Embodiment Construction

[0021] The technical solution of the present invention will be further described below through specific embodiments,

[0022] 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.

[0023] In view of the above problems, it is necessary to adjust the overall loudness of the audio signal in the working environment, the method is as follows, the overall linear reduction:

[0024] A loudness gain constant C is preset, and when the collected digital signal...

Abstract

The invention discloses an audio signal linear processing method for remote control of a working machine, comprising the following steps of: firstly, acquiring an audio signal of a working site of theworking machine through a sound sensor, transmitting the audio signal to a remote cab, and playing the audio signal to a driver in the remote cab after the audio signal is processed. The processing mode of the sound signal is as follows: setting the loudness of the audio signal as L, presetting a loudness gain constant C, and multiplying the loudness L by the loudness gain constant C; furthermore, the loudness gain constant C can be adjusted within a certain range, the adjusting range of the loudness gain constant C is C1-C2, wherein C1 is larger than or equal to 1 and smaller than C2 or C2 is larger than C1 and smaller than or equal to 1, and C1 and C2 are both preset. By applying the method, interference with 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 linear 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 operati...
