Design of temperature control technology for intelligent power distribution digital terminal based on C8051F021
Since the operating temperature inside the intelligent power distribution digital terminal [1] is affected by the surrounding environment, some normal components inside the box cannot work properly. Therefore, a technology that can automatically detect the temperature and automatically adjust the temperature in real time has emerged. By using the C8051F series high-speed SoC microcontroller produced by Silicon Laboratories, combined with the high-precision digital temperature acquisition chip DS1820 of DALLAS, and peripheral expansion circuits, the real-time and accurate control and adjustment of the temperature inside the terminal is completed.
