With the development of science and technology,
Modern home environment is paid more and more
attention. The number of functions has been growing;
nevertheless smart appliances have formed "isolated
islands” of the information, which become the
bottleneck in the development of smart appliances. In
additionˈoperation near the appliances is required in
traditional control mode, which limits the scope of
activities. Reference[1] sums up the development status
and analyses exiting problems of remote control system
of smart appliancesˈand then puts forward that the future
trends of system will be reflected in the following three
aspects: Networking technology from wired to wireless,
diversification of remote control mode, energy-saving
and smart will lead the new trend.
Therefore, diversification of remote control mode is
the inevitable trend of development of smart appliances.
It's an important part of smart home.
Remote control system of smart appliances mainly
consists of two parts: household internal control network
and remote control network.
Traditional household internal control network is
generally implemented through wiring. This method is
not only troublesome but also has poor scalability.
Wireless network technology becomes new trends with
its simple and convenient networking. ZigBee
technology characterizes good security, high reliability,
low cost, low power consumption, large network
capacity. With these features, ZigBee is widely used in
smart home system.
Traditional remote mode in reference [9] uses the
PC as a local server, which has a high cost. Moreover
this method requires PC in the state of power on and
communicating, in addition, hardware and software that
may interfere with communicating tasks can not be run
on the PC.
We have developed a remote control system of
smart appliances based on wireless sensor network,
applying the rapid developing mobile network and
Internet to the field of remote control. The system uses a
high-performing, low-costing, low-consuming chip
STM32 as information processing center, without the
high-costing PC as a local server. ZigBee technology is
adopted to form household internal control network
instead of the cumbersome wiring. This method requires
no wiring, has a short installation period and is
convenient to move and add network node. Traditional
key an infrared control is included but reformed to make
a diverse and various control modes. Each remote
control mode has account login and information
matching settings to add to security of the system
