Description

Technical Field

[0001] The present invention relates to the technical field related to dynamic task allocation for centralized image judgment for security inspection, and in particular to a method, system, device and storage medium for dynamic task allocation for centralized image judgment for security inspection. Background Art

[0002] In rail transit, airports, passenger transport, logistics and many other fields, the use of intelligent X-ray security inspection equipment to intelligently identify luggage, parcels and passenger carry-on items and discover potential security risks has become an indispensable part of ensuring public safety. Traditional security inspections often use a local image judgment mode. In order to reduce security inspection costs and improve security inspection efficiency, a new security inspection mode based on centralized image judgment has gradually emerged, becoming an effective supplement to the local image judgment mode of security inspection, and has played a great role in improving the efficiency of security inspection image judgment personnel and reducing labor costs.

[0003] The existing centralized image judgment task allocation method for security inspection often only considers the single-center centralized scheduling mode, which mainly considers the dynamic allocation of tasks among different centralized image judgment seats after receiving the image judgment tasks from each security inspection point. In this scenario, it is often assumed that the network bandwidth can meet the reporting requirements of security inspection image information of all security inspection points and the distribution requirements of centralized image judgment results, and the centralized image judgment scheduling service has sufficient computing power to meet the timeliness requirements of image judgment. In reality, the use of this single-center scheduling mode may produce performance bottlenecks, poor fault tolerance, and lack of detection of the timeliness of tasks to be judged. It is unable to cope with the problems of low efficiency in processing tasks to be judged and security inspection quality of key sites when real-time traffic changes sharply. Summary of the invention

[0004] The present invention aims to at least solve the technical problems existing in the prior art. To this end, the present invention proposes a method, system, device and storage medium for dynamic task allocation of centralized image judgment for security inspection, which can cope with the situation where the number of tasks to be judged increases rapidly when the passenger flow increases suddenly, and improves the efficiency of processing tasks to be judged and the quality of security inspection.

[0007] According to the target pre-allocation scheme, the task to be judged is allocated to the judgment seat in the dispatching center corresponding to the target pre-allocation scheme for judgment, and a judgment result is obtained; wherein the generation process of any pre-allocation scheme includes:

[0008] Obtaining the first historical package flow data of each security checkpoint in the period;

[0067] In the description of the present invention, it should be noted that, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0068] In rail transit, airports, passenger transport, logistics and many other fields, the use of intelligent X-ray security inspection equipment to intelligently identify luggage, parcels and passenger carry-on items and discover potential security risks has become an indispensable part of ensuring public safety. Traditional security inspections often use a local image judgment mode. In order to reduce security inspection costs and improve security inspection efficiency, a new security inspection mode based on centralized image judgment has gradually emerged, becoming an effective supplement to the local image judgment mode of security inspection, and has played a great role in improving the efficiency of security inspection image judgment personnel and reducing labor costs.

[0069] The existing method for allocating centralized image judgment tasks for security inspections often only considers a single-center centralized scheduling mode, which mainly considers the dynamic allocation of tasks among different centralized image judgment seats after receiving the image judgment tasks from each security inspection point. In this scenario, it is often assumed that the network bandwidth can meet the reporting requirements of security inspection image information at all security inspection points and the distribution requirements of centralized image judgment results, and that the centralized image judgment scheduling service has sufficient computing power to meet the timeliness requirements of image judgment. In reality, the use of this single-center scheduling mode may produce performance bottlenecks, poor fault tolerance, and lack of detection of the timeliness of tasks to be judged; it is unable to cope with the rapid changes in real-time traffic, resulting in low efficiency in processing tasks to be judged and security inspection quality problems at key sites.

[0070] In order to solve the above technical defects, the embodiments of the present application provide a method, system, device and storage medium for dynamic task allocation of centralized image judgment for security inspection.

[0071] See also Figure 1 , is a flow chart of a method for dynamic task allocation of centralized image judgment for security inspection provided in an embodiment of the present application. The method is applied to a controller, which may be a server, an electronic device, or a mobile terminal, etc., which is not specifically limited here. The method includes the following steps S101 to S102.

[0072] Step S101, obtain the target security checkpoint corresponding to the task to be judged and the target time period when the task to be judged is generated, and determine the corresponding target pre-allocation plan according to the target security checkpoint and the target time period; the target time period is one of the multiple time periods divided into daily time periods within the cycle; the target pre-allocation plan is one of the preset multiple pre-allocation plans, and each time period corresponds to a pre-allocation plan.

[0073] Step S102: according to the target pre-allocation scheme, the image judgment task is assigned to the image judgment seat in the dispatching center corresponding to the target pre-allocation scheme for image judgment, and the image judgment result is obtained; wherein the generation process of any pre-allocation scheme includes:

[0074] Obtain the first historical package flow data of each security checkpoint within the period;

[0075] Determine a first allocation scheme according to the first historical package flow data, wherein the first allocation scheme is used to indicate the dispatch center corresponding to each security checkpoint allocated every day within a period;

[0076] Obtain the first quality level of the image judge, the second historical package flow data of each security checkpoint in each time period in the dispatch center, and the first danger level of each security checkpoint, and determine a second allocation plan, wherein the second allocation plan is used to indicate the image judgement seat corresponding to each security checkpoint in the dispatch center in each time period;

[0077] According to the first allocation scheme and the second allocation scheme, a preliminary allocation scheme is obtained.

[0078] The following is an explanation of step S101:

[0079] The cycle can be set according to specific needs, which can be one day, one week or one month, etc., and each day can be divided into multiple time periods according to specific needs. For example, a day can be divided into morning peak time period, off-peak time period and evening peak time period according to package flow data, etc., or divided by hours, such as every three hours as a time period. The pre-allocation plan is determined in advance based on historical flow package data and security inspection related information. When the target security checkpoint information corresponding to the task to be judged and the target time period when the task to be judged is generated are obtained, the target security checkpoint information and the target time period are matched with the pre-allocation plan to determine the target pre-allocation plan, and the task to be judged is allocated to the corresponding judgment seat in the corresponding dispatch center for judgment through the target pre-allocation plan.

[0080] The following is an explanation of step S102:

[0081] The first historical parcel flow data is the historical parcel flow data of each security checkpoint every day within the period. The security checkpoint that each dispatching center is responsible for on the corresponding date is determined based on the weighted average value of the historical parcel flow data of each security checkpoint every day, that is, the first allocation plan, so that the tasks to be judged received by each dispatching center every day tend to be balanced.

[0082] The second historical parcel flow data is the historical parcel flow data of the security check point in each time period on the corresponding date. Through the second historical parcel flow data, the first danger level of the security check point and the first quality level of the judge, an allocation plan for the corresponding judge seats in the corresponding dispatch center for each time period is generated, that is, the second allocation plan.

[0083] In the specific implementation, according to the first allocation scheme, the tasks to be judged are transmitted to the corresponding dispatching center, and the dispatching center maintains a task load list L=[L1, L2, ... , L N ], N is the total number of seats corresponding to the image judgment, L1, L2, ..., L N The initial value of each day is zero. It increases by 1 for each image judgment task received and decreases by 1 after processing a image judgment task. When the dispatch center receives an image judgment task to be judged, it first identifies the first danger level of the security checkpoint corresponding to the image judgment task, traverses the task load list L, and sorts the corresponding image judgment seats that have not reached the saturation interval according to the quality level of the judges on the image judgment seats. Image judgment tasks with higher danger levels of the target security checkpoints corresponding to the image judgment tasks are preferentially allocated to image judgment seats with higher image judgment quality levels. At the same time, continuous allocation to the same image judgment seat is avoided during the allocation process.

[0084] In some embodiments, before the image tasks to be judged are allocated according to the target pre-allocation plan, the timestamps of the received image tasks to be judged are counted, and for the image tasks to be judged that exceed the preset time, the corresponding image task number to be judged and the security inspection-related information of the image tasks to be judged are recorded, and the image tasks to be judged are no longer allocated; if the number of image tasks to be judged that time out at a security check point exceeds the set threshold within a preset period, the security check point will be notified to switch to the local image judgment mode, and the image tasks to be judged will no longer be reported to the dispatch center for centralized image judgment; if the load information in the task load list L of the image judgment seat is not updated within the preset time, the image judgment seat will be recorded and alarmed, and the image judgment seat will be included in the abnormal seat list, and the assignment of image tasks to be judged to the seat will be stopped until the manual inspection is reset and the image tasks to be judged are assigned again.

[0085] It should be noted that the preset duration, preset cycle, set threshold and preset time can all be set according to actual conditions.

[0086] In some embodiments, after the image judging seat completes the image judging, it will feed back the image judging result to the corresponding dispatching center, the dispatching center will feed back the image judging result to the corresponding security checkpoint, the security checkpoint will record the image judging result and transmit it to the master control center and cloud server for storage.

[0087] In some implementations, when the master control center detects that a dispatch center fails, the pending map tasks of the dispatch center may be transferred to other dispatch centers to avoid the problem of failure of a single dispatch center.

[0088] The method generates a first allocation plan by pre-acquiring the first historical package flow data of all security checkpoints within a cycle every day, and dynamically allocates the security checkpoints that each dispatching center is responsible for every day through the first allocation plan, so that the number of target pending image tasks received by each dispatching center every day tends to be balanced, thereby improving the efficiency of centralized processing of pending image tasks and the traffic efficiency of pending image tasks; and generates a second allocation plan through the second historical package flow data of each security checkpoint in each time period every day, the first danger level of each security checkpoint and the danger level of all image judges, and dynamically allocates the target pending image tasks of each security checkpoint in each time period every day to the corresponding image judging seats in the corresponding dispatching center for image judging, so as to ensure that the target pending image tasks allocated to the corresponding image judging seats of each dispatching center in different time periods tend to be balanced, and prevent the image judgment failure caused by the sudden increase in passenger flow and the problem that the pending image tasks cannot be processed in time due to congestion, and at the same time, make the image judges with high quality levels responsible for the security checkpoints with high danger levels to the greatest extent, thereby improving the safety and accuracy of processing pending image tasks; finally, a pre-allocation plan is generated through the first allocation plan and the second allocation plan. When a task to be judged is received, the target security checkpoint corresponding to the task to be judged and the target time period when the task to be judged is generated are obtained, and the corresponding target pre-allocation plan is determined according to the target security checkpoint and the target time period. The task to be judged can be evenly allocated to the corresponding dispatching center and the corresponding image judgment seat, thereby effectively alleviating the load of task reception and task dispatching of each dispatching center, effectively avoiding the single point failure problem caused by network failure or dispatching center failure, and greatly improving the processing efficiency of the task to be judged.

[0089] In some embodiments, before determining the first allocation plan according to the first historical package flow data in step S102, the method further includes the following step S201.

[0090] Step S201: Calculate the weighted average of the first historical parcel flow data of each security checkpoint on the corresponding date. The weighted average of the first historical parcel flow data is calculated in the following manner:

[0091] ;

[0092] ;

[0093] ;

[0094] in, For security checkpoint i On Date d The weighted average of the first historical package flow data, , is the weight parameter, For the front n Monthly security checkpoint i On Date d The average value of the first historical package flow data, For the front Security checkpoint i On Date d The average value of the first historical package flow data, The historical years for statistics.

[0095] Wherein, determining the first allocation scheme according to the first historical package flow data in step S102 includes the following step S202.

[0096] Step S202: Determine a first allocation plan based on a weighted average of the first historical package flow data.

[0097] In this embodiment, , It can also be manually set according to actual needs. The larger the value, the more emphasis is placed on the data of recent months. The larger the value, the more emphasis is placed on empirical data for the same date in the historical year.

[0098] In this embodiment, the corresponding date of each security checkpoint is calculated. d The weighted average of the first historical package flow data, according to the corresponding date of each security checkpoint d The weighted average of the first historical package flow data of the corresponding date is obtained d The first allocation plan for the security checkpoints that each dispatching center is responsible for makes the sum of the weighted average values ​​of the first historical package flow data of the security checkpoints that each dispatching center is responsible for approximately equal, thereby ensuring that the number of tasks to be judged received by each dispatching center tends to be balanced, thereby improving the efficiency of centralized processing of tasks to be judged and the traffic efficiency of tasks to be judged.

[0099] In some embodiments, obtaining the danger level of each security checkpoint in step S102 includes the following step S301.

[0100] Step S301: Calculate the danger level of each security checkpoint using the following formula:

[0101] ;

[0102] in, For security checkpoint j The danger level, , is the weight parameter, For security checkpoint j The number of images judged as dangerous within the preset time. For security checkpoint j The total number of target image tasks received within the preset time. It is the maximum number of target waiting-for-judgment tasks received by all security checkpoints within the preset time.

[0103] Specifically, in this embodiment, by calculating the danger level of each security check point, image judges of corresponding quality levels can be assigned to perform image judgment according to the danger level of the security check, so as to improve the image judgment quality.

[0104] In some embodiments, before obtaining the first quality grade of the judges, the second historical package flow data of each security checkpoint in each time period in the dispatch center, and the first danger grade of each security checkpoint in step S102 and determining the second allocation plan, the method further includes the following step S401.

[0105] Step S401: Calculate the first quality grade of the image judge. The first quality grade of the image judge is calculated in the following way:

[0106] ;

[0107] in, For judges i The first quality level, , is the weight parameter, For judges i Identify the quantity of dangerous goods at a preset time, The maximum number of dangerous objects that all judges can identify within the preset time. For judges i Correctly identify the quantity of hazardous materials at the preset time.

[0108] The process of obtaining the first quality level of the judges, the second historical package flow data of each security checkpoint in each time period in the dispatching center, and the first danger level of each security checkpoint in step S102 and determining the second allocation plan includes the following steps S402 to S403.

[0109] Step S402: Determine the number of image judgment seats corresponding to each security check point in each time period according to the second historical package flow data of each security check point in each time period in the dispatching center.

[0110] Step S403, assigning the judges to corresponding judging seats according to the first quality level of the judges, the first danger level of each security checkpoint in the dispatching center, and the number of judging seats corresponding to each security checkpoint in each time period to obtain a second allocation plan.

[0111] In this embodiment, , Preset according to actual situation. The larger the value, the more emphasis is placed on the image judge's image recognition efficiency. The larger the value, the more emphasis is placed on the accuracy of the judges in identifying dangerous objects.

[0112] In this embodiment, the number of image judgment seats at the security check point is first allocated based on the second historical parcel flow data of each time period at the security check point that the dispatch center is responsible for, and then based on the first danger level of the security check point, the judges corresponding to the first quality level are assigned to the corresponding image judgment seats to judge the image tasks received by the security check point.

[0113] In this embodiment, based on the second historical parcel flow data of each security checkpoint in each time period in the dispatching center, the first danger level of each security checkpoint and the first quality level of the judges, a second allocation plan for the corresponding judgement seats of each security checkpoint in different time periods is generated for multiple dispatching centers, so that the number of images to be judged processed by each judgement seat of the dispatching center in the same time period is approximately equal, so as to achieve the effect of balancing the judgement tasks allocated to the corresponding judgement seats of each dispatching center in different time periods, and all judges are allocated to the corresponding judgement seats in the corresponding dispatching centers according to the danger level of each security checkpoint, so as to ensure that the judges with high quality levels are responsible for the security checkpoints with high danger levels to the greatest extent, thereby increasing the detection rate of safety hazards and improving the quality of image judgment.

[0114] In some embodiments, before obtaining the target security checkpoint corresponding to the task to be judged and the target time period at which the task to be judged is generated in step S101 and determining the corresponding target pre-allocation plan according to the target security checkpoint and the target time period, the method further includes the following step S501.

[0115] Step S501: preset a maximum load factor, which is calculated in the following way:

[0116] ;

[0117] ;

[0118] in, is the maximum load factor, is an adjustable parameter, The maximum number of target image tasks that a single image judgment seat can process per minute. is the number of all judges, is the number of all security checkpoints.

[0119] Among them, in step S101, the target security checkpoint corresponding to the task to be judged and the target time period when the task to be judged is generated are obtained, and the corresponding target pre-allocation plan is determined according to the target security checkpoint and the target time period, including the following steps S502 to S503.

[0120] Step S502: Determine whether the number of target pending tasks at the target security checkpoint is less than the maximum load factor during the target time period.

[0121] Step S503: When the number of target pending tasks of the target security checkpoint is less than the maximum load factor, a corresponding target pre-allocation scheme is determined according to the target security checkpoint and the target time period.

[0122] In this embodiment, a maximum load factor is set, and the number of target image tasks to be judged at the security checkpoint is compared with the maximum load factor at preset intervals. When the number of target image tasks to be judged at the security checkpoint is greater than the maximum load factor, the image judgment mode of the security checkpoint is changed to the local image judgment mode during the time period, and the target image tasks to be judged at the security checkpoint are not uploaded to the dispatching center; when the number of target image tasks to be judged at the security checkpoint is less than the maximum load factor, the target image tasks to be judged at the security checkpoint are allocated to the corresponding image judgment seats of the corresponding dispatching center for image judgment according to the target pre-allocation plan.

[0123] In this embodiment, by setting the maximum load factor, the pressure on the centralized image judgment room can be effectively alleviated when the passenger flow suddenly increases, avoiding congestion and delay in the centralized processing of the tasks of waiting to be judged, thereby improving the real-time efficiency of processing the tasks of waiting to be judged, and improving the traffic efficiency of the security inspection channel.

[0124] In some embodiments, in step S102, according to the target pre-allocation scheme, the image judgment task is allocated to the image judgment seat in the dispatching center corresponding to the target pre-allocation scheme for image judgment. After the image judgment result is obtained, the method further includes the following steps S601 to S605.

[0125] Step S601: Update the first historical package flow data according to the image judgment result to obtain the third historical package flow data.

[0126] Step S602: Adjust the first allocation plan according to the third historical package flow data.

[0127] Step S603: Update the second historical parcel flow, the first quality level of the judge and the first danger level of the security checkpoint according to the judgment result, and obtain the fourth historical parcel flow data, the second quality level of the judge and the second danger level of the security checkpoint.

[0128] Step S604: Adjust the second allocation plan according to the fourth historical package flow data, the second quality level of the map judges and the second danger level of the security checkpoint.

[0129] Step S605: Adjust the pre-allocation plan according to the adjusted first allocation plan and the adjusted second allocation plan.

[0130] In this embodiment, after the image judgment result is obtained, the image judgment result is integrated with the first historical parcel flow data to obtain the third historical parcel flow data. At the same time, the image judgment result is integrated with the second historical parcel flow data to obtain the fourth historical parcel flow data, and the first quality level of the image judge and the first danger level of the security check point are updated to obtain the second quality level of the image judge and the second danger level of the security check point. By updating the above data, the adjusted first allocation plan and the second allocation plan are obtained to obtain a new pre-allocation plan.

[0131] In this embodiment, real-time adjustment and update are performed through the pre-allocation plan, and at the next corresponding date and time period, the flow change and the update of quality and hazard level can be responded to in time to ensure the efficiency and safety of package processing.

[0132] In some embodiments, after the pre-allocation scheme is adjusted according to the adjusted first allocation scheme and the adjusted second allocation scheme in step S605, the method further includes the following step S701.

[0133] Step S701: Upload the adjusted pre-allocation plan to the master control center and store it in the cloud server, wherein the master control center is used to control the dispatching center.

[0134] In this embodiment, the adjusted pre-allocation scheme is sent to the master control center via a secure network link, and the adjusted pre-allocation scheme is stored in a cloud server, which has high availability and redundant storage to ensure data security and accessibility.

[0135] In this embodiment, by uploading the pre-allocation plan in real time, the main control center can obtain the latest pre-allocation plan in real time, and control and manage the dispatch center according to the pre-allocation plan to ensure smooth allocation of the pending image tasks of the security checkpoints.

[0137] The task acquisition module 1100 is used to obtain the target security checkpoint corresponding to the task to be judged and the target time period at which the task to be judged is generated, and determine the corresponding target pre-allocation scheme according to the target security checkpoint and the target time period; the target time period is one of the multiple time periods divided into daily time periods within the cycle; the target pre-allocation scheme is one of the preset multiple pre-allocation schemes, and each time period corresponds to a pre-allocation scheme;

[0138] The dynamic allocation module 1200 is used to allocate the image judgment tasks to the image judgment seats in the dispatching center corresponding to the target pre-allocation scheme according to the target pre-allocation scheme for image judgment to obtain the image judgment result; wherein the generation process of any pre-allocation scheme includes:

[0139] Obtain the first historical package flow data of each security checkpoint within the period;

[0140] Determine a first allocation scheme according to the first historical package flow data, wherein the first allocation scheme is used to indicate the dispatch center corresponding to each security checkpoint allocated every day within a period;

[0141] Obtain the first quality level of the image judge, the second historical package flow data of each security checkpoint in each time period in the dispatch center, and the first danger level of each security checkpoint, and determine a second allocation plan, wherein the second allocation plan is used to indicate the image judgement seat corresponding to each security checkpoint in the dispatch center in each time period;

[0142] According to the first allocation scheme and the second allocation scheme, a preliminary allocation scheme is obtained.

[0143] The system generates a first allocation plan by pre-acquiring the first historical package flow data of all security checkpoints within a cycle every day, and dynamically allocates the security checkpoints that each dispatching center is responsible for every day through the first allocation plan, so that the number of target pending image tasks received by each dispatching center every day tends to be balanced, thereby improving the efficiency of centralized processing of pending image tasks and the traffic efficiency of pending image tasks; and generates a second allocation plan through the second historical package flow data of each security checkpoint in each time period every day, the first danger level of each security checkpoint, and the danger level of all image judges, and dynamically allocates the target pending image tasks of each security checkpoint in each time period every day to the corresponding image judging seats in the corresponding dispatching center for image judgment, so as to ensure that the target pending image tasks allocated to the corresponding image judging seats of each dispatching center in different time periods tend to be balanced, prevent the image judgment failure caused by the sudden increase in passenger flow and the problem that the pending image tasks cannot be processed in time due to congestion, and at the same time make the high-quality image judges responsible for the security checkpoints with high danger levels to the greatest extent, thereby improving the safety and accuracy of processing pending image tasks; finally, a pre-allocation plan is generated through the first allocation plan and the second allocation plan. When a task to be judged is received, the target security checkpoint corresponding to the task to be judged and the target time period when the task to be judged is generated are obtained, and the corresponding target pre-allocation plan is determined according to the target security checkpoint and the target time period. The task to be judged can be evenly allocated to the corresponding dispatching center and the corresponding image judgment seat, thereby effectively alleviating the load of task reception and task dispatching of each dispatching center, effectively avoiding the single point failure problem caused by network failure or dispatching center failure, and greatly improving the processing efficiency of the task to be judged.
