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。
The article describes the microcontroller as the main control system, the photosensitive resistor and the LM339 constitute a differential value photosensitive sensor. The 555 timer and photosensitive monostable timing circuit sunshine collection to reduce light or cloudy interference on the system, so the system will only set the light intensity in sunny days to find light. The innovation of this system lies in that it uses 555 timer to form a timer intermittent relay pull-in supply system and set up keys to realize the manual control of the whole system. Chasing light technology is the development of energy needs, is the only way to develop clean energy, efficient use of solar energy. Therefore, sunshine tracking technology has great potential and is of great value to its research and development.
