摘要
传统的沥青加热存在化油质量差、污染、耗能、成本高等诸多问题,采用太阳能光热转换高温加热沥青不失为很好的解决方法。为此,设计了高精度的太阳追光器,基于PSD位置传感器,以单片机C8051F021为控制核心,采用"光电"跟踪和"日历"跟踪相结合的策略。试验表明:该系统能够实现全天候的不低于0.2°的跟踪精度,且稳定性高,为达到沥青的高温工艺温度提供了必要条件。
Traditional asphalt heating is poor in quality of oiling,pollution,energy consumption and high cost problems,it is a good way to solve with adopting the solar-thermal conversion heating asphalt. For this purpose,a high pre-cision solar spotlight is developed. The single-chip C8051F021 is used to process the output signals of the PSD posi-tion sensor and control the motor to the solar tracking,the automatic track can be achieved by combining optical track-ing way calendar-reckoning method. Experiments show that tracking accuracy is not lower than 0.2° with all-weather, good stability,and it provides the necessary condition to reach the high temperature process of asphalt temperature.
