Embodiment Construction

[0024] The technical solution of the present invention will be further described below through specific embodiments,

[0025] The audio signal at the working site of the operating machine is collected by the sound sensor and transmitted to the remote cab. After the sound signal is processed, it is played to the driver in the remote cab. The overall loudness of the audio signal in the working environment is high or low, and the duration is long. These signals are of reference value to the driver, but because the overall loudness is too high, it will interfere with the driver's driving and be harmful to the driver's hearing health. ; or the driver cannot hear clearly because the overall loudness is too low.

[0026] In order to solve the above problems, it is necessary to adjust the overall loudness of the audio signal in the working environment. The method is as follows: high-loudness reduction, that is, for the driver to better listen to the sound of the scene, only the high-l...

Abstract

The invention discloses an audio signal processing method for remote control of an operating machine, which comprises the following steps: firstly, acquiring an audio signal of a working site of the operating machine through a sound sensor, transmitting the audio signal to a remote cab, processing the sound signal, and playing the processed sound signal to a driver in the remote cab, wherein the processing mode of the sound signal is as follows: the loudness of the audio signal is set as L, a loudness gain constant CH and a loudness threshold LH are preset, and when the loudness L of the soundis greater than LH, the loudness L is multiplied by the loudness gain constant CH; furthermore, the loudness threshold value LH is equal to (e1 + e2) * AGE, e1 is the environment coefficient of the working site and comprises the number information of the mechanical devices working at the same time in the working site, e2 is the weather condition and comprises the wind speed and precipitation information of the current working site, and AGE is the age of a driver; by means of the method, interference to a driver can be reduced, the working efficiency is improved, and meanwhile hearing damage to the driver can be avoided.

Description

technical field [0001] The invention belongs to the technical field of industrial remote control, and in particular relates to an audio signal processing method for remote control of operating machinery. Background technique [0002] Construction machinery and other operation machinery for special occasions are widely used in various construction sites, and have the characteristics of harsh working environment and high importance of work. In some special environments, the safety and health of operators of operating machinery are threatened, for example, in extremely cold, underwater, toxic, and radiation environments, or in dangerous environments such as collapse and collapse at the construction site. [0003] In order to solve the problem of operating machinery in a special environment, the existing technology generally adopts a remote control method, that is, the driver controls the working machinery in a remote and safe environment to carry out construction operations, an...
