillars in the non-format chain area is small, a preset time interval will be set, and the detection area smaller than this preset time interval is the non-format chain area.

[0072] In an implementable manner, the detection terminal includes a second detection sensor, and the detection data includes the second detection data collected by the second detection sensor;

[0073] Parsing the detection data to obtain detection result information includes:

[0074] Obtain a preset statistical time period, the statistical time period includes a format chain time interval and a non-format chain time interval, the format chain time interval corresponds to the format chain area, and the non-format chain time interval corresponds to the non-format chain area;

[0075] Respectively count the detection quantities corresponding to the second detection data in the format chain area and the non-format chain area, and generate detection result information based on the detection quantities.

[0076] In the embodiments of the present application, as Figure 3 shown, only one second detection sensor for detecting the hanging package 4 can also be set in the detection terminal 1, and the second detection sensor can be an infrared sensor. Since the lengths of the format chain area and the non-format chain area are fixed and their distributions are regular, the statistical time period can be set in advance according to the initial state of the screening line, and the format chain time interval and the non-format chain time interval can be determined through the statistical time period. For example, the statistical time period is 0.7 s, where the first 0.2 s is the non-format chain time interval and the last 0.5 s is the format chain time interval. It can also be that the first 0.1 s and the last 0.1 s are the non-format chain time intervals, and the middle 0.5 s is the format chain time interval. After determining the statistical time period, it is possible to directly determine the current area category according to the running time of the screening line, and then generate detection result information in combination with the detection quantity of the second detection data during this time period.

[0077] In an implementable manner, the detection result information includes normal detection result information and abnormal detection result information;

[0078] Generating detection result information based on the detected quantity includes:

[0079] When the detected quantity is no more than one, generating normal detection result information;

[0080] When the detected quantity is no less than two, generating abnormal detection result information.

[0081] In the embodiment of the present application, the detection result information is divided into two types, one is normal detection result information and the other is abnormal detection result information. Since under normal circumstances, there should be at most one hanging package 4 in the format chain, the detection result information generated corresponding to the situation where the detected quantity is no more than one is used as the normal detection result information, and vice versa as the abnormal detection result information.

[0082] S102. When there is abnormal detection result information, determine the target detection terminal where the abnormal detection result information first appears, and divide the area from the previous detection terminal adjacent to the target detection terminal to the target detection terminal into the first abnormal area.

[0083] In the embodiment of the present application, if there is abnormal detection result information in the detection result information, it indicates that there is a situation where there are multiple packages in a single format chain on the screening line. At this time, the cloud server needs to determine the location where the multiple - package situation occurs, that is, the area where multiple packages first appear. For the target detection terminal where the abnormal detection result information first appears, its adjacent previous detection terminal did not detect an abnormality, so the multiple - package situation occurred when the hanging package 4 was conveyed between the two. Therefore, the cloud server will directly divide this area into the first abnormal area for the management personnel to accurately go to for investigation.

[0084] In an implementable manner, determining the first abnormal area corresponding to the target detection terminal includes:

[0085] When there is no previous detection terminal adjacent to the target detection terminal in the screening line, determine the position area of the target detection terminal as the first abnormal area;

[0086] When there is a previous detection terminal adjacent to the target detection terminal in the screening line, divide the area from the previous detection terminal adjacent to the target detection terminal to the target detection terminal into the first abnormal area.

[0087] In the embodiments of the present application, the determination of the first abnormal area is to help the staff quickly determine the location of the abnormal area when going for inspection, so as to help the staff troubleshoot faults. When determining the first abnormal area, it is first necessary to determine whether there is an adjacent previous detection terminal of the target detection terminal in the screening line. If not, it means that the target detection terminal is the first detection terminal on the screening line, and the area where multi-packet abnormality occurs is the position area corresponding to the target detection terminal. If there is, the position where multi-packet abnormality occurs may be any place between these two detection terminals, so the area between the two will be divided into the first abnormal area.

[0088] S103. Generate a first warning message based on the first abnormal area, and send the first warning message to a preset management terminal.

[0089] In the embodiments of the present application, the cloud server will generate a first warning message according to the first abnormal area. After the management personnel receive the first warning message through the preset management terminal, they can directly understand the location of the first abnormal area according to the first warning message, and then can directly go to the abnormal place for troubleshooting, improving the efficiency of the management personnel in handling abnormalities and reducing the number of multi-packet problems caused by abnormalities.

[0090] In an implementable manner, the method further includes:

[0091] Obtain the device distribution information in the first abnormal area, where the device distribution information includes device type information and device location information;

[0092] Determine the priority corresponding to each device type information based on a preset mapping relationship, and send the target device location information corresponding to the target device type information with the highest priority to the preset management terminal.

[0093] In the embodiment of the present application, after determining the first abnormal area, in order to further improve the troubleshooting efficiency of the management personnel, the cloud server will determine the priority troubleshooting positions in the first abnormal area. Exemplarily, a certain section of the area may consist of a section of conveying track plus a section of the hanging equipment area. Then, the probability of multi-packet situations occurring during the hanging of the hanging equipment area is higher, and the hanging equipment area should be preferentially troubleshot. Based on the above criteria, the cloud server will obtain the equipment distribution information within the first abnormal area to determine the types and positions of various equipment within the area. Then, through the pre-set mapping relationship, the priority of different equipment type information can be determined. The equipment with a higher priority is considered to be more likely to have multi-packet problems. Therefore, the target equipment position with the highest priority is sent to the preset management terminal to assist the management personnel in preferentially troubleshooting this position, improving the efficiency of abnormal troubleshooting, reducing the frequency of multi-packet abnormalities in the suspension chain system, and improving the efficiency of goods packing and warehousing.

[0094] In an implementable manner, the method further includes:

[0095] When the second detection data is detected in the non-format chain area, generate a second warning message and send the second warning message to the preset management terminal.

[0096] In the embodiment of the present application, it can be seen from the foregoing process that there will generally be no hanging packages 4 in the non-format chain area. Therefore, when the cloud server detects the second detection data in the non-format chain area, it is considered that an abnormality may have occurred at this time due to reasons such as manual hanging of packages by staff. The cloud server will generate a second warning message and send it to the preset management terminal of the management personnel to prompt them to go to check the situation in time and handle the abnormality.

[0097] In an implementable manner, the step of generating a second warning message when the second detection data is detected in the non-format chain area includes:

[0098] When the second detection data is detected in the non-format chain area, determine the target detection terminal that first detected the second detection data in the non-format chain area, and determine the second abnormal area corresponding to the target detection terminal;

[0099] Generate a second warning message based on the second abnormal area and send the second warning message to the preset management terminal.

[0100] In the embodiments of the present application, when there are multiple hanging packages 4 in a certain place in the format chain, the detection data of all subsequent detection terminals 1 will show abnormalities. In order to accurately determine the location where the abnormality occurs for the management personnel to conduct investigations, the cloud server will first determine the target detection terminal that first detects the abnormality, and thereby determine the corresponding second abnormal area. Among them, the determination process of the second abnormal area can be the same as the determination process of the first abnormal area, that is, first determine whether there are other adjacent detection terminals before the target detection terminal that first detects the abnormality. If not, directly determine the location area of the target detection terminal as the second abnormal area; if so, determine the area between the target detection terminal and its adjacent previous detection terminal as the second abnormal area. Through the division of the second abnormal area, it can be ensured that after receiving the second warning message, the management personnel can clearly understand the area where the abnormality occurs and then go to conduct investigations.
