The invention discloses a vibration and noise cooperative diagnostic instrument and diagnostic system, and relates to the field of train operation and maintenance safety guarantee, and the diagnostic instrument comprises a noise and vibration signal processing module, a central processor, a communication module and a power supply module for supplying power to each module. The noise and vibration signal processing module collects noise signals and vibration signals of a diagnosis object, preprocesses the signals and outputs the signals to the central processing unit. The central processing unit combines the noise signal and the vibration signal to jointly analyze the cause of noise generation of the diagnosis object, and the communication module transmits the cause of noise generation of the diagnosis object, namely the diagnosis result, to external equipment. Noise signals and vibration signals of a diagnosed object can be continuously collected, the reason of noise generation can be analyzed in combination with the vibration condition of the diagnosed object, and an accurate basis is provided for noise improvement.

    本发明公开了一种振动和噪声协同诊断仪及诊断系统,涉及列车运维安全保障领域,包括噪声和振动信号处理模块、中央处理器、通信模块以及为各个模块供电的电源模块。噪声和振动信号处理模块采集诊断对象的噪声信号和振动信号,并将信号进行预处理后输出至中央处理器。由中央处理器综合噪声信号和振动信号联合分析诊断对象产生噪声的原因,并由通信模块将诊断对象产生噪声的原因也即诊断结果传输至外界设备。对于诊断对象的噪声信号以及振动信号均能连续采集,并且能够结合诊断对象的振动情况分析噪声产生的原因,为改善噪声提供准确依据。
