摘　　要：文章主要叙述以单片机为主要控制系统,由光敏电阻与LM339构成定值差分光敏传感器。由555定时器与光敏组成的单稳型定时电路采集阳光,减少灯光或阴天对系统的干扰,这样系统只会在晴天设定的光照强度下寻光。本系统创新性之处在于,用555定时器构成一个定时器间歇性继电器吸合供给系统,设立按键实现对整个系统的手动控制。追光技术是能源发展的需要,是发展清洁能源,高效利用太阳能的必经之路。因此,阳光追踪技术存在着很大的潜力,对其开发研究有着重要的价值。This paper mainly describes a system which use the single-chip microcomputer as the main control system with the photosensitive resistor and LM339 constituting a fixed value differential photosensitive sensor. The single stable timing circuit compared by the 555 timer and photosensitive composition collects the sun and reduces the interference from light or cloudy, so that the system will only seek light in the light intensity of the sun set. The innovation of the system is a timer intermittent relay supply system constituted by 555 timer,and the system sets up the keys to achieve the manual control of the whole system. The technology of the solar panel autotracking system is the only way which must be passed to the development of clean energy and efficient use of solar energy. Therefore,Technologies of the solar panel autotracking system have great potential, and the research to them has important value.
