【Abstract】 The following sun on time solar heater machine and automatic control system were designed. According the earth running around sun theory, the angle of solar heater installation was calculated. Intel89C51 was selected as the controller. DS12887 counts the time and droved by step-motor. The orientation angle of sun was checked real time, and then the direction of solar heater was adjusted to the direct way of sunshine. The efficiency of heater collects heat energy was increased.更多还原
