Conference room intelligent control method based on voice recognition

InactiveCN103064379AHigh degree of intelligenceAdjust the volumeSpeech recognitionProgramme total factory controlRS-485Digital mixing console

The invention discloses a conference room intelligent control method based on voice recognition, and belongs to the field of intelligent office working. The conference room intelligent control method based on the voice recognition aims to solve the problems that existing office facilities in a conference room have respective defects on the control of screen display, sound equipment, lighting and air-conditioning, and are low in degree of intelligence. The conference room intelligent control method includes the following steps of collecting a voice command in the conference room, converting the voice command to characters through voice recognition software, and enabling a command analysis program to continuously match the recognized characters and a prestored command. If the prestored command is a control command of the screen display, then one way of a plurality of display signal source hosts is chosen to enable the control command to pass; if the prestored command is a control command of the sound equipment, the volume can be adjusted through a universal serial bus (USB) interface to drive a digital mixing console; if the prestored command is a control command of the lighting, a relay is driven to control the on-off state of lights; and if the prestored command is a control command of the air-conditioning, a startup or shutdown command is sent to a hang ceiling type air-conditioning indoor unit through a recommend standard (RS) 232 interface or an RS 485 interface. Therefore, the startup or shutdown of a certain hang ceiling type air-conditioning indoor unit can be independently controlled.
