Description

Technical Field

[0001] This utility model relates to the field of smart campus assistant technology, specifically a smart campus assistant with intelligent interactive functions. Background Technology

[0002] With the promotion of smart campuses, more and more schools are deploying self-service information terminals, intelligent robots, and other interactive devices to complete student identity authentication, information inquiry, and daily affairs processing. Common operating methods include swiping ID cards, campus cards, and facial recognition. Through these devices, students and faculty can more conveniently complete tasks such as access control, attendance registration, and library borrowing, thereby improving the level of campus informatization.

[0003] However, a common problem in actual use is that students or faculty often forget to take their ID cards or campus cards after swiping their cards or having them recognized. If these documents are left on the device panel for an extended period, they are not only easily taken or lost by others, but also pose a security risk. Most existing self-service terminals have fixed panel structures, making them highly susceptible to damage or loss if the documents slip to the ground. While the devices have voice announcement functions, they cannot be linked to lost item detection, limiting their effectiveness in preventing such forgetting.

[0004] Therefore, a smart campus assistant with intelligent interactive functions is needed to address the aforementioned technical shortcomings. Utility Model Content

[0005] The purpose of this utility model is to provide a smart campus assistant with intelligent interactive functions, so as to solve the problem mentioned in the background art that although the device has voice broadcast function, it cannot be linked with the detection of lost items, and the reminder function is limited.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a smart campus assistant with intelligent interactive functions, including a lifting seat and a base. The lifting seat is movably connected inside the base, and a turntable is rotatably connected to the top of the lifting seat. A robot is fixedly connected to the top of the turntable. A camera is installed on the top of the front wall of the robot. Below the camera are indicator lights, a touch screen, a button area, a voice input module, a voice output module, and an ID card IC recognition module. A storage slot is opened on the front wall of the robot. A moving motor is fixedly installed at the bottom inside the robot. A ball screw is fixedly connected to the output shaft of the moving motor.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6 This utility model provides an embodiment of a smart campus assistant with intelligent interactive functions, including a lifting seat 12 and a base 20. The lifting seat 12 is movably connected inside the base 20. A turntable 13 is rotatably connected to the top of the lifting seat 12. A robot 1 is fixedly connected to the top of the turntable 13. A camera 2 is installed on the top of the front wall of the robot 1. Below the camera 2 are an indicator light 3, a touch screen 4, a button area 6, a voice input module 7, a voice output module 10, and an ID card IC recognition module 11. A storage slot 8 is provided on the front wall of the robot 1. A moving motor 26, model YS561-4, is fixed to the bottom of the robot 1. A ball screw 27 is fixedly connected to the output shaft of the moving motor 26. A screw sleeve 28 is sleeved on the outside of the ball screw 27. A storage plate 9 is fixedly connected to the top of the screw sleeve 28. The storage plate 9 is embedded in the storage groove 8 and moves. An infrared detector 29 is set on the left side of the surface of the storage plate 9, and an infrared receiver 30 is set on the right side of the surface of the storage plate 9. The thickness of the storage plate 9 matches the storage groove 8. The two sides of the storage plate 9 are embedded in the inner sidewall of the storage groove 8 and move.

[0027] Specifically, such as Figure 1 and Figure 2 As shown, robot 1 is fixed in a certain place. When a student or faculty member approaches, the moving motor 26 drives the ball screw 27 to rotate, and the screw sleeve 28 moves up and down accordingly, thereby pushing the shelf 9 outward along the shelf slot 8 to form a temporary storage area. At this time, students can place books, umbrellas or other small items on the shelf 9 to free their hands for operation. When swiping the ID card IC recognition module 11, if the student forgets to take the ID card, the ID card will automatically fall onto the shelf 9. After the infrared detector 29 on the left side of the shelf 9 detects the foreign object, it will interrupt the signal of the infrared receiver 30. Robot 1 will then remind the user to retrieve the item in time through the voice output module 10 to avoid students losing their ID cards or items due to forgetfulness. Through this intelligent interactive process, the risk of students losing their items on campus can be effectively reduced, and the level of intelligence and humanization of campus management can be improved.

[0028] A fixed plate 18 is fixedly connected inside the lifting seat 12. An electrical control box 24 is installed on one side of the bottom end of the fixed plate 18. A rotating column 15 is rotatably connected to the middle of the top of the fixed plate 18. A large gear 14 is fixedly sleeved on the outside of the rotating column 15. The top of the rotating column 15 passes through the lifting seat 12 and is fixedly connected to the bottom of the turntable 13. A steering motor 16 is fixedly connected to the right side of the top of the fixed plate 18. The steering motor 16 is model YS631-4. A small gear 17 is fixedly connected to the output shaft of the steering motor 16. The small gear 17 meshes with the large gear 14.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, a camera 2 is installed on the top front of robot 1. Below it, an indicator light 3, a touch screen 4, a button area 6, a voice input module 7, a voice output module 10, and an ID card IC recognition module 11 are arranged in sequence. When a student enters the campus, robot 1 will first perform facial recognition through camera 2. If the recognition angle does not match, the steering motor 16 can drive the small gear 17 to rotate, so that it meshes with the large gear 14, thereby driving the rotating column 15 to rotate, and then the turntable 13 drives the main body of robot 1 to rotate so that camera 2 is aligned with the student's face. Through this steering function, even if the student is in a wheelchair or is not in a direct facing position, camera 2 can quickly adjust the recognition angle to ensure that identity recognition is completed smoothly. This design can greatly improve the convenience and universality of facial recognition, and is particularly suitable for the diverse needs of different groups in a smart campus environment.

[0030] A cylinder 22 is fixed at the middle of the bottom end of the fixed plate 18. The cylinder 22 is model MGPM16-50Z. The bottom end of the piston rod of the cylinder 22 is fixedly connected to the bottom rod 23. The bottom rod 23 is fixed inside the base 20. Guide rods 21 are vertically fixed on both sides inside the base 20. A sliding sleeve 19 is sleeved on the outside of the guide rod 21. The sliding sleeve 19 is fixedly connected to the fixed plate 18. There are two sets of guide rods 21. The two sets of guide rods 21 are parallel and symmetrically arranged on both sides of the outside of the lifting seat 12.

[0031] Specifically, such as Figure 1 and Figure 5As shown, the lifting seat 12 is installed inside the base 20. When the user issues a "raise" or "lower" command through the voice input module 7, the cylinder 22 is activated and pushes the base rod 23 to extend or retract, thereby driving the lifting seat 12 to move up and down as a whole. The robot 1 is fixed on the top of the lifting seat 12. With the lifting action, the overall height of the robot 1 changes. This action allows the camera 2 to be adjusted to a position that matches students of different heights, ensuring the accuracy of facial recognition. During the lifting process, the guide rod 21 is arranged in two symmetrical sets, and the sliding sleeve 19 is sleeved on the guide rod 21 and connected to the fixing plate 18 to ensure the stability and anti-tilt of the lifting action and avoid shaking. Through this lifting function, students of all heights, including tall and short students and students with disabilities in wheelchairs, can complete recognition and interactive operations at the optimal height, enhancing the friendliness and accessibility of the smart campus environment.

[0032] Furthermore, the output end of cylinder 22 is connected to telescopic rod 13. Cylinder 22 includes cylinder barrel, piston, end cover, seal, solenoid valve, air source and air passage. Cylinder 22 is a fully disclosed prior art. The air source supply method is implemented in a conventional way, so it will not be described in detail.

[0033] The bottom of the base 20 is equipped with a base wheel 25. Two sets of guide sleeves 31 are fixedly connected to both sides of the robot 1. A hanging rod 5 is movably connected inside the guide sleeve 31. The hanging rod 5 has an inverted "L" shaped structure.

[0034] Specifically, such as Figure 1 , Figure 4 and Figure 6 As shown, guide sleeves 31 are fixedly connected to both sides of robot 1. A hanging rod 5 is movably connected inside the guide sleeve 31. The hanging rod 5 has an inverted "L" shape and can be pulled outward along the guide sleeve 31. When students enter the library, study room or laboratory, they can hang their bags, umbrellas, water bottles and other personal items on the hanging rod 5 to avoid placing items randomly on the ground or table, causing a cluttered environment. When not in use, the hanging rod 5 can be pushed back into the guide sleeve 31 for storage, without taking up space. This structure enables robot 1 to not only have identity recognition and interaction functions, but also to play an auxiliary storage role, providing a more convenient user experience for public areas on campus and improving the comprehensive service capabilities of smart campus equipment.

[0035] Furthermore, the electrical control box 24 uses a PLC as the controller, model S7-200 SMART ST20. The moving motor 26, steering motor 16, cylinder 22, camera 2, indicator light 3, touch screen 4, button area 6, voice input module 7, voice output module 10, ID card IC recognition module 11, infrared detector 29, and infrared receiver 30 are all electrically connected to the electrical control box 24. The electrical connection relationship and control method between them are existing technologies and will not be described in detail.

[0036] Working principle: During use, the lifting seat 12 inside the base 20 can be raised and lowered with the cooperation of cylinder 22 and guide rod 21, driving the overall height adjustment of robot 1 so that camera 2 can be aimed at the face of students of different heights, ensuring recognition accuracy. When a student approaches, the moving motor 26 drives the ball screw 27 to rotate, and the screw sleeve 28 pushes the shelf 9 out along the shelf groove 8, where students can temporarily place items or catch fallen documents. Infrared detector 29 and infrared receiver 30 are positioned to detect each other. When the detection signal is blocked, robot 1 will respond through the voice output module. 10 provides reminders to prevent items from being lost. During facial recognition, if the angle of camera 2 is not matched, the steering motor 16 drives the small gear 17 to rotate, meshing with the large gear 14 to drive the rotating column 15 to rotate, which in turn drives the turntable 13 to adjust its direction, so that camera 2 can quickly align with the student's face, ensuring that the recognition is completed smoothly. The guide sleeves 31 set on both sides of the robot 1 are movably connected to the hanging rods 5. The hanging rods 5 can be pulled out to form a temporary hanging area for students to hang their schoolbags or water bottles and other items. When not in use, they can be pushed back into the guide sleeves 31 for storage, improving the convenience of use and space utilization.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
