基于PLC的太阳能电池板追日系统

摘 要

本设计主要有控制器、检测设备、执行设备。控制器为可编程逻辑控制器，检测设备为光照传感器和模拟量的采集模块，执行设备为伺服电机、减速机构，设计一种使用PLC来自动追踪光能的太阳能电池板。首先，安装四颗光照传感器在太阳能电池上，进行光照角度检测和模拟量采集，在通过信号转换的方式将寄存器数据形式转换成模拟量信号，系统可以跟随太阳运行轨迹运动，能让太阳光与太阳能电池板垂直照射，提高接收效率。实现了一种太阳能自动跟踪系统模型。

关键词：可编程控制器，磁簧开关，伺服电机，太阳能电池板。

ABSTRACT

This design with programmable logic controller (PLC) as the controller, light sensors and analog acquisition module for testing equipment, servo motor, to carry out equipment, use of programmable logic controller (PLC) is designed to automatically track light solar panels, first by four light illumination Angle detection sensors, analog acquisition, converts signals to analog form to register data form, the system can follow the sun moves, can let the sun and solar panels vertical irradiation, improve the ef
