半自动追光太阳灶

Semi-automatic chasing solar cooker

对于燃料短缺并且经济落后的西部地区,为了解决当地人民能源不足的问题,开发高效清洁的太阳能显得尤为重要。目前,西部地区如甘肃、西藏等地的农牧民应用太阳能主要通过太阳灶实现,而现有的纯机械式太阳灶存在精确度低和操作性难问题,自动跟踪式太阳灶存在结构复杂、成本高等方面问题。针对现有的太阳灶存在费用高、操作难等问题,通过对现有太阳灶的调查研究,设计开发了一种半自动追光太阳灶。基于现有机械式太阳灶增加语音提示调控模块,利用四象限光敏电阻比较法对光线进行定位,将光线照射在不同光敏电阻上的面积和强度产生的电压差信号输入单片机,利用单片机控制语音模块输出具体语音提示,例如:“请向上调节”,之后进行人工调节;当调整到最佳位置时,会提示:“调节完成”以示调整结束。设计旨在充分利用清洁廉价的太阳能,降低能耗、解决西部地区能源短缺问题,并弥补现有太阳灶的缺点,实现节能减排的理念。

In the western region where fuel is scarce and economically backward, it is particularly important to develop efficient and clean solar energy in order to solve the problem of local people's energy shortage. At present, the application of solar energy by farmers and herdsmen in the western regions such as Gansu and Tibet is mainly realized by solar cookers, while the existing purely mechanical solar cookers have low precision and difficult operation problems, and the automatic tracking type solar cookers have complex structures and costs. Higher aspects. Aiming at the problems of high cost and difficult operation of existing solar cookers, a semi-automatic chasing solar cooker was designed and developed through investigation and research on existing solar cookers. This work is based on the existing mechanical solar cooker to increase the voice prompt control module. The four-quadrant photoresistor comparison method is used to locate the light, and the voltage difference signal generated by the area and intensity of the light on different photoresistors is in put into the single-chip microcomputer, and controlled by the single-chip microcomputer. The voice module outputs specific voice prompts, for example:“Please adjust upwards”, and then manually adjust;when adjusted to the best position, it will prompt:“Adjustment completed” to indicate the end of the adjustment. The design aims to make full use of clean and cheap solar energy, reduce energy consumption and solve the energy shortage problem in the western region, and make up for the shortcomings of existing solar cookers and realize the concept of energy saving and emission reduction.
