摘要
对HX_(D)2型机车机械间进行声学信号采集,确定机车运行正常工况条件下机械间内的声学信号类型,对典型声信号和声事件的信号特点进行分析归纳。实测数据分析表明,在HX_(D)2型机车机械间内采集声信号条件较好,对各典型声事件信号段进行标记提取,利用声纹特征可有效识别出风机、电笛、减速排气等声事件。
With acoustic signals collected from the machine room of HX_(D)2 locomotive,the type of acoustic signals is determined in the machine room under normal operation conditions of the locomotive,and the signal characteristics of typical acoustic signals and events are analyzed and summarized.The analysis of measured data shows that the conditions for collecting acoustic signals are good in the machinery room of HX_(D)2 locomotive.With the signal sections of typical acoustic events marked and extracted,the acoustic events such as fan,electric whistle and deceleration exhaust can be effectively identified by their voiceprint characteristics.
