Abstract: With the rapid development of Internet of Things(IOT) technology in recent years,all kinds of house appliances have been connected by wireless network,which facilitates humans life. This paper proposes a design of kitchen appliance server to compensate for the lack in this field. The smart server for kitchen appliances is based on OpenWrt (an open source embedded system). Via the transformation of TP-Link Wr703n router and extracting associated control port,the compiled OpenWrt system can be migrated to the router. Smart phones can connect with the router via WiFi networks,and they all constitute the smart server network. The smart kitchen appliances server and microwave can establish a connection,and the reliability and practicality of the smart server have been verified.
