Because the working temperature of the Intelligent Digital Distribution Terminal will be affected by the influence of the surrounding environment,and then leads the normal components cannot work normally. So a king of technology which can automatically detect temperature and real-time automatic control temperature arises at the historic moment.We finish controlling and adjusting the temperature inside the terminal in time by using the C8051F series of high-speed SoC microeontroller produced by Silicon Laboratories company and the DS1820 digital temperature gathering chip produced by DALLAS company combine with peripheral expansion circuit.%由于智能配电数字终端[1]内部的工作温度会受到周围环境的影响,从而导致箱体内部的一些正常元器件无法正常地工作。因此一种能自动检测温度并且实时自动调节温度的技术应运而生。通过使用Silicon Laboratories公司生产的C8051F系列的高速SoC单片机结合DALLAS公司的高精度的数字温度采集芯片DSl820。以及外围的扩展电路。完成对终端内的温度的实时的精确的控制和调节。
