Description

Technical Field

[0001] The present invention relates to the technical field of automatic luggage sorting, and more particularly to a luggage tracking, analyzing and alarming system and method for an automatic luggage sorting system at an airport. Background Art

[0002] With the rapid development of my country's civil aviation industry, more and more passengers choose to travel by plane, and more passengers' luggage needs to be checked in. Due to the complexity of baggage and baggage sorting and processing systems, various sorting anomalies will inevitably occur during the automatic sorting process, and the large amount of baggage makes it difficult for operators to find baggage sorting anomalies.

[0003] At present, in the relevant technology, the number of luggage is checked only after the luggage is sorted or loaded, and the problem of missing luggage is discovered at this time; however, in large-scale sorting systems with very long sorting lines, the luggage may get lost, fall, or circulate during the sorting process, resulting in late delivery of luggage and affecting the normal travel of passengers.

[0004] Therefore, how to detect baggage sorting anomalies as timely as possible and effectively handle the anomalies is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] In view of the above problems, the present invention provides a baggage tracking, analysis and alarm system and method for an automatic baggage sorting system at an airport, so as to at least solve some of the technical problems mentioned in the above background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] On the one hand, the present invention provides a baggage tracking analysis alarm system for an airport baggage automatic sorting system, comprising: a control and information subsystem, a pre-processing subsystem, a baggage tracking analysis alarm subsystem and an alarm server;

[0008] The control and information subsystem is used to control the baggage conveyance according to the preset baggage path, and to configure the system according to the preset baggage path to obtain system configuration information;

[0009] System configuration information includes: flight time, flight duration, baggage source information detection duration, baggage cycle detection duration threshold, baggage cycle detection position, baggage cycle number threshold, flight baggage analysis start time, flight baggage analysis end time, baggage analysis end status, baggage analysis start position, baggage analysis end position, analysis exception position list, sorting exception category, sorting exception alarm threshold, baggage sorting node position list, node position timeout threshold, early baggage storage timeout duration;

[0010] The pre-processing subsystem is used to screen the baggage to be analyzed based on the system configuration information to obtain the screened baggage to be analyzed;

[0011] The baggage tracking analysis alarm subsystem performs baggage tracking analysis on the baggage to be analyzed after screening based on the system configuration information, and issues an alarm for abnormal analysis results;

[0012] The alarm server is used to process the alarm information.

[0013] Further, the pre-processing 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 abnormality judgment module and a second sorting normal judgment module;

[0014] The first non-entering sorting judgment module judges 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 so, it is judged whether the current state of the baggage is in the baggage analysis end state; if so, the corresponding baggage to be analyzed is excluded, and the first baggage to be analyzed remains;

[0015] The second non-entering sorting judgment module is used to obtain the current position of the first baggage to be analyzed, and judge whether the current position of the first baggage to be analyzed is in the analysis exception position list; if so, the corresponding first baggage to be analyzed is excluded; if not, it is judged whether the current position of the first baggage to be analyzed is in the baggage sorting node position list; if not, the corresponding first baggage to be analyzed is excluded, and the second baggage to be analyzed remains;

[0016] The first sorting normal judgment module is used to judge whether the time when the second baggage to be analyzed leaves the current position is greater than the node position timeout threshold; if not, the corresponding baggage to be analyzed is excluded, and the third baggage to be analyzed remains;

[0017] The processing information abnormality judgment module is used to judge whether the third baggage to be analyzed has appeared in the baggage unloading state and the baggage sorting completion state in the baggage processing history information; if so, the corresponding baggage to be analyzed is excluded, and the fourth baggage to be analyzed remains;

[0018] The second normal sorting judgment module is used to obtain the position information of the fourth baggage to be analyzed from the baggage processing history information. If the position information contains the baggage analysis end position, it is considered that the baggage sorting is normal, the corresponding baggage to be analyzed is excluded, and the remaining baggage to be analyzed is used as the post-screening baggage to be analyzed.

[0019] Furthermore, the baggage tracking analysis and alarm subsystem includes: a baggage source information detection module, a baggage sorting process analysis module, a baggage circulation detection module and a baggage detention detection module;

[0020] The baggage source information detection module is used to detect whether the baggage source information is obtained within the baggage source information detection time within the flight period; if not, an alarm of not receiving the baggage source information is issued;

[0021] The baggage sorting process analysis module is used to compare the time difference between the baggage to be analyzed after screening at the baggage analysis start position and the baggage analysis end position with the baggage cycle detection time threshold; if the time difference is greater than the baggage cycle detection time threshold, it is determined that the detection has timed out;

[0022] The baggage circulation detection module is used to obtain detection information of the baggage to be analyzed after screening passing through the baggage circulation detection position when the detection times out, and record the number of times the baggage passes; compare the number of times the baggage passes with the baggage circulation number threshold; if the number of times the baggage passes is greater than the baggage circulation number threshold, issue a circulation timeout alarm;

[0023] The baggage detention detection module is used to compare the current position of the baggage to be analyzed after screening with the early baggage position list. If the current position is in the early baggage position list, compare whether the time difference between the expected flight departure time and the current time is less than the early baggage storage timeout period; if so, issue a baggage detention alarm.

[0024] Furthermore, the baggage tracking, analysis and alarm subsystem further comprises: a baggage sorting abnormality judgment module;

[0025] The baggage sorting anomaly judgment module is used to obtain the time when the baggage to be analyzed last appeared after screening, and compare it with the current time, and based on the time comparison difference, form a baggage sorting anomaly list according to the sorting anomaly category; specifically:

[0026] If the time comparison difference exceeds the first-level threshold, it is judged that the baggage to be analyzed after screening has not arrived at the relevant tracking position in the baggage sorting node position list within the specified time, and a first-level abnormality list is formed at this time;

[0027] If the time comparison difference exceeds the secondary threshold, it is judged that the baggage to be analyzed after screening has not arrived at the baggage analysis end position within the specified time, and a secondary abnormality list is generated at this time;

[0028] If the time comparison difference exceeds the third-level threshold, it is judged that the luggage to be analyzed after screening has abnormal conditions such as lost luggage, dropped luggage, cycle timeout and detained luggage during the sorting process, and a third-level abnormality list is formed at this time.

[0029] Furthermore, the baggage sorting abnormality judgment module further includes: a baggage lost analysis module;

[0030] The lost baggage analysis module is used to perform secondary analysis on the lost baggage in the third-level abnormality list as the target baggage. Specifically, it includes: determining whether the target baggage is a tracking failure baggage or a barcode unread baggage within a corresponding period of time at the next sorting node position;

[0031] If not, it is determined that the target baggage is sorted abnormally, and the sorting abnormality alarm threshold is triggered at this time, and a sorting abnormality alarm is issued.

[0032] If so, the previous baggage and the next baggage of the target baggage at the current position are obtained, and at the next sorting node position, it is detected whether the target baggage is still between the previous baggage and the next baggage; if not, it is determined that the target baggage is stuck or dropped, and the sorting abnormal alarm threshold is triggered at this time, and a sorting abnormal alarm is issued.

[0033] On the other hand, the present invention also provides a baggage tracking, analysis and alarm method for an airport baggage automatic sorting system, characterized in that the method uses the above system and specifically comprises the following steps:

[0041] S22, obtaining the current position of the first baggage to be analyzed, and determining whether the current position of the first baggage to be analyzed is in the analysis exception position list; if so, excluding the corresponding first baggage to be analyzed; if not, determining whether the current position of the first baggage to be analyzed is in the baggage sorting node position list; if not, excluding the corresponding first baggage to be analyzed, and leaving the second baggage to be analyzed;

[0042] S23, determining whether the time when the second luggage to be analyzed leaves the current location is greater than the node location timeout threshold; if not, excluding the corresponding luggage to be analyzed, leaving the third luggage to be analyzed;

[0043] S24, determining whether the third baggage to be analyzed has appeared in the baggage unloading state and the baggage sorting completion state in the baggage handling history information; if so, excluding the corresponding baggage to be analyzed, and the fourth baggage to be analyzed remains;

[0044] S25. Acquire the location information of the fourth baggage to be analyzed from the baggage processing history information. If the location information contains the baggage analysis end location, it is considered that the baggage sorting is normal, and the corresponding baggage to be analyzed is excluded, and the remaining baggage to be analyzed is used as the post-screening baggage to be analyzed.

[0045] Furthermore, the step S3 comprises:

[0046] Check whether the baggage source information is obtained within the baggage source information detection time during the flight period; if not, an alarm of not receiving the baggage source information is issued;

[0047] Compare the time difference between the baggage to be analyzed after screening and the baggage analysis start position and the baggage analysis end position with the baggage cycle detection time threshold; if the time difference is greater than the baggage cycle detection time threshold, it is determined that the detection has timed out;

[0048] In case of the detection timeout, the detection information of the luggage to be analyzed after screening passing through the luggage circulation detection position is obtained, and the number of times the luggage passes is recorded; the number of times the luggage passes is compared with the luggage circulation number threshold; if the number of times the luggage passes is greater than the luggage circulation number threshold, a circulation timeout alarm is issued;

[0049] The current position of the baggage to be analyzed after screening is compared with the early baggage position list. If the current position is in the early baggage position list, compare whether the time difference between the expected flight departure time and the current time is less than the early baggage storage timeout period; if so, a baggage detention alarm is issued.

[0050] Furthermore, the step S3 further includes:

[0051] The last appearance time of the baggage to be analyzed after screening is obtained, and the time is compared with the current time, and based on the time comparison difference, a baggage sorting exception list is formed according to the sorting exception category; specifically:

[0052] If the time comparison difference exceeds the first-level threshold, it is judged that the baggage to be analyzed after screening has not arrived at the relevant tracking position in the baggage sorting node position list within the specified time, and a first-level abnormality list is formed at this time;

[0053] If the time comparison difference exceeds the secondary threshold, it is judged that the baggage to be analyzed after screening has not arrived at the baggage analysis end position within the specified time, and a secondary abnormality list is generated at this time;

[0054] If the time comparison difference exceeds the third-level threshold, it is judged that the luggage to be analyzed after screening has abnormal conditions such as lost luggage, dropped luggage, cycle timeout and detained luggage during the sorting process, and a third-level abnormality list is formed at this time.

[0055] Furthermore, the step S3 further includes:

[0056] The baggage with the abnormal condition of lost baggage in the third-level abnormality list is taken as the target baggage for secondary analysis; specifically, it includes: determining whether the target baggage is a baggage that fails to be tracked or a baggage whose barcode is not read in the corresponding period at the next sorting node;

[0057] If not, it is determined that the target baggage is sorted abnormally, and the sorting abnormality alarm threshold is triggered, and a sorting abnormality alarm is issued;

[0058] If so, the previous baggage and the next baggage of the target baggage at the current position are obtained, and at the next sorting node position, it is detected whether the target baggage is still between the previous baggage and the next baggage; if not, it is determined that the target baggage is stuck or dropped, and the sorting abnormal alarm threshold is triggered at this time, and a sorting abnormal alarm is issued.

[0060] The present invention can timely discover abnormalities in baggage sorting by performing baggage tracking and analysis based on system configuration, which helps to effectively handle abnormal situations and significantly reduce the occurrence of delayed baggage delivery.

[0061] The present invention processes sorting anomalies in a graded manner through a baggage sorting anomaly judgment module, so that baggage system operation and maintenance personnel can understand all current baggage with sorting anomalies and focus on baggage that may cause late delivery; and a list of sorting anomalies can be generated in time during the baggage sorting process, so that baggage system operation and maintenance personnel can check baggage sorting anomaly information at any time.

[0070] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0071] See also Figure 1 As shown, the embodiment of the present invention discloses a baggage tracking analysis alarm system of an airport baggage automatic sorting system, including: a control and information subsystem, a pre-processing subsystem, a baggage tracking analysis alarm subsystem and an alarm server; wherein:

[0072] A control and information subsystem, used to control baggage transportation according to a preset baggage path, configure the system according to the preset baggage path, and obtain system configuration information;

[0073] System configuration information includes: flight time, flight duration, baggage source information detection duration, baggage cycle detection duration threshold, baggage cycle detection position, baggage cycle number threshold, flight baggage analysis start time, flight baggage analysis end time, baggage analysis end status, baggage analysis start position, baggage analysis end position, analysis exception position list, sorting exception category, sorting exception alarm threshold, baggage sorting node position list, node position timeout threshold, early baggage storage timeout duration;

[0074] The pre-processing subsystem is used to screen the baggage to be analyzed based on the system configuration information and obtain the screened baggage to be analyzed;

[0075] The baggage tracking, analysis and alarm subsystem performs baggage tracking and analysis on the baggage to be analyzed after screening based on the system configuration information, and issues an alarm for abnormal analysis results;

[0076] The alarm server is used to process the alarm information.

[0077] The above flight time slots and flight durations are derived from the flight information and flight resource allocation information provided by the baggage handling information (BPM), including flight number, flight date, destination airport, flight status, scheduled departure time, estimated departure time, flight resource number, opening time and closing time, etc.;

[0078] The pre-processing subsystem includes a first non-sorting judgment module, a second non-sorting judgment module, a first sorting normal judgment module, a processing information abnormality judgment module and a second sorting normal judgment module; wherein:

[0079] First, the sorting judgment module is not entered, and it is judged whether the flight is between the start time and the end time of the flight baggage analysis; if not, the corresponding baggage to be analyzed is excluded; if so, it is judged whether the current state of the baggage is in the baggage analysis end state; if so, the corresponding baggage to be analyzed is excluded, and the first baggage to be analyzed remains; by defining the start and end time of the flight baggage analysis and the baggage analysis end state, the baggage of the flight end and the baggage of normal sorting can be excluded, which significantly reduces the number of baggage analysis;

[0080] The second non-sorting judgment module is used to obtain the current position of the first baggage to be analyzed, and judge whether the current position of the first baggage to be analyzed is in the analysis exception position list; if so, the corresponding first baggage to be analyzed is excluded; if not, it is judged whether the current position of the first baggage to be analyzed is in the baggage sorting node position list; if not, the corresponding first baggage to be analyzed is excluded, and the second baggage to be analyzed remains; for example: VIP, CIP, oversized baggage (OOG) or transfer baggage that will not enter the baggage sorting system, these baggage do not need to be sorted, tracked and analyzed; by defining the analysis exception position list and the baggage sorting node position list, the baggage that has not entered the automatic sorting system can be effectively excluded, reducing the number of baggage analyses and the false alarm rate;

[0081] The first sorting normal judgment module is used to judge whether the time when the second baggage to be analyzed leaves the current position is greater than the node position timeout threshold; if not, the corresponding baggage to be analyzed is excluded, and the third baggage to be analyzed remains; by defining the node position timeout threshold, the baggage that is sorted normally can be effectively excluded, further reducing the number of baggage analyses;

[0082] The processing information abnormality judgment module is used to judge whether the third baggage to be analyzed has appeared in the baggage unloading state and the baggage sorting completion state in the baggage processing history information; if so, the corresponding baggage to be analyzed is excluded, and the fourth baggage to be analyzed remains;

[0083] The second normal sorting judgment module is used to obtain the position information of the remaining fourth baggage to be analyzed from the baggage processing history information. If the position information contains the baggage analysis end position, it is considered that the baggage sorting is normal, the corresponding baggage to be analyzed is excluded, and the remaining baggage to be analyzed is used as the baggage to be analyzed after screening; through the second normal sorting judgment module, the baggage history of baggage leaving the node timeout is analyzed, and the baggage that has reached the sorting end position is excluded, so as to eliminate the false alarm situation that the sorting is normal but the baggage processing information is abnormal.

[0084] See also Figure 2 As shown, the above-mentioned baggage tracking analysis alarm subsystem includes: a baggage source information detection module, a baggage sorting process analysis module, a baggage circulation detection module and a baggage detention detection module; wherein:

[0085] The baggage source information detection module is used to detect whether the baggage source information is obtained within the baggage source information detection time during the flight period; if not, it means that the corresponding flight has an abnormal baggage source information, and an alarm of not receiving the baggage source information is issued at this time; wherein, the baggage source information (BSM) is derived from the baggage handling information (BPM), including the baggage barcode number, flight number, flight date, destination airport, event time, check-in counter number and other information;

[0086] The baggage sorting process analysis module is used to compare the time difference between the baggage analysis start position and the baggage analysis end position of the baggage to be analyzed after screening with the baggage cycle detection time threshold; if the time difference is greater than the baggage cycle detection time threshold, it is judged as detection timeout; wherein, the baggage analysis start position and the baggage analysis end position are multiple key nodes for tracking baggage in the baggage tracking analysis alarm system, and RFID technology or related identification technology can be used at these two positions to obtain baggage information, including baggage location, baggage barcode, time, etc.;

[0087] The baggage circulation detection module is used to obtain the detection information of the baggage to be analyzed after screening passing through the baggage circulation detection position in the case of detection timeout, and record the number of times it passes; compare the number of times it passes with the baggage circulation number threshold; if the number of times it passes is greater than the baggage circulation number threshold, a circulation timeout alarm is issued; the baggage circulation detection module can detect the number of times (greater than or equal to 2 times) that the baggage passes through the same position of the sorting line in the baggage tracking and analysis alarm system;

[0088] The baggage detention detection module is used to compare the current position of the baggage to be analyzed after screening with the early baggage position list. If the current position is in the early baggage position list, it compares whether the time difference between the expected departure time of the flight and the current time is less than the early baggage storage (EBS) timeout period; if so, a baggage detention alarm is issued.

[0089] The baggage tracking, analysis and alarm subsystem further includes: a baggage sorting anomaly judgment module, which is used to obtain the last appearance time of the baggage to be analyzed after screening, and compare it with the current time, and based on the time comparison difference, form a baggage sorting anomaly list according to the sorting anomaly category; specifically:

[0090] If the time comparison difference exceeds the first-level threshold, it is determined that the baggage to be analyzed after screening has not arrived at the relevant tracking position in the baggage sorting node position list within the specified time, and a first-level abnormality list is formed at this time; when such abnormal situation occurs, it can be indicated by a blue display light to indicate that the abnormal situation is relatively minor, so such abnormal situation generally does not need to be processed;

[0091] If the time comparison difference exceeds the secondary threshold, it is judged that the baggage to be analyzed after screening has not reached the baggage analysis end position within the specified time, and a secondary abnormality list is formed at this time; when such abnormal situation occurs, it can be indicated by a yellow display light to indicate that the abnormal situation is relatively serious, and the operator needs to continue to pay attention to the sorting status of the baggage;

[0092] If the time comparison difference exceeds the third-level threshold, it is judged that there are abnormal situations such as lost luggage, dropped luggage, cycle timeout and detained luggage in the sorting process of the luggage to be analyzed after screening, and a third-level abnormality list is formed at this time; when such abnormal situation occurs, it can be indicated by a red display light to indicate that the abnormal situation is relatively serious.

[0093] The baggage sorting abnormality judgment module further includes: a baggage lost analysis module, which is used to take the baggage with the abnormality of lost baggage in the third-level abnormality list as the target baggage for secondary analysis; specifically including: judging whether the target baggage is a tracking failure baggage or a baggage with unread barcode in the corresponding time period at the next sorting node position;

[0094] If not, the target baggage is judged to be sorted abnormally, and the sorting abnormality alarm threshold is triggered at this time, and a sorting abnormality alarm is issued to remind the operator to immediately handle the sorting abnormality to ensure that the baggage will not be late;

[0095] If yes, the previous and next baggage of the target baggage at the current location are obtained, and at the next sorting node, it is detected whether the target baggage is still between the previous and next baggage; if not, it is determined that the target baggage is stuck or dropped, and the sorting abnormality alarm threshold is triggered at this time, and a sorting abnormality alarm is issued to remind the operator to immediately handle the sorting abnormality to ensure that the baggage will not be late;

[0096] Based on the lost luggage analysis module, false alarms of lost luggage due to failure to read and loss can be effectively eliminated.

[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 to the baggage tracking analysis alarm subsystem and the alarm server control.

[0113] Compare the time difference between the start position of the baggage analysis and the end position of the baggage analysis of the baggage to be analyzed after screening with the baggage cycle detection time threshold; if the time difference is greater than the baggage cycle detection time threshold, it is judged as detection timeout;

[0114] In case of detection timeout, the detection information of the baggage to be analyzed after screening passing through the baggage circulation detection position is obtained, and the number of times it passes is recorded; the number of times it passes is compared with the baggage circulation number threshold; if the number of times it passes is greater than the baggage circulation number threshold, a circulation timeout alarm is issued;

[0115] The current position of the baggage to be analyzed after screening is compared with the early baggage position list. If the current position is in the early baggage position list, compare whether the time difference between the expected flight departure time and the current time is less than the early baggage storage timeout period; if so, a baggage detention alarm is issued.

[0116] The last appearance time of the baggage to be analyzed after screening is obtained, and the time is compared with the current time, and based on the time comparison difference, a baggage sorting exception list is formed according to the sorting exception category; specifically:

[0117] If the time comparison difference exceeds the first-level threshold, it is judged that the baggage to be analyzed after screening has not arrived at the relevant tracking position in the baggage sorting node position list within the specified time, and a first-level abnormality list is formed at this time;

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

[0131] (4) Compare the current location of the baggage with the analysis exception location list and the baggage sorting node location list of the automatic sorting system. If the current location of the baggage does not belong to the location in the analysis exception location list but belongs to the location in the sorting node list, the baggage tracking is analyzed. Otherwise, no analysis is performed to exclude baggage such as large baggage and VIP baggage that are not in the automatic sorting system.

[0132] (5) Analyze whether the time when the baggage left the current location is greater than the node location timeout threshold. If so, proceed to the next step of analysis; otherwise, do not analyze;

[0133] (6) Analyze whether the baggage handling history information has ever appeared in the baggage unloading state (receiving the baggage deletion BSM report from the departure system and the passenger canceling the baggage check-in) or the baggage analysis end state (after the baggage sorting is completed, the control and information system receives the baggage handling information from the third-party system and the current baggage state is not the baggage analysis end state). If so, no analysis is performed. If not, proceed to the next step of analysis.

[0134] (7) Analyze the location information of the baggage handling history information and compare it with the sorting end location list. If the location information belongs to the location in the sorting end location list, it is considered that the baggage sorting is normal and no analysis is required (for example, the baggage arrives at the manual encoding station and the operator forcibly specifies the sorting). Otherwise, proceed to the next step of analysis;

[0135] (8) Compare the current location of the baggage with the location list of early baggage. If yes, compare whether the estimated departure time of the flight minus the current time is less than the storage timeout period of the early baggage. If yes, set the baggage sorting abnormality level to red and form a baggage sorting abnormality list, and send an early baggage detention alarm to the alarm server; otherwise, judge that the sorting is normal;

[0136] (9) Determine whether the time when the baggage leaves the current location is greater than the first-level threshold (blue level threshold). If so, set the baggage sorting exception level to blue and form a first-level baggage sorting exception list;

[0137] (10) Determine whether the time when the baggage leaves the current location is greater than the secondary threshold (yellow level threshold). If so, set the baggage sorting abnormality level to yellow and generate a secondary baggage sorting abnormality list;

[0138] (11) Whether the time when the baggage leaves the current location is greater than the third-level threshold (red level threshold), if so, the baggage sorting abnormality level is set to red and a third-level baggage sorting abnormality list is formed;

[0139] (12) When the current position of the baggage is not an early baggage position and the baggage sorting abnormality level is red, the baggage tracking failure or unread barcode analysis will be performed to check whether there is any baggage with failed tracking or unread barcode at the corresponding period of the next node position that the baggage should pass through. Then, the previous baggage and the next baggage at the current position of the baggage will be analyzed to check whether they have also passed through the same next node position. Their previous and next positions at the same next node position are the same. If there is no such baggage, a baggage lost alarm will be sent to the alarm server.
