DETAILED DESCRIPTION

[0043] Hereinafter, the embodiments of the present application will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary, and are not intended to limit the scope of the present application. In the following detailed description, many specific details are set forth in order to provide a thorough understanding of the embodiments of the present application. However, it is apparent that one or more embodiments can be practiced without these specific details. In addition, in the following description, the description of well-known structures and techniques is omitted to avoid unnecessarily obscuring the concept of the present application.

[0044] In the related art, the entrance of a radiation area (such as a radiation protection area) is generally controlled manually by a safety officer or is provided with a common gate, which can only control the access of a person and cannot accurately detect the number of people and tailing conditions, cannot calculate the number of people entering the internal area of the nuclear radiation protection area, and cannot be linked with the safety interlock of the laboratory. Specifically, if the radiation safety problem of the beam out of the beam area is only manually controlled, the safety officer needs to invest a lot of effort in inspection and supervision, and the existing equipment does not have a precise counting function and cannot assist the work of the safety officer. The radiation area should be equipped with a safety interlock function according to the requirements of the state, and if the interlock is not ready, the beam test cannot be performed; the existing equipment does not have the function of interconnecting with the safety interlock, and cannot control the safety through the gate.

[0045] Some embodiments of the utility model provide a passage control device. The control board card is electrically connected with the safety interlock device of the radiation area, realizes the linkage of passage control and safety interlock, ensures that the beam emission is allowed only when there is no one in the radiation area, thereby significantly improving the reliability and safety of radiation protection. Moreover, the detector can accurately detect the number of pedestrians entering and leaving the radiation area each time, and the gate device and the control board card are combined to realize automatic passage control and automatic counting of the number of people in the radiation area, which can reduce the dependence on manual work and effectively reduce the radiation risk caused by human negligence.

[0046] Figure 1 The structure diagram of the passage control device according to the embodiment of the utility model is schematically shown. Figure 2 The scene diagram containing the passage control device and the radiation area from the perspective angle according to the embodiment of the utility model is schematically shown.

[0047] It should be noted that, Figure 1 and Figure 2 only as examples to which the embodiments of the utility model can be applied, to help those skilled in the art understand the technical content of the utility model, but do not mean that the embodiments of the utility model cannot include other devices, systems or structures.

[0048] As Figure 1 and Figure 2 shown, the passage control device 100 according to the embodiment can include a gate device 110, a detector 120 and a controller (not shown in the figure). The gate device 110 is used to allow pedestrians meeting the preset conditions to enter and exit the radiation area. The detector 120 is used to detect the number of pedestrians entering and exiting the radiation area each time. The controller includes a control board card, wherein the control board card is used to receive the detection result of the detector 120 to count the number of pedestrians in the radiation area. The control board card is configured to be electrically connected with the safety interlock device of the radiation area, and the control board card is further used to place the safety interlock device in a specific state for indicating the beam emission when there is no one in the radiation area.

[0049] Exemplarily, the gate device 110 comprises at least one set of fixtures, each set of fixtures comprising two oppositely arranged fixtures, each of which is configured with a rotatably connected gate. The gate device 110, as a door control device, can determine whether a preset condition is met through permission verification, and allow the pedestrian to enter or exit the radiation area after the permission verification is passed.

[0050] Exemplarily, the radiation area is arranged with an electron accelerator. When the electron accelerator is running, radiation hazards will be generated. If no control and protection is taken, radiation hazards will be caused to the surrounding personnel and environment. Most of the radiation is shielded by the effective shielding body, but the change of the running condition may also lead to the leakage of radiation to the environment outside the shielding body. When the radiation dose is greater than a certain value, a radiation accident / event will occur. Therefore, the radiation area can be defined according to the emission position of the radiation beam and the surrounding radiation dose. For example, the radiation protection area of a nuclear radiation laboratory or factory can include an X-ray machine and the surrounding radiation shielding mechanism.

[0051] Exemplarily, the detector 120 can include a passive infrared sensor. When the pedestrian passes through, the infrared transmission is blocked, thereby triggering the sensor to detect the entry and exit of the pedestrian. For example, the number of pedestrians can be determined according to the number of pedestrian triggering times.

[0052] Exemplarily, the detector 120 can include a pressure sensor. For example, a pressure sensor is laid at the entrance and exit of the radiation area. When the pedestrian steps on the sensor, the sensor will detect the change of pressure, thereby identifying the entry and exit of the pedestrian. The number of pedestrians can be determined according to the number of pressure change times.

[0053] Exemplarily, the detector 120 can include a camera. The image of the pedestrian in the image is identified through a video analysis algorithm. The entry and exit state of the pedestrian is judged by analyzing the moving track of the pedestrian. The number of pedestrians is determined by identifying the torso or head of the pedestrian.

[0054] Exemplarily, the detector 120 can include an RFID reader. An RFID reader is arranged at the entrance and exit of the radiation area. The pedestrian carries an RFID tag. When the tag enters the sensing range of the reader, the reader identifies and records the entry and exit of the pedestrian and the number of pedestrians.

[0055] Exemplarily, the detector 120 can include a laser scanner. When the pedestrian passes through, the laser is blocked, thereby triggering the laser scanner to detect the entry and exit of the pedestrian. For example, the number of pedestrians can be determined according to the number of pedestrian triggering times.

[0056] It can be understood that the detector 120 can be implemented based on existing devices, and can include one or more devices listed above, and can also include devices not listed.

[0057] Exemplarily, the control board card is responsible for processing input signals and outputting control instructions, for example, the same party can use the product: ST control board JGEA0000000-0021.

[0058] The safety interlock device includes a plurality of safety interlock components, for example, reasonably dividing the radiation area, and installing independent safety interlock components for each area. The radiation area can be divided into a plurality of independent partitions, and each partition is configured with corresponding interlock control logic. The access control device 100 can control the safety interlock components of one or more partitions, for example, when there is a person in the radiation area, all safety interlock components are placed in an open state. When there is no one in the radiation area, all safety interlock components are placed in a closed state, and at this time, the beam current is allowed to be emitted, which can be an electron beam current, which hits the target material to generate radiation, such as X-rays.

[0059] Exemplarily, the control board card is internally programmed with an algorithm that can analyze the detector 120 signal and count the real-time number of pedestrians in the radiation area, for example, one person in and one person out. In addition, the control board card is connected to the safety interlock device through an electrical interface and can send control instructions. For example, when the control board card detects that there is no one in the radiation area, it will send a signal to the safety interlock device to place it in a closed state that allows the beam current to be emitted.

[0060] According to the embodiment of the utility model, the control board card is electrically connected with the safety interlock device of the radiation area, realizing the linkage of access control and safety interlock, ensuring that the beam current is allowed to be emitted only when there is no one in the radiation area, thereby significantly improving the reliability and safety of radiation protection. And using the detector 120 can accurately detect the number of pedestrians entering and leaving the radiation area each time, and combining the gate device 110 and the control board card realizes automatic access control and automatic counting of the number of people in the radiation area, which can reduce the dependence on manual work and effectively reduce the radiation risk caused by human negligence.

[0061] In some embodiments, referring to Figure 1 and Figure 2 , the gate device 110 includes a first gate 111 and a second gate 112. The first gate 111 is electrically connected with the control board card. The second gate 112 is electrically connected with the control board card, and the second gate 112 and the first gate 111 define a passageway.

[0062] The first gate 111 is a group of fixed parts, and the second gate 112 is another group of fixed parts, and the two gates are oppositely arranged. The passageway is provided with a partition plate 113 on both sides, and the partition plates 113 on both sides and the gate of the first gate 111 and the gate of the second gate 112 form a closed passageway. When a pedestrian without permission enters the passageway, the gate can be closed to make him stay in the passageway, which is convenient for subsequent processing.

[0063] According to the embodiment of the utility model, the passage provides clear access path for the pedestrians, so that the access personnel flow orderly, effectively avoid the congestion and the confusion phenomenon to occur. Meanwhile, through the control of the gate machine arranged at both ends of the passage, the access personnel can be accurately managed, and the execution strength of the safety measures is strengthened. In addition, the number of personnel passing through each time is limited by the passage, so that the statistics of the access number becomes more accurate.

[0064] In some embodiments, referring to Figure 1 The detector 120 includes a first sensor module 121 and a second sensor module 122. The first sensor module 121 is installed on the gate device 110, and is used to detect the number of pedestrians entering the radiation area each time. And / or, the second sensor module 122 is installed on the gate device 110, and is used to detect the number of pedestrians leaving the radiation area each time.

[0065] Exemplarily, the first sensor module 121 can be installed on the first gate 111, and the second sensor module 122 can be installed on the second gate 112. The first sensor module 121 can include a first photoelectric sensor 1211 and a second photoelectric sensor 1212. Referring to Figure 1 The first photoelectric sensor 1211 and the second photoelectric sensor 1212 are arranged in sequence with respect to the passage, and can synchronously collect signals. If the first photoelectric sensor 1211 detects a pedestrian earlier than the second photoelectric sensor 1212, and the signal time difference between the two is within a reasonable range, it can be considered that the pedestrian does not follow. If the second sensor detects a pedestrian almost simultaneously or later than the first sensor, it can be considered that there is a following behavior, i.e., two or more people enter at the same time. The second sensor module 122 can include a third photoelectric sensor 1221 and a fourth photoelectric sensor 1222. Referring to Figure 1 The third photoelectric sensor 1221 and the fourth photoelectric sensor 1222 are arranged in sequence with respect to the passage, and can synchronously collect signals. If the third photoelectric sensor 1221 detects a pedestrian earlier than the fourth photoelectric sensor 1222, and the signal time difference between the two is within a reasonable range, it can be considered that the pedestrian does not follow. If the third sensor detects a pedestrian almost simultaneously or later than the fourth sensor, it can be considered that there is a following behavior, i.e., two or more people leave at the same time. The occurrence of the following behavior may exist the situation that the unauthorized personnel follow the authorized personnel to enter the radiation area irregularly, and is not conducive to the statistics of the number of people in the radiation area, so the first sensor module 121 and the second sensor module 122 can effectively detect the following behavior.

[0066] In some embodiments, referring to Figure 1The detector 120 includes a first camera 123, which includes a third camera and a first chip. The third camera is configured to capture images in the passage, and the first chip is configured to process the images to detect the number of pedestrians entering or leaving the radiation area each time.

[0067] Exemplarily, the first camera 123 can use the product of Tongfang Optics: Light Intelligent Camera F3241-E.

[0068] Exemplarily, the first camera 123 integrates the camera and the chip, and can be installed on the existing ordinary gate by a modular design. The first camera 123 itself can complete photographing, image processing and pedestrian detection, and has a low cost. The first camera 123 can be installed on the first gate 111 or the second gate 112 through a support rod, and can also be hung on the top, so that the third camera is above the passage. When a person is in the passage, the third camera can capture images of pedestrians in the passage from a bird's eye view. The first chip can run a target recognition algorithm to obtain a detection result by recognizing the number of pedestrian heads in the image. For example, the first chip runs a deep learning model, such as an algorithm based on YOLO (You Only Look Once) or SSD (Single Shot MultiBox Detector), which can quickly and accurately recognize pedestrian heads in the image and count them.

[0069] In some embodiments, the first camera 123, the first sensor module 121 and the second sensor module 122 can all be electrically connected to the control board card. The control board card can integrate the two pedestrian detection results to determine whether there is a following behavior.

[0070] In some embodiments, referring to Figure 1 The passage control device 100 further includes a first radar module 131 and / or a second radar module 132. The first radar module 131 is electrically connected to the control board card and is configured to detect the position of a pedestrian entering the radiation area each time. The second radar module 132 is electrically connected to the control board card and is configured to detect the position of a pedestrian leaving the radiation area each time.

[0071] The position of the pedestrian detected by the first radar module 131 and / or the second radar module 132 can be transmitted to the control board card. The control board card controls the first camera 123 to start detection according to the position information of the pedestrian, and can also verify the detection result of the first camera 123.

[0072] In some embodiments, referring to Figure 1 and Figure 2, the access control device 100 further comprises a first face recognition module 141 and / or a second face recognition module 142. The first face recognition module 141 is electrically connected with the control board card, and the first face recognition module 141 comprises a first camera for photographing the face of the pedestrian entering the radiation area in the forward access (i.e. the access from the first side to the second side of the radiation area) via the gate device 110. Figure 2 The second face recognition module 142 is electrically connected with the control board card, and the second face recognition module 142 comprises a second camera for photographing the face of the pedestrian leaving the radiation area in the reverse access (i.e. the access from the second side to the first side of the radiation area) via the gate device 110. Figure 2

[0073] As shown in Figure 1 and Figure 2 , the first face recognition module 141 can be installed on the second gate 112, and the first camera faces the first gate 111, i.e. the face of the pedestrian can be conveniently photographed when the pedestrian accesses in the forward direction, and then face recognition is performed. The second face recognition module 142 can be installed on the first gate 111, and the second camera faces the second gate, i.e. the face of the pedestrian can be conveniently photographed when the pedestrian accesses in the reverse direction, and then face recognition is performed.

[0074] Exemplarily, the first face recognition module 141 and / or the second face recognition module 142 can use the product IA200-T1-P10 (Type-C) of the same party.

[0075] In some embodiments, the first radar module 131 is installed on the first gate 111, and when the first radar module 131 detects that the pedestrian to be accessed into the radiation area reaches the first position, the control board card is used to respond to the signal of the first radar module 131 to open the gate of the first gate 111.

[0076] For example, the "first position" can be defined as an area 0.5-1 meters away from the entrance of the first gate 111, which is monitored by the first radar module 131. When the pedestrian enters the area, the first radar module 131 detects the presence of the pedestrian and transmits a signal to the control board card. After receiving the signal, the control board card sends an instruction to open the gate of the first gate 111 according to the preset control logic, allowing the pedestrian to enter the channel.

[0077] In some embodiments, after the pedestrian to be accessed into the radiation area enters the channel via the first gate 111, when the identification result of the first face recognition module 141 is pass, the control board card is used to control the gate of the second gate 112 to open and increase the number of pedestrians in the radiation area.

[0078] Referring to Figure 1 and Figure 2 ​, the first radar module 131 is installed at the first gate 111 of the forward passage entrance. When the radar module 131 detects that the pedestrian reaches a specific position in front of the gate, the control board card responds to the signal and triggers the gate of the first gate 111 to open, allowing the pedestrian to enter the passage. After the pedestrian enters the passage, the gate of the first gate 111 closes, and the first face recognition module 141 starts to detect the face information of the pedestrian and compares it with the database to verify the identity and authority of the pedestrian. If the identity and authority verification is successful, the gate of the second gate 112 opens, and the control board card increases the corresponding number of people in the statistical value. If the verification fails, the gate of the first gate 111 opens, the gate of the second gate 112 remains closed, and the screen of the first face recognition module 141 displays warning and prompt information, asking the pedestrian whose verification failed to leave.

[0079] In this embodiment, one or more pedestrians can be allowed to stay in the passage. In order to accurately count the number of pedestrians in the radiation area, only one pedestrian can be allowed to stay in the passage. For example, in some embodiments, when the identification result of the first face recognition module 141 is pass, and the detector 120 detects that the number of pedestrians in the passage is 1, the control board card is used to control the gate of the second gate 112 to open, and the number of pedestrians in the radiation area is increased by 1.

[0080] That is, after the pedestrian enters the passage, the gate of the first gate 111 closes, and if the identity and authority verification of the first face recognition module 141 is successful and the first camera 123 detects no following behavior, only one person is in the passage, then the control board card controls the gate of the second gate 112 to open and increases the statistical value by 1, thereby accurately counting the number of people entering the radiation area.

[0081] In some embodiments, the second radar module 132 is installed at the second gate 112. When the second radar module 132 detects that the pedestrian to be out of the radiation area reaches the second position, the control board card is used to respond to the signal of the second radar module 132 to open the gate of the second gate 112.

[0082] For example, the "second position" can be defined as an area 0.5-1 meters away from the entrance of the second gate 112, which is monitored by the second radar module 132. When the pedestrian enters this area, the second radar module 132 detects the presence of the pedestrian and transmits a signal to the control board card. After receiving the signal, the control board card sends an instruction to open the gate of the second gate 112 according to the preset control logic, allowing the pedestrian to enter the passage.

[0083] In some embodiments, after the pedestrian to be out of the radiation area enters the passage through the second gate 112, when the identification result of the second face recognition module 142 is pass, the control board card is used to control the gate of the first gate 111 to open and reduce the number of pedestrians in the radiation area.

[0084] Referring to Figure 1 and Figure 2 , the second radar module 132 is installed at the second gate 112 of the reverse passage entrance. When detecting that the pedestrian reaches a certain position in front of the gate, the control board card responds to the signal to trigger the gate of the second gate 112 to open, allowing the pedestrian to enter the passage. After the pedestrian enters the passage, the gate of the second gate 112 is closed, and the second face recognition module 142 starts to detect the face information of the pedestrian and compares it with the database to verify the identity and authority of the pedestrian. If the identity and authority verification is successful, the gate of the first gate 111 is opened, and the control board card reduces the corresponding number of people in the statistical value. If it fails, the gate of the second gate 112 is opened, and the gate of the first gate 111 remains closed, and a warning and prompt information is displayed on the screen of the second face recognition module 142, asking the pedestrian who failed to verify to exit.

[0085] The situation of identity and authority verification failure in the reverse passage process can include: 1. verified successfully via the first face recognition module 141, but there are temporary authority restrictions, the second face recognition module 142 does not capture a clear image, or the second face recognition module 142 recognizes an error, etc. 2. without successful verification by the first face recognition module 141, but enters in violation of the rules.

[0086] In this embodiment, one or more pedestrians can be allowed to stay in the passage. In order to accurately count the number of pedestrians in the radiation area, it can be specified that only one pedestrian is allowed to stay in the passage. For example, in some embodiments, when the identification result of the second face recognition module 142 is pass, and the detector 120 detects that the number of pedestrians in the passage is 1, the control board card is used to control the gate of the first gate 111 to open, and the number of pedestrians in the radiation area is reduced by 1.

[0087] That is, after the pedestrian enters the passage, the gate of the second gate 112 is closed, and if the identity and authority verification of the second face recognition module 142 is successful, and the first camera 123 detects no following behavior, there is only one person in the passage, then the control board card controls the gate of the first gate 111 to open, and the statistical value is reduced by 1, so as to accurately count the number of people leaving the radiation area, and finally combine the number of people entering and leaving the radiation area to count the number of pedestrians in the radiation area.

[0088] Figure 1 and Figure 2 The gate device 110 in the above includes the first gate 111 and the second gate 112, and the following continues to describe the passage control device 100 including the gate device 110 composed of a single third gate.

[0089] Figure 3 The scene diagram including the passage control device 100 and the radiation area from the perspective according to another embodiment of the present application is schematically shown.

[0090] In the embodiment, the access control device 100 according to the embodiment can include a gate device 110, a detector 120, and a controller (not shown in the figure). The gate device 110 is configured to allow pedestrians meeting preset conditions to enter or exit a radiation area. The detector 120 is configured to detect the number of pedestrians entering or exiting the radiation area each time. The controller includes a control board card, wherein the control board card is configured to receive the detection result of the detector 120 to count the number of pedestrians in the radiation area. The control board card is further configured to, when there is no one in the radiation area, cause a safety interlock device of the radiation area to be in a specific state indicating beam emission.

[0091] In some embodiments, as shown in Figure 3 the gate device 110 is composed of a third gate, and the third gate is electrically connected to the control board card. Compared with the gate device 110 including two or more gates, Figure 3 the gate device 110 shown in the figure can reduce the cost, reduce the complexity of hardware and software, and be easy to deploy.

[0092] In some embodiments, as shown in Figure 3 the detector 120 includes a second camera and a third camera. The second camera includes a fourth camera and a second chip, wherein the fourth camera is configured to capture a first side image of the third gate, and the second chip is configured to process the first side image to detect the number of pedestrians entering the radiation area each time. The third camera includes a fifth camera and a third chip, wherein the fifth camera is configured to capture a second side image of the third gate, and the third chip is configured to process the second side image to detect the number of pedestrians exiting the radiation area each time, wherein the first side of the third gate is farther away from the radiation area than the second side.

[0093] Exemplarily, the second camera and the third camera can be installed on the third gate, and can also be hung on the top. The fourth camera can be located at the top of the first side region in Figure 3 , and the fifth camera can be located at the top of the second side region in Figure 3 . The second camera or the third camera can use the product of the same party: light intelligent camera F3241-E. The detection process of the second chip and the third chip is the same as that of the first chip, which will not be described here.

[0094] According to the embodiment of the utility model, a single gate cooperates with two cameras (the second camera and the third camera), and is controlled by the control board card, so that the number of pedestrians entering or exiting the radiation area each time can be accurately detected, and the number of pedestrians in the radiation area can be accurately counted, the safety interlock device can be caused to be in the specific state indicating beam emission in time, and the radiation protection safety is improved.

[0095] Figure 3The detector 120 comprises a second camera and a third camera, and the following continues to explain the embodiment in which the detector 120 only comprises a single fourth camera.

[0096] Figure 4 The scene diagram of the top view angle according to another embodiment of the present application is schematically shown, which comprises the passage control device 100 and the radiation area. Figure 4 With Figure 3 The difference lies in the number of cameras included in the detector 120 and the hardware and software settings related thereto.

[0097] In some embodiments, as Figure 4 shown, the detector 120 comprises a fourth camera. The fourth camera comprises a sixth camera head and a fourth chip, and is rotatably installed on the third gate. When the fourth camera is rotated to a first orientation, the sixth camera head is used to shoot a first side image of the third gate, and the fourth chip is used to process the first side image to detect the number of pedestrians entering the radiation area each time. When the fourth camera is rotated to a second orientation, the sixth camera head is used to shoot a second side image of the third gate, and the fourth chip is used to process the second side image to detect the number of pedestrians leaving the radiation area each time, wherein the first side of the third gate is farther away from the radiation area than the second side.

[0098] Exemplarily, the fourth camera can use the product of Qifang Weishi: light intelligent camera F3241-E. The detection process of the fourth chip is the same as that of the first chip described above, and will not be repeated here.

[0099] Exemplarily, the rotating device comprises a motor and a support rod. The base of the motor is installed on the third gate, and the output end of the rotor part of the motor is connected with one end of the support rod. When the rotor of the motor rotates, it can drive the support rod to rotate around the rotating shaft of the motor. In this rotation process, the fourth camera installed on the other end of the support rod rotates synchronously to facilitate the capture of images in different directions.

[0100] For example, when the first radar module 131 detects that a pedestrian enters the first position, it will transmit this information to the control board card. The control board card analyzes the signal and determines the position of the pedestrian, and then sends a rotating instruction to the rotating device to align the fourth camera to the first side area (the first position can be within the first side area). After the fourth camera captures the image of the pedestrian, its fourth chip analyzes and feeds back the number of pedestrians to the control board card. Correspondingly, the second radar module 132 also detects the pedestrians leaving the radiation area and transmits the information to the control board card. The control board card again issues an instruction, and the rotating device adjusts the position of the fourth camera to capture the pedestrians leaving the radiation area.

[0101] It can be understood that the access control device 100 consisting of a single third gate machine can also include at least one of a safety relay, a first face recognition module, a second face recognition module, a first sensor module and a second sensor module.

[0102] The working logic of the access control device 100 is illustrated below from the perspective of control and electrical principles through one or more embodiments.

[0103] Figure 5 The schematic diagram of the control system topology of the access control device 100 is illustrated according to an embodiment of the present application. Figure 1 The schematic diagram of the control system topology of the access control device 100 is illustrated according to an embodiment of the present application. Figure 6 The schematic diagram of the electrical principle of the alarm function of the access control device 100 is illustrated according to an embodiment of the present application. Figure 7 The schematic diagram of the electrical principle related to the safety relay is illustrated according to an embodiment of the present application.

[0104] Referring to Figure 5 , the control board card is communicatively connected with the VT1 servo driver, the VT2 servo driver, the VT3 servo driver and the VT4 servo driver based on the RS485 serial communication protocol. The VT1 servo driver and the VT2 servo driver are respectively used to drive the two side gates of the first gate machine 111, and the VT3 servo driver and the VT4 servo driver are respectively used to drive the two side gates of the second gate machine 112. When only the third gate is used, two servo drivers can be configured. The control board card sends signals to the safety interlocking device based on the I / O interface, and is electrically connected with the first face recognition module 141, the second face recognition module 142 and the first camera 123 based on the I / O interface.

[0105] Figure 6 In the above Figure 3 , the first camera 123 is represented by a BX1 half-sphere camera, the first face recognition module 141 is represented by a PG01 face recognition terminal, the second face recognition module 142 is represented by a PG02 face recognition terminal, and the MCU gate controller represents the controller. It can be understood that when Figure 4 the third camera and the fourth camera are involved, two half-sphere cameras can be provided. When the rotating device is involved, the circuit of the motor can be accessed.

[0106] Figure 6, the BX1 half-ball camera, the PG01 face recognition terminal and the PG02 face recognition terminal access the DC12V power supply. When the BX1 half-ball camera detects tailing, the line between the Alarm Out A and the Alarm Out B corresponding to the BX1 half-ball camera is connected, triggering the top camera detection tailing alarm function of the MCU gate controller. When the PG01 face recognition terminal captures the face recognition, via the Alarm In A and the Alarm In B, the Out1 and the Com1 contacts corresponding to the PG01 face recognition terminal of the KF11 terminal relay are closed to form an effective signal loop, and then a face recognition comparison signal in the entrance direction is sent to the gate controller, and the gate controller will trigger the corresponding gate opening logic according to the comparison result. When the face recognition comparison fails, the line between the Alarm Out A and the Alarm Out B corresponding to the PG01 face recognition terminal is connected, triggering the entrance face recognition alarm function of the MCU gate controller. The coordination process between the PG02 face recognition terminal and the MCU gate controller is the same as the coordination process between the PG01 face recognition terminal and the MCU gate controller, and details are not repeated here.

[0107] In some embodiments, the controller further comprises a safety relay electrically connected with the control board card and a safety circuit of the radiation area (such as Figure 7 the safety protection area safety circuit in the middle of the radiation protection area), respectively, wherein the safety interlocking device is electrically connected to the safety circuit, so that the control board card is configured to be electrically connected with the safety interlocking device of the radiation area. When there is no person in the radiation area, the safety relay is used to respond to the signal of the control board card, and the safety interlocking device is placed in a specific state through the safety circuit.

[0108] In some embodiments, the access control device 100 further comprises a zero-clearing key switch 150. The zero-clearing key switch 150 is electrically connected with the control board card, wherein when the zero-clearing key switch 150 is turned, the control board card clears the number of pedestrians in the radiation area.

[0109] According to the embodiments of the present application, the zero-clearing key switch 150 is introduced into the access control device 100, and a physical means is provided to perform the zero-clearing operation. Through the zero-clearing key switch 150, the zero-clearing permission is effectively managed, and only authorized safety personnel holding the correct key can operate, which not only ensures safety and compliance, but also strengthens the supervision of safety personnel operation and increases the possibility of responsibility tracing.

[0110] In some embodiments, when there is no person in the radiation area and the zero-clearing key switch 150 is turned, the safety relay is used to respond to the signal of the control board card, and the safety interlocking device is placed in a specific state through the safety circuit.

[0111] As Figure 7As shown, the MCU gate controller and the KF10 safety relay are connected to the same DC24V power supply. Specifically, the MCU gate controller is connected to the KF10 safety relay when no one is present in the radiation area. Figure 6 None of the BX1 dome camera, PG01 face recognition terminal, or PG02 face recognition terminal issued an alarm. The equipment is in the ON state with no alarms. The D017 and COM17 contacts of the MCU gate controller and the T11 and T12 contacts of the KF10 safety relay form the signal circuit corresponding to safety input 1. After the reset key switch 150 is turned, the equipment is in the ON state and ready. The D018 and COM18 contacts of the MCU gate controller and the T21 and T22 contacts of the KF10 safety relay form the signal circuit corresponding to safety input 2. The radiation protection area safety circuit is connected to contacts 13 and 14 of the KF10 safety relay. KA1, KA2…KAn correspond to n safety interlock switches, where n is greater than or equal to 1.

[0112] The absence of alarms is safety input condition 1, and the device being ready is safety input condition 2. Both conditions being ON are necessary for the safety output to be ON, at which point the safety interlock device is placed in a specific state for indicating beam emission, such as a closed state. If this condition is not met, the safety output will not be ON, the safety interlock device will be in the open state, and no beam will be emitted.

[0113] The D019 and COM19 contacts of the MCU gate controller and the T31 and T32 contacts of the KF10 safety relay form a corresponding reset signal loop. A signal to terminal T32 that switches between OFF→ON→OFF is a necessary condition for the safety output to be ON. If this condition is not met, the safety output will not be ON. The MCU outputs a reset signal, resetting the safety output.

[0114] Combination Figures 1 to 7 The passage control device 100 of the above embodiments and the passage control device 100 are described below. The passage control method implemented based on the passage control device 100 is further described below.

And / or, the second sensor module 122 is installed on the gate device 110 to detect the number of pedestrians who leave the radiation area each time.

[0124] In some embodiments, the passage is defined between the first gate 111 and the second gate 112.

[0125] In some embodiments, the third camera of the first camera 123 takes an image in the passage, and a first chip of the first camera 123 processes the image to detect the number of pedestrians who enter or leave the radiation area each time.

[0126] In some embodiments, the first radar module 131 is electrically connected with the control board card to detect the position of the pedestrian who is about to enter the radiation area each time. And / or, the second radar module 132 is electrically connected with the control board card to detect the position of the pedestrian who is about to leave the radiation area each time.

[0127] In some embodiments, the first radar module 131 is installed on the first gate 111, and when the first radar module 131 detects that the pedestrian who is about to enter the radiation area reaches the first position, the control board card is used to control the first gate 111 to open the gate in response to the signal of the first radar module 131.

[0128] In some embodiments, after the pedestrian to be entered into the radiation area enters the passage via the first gate 111, when the identification result of the first face recognition module 141 is pass, the control board card controls the gate of the second gate 112 to open, and the number of pedestrians in the radiation area is increased.

[0129] In some embodiments, when the identification result of the first face recognition module 141 is pass, and the detector 120 detects that the number of pedestrians in the passage is 1, the control board card controls the gate of the second gate 112 to open, and the number of pedestrians in the radiation area is increased by 1.

[0130] In some embodiments, the second radar module 132 is installed on the second gate 112, and when the second radar module 132 detects that the pedestrian to be left the radiation area reaches the second position, the control board card is used to open the gate of the second gate 112 in response to the signal of the second radar module 132.

[0131] In some embodiments, after the pedestrian to be left the radiation area enters the passage via the second gate 112, when the identification result of the second face recognition module 142 is pass, the control board card controls the gate of the first gate 111 to open, and the number of pedestrians in the radiation area is reduced.

[0132] In some embodiments, when the identification result of the second face recognition module 142 is pass, and the detector 120 detects that the number of pedestrians in the passage is 1, the control board card controls the gate of the first gate 111 to open, and the number of pedestrians in the radiation area is reduced by 1.

[0133] In some embodiments, the gate device 110 is composed of a third gate, and the third gate is electrically connected with the control board card.

[0134] In some embodiments, the detector 120 includes a second camera and a third camera. The second camera includes a fourth camera head and a second chip. The third camera includes a fifth camera head and a third chip. The fourth camera head is used to shoot a first side image of the third gate, and the second chip is used to process the first side image to detect the number of pedestrians entering the radiation area each time. The fifth camera head is used to shoot a second side image of the third gate, and the third chip is used to process the second side image to detect the number of pedestrians leaving the radiation area each time, wherein the first side of the third gate is farther away from the radiation area than the second side.

[0135] In some embodiments, the detector 120 comprises a fourth camera. The fourth camera comprises a sixth camera head and a fourth chip, and is rotatably installed on the third gate machine. When the fourth camera rotates to a first orientation, the sixth camera head captures a first side image of the third gate machine, and the fourth chip is used to process the first side image to detect the number of pedestrians entering the radiation area each time.

[0138] Figure 9 A flowchart of a passage control method according to another embodiment of the present application is schematically shown.

[0139] In operation S901, after initialization, it is confirmed that the nuclear radiation protection area (i.e. the radiation area) is empty, the safety officer turns the "zero-clearing ready key switch", and the device is ready. When there is no one in the passage, the gate is kept closed.

[0140] In operation S902, to ensure the accuracy of counting, only one person is allowed to enter the nuclear radiation protection area each time: referring to Figure 1 and Figure 2 When the person is at the entrance position of the gate machine (#1 gate), the #1 gate is sensed to open, the person enters the passage, 1:N face comparison is performed in the passage, and the number of people is detected by the top camera. If the face comparison is successful and the number of people is one, the #2 gate is opened, the person walks out of the passage to complete a forward passage, and the count is increased by one. If the person is unauthorized or the number of people is greater than one, the device alarms, the #1 gate is opened in reverse, the excess person exits the passage, and the count is not increased. When the number of people in the nuclear radiation protection area is not zero, the safety interlocking is disconnected, and the X-ray machine in the nuclear radiation protection area is not allowed to emit beams.

[0141] In operation S903, when the personnel is at the exit position of the gate (in front of the #2 gate), the #2 gate is induced to open, the personnel enters the channel, 1:N face comparison is performed in the channel, and the top camera performs personnel quantity detection. If the face comparison is successful and the personnel quantity is 1, the #1 gate is opened, the personnel walks out of the channel to complete one reverse passage, and the count is reduced by 1. If the face comparison is unsuccessful, the personnel exits the channel and contacts the staff. When the personnel count in the nuclear radiation protection area is 0, the safety interlock is ready, and the X-ray machine in the nuclear radiation protection area is allowed to emit a beam.

[0142] In combination Figure 9 , and with reference still to Figure 1 and Figure 2 , the passage control device includes exit and entrance 2 face recognition modules, detectors, radar modules and sensor modules, gates and their drive modules. The face recognition module is used for checking the access permission of personnel, releasing authorized personnel and intercepting unauthorized personnel. The detector can detect whether the personnel entering the inside of the gate channel is one person. If there are more than one person, an alarm is sounded and the gate is opened to make the excess personnel exit the channel, ensuring the accuracy of the count.

[0143] The face recognition module, the detector, and the control board card count function linkage automatically intercept unauthorized personnel and release authorized personnel and count. There is also an audible and visual prompt module (such as Figure 1 the first indicator light 161 and the second indicator light 162 in the first indication light 161) for guiding and prompting personnel to pass through, which can effectively prevent unauthorized personnel and trailing personnel from entering the nuclear radiation protection area.

[0144] In some embodiments, a temperature measurement intelligent terminal management system can be configured, installed in a server, and integrated in the face recognition module of the gate. The face recognition module can add, delete, modify, and query personnel permissions, query historical information, and obtain the temperature of the passing personnel.

[0145] In some embodiments, a remote control module can be configured. When a device fails or other events that require manual handling occur, the remote control can be used to open the gate panel. At this time, the passing personnel is not counted.

[0146] In some embodiments, a count display can be configured to display the number of personnel in the current radiation area through the screen.

[0147] In some embodiments, the face recognition module can be replaced by a face recognition camera or an IC card reader, an identity card reader, or other information acquisition modules that can be used to identify personnel.

[0148] According to one or more embodiments of the utility model, in order to protect high-risk radiation workplace personnel safety, reduce the risk of radiation accident / event, utilize face recognition and other technical means, have the access radiation workplace personnel authority management and radiation workplace personnel quantity statistics function in, effectively avoid the occurrence of radiation accident / event.Not only realizes the automation control of personnel passage, still through the automatic statistics and display of the number of people in the nuclear radiation protection area, avoids the additional management personnel demand, thereby the manual cost is saved obviously.In addition, by combining the counting function with the safety interlock mechanism, it is ensured that the beam operation cannot be performed in the protection area when the count is not zero, greatly improving the safety.The modular design adopted allows users to flexibly configure the detector, the count display and the face recognition module according to their own needs, and the compatibility with the existing gate machine further reduces the material cost.Meanwhile, the application of non-inductive detection technology improves the experience of the detected person and avoids the time wasted due to manual detection.
