[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field based on the present application belong to the scope of protection of the present application.

[0036] At present, there are some specific scenarios where it is necessary to perform distinguishing detection on mobile devices and other metal products carried by people passing through security gates. However, existing security gates cannot achieve this distinguishing detection in terms of functional implementation. Regardless of whether the people passing through carry the aforementioned mobile devices or other metal products, security alarms will be triggered. In order to achieve distinguishing detection of specific types of mobile devices and other metal products, an embodiment of the present application provides a security gate.

[0037] Among them, in the technical solution of the embodiment of the present application, the operations of obtaining, storing, using, processing, transmitting, providing and disclosing the user equipment information involved are all performed with the authorization of the user. Before describing the security door provided by the present application, the relevant technical concepts involved in the embodiment of the present application are first described.

[0038] 1. Electronic fence: A wireless data collection terminal that uses wireless mobile networks and electronic information technology to control specific areas or specific people. The electronic fence can be designed with a data collection function, which can collect the detection data of mobile devices that enter the preset range. The detection data includes the device characteristics of the mobile devices. Therefore, the mobile devices that enter the preset range can be classified by the device characteristics included in the detection data. Among them, the device characteristics collected by the electronic fence usually include: device model, and / or device brand, and mobile devices of different device models and mobile devices of different device brands can usually be classified into different types of mobile devices.

[0039] Take mobile phone electronic fences as an example. They are also called code detection devices. They are widely used in important areas such as highways, national roads, and road checkpoints around the city. They are used in conjunction with image acquisition equipment to conduct a comprehensive analysis of the information of vehicles entering and leaving the vehicle and the mobile phone information of people in the vehicle. The main technology is to obtain the IMSI (International Mobile Subscriber Identification Number) and IMEI (International Mobile Equipment Identity) of mobile terminals within the acquisition range by capturing mobile signals.

[0040] Among them, IMSI is a mark that distinguishes mobile users and is stored in the SIM (Subscriber Identity Module) card. It can be used to distinguish effective information of mobile users. It is an identification code used to distinguish different users in the cellular network and is not repeated in all cellular networks. IMEI is commonly referred to as the mobile phone serial number, mobile phone "serial number", etc., which is used to identify each independent mobile phone and other mobile communication devices in the mobile phone network. It is equivalent to the ID card of the mobile phone. Among them, IMEI usually consists of 15-17 digits, including the code to distinguish the brand and model of the mobile phone.

[0041] 2. Metal detection component: usually installed on the door panel of the security door, it has classification and identification capabilities, uses magnetic induction coil technology and metal classification algorithm technology, and can effectively distinguish mobile device signals from other metal product signals through hardware signal demodulation and software classification algorithm.

[0042] Generally, a security door used to distinguish mobile phones from other metal products is called a mobile phone security door. Taking a mobile phone security door as an example, it is used to identify mobile phones and other metal products, and can accurately detect whether a person passing through the door is carrying a mobile phone, and issue an alarm when a person passing through the door is detected to be carrying a mobile phone. Among them, a mobile phone security door can also be called a metal security door.

[0043] 3. Infrared light barrier: usually includes two infrared light barrier components, and the two infrared light barrier components are respectively set on both sides of the channel, and there is infrared signal transmission between the two. When people, equipment, etc. moving in the channel appear between the two infrared light barrier components, the infrared signal transmission between the two infrared light barriers will be blocked, thereby triggering the infrared light barrier. At this time, it can generate a trigger signal and send the above trigger signal to other devices to notify other devices that people, equipment, etc. have appeared.

[0044] Among them, infrared light barriers can exist in various forms according to the working principle. For example, a beam-type infrared light barrier includes two infrared light barrier components, one for transmitting infrared signals and the other for receiving infrared signals. When a person, equipment, etc. appears between the two infrared light barriers, the infrared light barrier component for receiving infrared signals is triggered because it cannot receive infrared signals, so as to output a trigger signal. Another example is a reflective infrared light barrier, which includes two infrared light barrier components, one for transmitting infrared signals and the other for reflecting infrared signals transmitted to itself. The infrared light barrier component for transmitting infrared signals is also used to receive infrared signals reflected by the reflector on the other side, thereby realizing the same-side transmission and reception of infrared signals. In this way, the infrared light barrier component for transmitting infrared signals is triggered because it cannot receive infrared signals reflected by the reflector on the other side, so as to output a trigger signal.

[0045] 4. Gate channel: a channel blocking device that allows only one person to pass at a time. The gate can be opened and closed by swiping a card, scanning a face, scanning a code, or linking with an external signal.

[0046] The security door provided in the embodiment of the present application can be applied to various places where it is necessary to distinguish and detect specific types of mobile devices and other metal products, such as research institutes, schools, factories, etc. In this regard, the embodiment of the present application does not limit the specific application places of the above security door.

[0047] The security door provided in the embodiment of the present application includes: a security door body, and a controller, an electronic fence and a metal detection component installed on the security door body;

[0048] The electronic fence is used to collect the code detection data of mobile devices within the preset range of the security gate and transmit the collected frame code data to the controller;

[0049] A controller, used to transmit the received frame code data to a shared database; wherein the shared database supports common access by multiple security gates, and stores the frame code data according to the corresponding relationship between the security gates and the frame code data;

[0050] The metal detection component is used to detect the electromagnetic signal caused by the object passing through the security door and send the electromagnetic signal to the controller;

[0051] The controller is further used to determine whether there is a target mobile device closest to the security gate by accessing the frame code data in the shared database;

[0052] If it is determined that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is detection code data belonging to the whitelist, and if it is determined based on the electromagnetic signal detected by the metal detection component that the detection object carries the target mobile device, it is determined that the detection object has passed security inspection.

[0053] Below, in conjunction with the accompanying drawings, the security door provided in the embodiment of the present application is described in detail.

[0054] Figure 1 This is a schematic diagram of the structure of a security door provided in an embodiment of the present application. Figure 1 As shown, the security door includes: a security door body 100 , and a controller 101 , an electronic fence 102 , and a metal detection component 103 installed on the security door body 100 .

[0055] Among them, Figure 1 As shown, the security door body 100 includes two door panels and a chassis, and the passage area between the two door panels can be called the security door passage of the security door, or simply the security door passage. Usually, when passing through the security door passage, the area near the security door for entering the security door passage can be called the entrance passage along the passage direction of the security door. That is to say, when passing through the security door, the passerby first enters the entrance passage, then enters the security door passage from the entrance passage, continues to pass through the security door passage, and then leaves the security door passage to enter other areas outside the security door passage. Among them, in the passage direction of the above-mentioned security door, the above-mentioned entrance passage and the above-mentioned other areas are respectively located on both sides of the security door.

[0056] The electronic fence 102 is used to collect the detection data of the mobile devices within the preset range of the security gate (the preset range can be reasonably determined according to the collection requirements and the detection range of the electronic fence antenna), and transmit the collected detection data to the controller 101.

[0057] The electronic fence 102 has an angle-adjustable detection antenna. When installing the electronic fence 102, the detection antenna can be first made perpendicular to the ground, and then the angle of the detection antenna can be adjusted according to the detection needs, so that the detection range of the detection antenna can cover the entire area or part of the area of ​​the above-mentioned entrance channel. The detection range of the above-mentioned detection antenna can be a fan-shaped area. The farther the mobile device is from the detection antenna, the weaker the signal strength of the detection data of the mobile device detected by the detection antenna of the electronic fence 102. The above-mentioned mobile device can be a portable device such as a mobile phone, a smart watch, and a smart bracelet.

[0058] Optionally, the electronic fence 102 may be disposed in the chassis of the security door body 100, and the detection range of the detection antenna of the electronic fence 102 covers the preset range of the entrance passage of the security door. The preset range may be the entire area or a part of the entrance passage of the security door, and, as Figure 1 As shown, the chassis of the security door body 100 can usually be located at the top of the security door.

[0059] Since the detection range of the detection antenna is the collection range of the electronic fence 102, the electronic fence 102 can collect the detection data of the mobile device entering the detection range. Therefore, the detection range of the detection antenna is the collection area of ​​the electronic fence 102 in this application. Exemplarily, the collection area may include the preset range of the entrance passage, and in some cases, the collection area may also include the security gate passage. The collection area can be used as the preset range of the security gate, and the electronic fence 102 can collect the detection data of the mobile device within the preset range of the security gate.

[0060] The electronic fence 102 can exchange data with the controller 101 through a wired network, a wireless network, a data bus, etc., so that the electronic fence 102 can transmit the collected detection code data to the controller 101. Optionally, the electronic fence 102 can only exchange data with the controller 101 of the security gate where it is located.

[0061] The above-mentioned detection data may include device features for classifying mobile devices into types. For example, the above-mentioned detection data may include the device model and / or device brand of the mobile device as the device features.

[0062] Optionally, when the electronic fence 102 does not collect the detection data, it may send a notification to the controller 101 indicating that the detection data has not been collected.

[0063] Optionally, the electronic fence 102 can collect the code detection data of the mobile devices within the preset range of the security gate in real time, and transmit the collected code detection data to the controller 101 in real time.

[0064] The controller 101 is used to transmit the received frame code data to a shared database; wherein the shared database supports common access by multiple security gates, and stores the frame code data according to the corresponding relationship between the security gates and the frame code data.

[0065] Exemplarily, the controller 101 may be installed at any position on the security door. Figure 1 As shown, the controller 101 is installed inside a chassis at the top of the security door body 100 .

[0066] In many cases, due to the large security inspection scene, or when the number of inspection objects that need to be inspected is large, multiple security inspection gates can be set in the same security inspection scene, so that the multiple security inspection gates can share the same database, and the database can be called a shared database, and supports multiple security inspection gates to access together, that is, the shared database supports multiple security inspection gates installed controllers to access together. Therefore, in order to enable the controller installed at each security inspection gate to read the detection data of the mobile device collected by the electronic fence installed at other security inspection gates in the shared database, the above-mentioned controller 101 can transmit the received detection data to the shared database when receiving the data transmitted by the electronic fence 102 installed at the security inspection gate where it is located. In this way, the shared database can store the detection data according to the corresponding relationship between the security inspection gate and the detection data, that is, the corresponding relationship between the security inspection gate and the detection data can be stored in the shared database, and the security inspection gate corresponding to each stored detection data is the security inspection gate where the electronic fence that collected the detection data is located. By setting up a shared database, it is possible to avoid the situation where the controller in the security gate misidentifies the target mobile device closest to it due to mutual interference between the frame code data signals collected by the electronic fence when multiple people (greater than or equal to two people) pass through the security gate in front and behind due to the close distance. This is because when a mobile device is closest to the security gate, the frame code data of the mobile device collected by the electronic fence on the security gate has the strongest signal value, and then by judging and comparing the strength of the frame code data signals belonging to the same mobile device, it is possible to confirm the security gate closest to the mobile device.

[0067] Among them, since the detection range of the detection antenna of the electronic fence 102 has a certain width, and the detection data with a smaller signal strength collected by the electronic fence 102 contributes less to the equipment security inspection of the security gate, therefore, in order to reduce the information interaction between the electronic fence 102 and the controller 101 to save resource consumption, for example, to save the power consumption of the security gate, etc., the electronic fence 102 can transmit the detection data to the controller 101 only when the detection data with a larger signal strength is collected.

[0068] Optionally, in a specific implementation, the electronic fence 102 is specifically used to collect the detection data of the mobile device within the preset range of the security gate in real time, and transmit the frame code data whose data value exceeds the data threshold in the collected frame code data to the controller. Correspondingly, in this specific implementation, the controller 101 is specifically used to transmit the received frame code data to the shared database in real time.

[0069] In this specific implementation, the electronic fence 102 collects the detection data of the mobile device within the preset range of the security gate in real time. When the data value of the collected detection data exceeds the data threshold, the detection data with the data value exceeding the data threshold is transmitted to the controller 101, and the controller 101 can transmit the received frame code data to the shared database in real time. The so-called data value exceeding the data threshold means that the signal strength of the detection data exceeds the strength threshold.

[0070] In addition, optionally, when the controller 101 transmits detection data to the shared database, the controller 101 may carry one or more of the identification information of the security gate where the controller 101 is located, the identification information of the controller 101, and the identification information of the electronic fence 102 installed at the security gate where the controller 101 is located in the above-mentioned detection data. Thus, when the controller 101 subsequently accesses the shared database, it can determine whether the detection data is sent by itself to the shared database through the identification information carried in the detection data.

[0071] In some cases, for the same security gate, the identification information of the security gate, the identification information of the controller 101 of the security gate, and the identification information of the electronic fence 102 of the security gate may be the same. Then, when the controller 101 of the security gate sends the detection data to the shared database, it only needs to carry one identification information on the detection data.

[0072] The metal detection component 103 is used to detect the electromagnetic signal generated when the detection object passes through the security gate, and send the electromagnetic signal to the controller 101.

[0073] Among them, the metal detection component 103 can distinguish the mobile device signal from other metal product signals based on the magnetic induction coil. Therefore, when the detection object passes through the security gate, the metal detection component 103 can detect the electromagnetic signal caused by the metal product carried by the detection object in the above process. Among them, the detection object is a person passing through the security gate. Depending on the different metal products carried by the detection object, the electromagnetic signal detected by the metal detection component 103 is also different. The type of metal product carried by the detection object can be determined based on the above electromagnetic signal to determine whether the detection object carries a mobile device.

[0074] Among them, since the metal detection component 103 detects the electromagnetic signal caused by the detection object passing through the security gate, the detection area of ​​the metal detection component 103 can usually include the security gate passage, and in some cases, the above detection area can also include the area in the above entrance area. That is to say, in some cases, the detection area of ​​the metal detection component 103 and the detection range of the detection antenna of the electronic fence 102 may overlap.

[0075] Similar to the above-mentioned electronic fence 102 , the metal detection component 103 can also exchange data with the controller 101 through a wired network, a wireless network, a data bus, etc., so that the metal detection component 103 can send the detected electromagnetic signal to the controller 101 .

[0076] The metal detection component 103 can detect in real time the electromagnetic signal generated when the detection object passes through the security gate, and send the detected electromagnetic signal to the controller 101 in real time.

[0077] The controller 101 is also used to determine whether there is a target mobile device that is closest to the security gate by accessing the detection data in the shared database; if it is determined that there is a target mobile device that is closest to the security gate, and the detection data of the target mobile device is data belonging to the white list, and if it is determined based on the electromagnetic signal detected by the metal detection component 103 that the detection object carries the target mobile device, it is determined that the detection object has passed the security check.

[0078] In some specific scenarios, it is necessary to prevent people carrying specific types of mobile devices from passing through the security gate. For example, during security checks in certain factory areas, workers are not allowed to enter with certain brands of mobile phones. Usually, the types of devices can be classified according to the device features of the mobile devices, and the above-mentioned detection code data can include the device features used to classify the types of mobile devices.

[0079] Based on this, a whitelist can be pre-set, and the whitelist includes device features of one or more specific types of mobile devices that are allowed to pass through the security gate, so that mobile devices with device features in the whitelist can be regarded as safe devices, which have the authority to pass through the security gate, and mobile devices that do not have device features belonging to the whitelist can be regarded as dangerous devices, which do not have the authority to pass through the security gate. Among them, when the device features included in the detection data collected by the electronic fence 102 are device features belonging to the above whitelist, the detection data can be determined as detection data belonging to the whitelist.

[0080] As mentioned above, the farther the mobile device is from the detection antenna of the electronic fence 102, the weaker the signal strength of the detection data of the mobile device detected by the detection antenna of the electronic fence 102. Since the electronic fence 102 is installed on the security gate, the mobile device closest to the security gate has a stronger signal strength of the detection data of the mobile device collected by the electronic fence 102. Based on this, the controller 101 can access the detection data in the shared database and determine whether there is a target mobile device closest to the security gate according to the signal strength of the detection data stored in the shared database.

[0081] When accessing the code detection data in the shared database, the controller 101 may determine whether there is a target mobile device that is closest to the security gate in a variety of ways.

[0082] For example, when accessing the detection data in the shared database, the controller 101 can determine the detection data with the strongest signal strength among the detection data corresponding to the security gate where it is located, and then determine whether the detection data is the detection data with the strongest signal among all the detection data stored in the shared data and belonging to the same mobile device as the detection data. If so, the controller 101 can determine that there is a target mobile device that is closest to the security gate, and the target mobile device is the mobile device with the detection data with the strongest signal strength determined above.

[0083] For another example, when accessing the detection data in the shared database, the controller 101 can determine the detection data with the strongest signal strength among the detection data stored in the shared database, and then determine whether the security gate corresponding to the detection data with the strongest signal strength is the security gate where the controller 101 is located. If so, the controller 101 can determine that there is a target mobile device that is closest to the security gate, and the target mobile device is the mobile device with the detection data with the strongest signal strength determined above.

[0084] Furthermore, since the mobile device with the detection code data belonging to the white list has the authority to pass through the security gate, and the metal detection component 103 can detect the electromagnetic signal caused by the metal products carried by the detection object when the detection object passes through the security gate, and the electromagnetic signals caused by different types of metal products are different, therefore, after determining that there is a target mobile device closest to the security gate and obtaining the detection code data of the target mobile device, the controller 101 can further determine whether the detection code data of the target mobile device is the detection code data belonging to the white list, and determine whether the electromagnetic signal detected by the received metal detection component is an electromagnetic signal caused by a metal product of the type to which the above-mentioned target mobile device belongs, so as to determine whether the above-mentioned detection object carries the above-mentioned target mobile device when passing through the security gate.

[0085] In this way, when the controller 101 determines that there is a target mobile device that is closest to the security gate and the frame code data of the target mobile device is detection code data belonging to the whitelist, and based on the electromagnetic signal detected by the metal detection component, it is determined that the detection object carries the target mobile device, it can be explained that the detection object carries a mobile device with permission to pass through the security gate when passing through the security gate, and the detection object can pass through the security gate. Therefore, the controller 101 can determine that the detection object has passed the security check.

[0086] Among them, in the actual application scenario, when the detection object carries a mobile device through the security gate, the timing of the mobile device carried by the detection object triggering the above-mentioned electronic fence 102 to collect the detection data and triggering the above-mentioned metal detection component 103 to detect the electromagnetic signal is relatively close, or even the same, and for the detection object carrying the mobile device, the above-mentioned detection data and the electromagnetic signal should appear in pairs, so that the above-mentioned controller 101 can receive the above-mentioned detection data and the electromagnetic signal in a short time range, and even can receive the above-mentioned detection data and the electromagnetic signal at the same time. Therefore, when the time interval between the receiving moments is short, the detection data and the electromagnetic signal received by the controller 101 can be regarded as the detection data and the electromagnetic signal for the same mobile device. Based on this, optionally, the above-mentioned controller 101 can trigger the security inspection process of the security gate when receiving the detection data, that is, access the detection data in the shared database to determine whether there is a target mobile device closest to the security gate, and determine whether the detection object carries the above-mentioned target mobile device based on the most recently received electromagnetic signal, so as to finally determine whether the detection object has passed the security inspection.

[0087] Based on this, optionally, in a specific implementation, the controller 101 is also used to associate the electromagnetic signal detected by the metal detection component 103 with the frame code data of the target mobile device when the detection object carries the target mobile device through the security gate.

[0088] In this specific implementation, when the controller 101 determines that there is a target mobile device that is closest to the security gate, the frame code data of the target mobile device is blacklisted detection data, and the detection object is carrying the target mobile device, the electromagnetic signal detected by the metal detection component 103 when the detection object carries the target mobile device through the security gate can be associated with the detection data of the above-mentioned target mobile device.

[0089] For example, when it is determined that there is a target mobile device that is closest to the security gate, the frame code data of the target mobile device is detection data belonging to the blacklist, and the detected object carries the target mobile device, the controller 101 can associate the detection data transmitted by the electronic fence 102 and the electromagnetic signal sent by the metal detection component 103 to facilitate subsequent information backtracking, etc.

[0090] As mentioned above, in an embodiment of the present application, for example, when the target mobile device is a mobile phone, in addition to the function of the metal security door to classify and identify mobile phones and other metal products, a code data detection function of the mobile phone is added, and the above-mentioned classification and identification function and detection function are combined to accurately distinguish the types of mobile phones, so as to realize the special mobile phone management and control function in confidential places.

[0091] Continuing to take the mobile phone security gate as an example, the existing mobile phone security gates all use metal detection technology to classify and identify metal objects such as mobile phones, contraband, and daily items, but cannot achieve more accurate and detailed classification of different models of mobile phones; and the existing mobile phone electronic fence (detection code) and other equipment technologies are currently mainly used to assist smart homes, front-end cameras and other products, and are generally used to detect mobile phone signals within a large range, and cannot accurately identify and locate people. In the embodiment of this application, the above two technologies can be combined, the metal detection data of the security gate and the electronic fence data can be integrated, and in conjunction with the gate channel, targeted control of mobile phones carried by people entering and leaving a specific place can be achieved, effectively solving the mobile phone control needs of special places.

[0092] Based on the actions performed by the controller 101, the electronic fence 102 and the metal detection component 103 and the interactions between them, it can be determined that during the security inspection process, the signaling interactions between the controller 101, the electronic fence 102 and the metal detection component 103 are as follows: Figure 2 As shown, it is a signaling interaction diagram between the controller 101, the electronic fence 102 and the metal detection component 103 installed in the above-mentioned security gate, wherein the signaling interaction between the above-mentioned controller 101, the electronic fence 102 and the metal detection component 103 may include the following steps S201-S207.

[0093] S201: The electronic fence 102 collects code detection data of mobile devices within a preset range of the security gate.

[0094] S202 : The electronic fence 102 transmits the collected detection data to the controller 101 .

[0095] S203: The controller 101 transmits the received detection data to the shared database.

[0096] S204: The metal detection component 103 detects the electromagnetic signal generated when the detection object passes through the security gate.

[0097] S205 : the metal detection component 103 sends an electromagnetic signal to the controller 101 .

[0098] S206: The controller 101 determines whether there is a target mobile device that is closest to the security gate by accessing the detection code data in the shared database.

[0099] S207: If it is determined that there is a target mobile device that is closest to the security gate, and the detection data of the target mobile device is data belonging to the whitelist, and if it is determined based on the electromagnetic signal detected by the metal detection component that the detection object carries the target mobile device, it is determined that the detection object has passed the security check.

[0100] As can be seen from the above, by applying the solution provided by the embodiment of the present application, a controller, an electronic fence and a metal detection component can be installed on the security door body. The metal detection component can realize the distinguishing detection of mobile devices and other metal products, and the electronic fence can realize the distinguishing detection of different types of mobile devices. Based on this, the controller can integrate the code detection data collected by the electronic fence and the electromagnetic signal detected by the metal detection component to realize the double security check of whether there is a mobile device and whether the mobile device is a specific type of device, that is, to realize the distinguishing detection of a specific type of mobile device and other metal products, thereby realizing more detailed equipment security inspection, meeting the security inspection requirements of specific places for further refinement of specific types of mobile devices, and then realizing targeted control of mobile devices such as mobile phones carried by people entering and leaving a specific place, effectively solving the mobile device control needs of special places. In addition, through the configuration of a shared database, the misidentification of mobile devices by the security door is reduced.

[0101] Since the detection range of the detection antenna of the electronic fence 102 has a certain width, when the distance between the front and rear detection objects that want to pass through the same security inspection gate is relatively close, the electronic fence 102 can basically collect the detection code data of the mobile devices carried by the front and rear detection objects at the same time, that is, collect multiple different detection code data at the same time, and there is mutual interference between these multiple different detection code data, which affects the accuracy of the security inspection results of the detection objects determined by the controller 101. In other words, in a single channel, if the distance between the front and rear detection objects is relatively close, there is mutual signal interference between the multiple detection code data.

[0102] For example, Figure 3As shown, the gate passage area is the passage area of ​​the gate passage associated with the security gate, the video surveillance area is the collection area of ​​the image collection device installed on the security gate, the metal detection channel is the detection area of ​​the metal detection component 103, the effective code detection area is the detection range of the detection antenna of the electronic fence 102, and the arrow direction is the passage direction of the security gate. When the detection object 301 and the detection object 302 are close to each other, they may enter the effective code detection area at the same time. In this way, the electronic fence 102 can collect the code detection data of the mobile devices carried by the detection object 301 and the detection object 302 at the same time, so that there is signal interference between the two collected code detection data.

[0103] Based on this, optionally, in a specific implementation, the security door further includes: a first position detection sensor arranged at the entrance side of the security door body and a second position detection sensor arranged at the exit side of the security door body;

[0104] Accordingly, in this specific implementation:

[0105] The first position detection sensor is used to send a first trigger signal to the controller after being triggered by a detected object according to the passing direction of the security door.

[0106] The second position detection sensor is used to send a second trigger signal to the controller after being triggered by the detected object according to the passing direction of the security door.

[0107] The controller 101 is specifically configured to determine the frame code data whose acquisition time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal as valid data, and transmit the received valid data to the shared database.

[0108] In this specific implementation, a first position detection sensor may be provided at the entrance side of the security door body, and a second position detection sensor may be provided at the exit side of the security door body. In the process of the detection object passing through the security door, the detection object passes through the security door in the direction of travel of the security door, therefore, the detection object may trigger the first position detection sensor when entering the security door passage, and trigger the second position detection sensor when leaving the security door passage. Therefore, the first position sensor may send a first trigger signal to the controller 101 according to the direction of travel of the security door after being triggered by the detection object, and correspondingly, the second position sensor may send a second trigger signal to the controller 101 according to the direction of travel of the security door after being triggered by the detection object.

[0109] Among them, for the same detection object, when it passes through the security gate, the first position detection sensor and the second position detection sensor can be triggered sequentially and continuously, so that the first position detection sensor sends a first trigger signal to the controller 101, and the second position detection sensor sends a second trigger signal to the controller 101. Thus, the controller 101 can receive the first trigger signal and the second trigger signal in sequence, and the second trigger signal is the second trigger signal received for the first time after the controller 101 receives the first trigger signal. That is, for the same detection object, when it passes through the security gate, the controller 101 can receive a first trigger signal and a second trigger signal in sequence and continuously. Based on this, for the controller 101, when it receives a first trigger signal, it can determine that a detection object enters the security gate channel, and when the controller 101 receives the second trigger signal for the first time after the first trigger signal, it can determine that the first trigger signal and the second trigger signal are triggered by the same detection object, and the time period between the trigger time of the trigger signal and the second trigger signal is the time period when the same detection object passes through the security gate. However, in general, multiple detection objects are not allowed to exist in the security gate channel. Therefore, between the first trigger signal and the second trigger signal, the controller 101 usually does not receive another first trigger signal.

[0110] In this way, when the controller 101 receives the above-mentioned first trigger signal and the second trigger signal in sequence and continuously, it can determine that the above-mentioned first trigger signal and the second trigger signal are triggered by the same detection object, and then, the detection data whose acquisition time is between the trigger time of the above-mentioned first trigger signal and the trigger time of the second trigger signal received in sequence and continuously is the detection data of the mobile device carried by the same detection object. Therefore, the controller 101 can determine the frame code data whose acquisition time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal as valid data, and transmit the received valid data to the shared database. That is, the controller 101 can determine the detection data whose acquisition time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal received in sequence and continuously as valid data, and transmit the received valid data to the shared database.

[0111] That is to say, after receiving the detection data transmitted by the electronic fence 102, the controller 101 will screen the detection data according to the collection time of the detection data. When the collection time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal, the detection data will be transmitted to the shared database as valid detection data, and when the collection time is outside the trigger time of the first trigger signal and the trigger time of the second trigger signal, the detection data will be ignored as invalid detection data, for example, deleted, etc. Based on this, it is possible to reduce the storage of more invalid detection data in the shared database to reduce the storage space occupied, and reduce the resource consumption when the controller 101 sends the detection data to the shared database. For example, the power consumption of the security gate is saved.

[0112] Below, the specific implementation method is explained by taking an infrared light barrier as a position detection sensor as an example.

[0113] For example, Figure 4 As shown, the security door further includes: an entrance infrared light barrier 104 (first position detection sensor) installed on the entrance side of the security door body 100 and an exit infrared light barrier (second position detection sensor) installed on the exit side of the security door body 100. The entrance infrared light barrier 104 includes two infrared light barrier components, which are respectively installed on two door panels. Similarly, the exit infrared light barrier also includes two infrared light barrier components, which are also respectively installed on two door panels.

[0114] Figure 4 If it is a front view of the security door in the direction of passage of the security door, the entrance infrared light barrier 104 installed on the entrance side of the security door body 100 can be displayed, while the exit infrared light barrier cannot be displayed because it is blocked by the door panel. Figure 3 If it is a top view of the security door, it can simultaneously display the entrance infrared light barrier installed on the entrance side of the security door body 100 and the exit infrared light barrier installed on the exit side of the security door body 100, such as Figure 3 The entrance infrared and exit infrared shown are the entrance infrared light barrier and exit infrared light barrier installed at the security door respectively.

[0115] For infrared light barriers, when people, equipment, etc. appear between two infrared light barrier components, the infrared light barriers will be triggered due to blocking the transmission of infrared signals between the two infrared light barriers, so that the infrared light barriers will send trigger signals to other devices to notify other devices that people, equipment, etc. appear.

[0116] Based on this, when the entrance infrared light barrier 104 is triggered, it can be said that a detection object has entered the security gate passage, and after the entrance infrared light barrier 104 is triggered, when the exit infrared light barrier is triggered for the first time, it can be said that the detection object that entered the security gate passage has left the security gate passage. The triggering process of the entrance infrared light barrier 104 being triggered, and the exit infrared light barrier being triggered for the first time after the entrance infrared light barrier 104 is triggered, can be called the entrance infrared light barrier 104 and the exit infrared light barrier being triggered sequentially and continuously.

[0117] That is to say, within the time range when the entrance infrared light barrier 104 and the exit infrared light barrier are triggered sequentially and continuously, there is a situation where the same detection object passes through the security gate channel, that is, within the time range when the entrance infrared light barrier 104 and the exit infrared light barrier are triggered sequentially and continuously, the same detection object experiences the process of entering and leaving the security gate channel.

[0118] Among them, in the above process, the distance between the detection object and the electronic fence 102 has undergone a change from far to near and then from near to far. Since the signal strength of the detection data collected by the electronic fence 102 is inversely proportional to the distance, that is, the farther the detection object is from the electronic fence 102, the smaller the signal strength of the detection data of the mobile device carried by the detection object collected by the electronic fence 102 is, and the closer the detection object is to the electronic fence 102, the greater the signal strength of the detection data of the mobile device carried by the detection object collected by the electronic fence 102 is. Therefore, in the above process, there is a moment when the signal strength of the detection data collected by the electronic fence 102 is the largest, and this moment can be called the signal maximum moment.

[0119] by Figure 3Taking the detection object 301 and the detection object 302 shown in the figure as an example, for the convenience of description, the mobile device carried by the detection object 301 is referred to as device 1, and the mobile device carried by the detection object 302 is referred to as device 2. Among them, the detection object 301 first enters the code detection area, and the electronic fence 102 continues to collect the code detection data of device 1. When the detection object 301 is closer and closer to the electronic fence 102, the signal strength of the code detection data of device 1 collected by the electronic fence 102 is getting stronger and stronger. After that, the detection object 302 enters the code detection area, and the electronic fence 102 continues to collect the code detection data of device 2. When the detection object 302 is closer and closer to the electronic fence 102, the signal strength of the code detection data of device 2 collected by the electronic fence 102 is getting stronger and stronger. Then, the detection object 301 first reaches the nearest position to the electronic fence 102. At this time, the signal strength of the code detection data of device 1 collected by the electronic fence 102 is the largest. After that, the signal strength of the code detection data of device 1 collected by the electronic fence 102 is getting smaller and smaller until it cannot be collected. The detection object 302 will reach the closest position to the electronic fence 102 after the detection object 301. At this time, the signal strength of the detection data of device 2 collected by the electronic fence 102 is the largest. After that, the signal strength of the detection data of device 1 collected by the electronic fence 102 becomes smaller and smaller until it cannot be collected.

[0120] Obviously, the moment when the electronic fence 102 collects the detection data of the device 1 with the largest signal strength is earlier than the moment when the electronic fence 102 collects the detection data of the device 2 with the largest signal strength. For the sake of clarity, the moment when the electronic fence 102 collects the detection data of the device 1 with the largest signal strength is referred to as the first maximum moment, and the moment when the electronic fence 102 collects the detection data of the device 2 with the largest signal strength is referred to as the second maximum moment, that is, the first maximum moment is earlier than the second maximum moment.

[0121] Moreover, in the above process, the detection object 301 first enters the security gate passage, at which time the entrance infrared light barrier 104 is triggered for the first time. During the movement of the detection object 301 in the security gate passage, the detection object 302 then enters the security gate passage, at which time the entrance infrared light barrier 104 is triggered for the second time. During the movement of the detection object 302 in the security gate passage, the detection object 301 first leaves the security gate passage, at which time the exit infrared light barrier is triggered for the first time; thereafter, the detection object 302 then leaves the security gate passage, at which time the exit infrared light barrier is triggered for the second time. During the movement of the detection object 301 in the security gate passage, the metal detection component 103 can detect the electromagnetic signal caused by the above device 1, and similarly, during the movement of the detection object 302 in the security gate passage, the metal detection component 103 can also detect the electromagnetic signal caused by the above device 2.

[0122] Obviously, the time range between the moment when the entrance infrared light barrier 104 is first triggered and the moment when the exit infrared light barrier is first triggered is earlier than the time range between the moment when the entrance infrared light barrier 104 is second triggered and the moment when the exit infrared light barrier is second triggered. For the sake of clarity, the time range between the moment when the entrance infrared light barrier 104 is first triggered and the moment when the exit infrared light barrier is first triggered is referred to as the first time range, and the time range between the moment when the entrance infrared light barrier 104 is second triggered and the moment when the exit infrared light barrier is second triggered is referred to as the second time range, and the first time range is earlier than the second time range.

[0123] As mentioned above, the above-mentioned first maximum moment is within the above-mentioned first time range, and the above-mentioned second maximum moment is within the above-mentioned second time range. For the above-mentioned first time range, the detection data with the largest signal strength collected by the electronic fence 102 within the first time range is the detection data of the device 1 carried by the above-mentioned detection object 301, and the above-mentioned first time range is the time range for the above-mentioned detection object 301 to pass through the above-mentioned security gate channel.

[0124] Based on this, within the time range when the entrance infrared light barrier 104 and the exit infrared light barrier are triggered successively and continuously, the electronic device to which the detection code data with the largest signal strength collected by the electronic fence 102 belongs is the electronic device carried by the detection object passing through the security gate channel within the above time range. Moreover, within the above time range, the electromagnetic signal detected by the metal detection component 103 is the electromagnetic signal caused by the mobile device carried by the detection object passing through the security gate channel within the above time range. Among them, passing through the security gate channel within the above time range can mean: entering the security gate channel at the starting time of the above time range, and leaving the security gate channel at the end time of the above time range.

[0125] In summary, the entrance infrared light barrier 104 can report a first trigger signal to the controller 101 when triggered by a detected object, and the exit infrared light barrier can report a second trigger signal to the controller 101 when triggered by a detected object.

[0126] In this way, the controller 101 can determine the first trigger signal and the second trigger signal received sequentially and continuously, wherein the receiving time of the above-mentioned first trigger signal is earlier than the receiving time of the above-mentioned second trigger signal, and the above-mentioned second trigger signal is the first second trigger signal received after receiving the above-mentioned first trigger signal. Afterwards, the controller 101 can determine the triggering time of the entrance infrared light barrier 104 represented by the above-mentioned first trigger signal as the starting time, and determine the triggering time of the exit infrared light barrier represented by the above-mentioned second trigger signal as the ending time. Then, the controller 101 can determine the detection data with the collection time between the above-mentioned starting time and the ending time as valid data in the detection data transmitted by the electronic fence 102, and transmit the determined valid data to the shared database. Obviously, the above-mentioned valid data is the detection data of the mobile device carried by the detection object passing through the security gate between the above-mentioned starting time and the ending time.

[0127] As mentioned above, the detection data collected between the trigger time of the first trigger signal and the trigger time of the second trigger signal sequentially and continuously received by the controller 101 is the detection data of the mobile device carried by the same detection object. For the metal detection component 103, the electromagnetic signal detected between the trigger time of the first trigger signal and the trigger time of the second trigger signal sequentially and continuously received by the controller 101 is the electromagnetic signal caused by the mobile object carried by the same detection object. Therefore, the electromagnetic signal detected between the trigger time of the first trigger signal and the trigger time of the second trigger signal sequentially and continuously received by the controller 101 can be directly used to determine whether the detection object carries the target mobile device.

[0128] Based on this, optionally, in a specific implementation, the controller 101 is specifically used to determine an electromagnetic signal whose detection time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal as a valid electromagnetic signal, and determine whether the detection object carries a target mobile device based on the valid electromagnetic signal.

[0129] Exemplarily, the metal detection component in the security gate can continuously collect electromagnetic signals, and then determine the effective electromagnetic signals during the time when the detection object passes through the security gate according to the trigger time of the position detection sensors (such as infrared light barriers) at the entrance and exit.

[0130] Exemplarily, the entrance infrared light barrier 104 and the exit infrared light barrier can be respectively connected to the metal detection component 103 for communication. In this way, after the entrance infrared light barrier 104 is triggered, it can send the first trigger signal to the metal detection component 103 while sending the first trigger signal to the controller 101; similarly, after the exit infrared light barrier is triggered, it can send the second trigger signal to the metal detection component 103 while sending the second trigger signal to the controller 101. In this way, the metal detection component 103 can start the electromagnetic signal detection function when receiving the first trigger signal to start the electromagnetic signal detection of the metal products carried by the inspection object, and after starting the electromagnetic signal detection, stop the electromagnetic signal detection when receiving the first second trigger signal. Then the electromagnetic signals sent by the metal detection component 103 to the controller 101 are all electromagnetic signals whose detection time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal, and the controller 101 can determine the received electromagnetic signal as a valid electromagnetic signal, and determine whether the inspection object carries the target mobile device based on the received electromagnetic signal.

[0131] As mentioned above, Figure 3 For example, the detection object 301 and the detection object 302 shown in the figure are used as examples. The detection object 301 first enters the security inspection gate passage. At this time, the entrance infrared light barrier 104 is triggered for the first time. The entrance infrared light barrier 104 sends the first first trigger signal to the metal detection component 103, and the metal detection component 103 starts electromagnetic signal detection. Obviously, the electromagnetic signal detection initiated by the metal detection component 103 is for the metal products carried by the detection object 301. After that, the detection object 301 moves in the security inspection gate passage, and the metal detection component 103 continues to perform electromagnetic signal detection. Then, the detection object 301 leaves the security inspection gate passage after passing through the entire security inspection gate passage. At this time, the exit infrared light barrier is triggered for the first time, and the exit infrared light barrier sends the first second trigger signal to the metal detection component 103. The first second trigger signal is the first second trigger signal received by the metal detection component 103 after the metal detection component 103 starts the above electromagnetic signal detection. Then, the metal detection component 103 stops electromagnetic signal detection.

[0132] Since, in general, multiple persons are not allowed to exist in the security inspection channel, after the detection object 301 leaves the security inspection channel, the detection object 302 enters the security inspection channel. At this time, the entrance infrared light barrier 104 is triggered for the second time, and the entrance infrared light barrier 104 sends a second first trigger signal to the metal detection component 103, and the metal detection component 103 starts electromagnetic signal detection again. Obviously, the electromagnetic signal detection started by the metal detection component 103 this time is for the metal products carried by the detection object 302. After that, the detection object 302 moves in the security inspection channel, and the metal detection component 103 continues to perform electromagnetic signal detection; then, the detection object 302 leaves the security inspection channel after passing through the entire security inspection channel. At this time, the exit infrared light barrier is triggered for the second time, and the exit infrared light barrier sends a second second trigger signal to the metal detection component 103, and the second trigger signal is the first second trigger signal received after the metal detection component 103 starts electromagnetic signal detection again, and the metal detection component 103 stops electromagnetic signal detection.

[0133] Based on this, as mentioned above, within the time range when the entrance infrared light barrier 104 and the exit infrared light barrier are triggered sequentially and continuously, the mobile device to which the detection data collected by the electronic fence 102 belongs is the mobile device carried by the detection object passing through the security gate within the above time range. Similarly, within the above time range, the electromagnetic signal detected by the metal detection component 103 is caused by the mobile device carried by the detection object passing through the security gate within the above time range.

[0134] In this way, the controller 101 can realize a strong association between the effective electromagnetic signal and the effective detection code data generated during the same door-passing, and use it as the identification basis for the mobile device detected during the door-passing, and determine the security inspection result of the target mobile device carried by the detection object during the door-passing. Based on this, the embodiment of the present application proposes a signal processing method for accurately associating the electromagnetic signal and detection code data of the mobile device, reducing the interference of the previous and next door-passing signals, and improving the accuracy of mobile device type detection. Among them, the so-called door-passing refers to: the process from the same person entering the security door channel to leaving the security door channel, and the so-called door-passing period can be understood as the time range in which the entrance infrared light barrier 104 and the exit infrared light barrier are triggered sequentially and continuously.

[0135] In many cases, due to the large security inspection scene or the large number of inspection objects to be inspected, multiple security inspection gates can be set in the same security inspection scene. When the distance between the security inspection gates is close, the electronic fence 102 installed on one security inspection gate can simultaneously collect the detection data of the mobile devices carried by the inspection objects passing through multiple security inspection gates, that is, collect multiple different detection data at the same time, and there is mutual interference between these multiple different detection data, which affects the accuracy of the security inspection results of the inspection objects determined by the controller 101. That is to say, in multiple channels, when people in adjacent channels pass by at the same time, there is mutual signal interference between the detection data.

[0136] For example, Figure 5 As shown, the gate channel area is the passage area of ​​the gate channel associated with the security gate, and the video surveillance area is the acquisition area of ​​the image acquisition device installed at the security gate. Security gate channel 1 and security gate channel 2 are arranged in parallel, and the detection object 501 is about to pass through security gate channel 1, and the detection object 502 is about to pass through security gate channel 2. Among them, the signal coverage range of the mobile device carried by the detection object 502 is area 503, and there is an overlapping area between the area 503 and the detection area of ​​the security gate channel 2, so the electronic fence 102 of the security gate channel 2 can collect the detection data of the mobile device carried by the detection object 501.

[0137] Then, when the detection object 501 moves to the bottom of the electronic fence A of the security gate channel 1, and the detection object 502 moves to the bottom of the electronic fence B of the security gate channel 2, as shown in FIG. Figure 6As shown, it is assumed that the radius of the detection range of the detection antennas of the electronic fence A and the electronic fence B is greater than the height of the electronic fence A and the electronic fence B, that is, greater than D1 (where D1=D2, both are the heights of the electronic fence A and the electronic fence B); and, it is assumed that the mobile device carried by the detection object 501 entering the security gate channel 1 is located at point E, and at the same time, the mobile device carried by the detection object 502 entering the security gate channel 2 is located at point F. For the sake of simplicity, the mobile device carried by the detection object 501 is referred to as device a, and the mobile device carried by the detection object 502 is referred to as device b. According to the relevant geometric principle, the distance between device a and the electronic fence A is greater than the distance between device b and the electronic fence A. At this time, the signal strength of the detection data of device a collected by the electronic fence A is less than the signal strength of the detection data of device b collected by the electronic fence A. When determining the detection data of the mobile device carried by the detection object 501 passing through the security gate channel 1, the detection data of the mobile device b carried by the detection object 502 not passing through the security gate channel 1 collected by the electronic fence A may cause misjudgment of the detection data. But in fact, because device b passed through the security gate channel 2, the frame code data signal strength of device b collected by the electronic fence B is greater than the detection data signal strength of device b collected by the electronic fence A.

[0138] Based on this, optionally, in a specific implementation method, the controller 101 is specifically used to: access the frame code data in the shared database; if the frame code data with the largest data value among the frame code data collected during the target time period and belonging to the same mobile device is uploaded by the controller of the current security gate, then the mobile device is determined as the target mobile device that is closest to the current security gate.

[0139] The target time period is the time period during which the detection object passes through the current security gate.

[0140] Optionally, as mentioned above, for each security door, when the security door further includes: a first position detection sensor arranged at the entrance side of the security door body and a second position detection sensor arranged at the exit side of the security door body, the first position detection sensor of the security door can report a first trigger signal to the controller 101 of the security door when triggered by the detected object according to the passage direction of the security door, and the second position detection sensor of the security door can report a second trigger signal to the controller 101 of the security door when triggered by the detected object according to the passage direction of the security door. In this way, the controller 101 of the security door can use the time period between the trigger time of the first trigger signal and the trigger time of the second trigger signal received sequentially and continuously as the target time period.

[0141] Since there are multiple security gates in the same scene, the electronic fence 102 installed on one security gate can simultaneously collect the detection data of mobile devices carried by the detection objects passing through multiple security gates. Therefore, in the shared database, there may be detection data of the same mobile device collected by the electronic fences 102 of different security gates.

[0142] The above-mentioned detection data may include a device identification, and the device indicates the mobile device to which the detection data belongs, that is, there is a one-to-one correspondence between the mobile device and the device identification, and the detection data including the same device identification belongs to the detection data of the same mobile device. Since the signal strength of the detection data collected by the electronic fence 102 is inversely proportional to the distance, therefore, for the same mobile device, when the electronic fences 102 of multiple security gates all collect the detection data of the mobile device, among the above-mentioned multiple detection data, the detection data with the largest signal strength is collected by the electronic fence 102 of the security gate through which the mobile device passes.

[0143] For example, the electronic fences of security gate 1, security gate 2, and security gate 3 all collect detection data of mobile device 4, wherein a person carrying mobile device 4 passes through security gate 2. Then, among the multiple detection data of mobile device 4 collected by the electronic fences of security gate 1, security gate 2, and security gate 3, the detection data with the largest signal strength is collected by the electronic fence of security gate 2.

[0144] Based on this, for each security gate, the controller 101 of the security gate can access the shared database to determine whether the frame code data with the largest data value (i.e., the frame code data with the largest signal strength) among the frame code data whose collection time is within the target time period and belongs to the same mobile device is uploaded by the controller 101 of the security gate. For example, the controller 101 of the security gate can determine in the shared database multiple detection code data whose collection time is within the target time period and belongs to the same mobile device; then, among the multiple detection code data, search for the detection code data with the largest data value; then, determine whether the detection code data with the largest data value is sent to the shared database by itself. If so, the mobile device to which the detection code data with the largest data value belongs can be determined as the target mobile device closest to the security gate.

[0145] As mentioned above, the controller 101 determines that the detection object has passed the security check when it is determined that there is a target mobile device closest to the security gate and the frame code data of the target mobile device is detection code data belonging to the whitelist, and when it is determined that the detection object carries the target mobile device based on the electromagnetic signal detected by the metal detection component. In actual application scenarios, there are many situations, and the controller 101 can determine different security inspection results for different situations.

[0146] For example, there is a target mobile device that is closest to the security gate, the frame code data of the target mobile device is blacklisted detection data, and the detection object carries the target mobile device; for another example, based on the electromagnetic signal detected by the metal detection component 103, it is determined that the detection object carries the target mobile device, but the detection data transmitted by the electronic fence 102 is not received; for another example, there is no target mobile device that is closest to the security gate, and based on the electromagnetic signal detected by the metal detection component, it is determined that the detection object does not carry the target mobile device, etc.

[0147] Based on this, optionally, in a specific implementation, the controller 101 can also be used to perform at least one of the following steps 1-4.

[0148] Step 1: If it is determined that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is data in the blacklist, a security warning signal is issued.

[0149] As mentioned above, a whitelist can be pre-set to record specific types of mobile devices that have the authority to pass through the security gate. Correspondingly, a blacklist can also be pre-set, and the blacklist includes device features of one or more specified types of mobile devices that are not allowed to pass through the security gate, so that mobile devices with device features in the blacklist can be regarded as dangerous devices, which do not have the authority to pass through the security gate. Among them, when the device features included in the detection data collected by the electronic fence 102 are device features belonging to the above blacklist, the detection data can be determined as detection data belonging to the blacklist.

[0150] Among them, when both a whitelist and a blacklist exist, the device features in the whitelist and the blacklist are completely different.

[0151] In this way, if the controller 101 determines that there is a target mobile device that is closest to the security gate, and the detection data of the above target mobile device is the detection data in the blacklist, then regardless of whether the detection object carries the target mobile device, it can be considered that there are dangerous devices trying to pass through the security gate near the security gate, and the detection object has the possibility of carrying dangerous devices. Therefore, in order to improve safety, it can be considered that the detection object has failed the security check, and thus, a security check warning signal is issued to prompt the staff near the security gate to be vigilant and pay attention to the surrounding environment.

[0152] In some cases, when the controller 101 issues the security warning signal, it can indicate the presence of dangerous equipment to provide direction for the subsequent security inspection work of the staff, and when receiving the security warning signal, the staff can prevent the detected object from passing through the security gate.

[0153] Step 2: If it is determined that the detected object carries the target mobile device based on the electromagnetic signal detected by the metal detection component 103, but the frame code data transmitted by the electronic fence is not received, a security inspection warning signal is issued.

[0154] In some cases, when the detection object passes through the security gate, the metal detection component 103 detects an electromagnetic signal, so the controller 101 can determine that the detection object carries the target mobile device based on the electromagnetic signal detected by the metal detection component 103. However, when the detection object carries the above-mentioned target mobile device into the preset range of the security gate, the electronic fence 102 does not collect the detection data of the above-mentioned target mobile device, so it is impossible to determine whether the above-mentioned target mobile device has the authority to pass through the security gate (it is impossible to determine whether the detection data of the above-mentioned target mobile device is the detection data belonging to the whitelist). Therefore, in these cases, it can be considered that there are mobile devices of unknown types near the security gate. At this time, the above-mentioned unknown type of device can be regarded as a suspicious device. Considering that the security risk brought by the suspicious device may be higher, therefore, in order to improve security, it can be considered that the detection object does not pass the security check, so a security check warning signal is issued to prompt the staff near the security gate to be vigilant and pay attention to the surrounding environment.

[0155] In some cases, when the controller 101 issues the security warning signal, it can indicate the presence of suspicious equipment to provide direction for the subsequent security inspection work of the staff, and when receiving the security warning signal, the staff can prevent the detected object from passing through the security gate.

[0156] Usually, when the electronic fence 102 collects code detection data, what is collected is the code detection data of the mobile device in the power-on state. For example, the electronic fence 102 can collect the IMSI and IMEI of the mobile phone in the power-on state as the code detection data. Regardless of whether the mobile device is in the power-on state or the power-off state, the metal detection component 103 can detect the electromagnetic signal caused by the mobile device. Based on this, when the detection object carrying the mobile device in the power-off state wants to pass through the security gate, the metal detection component 103 detects the electromagnetic signal, and the electronic fence 102 cannot collect the code detection data, so it is impossible to know whether the mobile device carried by the detection object has the authority to pass through the security gate. Therefore, it can be considered that the mobile device carried by the detection object is a suspicious device, and the detection object will not pass the security check.

[0157] In addition, there are some situations where there is a person with a target mobile device near the security gate and outside the detection range of the detection antenna of the electronic fence 102. At this time, the above-mentioned metal detection component 103 can detect the electromagnetic signal, so the controller 101 may misjudge that the detection object is carrying the target mobile device, and the electronic fence 102 cannot collect the detection code data. It can be considered that the detection object is carrying a suspicious device, and the detection object fails the security check.

[0158] Among them, in the above steps 1 and 2, the controller 101 can send out a security warning signal in a variety of ways. For example, a voice announcer can be installed on the security door, and the controller 101 can control the voice announcer to send out a voice warning message as a security warning signal; for another example, a signal light can be installed on the security door, and the controller 101 can control the signal light to flash as a security warning signal; for another example, a buzzer can be installed on the security door, and the controller 101 can control the buzzer to emit a sound to output a security warning signal. This embodiment of the application does not make specific limitations on this.

[0159] Step 3: If it is determined that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is detection code data in the whitelist, and if it is determined based on the electromagnetic signal detected by the metal detection component 103 that the detection object does not carry the target mobile device, it is determined that the detection object has passed security inspection.

[0160] If the controller 101 determines that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is detection code data in the white list, it can be said that the above-mentioned target mobile device has the authority to pass through the security gate. At this time, even if it is determined based on the electromagnetic signal detected by the metal detection component 103 that the detection object does not carry the target mobile device, it can also be determined that the detection object has passed the security check.

[0161] Step 4: If it is determined that there is no target mobile device closest to the security gate, and it is determined based on the electromagnetic signal detected by the metal detection component that the detection object does not carry the target mobile device, it is determined that the detection object has passed the security check.

[0162] If the controller 101 determines that there is no target mobile device closest to the security gate, and determines based on the electromagnetic signal detected by the metal detection component 103 that the detection object does not carry the target mobile device, it can be explained that the detection object does not carry any dangerous equipment that does not have the authority to pass through the security gate. At this time, it can be determined that the detection object has passed the security check.

[0163] Optionally, in the above steps 3 and 4, when the controller 101 determines that the detection object has passed the security check, it can output a security check pass signal to prompt the detection object and the staff near the security check gate that the detection object can pass the security check gate. For example, a voice announcer can be installed on the security check gate, and the controller 101 can control the voice announcer to send out voice pass information as a security check pass signal; for another example, a signal light can be installed on the security check gate, and the controller 101 can control the signal light to emit green light as a security check pass signal. This embodiment of the application does not make specific limitations on this.

[0164] However, in actual application scenarios, there may be situations other than those corresponding to the above steps 1-4.

[0165] Optionally, in some cases, the controller 101 may determine that there is a target mobile device closest to the security gate, but has not received the electromagnetic signal sent by the metal detection component 103. For example, a person carrying the target mobile device stays at a position far away from the security gate and within the detection range of the detection antenna of the electronic fence 102. At this time, the electronic fence 102 can collect the code detection data of the target mobile device carried by the person. However, since the person just stays there and does not enter the security gate passage, the metal detection component 103 cannot detect the electromagnetic signal caused by the target mobile device carried by the person.

[0166] In the above case, if the detection data collected by the electronic fence 102 is detection data belonging to the white list, it can be considered that there are no suspicious devices and dangerous devices at this time, and the controller 101 can determine that there is no abnormal security inspection situation at present.

[0167] Correspondingly, in the above situation, if the detection data collected by the electronic fence 102 is not white-listed detection data, or is black-listed detection data, the controller 101 can determine that there is a dangerous device near the security gate that does not have the authority to pass through the security gate, then the controller 101 can determine that there is an abnormal security inspection situation at present, and thus, a security inspection warning signal can be issued to prompt the security inspection personnel near the security inspection gate to improve the safety protection effect of the security inspection gate.

[0168] Optionally, in some cases, there is no detection object, and the controller 101 does not receive the detection data transmitted by the electronic fence 102, nor does it receive the electromagnetic signal sent by the metal detection component 103. At this time, the controller 101 may not trigger the subsequent security inspection process of the security inspection gate, or the controller 101 may also determine that there is no abnormal security inspection situation at present.

[0169] When the detection object fails the security check, in order to improve the security protection effect of the security gate, it is usually necessary to further understand the details of the target mobile device carried by the detection object that does not have the authority to pass through the security gate, so as to focus on the detection object and the target mobile device it carries.

[0170] Based on this, optionally, in a specific implementation, the security door also includes a display device.

[0171] Accordingly, in this specific implementation, the display device is used to: display the information of the target mobile device when the controller 101 determines that there is a target mobile device that is closest to the security gate and the frame code data of the target mobile device is data on the blacklist, and when it is determined based on the electromagnetic signal detected by the metal detection component 103 that the detection object carries the target mobile device.

[0172] In this specific implementation, when the controller 101 determines that there is a target mobile device that is closest to the security gate, and the detection code data of the target mobile device is the detection code data belonging to the blacklist, and the detection object is determined to carry the target mobile device based on the electronic signal detected by the metal detection component 103, it can be explained that the detection object that currently wants to pass through the security gate carries a dangerous device, and the detection object and the dangerous device it carries cannot pass through the security gate. In order to enable the staff to understand the information of the above-mentioned target mobile device that is a dangerous device, the display device can display the information of the above-mentioned target mobile device, including but not limited to, for example, device identification, device shape, device type, etc. Among them, the display device can be connected to the above-mentioned controller 101 for communication, and the controller can send the information of the above-mentioned target mobile device to the display device, so that the display device can display the received information of the above-mentioned target mobile device. The information of the above-mentioned target mobile device can include the detection code data of the target mobile device.

[0173] In addition, optionally, a background terminal can be pre-set, and the background terminal is communicatively connected to the controller 101. Then, when the controller 101 determines that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is data on the blacklist, and based on the electromagnetic signal detected by the metal detection component 103, it is determined that the detection object carries the target mobile device, the controller 101 can send the detection result of the detection object failing the security check and the detection code data of the above-mentioned target mobile device to the above-mentioned background terminal, so that the background staff can understand the specific security inspection situation at the front-end security gate, thereby making targeted adjustments to the work at the front-end security gate and other processing.

[0174] Usually, the security gate can often be linked with the gate channel, and the gate channel is set behind the security gate, or the gate channel is directly installed on the security gate body, so that the detection object can enter the gate channel after passing the security check at the security gate, and obtain the pass authority of the gate channel by swiping a card, scanning a face, scanning a code, etc., so as to pass the gate channel and finally enter the place you want to enter.

[0175] Based on this, optionally, in a specific implementation, the security door is associated with a gate channel.

[0176] Correspondingly, in this specific implementation, the controller 101 is also used to send a prompt message to the gate channel that the detected object has passed the security check, so that the gate channel is in a passable state.

[0177] In this specific implementation, the controller 101 is connected to the controller of the gate channel through a wired network, a wireless network, a data bus, etc. After obtaining the security inspection result for the detection object, the controller 101 can send the above security inspection result to the controller of the associated gate channel, so that the controller of the gate channel can control the gate opening and closing of the gate channel based on the above security inspection result. In this way, the security door can be used with the gate channel to achieve control over the in and out personnel.

[0178] Among them, when the controller 101 determines that the detection object has passed the security check, it can be explained that in the current situation, the detection object hopes to pass through the security gate and the gate passage, and the detection object has the authority to pass through the security gate. At this time, the controller 101 can send an indication message that the detection object has passed the security check to the gate passage, so that the gate passage is in a passable state. For example, the controller 101 sends a prompt message that the detection object has passed the security check to the controller of the gate passage, and the controller of the gate passage controls the door wing of the gate passage to open, so that the gate passage is in a passable state.

[0179] Optionally, in some cases, after receiving the indication message that the detection object has passed the security check, the gate channel can further determine whether the detection object has the authority to pass through the gate channel by swiping a card, swiping a face, scanning a code, etc. That is, after the detection object passes through the above-mentioned security gate, the gate channel can determine that the detection object has the authority to pass through the gate channel by swiping a card, swiping a face, scanning a code, etc., so that it is in a passable state. Correspondingly, when the detection object, after passing through the above-mentioned security gate, determines that the detection object does not have the authority to pass through the gate channel by swiping a card, swiping a face, scanning a code, etc., the gate channel can be in an inaccessible state. At this time, even if the detection object passes through the security gate, it will not be able to pass through the gate channel, so that the detection object still cannot enter the place it wants to enter.

[0180] As mentioned above, when the above-mentioned security gate is associated with a gate channel, in some cases, even if the controller 101 determines that the inspection object has passed the security check, the gate channel still needs to determine whether the inspection object has the authority to pass the gate channel.

[0181] Based on this, optionally, in a specific implementation, when the controller 101 associates the electromagnetic signal detected by the metal detection component 103 with the frame code data of the target mobile device when the detection object carries the target mobile device through the security gate, the controller 101 is further used to:

[0182] After obtaining the identity information of the detected object, according to the association between the identity information of the detected object and the frame code data of the target mobile device, the pass information is sent to the gate channel associated with the security gate to make the gate channel passable.

[0183] In this specific implementation, the identity information of the detection object may include a variety of information, such as name, job position, authority conditions, etc., so that the detection object can be determined under what circumstances the detection object has the authority to pass through the gate channel according to the identity information of the detection object. In particular, in order to allow the detection object to smoothly pass through the gate channel associated with the security gate when passing the security check, an association relationship between the detection object's identity information and the detection code data of the target mobile device can be established in advance to indicate that when the detection object carries the target mobile device, it can have the authority to pass through the security gate and the gate channel.

[0184] Based on this, after obtaining the identity information of the detection object, if the identity information of the detection object is associated with the detection code data of the target mobile device, the controller 101 can determine that the detection object has the authority to pass through the gate channel, so that the controller 101 can send pass information to the gate channel associated with the security door to make the gate channel in a passable state.

[0185] In addition, optionally, in the case where the above-mentioned security gate is associated with a gate passage, when the controller 101 sends a security warning signal, it means that the controller 101 determines that the detection object has not passed the security inspection, and the detection object does not have the authority to pass through the security gate and the gate passage. In this way, the controller 101 can send an indication message to the gate passage that the detection object has not passed the security inspection, so that the controller of the gate passage controls the gate passage to close, so that the gate passage is in an impassable state. For example, the controller 101 sends a prompt message to the controller of the gate passage that the detection object has not passed the security inspection, and the controller of the gate passage controls the door wing of the gate passage to close, so that the gate passage is in an impassable state.

[0186] Optionally, as mentioned above, when there is currently no detection object that wants to pass through the security gate, the controller of the gate channel can directly control the gate channel to close, so that the gate channel is in an inaccessible state.

[0187] In addition, optionally, in some cases, in order to reduce the interaction pressure between the controller 101 and the controller of the gate channel, the controller 101 may send an indication message of the detection object failing the security check to the controller of the gate channel only when the detection object fails the security check. At this time, the controller of the gate channel may directly control the gate channel to be closed, so that the gate channel is in an impassable state, and until the closing release condition is met, the gate channel is controlled to restore the passable state. For example, when the closing time of the gate channel reaches a specified time, when the closing release signal sent by the controller 101 is received, when the pressing operation of the closing release button set by the gate channel is detected, etc. Among them, during the time period from the above-mentioned receipt of the indication message of the detection object failing the security check to the satisfaction of the closing release condition, the gate channel is in an abnormal working state, that is, no person can pass through the gate channel by performing actions such as swiping a card, swiping a face, scanning a code, etc. Correspondingly, except for the time period from the receipt of the indication message that the inspection object failed the security check to the satisfaction of the closure release conditions, the gate channel is in normal working condition, that is, the controller of the gate channel can determine whether a person has the authority to pass the gate channel through actions such as swiping a card, swiping a face, or scanning a code, and whether the person has the authority to control the opening and closing of the gate channel.

[0188] Optionally, the security door body 100 may also be equipped with an image acquisition device such as a camera to capture the video of the detection object passing through the security door channel and the gate channel as the detection object passing through the door video.

[0189] For example, Figure 7 As shown, a camera is installed on the security door body 100, and a gate swing leaf is installed on the gate column, and the gate opening and closing of the gate channel is controlled by controlling the gate swing leaf. When the gate swing leaf is open, the gate channel is in a passable state, and when the gate swing leaf is closed, the gate channel is in a blocked state. Since the gate channel is usually set behind the security door, Figure 7 If it is a rear view of the security door in the passing direction of the security door, the exit infrared light barrier can be displayed, while the entrance infrared light barrier 104 cannot be displayed because it is installed on the opposite side of the door panel where the exit infrared light barrier is located and is blocked by the door panel.

[0190] In this way, for the detection object with the permission to carry mobile devices, the permission information of the detection object to pass through the gate channel can be associated with the detection code data of the target mobile device carried by the detection object collected by the electronic fence 102 of the security gate through scanning code, face recognition or card swiping, and after the association is successful, the gate of the gate channel is linked to open to be in a passable state. At the same time, when the detection object passes through the security gate and the gate channel, the video of the detection object passing through the door obtained by the camera, the electromagnetic signal detected by the metal detection component 103, the detection code data of the target mobile device collected by the electronic fence 102, etc. can be uploaded to the background terminal for recording, so as to facilitate the subsequent information reverse query of the above detection object, ensure that there is no tailing, etc., and ensure strict control of mobile devices in the venue.

[0191] Corresponding to the above-mentioned security inspection door, an embodiment of the present application also provides an equipment security inspection method. Figure 8 This is a flow chart of a device security inspection method provided in an embodiment of the present application, and the device security inspection method is applied to the controller of any security inspection door provided in the above-mentioned embodiment of the present application. Figure 8 As shown, the device security inspection method may include the following steps S801-S804.

[0192] S801: Receive the detection data transmitted by the electronic fence, and transmit the detection data to a shared database.

[0193] S802: Receive the electromagnetic signal sent by the metal detection component.

[0194] S803: Determine whether there is a target mobile device that is closest to the security gate by accessing the code detection data in the shared database.

[0195] S804: If it is determined that there is a target mobile device that is closest to the security gate, and the frame code data of the target mobile device is detection code data belonging to the whitelist, and if it is determined based on the electromagnetic signal detected by the metal detection component that the detection object carries the target mobile device, it is determined that the detection object has passed the security check.

[0196] As can be seen from the above, by applying the solution provided in the embodiment of the present application, a controller, an electronic fence and a metal detection assembly can be installed on the security door body. The metal detection assembly can realize the distinguishing detection of mobile devices and other metal products, and the electronic fence can realize the distinguishing detection of different types of mobile devices. Based on this, the controller can integrate the code detection data collected by the electronic fence and the electromagnetic signal detected by the metal detection assembly to realize double security checks on whether there are mobile devices and whether the existing mobile devices are of a specific type of device, that is, to realize the distinguishing detection of a specific type of mobile device and other metal products, thereby realizing more detailed equipment security inspection, meeting the security inspection requirements of specific places for further refinement of the distinction of specific types of mobile devices, and then realizing targeted control of mobile devices such as mobile phones carried by people entering and leaving a specific place, effectively solving the mobile device control needs of special places.

[0197] Optionally, in a specific implementation, the above step S803, by accessing the detection code data in the shared database, determines whether there is a target mobile device that is closest to the security gate, including:

[0198] Access the frame code data in the shared database; if the acquisition time is within the target time period and among the frame code data belonging to the same mobile device, the frame code data with the largest data value is uploaded by the controller of the current security gate, then the mobile device is determined as the target mobile device closest to the current security gate; wherein the target time period is the time period when the detection object passes through the current security gate.

[0199] Optionally, in a specific implementation, the above step S801, receiving the detection data transmitted by the electronic fence, and transmitting the detection data to the shared database, includes:

[0200] Receive in real time the frame code data of the data value collected in real time by the electronic fence and exceeding the data threshold, and transmit the received frame code data to the shared database in real time.

[0201] Optionally, in a specific implementation, the security door further comprises: a first position detection sensor disposed at an entrance side of the security door body and a second position detection sensor disposed at an exit side of the security door body; the method further comprises:

[0202] receiving a first trigger signal sent by the first position detection sensor according to the passage direction of the security door after being triggered by the detection object, and receiving a second trigger signal sent by the second position detection sensor according to the passage direction of the security door after being triggered by the detection object;

[0203] In the above step S801, the detection data is transmitted to the shared database, including:

[0204] The frame code data whose acquisition time is between the trigger time of the first trigger signal and the trigger time of the second trigger signal is determined as valid data, and the received valid data is transmitted to the shared database.

[0205] Optionally, in a specific implementation, the method further includes:

[0206] An electromagnetic signal whose detection time is between the triggering time of the first triggering signal and the triggering time of the second triggering signal is determined as a valid electromagnetic signal, and based on the valid electromagnetic signal, it is determined whether the detection object carries the target mobile device.

[0207] Optionally, in a specific implementation, the security door is associated with a gate channel, and the method further includes:

[0208] An indication message indicating that the detection object has passed security inspection is sent to the gate channel, so that the gate channel is in a passable state.

[0209] Optionally, in a specific implementation, the method further includes at least one of the following steps:

[0210] If it is determined that there is a target mobile device that is closest to the security inspection gate, and the frame code data of the target mobile device is detection code data in the blacklist, a security inspection warning signal is issued;

[0211] If it is determined based on the electromagnetic signal detected by the metal detection component that the detected object carries the target mobile device, but the frame code data transmitted by the electronic fence is not received, a security inspection warning signal is issued;

[0212] If it is determined that there is a target mobile device that is closest to the security inspection gate, and the frame code data of the target mobile device is detection code data in the whitelist, and if it is determined based on the electromagnetic signal detected by the metal detection component that the detection object does not carry the target mobile device, then it is determined that the detection object has passed the security inspection;

[0213] If it is determined that there is no target mobile device closest to the security gate, and it is determined based on the electromagnetic signal detected by the metal detection component that the detection object does not carry the target mobile device, it is determined that the detection object has passed the security inspection.

[0214] Optionally, in a specific implementation, the method further includes:

[0215] The electromagnetic signal detected by the metal detection component and the frame code data of the target mobile device are associated when the detection object carries the target mobile device through the security gate.

[0216] Optionally, in a specific implementation, the method further includes:

[0217] After the identity information of the detection object is obtained, the pass information is sent to the gate channel associated with the security gate according to the association relationship between the identity information of the detection object and the frame code data of the target mobile device, so that the gate channel is in a passable state.

[0218] Corresponding to the above-mentioned security inspection door and the above-mentioned equipment security inspection method, an embodiment of the present application also provides an equipment security inspection device.
