Description

Technical Field

[0001] This utility model relates to the field of inductive loop installation technology, and in particular to an inductive loop module and vehicle management system. Background Technology

[0002] Inductive loop detectors are mainly used in parking lots, intersections, toll booths, and other similar locations to detect the presence of vehicles. When a vehicle passes over or stops above the loop, it disturbs the magnetic field around the loop, causing a change in the loop's inductance. By monitoring this change in inductance, it is possible to effectively identify whether a vehicle has passed over or stopped above the inductive loop.

[0003] Inductive loops are typically buried in the ground in places where vehicle detection is required, such as parking lots, intersections, and toll stations. In the traditional installation method, it is necessary to first cut a groove in the ground, then lay the inductive loop in the groove, and finally fill the groove with sealant. After the sealant cures, the inductive loop is fixed in the groove, and the installation of the inductive loop is completed.

[0004] However, in the above method, on the one hand, it is necessary to cut the wire groove in the ground, which not only increases the construction and installation cost, but also damages the integrity of the ground. On the other hand, after the inductive coil is laid in the wire groove, it is necessary to wait for the sealant to cure before it can be used, which prolongs the installation cycle of the inductive coil. Utility Model Content

[0005] The present invention aims to provide a ground loop module and vehicle management system to solve the technical problems in the prior art where the installation of ground loops damages the integrity of the ground and has high installation costs and long installation cycles.

[0006] The present invention addresses its technical problem by providing the following technical solution: a ground induction coil module, comprising:

[0007] The mounting base is capable of being fixedly engaged with an external object, and the mounting base is provided with a wire groove;

[0008] A ground inductive coil is disposed in the groove.

[0009] In some embodiments, the mounting base is further provided with a mounting groove on the side facing the external fixture, the mounting groove being filled with a first adhesive, and the mounting base and the external fixture being fixedly connected by the first adhesive.

[0010] In some embodiments, the mounting base is a ring-shaped structure, and there are multiple mounting slots pointing from the center of the mounting base to its edge. The multiple mounting slots are spaced apart, and the groove is disposed between two adjacent mounting slots.

[0011] In some embodiments, a first protrusion is provided on the inner sidewall of the mounting groove, and a second protrusion is provided on the inner sidewall of the wire groove.

[0012] In some embodiments, the first protrusion is a trapezoidal protrusion, the top surface of which is connected to the inner wall of the mounting groove, and the bottom surface of which faces the center of the mounting groove.

[0013] In some embodiments, the mounting base further includes ribs, and a plurality of ribs are provided along the circumferential direction of the mounting groove, the plurality of ribs dividing the mounting groove into several sub-grooves.

[0014] In some embodiments, the inductive coil is fixed to the groove by a second adhesive.

[0015] In some embodiments, the mounting base has a through hole extending through opposite sides of the mounting base;

[0016] The inductive loop module also includes a first fastener and a second fastener. The first fastener can be fixedly inserted into an external fixture, and a connection hole is provided at the end of the first fastener facing the mounting base.

[0017] The second fastener includes a head and a rod connected together. The head is located on the side of the mounting base opposite to the first fastener, and the rod can pass through the through hole and be fixedly connected to the connection hole.

[0018] In some embodiments, the inductive coil module further includes a washer fitted onto the rod portion and located between the first fastener and the mounting base, with one end of the washer abutting against the end face of the first fastener and the other end of the washer abutting against the mounting base.

[0019] Based on the same inventive concept, this utility model embodiment also provides a vehicle management system, including the inductive loop module described in any of the above embodiments.

[0020] Compared with existing technologies, the inductive loop module and vehicle management system provided in this embodiment of the invention, because the inductive loop is set in the wire groove of the mounting base, when it is necessary to install the inductive loop module on an external fixed object, it is only necessary to fix the mounting base on the external fixed object to complete the fixed installation of the inductive loop module on the external fixed object. The installation process of the inductive loop module is relatively simple, convenient and quick, saving labor installation costs and time costs. Moreover, compared with the traditional method of cutting wire grooves in the ground to install the inductive loop, this embodiment does not require cutting wire grooves in the ground, thus not damaging the integrity of the ground and reducing the cost of ground grooving.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0032] The following will be combined with the appendix Figures 1 to 6 The inductive loop module 100 and vehicle management system provided in this embodiment of the present invention will be described in detail.

[0033] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural diagram of the inductive loop module 100. Figure 2 This is a cross-sectional structural diagram of the inductive loop module 100 after it has been installed on the external fixture 200.

[0034] This utility model provides a ground inductor module 100, including a mounting base 10 and a ground inductor 20. The mounting base 10 can be fixedly engaged with an external fixing object 200. The mounting base 10 has a wire groove 11, and the ground inductor 20 is disposed in the wire groove 11.

[0035] The inductive loop module 100 can be a parking space in a parking lot, the entrance or exit of a toll station, a lane, or other places where vehicle detection is required. The external fixing object 200 can be the ground or a structural component for fixing the inductive loop module 100. For example, in some embodiments, the external fixing object 200 is the ground, and the inductive loop module 100 is directly installed on the ground. In other embodiments, the external fixing object 200 is a structural component that can be fixed to the ground, and the inductive loop module 100 is installed on the structural component. The external fixing object 200 typically has a relatively horizontal and relatively hard surface to facilitate the installation of the inductive loop module 100.

[0036] The inductive coil module 100 includes a mounting base 10 and an inductive coil 20. The mounting base 10 has a wire groove 11 adapted to the inductive coil 20. The inductive coil 20 is housed in the wire groove 11, so that the mounting base 10 and the inductive coil 20 can form a whole.

[0037] When it is necessary to install the inductive coil module 100 on the external fixture 200, simply fix the mounting base 10 onto the external fixture 200 to complete the installation of the inductive coil module 100 on the external fixture 200. The installation process of the inductive coil module 100 is simple, convenient, and quick, saving labor and time costs. Furthermore, compared to the traditional method of cutting grooves in the external fixture 200 to install the inductive coil 20, this embodiment does not require cutting grooves in the external fixture 200, thus not damaging the integrity of the external fixture 200 and reducing the cost of cutting grooves in the external fixture 200.

[0038] In some embodiments, after the inductive coil module 100 is installed, the side surface of the mounting base 10 facing the external fixture 200 fits seamlessly with the external fixture 200, ensuring the stability and reliability of the inductive coil module 100 after installation.

[0039] In some embodiments, the mounting base 10 may be configured as a generally ring-shaped structure, but is not limited thereto. For example, the mounting base 10 may also be configured as a generally rectangular structure.

[0040] In some embodiments, the mounting base 10 has a generally flat structure to ensure that the mounting base 10 protrudes less from the external fixation 200 to reduce interference to vehicles or pedestrians. Optionally, the central area of ​​the mounting base 10 is relatively thick and the edge area is relatively thin to facilitate a smooth transition between the external fixation 200 and the mounting base 10, thereby reducing the bumpy feeling when vehicles pass by.

[0041] In some embodiments, the inductive coil 20 is a ring coil structure formed by winding multiple coils, and the shape of the groove 11 is adapted to the shape formed by the inductive coil 20. For example, the inductive coil 20 can be a ring inductive coil, and correspondingly, the groove 11 can be a ring groove. Alternatively, the inductive coil 20 can be a rectangular inductive coil, and correspondingly, the groove 11 can be a rectangular groove.

[0042] In some embodiments, the mounting base 10 can be fixed to the external fixture 200 by fasteners such as screws and bolts.

[0043] Please see Figure 3 , Figure 3 yes Figure 1 The enlarged view at point A shows that in some embodiments, the mounting base 10 can be fixed to the external fixture 200 by adhesives such as glue.

[0044] In some embodiments, the mounting base 10 is further provided with a mounting groove 14 on the side facing the external fixture 200. The mounting groove 14 is filled with a first adhesive 140, and the mounting base 10 and the external fixture 200 can be fixedly connected by the first adhesive 140.

[0045] Optionally, the first adhesive 140 can be a structural adhesive or other special adhesive, such as anchoring adhesive, epoxy resin adhesive, polyurethane adhesive, etc. Structural adhesives usually have good bonding strength and long-term stability, which can ensure the stability and durability of the connection between the mounting base 10 and the external fixing object 200.

[0046] During installation, the first adhesive 140 can be filled into the mounting groove 14 first, and then the mounting base 10 can be placed on top of the external fixture 200 so that the first adhesive 140 in the mounting groove 14 is in full contact with the external fixture 200. After the first adhesive 140 is cured, the mounting base 10 and the external fixture 200 can be stably connected, and the installation of the inductive coil module 100 on the external fixture 200 can be completed.

[0047] In some embodiments, the mounting slot 14 may have only one.

[0048] In some embodiments, the mounting base 10 has a ring-shaped structure, and there are multiple mounting grooves 14 pointing from the center of the mounting base 10 to its edge. The multiple mounting grooves 14 are spaced apart, and the wire groove 11 is disposed between two adjacent mounting grooves 14.

[0049] Optionally, the mounting groove 14 can be configured as an annular groove or a rectangular groove, etc. Multiple mounting grooves 14 are provided, pointing from the center of the mounting base 10 to its edge. The multiple mounting grooves 14 are spaced apart. By filling each mounting groove 14 with a first adhesive 140, the bonding stability between the mounting base 10 and the external fastener 200 can be further increased.

[0050] The cable tray 11 is disposed between two adjacent mounting trays 14. In other words, at least one mounting tray 14 is located on the outer periphery of the cable tray 11. The cable tray 11 is bonded to the external fixing object 200 by the first adhesive 140 in the mounting tray 14, which can achieve the effect of waterproofing and dustproofing, and prevent water from soaking into the cable tray 11 and affecting its durability.

[0051] like Figure 3 As shown, in some embodiments, a first protrusion 141 is provided on the inner sidewall of the mounting groove 14, and a second protrusion 110 is provided on the inner sidewall of the wire groove 11.

[0052] A plurality of first protrusions 141 are provided at intervals on the two opposite inner sidewalls of the mounting groove 14. After the first adhesive 140 is filled into the mounting groove 14, the first protrusions 141 can increase the contact area between the first adhesive 140 and the inner wall of the mounting groove 14, increase the friction between the mounting groove 14 and the first adhesive 140, reduce the flow of the first adhesive 140 in the mounting groove 14, and make the first adhesive 140 adhere evenly to the inner wall of the mounting groove 14, so as to avoid the first adhesive 140 from forming cracks with the inner wall of the mounting groove 14 after curing, which would affect the bonding effect.

[0053] Several second protrusions 110 are provided at intervals on the two opposite inner sidewalls of the wire groove 11. After the second adhesive 21 is filled into the wire groove 11, the second protrusions 110 can increase the contact area between the second adhesive 21 and the inner wall of the mounting groove 14, increase the friction between the wire groove 11 and the second adhesive 21, reduce the flow of the second adhesive 21 in the wire groove 11, and make the second adhesive 21 adhere evenly to the inner wall of the wire groove 11, so as to avoid the second adhesive 21 from forming cracks with the inner wall of the wire groove 11 after curing, which would affect the bonding effect.

[0054] Optionally, the first protrusion 141 and the second protrusion 110 can both be trapezoidal protrusions, triangular protrusions, serrated protrusions, or rhomboid protrusions, etc.

[0055] In some embodiments, the first protrusion 141 is a trapezoidal protrusion, the top surface of which is connected to the inner wall of the mounting groove 14, and the bottom surface of which faces the center of the mounting groove 14.

[0056] like Figure 3 As shown, the area of ​​the top surface of the trapezoidal protrusion is smaller than the area of ​​the bottom surface of the trapezoidal protrusion. The trapezoidal protrusion can further increase the contact area between the first adhesive 140 and the inner wall of the mounting groove 14, increase the friction between the mounting groove 14 and the first adhesive 140, reduce the flow of the first adhesive 140 in the mounting groove 14, and make the first adhesive 140 more evenly distributed on the inner wall of the mounting groove 14. This avoids the first adhesive 140 from forming cracks with the inner wall of the mounting groove 14 after curing, and ensures the bonding effect between the mounting base 10 and the external fixing object 200.

[0057] In some embodiments, the second protrusion 110 is a trapezoidal protrusion, the top surface of which is connected to the inner wall of the mounting groove 14, and the bottom surface of which faces the center of the groove 11.

[0058] The area of ​​the top surface of the trapezoidal protrusion is smaller than the area of ​​the bottom surface of the trapezoidal protrusion. The trapezoidal protrusion can further increase the contact area between the second adhesive 21 and the inner wall of the wire groove 11, increase the friction between the wire groove 11 and the second adhesive 21, reduce the flow of the second adhesive 21 in the wire groove 11, make the second adhesive 21 more evenly distributed on the inner wall of the wire groove 11, avoid the second adhesive 21 from forming cracks with the inner wall of the wire groove 11 after curing, and ensure the bonding effect between the wire groove 11 and the external fixing object 200.

[0059] In some embodiments, the mounting base 10 further includes a rib 15 (see...) Figure 3 Multiple ribs 15 are provided along the circumferential direction of the mounting groove 14, and the multiple ribs 15 divide the mounting groove 14 into several sub-grooves.

[0060] like Figure 3 As shown, the rib 15 and the mounting base 10 can be integrally formed. On the one hand, the setting of the rib 15 increases the structural strength of the mounting base 10 and ensures the load-bearing performance of the mounting base 10. On the other hand, the rib 15 helps to block the flow of the first adhesive 140 along the circumferential direction of the mounting groove 14, further ensuring the uniform distribution of the first adhesive 140 in the mounting groove 14.

[0061] Please see Figure 4 , Figure 4 yes Figure 2 A partial enlarged view at point B. In some embodiments, the inductive coil 20 is fixed to the wire groove 11 by a second adhesive 21.

[0062] Optionally, the second adhesive 21 can be a fixing adhesive or other specialized adhesive, such as glass glue, waterproof glue, or hot melt adhesive. Fixing adhesives typically have a faster curing speed and can form adhesion in a short time, thereby reducing the production cycle of the inductive coil module 100.

[0063] In practice, the inductive coil 20 is first installed in the cable tray 11, and then the second adhesive 21 is injected. After the second adhesive 21 cures, the fixing effect is achieved. This fixing method is simple and low in cost. Moreover, the second adhesive 21 can provide good bonding strength, ensuring that the inductive coil 20 is stable and does not move in the cable tray 11, and preventing the inductive coil 20 from loosening or falling off during use.

[0064] It is understood that in other embodiments, the inductive coil 20 can also be fixed in the wire groove 11 in other ways, for example, the inductive coil 20 can be fixed in the wire groove 11 using mechanical structures such as clips or clamps.

[0065] Please see Figure 4 , Figure 5 and Figure 6 , Figure 5 This is a three-dimensional structural diagram of the mounting base 10. Figure 6 This is an exploded structural diagram of the inductive loop module 100.

[0066] In some embodiments, the mounting base 10 has a through hole 12 extending through opposite sides of the mounting base 10. The inductive coil module 100 also includes a first fastener 30 and a second fastener 40. The first fastener 30 can be fixedly inserted into the external fixing object 200, and the end of the first fastener 30 facing the mounting base 10 has a connection hole 31. The second fastener 40 includes a head 41 and a rod 42 connected to each other. The head 41 is located on the side of the mounting base 10 away from the first fastener 30, and the rod 42 can pass through the through hole 12 and be fixedly connected to the connection hole 31.

[0067] During installation, the first fastener 30 is first vertically inserted into the external fixture 200. Then, the mounting base 10 is placed on the external fixture 200, aligning the connecting hole 12 on the mounting base 10 with the connecting hole 31 on the first fastener 30. Finally, the rod 42 of the second fastener 40 is passed through the connecting hole 12 and screwed into the connecting hole 31 on the first fastener 30. Once the second fastener 40 is tightened, the inductive coil module 100 can be securely installed on the external fixture 200.

[0068] Optionally, the first fastener 30 can be a screw, the second fastener 40 can be a bolt, and the connecting hole 31 is a threaded hole. Multiple first fasteners 30 and second fasteners 40 can be configured respectively, which can more effectively distribute the force, reduce the pressure concentration phenomenon of a single fastener, and enhance the stability and durability of the overall connection.

[0069] In some embodiments, the outer surface of the mounting base 10 (the side surface facing away from the external fixing object 200) is provided with a countersunk hole 13, which is connected to the connecting hole 12. The head 41 of the first fastener 30 is disposed in the countersunk hole 13 to prevent the first fastener 30 from protruding from the outer surface of the mounting base 10.

[0070] In some embodiments, in order to facilitate the installation of the first fastener 30 on the external fixture 200, a mounting hole can be drilled in the external fixture 200 using a tool such as an electric drill, and then the first fastener 30 can be inserted into the mounting hole and fixed in the mounting hole using an adhesive such as glue.

[0071] In some embodiments, the inductive loop module 100 further includes a washer 50 (see...) Figure 4 The washer 50 is fitted onto the rod 42 and located between the first fastener 30 and the mounting base 10. One end of the washer 50 abuts against the end face of the first fastener 30, and the other end of the washer 50 abuts against the mounting base 10.

[0072] The washer 50 can be a hollow cylindrical structure and is located between the first fastener 30 and the mounting base 10. The washer 50 maintains a certain gap between the first fastener 30 and the mounting base 10, preventing glue from overflowing from the mounting hole and sticking to the mounting base 10 during assembly. Thus, when the inductive coil module 100 needs to be disassembled for maintenance, the inductive coil module 100 can be easily disassembled simply by unscrewing the first fastener 30. In other words, if the washer 50 is not provided, glue in the mounting hole may easily overflow and stick to the mounting base 10 during the tightening of the first fastener 30, thus affecting the disassembly and maintenance of the mounting base 10.

[0073] In some embodiments, the mounting base 10 can also be fixed to the external fixture 200 by welding or other methods. Furthermore, the mounting base 10 can be fixed to the external fixture 200 using a combination of methods to enhance connection stability and reliability. For example, the mounting base 10 can be fixed to the external fixture 200 using a combination of fasteners and adhesives. Fixing the mounting base 10 using a combination of methods can further increase the connection strength and reliability of the mounting base 10.

[0074] Based on the same inventive concept, this utility model embodiment also provides a vehicle management system, which includes the ground induction coil module 100 in any of the above embodiments, and therefore also has the beneficial effects of any of the above embodiments. For specific effects, please refer to the above text, which will not be repeated here.

[0075] In some embodiments, the vehicle management system further includes a parking lock and a controller. The controller is electrically connected to the ground induction coil 20 and the parking lock, respectively. The specific structures of the controller and the parking lock can be referred to the prior art, and will not be described in detail here.

[0076] When a parking space is empty, the inductive loop 20 does not detect a vehicle, and the parking lock is in the locked state (raised) to prevent other vehicles from occupying the space. When the inductive loop 20 detects a vehicle approaching the parking space, it senses a change in the magnetic field and sends a first sensing signal to the controller. Upon receiving the first sensing signal, the controller determines whether the vehicle is legitimate. If the vehicle is legitimate, it sends an unlock command to the parking lock. Upon receiving the unlock command, the parking lock lowers, allowing the vehicle to park safely. When the vehicle is about to leave the parking space, the inductive loop 20 detects another change in the magnetic field and sends a second sensing signal to the controller. Upon receiving the second sensing signal, the controller determines that the vehicle has left and sends a lock command to the parking lock. The parking lock rises again to return to the locked state, preventing other vehicles from occupying the parking space. In this way, by working together with the parking lock and the inductive loop module 100, automated parking space management can be achieved.

[0077] In some embodiments, the vehicle management system further includes a barrier gate and a controller, wherein the controller is electrically connected to the ground induction coil 20 and the barrier gate respectively. The specific structures of the controller and the barrier gate can be referred to the prior art, and will not be described in detail here.

[0078] When no vehicle approaches the barrier gate, the inductive loop 20 detects no vehicle, and the barrier gate remains closed (i.e., the barrier arm is down). When a vehicle approaches the barrier gate, the inductive loop 20 senses a change in the magnetic field and sends a third sensing signal to the control system. Upon receiving the third sensing signal, the controller determines whether to allow the vehicle to pass. If allowed, the controller sends an opening command to the barrier gate. Upon receiving the opening command, the barrier arm rises, allowing the vehicle to pass. Once the vehicle has completely passed through the barrier gate, the inductive loop 20 detects another change in the magnetic field and sends a fourth sensing signal to the controller. Upon receiving the fourth sensing signal, the controller determines that the vehicle has moved away and sends a closing command to the barrier gate. Upon receiving the closing command, the barrier arm falls, returning to the closed state. Thus, by using the inductive loop module 100 in conjunction with the barrier gate, automated vehicle access control can be achieved.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; under the concept of this utility model, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this utility model as described above. For the sake of brevity, they are not provided in detail; although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
