[0070] The technical solutions in the embodiments of the present application will be described clearly and completely below with the help of the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without any creative effort belong to the scope of protection of the present application.

[0071] Referring to Figure 1 The embodiment of the present application discloses an airport luggage automatic sorting system luggage tracking analysis alarm system, which comprises: a control and information subsystem, a preprocessing subsystem, a luggage tracking analysis alarm subsystem and an alarm server; wherein:

[0072] A control and information subsystem is configured to control the baggage conveying according to a preset baggage path and obtain system configuration information according to the preset baggage path;

[0073] The system configuration information includes a flight time period, a flight time length, a baggage source information detection time length, a baggage circulation detection time length threshold, a baggage circulation detection position, a baggage circulation number threshold, a flight baggage analysis start time, a flight baggage analysis end time, a baggage analysis end state, a baggage analysis start position, a baggage analysis end position, an analysis exception position list, a sorting exception category, a sorting exception alarm threshold, a baggage sorting node position list, a node position timeout threshold, and an early-arriving baggage storage timeout time length.

[0074] A preprocessing subsystem is configured to screen the baggage to be analyzed based on the system configuration information and obtain screened baggage to be analyzed.

[0075] A baggage tracking analysis alarm subsystem is configured to perform baggage tracking analysis on the screened baggage to be analyzed based on the system configuration information and alarm an abnormal analysis result.

[0076] An alarm server is configured to process alarm information.

[0077] The flight time period and the flight time length are derived from flight information and flight resource allocation information provided by baggage processing information (BPM), including a flight number, a flight date, a destination airport, a flight state, a planned departure time, an expected departure time, a flight resource number, an opening time, and a closing time.

[0078] The preprocessing subsystem includes a first non-entry sorting judgment module, a second non-entry sorting judgment module, a first sorting normal judgment module, a processing information abnormal judgment module, and a second sorting normal judgment module.

[0079] The first non-entry sorting judgment module is configured to judge whether the flight is between the flight baggage analysis start time and the flight baggage analysis end time. If not, the corresponding baggage to be analyzed is excluded. If yes, it is judged whether the current state of the baggage is in the baggage analysis end state. If yes, the corresponding baggage to be analyzed is excluded, and the remaining first baggage to be analyzed is obtained. By defining the flight baggage analysis start and end time and the baggage analysis end state, the baggage of the end flight and the normally sorted baggage can be excluded, and the number of baggage analysis is significantly reduced.

[0080] The second "Not Entering Sorting" judgment module is used to obtain the current location of the first baggage to be analyzed and determine whether the current location of the first baggage to be analyzed is in the analysis exception location list. If it is, the corresponding first baggage to be analyzed is excluded. If not, it then determines whether the current location of the first baggage to be analyzed is in the baggage sorting node location list. If not, the corresponding first baggage to be analyzed is excluded, leaving the second baggage to be analyzed. For example, VIP, CIP, oversized baggage (OOG), or transit baggage that will not enter the baggage sorting system do not need to be sorted, tracked, or analyzed. By defining the analysis exception location list and the baggage sorting node location list, baggage that has not entered the automatic sorting system can be effectively excluded, reducing the number of baggage analyzed and the false alarm rate.

[0081] The first sorting normal judgment module is used to determine whether the time it takes for the second baggage to be analyzed to leave the current location is greater than the node location timeout threshold; if not, the corresponding baggage to be analyzed is excluded, leaving the third baggage to be analyzed; by defining the node location timeout threshold, baggage that is sorted normally can be effectively excluded, further reducing the number of baggage to be analyzed;

[0082] The information anomaly judgment module is used to determine whether the third baggage to be analyzed has ever been in the baggage processing history information as baggage unloading status and baggage sorting completion status; if so, the corresponding baggage to be analyzed is excluded, leaving the fourth baggage to be analyzed.

[0083] The second sorting normal judgment module is used to obtain the location information of the remaining fourth baggage to be analyzed from the baggage processing history information. If the location information contains the baggage analysis end position, the baggage sorting is considered normal, the corresponding baggage to be analyzed is excluded, and the remaining baggage to be analyzed is used as the filtered baggage to be analyzed. Through this second sorting normal judgment module, the baggage history of baggage that has timed out of the baggage departure node is analyzed, and baggage that has reached the sorting end position is excluded, so as to exclude false alarms of normal sorting but abnormal baggage processing information.

[0084] See Figure 2 As shown, the aforementioned baggage tracking and analysis alarm subsystem includes: a baggage source information detection module, a baggage sorting process analysis module, a baggage loop detection module, and a baggage delay detection module; wherein:

[0085] The baggage origin information detection module is used to detect whether baggage origin information has been obtained within the baggage origin information detection period during the flight time. If it is not obtained, it indicates that there is an abnormality in baggage origin information for the corresponding flight, and an alarm for not receiving baggage origin information is issued. Among them, baggage origin information (BSM) comes from baggage handling information (BPM) and includes baggage barcode number, flight number, flight date, destination airport, event time, check-in counter number and other information.

[0086] The luggage sorting process analysis module is configured to compare the time difference between the luggage analysis start position and the luggage analysis end position of the post-screening luggage to be analyzed with a luggage circulation detection duration threshold value; if the time difference is greater than the luggage circulation detection duration threshold value, it is determined that the detection is overdue; wherein the luggage analysis start position and the luggage analysis end position are key nodes of the luggage tracking analysis alarm system for multiple tracked luggage, and luggage information including luggage position, luggage barcode, time, etc. can be obtained at these two positions by using RFID technology or related identification technology;

[0087] The luggage circulation detection module is configured to obtain detection information of the post-screening luggage to be analyzed passing through the luggage circulation detection position and record the number of passes in the case of detection overdue; compare the number of passes with a luggage circulation number threshold value; if the number of passes is greater than the luggage circulation number threshold value, an circulation overdue alarm is issued; through the luggage circulation detection module, the number of times (greater than or equal to 2 times) that the luggage passes through the same position of the sorting line in the luggage tracking analysis alarm system can be detected;

[0088] The luggage retention detection module is configured to compare the current position of the post-screening luggage to be analyzed with the early-arriving luggage position list; if the current position is in the early-arriving luggage position list, compare the time difference between the scheduled departure time of the flight and the current time to determine whether it is less than the early-arriving luggage storage (EBS) overdue duration; if so, a luggage retention alarm is issued.

[0089] The luggage tracking analysis alarm subsystem described above further includes a luggage sorting anomaly judgment module configured to obtain the last time of appearance of the post-screening luggage to be analyzed, compare it with the current time, and form a luggage sorting anomaly list based on the time comparison difference according to the sorting anomaly categories; specifically:

[0090] If the time comparison difference exceeds a first threshold value, it is determined that the post-screening luggage to be analyzed does not arrive at the relevant tracking position in the luggage sorting node position list within the specified time, at which time a first-level anomaly list is formed; this type of abnormal situation can be indicated by a blue display light, which represents that the abnormal situation is not serious compared to other situations, so this type of abnormal situation generally does not need to be handled;

[0091] If the time comparison difference exceeds a second threshold value, it is determined that the post-screening luggage to be analyzed does not arrive at the luggage analysis end position within the specified time, at which time a second-level anomaly list is formed; this type of abnormal situation can be indicated by a yellow display light, which represents that the abnormal situation is relatively serious compared to other situations, at which time the sorting situation of the luggage needs to be continuously monitored by the operator;

[0092] If the time contrast difference exceeds the third threshold value, it is determined that the luggage to be analyzed after screening has abnormal situations of luggage loss, luggage falling, cycle timeout and luggage retention in the sorting process, and a third abnormality list is formed. When such abnormal situations occur, a red display lamp can be used to indicate that the abnormal situation is very serious.

[0093] The luggage sorting abnormality judgment module further includes a luggage loss analysis module for performing secondary analysis on the luggage with abnormal situations of luggage loss in the third abnormality list as target luggage. Specifically, it includes judging whether the target luggage is tracking failure luggage or unread barcode luggage in the corresponding period at the next sorting node position.

[0094] If not, it is determined that the target luggage has sorting abnormality, and the sorting abnormality alarm threshold is triggered to perform sorting abnormality alarm to remind the operator to immediately handle the sorting abnormality to ensure that the luggage will not be late;

[0095] If yes, the previous piece of luggage and the next piece of luggage of the target luggage at the current position are obtained, and it is detected whether the target luggage is still between the previous piece of luggage and the next piece of luggage at the next sorting node position. If not, it is determined that the target luggage has stuck or fallen, and the sorting abnormality alarm threshold is triggered to perform sorting abnormality alarm to remind the operator to immediately handle the sorting abnormality to ensure that the luggage will not be late;

[0096] Based on the luggage loss analysis module, false alarms caused by unread and loss of luggage can be effectively excluded.

[0097] In another embodiment, the control and information subsystem stores system configuration information.

[0098] In another embodiment, the control and information subsystem is respectively connected with the luggage tracking analysis alarm subsystem and the alarm server control.

[0129] (2) Determine the flight details that need to be analyzed according to the flight baggage analysis period;

[0130] (3) Compare the current state information of the flight baggage with the baggage state information after sorting is completed; if the baggage is already in the analysis end state, no analysis is needed, otherwise the analysis is performed to determine the baggage details that need to be tracked and analyzed; by defining the baggage analysis end state information, the baggage list that needs to enter the next step of analysis is determined, and the number of baggage analysis is reduced;

[0131] (4) Compare the current position of the baggage with the analysis exception position list and the baggage sorting node position list of the automatic sorting system; if the current position of the baggage does not belong to the analysis exception position list and belongs to the sorting node list, the baggage tracking is analyzed, otherwise it is not analyzed, so as to exclude the baggage that is not in the automatic sorting system such as large baggage, VIP baggage, etc.

[0132] (5) Analyze whether the time for the baggage to leave the current position is greater than the node position timeout threshold; if yes, enter the next step of analysis, otherwise do not analyze;

[0133] (6) Analyzing whether the luggage unloading state (receiving the BSM report of the departure system luggage deletion, the passenger canceling the luggage consignment) or the luggage analysis end state (after the luggage sorting is completed, the control and information system receives the luggage processing information of the third party system, and the current state of the luggage is not the luggage analysis end state) appears in the luggage processing history information. If it appears, it is not analyzed. If not, it enters the next step of analysis.

[0134] (7) Analyzing the position information of the luggage processing history information and the sorting end position list. If the position information belongs to the sorting end position list, it is considered that the luggage sorting is normal and does not need to be analyzed (for example, the luggage arrives at the manual coding station and is forcibly specified for sorting by the operator). Otherwise, it enters the next step of analysis.

[0135] (8) Comparing the current position of the luggage with the early luggage position list. If it is, it is compared whether the flight expected takeoff time minus the current time is less than the early luggage storage timeout duration. If it is, the luggage sorting abnormal level is set to red, and the luggage sorting abnormal list is formed. The early luggage retention alarm is sent to the alarm server. Otherwise, it is judged to be normal sorting.

[0136] (9) Judging whether the time when the luggage leaves the current position is greater than the first level threshold value (blue level threshold value). If it is, the luggage sorting abnormal level is set to blue, and the luggage first level sorting abnormal list is formed.

[0137] (10) Judging whether the time when the luggage leaves the current position is greater than the second level threshold value (yellow level threshold value). If it is, the luggage sorting abnormal level is set to yellow, and the luggage second level sorting abnormal list is formed.

[0138] (11) Judging whether the time when the luggage leaves the current position is greater than the third level threshold value (red level threshold value). If it is, the luggage sorting abnormal level is set to red, and the luggage third level sorting abnormal list is formed.

[0139] (12) When the current position of the luggage is not in the early luggage position and the luggage sorting abnormal level is red, the luggage tracking failure or unread barcode analysis is performed. Whether there is a tracking failure or an unread barcode luggage in the next node position that the luggage should pass through. The previous luggage and the next luggage of the current position of the luggage also pass through the same next node position. Their front and rear positions in the same next node position are the same. If there is no such luggage, the luggage lost alarm is sent to the alarm server.
