Description

Technical Field

[0001] The present invention belongs to the technical field of airport security inspection, and in particular relates to a baggage inspection control method and system for a security inspection channel. Background Art

[0002] During the airport passenger security check, passengers often leave their tickets, headphones, ID cards and other belongings in the luggage basket after completing the security check, resulting in the loss of passenger belongings. Especially for security check passages with luggage conveyor and recovery devices, when the left-behind items are large, the luggage basket recovery device may not drop the basket into place, resulting in a basket jam, which seriously affects the efficiency of passenger security check. Figure 1 shown.

[0003] At present, airports generally use image acquisition devices to solve the above problems. However, the existing technology only detects whether there are left items in the luggage basket through image acquisition. If there are left items, a prompt message will be output to remind passengers to check for left-behind items, and the luggage box will be re-detected for objects at certain detection cycles until it is detected that there are no objects in the luggage box or the luggage has to be released due to too long a time (otherwise it will affect the security inspection efficiency). However, in the case where passengers come back to look for the left-behind items, the process of passengers looking for and sorting out the left-behind items may take a long time. During this period, the luggage box may be released because the conditions for having to be released are met. Therefore, the luggage box may move during the process of passengers sorting out their luggage, affecting the passenger experience. Summary of the invention

[0004] The object of the present invention is to provide a luggage detection control method and system for a security inspection channel, so as to solve the problem in the prior art that invalid detection of whether there are items in a luggage basket is performed multiple times during the process of passengers searching for and sorting their items, resulting in the reaching of release conditions, thereby causing the luggage basket to move during the process of passengers sorting their luggage.

[0005] In order to solve the above technical problems, the present invention provides a baggage detection control method for a security inspection channel, wherein if an object is detected in a container for placing baggage that has passed through the security inspection measures of the security inspection channel and has been transmitted into a set detection area, a first process is performed; The first process includes: determining whether the human body sensor senses a human body in the set detection area; if not, proceeding to the second process; otherwise, proceeding to the third process; The second process includes: if the number of times of detecting whether there is an object in the container exceeds the re-inspection setting value, the container is released; otherwise, the detection of whether there is an object in the container is repeated at a certain time interval; if it is detected, the first process is carried out; if it is not detected, the container is transported to the set position; The third process includes: stopping the detection of whether there is an object in the container until the human body sensor does not detect a human body within a certain detection cycle, and then performing the second process.

[0006] Furthermore, if no items are detected in the container for placing luggage that has passed the security check measures of the security check channel and is transported into the set area, the container is transported to the set position.

[0007] Furthermore, when the container is released, an alarm signal is triggered at the same time.

[0008] Furthermore, if the human body sensor detects the presence of a human body within a set time after the container is released, the transmission of the container is stopped to wait until the human body sensor does not detect the presence of a human body within a certain detection cycle, and then the container is released again.

[0009] Furthermore, the alarm signal includes a visual alarm signal and an audible alarm signal.

[0010] Furthermore, the release process includes manual release and automatic release.

[0011] Furthermore, the detection of whether there is an object in the container is performed by using a visual detection technology to detect the object in the container.

[0012] Furthermore, transporting the container to a set position is achieved through PLC technology.

[0013] In order to solve the above technical problems, the present invention also provides a security inspection channel baggage detection control system, including a processor, the processor is used to execute a computer program to implement the steps of the security inspection channel baggage detection control method.

[0014] The beneficial effects of the above technical solution are as follows: the present invention provides a new baggage detection control method for a security inspection channel, which detects whether there are passengers in a set detection area by using a human body sensor to find lost items. If the existence of items is detected in a container for placing luggage entering the area and the human body sensor senses a human body, the detection of whether there are items in the container is stopped to wait for the passenger to take the items until the human body sensor does not detect the human body, and then the detection of whether there are items in the container is repeated when the number of re-inspections of the container does not exceed the re-inspection set value. When the number of re-inspections of whether there are items in the container exceeds the re-inspection set value, the container is released, thereby not only using the upper limit of the number of re-inspections as a release condition to promptly deal with the stranded container for placing luggage, but also suspending the re-inspection when the passenger is looking for items, so that there will be no situation in which invalid detection of whether there are items in the luggage basket is performed multiple times during the process of the passenger looking for and sorting the items, resulting in the reaching of the release condition, thereby causing the luggage basket to move during the process of the passenger sorting the luggage.

DETAILED DESCRIPTION

[0016] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0017] Embodiment of baggage detection control method for security inspection channel A baggage detection control method for a security inspection channel of the present embodiment is specifically as follows: when an object is detected in a container for placing baggage that has passed through the security inspection measures of the security inspection channel and has been transferred into a set area, it is determined whether a human body sensor in the set area has detected a human body; if a human body is detected, the detection of whether an object is present in the container is stopped to avoid invalid detection; if no object is detected, the container is re-inspected; if no object is detected in the re-inspection, the container is transferred to a set position; if detected, the detection is repeated until the number of re-inspections exceeds a set value, and the container is released after exceeding the set value; if no object is detected in the container for placing baggage that has passed through the security inspection measures of the security inspection channel and has been transferred into the set area, the container is directly transferred to the set position.

[0018] The baggage detection control method of the security inspection channel specifically includes: If an object is detected in the baggage container that has passed the security inspection measures of the security inspection channel and is transported to the set inspection area, the first process is performed; The first process includes: determining whether the human body sensor senses a human body in the set detection area; if not, proceeding to the second process; otherwise, proceeding to the third process; The second process includes: if the number of times of detecting whether there is an object in the container exceeds the re-inspection setting value, the container is released; otherwise, the detection of whether there is an object in the container is repeated at a certain time interval; if it is detected, the first process is carried out; if it is not detected, the container is transported to the set position; The third process includes: stopping the detection of whether there is an object in the container until the human body sensor does not detect a human body within a certain detection cycle, and then performing the second process.

[0019] Therefore, the baggage detection control method for the security inspection channel of the present embodiment detects whether there are passengers in the set detection area by using the human body sensor to search for lost items. If the existence of items is detected in the baggage container entering the area and the human body sensor senses the human body, the detection of whether there are items in the container is stopped and the passenger is waiting to take the items away until the human body sensor detects no human body. Then, if the number of re-inspections of the container does not exceed the re-inspection set value, the detection of whether there are items in the container is repeated. If the number of re-inspections of whether there are items in the container exceeds the re-inspection set value, the container is released. In this way, the number of re-inspections reaching the upper limit can be used as a release condition, so that the stranded baggage container can be handled in time, and the re-inspection can be suspended when the passenger is looking for the items. Therefore, there will be no situation in which invalid detection of whether there are items in the luggage basket is performed multiple times during the process of the passenger looking for and sorting the items, resulting in the release condition being met, thereby causing the luggage basket to move during the process of the passenger sorting the luggage.

[0020] In this embodiment, the container for placing luggage is a luggage basket (in other embodiments, it may also be other forms of containers, such as a luggage tray, a luggage placement slot, etc., which will not be described in detail here). Specifically, for a luggage basket containing leftover items, the luggage empty basket re-inspection system sets a suitable time to trigger a re-inspection signal according to the passenger traffic volume and the average traffic efficiency, detects and determines whether the passenger is sorting out the leftover items in the luggage basket, and controls the luggage basket image recognition system to re-detect until it is detected that there is no item in the luggage basket or the luggage basket is released.

[0021] The empty baggage basket re-inspection system consists of a human body sensor located at the bottom of the baggage basket conveyor system and a trigger control program. The purpose of the human body sensor is to detect whether there are passengers at the location and provide the system with a suitable re-inspection opportunity. The purpose of the trigger control program is to set the suspicious empty baggage basket re-inspection cycle and the baggage basket disposal logic for lost items. The disposal logic is specifically to release the baggage basket.

[0022] When the empty luggage basket re-inspection system detects that a passenger is packing personal belongings, there is no need to inspect the luggage basket with the left items. When the passenger leaves this area, the human body sensing sensor cannot detect the human body signal, and the photoelectric sensor that detects the luggage basket in place signal still has a signal. At this time, the re-inspection signal is triggered according to the re-inspection cycle and disposal logic, and the luggage basket image is re-collected for re-inspection.

[0023] In this embodiment, if no items are detected in the container for placing luggage that has passed the security inspection measures of the security inspection channel and is transported into the set area, the container is transported to the set position.

[0024] Specifically, the empty luggage baskets are transported by the luggage basket transmission control system to a luggage basket collection area or an empty basket recovery and loading device of the intelligent passenger security inspection system.

[0025] In this embodiment, when the container is released, an alarm signal is triggered at the same time. The alarm signal includes a visual alarm signal and an audio alarm signal, the visual alarm signal is such as a flashing alarm signal, and the audio alarm signal is such as a buzzer alarm signal. The release process includes manual release and automatic release.

[0026] Specifically, when the number of re-inspections reaches a certain number, an alarm signal is triggered, and the PLC transmission control system controls the flashing of the alarm and the buzzer alarm; when the luggage basket handling logic (i.e. the processing logic of the release process) is automatic release, the re-inspection system automatically releases the luggage basket that has been detected to have left; when the luggage basket handling logic is manual release, the security staff manually presses the release switch to release them one by one.

[0027] In this embodiment, if the human body sensor detects the presence of a human body within a set time after the container is released, the transmission of the container is stopped to wait until the human body sensor does not detect the presence of a human body within a certain detection cycle, and then the container is released again.

[0028] Specifically, after releasing the luggage basket, if the human body detects that the passenger receives an alarm signal and searches for the luggage, the PLC transmission control system stops transmitting the luggage basket, waits for the passenger to search and organize the luggage, and continues to release the container after the passenger leaves.

[0029] In this embodiment, the detection of whether there are items in the container is performed by visual detection technology. Specifically, the visual detection technology can determine whether there are items left in the luggage basket and mark the outline of the items in the basket. This technology belongs to the existing technology and will not be described here. After the luggage basket image is detected, the detection result will be fed back to the PLC transmission control system.

[0030] In this embodiment, transporting the container to the set position is achieved through PLC technology.

[0031] Specifically, the PLC conveying control system using PLC technology controls and starts the conveyor belt where the current baggage basket is located, ensuring that the empty baggage basket reaches the collection area or smoothly enters the baggage basket recovery device (ie, the set position).

[0032] The specific implementation steps are as follows: Step 1: At the baggage basket collection point at the end of the security inspection channel transmission system, install a photoelectric sensor and an identity reader at the identification position of the baggage basket to be collected, connect the photoelectric sensor and the identity reader to the transmission control system PLC, and ensure that the baggage basket blockage signal and identity recognition information can be captured by the PLC. When the baggage basket passes through the X-ray machine and completes the security inspection, the end of the baggage basket transmission system (for the baggage basket collection point) is stationary. When the baggage basket reaches the end of the transmission system, it stops and blocks the photoelectric sensor. At this time, the photoelectric sensor generates a baggage basket blockage signal, which is then captured by the PLC and sent to the baggage basket image acquisition system.

[0033] In this embodiment, the identity reader is an RFID reading system, which is mainly applicable to the scenario where the luggage basket has an identity tag, and can obtain the specific luggage basket identity information and provide further image detection strategies in a targeted manner; Figure 3 shown.

[0034] Step 2: Install image acquisition and fill-light equipment at the identification position above the luggage basket collection point, deploy the corresponding control program, and connect the image acquisition system to the PLC; after the transmission control system receives the luggage basket in place signal, it sends an image acquisition instruction to the luggage basket image acquisition system to perform luggage basket image acquisition.

[0035] The luggage basket image acquisition system is mainly composed of a high-definition camera, a fill light unit, and a mounting bracket. Its purpose is to collect complete and clear luggage basket images under different lighting conditions and provide a data source for the image recognition system. Its function is to provide stable and clear image quality, design a time domain fill light method, automatically adjust the illumination according to the time period, and turn on the high-definition camera autofocus function to ensure the image quality of the image acquisition system at different installation heights.

[0036] Step 3: The luggage basket image recognition system receives the luggage basket image collected by the image acquisition system, and recognizes the image in real time through the luggage basket image detection method based on time period matching and positioning, marks the outlines of the items in the luggage basket, and feeds the recognition results back to the transmission control system PLC. The image recognition system uses visual detection technology to detect the luggage basket image, determine whether there are any leftover items in the luggage basket, and mark the outlines of the items in the basket. The specific detection results are as follows: Figure 4 shown.

[0037] For the airport passenger security luggage empty basket detection system equipped with an identity recognition device, multiple groups of image feature matching templates can be configured for luggage basket IDs with significant features or high false alarm rates to improve their detection accuracy.

[0038] Step 4: The conveying control system receives the detection result. If there is no item in the bag, it immediately controls the bag conveying system to start, and conveys the empty bag to the collection area or connects to the bag recovery system and sends it to the bag collection device.

[0039] The transmission control system is used to control the start and stop of luggage basket transmission, the linkage control of the luggage basket image acquisition system, and the docking control with the empty basket recovery device of the intelligent passenger security inspection system. First, the transmission control system PLC can capture the luggage basket identity information and arrival signal generated by the photoelectric sensor, and feed the arrival signal back to the luggage basket image acquisition system; second, it can control the start and stop of the conveyor belt end according to the detection results of the image recognition system; third, it can control the start and stop of the empty basket transmission according to the plate drop signal of the empty basket recovery device of the intelligent passenger security inspection system.

[0040] Step 5: For luggage baskets with leftover items detected, the empty luggage basket re-inspection system sets an appropriate time to trigger a re-inspection signal based on the passenger traffic volume and average traffic efficiency, and determines whether the passenger is sorting out the leftover items in the luggage basket. If the passenger is sorting out the items, the system enters a waiting state. Otherwise, the luggage basket re-inspection subsystem will trigger a signal periodically to enable the luggage basket image acquisition system to re-capture images and re-detect through the luggage basket image recognition system until it is detected that there are no items in the luggage basket or the luggage basket identity recognition system cannot detect the position of the luggage basket.

[0041] When the number of re-inspections reaches a certain number, an alarm signal is triggered, and the PLC transmission control system controls the flashing of the alarm and the buzzer alarm; when the luggage basket handling logic is automatic release, the re-inspection system automatically releases the luggage basket that has been detected to have left by the passenger; when the luggage basket handling logic is manual release, the security staff manually presses the release switch to release the luggage baskets in turn. During manual release or automatic release, if the human body sensing sensor senses a passenger, the PLC controls the basket to stop and wait until the human body sensing sensor no longer senses a passenger, and then the luggage basket continues to be released. The specific process is as follows Figure 2 As shown, the specific architecture is as follows Figure 5 shown.

[0042] When the image recognition system encounters a failure or recognition error, it can be configured in manual detection mode, manually triggering the image recognition acquisition system to re-inspect the current baggage basket, and operating the empty basket transfer control button to control the forward or backward transfer of the baggage basket.

[0043] The present invention realizes the transmission and detection of luggage baskets through the cooperation of PLC technology and visual detection technology, and further provides a human body sensing sensor for detecting whether there are passengers looking for lost items. If items are detected in the luggage baskets in the set area and the human body sensor senses the passenger, the detection of whether there are items in the luggage baskets is stopped and the passenger is waited for to take the items until the human body sensor detects no passenger. If the number of re-inspections of the luggage baskets does not exceed the re-inspection set value, the luggage baskets are repeatedly inspected. If the number of re-inspections of the luggage baskets exceeds the re-inspection set value, the container is released, which solves the problem of invalid detection of whether there are items in the luggage baskets for many times in the process of passengers looking for and sorting out items in the prior art.

[0044] Security inspection channel baggage detection control system embodiment The present invention also provides a security inspection channel baggage detection control system, including a processor, the processor is used to execute a computer program to implement the steps of the security inspection channel baggage detection control method. The specific process, principle and effect have been described in detail in the embodiment of the security inspection channel baggage detection control method, and will not be repeated here.

[0045] Specific implementation methods are given above, but the present invention is not limited to the described implementation methods. The basic idea of ​​the present invention lies in the above basic scheme. For ordinary technicians in this field, it does not take creative work to design various deformed models, formulas, and parameters according to the teachings of the present invention. Changes, modifications, substitutions, and variations of the implementation methods without departing from the principles and spirit of the present invention still fall within the scope of protection of the present invention.
