Abstract:
1. An address allocation method for intelligent information appliances in a household network, the method comprising: (a), sending by an intelligent information appliance a broadcast message that carries the MAC address of the intelligent information appliance; (b), after the broadcast message is received by an adapter unit, storing by the adapter unit the MAC address of the intelligent information appliance, converting by the adapter unit the broadcast message into a computer bus signal that carries device connection information, and sending by the adapter unit the computer bus signal to a computer bus main processing module; (c), after the computer bus main processing module receives the computer bus signal, sending by the computer bus main processing module a computer bus signal containing an unused computer bus address to the adapter unit; (d), storing by the adapter unit the unused computer bus address, encapsulating by the adapter unit the computer bus signal that carries the unused computer bus address in a unicast message that carries the MAC address of the computer bus main processing module, and sending by the adapter unit the unicast message to the intelligent information appliance according to the previously stored MAC address of the intelligent information appliance; (e), after the intelligent information appliance receives the unicast message, analyzing by the intelligent information appliance the message to obtain the MAC address of the computer bus main processing module and the unused computer bus address, and storing by the intelligent information appliance the MAC address of the computer bus main processing module and the unused computer bus address, then returning by the intelligent information appliance an acknowledgment message to the adapter unit; (f), storing by the adapter unit the previously stored unused computer bus address and the MAC address of the intelligent information appliance into a mapping list used for recording the mapping relation between computer bus addresses and MAC addresses, then returning by the adapter unit a computer bus signal that carries an acknowledgment message to the computer bus main processing module; (g), after the computer bus main processing module receives the acknowledgment message, storing by the computer bus main processing module the unused computer bus address into a computer bus address list marked with a particular mark; and (h), dependent upon the mapping list, the intelligent information appliance functioning as an external device of the computer bus main processing module communicates with the computer bus main processing module by using a computer bus protocol.
