Training device for automatic tracking motion control system Vocational Training Equipment Smart Grid Training Equipment

1 Product overview
1.1 Overview
This training device This system can simulate the motion control process of automatic tracking of the solar panel in the photovoltaic power generation system to automatically track the angle of direct sunlight, so that students have a preliminary intuitive understanding of the working principle and working mode of the automatic tracking system. The analog light source is driven by a stepping motor to move in an arc, the light intensity sensor is driven by a servo motor, and the PLC collects real-time feedback light intensity change signals to control the light intensity sensor to always track the position of the strongest point of the analog light source. Through related experiments, students can cultivate the corresponding knowledge and skills, which are suitable for the teaching and skill training assessment of related professions in higher vocational schools, colleges, secondary vocational schools and technical schools.
