Abstract

The invention discloses a visible light compound eye positioner. According to the invention, hemisphere face of a semispherical compound eye is divided into 32400 small grids; each grid is provided with a simple eye which comprises a convex lens and a cylindrical fiber connected with the bottom of the convex lens; each simple eye is connected with two photoresistor modules which are a column resistor module and a row resistor module in adjacent position; a circuit module is formed by the photoresistor modules and is externally connected with a DSP processor through a voltage sensor and powered by the DSP processor. According to the invention, visible light is effectively collected and processed; responding speed and precision in positioning are enhanced; the positioner has a small volume,light weight, simple structure and low energy consumption, and is convenient to assemble and apply.

Description

technical field [0001] The invention relates to a visible light positioning system, which is suitable for visible light positioning applications such as solar photovoltaic and photothermal ray tracing positioning. Background technique [0002] At present, solar tracking has been widely used in various solar energy application systems, and the tracking and positioning technology of sunlight has developed rapidly. The general tracking and positioning of sunlight to adjust the orientation of solar panels is performed by photosensitive or heat-sensitive components and some control systems. It is composed of photosensitive or heat-sensitive components arranged at different positions on the solar panel, and the sensing amount of sunlight at different angles is different, and the data is transmitted to the control system to correct the orientation of the solar panel. Because the sunlight light path does not pass through the intermediate medium other than the air and directly contac...
