中文摘要:
      为提高太阳能集热器板的能量吸收率,设计了基于西门子S7-1200PLC的双轴伺服太阳能跟踪系统.该系统采用视日轨迹跟踪方案,根据相关天文学公式和参数计算出太阳的实时位置,控制伺服电机带动集热器板实时跟踪太阳.采用SIMATIC HMI精简面板组态友好的人机界面,操作简单,便于监视和管理. 详细介绍了控制系统的原理及硬件构成和系统的软件设计.试验结果表明: 太阳跟踪器运行稳定可靠,能适应各种复杂环境条件.
英文摘要:
      In order to improve the energy absorption rate of solar thermal collector plate,a two-axe solar tracking control system is designed based on programmable logic controller (PLC) of Siemens S7-1200. A sun tracking scheme is proposed to control servo motor running to drive solar collector tracking the sun' real-time position,which is calculated out by relevant astronomy formula and parameters. A friendly interface using SIMATIC HMI panel is presented. It can be operated simply for user to monitor and manage the system. The design of control system is presented in detail according to the operational principle of solar-tracker,as well as the development of software and hardware. The solar tracking experiments indicate that the solar tracker operates reliably and is able to work under complex weather conditions.
