The invention discloses a realization method for a smart home gateway based on three-
network integration. The smart home gateway is integrated with various kinds of communication protocols such as a Wi-Fi protocol, a ZigBee protocol, a TCP / IP protocol and a switch control protocol. The smart home gateway is also a cross-multi-terminal smart home gateway and has strong robustness and stability. The smart home gateway includes a central processor module,
peripheral expansion interfaces, a power source / reset module, a high-definition touch screen, a GPRS module, a Zigbee module, a WI-FI module, an
Ethernet module, a
video monitoring module as well as
application software and a
user management and
authentication unit which are in a
service layer of the central processer module. With the smart home gateway based on three-
network integration of the invention adopted, a user can perform
remote management and control on the gateway through smart terminals such as a computer, a
mobile phone and a PDA; and through preparatory work of prophase indoor wiring, home gateway equipment
model selection, and local end VALN business division, service of flexible access of digital televisions,
the Internet and home appliances can be facilitated.
