Referring to fig. 1, fig. 1 is a schematic flowchart of a multi-target exception handling method based on a screening line according to an embodiment of the present application. In an embodiment of the present application, the method includes:

s101, continuously acquiring detection data uploaded by each detection terminal preset on a screening line, and analyzing the detection data to obtain detection result information.

The execution subject of the application can be a cloud server.

In this application embodiment, be used for carrying will be provided with a plurality of detection terminal in advance at the different positions of screening line on the screening line of the parcel of hanging of being about to shipment, the high in the clouds server will continuously acquire the testing data that each detection terminal uploaded to carry out the analysis to the testing data who acquires, generate testing result information, so that follow-up direct judgement whether there is many packages condition according to testing result information.

In an implementation manner, the detection terminal includes a first detection sensor and a second detection sensor which are vertically distributed from top to bottom, and the detection data includes first detection data acquired by the first detection sensor and second detection data acquired by the second detection sensor;

analyzing the detection data to obtain detection result information, including:

The detection area can be understood as a cell area on the screening line for placing the hanging parcel 4 in the embodiment of the present application. To ensure that each hanging package 4 can be sorted to the correct delivery location, there should be at most one hanging package 4 in one detection area. The detection area is formed by connecting two support columns 3 with the track, and the carrier corresponding to the hanging package 4 is placed on the bearing column between the two support columns of the detection area.

In the embodiment of the present application, as shown in fig. 2, a plurality of detection sensors 2 may be vertically distributed in the detection terminal 1, and the detection sensors 2 may be infrared sensors. Taking two detection sensors 2 as an example, the detection terminal 1 is respectively provided with a first detection sensor and a second detection sensor from top to bottom. The cloud server first determines the detection area according to the first detection data detected by the first detection sensor, specifically, when the pillar 3 moves to the detection terminal 1, the infrared ray sent by the first detection sensor is stopped, and then the first detection data is generated, so the cloud server determines the detection area through the time interval of continuously detecting the first detection data. In addition, the second detection sensor can be used for detecting the hanging parcel 4, and when the hanging parcel 4 moves to the detection terminal 1, the infrared ray sent by the second detection sensor is stopped, and then the second detection data is generated. Therefore, the cloud server counts the number of second detection data acquired between two adjacent first detection data corresponding to the detection area in the detection area, and generates detection result information based on the number of second detection data acquired between two adjacent first detection data corresponding to the detection area.

In one possible implementation manner, the detection terminal includes a second detection sensor, and the detection data includes second detection data collected by the second detection sensor;

analyzing the detection data to obtain detection result information, including:

In the embodiment of the present application, as shown in fig. 3, only one second detection sensor for detecting the hanging package 4 may be disposed in the detection terminal 1, and the second detection sensor may be an infrared sensor. Because the lengths of the format chain region and the non-format chain region are fixed and the distribution of the format chain region and the non-format chain region is 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 0.7s, where the first 0.2s is the non-trellis chain time interval and the last 0.5s is the trellis chain time interval. Alternatively, the first 0.1s and the last 0.1s may be the non-trellis time interval, and the middle 0.5s may be the trellis time interval. After the statistical time period is determined, the current region type can be determined directly according to the running time of the screening line, and then the detection result information is generated by combining the detection number of the second detection data in the time period.

In one implementation, the detection result information includes normal detection result information and the abnormal detection result information;

the generating of the detection result information based on the detection number comprises:

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. Under normal conditions, at most only one hanging parcel 4 should exist in the format chain, so that the detection result information generated correspondingly under the condition that the detection quantity is not more than one is taken as normal detection result information, and otherwise, the detection result information is taken as abnormal detection result information.

S102, when the abnormal detection result information exists, determining and marking the target cell corresponding to the abnormal detection result information.

The anomaly detection result information can be understood as detection result information representing anomaly in result in the embodiment of the application.

In the embodiment of the present application, if there is abnormal detection result information in the detection result information obtained in the foregoing process, it indicates that a multi-packet abnormal condition occurs. In order to automatically handle multiple packets of anomalies, the cloud server needs to confirm and mark the target cells in which the anomaly detection result information appears. The target cell may be a trellis chain region or a non-trellis chain region.

In one possible implementation, step S102 includes:

The abnormal detection data can be understood as detection data corresponding to abnormal detection result information in the embodiment of the application.

In the embodiment of the application, since the detection result information is obtained according to the detection data, the transportation speed of the screening line is also fixed and determined. Therefore, according to the running speed of the screening line and the data detection time of the collected abnormal detection data, the unit cell of a plurality of abnormal problems can be determined and marked so as to continuously track the position of the abnormal problem.

S103, all the target carriers of the target cells are input into a buffer temporary storage area closest to the target cells, and the target carriers in the buffer temporary storage area are output to the idle cells of the screening line one by one.

In the embodiment of the application, the sorting line is connected with a plurality of buffer temporary storage areas besides the corresponding sorting and packing channel tracks. The hanging parcel is hung on the hanging carrier, and the buffer temporary storage area can be a section of semicircular track and is used for conveying the hanging carrier with a plurality of abnormal parcels back to the screening line after being buffered by the buffer temporary storage area. Specifically, the buffer storage area closest to the target cell is determined, and when the target cell moves to the buffer storage area, the cloud server tracks the hanging carrier in the control target cell into the buffer storage area. Then, the cloud server determines that no idle cell on the screening line is hung with a hanging carrier, so that the target carriers in the buffer temporary storage area are output to different idle cells one by one, separation of multiple carriers in the same cell is realized, multiple packages of abnormal conditions can be processed independently when multiple packages of abnormal conditions occur, and the cells finally output to a sorting position are guaranteed to be normal.

In one embodiment, the outputting each target vehicle in the buffer to a free cell of the screening line one by one includes:

determining free cells without hanging carriers based on the detection data;

In the embodiment of the present application, as can be seen from the foregoing process, each cell passes through, the multiple abnormal packets are determined according to the detection data, and this process can also be used to determine whether there is a hanging carrier in the cell, so as to determine an idle cell. When the free cell passes through the buffer area, the cloud server controls a target carrier in the buffer area to be output to the free cell. By repeating the process, the target carriers can be respectively output to different idle cells so as to realize the processing of the multi-packet exception.
