Due to the shortcomings of the winter heating system in North China, the paper designs an indoor intelligent temperature control system based on ARM-Linux platform of embedded systems and fuzzy control technology. The system uses DS18B20 and ZigBee wireless networking technology to complete the collection of multi-point temperature. The system also uses fuzzy control technology to achieve precise control of room temperature. The establishment of the QT user interface optimizes the environment of human-computer interaction. By using GPRS technology, the system's remote control, the system becomes a great convenience for the user. The implementation of the system will play an important role to reduce energy waste and improve people's quality of life.
