Conference room intelligent control method based on voice recognition

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.

Non-contact audio equipment volume controller and control method thereof

The invention provides a non-contact audio equipment volume controller and a control method thereof. The non-contact audio equipment volume controller comprises: an electronic volume control chip, a front end circuit and a follow-up circuit. The non-contact audio equipment volume controller also comprises: a photoelectric sensor and control module possessing at least two infrared sensors; a single chip microcomputer, which is used to receive a photoelectric sensor and control module signal, determine an infrared signal sequence received by the at least two infrared sensors and output a control coding signal. Ports of outputting two channel control coding signals of the single chip microcomputer are respectively connected with a SDA port and a SCL port of the electronic volume control chip. During a regulation and control process, a user can only move one part of the body in a control scope of to the infrared sensors of the audio playback equipment to adjust the volume. Therefore, the user who is inconvenient to operate can use the audio playback equipment conveniently.

Hearing aid capable of rotatably adjusting volume and volume adjusting method

The invention is applicable to the technical field of hearing assistance. The invention provides a hearing aid capable of rotatably adjusting volume and a volume adjusting method. The hearing aid comprises an earphone. The earphone comprises a housing. An MCU and a potentiometer are arranged in the shell. The shell is provided with a knob fixing shell. The knob fixing shell is sleeved with a knobrotating shaft, the rotating shaft is provided with a cross-shaped protrusion. The cross-shaped protrusion is rotationally connected with a volume adjuster. The volume adjuster comprises a rotating part and a fixing part. The rotating part is connected with the cross-shaped protrusion in a matched mode. The fixing part is provided with a welding spot. One end of the welding spot is electrically connected with the potentiometer, and the other end of the welding spot is electrically connected with the rotating part. When the volume adjusting device is used, the knob is rotated, the knob drives the rotating part to rotate through the cross-shaped bulge on the rotating shaft, so that the resistance of the volume adjuster is changed, the potentiometer converts the resistance change into a voltage change signal, the voltage change signal is transmitted to the MCU, and the MCU adjusts the volume of the hearing aid according to the voltage change signal. The device is small in size, attractiveand convenient for old patients to operate.
