Apparatus for restoring network information for home network system and method thereof

Abstract

An apparatus for restoring network information for a home network system and a method thereof are disclosed. The apparatus includes at least one slave having means for communicating with an external appliances; a master having means for communicating with the slave, checking a state of the slave, storing state information of the slave, and providing the state information to the slave when the slave is reset; and a home network unit connecting the communication means of the master and the slave to form a network of the master and the slave.

AI Technical Summary

Benefits of technology

The present invention aims to solve the problem of lost network information in a home network system caused by power failures or abnormal operations of the network devices. The invention provides an apparatus for restoring network information, which includes a master device that communicates with the network devices and checks their state, stores the state information, and provides it to the devices when they are reset. Additionally, a home network unit is used to connect the master device and the network devices to form a network. The method of restoring network information involves periodically checking the state of network devices, storing their state information, and transmitting it when the devices are reset. Overall, the invention ensures the restoration of network information and enhances the reliability and stability of the home network system.

Problems solved by technology

Meanwhile, if an error occurs during the communication as shown in FIG. 2b after the master requested the command to the slaves, the slaves fail to respond to the master.

However, if slaves are reset due to an instantaneous power failure or any abnormal operation of the slaves and thus the slaves lose the operation-related network information, the slaves fail to remember their operation states before they are reset, and thus cannot perform their corresponding operations.

As described above, the conventional home network system has the drawbacks in that if the network information related to the operation of the slaves is lost due to an instantaneous power failure or an abnormal operation of the slaves, the user must reset the network information, and this causes inconvenience to the user.

Also, as the number of slaves increases, the time required for resetting the slaves also increases.
