[0037] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] Please refer to Figures 1 to 3 A smart school badge sensor includes a housing 10 and an antenna reflector 20. The antenna reflector 20 includes an antenna reflective surface 21 and side edges 22 disposed around the antenna reflective surface 21 and folded inward.

[0039] Two antenna elements 23 are provided on the antenna reflector 21, and an antenna power divider 24 is provided between the two antenna elements 23;

[0040] The antenna power divider 24 connects two antenna elements 23 to form an RFID antenna array, and the input terminal of the antenna power divider 24 is connected to the signal line 25.

[0041] The side 22 is provided with a first wiring groove 27 for guiding the RFID antenna 26.

[0042] The back of the housing 10 is provided with a receiving cavity 11 that matches the shape of the antenna array 23 for accommodating the antenna array 23; the back of the housing 10 is provided with a potting groove 12 that matches the shape of the side 22, and after potting, a sealing layer is formed to fix the housing 10 and the antenna reflector 20.

[0043] Both sides of the glue potting tank 12 are provided with wiring grooves 13 for accommodating the RFID antenna 26, and the side wall of the glue potting tank 12 is also provided with a second wiring groove 14 for guiding the RFID antenna 26.

[0044] Preferably, the first wiring groove 27 and the second wiring groove 14 are grooves or round holes.

[0045] This invention improves the overall aesthetics and durability of the smart school badge sensor by integrating the antenna reflector 20 with the housing 10. The inward folding of the side 22 of the antenna reflector 21 not only increases structural stability but also guides the RFID antenna 26 through the design of the first wiring groove 27 and the second wiring groove 14, ensuring neat cable arrangement, avoiding exposure, and reducing the risk of damage. Furthermore, the accommodating cavity 11 and the potting groove 12 on the back of the housing 10 are designed to precisely accommodate the antenna array 23 and the side 22. The potting assembly enhances the structure's waterproof and dustproof performance, thereby improving the device's durability.

[0046] Preferably, the outer shell 10 is curved, similar to the structure of existing speed bumps, which enhances the aesthetics of the smart school badge sensor, allowing the device to better integrate into the campus environment and reduce visual obtrusion. Typically, speed bumps are installed at school entrances. Because the outer structure of this invention is similar to a speed bump, it can directly replace the existing speed bumps at school entrances and be installed on the road surface, resulting in a more aesthetically pleasing design without damaging other existing school buildings.

[0047] In this embodiment, the surface of the outer casing 10 is provided with a plurality of drainage grooves 15 for guiding rainwater or other liquids to avoid water accumulation.

Furthermore, multiple flow guide troughs 15 are evenly distributed at intervals to improve the flow guiding effect.

[0049] The guide groove 15 on the surface of the outer shell 10 of this utility model effectively solves the problem of possible water accumulation. Through the height difference of the guide groove 15, the water is guided to flow smoothly out, preventing water accumulation from damaging the equipment.

[0050] In this embodiment, the surface of the outer casing 10 is further provided with first mounting holes 16 for use with fasteners to install the smart school badge sensor. Preferably, there are four first mounting holes 16, located at the four corners of the outer casing 10, and the fasteners are expansion bolts.

[0051] In this embodiment, the back of the housing 10 is also provided with multiple support grooves 17 in a honeycomb structure. This not only improves the structural strength of the housing 10, but also maintains the overall lightweight structure and prevents signal attenuation. At the same time, it facilitates installation and maintenance.

[0052] Preferably, the thickness of the common sidewall of two adjacent support grooves 17 is 3.5 mm to ensure support. This invention, through precise dimensional control of the thickness of the common sidewall of adjacent support grooves 17, helps to improve the structural strength and durability of the entire intelligent school badge sensor.

[0053] In this embodiment, the outer shell 10 is made of PE material so that it can withstand the crushing of passing vehicles without being damaged.

[0054] In this embodiment, multiple reinforcing ribs 18 are provided on the side wall of the wiring channel 13 to enhance the structural strength of the wiring channel 13, prevent deformation or damage during use, thereby protecting the internal RFID antenna 26 and improving the reliability and durability of the entire smart school badge sensor.

[0055] Preferably, the wiring trough 13 is generally elongated, with multiple support grooves 17 in the lower half along the longitudinal direction, and the upper half includes a sidewall with a horizontal height higher than the horizontal height of the support grooves 17. In this embodiment, the glue-filling trough 12 is a rectangular trough, with multiple support grooves 17 in the lower half, and a sidewall with a horizontal height higher than the horizontal height of the support grooves 17 in the upper half.

[0056] In this embodiment, the antenna array 23 is provided with a hollow portion 23a to improve signal transmission efficiency. Preferably, the antenna array 23 is circular, the lower half of the accommodating cavity 11 is provided with a plurality of honeycomb-shaped support grooves 17, and the upper half includes sidewalls with a horizontal height higher than the horizontal height of the support grooves 17 and evenly spaced.

[0057] Furthermore, the support grooves 17 are all groove-shaped structures with a closed bottom, an open top, and a hollow center.

[0058] In this embodiment, an antenna fixing structure is also provided between the two antenna arrays 23; the antenna fixing structure includes a fixing piece 28, a second mounting hole (not shown in the figure), and a first fixing member 29; the second mounting hole is provided at both ends of the fixing piece 28, and the first fixing member 29 is used to cooperate with the second mounting hole to fix the RFID antenna 26. Preferably, the first fixing member 29 is a screw.

[0059] This invention provides a stable way to fix the RFID antenna 26 by setting an antenna fixing structure between the two antenna elements 23; it ensures the positional stability of the RFID antenna 26 and prevents the RFID antenna 26 from being broken.

[0060] The working principle of this invention is as follows: When a student wearing an RFID smart school badge enters the effective working range of the smart school badge sensor (this range depends on factors such as the sensor's power and the type of tag), the smart school badge sensor actively emits a radio frequency signal at a certain frequency. The RFID tag antenna in the school badge receives the radio frequency signal and is activated by the signal's energy. The identity information in the tag chip is modulated and loaded onto the returned radio frequency signal. After receiving this signal loaded with information, the smart school badge sensor processes the signal through its internal signal processing circuit, extracts the student's identity information, and then transmits it to the school's management system. The management system performs corresponding operations based on the received information, such as marking the student's arrival in the attendance system or recording the time the student passed through a specific area in the campus security system.

[0061] Several points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
