Abstract

PROBLEM TO BE SOLVED: To provide a dust filter automatic exchange apparatus which is capable of automatically exchanging the dust filter and which enables us to recognize that the residual quantity of the used part, which has not been located yet on the passage of wind of the dust filter, decreases to a predetermined quantity or less, even if the manager does not investigate actively.SOLUTION: BMC (base board management controller)15 detects the state of cloggings of the dust filter 2 based on the air flow and the temperature difference received from an air flow sensor 13 and a temperature sensor 14 respectively. When the value that has been received from the air flow sensor 13 and the temperature sensor 14 exceeds predetermined threshold conditions, BMC15 evaluates that the dust filter 2 is clogged, and then exchanges it for the dust filter 2 that has not been located yet on the passage of wind by operating the upper motor 3 and the lower motor 4. BMC15 also evaluates whether or not the residual quantity of the used part of the dust filter 2 that has been stocked inside the upper motor 3 and that has not been located yet on the passage of wind decreases to the predetermined amount or less. When the residual quantity decreases to the predetermined amount or less, BMC15 reports so.

  EMBODIMENT OF THE INVENTION Below, the form for inventing is demonstrated in detail with reference to drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  FIG. 1 is a diagram showing an external appearance of a server to which an automatic dustproof filter changing apparatus according to an embodiment of the present invention is applied. The front bezel of the server 1 incorporates roller-type upper motor 3 and lower motor 4 and a continuous sheet dustproof filter 2. The dust filter 2 covers the front surface of the server 1 whose use portion is a wind passage. Inside the upper motor 3, a used portion of the dust filter 2 that is not yet positioned on the front surface of the server 1 is stocked in a roll shape. Inside the lower motor 4, a used portion determined to be clogged with the dust filter 2 is wound up in a roll shape. The upper motor 3 and the lower motor 4 are rotated so that they are moved to the front side of the server 1 in the plane of the dust filter 2 positioned on the front side of the server 1 and are not yet positioned on the front side of the server 1. The dustproof filter 2 moves in the direction opposite to the part. As a result, the used part that has not yet been positioned in front of the server 1 moves to the front of the server 1. Further, the air that cools the server 1 flows from the front side to the back side of the server 1.

  In addition, the used part of the dust filter 2 that is not yet positioned on the front surface of the server 1 and the used part that is determined to be clogged may not be held in a roll shape. For example, it may be folded like a folding screen. Moreover, the dustproof filter 2 may be a single wafer type instead of a continuous sheet.

  FIG. 2 is a block diagram showing a configuration example of a server to which the dustproof filter automatic exchanging apparatus according to the embodiment of the present invention is applied. In the example of FIG. 2, the server 1 includes a dust filter 2, an upper motor 3, a lower motor 4, a motherboard 11, a CPU 12, an air volume sensor 13, a temperature sensor 14, a BMC (baseboard management controller) 15, and a cooling fan 16. Among them, the dust filter 2, the upper motor 3, the lower motor 4, the air volume sensor 13, the temperature sensor 14, and the BMC (base board management controller) 15 constitute a dust filter automatic changer. The BMC 15 controls the dust filter 2, the upper motor 3, the lower motor 4, the air volume sensor 13 and the temperature sensor 14.

  On the motherboard 11, a CPU 12, an air volume sensor 13, a temperature sensor 14, and a BMC 15 are installed.

  The CPU 12 is a CPU (Central Processing Unit) that controls the server 1. The dust filter automatic replacement device prevents the CPU 12 from being damaged due to a decrease in the air volume of the gas that cools the CPU 12 due to clogging of the dust filter 2 and the temperature inside the server 1 rising.

  The air volume sensor 13 detects the air volume of the gas flowing backward from the front surface of the server 1 generated by the cooling fan 16 and sends the value to the BMC 15.

  The temperature sensor 14 detects the temperature difference between the inside and the outside of the server 1 and sends the value to the BMC 15. When the external temperature can be regarded as almost constant, it is only necessary to detect the temperature inside the server 1.

  The BMC 15 detects the clogged state of the dustproof filter 2 based on the airflow value and the temperature difference value received from the airflow sensor 13 and the temperature sensor 14, respectively. The BMC 15 refers to a temperature difference and air volume table stored in advance, and the dust filter 2 is clogged when the values received from the air volume sensor 13 and the temperature sensor 14 exceed a predetermined boundary condition. Is determined. When the BMC 15 determines that the dust filter 2 is clogged, the BMC 15 operates the upper motor 3 and the lower motor 4 so that the use portion determined to be clogged with the dust filter 2 is still in the front of the server 1. Replace with unused parts. Further, the BMC 15 determines whether or not the remaining amount of the used portion of the dust filter 2 stocked in the upper motor 3 that has not been positioned on the front surface of the server 1 has become a predetermined amount or less, and the dust filter When the remaining amount of the used part that has not yet been positioned on the front surface of the server 1 is equal to or less than a predetermined amount, a notification is made. The BMC 15 controls the dustproof filter automatic changer independently of the CPU 12.

  FIG. 3 is a block diagram showing a functional configuration example of the BMC according to the embodiment of the present invention. The BMC 15 includes an air volume acquisition unit 151, a temperature difference acquisition unit 152, a clogging determination unit 153, a storage unit 154, an output unit 155, a remaining amount determination unit 156, and a notification unit 157.

  The air volume acquisition unit 151 acquires the value of the air volume of the gas generated by the cooling fan 16 from the air volume sensor 13.

  The temperature difference acquisition unit 152 acquires the value of the temperature difference between the inside and the outside of the server 1 from the temperature sensor 14.

  The clogging determination unit 153 determines whether the airflow value acquired by the airflow acquisition unit 151 and the temperature difference value acquired by the temperature difference acquisition unit 152 exceed the boundary condition stored in the storage unit 154. To do. If the boundary condition is exceeded, the clogging determination unit 153 determines that the dust filter 2 is clogged, and causes the output unit 155 to drive the upper motor 3 and the lower motor 4.

  The storage unit 154 stores in advance boundary conditions for determining whether or not to replace the dust filter 2.

  The output unit 155 outputs a signal for driving the upper motor 3 and the lower motor 4 in accordance with an instruction from the clogging determination unit 153.

  The remaining amount determination unit 156 is not yet positioned on the front surface of the server 1 of the dust filter 2 stocked in the upper motor 3 based on the number of times the output unit 155 has output signals for driving the upper motor 3 and the lower motor 4. It is determined whether or not the remaining amount of the used portion that has not been made has become a predetermined amount or less. When it is determined that the remaining amount is equal to or less than the predetermined amount, the remaining amount determination unit 156 causes the notification unit 157 to determine that the remaining amount of the used part that has not yet been positioned on the front surface of the server 1 of the dust filter 2 is the predetermined amount. Notify that The predetermined amount is, for example, an amount for one automatic exchange.

  The remaining amount determination unit 156 is not only the number of times the signals for driving the upper motor 3 and the lower motor 4 are output, but also, for example, on the front surface of the server 1 of the roll-shaped dust filter 2 stocked in the upper motor 3. It may be determined whether the remaining amount is equal to or less than a predetermined amount based on the roll diameter and weight of the used portion that has not yet been positioned.

  In response to an instruction from the remaining amount determination unit 156, the notification unit 157 notifies that the remaining amount of the used part that has not yet been positioned on the front surface of the server 1 of the dustproof filter 2 has become a predetermined amount or less. As a notification method, mail may be transmitted, a warning sound may be output, or a lamp such as an LED may be turned on.

  FIG. 4 is a diagram illustrating temporal changes in the airflow value detected by the airflow sensor and the temperature difference value detected by the temperature sensor according to the embodiment. In the graph of FIG. 4A, the vertical axis represents the air volume value detected by the air volume sensor 13, and the horizontal axis represents time. As shown in FIG. 4A, the value of the air volume detected by the air volume sensor 13 decreases exponentially due to clogging of the dustproof filter 2 that occurs over time. In the graph of FIG. 4B, the vertical axis represents the temperature difference value detected by the temperature sensor 14, and the horizontal axis represents time. As shown in FIG. 4B, the value of the temperature difference detected by the temperature sensor 14 increases exponentially due to the decrease in the air volume accompanying the clogging of the dustproof filter 2.

  The clogging determination unit 153 of the BMC 15 determines that the dustproof filter 2 is clogged when the air volume value and the temperature difference value exceed preset boundary conditions. When the clogging determination unit 153 determines that the dust filter 2 is clogged, the output unit 155 operates the upper motor 3 and the lower motor 4 to determine that the dust filter 2 is clogged. The part is replaced with a used part that is not yet located on the front of the server 1.

  When the dust filter 2 is replaced with a use part that has not yet been positioned on the front surface of the server 1, the value of the air volume detected by the air volume sensor 13 returns to the maximum value. And it decreases exponentially with the passage of time and the clogging that occurs mainly. Further, since the value of the air volume detected by the air volume sensor 13 has returned to the maximum value, the value of the temperature difference detected by the temperature sensor 14 becomes small. Then, the airflow increases exponentially due to the decrease in the air volume accompanying the clogging of the dustproof filter 2 again. This operation is repeated, and when the BMC 15 exceeds a preset boundary condition, the upper motor 3 and the lower motor 4 are operated to determine that the used part determined to be clogged with the dust filter 2 is still on the front surface of the server 1. By exchanging the parts for use which are not positioned, the value of the air volume and the value of the temperature difference are kept within a predetermined range.

  FIG. 5 is a diagram illustrating an example of the boundary condition between the air volume and the temperature difference according to the embodiment. FIG. 5A is an example of a data table that represents the boundary conditions between the air volume and the temperature difference stored in the storage unit 154. A circle in the figure is a flag indicating that the dustproof filter 2 is automatically replaced. In the example of FIG. 5A, if the air volume in the server 1 decreases, the dustproof filter 2 is automatically replaced even if the temperature difference between the inside and the outside of the server 1 is small. Further, if the temperature difference becomes large, the dustproof filter 2 is automatically replaced even if the air volume is large. Further, when the temperature inside the server 1 exceeds a predetermined temperature (for example, 70 ° C.), the server 1 may be forcibly terminated to protect the CPU 12. Note that the setting of the flag in FIG. 5A is an example, and the administrator can arbitrarily set the flag.

  The clogging determination unit 153 refers to such a data table, and includes a column corresponding to the air volume value acquired by the air volume acquisition unit 151 and a row corresponding to the temperature difference value acquired by the temperature difference acquisition unit 152. It is determined whether or not there is a flag (◯) in the intersecting box. If there is a flag, the clogging determination unit 153 causes the output unit 155 to drive the upper motor 3 and the lower motor 4 to indicate the used portion determined to be clogged in the dust filter 2 on the front surface of the server 1. Replace with a used part that is not located.

  Or you may set a boundary condition from the graph of the time change of an air volume and a temperature difference. FIG. 5B is a graph in which graphs showing changes over time in the air volume and the temperature difference when the dustproof filter 2 is not replaced are superimposed. The vertical axis represents the air volume and temperature difference values, and the air volume and temperature difference increase in the positive direction. The horizontal axis is time. Since the amount of dust adhering to the dust filter 2 gradually increases and the dust filter 2 is clogged, the air volume decreases exponentially with the passage of time. Accordingly, the temperature difference inside the server 1 increases exponentially.

  For example, the air flow value Pw and the temperature difference value Pt at the point where the air flow graph and the temperature difference graph intersect are set as boundary conditions (Pw, Pt). In other words, the clogging determination unit 153 determines that the airflow value acquired by the airflow acquisition unit 151 is equal to or less than Pw and / or the temperature difference value acquired by the temperature difference acquisition unit 152 is equal to or greater than Pt. The clogging determination unit 153 determines that the dust filter 2 is clogged. Then, the output unit 155 drives the upper motor 3 and the lower motor 4 to replace the used portion determined to be clogged with the dust filter 2 with a used portion that is not yet positioned on the front surface of the server 1. Note that the boundary condition in FIG. 5B is an example, and the administrator can arbitrarily set the boundary condition.

  FIG. 6 is a flowchart showing an example of the operation of automatic dust filter replacement according to the embodiment. The dust filter automatic replacement process starts when the power of the server 1 is turned on and ends when the power is turned off.

  First, when the power of the server 1 is turned on, the cooling fan 16 operates. The air volume acquisition unit 151 of the BMC 15 acquires the value of the air volume detected by the air volume sensor 13 (step S11). Moreover, the temperature difference acquisition part 152 acquires the value of the temperature difference in the server 1 which the temperature sensor 14 detected (step S12).

  The clogging determination unit 153 refers to the boundary condition stored in the storage unit 154 and determines whether or not the acquired air volume value and temperature difference value exceed the boundary condition (step S13). When the airflow value and the temperature difference value do not exceed the boundary condition (step S13; NO), the process returns to step S11, and steps S11 to S13 are repeated. When the airflow value and the temperature difference value exceed the boundary conditions (step S13; YES), the clogging determination unit 153 determines that the dustproof filter 2 is clogged. When the clogging determination unit 153 determines that the dustproof filter 2 is clogged, the output unit 155 operates the upper motor 3 and the lower motor 4, and determines the use portion determined to be clogged with the dustproof filter 2 as a server. It replaces | exchanges for the use part which has not been located in front of 1 yet (step S14).

  On the other hand, the remaining amount determination unit 156 determines whether or not the remaining amount of the used part that has not been positioned on the front surface of the server 1 of the dust filter 2 stocked in the upper motor 3 has become equal to or less than a predetermined amount (step) S15). When the remaining amount of the used part that is not yet positioned on the front surface of the server 1 of the dust filter 2 is not less than the predetermined amount (step S15; NO), the process returns to step S11, and steps S11 to S15 are repeated. When the remaining amount of the used portion of the dust filter 2 that has not yet been positioned on the front surface of the server 1 becomes a predetermined amount or less (step S15; YES), the remaining amount determination unit 156 informs the notification unit 157 of the dust filter 2 It is notified that the remaining amount of the used part that has not yet been positioned on the front surface of the server 1 has become equal to or less than a predetermined amount (step S16), and the process is terminated.

  As described above, according to the dust filter automatic replacement device of the embodiment, the dust filter 2 can be automatically replaced, and the used part that has not yet been positioned in the wind passage of the dust filter 2 The administrator can know that the remaining amount is less than a predetermined amount without actively going to check. As a result, maintenance is facilitated, so that the remaining part of the used part that has not yet been placed in the air flow path of the dust filter 2 for automatic replacement is prevented from being exhausted, and the cooling effect of the equipment to which the dust filter automatic replacement device is applied is prevented. Can be maintained.

  In the present embodiment, the decrease in the air volume in the server 1 is caused by the clogging of the dust filter 2, but in reality, there is a possibility that the cooling fan 16 is out of order. Therefore, the clogging determination unit 153 may determine whether or not the decrease in the air volume is due to the failure of the cooling fan 16.

  In this case, if the clogging determination unit 153 determines that the decrease in the air volume is due to the failure of the cooling fan 16, the notification unit 157 causes the administrator to notify the failure of the cooling fan 16. If the clogging determination unit 153 determines that the decrease in the air volume is due to the failure of the cooling fan 16, the temperature difference value acquired by the temperature difference acquisition unit 152 exceeds the boundary condition stored in the storage unit 154. It is determined that the dust filter 2 is not clogged.

  Further, whether or not the decrease in the air volume is due to the failure of the cooling fan 16 is determined based on, for example, the shape of a graph of the temporal change in the air volume. Actually, the decrease in the air volume due to the clogging of the dust filter 2 and the decrease in the air volume due to the failure of the cooling fan 16 are measured to create a temporal change pattern of the air volume as a criterion for the both, and the storage unit 154 in advance. It is good to memorize.

  Moreover, in this Embodiment, the case where the clogging of the dustproof filter 2 was determined based on the air volume in the server 1 and the temperature difference between the inside and the outside of the server 1 was described. The determination of clogging of the dustproof filter 2 may be performed based only on the air volume in the server 1 or may be determined based on only the temperature difference between the inside and the outside of the server 1. Good. When determining the clogging of the dust filter 2 based only on the temperature difference between the inside and the outside of the server 1, data indicating the correlation between the air volume and the temperature difference is stored in advance, and the air volume corresponding to the detected temperature difference is stored. Based on this, clogging may be determined. Further, when the external temperature can be regarded as substantially constant or when the external temperature is known, the clogging of the dustproof filter 2 may be determined based on only the internal temperature.

  In the present embodiment, the roll continuous sheet-like dust filter 2 is moved to the use position as the upper motor 3 and the lower motor 4 rotate. However, the dust filter 2 is a single wafer type. May be. In this case, the dust filter 2 is automatically replaced by, for example, a slide method.

  Moreover, in this Embodiment, the case where the dustproof filter automatic replacement apparatus of this invention was applied to a server was demonstrated to the example. The automatic filter replacement device of the present embodiment can also be applied to other devices including a wind generator, such as an air conditioner, an air cleaner, and a vacuum cleaner.

  The control program 39 controls the processing of the air volume acquisition unit 151, the temperature difference acquisition unit 152, the clogging determination unit 153, the storage unit 154, the output unit 155, the remaining amount determination unit 156, and the notification unit 157 of the BMC 15 illustrated in FIG. The processing is executed by using the unit 31, the main storage unit 32, the external storage unit 33, the operation unit 34, the display unit 35, the input / output unit 36, and the transmission / reception unit 37 as resources.

  In addition, the hardware configuration and the flowchart described above are merely examples, and can be arbitrarily changed and modified.

  The central part that performs control processing including the control unit 31, the main storage unit 32, the external storage unit 33, the internal bus 30 and the like can be realized by using a normal computer system, not a dedicated system. . For example, a computer program for executing the above operation is stored and distributed in a computer-readable recording medium (flexible disk, CD-ROM, DVD-ROM, etc.), and the computer program is installed in the computer. Thus, the BMC 15 that executes the above-described processing may be configured. Further, the BMC 15 may be configured by storing the computer program in a storage device included in a server device on a communication network such as the Internet and downloading the computer program by a normal computer system.

  Further, when the functions of the BMC 15 are realized by sharing of an OS (operating system) and an application program, or by cooperation between the OS and the application program, only the application program portion may be stored in a recording medium or a storage device. Good.

  It is also possible to superimpose a computer program on a carrier wave and distribute it via a communication network. For example, the computer program may be posted on a bulletin board (BBS: Bulletin Board System) on a communication network, and the computer program may be distributed via the network. The computer program may be started and executed in the same manner as other application programs under the control of the OS, so that the above-described processing may be executed.
