Remote voice control system and method used for engineering machinery

Abstract

The invention discloses a remote speech control system used in a construction machinery. The system is connected with a master controller of the construction machinery. The system comprises a speech reception device which receives speech signals and converts the received speech signals into analog electrical signals; a wireless signal transmitter installation transmits the analog electrical signals to a wireless signal reception device at the far end which converts the analog electrical signals into digital signals; a speech recognition device searches speech simulation signals corresponding to the digital signals in a built-in database; a control command reforming unit searches and transmits control commands corresponding to the speech imitation signals to the master controller of the construction machinery. The invention also discloses a remote speech control method used in the construction machinery. The remote speech control system and the method thereof are used for realizing the speech control on the construction machinery.

Description

technical field [0001] The invention relates to the field of control, in particular to a remote voice control system and method for engineering machinery. Background technique [0002] In the field of large-scale construction machinery, when controlling construction machinery with multi-section booms or mechanical arms with bending structures, in order to ensure the safety of operators, wireless remote control devices are generally used to keep operators away from the car body for control. . For example, control the boom of the concrete pump truck to expand or retract, control the movement of the crane boom, etc. [0003] refer to figure 1 , is a structural diagram of the wireless remote control device described in the prior art. [0004] The wireless remote control device includes: a wireless remote controller 1a including control buttons and a control handle, a receiver 1b installed on a mechanical vehicle, a mechanical vehicle controller 1c, and a driving mechanism 1d....
