常検出装置を提供することを目的とする。The present invention has been made in view of the above-mentioned problems of the conventional technology, and when there is a change in the sound of the cooling fan, an alarm is issued to the outside to notify the abnormality of the cooling fan, and the cooling effect of the cooling fan is reduced. To provide a cooling fan abnormality detection device that can prevent a temperature rise in a housing of an electronic device and prevent damage to electronic components by allowing the cooling fan to be replaced before the cooling fan is replaced.

発生回路とを備えるという構成を採用し、これによって
上記目的を達成しようとするものである。For this reason, the present invention includes a converter that inputs the sound generated by a cooling fan installed in the housing of an electronic device and converts it into an electrical signal, and a converter that inputs the electrical signal from the converter. A configuration comprising: an abnormal sound determination circuit that determines whether the generated sound is abnormal and outputs an alarm signal when abnormality is determined; and an alarm generation circuit that inputs the alarm signal from the abnormal sound determination circuit and generates an alarm. The aim is to achieve the above objectives.
以下、本発明の一実施例を第１図に基づいて説明する。 An embodiment of the present invention will be described below with reference to FIG.
第１図は、本発明の一実施例を示すブロック図であり、

てなる。FIG. 1 is a block diagram showing one embodiment of the present invention,
The cooling fan abnormality detection device of this embodiment includes a converter 3 that inputs sounds 2, 2 generated from a pair of cooling fans 1.1 provided inside the housing of an electronic device and converts them into electrical signals;
an abnormal sound determination circuit 4 which inputs the electric signal from the converter 3, determines whether or not there is an abnormality in the sound 2 generated by the cooling fan 1, and outputs an alarm signal when an abnormality is determined; The interface circuit 5 is provided as an alarm generation circuit which inputs an alarm signal from the terminal and generates an alarm sound 6 to the outside.
冷却ファン１は、グリースの劣化またはベアリングの損

常音判定回路４で検出され、警報信号がインターフェー
ス回路５に出力される。これにより、インターフェース
回路５は、外部に警報音６を発生する。The cooling fan 1 generates abnormal noise before the rotation speed decreases when the grease deteriorates or the bearings are damaged. Therefore, when an abnormal sound is generated from the cooling fan 1, the electrical signal of the converter 3 changes, the change is detected by the abnormal sound determination circuit 4, and an alarm signal is output to the interface circuit 5. As a result, the interface circuit 5 generates an alarm sound 6 to the outside.
一方、冷却ファン１より異常音が発生されない状態では
、変換器３の電気信号に変化が生じないため、異常音判
定回路４は警報信号を出力せず、インターフェース回路
５は警報音６を発生しない状態となる。On the other hand, when no abnormal sound is generated by the cooling fan 1, no change occurs in the electrical signal of the converter 3, so the abnormal sound determination circuit 4 does not output an alarm signal, and the interface circuit 5 does not generate an alarm sound 6. state.
以上のように本実施例によれば、冷却ファン１に劣化が

の電子部品の損傷を未然に防止できる。As described above, according to this embodiment, when the cooling fan 1 deteriorates and the sound 2 changes, the alarm sound 6 is output to the outside, so the rotation speed of the cooling fan 1 decreases and the electronic device Deterioration of the cooling fan 1 can be detected early before the temperature inside the body increases, making it possible to replace the cooling fan 1 and improve the performance of electronic components such as ICs used in electronic devices. Damage can be prevented.
また異常音判定回路４に他の閾値をもたせることによっ

時も、冷却ファン１よりの音が無くなるので、冷却ファ
ン１の異常を検出することができる。Furthermore, by providing the abnormal sound determination circuit 4 with another threshold value, even when the cooling fan 1 stops due to reasons other than deterioration or failure, the sound from the cooling fan 1 disappears, so that an abnormality in the cooling fan 1 can be detected. Can be done.
