Description

Technical Field

[0001] The present invention relates to a fan system and a monitoring method for the fan system, and in particular to a fan system and a monitoring method capable of providing early warning notifications according to the operating status of the fan. Background Art

[0002] Most devices (such as production equipment, personal computers, and laptops) use fans for cooling. Fan cooling allows devices to operate smoothly. However, fans are often considered low-reliability components. If a fan malfunctions or fails, the device may overheat, shut down, or become damaged. Therefore, fans must be replaced or repaired before any malfunction or failure occurs. Therefore, developing fan monitoring technology that can provide early warning notifications based on the fan's operating status is a key research and development focus for those skilled in the art. Summary of the Invention

[0003] The present invention relates to a fan system and a monitoring method for the fan system, which can provide early warning notification according to the operating status of the fan.

[0004] The fan system of the present invention includes a fan device and a controller. The fan device includes a fan unit, a detector, and a memory. The detector detects the operating status of the fan unit during operation to obtain raw operating data corresponding to the operating status. The memory is coupled to the detector. The memory is operated to record the raw operating data and store a data protocol. The controller provides a monitoring request, causing the memory to respond to the monitoring request to provide the raw operating data and the data protocol to the controller, and convert the raw operating data into operating status data using the data protocol. The controller also provides an early warning notification signal based on the operating status data. When the raw operating data is provided to the controller, the raw operating data stored in the memory is erased.

[0005] The monitoring method of the present invention is applicable to a fan system. The fan system includes a fan device and a controller. The fan device includes a fan unit and a memory. The monitoring method includes: driving the fan unit and detecting the operating status of the fan unit during operation to obtain raw operating data corresponding to the operating status; recording the raw operating data in the memory; using the controller to provide a monitoring request, causing the memory to respond to the monitoring request and provide the raw operating data and a data protocol to the controller, and using the data protocol to convert the raw operating data into operating status data; when the raw operating data is provided to the controller, erasing the raw operating data stored in the memory; and using the controller to provide an early warning notification signal based on the operating status data.

[0006] Based on the above, in the fan system and monitoring method of the present invention, the controller issues a monitoring request to receive raw operating data and a data protocol via memory, and uses the data protocol to convert the raw operating data into operating status data. This allows the controller to provide an early warning notification signal. Furthermore, when the raw operating data is provided to the controller, the raw operating data stored in the memory is erased. This significantly reduces the memory storage space requirements of the fan system.

[0044] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0045] Please refer to Figure 1 , Figure 1FIG1 is a schematic diagram of a fan system according to a first embodiment of the present invention. In this embodiment, the fan system 100 includes a fan device 110 and a controller 120. The fan device 110 includes a fan unit 111 and software 112. The fan unit 111 may, for example, be a cooling component that uses a motor to drive fan blades, thereby achieving a cooling effect. The fan device 110 can communicate with the controller 120 through the software 112. Specifically, the software 112 records the raw operating data ORD of the fan device 110 during operation. The raw operating data ORD may include, for example, at least one of the drive current value, drive voltage value, ambient temperature value, and operating time of the fan device 110 during operation. The controller 120 may, for example, be an electronic device with computing capabilities. The controller 120 and the fan device 110 may communicate via wired or wireless communication methods well known to those skilled in the art. The controller 120 provides a monitoring request REQ to the fan device 110. In this embodiment, the software 112 responds to the monitoring request REQ by providing the original operating data ORD and the data protocol PTC to the controller 120. The data protocol PTC is used to indicate the encoding rule or format type of the original operating data ORD. The controller 120 uses the data protocol PTC to convert the original operating data ORD into operating status data OSD. In this embodiment, the controller 120 also provides an early warning notification signal SN based on the operating status data OSD. The early warning notification signal SN can be at least one of an audio signal, an optical signal, and a text signal. Based on the determination of the operating status data OSD, the controller 120 can provide and issue the early warning notification signal SN before an abnormality or failure occurs. This allows the user (or administrator, maintainer) to repair or replace the fan device 110 based on the early warning notification signal SN. In this embodiment, the fan device 110 can use multiple physical components to implement the above-mentioned operations of the software 112.

[0046] In this embodiment, the controller 120 may periodically provide the monitoring request REQ. In some embodiments, the controller 120 provides the monitoring request REQ based on an external operation or an external instruction.

[0047] Furthermore, in this embodiment, the format of the raw operating data ORD is a first data format suitable for the fan device 110. The format of the operating status data OSD is a second data format recognizable by the controller 120. The controller 120 can convert the raw operating data ORD in the first data format into the operating status data OSD recognizable by the controller 120 using the data protocol PTC. In other words, the data format of the fan device 110 in the fan system 100 can differ from the data format of the controller 120. Thus, the fan system 100 is not limited to fan devices 110 and controllers 120 having the same data format.

[0048] In some embodiments, the fan system 100 may include multiple fan devices, and the number of fan devices of the present invention is not limited to this embodiment. In some embodiments, the data formats of the multiple fan devices may not be exactly the same. For example, the multiple fan devices include a first fan device and a second fan device. The data format of the first fan device is different from the data format of the second fan device. The controller 120 may convert the first operating raw data of the first fan device into first operating status data that can be recognized by the controller 120 based on the first data protocol of the first fan device. The controller 120 may convert the second operating raw data of the second fan device into second operating status data that can be recognized by the controller 120 based on the second data protocol of the second fan device.

[0049] Please also refer to Figure 2 as well as Figure 3 , Figure 2 is a schematic diagram of a fan system according to a second embodiment of the present invention. Figure 3 This is a flow chart of a monitoring method according to a second embodiment. In this embodiment, a fan system 200 includes a fan device 210 and a controller 220. The fan device 210 includes a fan unit 211, a detector 212, and a memory 213. The memory 213 is coupled to the fan unit 211 and the detector 212. In step S110, the fan unit 211 operates in response to a drive parameter DPR. The detector 212 detects the operating status of the fan unit 211 during operation to obtain raw operating data ORD corresponding to the operating status. In this embodiment, the memory 213 stores the drive parameter DPR. The fan unit 211 can receive the drive parameter DPR via the memory 213 and operate in response to the drive parameter DPR to produce a cooling effect. In this embodiment, the raw operating data ORD includes, for example, at least one of the drive current value used to drive the fan unit 211, the drive voltage value used to drive the fan unit 211, the ambient temperature value, and the operating time. Therefore, the detector 212 includes, for example, at least one of a current sensor, a voltage sensor, a temperature sensor, and a timer. The memory 213 may be any form of data storage component.

[0050] In step S120, the operation original data ORD is recorded in the memory 213. That is, the memory 213 is operated to record the operation original data ORD.

[0051] In this embodiment, the memory 213 also stores the data protocol PTC. In step S130, the controller 220 provides the monitoring request REQ to the fan device 210. The memory 213 responds to the monitoring request REQ to provide the operating raw data ORD and the data protocol PTC to the controller 220. The controller 220 converts the operating raw data ORD into the operating status data OSD using the data protocol PTC. The detailed implementation of the controller 220 converting the operating raw data ORD into the operating status data OSD can be described by Figure 1 The embodiments of the present invention provide sufficient teachings, so they will not be repeated here.

[0052] Next, in step S140, the operation original data ORD stored in the memory 213 is erased. That is, when the operation original data ORD is provided to the controller 220, the operation original data ORD stored in the memory 213 is erased. For example, when the controller 220 receives the data protocol PTC and the complete operation original data ORD, the operation original data ORD stored in the memory 213 will be erased by the controller 220. For another example, the fan device 210 will erase the operation original data ORD stored in the memory 213. In this embodiment, the detector 212 and the memory 213 can be implemented as follows. Figure 1 The operation of software 112.

[0053] It is worth mentioning that the controller 220 can periodically provide the monitoring request REQ. Therefore, the controller 220 can provide the monitoring request REQ based on a preset period (for example, 1 to 5 minutes, but the present invention is not limited thereto). Therefore, in step S140, the operating raw data ORD stored in the memory 213 is erased based on the preset period. Therefore, it can be seen that the storage space required by the memory 213 only needs to accommodate the data protocol PTC, the drive parameters DPR, and the operating raw data ORD of a single preset period. In this way, the storage space requirement of the memory 213 can be significantly reduced.

[0054] In step S150, the controller 220 provides a warning notification signal SN based on the operating status data OSD. For example, the controller 220 records a preset value (e.g., a preset current value). The preset value is lower than the driving current value when the fan unit 211 experiences an abnormality or fails. Therefore, once the driving current value in the operating status data OSD is determined to be greater than the preset value, the controller 220 provides and issues a corresponding warning notification signal SN. In this way, based on the judgment of the operating status data OSD, the controller 220 can provide and issue the warning notification signal SN before the fan unit 211 experiences an abnormality or fails, allowing the user to repair, maintain, or replace the fan device 110 based on the warning notification signal SN.

[0055] Please also refer to Figure 4 as well as Figure 5 , Figure 4 is a schematic diagram of a fan system according to a third embodiment of the present invention. Figure 5 This is a flow chart of the monitoring method shown in the third embodiment. In this embodiment, the fan system 300 includes a fan device 310 and a controller 320. The fan device 310 includes a fan unit 311, a detector 312, a memory 313 and a timer 314. The memory 313 is coupled to the fan unit 311, the detector 312 and the memory 313. In step S210, the fan unit 311 starts to be driven. In addition, the timer 314 starts timing. In this embodiment, while the fan unit 311 is running, the timer 314 will continuously time the running time of the fan unit 311. In this embodiment, the timer 314 will continuously time the running time of the fan unit 311 to provide running raw data ORD2 corresponding to the length of the running time. In this embodiment, the detector 312, the memory 313 and the timer 314 can be implemented as follows Figure 1 The operation of software 112.

[0056] In step S220, the detector 312 detects the operating status of the fan unit 311 during operation to obtain the operating raw data ORD1. The operating raw data ORD1 includes, for example, at least one of a driving current value, a driving voltage value, and an ambient temperature value.

[0057] In step S230, the fan device 310 determines whether it has received a monitoring request REQ. If it has not received the monitoring request REQ, the fan device 310 proceeds to step S220 to continuously obtain the raw operating data ORD1 and ORD2. On the other hand, if it has received the monitoring request REQ, the fan device 310 causes the memory 313 to provide the raw operating data ORD1 and ORD2 and the data protocol PTC to the controller 320 in step S240. Furthermore, in step S240, the controller 320 converts the raw operating data ORD1 and ORD2 into operating status data OSD using the data protocol PTC.

[0058] In step S250 , the operation original data ORD1 and ORD2 stored in the memory 313 are erased.

[0059] In step S260, the controller 320 determines whether the operating status data OSD is greater than a preset value. If the operating status data OSD is greater than the preset value, the controller 320 provides a warning notification signal SN in step S270. On the other hand, if the operating status data OSD is less than or equal to the preset value, the fan device 310 continues to perform step S220 to continuously obtain the raw operating data ORD1 and ORD2.

[0060] In this embodiment, based on design requirements, when the warning notification signal SN is provided, the fan device 310 will continue to obtain the original operation data ORD1 and ORD2, or stop obtaining the original operation data ORD1 and ORD2.

[0061] Further examples are given to illustrate the implementation details of judging the running status data. Please also refer to Figure 4 as well as Figure 6 , Figure 6 is a waveform diagram of operating status data according to an embodiment of the present invention. In this embodiment, the operating status data OSD includes the total operating time ts of the fan unit 311. In this embodiment, the total operating time ts is correlated with the raw operating data ORD2 provided by the timer 314. The raw operating data ORD2 is shown as curve C1. In this embodiment, the controller 320 determines whether the total operating time ts is greater than a preset time td. When the total operating time ts is greater than the preset time td, the controller 320 provides an early warning notification signal SN. In this embodiment, the early warning notification signal SN is a notification signal corresponding to the total operating time ts being greater than the preset time td.

[0062] In this embodiment, the predetermined time length td is set to be shorter than the expected life span of the fan unit 311 or equal to the maintenance cycle.

[0063] In this embodiment, the controller 320 provides a monitoring request REQ based on a preset period (e.g., 1 to 5 minutes, but the present invention is not limited thereto). Therefore, the controller 320 receives multiple total operating time lengths ts corresponding to the multiple time points after periods P1 to P5. In other words, the multiple total operating time lengths ts at the multiple time points are roughly the sampling results of curve C1. In this embodiment, the multiple total operating time lengths ts received at the multiple time points after periods P1 to P4 are determined to be less than the preset time length td. Therefore, the controller 320 does not provide a warning notification signal SN. On the other hand, the total operating time length ts received at the time point after period P5 is greater than the preset time length td. This indicates that the total operating time length ts of the fan unit 311 is about to reach its expected lifespan or requires maintenance. Therefore, the controller 320 provides a warning notification signal SN at the time point after period P5.

[0064] In some embodiments, the controller 320 can determine that the total operating time length ts will equal the preset time length td at time t1 based on the total operating time lengths ts received at multiple time points after periods P1 to P4. Therefore, the controller 320 provides the early warning notification signal SN at time t1.

[0065] Please also refer to Figure 4 as well as Figure 7 , Figure 7 is a waveform diagram of operating status data according to another embodiment of the present invention. In this embodiment, the operating status data OSD includes a driving current value Idr used to drive the fan unit 311. In this embodiment, the driving current value Idr is associated with the operating raw data ORD1 provided by the timer 314. The operating raw data ORD1 is shown as curve C2. In this embodiment, the controller 320 determines whether the driving current value Idr is greater than a preset current value Id. When the driving current value Idr is greater than the preset current value Id, the controller 320 provides an early warning notification signal SN. In this embodiment, the early warning notification signal SN is a notification signal corresponding to the driving current value Idr being greater than the preset current value Id.

[0066] In this embodiment, the preset current value Id is set to be smaller than a limit current value. The limit current value is a current value that may damage the fan unit 311.

[0067] In this embodiment, the controller 320 provides a monitoring request REQ based on a preset period. Therefore, the controller 320 receives a plurality of driving current values ​​Idr corresponding to the plurality of time points at a plurality of time points after the periods P1 to P5. That is, the plurality of driving current values ​​Idr at the plurality of time points are roughly the sampling results of the curve C2. In this embodiment, the plurality of driving current values ​​Idr received at a plurality of time points after the periods P1 to P4 are judged to be less than the preset current value Id. Therefore, the controller 320 does not provide an early warning notification signal SN. On the other hand, the driving current value Idr received at the time point after the period P5 is greater than the preset current value Id. This indicates that an abnormality has occurred in the driving current value Idr. Therefore, the controller 320 provides an early warning notification signal SN at the time point after the period P5.

[0068] Please also refer to Figure 4 as well as Figure 8 , Figure 8 FIG3 is a waveform diagram of operating status data according to another embodiment of the present invention. In this embodiment, the operating status data OSD includes the ambient temperature value Temp. In this embodiment, the ambient temperature value Temp is associated with the operating raw data ORD1 provided by the timer 314. The operating raw data ORD1 is shown as curve C3. In this embodiment, the controller 320 determines whether the ambient temperature value Temp is greater than a preset temperature value Tpd. When the ambient temperature value Temp is greater than the preset temperature value Tpd, the controller 320 provides a warning notification signal SN. In this embodiment, the warning notification signal SN is a notification signal corresponding to the ambient temperature value Temp being greater than the preset temperature value Tpd.

[0069] In this embodiment, the preset temperature value Tpd is set to be less than a limit temperature value. The limit temperature value is a temperature value that may damage the fan unit 311 or a temperature value that may damage the device.

[0070] In this embodiment, the controller 320 provides a monitoring request REQ based on a preset period. Therefore, the controller 320 receives multiple ambient temperature values ​​Temp corresponding to the multiple time points at multiple time points after periods P1 to P5. In other words, the multiple ambient temperature values ​​Temp at the multiple time points are roughly the sampling results of curve C2. In this embodiment, the multiple ambient temperature values ​​Temp received at multiple time points after periods P1 to P4 are judged to be less than the preset temperature value Tpd. Therefore, the controller 320 does not provide an early warning notification signal SN. On the other hand, the ambient temperature value Temp received at the time point after period P5 is greater than the preset temperature value Tpd. This indicates that the cooling capacity of the fan unit 311 may be insufficient or ineffective. Therefore, the controller 320 provides an early warning notification signal SN at the time point after period P5.

[0071] Please return Figure 4 as well as Figure 5 In an embodiment, the operating status data OSD includes a driving current value (such as Figure 7 The driving current value Idr shown), driving voltage value, ambient temperature value (such as Figure 8 The ambient temperature value Temp) and the total running time (such as Figure 6 Therefore, the controller 320 judges at least two of the driving current value, the driving voltage value, the ambient temperature value, and the total operating time length to obtain a judgment result, and provides a corresponding warning notification signal SN based on the judgment result.

[0072] Please refer to Figure 9 , Figure 9 4 is a schematic diagram of a fan system according to a fourth embodiment of the present invention. In this embodiment, the fan system 400 includes a fan device 410, a controller 420, and a monitoring terminal 430. The fan device 410 includes a fan unit 411 and software 412. The monitoring terminal 430 and the controller 420 can communicate by wired communication or wireless communication methods well known to those skilled in the art. The coordinated operation of the fan device 410 and the controller 420 in this embodiment can be performed by Figures 1 to 8The above embodiments provide sufficient teachings, so they will not be repeated here. In this embodiment, the monitoring terminal 430 collects the warning notification signal SN1 via the controller 420 and issues the warning notification signal SN1. The user can repair or maintain the fan device 410 based on the warning notification signal SN1 issued by the controller 420 or the monitoring terminal 430. In addition, the monitoring terminal 430 collects the warning notification signal SN2 from other controllers (not shown) and issues the warning notification signal SN2. Therefore, the monitoring terminal 430 can issue the warning notification signals SN1 and SN2. In this embodiment, the monitoring terminal 430 can be a background host, a server, or other device.

[0073] In some embodiments, based on design requirements, the fan system 400 may include multiple fan devices and multiple controllers, but is not limited to this embodiment.

[0074] In summary, in the fan system and monitoring method of the present invention, the controller provides a monitoring request to receive raw operating data and a data protocol via memory, and uses the data protocol to convert the raw operating data into operating status data. In this way, the controller can provide and issue an early warning notification signal before an abnormality or failure occurs, allowing the user to repair or replace the fan device based on the early warning notification signal. The data format of the fan device can be different from the data format of the controller. In this way, based on the data protocol, the fan system is not limited to fan devices and controllers with the same data format. In addition, when the raw operating data is provided to the controller, the raw operating data stored in the memory is erased. In this way, the storage space requirement of the fan system's memory can be significantly reduced. In some examples, the fan system also includes a monitoring terminal. The user can repair or maintain the fan device based on the warning notification signal issued by the controller or the monitoring terminal.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
