Study Of Smart Home System Based On ARM

Currently, "The Internet of Things" has become a hot topic to cause the attention of people. It uses certain communication technologies (such as RFID,GPS) in accordance with the agreement protocol will connect to the Internet articles, exchange information, so as to achieve the monitoring and management, intelligent identification, location and track. Actually, Smart Home Systems is a part of "The Internet of Things", which allows devices within the family network by some means of communication, so that within the family "material objects connected" and then through the home gateway to connect with the Internet.Proposes a Smart Home System plan based on ARM, in the system ARM processor is the main controller. Transplanting Web server into the main controller as a home gateway so remote users can monitor and control home equipments, considering safety problems of remote monitoring was designed based on the speaker recognition of login method.First, from the basic knowledge of relevant technology, introduces the research of the relevant ARM processor, the principle of Zigbee and WiFi protocol, the theoretical research of speaker recognition technology and its feasibility is verified. According to the design of system method chosen host - target machine cross-development environment, S3C2440A as the main controller, JN5139 as Zigbee networking chip, VT6656 as WiFi transmission module, and select Linux operating system as the corresponding software development platform. Then detailed study the main controller and home networking, mainly aimed at two wireless home network design Zigbee/WiFi conversion protocol, and use speaker identification technology in the remote users login method.The Smart Home System used ARM as the primarily controller, and choose the wireless transmission technology combination of Zigbee and WiFi, the whole system using wireless communication to overcome the defect of cable transmission. The Zigbee/WiFi protocol improve the network transmission rate,and prohibit illegal users access to monitoring system through the remote user login system. It has some frontier and practical in the field of domestic industry technology development and applications.
