Alarm method, system, equipment and medium based on sorting error in logistics sorting

Abstract

The present invention proposes an alarm method, system equipment and medium based on sorting errors in logistics sorting. The method includes recording the unloading time T1 and unloading slot A1 of each package through a sorting module, and compiling multiple data into an information list P, and recording the unloading time T2 and unloading slot A2 of multiple packages through a monitoring module, setting a time threshold H, and intercepting the sub-segment P1 of the information list P in the time interval [T2-H, T2], comparing the information recorded by the sorting module with the information recorded by the monitoring module, and judging whether there is unloading information. If not, it means that at time T2, there is a parcel sorting error at the A2 slot, and an alarm is issued; if a parcel is always detected in a certain sorting slot, it means that the slot is blocked, and at this time, the slot is automatically locked, the unloading is stopped, and an alarm is issued. The present invention can prevent the problems of parcel sorting errors and slot blocking during the sorting process, and greatly reduce the economic losses caused by sorting errors.

Description

Technical Field

[0001] The present invention relates to the technical field of logistics sorting, and in particular to an alarm method, system, equipment and medium based on sorting errors in logistics sorting. Background Art

[0002] With the rapid development of the express delivery industry, the application of automated logistics sorting equipment is becoming more and more widespread. Automated logistics sorting equipment can be divided into linear cross-belt sorting machines and circular cross-belt sorting machines. The parcel is scanned by the parcel supply table to obtain parcel information, and then put on the trolley through the conveyor belt. When the trolley reaches the corresponding destination grid, it can carry out the unloading action to complete the sorting task. The whole process is highly automated and intelligent.

[0003] However, although the current automated logistics sorting equipment can achieve a high level of sorting accuracy, there are still cases where express delivery is missorted. This will not only lead to the need for re-sorting at a later stage, reducing sorting efficiency, but will also cause significant manpower and economic losses to express delivery companies. In order to alleviate the misclassification situation, the following methods are usually used in express sorting. First, query the misclassified items through the traceability system to understand the reasons for the misclassification and make targeted adjustments. Specifically, the traceability system needs to install multiple monitors around the sorting site line. These monitors will save video clips of the trolley unloading and record the trolley unloading situation. According to the trolley unloading situation, the cause of the misclassification can be known; second, the number of misclassified items is reduced through the correction system. However, due to the irregular operation of the sorting staff, the location of the package is not in the central area when it is loaded, which can easily lead to misclassification. The correction system detects the position of the package on the trolley and adjusts the unloading time to avoid misclassification; third, the grid is automatically locked when the package is full and the unloading is stopped. When the cumulative weight of the package exceeds the set threshold, the grid is locked. When the parcel storage bag is full, if the staff fails to replace the new empty package in time, it may cause grid blockage, which leads to misclassification.

[0004] The above methods can reduce the number of missorting to a certain extent, but there are still problems such as delayed response and limited effect, and it is impossible to alarm the wrong sorting in time. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes an alarm method, system equipment and medium based on sorting errors in logistics sorting, which can promptly alarm incorrectly sorted packages and effectively reduce the situation of incorrect sorting of logistics packages.

[0010] S4: Set a time threshold H, based on T2 recorded in S3 and the corresponding A2, and A1 recorded in the information list P in S2, within the time interval [T2-H, T2], intercept the information list P1 when T1 is within the time interval [T2-H, T2], and compare and determine whether A2 coincides with the A1 data in P1. If so, there is information about the next item, and the parcels in the sorting grid are sorted correctly; if not, there is no information about the next item, and the parcels in the sorting grid are sorted incorrectly, and an alarm is issued;

[0011] S5: In S3, when the monitoring module detects that there is always a package on the sorting grid, it means that the sorting grid is blocked; the monitoring module transmits a grid blocking signal to the main control module, and the sorting grid is automatically locked by the locking component, the unloading of the package is stopped, and an alarm is issued.

[0012] In an optional embodiment, the issuing of an alarm includes:

[0013] The corresponding sorting grid issues an alarm through an alarm module;

[0014] Or, the sorting grid is automatically locked by a locking component to stop unloading;

[0015] Alternatively, the corresponding sorting grid sends out an alarm through an alarm module, and at the same time, the sorting grid is automatically locked through a locking component to stop unloading.

[0016] The second aspect of the present invention discloses an alarm system based on sorting errors in logistics sorting, the system comprising:

[0017] The sorting module includes a sorting grid, a locking grid component arranged on the sorting grid, and an alarm module. The sorting module is used to obtain package information and sort packages, and transmit the packages to the corresponding sorting grid; the alarm module is arranged on one side of the sorting grid, and is used to alarm the abnormal situation of the package in the sorting grid;

[0018] A plurality of monitoring modules are arranged above the sorting grid, and are used to monitor the images of the parcels being dropped in the sorting grid, and record the grid number and the time when the parcels are finally dropped;

[0019] The master control module is in communication with the monitoring module and the sorting module, and is used to summarize information and issue corresponding control executions.

[0020] In an optional embodiment, the sorting module further includes a locking grid component, the locking grid component includes a locking grid warning device, and the locking grid warning device is electrically connected to the sorting module.

[0021] In an optional embodiment, the alarm device is a sound effect alarm or a light effect alarm.

[0022] In an optional embodiment, the lock warning device is a sound effect alarm or a light effect alarm.

[0023] In an optional embodiment, the general control module, the monitoring module and the sorting module communicate with each other through the TCP protocol to exchange information.

[0024] In an optional embodiment, the monitoring module is a monitoring camera.

[0025] The third aspect of the present invention discloses an alarm device based on sorting errors in logistics sorting, comprising:

[0026] at least one processor, and

[0027] a memory communicatively connected to the at least one processor; wherein,

[0028] The memory stores instructions executable by the at least one processor, and the instructions are executed by the at least one processor so that the at least one processor can execute the alarm method based on sorting errors in logistics sorting as described in any one of the items disclosed in the first aspect of the present invention.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] In the present invention, the sorting module records the unloading time T1 and unloading grid A1 of each parcel, and collects a large amount of parcel data into an information list P, and the monitoring module records the unloading time T2 and unloading grid A2 of multiple parcels, sets the time threshold H, and intercepts the sub-segment P1 of the information list P in the time interval [T2-H, T2], compares the information recorded by the sorting module with the information recorded by the monitoring module, and determines whether there is unloading information. If there is unloading information, the parcels in the sorting grid are sorted correctly; if there is no unloading information, the parcels in the sorting grid are sorted incorrectly, that is, it means that at time T2, the A2 grid has a parcel sorting error, and an alarm is issued in time. In addition, by real-time monitoring whether there are parcels in the sorting grid, if a parcel is always detected in a certain sorting grid, it means that the grid is blocked; the monitoring module transmits the blocking signal to the master control module, and the sorting grid is automatically locked through the locking component, stops unloading, and issues an alarm. In this way, an alarm is issued for the obstruction of the sorting grid during the logistics sorting process, so that the staff can deal with the situation in time, prevent the problem of continuous blocking of the sorting grid by packages, and thus improve the logistics sorting efficiency. Therefore, the alarm method based on sorting errors in logistics sorting provided by the present invention can greatly reduce the situation of sorting errors under the cooperation of the sorting module and the monitoring module, and through the adjustment activities of the general control module, so that when a fault occurs during the sorting process, an alarm can be issued in time and quickly, ensuring that the staff can arrive as soon as possible to deal with the fault problem, prevent the problem of continuous missing, wrong or blocked packages, and greatly reduce the economic losses caused by sorting errors.

[0041] Example 1

[0042] See also Figure 1 The embodiment of the present invention discloses an alarm method based on sorting errors in logistics sorting, comprising:

[0043] S1: Obtain the parcel information through the sorting module, transfer the parcel to the corresponding sorting slot according to the parcel information, and record the parcel unloading time as T1 and the corresponding unloading slot as A1, wherein T1 and the corresponding A1 are both recorded in the master control module;

[0044] S2: When sorting a large number of parcels, an information list P is set in the master control module, and the information list P records the unloading time T1 of each parcel and the corresponding unloading slot A1; the information list P in this step can also be understood as a data set collected by the unloading time T1 of multiple parcels and the corresponding unloading slot A1 recorded by the sorting module, which records the T1 and A1 of each parcel, so that the corresponding data can be quickly found when searching for matching data later;

[0045] S3: The monitoring module is arranged above the sorting module, and is used to monitor the image and position change of the package in real time, and record the time when the package is placed in the sorting slot as T2, and the corresponding slot for placing the package as A2;

[0046] S4: Set a time threshold H, according to T2 recorded in S3 and the corresponding A2, and A1 recorded in the information list P in S2, within the time interval [T2-H, T2], intercept the information list P1 when T1 is within the time interval [T2-H, T2], and compare and determine whether A2 coincides with the A1 data in P1. If so, there is information about the next piece, and the parcels in the sorting grid are sorted correctly; if not, there is no information about the next piece, and the parcels in the sorting grid are sorted incorrectly, and an alarm is issued.

[0047] Specifically, in S3, the method of recording the package image and position change by shooting a video by the monitoring module can facilitate the staff to quickly find the corresponding wrongly sorted package and its corresponding sorting grid position by reviewing the video when an error sorting occurs later.

[0048] Specifically, in S4, it can be understood that a time threshold H is set, and T2 and A2 recorded by the monitoring module in S3 are compared with the data recorded in the information list P in S2, and the information list P1 when T1 is within the time interval [T2-H, T2] is intercepted in the information list P as a sub-segment for data comparison, narrowing the comparison range, and judging whether the A2 grid overlaps with the A1 data in P1. If so, there is the next piece information, and the parcels in the sorting grid are sorted correctly; if not, that is, no matching next piece information is found, it means that at time T2, a wrong piece has been sorted at the A2 grid.

[0049] In the present invention, the sorting module records the unloading time T1 and unloading slot A1 of each parcel, and collects a large amount of parcel data into an information list P, and the monitoring module records the unloading time T2 and unloading slot A2 of multiple parcels. By setting a time threshold H and intercepting the sub-segment P1 of the information list P within the time interval [T2-H, T2], the information recorded by the sorting module is compared with the information recorded by the monitoring module to determine whether there is unloading information. If there is unloading information, the parcels in the sorting slot are sorted correctly; if there is no unloading information, the parcels in the sorting slot are sorted incorrectly, that is, at time T2, a parcel sorting error occurred at slot A2, and an alarm can be issued in time. Therefore, the alarm method based on sorting errors in logistics sorting provided by the present invention can greatly reduce the situation of sorting errors under the cooperation of the sorting module and the monitoring module, as well as through the adjustment activities of the general control module, so that when a fault occurs during the sorting process, an alarm can be given in time and quickly, ensuring that the staff can arrive to deal with the fault problem as soon as possible, preventing the problem of continuous missing, wrong or blocked packages, and greatly reducing the economic losses caused by sorting errors.

[0050] Example 2

[0051] This embodiment provides a sorting error alarm method, which is mainly caused by a parcel blocking a sorting grid, specifically:

[0052] SA. Obtain the parcel information through the sorting module, transfer the parcel to the corresponding sorting slot according to the parcel information, and record the parcel unloading time as T1 and the corresponding unloading slot as A1, wherein T1 and the corresponding A1 are both recorded in the master control module;

[0053] SB. The monitoring module is used to monitor in real time whether there are packages in the sorting grid. If a package is always detected in a sorting grid, it means that the grid is blocked;

[0054] SC. The monitoring module transmits the blocking signal to the main control module, and the sorting grid is automatically locked through the locking component, stopping the unloading of items and sounding an alarm.

[0055] In this way, an alarm is issued for obstruction of the sorting grid during the logistics sorting process, so that the staff can respond to the situation in time to prevent the problem of continuous obstruction of the sorting grid by packages, thereby improving the logistics sorting efficiency.

[0056] In an optional embodiment, the issuing of an alarm includes:

[0057] The corresponding sorting grid issues an alarm through the alarm module; this alarm mode is applicable to the case where a parcel is sorted incorrectly within the time interval [T2-H, T2] as in S4 of Example 1;

[0058] Or, the sorting grid opening is automatically locked by a locking component to stop unloading; this situation is applicable to the situation where a package blocks the sorting grid opening in the SB of Example 2;

[0059] Or, the corresponding sorting grid sends out an alarm through the alarm module, and at the same time, the sorting grid is automatically locked by the locking component to stop unloading; this situation is suitable for alarming the sorting error situations in Example 1 and Example 2.

[0060] like Figure 2 As shown, the second aspect of the present invention discloses an alarm system based on sorting errors in logistics sorting, the system comprising:

[0061] The sorting module includes a plurality of sorting slots, a locking slot assembly provided on the sorting slots, and an alarm module. The sorting module is used to obtain package information and sort packages, and transmit the packages to the corresponding sorting slots. The alarm module is provided on one side of the sorting slots, and is used to alarm the abnormality of the packages in the sorting slots.

[0062] A plurality of monitoring modules are arranged above the sorting modules, and are used to monitor the images of the parcels being dropped in the sorting grids, and record the grid number and the time when the parcels are finally dropped;

[0063] The master control module is connected to the plurality of monitoring modules and the sorting modules for collecting information and issuing corresponding control executions.

[0064] When the alarm system executes the alarm method in Example 1, the sorting module records the unloading time T1 and unloading slot A1 of each parcel, and collects a large amount of parcel data into an information list P, and the monitoring module records the unloading time T2 and unloading slot A2 of multiple parcels under the corresponding sorting slot. By setting the time threshold H, in the same unloading slot, that is, when A1=A2, in the time interval [T2-H, T2], the information recorded by the sorting module is compared with the information recorded by the monitoring module to determine whether there is unloading information. If there is unloading information, the parcels in the sorting slot are sorted correctly; if there is no unloading information, the parcels in the sorting slot are sorted incorrectly, that is, at time T2, the parcel sorting error occurs in the A1 (i.e. A2) slot, and then, the alarm module sends an alarm to promptly remind the staff of the information that there is a sorting error in the sorting slot. By troubleshooting the sorting error in this way, the problem caused by the error can be solved in time.

[0065] When the alarm system executes the alarm method in Example 2, specifically, when a package is always detected in a certain sorting grid, it means that the grid is blocked. At this time, the sorting grid is locked by the locking component in time, which can prevent the package from being continuously transferred to the sorting grid, thereby avoiding causing greater sorting errors.

[0066] In an optional embodiment, the sorting module further includes a grid lock component, and the grid lock component further includes a grid lock warning device, and the grid lock warning device is electrically connected to the sorting module. When a parcel blocks a grid opening during the sorting process, the grid lock component promptly controls the sorting grid opening to prevent the sorting module from continuously delivering parcels to the grid opening. At the same time, the grid lock warning device sounds an alarm to remind the staff that a sorting error has occurred here, so that the situation can be solved in time.

[0067] In an optional embodiment, the alarm device is a sound effect alarm or a light effect alarm. When the alarm device is a sound effect alarm, the alarm signal it sends is an abnormal sound alarm, such as a long beep or a pre-recorded alarm sound effect; when the alarm device is a light effect alarm, the alarm signal it sends is an abnormal light effect alarm, such as a red or yellow warning light.

[0068] In an optional embodiment, the lock warning device is a sound effect alarm or a light effect alarm. When the lock warning device is a sound effect alarm, the alarm signal it sends is an abnormal sound alarm, such as a long beep or a pre-recorded alarm sound effect; when the lock warning device is a light effect alarm, the alarm signal it sends is an abnormal light effect alarm, such as a red or yellow warning light.

[0069] In an optional embodiment, the master control module, the monitoring module and the sorting module communicate with each other through the TCP protocol to exchange information. Specifically, the TCP protocol communication mode has the characteristics of reliable information transmission and congestion control, which can greatly reduce the communication sluggishness caused by network jams and improve the efficiency and accuracy of information exchange.

[0070] In an optional embodiment, the monitoring module is a monitoring camera. The monitoring camera is used to capture images of package delivery, so that the images of package delivery and unloading can be saved for a long time or for a certain period of time, thereby extending the flexibility of the system.
