Voice control system and method of hydraulic support based on vocal cord vibration measurement

Abstract

The invention discloses a voice control system and method of a hydraulic support based on vocal cord vibration measurement. The method comprises the steps that the vocal cord vibration of an operatoris converted into a corresponding electrical signal through a vibration measurement unit; the electrical signal is amplified by a signal amplification unit, then converted by a vibration signal A/D conversion unit and then transmitted to a signal processing unit for analysis and processing to obtain a voice control command corresponding to the vocal cord vibration signal; and then the voice control command is compared and matched with a standard voice control command to indentify the vocal cord of the operator, the control signal corresponding to the vocal cord is sent to a hydraulic support controller wireless transceiver unit through a wireless signal transceiver unit, and at the same time, the hydraulic support controller wireless transceiver unit feeds back the status parameters of thehydraulic support. The voice control system of the hydraulic support based on the vocal cord vibration measurement is simple to operate, the operator only needs to give the voice control command, andthe hydraulic support can make corresponding actions; and accurate recognition of the voice control command in a noisy environment can be realized, and the voice control method can be used as an auxiliary control method to ensure the normal operation of the hydraulic support.

Description

technical field [0001] The invention belongs to the technical field of hydraulic support control, and in particular relates to a hydraulic support voice control system and method based on vocal cord vibration measurement. Background technique [0002] Hydraulic support is a kind of hydraulic power device that uses liquid pressure to generate support force and realizes automatic shifting for roof support and management. It is an indispensable supporting equipment for comprehensive mechanized coal mining. After years of technical accumulation, the control technology of hydraulic supports has been greatly developed. However, due to the relatively narrow working space of the fully mechanized mining face, especially when the workers cannot get close due to the occurrence of sidewalls, it is difficult or even impossible for the operators to directly operate the electro-hydraulic control buttons of the hydraulic support, so that the hydraulic support cannot be controlled normally. ...

Problems solved by technology

However, due to the relatively narrow working space of the fully mechanized mining face, especially when the workers cannot get close due to the occurrence of sidewalls, it is difficult or even impossible for the operators to directly operate the electro-hydraulic control buttons of the hydraulic support, so that the hydraulic support cannot be controlled normally. In addition, the existing The hydraulic support control requires multiple groups of buttons to control each action, which is not only complicated to operate, but also prone to misoperation due to insufficient light in the fully mechanized mining face

[0003] Voice control is a new type of non-contact control method. The existing voice control system generally uses a microphone to collect voice signals. However, due to the high noise in the fully mechanized mining face and the complex working environment, it is difficult to accurately recognize voice control commands.
