Cab inside and outside interaction method and device

Abstract

The invention provides a cab inside and outside interaction method. The cab inside and outside interaction method comprises the following steps: acquiring an original audio signal of a first space; removing a noise signal in the original audio signal to obtain a target audio signal; and outputting the target audio signal to a second space; wherein the first space is one of a space inside a cab or a space outside the cab, and the second space is the other one of the space inside the cab or the space outside the cab. According to the cab inside and outside interaction method and device provided by the invention, the target audio signal is obtained by de-noising the original audio signal collected in the first space, and the target audio signal is output to the second space, so that the working personnel inside and outside the cab can eliminate noise interference during communication, interactive and transmitted information is more complete and clearer, and the interactive working efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of intelligent vehicles, and in particular to a method and device for interaction between the interior and exterior of a cab. Background technique [0002] For vehicles such as working machinery, there will be noise with large amplitude during operation. For example, the engine, crawler or mechanical arm of some working machinery will produce large noise when working, so the operator in the cab It is more difficult to communicate with the commander outside the cab, and it is more disturbed by noise. [0003] At present, in order to overcome the interference of vehicle noise, the following methods are mainly used at present: 1. Stop the vehicle and restart it after the communication between the staff inside and outside the cab, but this is a waste of time and will reduce the starting motor and battery life of the vehicle. Service life; 2. Open the window of the cab, so the noise is still very loud, a...
