Photovoltaic blind person audio-visual glasses

Abstract

The invention relates to a pair of photovoltaic blind person audio-visual glasses which can combine photovoltaic power supply and photovoltaic induction. The photovoltaic blind person audio-visual glasses comprise a solar photovoltaic panel, a storage battery, an induction probe, a monitoring converter and a controller, and are characterized in that the solar photovoltaic panel is respectively connected with the induction probe and the storage battery; the monitoring converter is connected with the induction probe; the controller is connected with the monitoring converter; and all the parts are directly mounted on a spectacle frame. The photovoltaic blind person audio-visual glasses disclosed by the invention can sensitively convert optical energy into electric energy by the solar photovoltaic panel; meanwhile, the induction probe utilizes photovoltaic electric power provided by the solar photovoltaic panel to induce the change of light in front of eyes; changed electric power parameters are sent out and output to the monitoring converter; the monitoring converter amplifies an electric signal and converts the electric signal into a sound signal with changed frequency; and then the sound signal with changed frequency is output to earphones arranged at the two sides of the glasses. A photovoltaic principle and an electronic technique are used for converting darkness change of the light into the change of sounds to provide information to a blind person to hear an around light environment. The appearance structure of an instrument is manufactured into a glasses shape, so that the photovoltaic blind person audio-visual glasses are attractive and elegant, are convenient to use, and facilitate popularization and application.

Description

technical field [0001] The present invention relates to a new type of glasses for the blind, in particular to a photovoltaic hearing glasses for the blind, which converts the change of light intensity into electrical parameters and then into the change of sound. Background technique [0002] At present, the technology of photovoltaic power supply equipment is very mature, and the circuit that uses photovoltaic phenomenon to sense the change of light intensity to control light is also very common, but it combines photovoltaic power supply and photovoltaic induction, and adopts unique photoacoustic It is the first of its kind to make hearing glasses for the blind with conversion circuits. Most blind people, due to the loss of vision, tend to have more sensitive hearing than ordinary people, but there is no instrument that can completely help them get rid of the darkness and help them avoid the damage caused by bumps and bumps. The country advocates the action of helping the d...

Problems solved by technology

It is also conceivable that the blind get help from helping the disabled. Their sensitive hearing advantage is not well used to make up for the lack of vision.
