Auditory signal identification method and device, equipment and storage medium

Abstract

The invention provides an auditory signal recognition method and device, equipment and a storage medium, and relates to the technical field of signal processing. The method comprises the steps: acquiring a training audio signal of a target position acquired by audio acquisition equipment; adopting an identification algorithm to detect whether an audio feature of starting whistle blowing exists inthe training audio signal; if the audio feature of starting whistle blowing exists, recording the time of starting whistle blowing; adopting an identification algorithm to detect whether an audio feature of ending whistle blowing exists in the signal after the time of starting whistle blowing in the training audio signal; if the audio feature of ending whistle blowing exists, obtaining a whistle feature of the training audio signal; and determining an auditory signal type corresponding to the training audio signal by adopting a preset auditory signal type configuration parameter according to the whistle feature. According to the invention, the error probability in the auditory signal training process of shunting operation personnel can be reduced, and the auditory signal training efficiency is improved.

Description

technical field [0001] The present application relates to the technical field of signal processing, in particular, to an auditory signal recognition method, device, equipment and storage medium. Background technique [0002] In the production process of railway transportation, some purposeful movement of locomotives can be collectively referred to as shunting operations. Through shunting operations, locomotives can be moved on station lines or other lines. For a long time, the shunting operation has become the "soft underbelly" of locomotive safety management due to factors such as the inability of the locomotive monitoring device to receive ground shunting signals for effective monitoring, and the complex operating environment of the station. In the process of shunting operation, the corresponding auditory signal is mainly issued by the operator. Based on the auditory signal, the locomotive driver controls the locomotive to perform corresponding operations. The safety of th...

Problems solved by technology

[0003] At present, most of the training for operators in the railway industry still stays in the traditional "teacher leading apprentice" method. The master conducts manual teaching, and the apprentice imitates and learns the operation of the master. Whether the apprentice's imitation is correct in this process can only be determined by the master. making subjective judgments

[0004] However, in shunting operations, different auditory signals have different whistle characteristics, which are various and difficult to remember. Using the traditional "teacher with apprentice" model for training is error-prone and inefficient
