Description

Technical Field

[0001] The present invention relates to the technical field of airport crossing security inspection, and in particular to a remote centralized image judgment method and a system thereof applied to airport crossing security inspection. Background Art

[0002] Airport security check refers to the security check of all passengers, staff and visitors entering the security control area at each entrance of the airport. At the same time, the items brought by passengers, staff and visitors into the airport security control area must be subject to X-ray or manual inspection to ensure that no prohibited or dangerous items are carried.

[0003] The importance of airport checkpoint security lies in ensuring the safe operation of the airport and the travel safety of passengers. Through strict security inspection measures, dangerous goods can be effectively prevented from entering the airport and security risks can be reduced. In addition, the airport checkpoint security management regulations also emphasize the training and management of security personnel to ensure that they have professional security inspection skills and knowledge and can accurately identify and deal with various security threats.

[0004] In fact, the security personnel in the airport checkpoint security also include image judges, who judge the items passing through the checkpoint security X-ray machine for prohibited or dangerous items to ensure that there are no prohibited or dangerous items in the items passing through the airport security checkpoint. In the traditional airport checkpoint security checkpoint, each airport checkpoint needs to correspond to an image judge. Therefore, after a long period of checkpoint security work, the inventor of our company found the following technical problems:

[0005] 1. At our company's Jiangbei Airport, T2A Arrival, T2B Arrival, T3A Domestic Arrival, T3A International Arrival and other commonly used crossings, as well as construction crossings and emergency crossings, all need to undergo map-based security checks. However, our company's Jiangbei Airport is built in the mountainous area of ​​Chongqing, which makes the above-mentioned crossings far apart, and all crossings are scattered and widely distributed, and each crossing security inspection work area operates independently. Therefore, each crossing security inspection requires at least 5 security inspectors, which increases the labor cost of Jiangbei Airport;

[0006] 2. Based on the above technical problems, since the above-mentioned intersections are located far apart and all the intersections are scattered and widely distributed, the security personnel and map judges cannot communicate with each other in real time, resulting in poor information flow between intersections and inability to centrally manage all intersections;

[0007] 3. Based on the above technical problems, due to the poor information flow between the checkpoints, it is impossible to centrally manage all the checkpoints. At the same time, our company's Jiangbei Airport usually encounters peak hours, off-peak hours and night hours. During peak hours, the flow of passengers, staff and visitors at some checkpoints increases, which may easily lead to security personnel being unable to timely identify items as contraband or dangerous goods. Although other checkpoints are in peak hours, the flow of passengers, staff and visitors is small, and the workload of security personnel is not large. Therefore, in order to solve the unequal workload of security personnel during the above peak hours, security personnel with less workload will be deployed. However, since the distribution locations of various checkpoints are far apart and all the checkpoints are scattered and widely distributed, it is difficult to achieve real-time deployment, and the human resource cost is also greatly increased. Summary of the invention

[0008] The present invention aims to provide a remote centralized image judgment method and system for airport crossing security inspection, which can realize centralized management of all crossings, rationally allocate human resources in real time, streamline positions, and reduce labor costs.

[0009] In order to achieve the above object, the present invention adopts the following technical scheme:

[0010] 1) A remote centralized image recognition method applied to airport crossing security inspection includes the following steps:

[0011] Step S1, each road crossing security inspection work area is set with a package opening unit for obtaining a package opening image, and the package opening units of all road crossing security inspection work areas are connected to a picture judgment unit, and the picture judgment unit is connected with the package opening units of each road crossing security inspection work area to form a picture judgment channel, each picture judgment channel corresponds to a matching management unit, and the data of all management units are summarized in the picture judgment unit;

[0012] Step S2, setting each road crossing security inspection work area as unmanned, with image judgment units corresponding to different image judgment channels, and automatically dispatching to the image judgment channel with matching inspection volume according to the inspection volume of the image judgment channel, while other image judgment channels are "idle";

[0013] Step S3: the image judging unit performs image judging on the image judging channel that matches the inspection quantity, and transmits the image judging result to the management unit corresponding to the image judging channel, and the management unit will start the early warning inspection of the unpacking unit.

[0014] Compared with the prior art, the present technical solution adopts a centralized image judgment structure, in which the unpacking unit of each checkpoint security inspection forms an independent image judgment channel with the image judgment unit respectively, and all independent image judgment channels are centrally controlled by the image judgment unit to realize real-time and accurate knowledge of the dynamic situation of security inspection at each checkpoint, and automatically dispatch to the image judgment unit according to the inspection volume of the image judgment channel, and the image judgment unit performs image judgment on the items in the image judgment channel, and transmits the image judgment result to the management unit corresponding to the image judgment channel, and the image judgment result enables the management unit to perform early warning inspection on the items in the image judgment channel. At the same time, the data of all management units are summarized in the image judgment unit. Therefore, according to the remote centralized image judgment method of the present technical solution, timely and accurate feedback on the inspection volume, image judgment status, unpacking rate, and working hours can be obtained, so as to realize centralized management of all checkpoints, reasonable and real-time allocation of human resources, streamlining of positions, and reduction of labor costs.

[0015] 2) The remote centralized image judgment method for airport crossing security inspection according to 1), wherein:

[0016] In step S1, the package opening unit includes an X-ray security inspection machine, which has a photoelectric sensor for obtaining monitoring information of entering the security inspection work area. The photoelectric sensor transmits the monitoring information to the image judgment unit. After receiving the monitoring information from the photoelectric sensor, the image judgment unit performs image judgment in the image judgment channel between the package opening unit and the image judgment unit.

[0017] Through the above technical solution, the X-ray security inspection machine in the unpacking unit scans the items for contraband or dangerous goods. Before the X-ray security inspection machine works, the photoelectric sensor of the X-ray security inspection machine obtains the entry of the items into the security inspection work area. When the items enter the security inspection work area, the photoelectric sensor transmits the monitoring information of the items entering the security inspection work area to the image judgment unit. The image judgment unit will judge the image of the security checkpoint according to the monitoring information. In this way, the image judgment staff can continuously judge the images of each security checkpoint at each security checkpoint in real time, which can maintain the workload of the image judgment staff. At the same time, one image judgment staff can concentrate on judging the images of all security checks at all security checkpoints, thereby reducing labor costs.

[0018] 3) According to the remote centralized image judgment method applied to airport checkpoint security inspection as described in 2), image judgment is performed in the image judgment channel between the package opening unit and the image judgment unit, and the image judgment includes an X-ray image encoding module, a package opening image display module and a package opening recording module corresponding to each image judgment channel, the X-ray image encoding module is used to collect image information of items entering the security inspection work area, and send the image information to the package opening image display module, the package opening image display module is used to interpret the image information to obtain an image judgment result, and send the image judgment result to the package opening recording module for storage.

[0019] According to the above technical solution, each image judgment channel is provided with an X-ray image encoding module, a package opening image display module and a package opening recording module. Different image judgment channels are corresponded to by image judgment units. When a certain image judgment channel starts image judgment, the X-ray image encoding module collects image information of items entering the security inspection work area, and sends the image information to the package opening image display module. The package opening image display module interprets the image information to obtain an image judgment result, and sends the image judgment result to the package opening recording module for storage. Therefore, the image judgment unit performs centralized image judgment on each image judgment channel in real time. At the same time, compared with the existing technology, the image judgment staff can be gathered together and communicate in real time, so as to realize the smooth flow of information between crossings and centrally manage all crossings.

[0020] 4) According to 1), the remote centralized image judgment method for airport checkpoint security inspection, wherein the image judgment unit corresponds to different image judgment channels, and according to the inspection amount of the image judgment channel, it is automatically dispatched to the image judgment channel with the inspection amount matching, wherein the image judgment unit includes a remote image judgment scheduling server, and the image judgment scheduling server is used to receive the monitoring information of the X-ray security inspection machine and perform image judgment on the image judgment channel, including the following steps:

[0021] Step S21, the remote image judgment scheduling server synchronously obtains an image judgment channel in an "idle state" and an image judgment channel with a matching over-detection amount in the image judgment unit;

[0022] Step S22, the remote image judgment scheduling server starts the X-ray image encoding module, the package opening image display module and the package opening recording module in the image judgment channel with the matched inspection quantity in step S21 according to the state of the image judgment channel. Meanwhile, the X-ray image encoding module is arranged in the X-ray security inspection machine, and the package opening image display module and the package opening recording module are arranged in the image judgment unit, and the image judgment unit controls the image judgment time of the X-ray security inspection machine on the items;

[0023] Step S23: When the image judgment channel in step S22 is in the image judgment time, the other "idle" image judgment channels in step S21 are transformed into image judgment channels with matching inspection quantity, and the remote image judgment scheduling server will synchronously start the X-ray security inspection machine in the image judgment channel, and the image judgment time of the X-ray security inspection machine is in a scrolling manner with the image judgment time of the X-ray security inspection machine in step S22 to collect image information of items entering the security inspection work area;

[0024] Step S24: When more than two image judgment channels collect image information of items entering the security inspection work area in a scroll-like manner in step S23, the image judgment channels can be switched in real time through the remote image judgment scheduling server, and the image judgment unit performs image judgment on the image judgment channel that matches the inspection amount.

[0025] Through the above technical solution, all image judgment channels are centrally and uniformly managed through the remote image judgment scheduling server, wherein the image judgment channel has two states, the first state is the image judgment channel in "idle state", and the second state is the image judgment channel with a matching pass inspection amount. For the image judgment channel with a matching pass inspection amount, the image of the object is judged through the X-ray image encoding module, the package opening image display module and the package opening record module.

[0026] During the image judgment time, if an image judgment channel that was originally in the "idle state" is transformed into an image judgment channel with a matching inspection amount, the remote image judgment scheduling server will synchronously start the X-ray security inspection machine in the image judgment channel. The image judgment time of the X-ray security inspection machine and the image judgment time of other X-ray security inspection machines are used to collect image information of items entering the security inspection work area in a scroll-like manner, and a "scroll-type" centralized security inspection mode is adopted. This security inspection mode realizes the continuous push of image information of items to be inspected, and realizes switchable judgment of image information according to the inspection amount, which can avoid the technical problem of long waiting time for image information of new items to be inspected when the inspection density is high.

[0027] 5) According to the remote centralized image judgment method for airport checkpoint security inspection described in 4), collecting image information of objects entering the security inspection work area includes the following steps:

[0028] Step S231: a conveyor belt is provided in the X-ray security inspection machine to carry articles and transport them along a conveying direction, and an image of the articles on the conveyor belt is displayed in a "scroll-like" manner in the image judgment unit;

[0029] Step S232: In step S231, the image judging unit controls the forward, stop and backward operations of the conveyor belt, and the image information of the objects on the conveyor belt is accurately transmitted to the image judging unit and image processing is performed in the image judging unit to obtain image display information.

[0030] Through the above technical solution, the image judgment unit can realize remote control of the conveyor belt and the X-ray image encoding module in the X-ray security inspection machine. During the security inspection of items entering the security inspection work area, the items are placed on the conveyor belt carrying the items, and the image judgment unit remotely controls the forward, stop and backward movement of the conveyor belt. At the same time, the image information of the items collected by the X-ray security inspection machine through the X-ray image encoding module is accurately transmitted to the image judgment unit, and the image can be processed by the X-ray image encoding module to obtain image display information.

[0031] 6) The remote centralized image judgment method for airport crossing security inspection according to 5), wherein:

[0032] In step S232, during the continuous display of the scroll in the image judgment unit, the image display information is judged by the unpacking image display module in the image judgment unit to obtain an image judgment result, and the dangerous area in the image judgment result is calibrated to obtain dangerous area image information.

[0033] Through the above technical solution, the image judgment unit can scroll continuously and remotely control the image display information to be pulled back left and right, so as to adjust the image display information, which is convenient for the image judge to judge the image after adjusting the image display information through the unpacking image display module. During the judgment process, if dangerous area image information is found in the image display information, the image judge can calibrate the dangerous area in the image information of the object in the image judgment unit, and the operation is convenient and simple.

[0034] 7) The remote centralized image judgment method for airport crossing security inspection according to 6), wherein:

[0035] The image information of the dangerous area is transmitted to the security inspector by the information transmission unit arranged in the X-ray security inspection machine, and the security inspector performs unpacking operation and inspection on the articles on the conveyor belt.

[0036] Through the above technical solution, the information transmission unit can use voice, image and other information transmission methods to transmit the dangerous area image information to the security personnel, but is not limited to voice, image and other information transmission methods. After the security personnel obtain the dangerous area image information through the information transmission unit, they will open the packages and check the items on the conveyor belt.

[0037] 8) According to 1), the remote centralized image judgment method for airport checkpoint security, wherein the image judgment unit transmits the image judgment result to the management unit corresponding to the image judgment channel, comprises the following steps:

[0038] Step S31: The management unit is provided with an image retrieval module, an image playback module and an image statistics module. The image judgment unit transmits the image judgment result to the image statistics module. The image statistics module matches the package opening record module set in the image judgment channel. The image statistics module counts the image judgment result, and the package opening record module stores the image judgment result.

[0039] Step S32: Based on the fact that the package opening record module is connected with the image playback module and the image retrieval module in step S31, the image playback module is used to obtain the image determination result process in the package opening record module, and the image retrieval module is used to obtain the corresponding retrieval graphic determination result in the package opening record module.

[0040] Through the above technical solution, the image judges can centrally control all security checks at the checkpoints. The image judges perform scroll-type image judgment on the items, and the obtained image judgment results are transmitted to the image statistics module. The image statistics module counts the image judgment results of the image information of the items in a single image judgment channel, and the statistics are stored in the corresponding unpacking record module.

[0049] In the present invention, an X-ray security inspection machine is provided in the package opening unit, and a point-to-point wireless data transmission mode is realized between each X-ray security inspection machine and the image judgment unit. The wireless data transmission mode constructs an image judgment channel between the X-ray security inspection machine and the image judgment unit. In the present invention, all X-ray security inspection machines no longer need to be equipped with image judgment personnel. All image judgment personnel are concentrated in the area of ​​the image judgment unit, and the image judgment unit performs real-time judgment operation on the package opening image in each image judgment channel to obtain the image judgment result. Therefore, two scroll-type modes are used to realize a remote image judgment mode without delay. The first scroll-type mode is set in more than two image judgment channels to collect the image information of the items entering the security inspection working area in a scroll-type manner, so as to realize the continuous push of the image information of the items to be inspected, and realize the switchable judgment of the image information according to the inspection amount.

[0054] The following is further described in detail through specific implementation methods:

[0055] Now will be referred to in detail the embodiments disclosed in the present invention, although the present disclosure will be described in conjunction with the embodiments and / or examples, they are not intended to limit the present disclosure to these embodiments and / or examples. On the contrary, the present disclosure covers alternatives, modifications and equivalents.

[0056] For example, see Figure 1 As shown, the remote centralized image judgment method applied to airport crossing security inspection in this embodiment includes the following steps:

[0057] Step S1: Each road crossing security inspection work area is set with a package opening unit for obtaining a package opening image. The package opening units of all road crossing security inspection work areas are connected to a picture judgment unit. The picture judgment unit is connected with the package opening units of each road crossing security inspection work area to form a picture judgment channel. Each picture judgment channel corresponds to a matching management unit, and the data of all management units are summarized in the picture judgment unit.

[0058] Step S2, setting each road crossing security inspection work area as unmanned, with image judgment units corresponding to different image judgment channels, and automatically dispatching to the image judgment channel with matching inspection volume according to the inspection volume of the image judgment channel, while other image judgment channels are "idle";

[0059] Step S3: the image judging unit performs image judging on the image judging channel that matches the inspection quantity, and transmits the image judging result to the management unit corresponding to the image judging channel, and the management unit will start the early warning inspection of the unpacking unit.

[0060] A centralized image judgment structure is adopted, and the unpacking unit of each security inspection at the road crossing forms an independent image judgment channel with the image judgment unit respectively. All independent image judgment channels are centrally controlled by the image judgment unit to realize real-time and accurate knowledge of the dynamic situation of security inspection at each road crossing, and automatically dispatch to the image judgment unit according to the inspection volume of the image judgment channel. The image judgment unit performs image judgment on the items in the image judgment channel, and transmits the image judgment result to the management unit corresponding to the image judgment channel. The image judgment result enables the management unit to perform early warning inspection on the items in the image judgment channel. At the same time, the data of all management units are summarized in the image judgment unit. Therefore, the remote centralized image judgment method according to the technical solution can provide timely and accurate feedback on the inspection volume, image judgment status, unpacking rate, and working hours, realize centralized management of all road crossings, reasonably allocate human resources in real time, streamline positions, and reduce labor costs.

[0061] Among them, in step S1, the package opening unit includes an X-ray security inspection machine, and the X-ray security inspection machine has a photoelectric sensor for obtaining monitoring information entering the security inspection work area. The photoelectric sensor transmits the monitoring information to the image judgment unit. After the image judgment unit receives the monitoring information from the photoelectric sensor, it will perform image judgment in the image judgment channel between the package opening unit and the image judgment unit.

[0062] The X-ray security inspection machine in the unpacking unit scans the items for contraband or dangerous goods. Before the X-ray security inspection machine works, the photoelectric sensor of the X-ray security inspection machine obtains the items entering the security inspection work area. When the items enter the security inspection work area, the photoelectric sensor transmits the monitoring information of the items entering the security inspection work area to the image judgment unit. The image judgment unit will judge the image of the security checkpoint according to the monitoring information. This allows the image judgment staff to continuously judge the images of each security checkpoint at each security checkpoint in real time, which can maintain the workload of the image judgment staff. At the same time, one image judgment staff can concentrate on judging the images of all security checks at all security checkpoints, thereby reducing labor costs.

[0063] At the same time, in the above steps, image judgment is performed in the image judgment channel between the package opening unit and the image judgment unit. The image judgment includes an X-ray image encoding module, a package opening image display module and a package opening recording module corresponding to each image judgment channel. The X-ray image encoding module is used to collect image information of items entering the security inspection work area, and send the image information to the package opening image display module. The package opening image display module is used to interpret the image information to obtain an image judgment result, and send the image judgment result to the package opening recording module for storage.

[0064] Each image judgment channel is provided with an X-ray image encoding module, a package opening image display module and a package opening recording module. Different image judgment channels are corresponded to by image judgment units. When image judgment is started in a certain image judgment channel, the X-ray image encoding module collects image information of items entering the security inspection work area, and sends the image information to the package opening image display module. The package opening image display module interprets the image information to obtain an image judgment result, and sends the image judgment result to the package opening recording module for storage. Therefore, the image judgment unit performs centralized image judgment on each image judgment channel in real time. At the same time, compared with the existing technology, the image judgment staff can be gathered together and communicate in real time, so as to realize the smooth flow of information between the crossings and centrally manage all the crossings.

[0065] See also Figure 2 As shown, in this embodiment, the image judgment unit corresponds to different image judgment channels, and according to the inspection amount of the image judgment channel, it is automatically dispatched to the image judgment channel with the inspection amount matching. The image judgment unit includes a remote image judgment scheduling server, which is used to receive the monitoring information of the X-ray security inspection machine and perform image judgment on the image judgment channel, including the following steps:

[0066] Step S21, the remote image judgment scheduling server synchronously obtains an image judgment channel in an "idle state" and an image judgment channel with a matching over-detection amount in the image judgment unit;

[0067] Step S22, the remote image judgment scheduling server starts the X-ray image encoding module, the package opening image display module and the package opening recording module in the image judgment channel with the matched inspection quantity in step S21 according to the state of the image judgment channel. Meanwhile, the X-ray image encoding module is arranged in the X-ray security inspection machine, and the package opening image display module and the package opening recording module are arranged in the image judgment unit, and the image judgment unit controls the image judgment time of the X-ray security inspection machine on the items;

[0068] Step S23: When the image judgment channel in step S22 is in the image judgment time, the other "idle" image judgment channels in step S21 are transformed into image judgment channels with matching inspection quantity, and the remote image judgment scheduling server will synchronously start the X-ray security inspection machine in the image judgment channel, and the image judgment time of the X-ray security inspection machine is in a scrolling manner with the image judgment time of the X-ray security inspection machine in step S22 to collect image information of items entering the security inspection work area;

[0069] Step S24: When more than two image judgment channels collect image information of items entering the security inspection work area in a scroll-like manner in step S23, the image judgment channels can be switched in real time through the remote image judgment scheduling server, and the image judgment unit performs image judgment on the image judgment channel that matches the inspection amount.

[0070] All image judgment channels are centrally and uniformly managed through the remote image judgment scheduling server. The image judgment channel has two states. The first state is the "idle state" image judgment channel, and the second state is the image judgment channel with a matching pass quantity. For the image judgment channel with a matching pass quantity, the X-ray image encoding module, the package opening image display module and the package opening record module are used to perform object image judgment.

[0071] During the image judgment time, if an image judgment channel that was originally in the "idle state" is transformed into an image judgment channel with a matching inspection amount, the remote image judgment scheduling server will synchronously start the X-ray security inspection machine in the image judgment channel. The image judgment time of the X-ray security inspection machine and the image judgment time of other X-ray security inspection machines are used to collect image information of items entering the security inspection work area in a scroll-like manner, and a "scroll-type" centralized security inspection mode is adopted. This security inspection mode realizes the continuous push of image information of items to be inspected, and realizes switchable judgment of image information according to the inspection amount, which can avoid the technical problem of long waiting time for image information of new items to be inspected when the inspection density is high.

[0072] The process of collecting image information of items entering the security inspection work area includes the following steps:

[0073] Step S231: a conveyor belt is provided in the X-ray security inspection machine to carry articles and transport them along a conveying direction, and an image of the articles on the conveyor belt is displayed in a "scroll-like" manner in the image judgment unit;

[0074] Step S232: In step S231, the image judging unit controls the forward, stop and backward operations of the conveyor belt, and the image information of the objects on the conveyor belt is accurately transmitted to the image judging unit and image processing is performed in the image judging unit to obtain image display information.

[0075] The image judgment unit can realize remote control of the conveyor belt and X-ray image encoding module in the X-ray security inspection machine. During the security inspection of items entering the security inspection work area, the items are placed on the conveyor belt carrying the items, and the image judgment unit remotely controls the forward, stop and backward movement of the conveyor belt. At the same time, the image information of the items collected by the X-ray security inspection machine through the X-ray image encoding module is accurately transmitted to the image judgment unit, and the image can be processed by the X-ray image encoding module to obtain image display information.

[0076] In step S232, during the continuous display of the scroll in the image judgment unit, the image display information is judged by the unpacking image display module in the image judgment unit to obtain an image judgment result, and the dangerous area in the image judgment result is calibrated to obtain dangerous area image information.

[0077] The image judgment unit can scroll continuously and remotely control the image display information and can pull it back left and right to adjust the image display information, which is convenient for the image judge to judge the image after adjusting the image display information through the unpacking image display module. During the judgment process, if dangerous area image information is found in the image display information, the image judge can calibrate the dangerous area in the object image information in the image judgment unit, and the operation is convenient and simple.

[0078] At the same time, the image information of the dangerous area is transmitted to the security personnel by the information transmission unit installed in the X-ray security inspection machine, and the security personnel unpack and inspect the items on the conveyor belt.

[0079] The information transmission unit can transmit the dangerous area image information to the security personnel by means of voice, image and other information transmission methods, but is not limited to voice, image and other information transmission methods. After the security personnel obtain the dangerous area image information through the information transmission unit, they will open the packages and inspect the items on the conveyor belt.

[0080] During the scanning process, if the judge determines that the item is safe, no operation is required, no alarm is given on site, and the owner can take the item away. During the scanning process, the judge can stop the conveyor belt at any time and use various image processing functions for image analysis.

[0081] See also Figure 3 As shown, in this embodiment, the image judgment unit transmits the image judgment result to the management unit corresponding to the image judgment channel, including the following steps:

[0082] Step S31: The management unit is provided with an image retrieval module, an image playback module and an image statistics module. The image judgment unit transmits the image judgment result to the image statistics module. The image statistics module matches the package opening record module set in the image judgment channel. The image statistics module counts the image judgment result, and the package opening record module stores the image judgment result.

[0083] Step S32: Based on the fact that the package opening record module is connected with the image playback module and the image retrieval module in step S31, the image playback module is used to obtain the image determination result process in the package opening record module, and the image retrieval module is used to obtain the corresponding retrieval graphic determination result in the package opening record module.

[0084] Image judges can centrally control all security checks at checkpoints. They perform scroll-style image judgment on items, obtain image judgment results and pass them to the image statistics module. The image statistics module counts the image judgment results of the image information of items in a single image judgment channel, and stores them in the corresponding unpacking record module. When the image judgment results need to be replayed or retrieved, the image judgment results in the unpacking record module are extracted through the image playback module, and the image judgment results in the unpacking record module are extracted through the image retrieval module, which facilitates the realization of centralized digital control, can be traced, and can ensure the accuracy of the data.

[0085] In step S32, the image information of the dangerous area in the image determination result is sent to the X-ray security inspection machine, and the alarm is set on the X-ray security inspection machine, and the alarm is activated to prompt the security personnel to open the package for inspection of the items on the conveyor belt. The alarm implements early warning inspection of the image information of the dangerous area in the image determination result, and prompts the security personnel next to the X-ray security inspection machine to open the package for inspection of the items on the conveyor belt. At the same time, the X-ray security inspection machine is equipped with a video monitoring function, which allows the image judge to observe the unpacking situation in real time through the video monitoring function, so as to achieve the effect of remote real-time monitoring and judgment.

[0086] See also Figure 4 As shown, the remote centralized image recognition system applied to airport road crossing security inspection in this embodiment acts on the remote centralized image recognition method applied to airport road crossing security inspection, including:

[0087] A plurality of package opening units are configured to obtain package opening images in each security inspection work area at each road crossing;

[0088] The image judging unit is configured to be connected with all the package opening units, and there is an image judging channel between each package opening unit and the image judging unit, which can judge the package opening image in each roadside security inspection working area;

[0089] Several management units are configured to receive image determination results of the image determination unit on the package opening image in each image determination channel, and start early warning inspection on the package opening unit corresponding to the image determination channel according to the image determination results.

[0090] The unpacking unit is provided with an X-ray security inspection machine, and a point-to-point wireless data transmission mode is realized between each X-ray security inspection machine and the image judgment unit. The wireless data transmission mode constructs an image judgment channel between the X-ray security inspection machine and the image judgment unit. In the present invention, all X-ray security inspection machines no longer need to be equipped with image judgment personnel. All image judgment personnel are concentrated in the area of ​​the image judgment unit, and the image judgment unit performs real-time interpretation operation on the unpacking image in each image judgment channel to obtain the image judgment result. Therefore, two scroll-type modes are used to realize a remote image judgment mode without delay. The first scroll-type mode is set in more than two image judgment channels to collect the image information of the items entering the security inspection working area in a scroll-type manner, so as to realize the continuous push of the image information of the items to be inspected, and realize the switchable judgment of the image information according to the inspection amount. The second scroll-type mode is set in the image judgment unit to display the image of the item, so that the image judgment personnel can perform real-time operation in a "scroll-type" manner, thereby improving the convenience of the judgment personnel. Therefore, the entire investment cost is low, and it is automatically dispatched to the image judgment unit according to the inspection amount, effectively utilizing the human resources of the image judgment personnel, and improving the security inspection efficiency.

[0091] In addition, the beneficial effects of the present invention on security inspection efficiency, accuracy and staff satisfaction are as follows:

[0092] 1. Economic Benefit Analysis:

[0093] Before the implementation, 3 security inspectors were required at each of the 8 checkpoints every day. After the implementation, the average number of security inspectors was 2-4, with a median of 3 and a shift of 6. The staffing was reduced from 24 to 9, with a labor cost saving rate of about 62.5%. Based on an annual cost of 100,000 per employee, the annual cost saving is about 1.5 million, and the investment can be recovered within one year in theory.

[0094] 2. Improved safety margin:

[0095] Since the functional requirements of image review and quality control were fully considered during the system construction process, the security inspection quality is more effectively guaranteed and the security inspection margin is improved in terms of real-time response and quality control supervision intervention.

[0096] 3. Improvement of working environment:

[0097] Unlike the checkpoints located adjacent to the apron with limited conditions, the centralized image judging room located in the terminal building has a good working environment in all aspects, which is conducive to employees focusing their main energy on security inspection and protection.

[0098] 4. It is convenient for the management to grasp more comprehensive and accurate information of road crossing security inspection:

[0099] Due to the previous dispersion of security checks, security check management personnel at checkpoints were unable to obtain timely and accurate information on daily security check dynamics. After the implementation of the new system, timely and accurate feedback was provided on inspection traffic, image recognition, package opening rate, and working hours, providing strong data support for managers’ employee management and assessment work.

[0100] The above are only embodiments of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the technical solution of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
