However, in the process of expanding intelligent lighting products, consumers and suppliers find that the current intelligent device module cannot meet the scene mode of the existing random application by adopting a traditional fixed IP address allocation mode, and particularly, products depending on internet address allocation cannot be normally used completely when no external network exists, so that a self-adaptive local area network address allocation technology which can be suitable for the internet and the local area network is developed, the intelligent terminal device required by the consumer for randomly networking control at any time and any place is met, and the intelligent terminal device is certainly popular and loved in the market. The internet address allocation technology is a unique number for a terminal device to access or control other networks, thereby causing the disadvantages of small quantity or fixed address in the current address allocation control. This is not a problem for large network servers. But the method can become a fatal restriction to various terminal application devices in the internet of things. Because for a location in a non-network environment, once the external network is lost, the whole local area network cannot be networked for communication. Currently, the commonly used network IP address allocation employs dynamic IP and MAC binding assignment.
The existing LED lamp self-adaptive local area network address allocation technology cannot automatically realize networking and intercommunication without an external network, is particularly obvious when conventional wireless communication is adopted, and has the condition of insufficient IP addresses when more terminal control devices are adopted.
