Description

Technical Field

[0001] This invention relates to the fields of mechanical design and signal analysis technology, specifically to a self-powered vehicle condition monitoring system and detection method. Background Technology

[0002] In modern transportation systems, with the rapid development of intelligent vehicle technology, the demand for accurate monitoring of vehicle driving status is increasing. Vehicle driving status monitoring plays a crucial role in ensuring driving safety, optimizing vehicle performance, and improving energy efficiency. Currently, most vehicle driving status monitoring systems rely on multiple sensors, such as speed sensors, accelerometers, and gyroscopes, to collect data and determine the vehicle's driving status. These systems typically need to be connected to the vehicle's main power supply or powered by a separate battery, which not only increases the system's complexity but may also affect the vehicle's overall energy efficiency.

[0003] To address the aforementioned problems, this invention proposes a self-powered vehicle driving status monitoring system and detection method, aiming to reduce dependence on external power sources by using energy generated by the vehicle itself. Summary of the Invention

[0004] In view of this, the present invention provides a self-powered vehicle condition monitoring system and detection method to solve the problem that existing monitoring systems need to be connected to the vehicle's main power supply or use an independent battery for power, which not only increases the complexity of the system, but may also affect the overall energy efficiency of the vehicle.

[0005] The technical solution adopted in this invention is as follows:

[0006] A self-powered vehicle condition monitoring system, comprising:

[0007] A top cover and a bottom cover are connected to each other. The bottom of the top cover is provided with an annular platform, and the top of the bottom cover is rotatably connected to a rotor pendulum, which is located outside the annular platform.

[0008] An electromagnetic energy harvesting module includes several coils and magnets. The coils are spaced apart on the side wall of the annular truncated ring along the circumference of the ring, and the magnets are spaced apart on the rotor pendulum along the circumference of the rotor pendulum.

[0009] A triboelectric signal collection module includes a friction body and a friction plate. The friction body is disposed at the bottom of a rotor pendulum and can rotate with the rotor pendulum. The friction plate is disposed inside the bottom cover and is in contact with the friction body. The friction plate and the friction body generate electrical signals through mutual friction.

[0010] In this technical solution, it should be noted that the outer side of the bottom cover has bolt fixing seats, which can be fixed to the top cover by bolts. The inner side of the top cover has coil mounting positions and wire holes, arranged in a circle. The coils are installed in the coil mounting positions, and all the coils are connected in series through the wire holes. The magnet is a square magnet, installed in the magnet mounting position of the rotor pendulum. In specific use, this device is installed on a vehicle. When the vehicle is moving, the inertia and acceleration cause the rotor pendulum to swing back and forth, causing the magnet fixed on the rotor pendulum to swing back and forth. The coil fixed on the top cover generates an induced current due to the principle of electromagnetic induction. While the rotor pendulum is swinging, it drives the friction body to move. During the rotation of the friction body, friction occurs with the friction plate, thereby generating an electrical signal. The fluctuation characteristics of this electrical signal are essentially derived from the motion characteristics of the friction body, which are essentially transmitted by the rotor pendulum. The motion characteristics of the rotor pendulum originate from the motion characteristics of the vehicle, realizing the mapping of the vehicle's motion characteristics to the electrical signal. This electrical signal is sent to the terminal through the WIFI module or Bluetooth module of the integrated chip, and combined with the GRU deep learning algorithm to analyze and determine the vehicle's operating status.

[0011] Preferably, the rotor pendulum includes a rotating plate and a mounting plate. The rotating plate is rotatably connected to the bottom cover via a rotating shaft. The mounting plate is located on top of the rotating plate and is arranged along the circumference of the rotating plate.

[0012] In this technical solution, it should be noted that the magnet is set on the mounting plate, the bottom cover has a through hole in the center, the cylindrical roller bearing is installed in the through hole and is interference-fitted with the bottom cover, and the rotating shaft is rotatably connected to the bottom cover through the cylindrical roller bearing.

[0013] Preferably, the rotating plate has a fan-shaped structure.

[0014] In this technical solution, it should be noted that because the rotating plate has a fan-shaped structure, this design allows the rotating plate to rotate continuously through inertia, further improving power generation efficiency.

[0015] Preferably, the rotor pendulum has a tray at its bottom, the tray has a plurality of ball mounting holes, and the friction body includes PTFE balls, which are disposed in the friction holes;

[0016] The friction plate includes a copper ring band, which is disposed inside the bottom cover.

[0017] Preferably, the copper ring band includes a first ring band, a second ring band, a third ring band, and a fourth ring band arranged radially along the bottom cover. The first and second ring bands are located on the outer side and have a rectangular toothed interval. The first and second ring bands are symmetrically and staggered. The third and fourth ring bands are located on the inner side and have a rectangular toothed interval. The third and fourth ring bands are symmetrically and staggered.

[0018] Preferably, it also includes a signal collection and transmission module, which includes an integrated circuit board, a circuit board box, and a circuit board cover. The circuit board box is circular and fixed on the top cover. The integrated circuit board has electrical signal processing functions and integrates WIFI and Bluetooth modules to transmit signals to the terminal through the WIFI and Bluetooth modules.

[0019] Preferably, the integrated circuit board has a rectifier circuit, which can rectify the current collected by the electromagnetic energy harvesting module and directly drive the circuits in the integrated circuit board to work.

[0020] A self-powered vehicle condition detection method includes the following steps:

[0021] Step 1: Install a self-powered vehicle condition monitoring system at any location on the vehicle;

[0022] Step 2: The vehicle's movement drives the self-powered vehicle status monitoring system to work. The energy collected by the electromagnetic energy harvesting module powers the integrated circuit board, and the triboelectric signal harvesting module generates an electrical signal and transmits the corresponding characteristic electrical signal to the remote terminal.

[0023] Step 3: The remote terminal uses the GRU deep learning algorithm to analyze and determine the vehicle's driving status.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, a rotor pendulum is used to receive inertial kinetic energy, effectively transmitting vibration characteristics. Its application scenarios are not limited to the transportation field, but can also be extended to mechanical vibration monitoring and wave energy collection and monitoring, etc.

[0026] 2. The present invention is packaged into a cylinder, making full use of the space structure, with a compact structure. A single device can serve as a wireless Internet of Things node, and can then be extended to a multi-node wireless sensor network, with strong scalability.

[0027] 3. This invention adopts the principles of triboelectric power generation and electromagnetic induction power generation. The PTFE ball of the rotor pendulum and the two copper ring belts constitute the TENG. While generating electrical energy to provide power, it is highly sensitive to changes in characteristics, has stable operation, high reliability, and can effectively record the vibration characteristics of the environment.

[0040] Example 1

[0041] like Figures 1-4 As shown in the figure, an embodiment of the present invention discloses a self-powered vehicle status monitoring system, comprising:

[0042] A top cover 1 and a bottom cover 2 are connected to each other. The bottom of the top cover 1 is provided with an annular platform 13. The top of the bottom cover 2 is rotatably connected to a rotor pendulum 9, which is located outside the annular platform 13.

[0043] An electromagnetic energy harvesting module includes several coils 7 and magnets 8. The coils 7 are spaced apart on the side wall of the annular platform 13 along the circumference of the platform, and the magnets 8 are spaced apart on the rotor pendulum 9 along the circumference of the pendulum 9.

[0044] A triboelectric signal collection module includes a friction body 11 and a friction plate 12. The friction body 11 is located at the bottom of the rotor pendulum 9 and rotates with it. The friction plate 12 is located inside the bottom cover 2 and contacts the friction body 11. The friction plate 12 and the friction body 11 generate an electrical signal through mutual friction. It should be noted that the bottom cover 2 has a bolt fixing seat on its outer side, which can be fixed to the top cover 1 by bolts. The top cover 1 has coil 7 mounting positions and wire holes arranged in a circle on its inner side. The coils 7 are installed in the coil 7 mounting positions, and all the coils 7 are connected in series through the wire holes. The magnet 8 is a square magnet 8 and is installed in the magnet 8 mounting position of the rotor pendulum 9. In this solution, the device is installed on a vehicle. When the vehicle is moving, the inertia and acceleration cause the rotor pendulum 9 to oscillate back and forth, which in turn causes the magnet 8 fixed on the rotor pendulum 9 to oscillate back and forth. The coil 7 fixed on the top cover 1 generates an induced current due to electromagnetic induction. Simultaneously, the rotor pendulum 9 moves the friction body 11. During its rotation, the friction body 11 rubs against the friction plate 12, generating an electrical signal. The fluctuation characteristics of this electrical signal essentially originate from the motion characteristics of the friction body 11, which are essentially transmitted from the rotor pendulum 9. The motion characteristics of the rotor pendulum 9 originate from the motion characteristics of the vehicle, thus mapping the vehicle's motion characteristics to the electrical signal. This electrical signal is sent to the terminal via the integrated chip's WIFI or Bluetooth module, and combined with the GRU deep learning algorithm to analyze and determine the vehicle's operating status.

[0045] like Figures 2-4 As shown, in this embodiment, the rotor pendulum 9 includes a rotating plate 93 and a mounting plate 92. The rotating plate 93 is rotatably connected to the bottom cover 2 via a rotating shaft 93. The mounting plate 92 is located on the top of the rotating plate 93 and is arranged along the circumference of the rotating plate 93.

[0046] It should be noted that the magnet 8 is mounted on the mounting plate 92, the bottom cover 2 has a through hole in the center, the cylindrical roller bearing 6 is installed in the through hole and is interference-fitted with the bottom cover 2, and the rotating shaft 93 is rotatably connected to the bottom cover 2 through the cylindrical roller bearing 6.

[0047] like Figure 2 As shown, in this embodiment, the rotating plate 93 has a fan-shaped structure. It should be noted that because the rotating plate 93 has a fan-shaped structure, this design allows it to rotate continuously due to inertia, further improving power generation efficiency.

[0048] like Figure 2As shown, in this embodiment, the rotor pendulum 9 has a tray 10 at its bottom, and the tray 10 has a plurality of ball mounting holes 111. The friction body 11 includes PTFE balls, which are disposed in the friction holes. The friction plate 12 includes a copper ring belt, which is disposed in the bottom cover 2.

[0049] like Figure 3 As shown, in this embodiment, the copper ring band includes a first ring band 121, a second ring band 122, a third ring band 123, and a fourth ring band 124 arranged radially along the bottom cover 2. The first ring band 121 and the second ring band 122 are located on the outer side and have a rectangular toothed interval. The first ring band 121 and the second ring band 122 are symmetrically and staggered. The third ring band 123 and the fourth ring band 124 are located on the inner side and have a rectangular toothed interval. The third ring band 123 and the fourth ring band 124 are symmetrically and staggered.

[0050] like Figure 1 As shown, in this embodiment, a signal collection and transmission module is also included. The signal collection and transmission module includes an integrated circuit board 4, a circuit board box 3, and a circuit board cover 5. The circuit board box 3 is circular and fixed on the top cover 1. The integrated circuit board 4 has electrical signal processing functions and integrates WIFI and Bluetooth modules to transmit signals to the terminal through the WIFI and Bluetooth modules.

[0051] In this embodiment, the integrated circuit board 4 has a rectifier circuit, which can rectify the current collected by the electromagnetic energy harvesting module and directly drive the circuits in the integrated circuit board 4 to work.

[0052] Example 2

[0053] This embodiment proposes a self-powered vehicle status detection method, including the following steps:

[0054] Step 1: Install a self-powered vehicle condition monitoring system at any location on the vehicle;

[0055] Step 2: The vehicle's movement drives the self-powered vehicle status monitoring system to work. The energy collected by the electromagnetic energy harvesting module powers the integrated circuit board 4. The triboelectric signal harvesting module generates an electrical signal and transmits the corresponding characteristic electrical signal to the remote terminal.

[0056] Step 3: The remote terminal uses the GRU deep learning algorithm to analyze and determine the vehicle's driving status.

[0057] The principle of this invention is as follows:

[0058] When this device is installed on a vehicle, the vehicle's inertia and acceleration cause the rotor pendulum 9 to reciprocate, which in turn causes the magnet 8 fixed to the rotor pendulum 9 to reciprocate. The coil 7 fixed to the top cover 1 generates an induced current due to electromagnetic induction. Simultaneously, the rotor pendulum 9 moves the PTFE ball tray 10, which is fixedly connected to it. The PTFE balls are placed in the PTFE ball mounting holes 111 of the PTFE ball tray 10. Therefore, the PTFE balls are pushed by the PTFE ball tray 10, causing them to roll while simultaneously rotating as a whole. During rotation, the PTFE balls alternately contact the interlaced first and second ring belts 121 and 122, and the third and fourth ring belts 123 and 124. Due to the principle of triboelectric generation, a potential difference is generated between the interlaced first and second ring belts 121 and 122, and between the third and fourth ring belts 123 and 124, thus generating an alternating current signal. The fluctuation characteristics of this electrical signal essentially originate from the motion characteristics of the PTFE ball, which in turn are transmitted from the rotor pendulum 9. The motion characteristics of the rotor pendulum 9, in turn, originate from the vehicle's motion characteristics, thus mapping the vehicle's motion characteristics to the electrical signal. This electrical signal is transmitted to the terminal via the integrated chip's WIFI or Bluetooth module, and then analyzed and determined using the GRU deep learning algorithm.

[0059] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The scope of protection of this invention does not involve any improvement to the software and methods.

[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
