[0008] In some embodiments, the first mounting bracket and the second mounting bracket are an integrated structure, or the first mounting bracket and the second mounting bracket are connected by a connecting mechanism.
[0009] In some embodiments, the first mounting bracket includes adjacent first connecting sides and second connecting sides, and the second mounting bracket includes a plurality of first mounting portions and a plurality of second mounting portions; at least a portion of the first mounting portions and the first connecting sides are connected by first adjustment structures spaced apart in the height direction of the first connecting sides; at least a portion of the second mounting portions and the second connecting sides are connected by second adjustment structures spaced apart in the height direction of the second connecting sides; the connecting mechanism includes the first adjustment structure and the second adjustment structure.
[0010] In some embodiments, the first connecting side and the second connecting side are perpendicular, and the first mounting portion and the second mounting portion are perpendicular.
[0011] In some embodiments, the first adjustment structure includes a first adjustment hole, and the second adjustment structure includes a second adjustment hole, wherein at least one of the second adjustment hole and the first adjustment hole is a waist-shaped hole.
[0012] In some embodiments, the first mounting bracket includes a front bracket; the front bracket includes a first connecting side and a second connecting side, and the front bracket is inclined outward relative to the second mounting bracket toward the second security checkpoint.
[0013] In some embodiments, the second mounting bracket includes a bracket body and a plurality of support members, each of the support members spanning the bracket body in the width direction and connected to the bracket body; the plurality of support members are spaced apart in the height direction of the bracket body; each support member includes a first mounting portion and a second mounting portion.
[0014] In some embodiments, the first mounting bracket includes a front frame, and the second mounting bracket includes a slot; the detection device includes a transparent plate facing the first detection component; the transparent plate includes a first side and a second side opposite to each other, the first side being inserted into the slot; the second side being magnetically attracted to the front frame.

[0017] Since the detection device includes a first imaging device, a second imaging device, a first metal detection device, and a second metal detection device, the first and second imaging devices can be used to detect at least one piece of information such as the position, outline, speed, trajectory, and behavioral intent of the inspected object to determine whether there are suspicious items in the inspected object. The first and second metal detection devices can cooperate to detect at least one piece of information such as whether the inspected object has metal objects (not limited to small metal objects) and the size of the metal objects, which makes up for the limited metal detection capabilities of the first and second imaging devices. Thus, the detection device can fuse the detection results of the two to obtain the final result. Not only can it detect more types of items, but fusing the detection results of the two makes the detection effect better and more accurate, especially in detecting small metal objects such as keys or belt buckles.

[0031] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.
[0032] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.
[0033] See Figures 1 to 3 , Figure 8 and Figure 12This application discloses a detection device. The detection device includes a first imaging device 1, a second imaging device 2, a first metal detector 14, and a second metal detector 24. In some embodiments, the detection device also includes a pedal 3. The first imaging device 1 and the second imaging device 2 cooperate to form a first security check channel 101. The structure of the first security check channel 101 is sufficient to allow pedestrians to pass through, and is not limited to the unequal width shape shown in the figure. For example, the first security check channel 101 can be a channel of equal width along the passage direction R. Both the first imaging device 1 and the second imaging device 2 include a first mounting frame 11 and a first detection component 12. The first detection component 12 is disposed within the first mounting frame 11. It should be noted that, generally, the structure of the first mounting frame 11 of the first imaging device 1 is the same as that of the first mounting frame 11 of the second imaging device 2, but in some cases, their structures may be different. The structure of the first detection component 12 is not limited, as long as it can achieve imaging. For example, the first detection component 12 may include a planar array millimeter-wave antenna array, and the detection implementation principle of the planar array millimeter-wave antenna array can refer to existing technology principles; or, the first detection component 12 may be a combination of various components, such as a 3D ToF (Time of Flight) camera, a low-frequency microwave radar module, a thermal imaging camera, and a high-precision infrared light curtain array. Typically, the number of first detection components 12 in the first imaging device 1 is equal to the number of first detection components 12 in the second imaging device 2, and their individual numbers are not limited, as long as they can achieve the purpose of imaging and detection. For example, in the case where the first detection component is a planar array millimeter-wave antenna... Figure 1 , Figure 2 and Figure 6 The electromagnetic waves of the first detection component 12 pass through one of the three transparent plates 50 shown, thus it can be inferred that the number of the first detection components 12 is three. In other embodiments, the first detection component 12 of each of the first imaging device 1 and the second imaging device 2 on each side of the detection device may also be only one, two, etc.
[0034] See Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 and Figure 12The first imaging device 1 has a first metal detection device 14 at one end, and the second imaging device 2 has a second metal detection device 24 at one end. The "setup" includes the following situations: 1) the first imaging device 1 and the first metal detection device 14 are connected as one unit; the second imaging device 2 and the second metal detection device 24 are connected as one unit; 2) the first imaging device 1 and the first metal detection device 14 are not connected, for example, they are close together or separated by a certain distance, and the second imaging device 2 and the second metal detection device 24 are also not connected; however, this "lack of connection" does not affect the detection result. Regardless of whether they are connected, the first metal detection device 14 and the second metal detection device 24 cooperate to form a second security check channel 102, and the second security check channel 102 is connected to the first security check channel 101. Taking the direction of passage R as a reference, after connection, one implementation is that pedestrians first pass through the second security check channel 102, and then through the first security check channel 101 (referred to as metal detection in front, imaging detection device behind). More specifically, in... Figure 2 and Figure 6 In this configuration, the first metal detector 14 is located at the right end of the first imaging device 1; the second metal detector 24 is located at the right end of the second imaging device 2. In other embodiments, pedestrians first pass through the first security checkpoint 101 and then through the second security checkpoint 102 (referred to as imaging detection device in front, metal detector behind), for example, […]. Figure 2 and Figure 6 In this process, the position of the first metal detection device 14 is changed to the left end of the first imaging device 1, and the position of the second metal detection device 24 is changed to the left end of the second imaging device 2.
[0035] Taking a metal detector preceding an imaging detection device as an example, the operation of the detection equipment is illustrated below: Specifically, using the first metal detector 14 as the transmitting device and the second metal detector 24 as the receiving device, a pedestrian passing through the entrance triggers the front light barrier module 191, simultaneously triggering metal detection and imaging detection (i.e., the imaging detection device performs detection). The processor of the detection equipment intercepts and analyzes the signal from the second metal detector 24 within a certain period before the front light barrier module 191 is triggered. As the pedestrian passes through, the rear light barrier module 192 is triggered. The processor then intercepts the signals from the first imaging device 1 and the second imaging device 2, analyzes the imaging images from the triggering of the front light barrier module 191 to the triggering of the rear light barrier module 192 in real time, and outputs the results. The final result of the detection equipment is the fusion of the two signals. In this process, because the signal from the second metal detector 24 is intercepted first, the detection signal generated by the second metal detector 24 during the subsequent passage of the pedestrian, due to vibrations or other reasons, will not be intercepted, and the processor will not process this signal. Therefore, it helps to avoid interference from other signals to metal detection and improves detection accuracy. The vibration described above can be explained in the following ways: When the first metal detector 14 and the second metal detector 24 are connected to the pedal 3, a pedestrian passing through the detection device causes the pedal 3 to vibrate, and the vibration of the pedal 3 causes the first metal detector 14 and the second metal detector 24 to vibrate; if there is no pedal 3, vibration may also be caused by other reasons (such as a pedestrian or luggage accidentally bumping into the first metal detector 14 or the second metal detector 24).
[0036] In practical applications, the working sequence of metal detection and imaging detection can be reasonably deployed according to security inspection requirements. Furthermore, the effective detection signal in the metal detection and imaging detection process can be reasonably determined by utilizing the triggering timing of the light barrier module, so as to ensure the reliability of the detection results.
[0037] In security inspection scenarios, the combined detection equipment disclosed in the embodiments of this application can efficiently detect whether pedestrians are carrying suspicious items during pedestrian passage, and can meet the detection of various types of suspicious items, combining detection accuracy and detection efficiency.
[0038] See Figure 3 , Figure 8 , Figure 11 and Figure 12 Both the first metal detector 14 and the second metal detector 24 include a second mounting bracket 242 and a second detection component 241. The second detection component 241 is disposed within the second mounting bracket 242. Figure 3 , Figure 8 and Figure 11The second detection component 241 of the second metal detection device 24, as shown, includes a receiving coil assembly. Figure 12 The diagram illustrates that the second detection component 241 of the first metal detector 14 includes a transmitting coil assembly. In other embodiments, the second detection component 241 of the second metal detector 24 includes a receiving coil assembly, and the second detection component 241 of the first metal detector 14 includes a transmitting coil assembly. In still other embodiments, both the second detection component 241 of the first metal detector 14 and the second metal detector 24 include a transmitting coil assembly and a receiving coil assembly. See also... Figure 8 , Figure 9 , Figure 11 and Figure 12 Both the transmitting coil assembly and the receiving coil assembly include a coil, multiple conical rubber plugs 2412, and a mounting component 2413. For clarity, see [link to documentation]. Figure 9 The coil of the transmitting coil assembly is marked as transmitting coil 1411, see [link / reference]. Figures 6 to 8 The coil of the receiving coil assembly is designated as receiving coil 2411. In this application, the transmitting coil 1411 of the transmitting coil assembly includes a first transmitting coil 1411a and a second transmitting coil 1411b. The coil 2411 of the receiving coil assembly also includes a first receiving coil 2411a and a second receiving coil 2411b. A plurality of the conical rubber plugs 2412 are mounted on a mounting member 2413. The shape and structure of the mounting member 2413 are not limited; for example, the mounting member 2413 can be a plate-shaped sheet metal part. The plurality of conical rubber plugs 2412 are sequentially connected to form a closed loop, and the loop is not limited to the rectangle shown in the figure. The coil is wound around the plurality of conical rubber plugs 2412. Figures 6 to 8 The diagram illustrates four sets of first receiving coils 2411a and four sets of second receiving coils 2411b. Correspondingly, Figure 9 The diagram illustrates four sets of first transmitting coils 1411a and four sets of second transmitting coils 1411b. As described above, since the multiple conical rubber plugs 2412 are sequentially connected to form a closed loop, the coils are wound around the multiple conical rubber plugs 2412, thus forming a undulating coil. When the transmitting coil assembly and receiving coil assembly cannot be zeroed due to a large surrounding metal frame, the coils are wound around the conical rubber plugs 2412. Each turn of the coil has a different diameter. By physically moving the position or shape of the coil, the strength and phase of the induced magnetic field are changed. This generates a "compensation signal" on the coil that is equal in magnitude and opposite in direction to the "useless signal," thereby canceling the useless signal to zero. This solves the problem of being unable to zero due to large surrounding metal, suppresses background noise or interference, and retains only the target signal to be detected. Of course, if there is no large metal frame around the transmitting coil assembly or receiving coil assembly, either the second metal detection device 24 or the first metal detection device 14 can also adopt the aforementioned design.
[0039] The following describes one working mode of the detection device: The detection device includes a processor (unlabeled), which is connected to the first imaging device 1, the second imaging device 2, the first metal detection device 14, and the second metal detection device 24, and is at least used to receive their signals. The processor fuses the received signals to obtain a detection result. For example, the processor determines whether there are metal objects in the inspected object and the size of the metal objects based on the signals from the first metal detection device 14 and the second metal detection device 24. Combining the images obtained by the first imaging device 1 and the second imaging device 2, the processor obtains at least one piece of information from the images, such as the position, outline, speed, trajectory, and behavioral intent of the inspected object, to determine whether there are suspicious items in the inspected object. Furthermore, it determines whether to release or not to release the object. More specifically, for example, if the detection result of the detection device determines that the metal is only a small metal such as a belt buckle or a key, then the object can be released; if the metal is determined to be a controlled knife, then the object cannot be released.
[0040] As described above, the detection device includes a first imaging device 1, a second imaging device 2, a first metal detection device 14, and a second metal detection device 24. The detection working principles of the first imaging device 1 and the second imaging device 2 are different from those of the first metal detection device 14 and the second metal detection device 24. The device can detect at least one piece of information such as the position, outline, speed, trajectory, and behavioral intention of the object being inspected through the images acquired by the first imaging device 1 and the second imaging device 2. The first metal detection device 14 and the second metal detection device 24 work together to detect at least one piece of information such as whether there are metal objects (not limited to small metal objects such as belt buckles and keys) in the object being inspected and the size of the metal objects. This compensates for the limited detection capabilities of the first imaging device 1 and the second imaging device 2 for metal objects. Thus, the detection device can fuse the detection results of the two devices to obtain the final result. This not only allows for the detection of more types of objects, but also improves the detection effect and accuracy by fusing the detection results of the two devices, especially for detecting small metal objects such as keys or belt buckles.
[0041] There are several possible relationships between the first mounting bracket 11 and the second mounting bracket 242. For example, the first mounting bracket 11 and the second mounting bracket 242 can be an integrated structure, or the first mounting bracket 11 and the second mounting bracket 242 can be connected by a connecting mechanism. The connecting mechanism is not limited to the structure described below, as long as it can connect the first mounting bracket 11 and the second mounting bracket 242.
[0042] The following describes some implementations of the first mounting bracket 11 and the second mounting bracket 242 being connected by a connecting mechanism.
[0043] See Figure 6 and Figure 7 The first mounting bracket 11 includes adjacent first connecting side 111 and second connecting side 112, see [link / reference]. Figure 8 , Figure 10 and Figure 12 The second mounting bracket 242 includes a plurality of first mounting portions 24221 and a plurality of second mounting portions 24222. Figure 10 The diagram illustrates a first mounting portion 24221 and a second mounting portion 24222 disposed on the same support member 24222. The first mounting portion 24221 and the second mounting portion 24222 can also be disposed on different components. At least a portion of the first mounting portion 24221 and the first connecting side 111 are connected by a first adjustment structure spaced apart in the height direction of the first connecting side 111; at least a portion of the second mounting portion 24222 and the second connecting side 112 are connected by a second adjustment structure spaced apart in the height direction of the second connecting side 112; the connecting mechanism includes the first adjustment structure and the second adjustment structure. The first adjustment structure and the second adjustment structure are used to adjust the relative position between the second mounting bracket 242 and the first mounting bracket 11, and their structures are not limited. Figure 7 and Figure 10 In the first adjustment structure, there are a first adjustment hole 24223, a first nut 44 and a first bolt 43, and the second adjustment structure includes a second adjustment hole 24224, a second nut 46 and a second bolt 45.
[0044] As described above, since the first connecting side 111 and the first mounting part 24221 are connected by the first adjusting structure, and the second connecting side 112 is connected by the second adjusting structure, the first connecting side 111 and the second mounting part 24222 are connected by the second adjusting structure. Because the first connecting side 111 and the second connecting side 112 are adjacent, they can position the second mounting frame 242. For example, they can position the first mounting frame 11 and the second mounting frame 242 in the lateral direction. In addition, the adjusting function of the first adjusting structure and the second adjusting structure can adjust the relative position of the first mounting frame 11 and the second mounting frame 242 in the height direction. After adjustment, the first adjusting structure and the second adjusting structure lock the first mounting frame 11 and the second mounting frame 242. Therefore, the combination of lateral positioning and height adjustment makes it easy to assemble the first mounting frame 11 and the second mounting frame 242.
[0045] See Figure 7 and Figure 10 The first connecting side 111 and the second connecting side 112 are perpendicular, and the first mounting part 24221 and the second mounting part 24222 are perpendicular.
[0046] As described above, the vertical relationship makes the right angle the positioning part, which has a better positioning effect and does not require an additional positioning structure. Positioning is achieved by utilizing the structure of the first mounting bracket 11 and the second mounting bracket 242 themselves. The structures of the first mounting bracket 11 and the second mounting bracket 242 are simple.
[0047] See Figure 7 and Figure 10 Both the first adjustment hole 24223 and the second adjustment hole 24224 are oblong holes. Technicians can understand that as long as at least one of the first adjustment hole 24223 and the second adjustment hole 24224 is an oblong hole, it is acceptable.
[0048] As set up above, at least one of the first adjustment hole 24223 and the second adjustment hole 24224 is an oblong hole, which facilitates the adjustment of the position between the first mounting bracket 11 and the second mounting bracket 242.
[0049] See Figure 6 and Figure 7 The first mounting bracket 11 includes a front bracket 113. The front bracket 113 includes a first connecting side 111 and a second connecting side 112. The front bracket 113 is inclined towards the outside of the second security check channel 102 relative to the second mounting bracket 242. After inclination, the angle between the front bracket 113 and the passage direction is m, where m can be an obtuse angle.
[0050] As described above, since the front frame 113 is tilted outward toward the second security check channel 102, it is advantageous that the first imaging device 1 and the second imaging device 2 each include multiple first detection components 12, and these first detection components 12 can be oriented in different directions, thereby avoiding missed detections.
[0051] See Figure 8 and Figure 12 The second mounting bracket 242 is frame-shaped, and the frame shape is not limited. The frame shape of the second mounting bracket 242 can position the second detection component 241 on the one hand, and has high strength on the other hand. These two aspects can ensure that the second detection component 241 is not easy to loosen and can provide a more stable signal.
[0052] See Figure 8 and Figure 12 The second mounting bracket 242 includes a bracket body 2421 and multiple support members 2422. Each support member 2422 spans the bracket body 2421 across its width and is connected to it. The multiple support members 2422 are spaced apart along the height of the bracket body 2421. Each support member 2422 includes a first mounting portion 24221 and a second mounting portion 24222.
[0053] As described above, the second mounting bracket 242 includes a bracket body 2421 and a support member 2422 that spans the bracket body 2421 in the width direction. The second mounting bracket 242 has high structural strength.
[0054] See Figure 7 and Figure 6 The first mounting bracket 11 includes a front frame 113, and the second mounting bracket 242 includes a slot 244. The shape of the slot 244 is not limited; in this application, the slot 244 is surrounded by a first enclosure 47, a second enclosure 48, and a third enclosure 49. The detection device includes a wave-transparent plate 50 directly opposite the first detection component; the wave-transparent plate 50 includes a first side and a second side opposite to each other, the first side being inserted into the slot 244; the second side being magnetically attracted to the front frame 113.
[0055] As described above, for the wave-transparent plate 50, the first side is inserted into the slot 244; the second side is magnetically attracted to the front frame 113, which can remove the fixing screws on the exterior surface of the testing equipment and prevent the wave-transparent plate 50 from tipping over due to insufficient magnetic fixation. Furthermore, the second mounting bracket 242 includes the slot 244, which can reduce the number of separate slot components, and the second mounting bracket 242 has a more integrated and aesthetically pleasing appearance.
[0056] See Figure 1 , Figure 2 , Figure 3 and Figure 6 The first mounting frame 11 includes a front frame 113, a middle frame 114, and a rear frame 115; the front frame 113 and the rear frame 115 are symmetrically located at opposite ends of the middle frame 114, and are distributed at obtuse angles to the middle frame 114. The front frame 113, the middle frame 114, and the rear frame 115 are respectively provided with the first detection component 12.
[0057] As described above, since the front frame 113 and the rear frame 115 are symmetrically located at opposite ends of the intermediate frame 114 and are distributed at obtuse angles to the intermediate frame 114 respectively, they form the upper base and waist of an isosceles trapezoid. The orientations of their respective second detection components 241 are different, thus the detection range is wide and missed detections are avoided.
[0058] See Figure 2 , Figure 3 and Figure 4Taking the pedestrian's forward-to-back traffic direction as a reference, the first mounting frame 11 includes a first end 271 relative to the second mounting frame 242. The structure of the first end 271 is not limited, for example, it can be a column. The second mounting frame 242 includes a second end 272 relative to the first mounting frame 11. The structure of the first end 271 is not limited, for example, it can be a column. At least one of the first end 271 of the first imaging device 1, the first end 271 of the second imaging device 2, the second end 272 of the first metal detection device 14, and the second end 272 of the second metal detection device 24 includes a light strip mounting slot. The detection device includes light strip assemblies 28, and the number of light strip assemblies 28 is equal to the number of light strip mounting slots.
[0059] See Figure 3 and Figure 4 The light strip assembly 28 includes a light strip, a lampshade 281, and a light strip fixing plate 282. In some embodiments, the light strip assembly 28 may not include the light strip fixing plate 282. When the light strip fixing plate 282 is included, the light strip is adhered to the light strip fixing plate 282 by adhesive. The lampshade 281 is detachably assembled with the corresponding first end or second end, and in the assembled state, covers the light strip mounting groove. The detachable assembly can be done in various ways, such as the lampshade 281 being snapped onto the first end 271 or the second end 272, but is not limited to this. Although the above embodiment illustrates the installation of the light strip assembly 28 with the second end 272, the assembly of the light strip assembly 28 with the first end 271 can also be done in this manner.
[0060] As described above, since the lamp cover 281 is detachably assembled with the first end 271 or the second end 272, the lamp strip can be exposed by removing the lamp cover 281, which allows for quick and convenient maintenance of the lamp strip. Therefore, the testing equipment can be maintained quickly and conveniently.
[0061] See also Figure 8 , Figure 12 and Figure 2 The detection equipment includes decorative panels 243, and there are multiple decorative panels 243. Both the first metal detection device 14 and the second metal detection device 24 include decorative panels 243. Due to the viewing angle, Figure 2 Only the decorative panel 243 of the first metal detector 14 is marked. Both the decorative panel 243 and the second detection component 241 are inserted from the top of the second mounting bracket 242. Subsequently, the second detection component 241, the decorative panel 243, and the second mounting bracket 242 are secured together with screws. After installation, the position of the decorative panel 243 can be seen in [reference needed]. Figure 2 The method of locking them together is not limited. The edge of the decorative panel 243, the edge of the mounting part 2413 of the second detection component 241, and the second mounting bracket 242 are respectively provided with screw holes. Screws pass through the screw holes to lock them together.
[0062] See Figure 2 and Figure 3 The second imaging device 2 includes a receiving cavity, an interface plate, and a flip cover 21. Those skilled in the art will understand that either the first imaging device 1 or the second imaging device 2 may include the receiving cavity, the interface plate, and the flip cover 21, with the interface plate located within the receiving cavity. The interface plate is not limited; for example, it may include a power interface, a USB interface, or other communication interfaces. The flip cover 21 is rotatably connected to the side wall of the receiving cavity, and may also be rotatably connected to other components of the detection equipment, such as… Figure 3 and Figure 5 In this device, the testing equipment includes a base plate 22. A pivot hole 221 is provided on the base plate 22, and a flip cover 21 is rotatably connected to the pivot hole 221. After rotatable connection, the flip cover 21 rotates in a first direction to open the receiving cavity, and rotates in a second direction opposite to the first direction to cover the receiving cavity. (See also...) Figure 2 and Figure 3 It can be seen that both the first direction and the second direction can be horizontal, but in opposite directions. In other embodiments, both the first direction and the second direction can also be vertical, but in opposite directions.
[0063] As described above, by opening or covering the receiving cavity in different directions with the flip cover 21 to expose the interface board, the interface board or the testing equipment can be easily or quickly maintained.
[0064] In some embodiments, a magnet is provided inside the receiving cavity, and the flip cover 21 is attracted to the magnet. This arrangement makes it easier to install the flip cover 21 through magnetic attraction.
[0065] In some implementations, see Figure 2 and Figure 3 With the pedestrian flow direction from front to back as a reference, the flip cover 21 and the interface plate are located at the rear of the detection device. This configuration ensures that the flip cover 21, being at the rear of the detection device, does not obstruct pedestrian traffic during device maintenance.
[0066] See Figure 1 , Figure 2 and Figure 3 The first imaging device 1 and the second imaging device 2 both include multiple door panels, and their respective first mounting frames 11 include a front frame 113, a middle frame 114, and a rear frame 115. In this case, the structure formed by the front frame 113, the middle frame 114, and the rear frame 115 is not limited to... Figure 2 The upper base and legs of the isosceles trapezoid shown are illustrated. For clarity, only the upper base and legs are shown. Figure 2 and Figure 3The front door panel 231, middle door panel 232, and rear door panel 233 of the second imaging device 2 are marked. These door panels are detachably assembled with their corresponding front frame 113, middle frame 114, and rear frame 115. In the assembled state, the door panels and the corresponding frame form cavities to accommodate components of the detection equipment. For example, the three door panels of the first imaging device 1, together with the front frame 113, middle frame 114, and rear frame 115, form three cavities, each containing a planar array millimeter-wave antenna array. These cavities of the first imaging device 1 or the second imaging device 2 may or may not be interconnected. Figures 1 to 3 It also shows that each cavity is covered by a top cover 25. Figures 1 to 3 The first imaging device 1 and the second imaging device 2 of the detection equipment each include three top covers 25. The shape of the top cover 25 is determined by the shape of the cavity opening of each cavity, and they may be the same or different.
[0067] As described above, the door panel and the first mounting bracket 11 can be detachably assembled. In the assembled state, the door panel and the corresponding front frame 113, middle frame 114 and rear frame 115 of the first mounting bracket 11 form a cavity, which allows for convenient and quick maintenance of the testing equipment and facilitates the installation of the testing equipment. For example, the corresponding door panel can be removed to maintain the components inside the cavity. Or, for example, in this application, the front door panel 231 can be installed first, then the middle door panel 232 can be installed, and finally the rear door panel 233 can be installed.
[0068] See Figure 2 , Figure 3 and Figure 5 The testing equipment includes a base plate 22. Figure 5 The diagram shows that the base plate 22 includes a positioning part 222, suggesting that the door panel includes a positioning hole. Alternatively, the base plate 22 could include a positioning hole, and the door panel could include the positioning part 222. In short, either the base plate 22 or the door panel needs to include the positioning part 222, and the other needs to include a positioning hole. The positioning part 222 is inserted into the positioning hole.
[0069] As described above, by setting up a positioning part 222 and a positioning hole, and by inserting the positioning part 222 into the positioning hole, the installation of the door panel is convenient and easy, and correspondingly, the maintenance of the testing equipment is convenient and quick.
[0070] See Figure 2 and Figure 3The cavity is defined with reference to the direction of pedestrian movement from front to back; the cavity includes a rear cavity 26; the detection device includes a motherboard 261, a communication module, and a power module. The motherboard integrates the processor. In some cases, the communication module and power module can also be integrated on the motherboard 261. The motherboard 261, the communication module, and the power module are located within the rear cavity 26. Of course, in addition to the aforementioned motherboard 261, communication module, and power module, other modules of the detection device can also be located within the rear cavity 26.
[0071] As described above, the main modules, such as the motherboard, communication module, and power module, are all located within the rear cavity 26, allowing for quick and convenient maintenance should the testing equipment malfunction.
