Abstract

The invention discloses a point switch fault detection device based on acoustics, and effectively solves the problem that in the prior art, when a point switch fault is detected through acoustics, the obtained classification result is not accurate, and a signal acquisition module acquires an acoustic signal sent after a target point switch is started, and the collected acoustic signals are transmitted to the acoustic signal preprocessing module in a wireless transmission mode, the acoustic signals are preprocessed and then transmitted to the acoustic signal classification module, the signal classification module outputs and displays classification results, and the target switch machine refers to a switch machine for detection. Therefore, the influence on the accuracy of the acoustic signal classification module in acoustic signal classification is avoided, the anti-interference capability of the acoustic signal classification module in actual use is improved, and the phenomenon of lack of preprocessing of the acoustic signals is also avoided.

Description

Technical field[0001]The present invention relates to the field of failure detection, particularly a sound-based swivel stripping failure detecting device.Background technique[0002]In response to the urgency of the high-speed rail system to ensure driving safety, the practice of mechanical faults in the turnover machine, the traditional technology is to monitor the operation current and power value of the turning machine, according to the operation current curve and power value analysis. To determine the failure of the turning machine, this method has problems with insufficient detection techniques, the operation current is not easy to collect and the acquisition process is prone to interference.[0003]Therefore, in the prior art, universities have begun to use acoustic detection to failure in the laboratory, and use SVM to classify the acoustic signal. SVM is a two-point algorithm, that is, the default turning machine is only two In this way, although this method has achieved good r...
