基于PLC的碟式太阳能跟踪控制系统设计

Design of disc type solar tracking control system based on programmable logic controller

设计了一种以FX3U系列PLC为控制核心的太阳能自动跟踪控制系统。该跟踪控制系统将视日运动轨迹跟踪与传感器跟踪相结合,即第一级采用视日运动轨迹跟踪,初步跟踪太阳的运行轨迹,第二级采用传感器跟踪校正,并采用双轴式跟踪调整装置。系统还设计了时间显示模块,能够显示实时时间,同时也可以对时间进行实时调整。

This paper introduces a solar energy automatic tracking control system, which use FX3U series PLC as the control kernel, to greatly improve solar energy utilization rate. The system combines the advantages of two techniques： firstly, apply sun trajectory tracking technique to track the sun trajectory and then utilize the technique sensor tracking to revise it accurately, meanwhile an adjusting device of dual axle type tracking is employed in this system. A time display module, which can be used both to dispaly the real-time time and to adjust time on real-time, is aslo introduced into this system.
