Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to a monitoring device, in particular to a monitoring device of a rotating device. BACKGROUND
[0002] For a rotating device such as a heat dissipation fan, if there is a need to continuously monitor the operation, evaluate the service life, detect abnormalities in real time, etc., an accelerometer is usually arranged on the rotating shaft or bearing of the fan to measure the acceleration value and Kurtosis of the rotating shaft or bearing. Using the measured acceleration value and Kurtosis, in addition to the monitoring parameters such as rotational speed change, intensity, etc., the performance change of the heat dissipation fan can be further confirmed by referring to the reference Kurtosis. In addition, if the threshold value is set for each parameter based on empirical analysis or experimental data, when a certain parameter exceeds the threshold value, the need for real-time maintenance, replacement of parts, such as bearing wear, abnormal rotating state of the rotating shaft, etc. can be known in real time, so that specialized maintenance personnel can respond in real time to ensure that the rotating device under their responsibility can continue to operate normally.
[0003] However, there are many abnormal situations that may occur during the operation of the rotating device, and simply referring to the parameters measured by the accelerometer arranged on the rotating shaft or bearing for monitoring cannot completely and effectively monitor other components of the rotating device. Moreover, many abnormal conditions cannot be detected by the parameters measured by the accelerometer, so the existing monitoring technology is not perfect and an effective solution that can monitor more components in all directions is needed. SUMMARY
[0004] The purpose of the present application is to provide a monitoring device for a rotating device that can evaluate multiple parameters as a whole to achieve all-around monitoring.

[0007] The monitoring device for the rotating device of the present invention, wherein the first detection information sensed by the sensing unit includes acceleration value, displacement value, and velocity value.

[0009] The beneficial effects of the present invention are as follows: by means of the accelerometer and the electrical sensor of the sensing unit, the first detection information related to the motion state and the second detection information related to the electrical parameters can be obtained, thereby comprehensively monitoring the operation of the rotating device. Furthermore, when there is an abnormality in the first detection information or the second detection information, the microcontroller can send the strain drive signal to enable the response unit to adjust the operating state of the rotating device in real time to maintain the normal operation of the rotating device.

[0011] Figure 2 This is a sectional view illustrating one type of rotating device used in this embodiment;
[0012] Figure 3 This is a block flowchart illustrating the operation of the microcontroller, sensing unit, and response unit in the embodiment described. Detailed Implementation
[0013] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0014] See Figure 1 This is an embodiment of the monitoring device for the rotating device of the present invention. In this embodiment, the rotating device 1 is a monitoring device for the rotating device of the present invention. Figure 2To illustrate this with the example of a cooling fan, the rotating device 1 includes a frame 11 defining a mounting space 110, an operating module 12 mounted in the mounting space 110, and a circuit board 13 connected to the operating module 12. It should be noted that although this embodiment describes the rotating device 1 as a cooling fan, in practice, the rotating device 1 can also be any other component whose primary operating mechanism is rotation, such as a motor. This embodiment includes a microcontroller 2 adapted to be mounted on the circuit board 13 for controlling the rotation of the operating module 12, a sensing unit 3 adapted to be mounted on the circuit board 13, and a response unit 4 connecting the sensing unit 3 and the microcontroller 2.
[0015] Specifically, the microcontroller 2 is a processing chip that can be pre-programmed with logic, perform calculations and processing accordingly, and issue corresponding control signals. Thus, the microcontroller 2 can receive relevant parameters sensed by the sensing unit 3 and pre-program corresponding control logic to form the control center of this embodiment.
[0016] See also Figures 1 to 3 The sensing unit 3 includes an accelerometer 31 connected to the microcontroller 2 to generate a first detection information, an electrical sensor 32 electrically connected to the microcontroller 2 to generate a second detection information, and a timer 33 connected to the accelerometer 31 and the electrical sensor 32 to provide a time-related parameter. The first detection information detected by the accelerometer 31 includes acceleration, displacement, and velocity values; while the second detection information detected by the electrical sensor 32 includes voltage, current, resistance, and power values. The time-related parameter provided by the timer 33, in conjunction with the first and second detection information, forms a time-related parameter change trend, providing the microcontroller 2 with more diverse reference data.
[0017] It is worth noting that, since the sensing unit 3 is mounted on the circuit board 13 located inside the rotating device 1, compared to the conventional case where sensing components such as accelerometers are mounted on external structures such as shafts or bearings, the accelerometer 31 can detect subtle vibration differences more accurately and delicately. Furthermore, the electrical sensor 32 can more directly obtain electrical signals from the circuit board 13, reducing interference that may occur during signal transmission, thus ensuring that the microcontroller 2 receives more accurate electrical signals and makes more precise judgments.
[0018] After the sensing unit 3 outputs the first detection information and the second detection information along with the time-related parameters to the microcontroller 2, the microcontroller 2 can generate a strain drive signal to adjust the rotation state of the rotating device 1 according to the pre-written control logic. The response unit 4 is a mechanism for receiving the strain drive signal and converting it into a physical control action. Specifically, it can be a variable resistor that can adjust the rotation speed of the operating module 12, or a switch that can switch the operating mode of the operating module 12. Therefore, after receiving the strain drive signal, the rotation speed of the operating module 12 can be reduced or increased due to factors such as excessive rotation speed, excessive vibration, reduced voltage, excessive current, etc.
[0019] It should be noted that although the response unit 4 can directly adjust the operation module 12 to respond in real time, if the sensing unit 3 has detected that the rotation of the rotating device 1 is not good and that physical maintenance or even replacement is required, the surrounding maintenance personnel can be notified at the same time and perform the corresponding maintenance work.
[0020] Furthermore, considering that the strain drive signal output by the microcontroller 2 still depends on the pre-written calculation and processing program, to further improve the response performance of the microcontroller 2, an artificial intelligence autonomous learning mechanism can be introduced. Based on each process of receiving the first detection information and the second detection information and generating the strain drive signal, the microcontroller 2 can autonomously perform inductive calculations and optimize the logic program, thereby improving the monitoring performance of the rotating device 1 in this embodiment.
[0021] In summary, the embodiment of the monitoring device for the rotating device of the present invention, through the sensing unit 3 mounted on the circuit board 13, can more directly obtain the first detection information related to the motion state and the second detection information related to the electrical parameters, thereby comprehensively monitoring the operating state of the rotating device 1. Furthermore, when necessary, the device can use the strain drive signal processed by the microcontroller 2 to adjust the operating state of the rotating device 1 in real time through the response unit 4, thereby maintaining the normal operation of the rotating device 1. Therefore, the objective of the present invention is indeed achieved.
