| With the development of modern information technologies,people have more demand of the intelligent level of daily electrical devices in their family.Recently,in result of the computer network and the communicate technology are widely used,daily electrical devices are more advanced and intelligent.But the lack of specifications leads to amount of devices’ type,and the difference of interfaces between those devices,which makes the management of devices in normal household much more complicated.This thesis designs a route software system based on OpenWRT named OWIG which is both an intelligent network guarantee and manager of household devices.We describe residential gateway’s implement situation in current intelligent home solutions,then describe present related work of remote-upgrade technology.We analyse the business circuit,the function and performance requirement of OWIG,based on these,we proposed architecture and the modules division of OWIG.The OWIG system is divided into communication sub-system and management sub-system.The communication sub-system accomplishes communicating between OWIG and users or Internet which is divided into user-interaction module,app-services module,remote-upgrade module.Thus family user can set the network limits to other authorized users.This thesis propose prominently the detail design of secure-connection between CPE and ACS,which can remote-upgrade system through this connection.Meanwhile users can interact with system by Lua scripts or CGI scripts.The management sub-system accomplishes the management of devices and data in OWIG,monitor and manage household devices,which more store personal or sharing documents and it is divided into three modules which are user-management,device-management and file-management.We use TC and iptables technology to monitor and configure the network flow for users,providing convenient intelligent household environment.After all work above,This thesis evaluate OWIG system by running a series of practicability and functionality tests.We design Black box test toward configuration of VLAN and all modules,and White box test to verify the performance of our system.The result demonstrates that OWIG system conforms to the prediction. |
