Description

Technical Field

[0001] The present invention relates to the technical field of school bags, in particular to an intelligent school bag with radio positioning. Background Art

[0002] The radio-positioning smart backpack is an innovative product that combines radio-positioning technology with the functions of traditional backpacks. It is designed to provide more safety and convenience for students and their parents. The backpack has a built-in GPS module and satellite positioning system, which determines the backpack's precise location by receiving satellite signals. The outdoor accuracy reaches 5CEP, and positioning can be achieved even in complex environments such as indoors, underground parking lots, tunnels, and urban areas with high-rise buildings.

[0003] Although existing smart backpacks with radio positioning are equipped with a positioning system, parents can determine the location of their students in real time based on the location of the backpack. However, when students are going to and from school, parents are most concerned about the safety of their students. When students encounter criminals during their commute and the backpack is separated from their body, parents cannot determine the specific situation of the students based on the location of the backpack, which will cause the students to lose this important positioning identifier. It is difficult for parents and schools to track the whereabouts of students, which increases the difficulty of finding students and makes it easier for criminals to hide the location of students, posing a threat to students' personal safety.

A V-shaped spring piece 309 is embedded in the internal movement of the spring lock 304, and the smart locking component 4, the spring smart locking component 4 includes a plurality of incomplete gears 401, and the outer surfaces of the plurality of spring incomplete gears 401 are all provided with rectangular card grooves 402. The outer surfaces of the plurality of spring incomplete gears 401 are all meshed and connected with the passive gear 404, and a threaded rod 409 is provided between the interiors of the plurality of spring incomplete gears 401. The spring protection component 3 also includes a protection box 301, and the spring protection box 301 is connected to the inner surface of the plurality of spring incomplete gears 401. The fixing belt is fixedly connected to the outer surface of one of the shoulder straps 2, and the relative inner walls of the spring protection box 301 are fixedly installed with limiting rods 315. A spring-type steel wire rope automatic reel 302 is set between one end of the two spring limiting rods 315. The interior of the spring-type steel wire rope automatic reel 302 is movably wound with a steel wire braided rope 303. One end of the spring steel wire braided rope 303 is fixedly connected to the outer surface of the lock buckle 304. The spring rotating tooth buckle 306 is set inside the lock buckle 304. The outer surface of the spring rotating tooth buckle 306 is meshed with the outer surface of the rotating rod 308, and the outer surface of the spring V-shaped spring piece 309 is in contact with the outer surface of the rotating rod 308. The outer surface of the spring lock buckle 304 is fixedly installed with a handle 310, and the outer surface of the spring rotating tooth buckle 306 is fixedly installed with a positioning block 311 for preventing one end of the rotating tooth buckle 306 from moving out of the inside of the lock buckle 304. The outer surface of the spring lock buckle 304 is fixedly installed with an inner tooth ring 312, and the inner part of the spring inner tooth ring 312 is engaged with a driving gear 313. The inner wall of the spring driving gear 313 is fixedly connected to the outer surface of the rotating shaft 305. The outer surfaces of the spring lock buckle 304 and the rotating tooth buckle 306 both slide with the inner wall of the protective box 301, and the outer surface of the other side of the spring rotating rod 308 is fixedly connected to a positioning rod 314 near one end.

[0035] In this embodiment, when a student is using a smart backpack with radio positioning, in order to prevent the GPS locator 5 in the backpack from being separated from the human body and posing a hidden danger to the student's safety, the student pulls out the handle 310 with one hand while carrying the backpack, thereby pulling the lock buckle 304 and the rotating tooth buckle 306 out of the interior of the protective box 301. Figure 3 As shown, the movement of the handle 310 drives the braided wire rope 303 to expand and contract outward, wherein the core component of the spring-type automatic wire rope retractor 302 is the clockwork spring, which works by utilizing the elastic energy storage characteristics of the clockwork spring. When the braided wire rope 303 is pulled out, the spring is twisted by force and stores energy. When the external force is removed, the spring releases energy to generate a rotational torque, which drives the reel to rotate, thereby realizing the automatic reeling of the wire rope 303. Then, one hand can be inserted into the Figure 4 The lock buckle 304 and the rotating tooth buckle 306 are shown in the closed ring, so that the ring is placed on the student's arm, and then the rotating shaft 305 can be rotated clockwise to drive the driving gear 313 to rotate. Since the inner protrusions in the inner gear ring 312 are made of rubber material with a certain elasticity, the protrusions in the inner gear ring 312 are deformed when squeezed by the driving gear 313, until the protrusions in the driving gear 313 rotate to between the protrusions in the other two adjacent inner gear rings 312, thereby limiting the driving gear 313 and preventing it from rotating without external force. The rotation of the rotating shaft 305 drives one end of the rotating tooth buckle 306 to rotate toward the inside of the first lock buckle 304, so that the inclined groove in the rotating tooth buckle 306 is limited by the tooth mouth in the rotating rod 308 and cannot be moved out from the inside of the first lock buckle 304 until the ring formed by the lock buckle 304 and the rotating tooth buckle 306 corresponds to the outer diameter of the student's arm, that is, the GPS locator 5 in the schoolbag is fixed in the student's arm, so that outsiders cannot separate the GPS locator 5 in the schoolbag body 1 from the student, so that parents can know the student's location in real time through the GPS locator 5, thereby enhancing the safety protection of the student.

[0036] like Figures 1-6 and Figures 8-10As shown, the spring intelligent locking component 4 also includes a fixed tube 403, and the two ends of the spring fixed tube 403 are respectively movable and penetrate the opposite outside of the protection box 301, and the inner walls of the multiple spring passive gears 404 are rotatably connected to the outer surface of the fixed tube 403, and the opposite inner walls of the multiple spring incomplete gears 401 are movably embedded with I-shaped connecting buckles 410. The outer surfaces of each adjacent two spring incomplete gears 401 are respectively rotatably connected through multiple I-shaped connecting buckles 410, and the outer surfaces of the incomplete gears 401 arranged at both ends are respectively rotatably connected to the relative inner walls of the protection box 301, and the outer surface of the spring protection box 301 is fixedly installed It is equipped with a protective cover 405, an intelligent controller 406 is set on the outer surface of the spring protective cover 405, a telescopic frame 407 is fixedly installed on the inner wall of the spring protective cover 405, both ends of the spring telescopic frame 407 are fixedly connected to the outer surface of the protective box 301, a forward and reverse motor 408 is set on the inner wall of the spring telescopic frame 407, the output end of the spring forward and reverse motor 408 is fixedly connected to one end of the threaded rod 409, the outer surface of the spring threaded rod 409 is sequentially connected to the internal threads of multiple incomplete gears 401, a GPS locator 5 is set on the outer surface of one side of the spring lock 304, and an alarm 6 is set on the outer surface of the other side of the spring lock 304.

[0037] In this embodiment, in order to further prevent the lock 304 and the rotating tooth buckle 306 from being maliciously opened, the student can click on the smart controller 406, wherein the smart controller 406 sends a control signal to the forward and reverse motor 408 actuator according to the algorithm analysis result. The forward and reverse motor 408 is connected to the GPS locator 5 of the backpack. After receiving the signal from the smart controller 406, the forward and reverse motor 408 adjusts its own speed, thereby driving the relevant components to run at an appropriate speed, realizing the automatic speed adjustment function. The smart controller 406 has a built-in NB-IoT module, which communicates with the mobile phone through the operator's base station network. Even if the child is in a relatively far away area or a complex signal area, as long as Within the coverage of the operator's network, the smart controller 406 can send key positioning information and the like to the cloud server associated with the mobile phone. The mobile phone obtains the status of the backpack by accessing the cloud, realizes remote connection and control, and starts the forward and reverse motor 408 through the smart controller 406 to drive the threaded rod 409 to rotate, thereby driving one of the incomplete gears 401 threadedly connected to the threaded portion on the surface of the threaded rod 409 to rotate, and drives the threaded rod 409 to move away from the protective sleeve 405. When the threaded portion of the threaded rod 409 is completely moved out of the interior of the incomplete gear 401, the rectangular slot 402 in the incomplete gear 401 is just completely rotated to the position away from the protective sleeve 405. The position of the positioning rod 314, wherein the inner diameters of the plurality of rectangular slots 402 are all larger than the outer diameter of the positioning rod 314, in order to limit the remaining incomplete gears 401 that are not connected to the threaded portion of the threaded rod 409, when one of the incomplete gears 401 rotates, it drives the corresponding passive gear 404 to rotate, and when the incomplete gear 401 is no longer connected to the threaded portion in the threaded rod 409, the friction limit of the passive gear 404 prevents the incomplete gear 401 from continuing to rotate. When the threaded rod 409 moves to the inside of one of the incomplete gears 401, the intelligent controller 406 can turn off the forward and reverse motor 408. When the outer When a person needs to pass through the circular ring formed by the lock buckle 304 and the rotating tooth buckle 306, it is difficult to rotate all the rectangular slots 402 to the position corresponding to the positioning rod 314 because the specific moving position of the threaded rod 409 is unknown, so that the inclined groove in the rotating tooth buckle 306 and the tooth mouth in the rotating rod 308 cannot be separated. Through the function of the protective component 3, when a student encounters an emergency, he can put the GPS locator 5 on the backpack on his arm in time to prevent the GPS locator 5 from being separated from the student, thereby solving the problem in the prior art that when a student encounters a safety problem, the radio positioning device is easily separated from the human body, posing a threat to the student's personal safety.

[0038] like Figures 1-10As shown, a smart schoolbag with radio positioning includes a schoolbag body 1 and two shoulder straps 2, wherein the outer surface of one of the shoulder straps 2 is provided with a protective component 3 for protecting the radio positioning device, and the interior of the protective component 3 is provided with a smart locking component 4 for preventing the radio positioning device from being separated from the student, the protective component 3, the protective component 3 includes a lock 304, a rotating shaft 305 is movably embedded between the opposite inner walls of the lock 304, and a rotating tooth buckle 306 is fixedly sleeved on the outer surface of the rotating shaft 305, and a fixed shaft 307 is fixedly installed between the opposite inner walls of the lock 304, and a rotating rod 308 is rotatably sleeved on the outer surface of the fixed shaft 307, and a plurality of inclined grooves are provided on the outer surface of one side of the rotating rod 308 near one end, and a V-shaped spring piece 309 is movably embedded in the interior of the lock 304, and a smart locking component 4 includes a plurality of incomplete gears 401, and the outer surfaces of the plurality of incomplete gears 401 are all provided with rectangular card slots 402, and the outer surfaces of the plurality of incomplete gears 401 are The surfaces are all meshed and connected with a passive gear 404, and a threaded rod 409 is set between the interiors of the multiple incomplete gears 401. The protection component 3 also includes a protection box 301, which is fixedly connected to the outer surface of one of the straps 2 through a fixing belt. The opposite inner walls of the protection box 301 are fixedly installed with a limit rod 315. A spring-type wire rope automatic reel 302 is set between one end of the two limit rods 315. The internal movement of the spring-type wire rope automatic reel 302 is wrapped with a wire. Braided rope 303, one end of the steel wire braided rope 303 is fixedly connected to the outer surface of the lock buckle 304, the outer surface of the lock buckle 304 is fixedly installed with an inner gear ring 312, the inner part of the inner gear ring 312 is meshed with a driving gear 313, the inner wall of the driving gear 313 is fixedly connected to the outer surface of the rotating shaft 305, the outer surfaces of the lock buckle 304 and the rotating gear buckle 306 both slide with the inner wall of the protective box 301, and the outer surface of the other side of the rotating rod 308 is fixedly connected to a positioning rod 314 near one end.

[0039] In this embodiment, when the student's parents need to remove the protective component 3, the parents can control the intelligent controller 406 through the mobile phone to start the forward and reverse motor 408, drive the threaded rod 409 to rotate, and then drive one of the incomplete gears 401 threadedly connected to the threaded part on the surface of the threaded rod 409 to rotate, thereby driving the threaded rod 409 to move toward the outside of the protective sleeve 405. At the same time, during the rotation of the incomplete gear 401, the corresponding rectangular slot 402 is driven to rotate. When the rectangular slot 402 rotates to the position corresponding to the positioning rod 314, the threaded part in the threaded rod 409 just moves out of the interior of the incomplete gear 401 and inserts into the interior of another incomplete gear 401, thereby rotating the other rectangular slot 402 to the position corresponding to the positioning rod 314. When the intelligent controller 406 controls all the incomplete gears 401 When the rectangular slots 402 are all rotated to the position corresponding to the positioning rod 314, the outer surface of the positioning rod 314 is no longer subject to the resistance of the incomplete gear 401, so that the elastic force of the V-shaped spring piece 309 drives the rotating rod 308 to rotate in the direction of the incomplete gear 401, thereby causing the positioning rod 314 to be inserted into the interior of the multiple rectangular slots 402, so that the outer surface of the rotating rod 308 is no longer in contact with the outer surface of the rotating tooth buckle 306. The student rotates the rotating shaft 305 in the opposite direction to drive one end of the rotating tooth buckle 306 to move outward from the interior of the lock buckle 304 until the outer surface of the positioning block 311 moves to a position that contacts the inner wall of the lock buckle 304. At this time, the inner diameter of the ring formed by the first lock buckle 304 and the rotating tooth buckle 306 is the largest. The student can move the ring out of the arm and then insert the ring into the interior of the protective box 301. Figure 3 As shown, two circular plates corresponding to the lock buckle 304 and the rotating tooth buckle 306 are set inside the protective box 301. The purpose is to limit the protective component 3. At the same time, when the lock buckle 304 is inserted into the protective box 301, the braided steel wire rope 303 is no longer pulled and can be retracted under the elastic force of the spring in the spring-type steel wire rope automatic reel 302, thereby realizing the positioning of the lock buckle 304 and the rotating tooth buckle 306.

[0040] like Figure 11As shown, it also includes a smart backpack system with radio positioning, which includes: a power management module 7, a wireless module 8, a radio frequency module 9, a baseband processing module 10, a storage module 11, an encryption module 12, an identity authentication module 13, an intrusion detection module 14, a security communication module 15, a security audit module 16 and a communication alarm module 17. The power management module 7 is used to provide a stable power supply to each module of the GPS locator 5 and manage and control the power supply. The wireless module 8 is used to receive satellite signals and convert the satellite signals into electrical signals and transmit them to the radio frequency module 9. The radio frequency module 9 is used to amplify, down-convert and other processes the radio frequency signals received by the wireless module 8 and convert them into intermediate frequency signals. The baseband processing module 10 is used to digitally process the intermediate frequency signals and calculate the three-dimensional coordinates of the receiver based on the distance information of multiple satellites. The storage module 11 is used to store the relevant data and programs of the radio positioning system, the encryption module 12 is used to encrypt the key data transmitted in the radio positioning system, the identity authentication module 13 is used to verify the legitimacy of the identity of users and devices. Only authorized users and devices can access the relevant data and functions of the radio positioning system. The intrusion detection module 14 is used to monitor the network traffic and system activities of the radio positioning system in real time, and promptly detect abnormal behavior and potential signs of hacker attacks. The secure communication module 15 is used to ensure the communication security between the radio positioning system and external devices. The security audit module 16 is used to record and audit all operations and activities of the radio positioning system to provide a basis for the investigation and handling of security incidents. The communication alarm module 17 is used to send out alarm information to the invaded radio positioning system.

[0041] In this embodiment, in order to prevent hackers from invading the smart backpack with wireless positioning and understanding the specific location of the student, first, the power management module 7 provides sufficient power to the wireless positioning device, and then the wireless module 8 receives satellite signals to ensure that the smart backpack can receive weak signals from multiple satellites and convert them into electrical signals for transmission to the radio frequency module 9. The radio frequency module 9 amplifies and down-converts the radio frequency signal received by the wireless module 8, converting it into an intermediate frequency signal for subsequent processing by the digital signal processing module. The baseband processing module 10 then digitizes the intermediate frequency signal and extracts the navigation message and pseudorange and carrier phase measurement information from it. In addition, the baseband processing module 10 is also responsible for time synchronization with the satellite, calculating the distance between the receiver and the satellite, and solving the three-dimensional coordinates of the receiver based on the distance information of multiple satellites to meet real-time and accuracy requirements. The storage module 11 is used to record historical positioning data for subsequent data analysis and trajectory playback, facilitating software upgrades and function expansion of the GPS locator 5 receiver. The encryption module 12 is mainly used to prevent the storage module 11 from being intruded by hackers to obtain the specific information of the student, and to protect the GPS locator 5. The location information and user identity information transmitted in the GPS locator are encrypted. By converting the original data into ciphertext for transmission and storage, it is ensured that even if the data is intercepted by hackers, it is difficult to decrypt and obtain the valid information therein. The identity authentication module 13 uses biometric authentication to identify the user's identity through fingerprint characteristics, which has high security and convenience. The intrusion detection module 14 is a rule-based intrusion detection system that matches network traffic and system behavior according to preset rules. When it finds behavior that meets the attack characteristics, it triggers the communication alarm module 17 to send an alarm message to the outside. The secure communication module 15 uses the transport layer security protocol to establish an encrypted connection between the communicating parties. This protocol can encrypt data and verify the identity of the other party through digital certificates to ensure the security and reliability of communication. The security audit module 16 sets up a special audit module in the system, which is responsible for recording various system events and operation information. The audit log is analyzed using log analysis tools to promptly detect abnormal behavior and security risks and send an alarm message to the outside through the communication alarm module 17. Through the multiple protections of the internal modules of the GPS locator 5, student information is effectively prevented from being leaked, further ensuring the safety of students.

[0042] The method of use and working principle of this device: When it is necessary to use a smart schoolbag with radio positioning, in order to prevent the GPS locator 5 in the schoolbag from being separated from the human body in case of a sudden situation and posing a hidden danger to the student's safety, the student pulls out the handle 310 with one hand while carrying the schoolbag, thereby pulling the lock buckle 304 and the rotating tooth buckle 306 out of the interior of the protective box 301, and then inserts one hand into the closed circular ring composed of the lock buckle 304 and the rotating tooth buckle 306, so that the circular ring is placed on the student's arm, and then the rotating shaft 305 can be rotated clockwise to drive the active gear 313 to rotate. Since the inner protrusions in the inner tooth ring 312 are made of rubber material with a certain elasticity, the protrusions in the inner tooth ring 312 are The driving gear 313 is squeezed and deformed until the protrusion in the driving gear 313 rotates to between the protrusions in the other two adjacent inner gear rings 312. As the rotating shaft 305 rotates, one end of the rotating tooth buckle 306 rotates toward the inside of the first lock buckle 304, so that the inclined groove in the rotating tooth buckle 306 is limited by the teeth of the rotating rod 308 and cannot be moved out of the inside of the first lock buckle 304 until the ring formed by the lock buckle 304 and the rotating tooth buckle 306 corresponds to the outer diameter of the student's arm, that is, the GPS locator 5 in the schoolbag is fixed in the student's arm, so that outsiders cannot separate the GPS locator 5 in the schoolbag body 1 from the student, so that parents can know the student's location in real time through the GPS locator 5. Then, the forward and reverse motors 408 are started by the intelligent controller 406 to drive the threaded rod 409 to rotate, thereby driving one of the incomplete gears 401 threadedly connected to the threaded portion on the surface of the threaded rod 409 to rotate, and driving the threaded rod 409 to move in the direction away from the protective sleeve 405. When the threaded portion of the threaded rod 409 is completely moved out of the interior of the incomplete gear 401, the rectangular slot 402 in the incomplete gear 401 is just completely rotated to a position away from the positioning rod 314. Among them, the inner diameters of the multiple rectangular slots 402 are all larger than the outer diameter of the positioning rod 314. In order to limit the remaining incomplete gears 401 that are not connected to the threaded portion in the threaded rod 409, when one of the incomplete gears 401 rotates, it drives the gear connected to it. When the incomplete gear 401 is no longer connected to the threaded portion of the threaded rod 409, the friction limit of the passive gear 404 prevents the incomplete gear 401 from continuing to rotate. When the threaded rod 409 moves to the inside of one of the incomplete gears 401, the intelligent controller 406 can turn off the forward and reverse motor 408. When an outsider needs to pass through the ring composed of the lock buckle 304 and the rotating tooth buckle 306, it is difficult to rotate all the rectangular slots 402 to the position corresponding to the positioning rod 314 because the specific moving position of the threaded rod 409 is unknown, so that the inclined groove in the rotating tooth buckle 306 cannot be separated from the tooth mouth in the rotating rod 308. When the student's parents need to remove the protective component 3,The parent can control the smart controller 406 through the mobile phone to start the forward and reverse motor 408, drive the threaded rod 409 to rotate, and then drive one of the incomplete gears 401 threadedly connected to the threaded portion on the surface of the threaded rod 409 to rotate, thereby driving the threaded rod 409 to move toward the outside of the protective sleeve 405. At the same time, during the rotation of the incomplete gear 401, the corresponding rectangular slot 402 is driven to rotate. When the rectangular slot 402 rotates to the position corresponding to the positioning rod 314, the threaded portion in the threaded rod 409 just moves out of the interior of the incomplete gear 401 and inserts into the interior of another incomplete gear 401, thereby rotating the other rectangular slot 402 to the position corresponding to the positioning rod 314. When the smart controller 4 When the rectangular slots 402 in all the incomplete gears 401 are rotated to the position corresponding to the positioning rod 314, the outer surface of the positioning rod 314 is no longer subject to the resistance of the incomplete gear 401, so that the rotating rod 308 is driven to rotate in the direction of the incomplete gear 401 under the elastic force of the V-shaped spring piece 309, thereby making the positioning rod 314 inserted into the interior of the plurality of rectangular slots 402, so that the outer surface of the rotating rod 308 is no longer in contact with the outer surface of the rotating tooth buckle 306. The student rotates the rotating shaft 305 in the opposite direction to drive one end of the rotating tooth buckle 306 to move outward from the inside of the lock buckle 304 until the outer surface of the positioning block 311 moves to the position in contact with the inner wall of the lock buckle 304. At this time, the first lock buckle 304 and the rotating The inner diameter of the ring formed by the tooth buckle 306 is the largest, and the student can move the ring out of the arm and then insert the ring into the interior of the protective box 301. At the same time, when the lock buckle 304 is inserted into the interior of the protective box 301, the braided steel rope 303 is no longer pulled and can be retracted under the elastic force of the spring in the spring-type steel wire rope automatic retractor 302, thereby realizing the positioning of the lock buckle 304 and the rotating tooth buckle 306. The power management module 7 provides sufficient power to the wireless positioning device, and then receives satellite signals through the wireless module 8 to ensure that the smart backpack can receive weak signals from multiple satellites and convert them into electrical signals for transmission to the radio frequency module 9. The radio frequency module 9 amplifies and downloads the radio frequency signals received by the wireless module 8. Frequency conversion processing, converting it into an intermediate frequency signal, the baseband processing module 10 then digitizes the intermediate frequency signal and extracts the navigation message and pseudorange, carrier phase measurement information from it. In addition, the baseband processing module 10 is also responsible for time synchronization with the satellite, calculating the distance between the receiver and the satellite, and solving the three-dimensional coordinates of the receiver based on the distance information of multiple satellites. The storage module 11 is used to record historical positioning data for subsequent data analysis and trajectory playback, which is convenient for software upgrades and function expansion of the GPS locator 5 receiver. The encryption module 12 encrypts the location information and user identity information transmitted in the GPS locator 5, and converts the original data into ciphertext for transmission and storage to ensure that even if the data is intercepted by hackers,It is also difficult to decrypt and obtain valid information. The identity authentication module 13 uses biometric authentication to identify the user's identity through fingerprint characteristics, which has high security and convenience. The intrusion detection module 14 is a rule-based intrusion detection system that matches network traffic and system behavior according to preset rules. When it finds behavior that meets the attack characteristics, it triggers the communication alarm module 17 to send an alarm message. The secure communication module 15 uses the transport layer security protocol to establish an encrypted connection between the communicating parties. This protocol can encrypt data and verify the identity of the other party through digital certificates. The security audit module 16 sets up a special audit module in the system, which is responsible for recording various system events and operation information. It uses log analysis tools to analyze the audit log, promptly discover abnormal behavior and security risks, and send an alarm message through the communication alarm module 17. Through the multiple protections of the internal modules in the GPS locator 5.
