Abstract: Focused on the issue that intelligent home is too expensive and poor user experience, Arm processor was combined with cloud server, joining the emerging cloud computing technology, building embedded Web server on CortexA8 processor, researching and designing a new type of smart home control system. The system was based on Cortex_A8 and embedded Linux operating system, using Web programming (CGI) as core technology, using B/S architecture model as the design structure and call CGI application through HTML. Users could interact with embedded hardware through Web browser in the PC or the mobile phone side, implementing the access and control intelligent household equipment status. The experiment result showed that: the data responds in time, the system runs stably, user accesses flexibility and it meets the demand for intelligent household with low cost.
