[0033] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0036] Example 1, referring to Figure 1 This is the first embodiment of the present invention. This embodiment provides a vibration monitoring module, including a monitoring component 100, including a sensing element 101. The sensing element 101 includes a vibration sensor 101a. The vibration sensor 101a monitors the parameters generated by the vibration of the reactor and transmits them to the signal management unit 104b of the control component 104 through the terminal 101b.

[0037] The control unit 104 also includes a power management unit 104a and a backup power supply unit 104c. The power management unit 104a supplies power from the solar panel 103a or the backup power supply unit 104c to the vibration sensor 101a.

[0038] The signal management unit 104b transmits the parameters generated by the reactor vibration to the receiving terminal.

[0039] Preferably, the sensing element 101 is fixedly disposed on the surface of the reactor for monitoring the vibration of the reactor; the sensing element 101 is used to sense the mechanical vibration and electromagnetic force vibration generated by the reactor during operation. This sensor can monitor the acceleration, frequency, and displacement of the vibration in real time and generate corresponding signal data.

[0040] Preferably, the power management unit 104a is used for the charging and discharging process of the backup power supply unit 104c. This unit can monitor the battery's state of charge and automatically stop charging when the backup power supply unit 104c is fully charged to prevent overcharging and thus extend battery life. This unit also supports a low battery alarm function to ensure that the device can still operate normally when the battery is low.

[0041] Furthermore, the signal management unit 104b is responsible for receiving and processing the vibration signals from the vibration sensor 101a. The processed data is transmitted wirelessly to the terminal device or monitoring center, supporting real-time monitoring and remote data analysis.

[0042] In this embodiment, the power supply component 103 mainly converts external solar energy into electrical energy to provide sufficient power to the sensor 101. By connecting to an external power source, the sensor 101 is powered to prevent problems from occurring in the reactor during operation, which could lead to the failure of this vibration monitoring module, i.e., the monitoring component 100.

[0043] In summary, by fixing the sensor 101 to the surface of the reactor, the vibration of the reactor is monitored. When the vibration amplitude of the reactor is too large, the staff can obtain information in time and deal with the reactor.

[0044] Example 2, refer to Figures 1-4 This is the second embodiment of the present invention. This embodiment provides a vibration monitoring device, including a housing 102 and a power supply 103.

[0047] Preferably, one end of the terminal 101b is electrically connected to the vibration sensor 101a. In this embodiment, the terminal 101b is mainly a conductive cable. The other end of the terminal 101b is connected to the signal management unit 104b, which transmits the monitored vibration data to the receiving end for processing via wired connection.

[0048] The vibration sensor 101a is directly adhered to a key part of the reactor body using an adhesive method. This adhesive method ensures close contact between the sensor and the reactor surface, thereby improving the sensitivity and accuracy of vibration detection.

[0049] In this embodiment, the housing 102 serves as a carrier for the control unit 104, which includes multiple control units, such as processing signals from the sensing unit 101 and supplying power to the sensing unit 101.

[0050] Preferably, the end face of the support plate 102c is provided with a plurality of heat dissipation holes that penetrate the entire support plate 102c, for heat dissipation of multiple units inside the housing 102a.

[0051] Furthermore, the cover 102b is hinged inside the housing 102a, facilitating the inspection, maintenance, and replacement of the control components 104 inside the housing 102a.

[0052] The bracket 102d is fixedly installed on the outer wall of the box 102a, and the bracket 102d and the box cover 102b are on different surfaces from the outer wall of the box 102a.

[0053] Preferably, the bracket 102d in this embodiment adopts a U-shaped design. The U-shaped bracket 102d is used to fix the receiving device, which can securely hang the device on the wall or other mounting surface. The U-shaped design reduces the installation footprint of the device, and can achieve reliable installation even in confined spaces.

[0054] Preferably, the solar panel 103a is movably connected to the surface of the housing 102a, meaning that the position of the solar panel 103a can be adjusted in real time according to the different positions of the sun, so as to support the 360° rotation adjustment of the solar panel 103a and further optimize the illumination angle.

[0055] In summary, the vibration sensor 101a is fixed to a key part of the reactor body by adhesive bonding. The angle and direction of the solar panel 103a are adjusted to ensure optimal sunlight exposure and sufficient power supply. The vibration sensor 101a is connected to the signal management unit 104b at the receiving end to ensure normal signal transmission. The reactor's operating status is monitored in real time via a mobile app or a terminal device at the monitoring center.

[0056] Example 3, referring to Figures 1 to 5 This is the third embodiment of the present invention. This embodiment further provides a vibration monitoring device, including an installation member 105 and a support member 106 disposed between the housing 102a and the solar panel 103a. The installation member 105 is movably connected to the solar panel 103a, and the support member 106 is movably connected to the installation member 105.

[0057] Mounting component 105 includes mounting bracket 105a, which is movably connected to solar panel 103a, and mounting hole 105b is provided on mounting bracket 105a.

[0058] Preferably, the mounting bracket 105a has second mounting holes 105c at both ends, and the solar panel 103a has third mounting holes 103b on both sides that mate with the second mounting holes 105c. After aligning the second mounting holes 105c and the third mounting holes 103b, the mounting bracket 105a and the solar panel 103a are secured by inserting pins, allowing the solar panel 103a to rotate on the mounting bracket 105a to achieve the best direct sunlight angle.

[0059] The support member 106 includes a support frame 106c fixedly connected to the housing 102a, a support base 106b fixedly disposed on the end face of the support frame 106c, and a rotating shaft 106a fixedly disposed on the end face of the support base 106b. The rotating shaft 106a is movably engaged with the mounting hole 105b.

[0060] Preferably, the support frame 106c is fixed to the upper surface of the housing 102a by bolt connection, and the support base 106b is fixed to the surface of the support frame 106c by bolt connection.

[0061] In summary, by aligning the third mounting holes 103b at both ends of the solar panel 103a with the second mounting holes 105c at both ends of the mounting bracket 105a, inserting the pins, and then aligning the mounting holes 105b on the mounting bracket 105a with the rotating shaft 106a, the solar panel 103a can be adjusted in real time according to the position of the sun to support 360° rotation adjustment of the solar panel 103a and further optimize the effect of the illumination angle.

[0062] Example 4, refer to Figures 1 to 11 This is the fourth embodiment of the present invention, which further provides an operating logic system and circuit diagram for a vibration monitoring module. It includes a vibration sensor 101a connected to a backup power supply unit and a power supply unit, and the vibration sensor 101a is also connected to a signal management unit, which is connected to a receiving terminal. Both the power supply unit and the backup power supply unit can provide power to the vibration sensor 101a. The power supply management unit monitors the power status of the backup power supply unit and automatically stops charging when the backup power supply unit is fully charged. After the vibration sensor 101a transmits a signal to the signal management unit, the signal is processed by the signal management unit and then transmitted to the receiving terminal.

[0063] Preferred, refer to Figure 7 The MAX485ESA+T chip connects pins 6 and 7 to pins A and B of the vibration sensor 101a, while pins 1 and 4 connect to the microcontroller's serial port 3 (receive and transmit pins). The STM32F407VET6 main control chip periodically sends data requests via the RS485 protocol to acquire data such as vibration velocity, vibration displacement, and vibration acceleration from the vibration sensor.

[0064] Reference Figure 8The data storage unit shown in the diagram is an SD data storage module. The SD data storage unit connects to the microcontroller via the SDIO protocol. DAT0 to DAT3 are connected to PC8 to PC10 pins of the microcontroller, CLK is connected to PC11, and CMD is connected to PD2. The microcontroller reads and writes to the SD card through the FATFS file system. When the microcontroller reads the vibration data and sets the value (e.g., a speed threshold of 10 mm / s), and the speed reaches 13 mm / s, the microcontroller automatically writes the data to the SD card. To view the data on the SD card, you can use a card reader on a computer or mobile phone, or request data through our provided wireless screen.

[0065] Figure 9 The hummingbird wireless communication unit shown is connected to the microcontroller's serial port pin 2 via pins 2 and 3. The microcontroller wirelessly transmits the vibration data stored in the SD card to the hummingbird unit on the wireless screen board via the serial port protocol, and can also receive commands wirelessly transmitted from the wireless screen board.

[0066] The AT24C02 is a commonly used electrically erasable programmable read-only memory (EEPROM) used to store threshold data such as speed, displacement, and time interval recorded to an SD card, as well as data on the total number of vibrations.

[0067] Figure 11 The audible and visual alarm unit circuit in the system issues an audible and visual alarm when it reads data from the vibration sensor unit that exceeds the threshold.

[0068] It should be noted that the receiving terminal includes, but is not limited to, a wireless display screen unit and software. The wireless display screen unit can set displacement, velocity, and SD card write interval thresholds for the microcontroller system, and can also read the current displacement, velocity, SD card write interval thresholds, and the total number of vibrations generated in the microcontroller system. On the second page of the screen, by clicking the "Get Data" button, recent vibration data from the SD card can be read, including the time of vibration, and the vibration velocity and displacement along the X, Y, and Z axes.

[0069] In summary, by attaching the vibration sensor 101a to the surface of the reactor, the vibration data of the reactor is obtained through the vibration sensor 101a. After the signal processing unit analyzes and processes the data from the vibration sensor 101a, the signal is transmitted to the final receiving end and alarm end through the communication unit. This allows the staff to check whether the vibration amplitude of the reactor exceeds the standard when needed. The audible and visual alarm can also compare the current real-time measurement value with a manually set threshold. When the real-time value exceeds the set threshold, the audible and visual alarm can also automatically sound an alarm.
