Abstract: Towards the demand of intelligent iterative development of the smart home system at present，this paper analyzes the current researches on technical realization of smart home system control，proposes the method of design and implementation of smart home system control based on Python Django. With Python Django，the designs of system structure，communication protocols，gateway system are realized. Combined with the CAN network，this paper realizes complete application of smart home system. Through the scalability analysis of security module of the smart home system，it is illustrated that Python Django is more suitable for rapid iteration development of smart home system.

Key words: Python Django, smart home, extendability
