Abstract: The present invention relates to a facility fault diagnosing method using a vibration characteristic, which comprises the steps of: dividing a vibration generated according to a fault of a facility into a plurality of vibration characteristics, configuring detailed vibration code items by subdividing the vibration characteristics, and associating and databasing the detailed vibration code items for each fault type to store the detailed vibration code items; receiving an input of a detailed vibration code item selection signal for the each vibration characteristic from a user; and determining a fault type of a facility on the basis of the each input detailed vibration code item and association information between the fault type and the detailed vibration code items. According to the present invention, a vibration fault is diagnosed through a combination of a plurality of detailed vibration components by breaking a scheme of diagnosing the vibration fault using only one vibration component so that a more reliable facility fault diagnosis can be performed.

Abstract: A facility fault diagnosing method uses a vibration characteristic. A vibration generated according to a fault of a facility is divided into a plurality of vibration characteristics. Vibration code items are configured by subdividing the vibration characteristics. The detailed vibration code items are associated and databased for each fault type to store the detailed vibration code items. An input of a detailed vibration code item selection signal is received for the each vibration characteristic from a user. A fault type of a facility is determined on the basis of the each input detailed vibration code item and association information between the fault type and the detailed vibration code items. The vibration fault is diagnosed through a combination of a plurality of detailed vibration components by breaking a scheme of diagnosing the vibration fault using only one vibration component so that a more reliable facility fault diagnosis can be performed.

Abstract translation: 设备故障诊断方法采用振动特性。 根据设施的故障产生的振动被分为多个振动特性。 振动代码项通过细分震动特性来配置。 详细的振动代码项目针对每种故障类型进行相关和数据库存储，以存储详细的振动代码项目。 针对来自用户的每个振动特性接收详细的振动代码项目选择信号的输入。 基于每个输入详细振动代码项和故障类型与详细振动代码项之间的关联信息来确定设备的故障类型。 通过使用仅一个振动分量来破坏诊断振动故障的方案，通过多个详细振动分量的组合来诊断振动故障，从而可以执行更可靠的设备故障诊断。
