Abstract
The open system is not suitable for adoption in solar photovoltaic engineering because of
its inefficiency through analyzing the national sunshine duration table.Using the mixture
control system can enhance its track efficiency and make full use of solar energy
reasonably.The paper analyzed the two axle track principle emphatically,then proposed
the manual azimuth tracking and the automatic altitude angle tracking of 8
positions,educed hierarchical receive track principle,designed the software flow and a suit
of arbitrariness azimuth track system.Running results indicated that the system can
accomplish solar arbitrariness azimuth detection and tracking rapidly,fall running power
consume efficiently,reduce consume of mechanical structure,and have adjustable tracking
precision.It may obtain applications in solar photovoltaic engineering.
