本発明は強制空冷式情報処理装置におけるファン異常検
出方式に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application'] The present invention relates to a fan abnormality detection method in a forced air cooling type information processing device.
従来の強制空冷式情報処理装置は、第２図に示すように
、ユニット部１０の下部にファン部１１を有し、ユニッ
ト部１０の冷却を行う構成となっている。As shown in FIG. 2, a conventional forced air cooling type information processing apparatus has a fan section 11 at the bottom of a unit section 10, and is configured to cool the unit section 10.
ファン部１１の障害は、ファン部１１の回転状態の目視
及び異常音を確認するか、情報処理装置の交流電源遮断
後に、個々のファンを手動により回転させ、その状態に
より異常か正常かを判断している。If there is a failure in the fan unit 11, check the rotating state of the fan unit 11 visually and check for abnormal sounds, or manually rotate each fan after the AC power supply to the information processing device is cut off, and determine whether it is abnormal or normal based on the status. are doing.
上述した従来のファン異常検出方式は、目視。 The conventional fan abnormality detection method described above is visual inspection.
異常音及び手動による回転状態の確認によるため、異常
検出が簡単に出来ないという欠点があった。There was a drawback that abnormality detection could not be easily detected because of the abnormal sound and manual confirmation of the rotational state.

回転時間の監視により、ファン異常を検出することを特
徴とする。The fan abnormality detection method of the present invention, in a forced air cooling type information processing device having a fan unit, includes a rotation detection sensor unit that detects the rotation state of the fan, and a rotation detection sensor unit that monitors the signal from the rotation detection sensor unit over time to detect the rotation state of the fan. A fan abnormality detection section that detects an abnormality, and a battery section that supplies power to the rotation detection sensor section and the fan abnormality detection section, and by monitoring the rotation time of the fan after the AC power supply of the information processing device is cut off, It is characterized by detecting fan abnormality.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.
第１図は本発明の一実施例のブロック図であり、回転検
出センサ部２．ファン異常検出部４およびバッテリ一部
が設けられている。FIG. 1 is a block diagram of an embodiment of the present invention, in which the rotation detection sensor section 2. A fan abnormality detection section 4 and a part of a battery are provided.
ユニット部１はファン部３により強制空冷され、ファン
異常検出部４と回転検出センサ部２には、バッテリ部６
より電源供給ライン７を介し電源が供給されている。The unit part 1 is forcedly air-cooled by the fan part 3, and the fan abnormality detection part 4 and the rotation detection sensor part 2 have a battery part 6.
Power is supplied via a power supply line 7.
情報処理装置の交流電源を遮断するとファン部３に対す
る電源供給がなくなり、ファンが正常の時は回転惰性に
より一定時間回転を続ける。ファンの回転部が異常の時
は、正常時の回転惰性による回転より短時間で回転が停
止する。When the AC power of the information processing device is cut off, the power supply to the fan unit 3 is cut off, and when the fan is normal, it continues to rotate for a certain period of time due to rotational inertia. When the rotating part of the fan is abnormal, it stops rotating in a shorter time than normal rotation due to rotational inertia.
この状態、つまり交流電源遮断後のファンの回転状態を
回転検出センサ部２で検出し、センサ信号６としてファ
ン異常検出部４に送信する。This state, that is, the rotational state of the fan after the AC power supply is cut off, is detected by the rotation detection sensor section 2 and transmitted as a sensor signal 6 to the fan abnormality detection section 4.
ファン異常検出部４はセンナ信号６を時間監視し一定時
間より短かい場合にはファン異常として保守者に知らし
める。The fan abnormality detection section 4 monitors the senna signal 6 for a period of time, and if the time is shorter than a certain time, it notifies the maintenance person that the fan is abnormal.
以上説明したように本発明は、情報処理装置交流電源を
遮断した後のファンの回転惰性による回転状態を検出し
てファンの異常検出を行う構成とすることにより、簡単
にファンの異常検出を行うことができる効果がある。As described above, the present invention is configured to detect an abnormality in the fan by detecting the rotational state due to rotational inertia of the fan after the AC power source of the information processing device is cut off, thereby easily detecting an abnormality in the fan. There is an effect that can be done.
