Problems solved by technology
However, since the LAN using UDP protocol communication has not established a connection, it is difficult to determine the number of connected clients
Moreover, when a client changes the status of the smart device, it cannot be guaranteed that all clients on the LAN can obtain the latest status of the smart device synchronously

Embodiment Construction
[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0036] The invention provides a communication method of an intelligent device.
[0037] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the communication method of the smart device of the present invention;
[0038] In this embodiment, the communication method of the smart device includes:
[0039] Step S10, after successfully connecting to the network, send the device information to the client through broadcast and / or multicast, wherein the device information includes at least an IP address, port number, identifier and status serial number;
[0040] Specifically, the smart device is connected to a power source, and connected to the network according to the saved network information. If the smart device is used for the first time, the smart device is configured to access the tar...

The invention discloses a communication method and device for intelligent equipment. After the intelligent equipment is connected with the network successfully, equipment information is sent to a client through broadcast and / or multicast, and the equipment information at least comprises the IP address, the port number, the identifier and the state serial number; in dependence on the IP address, the port number, and the UDP, a control instruction emitted by the client is received, and the state is changed in dependence on the control instruction; when a state change is detected, the state serial number is updated to be the newest state serial number, and the newest state serial number is sent to the client through broadcast and / or multicast. Through the above way, resources occupied by the equipment are reduced, and the number of clients is not limited. When the state is updated, the state serial number of the equipment is increased, under the condition that the number of clients connected with the equipment is not known, that all clients in the local area network and the client can synchronously update the state is guaranteed, and the user experience is improved.
Description
technical field [0001] The invention relates to the field of the Internet of Things, in particular to a communication method and device for an intelligent device. Background technique [0002] With the popularity of the Internet of Things, various smart Internet of Things devices emerge in endlessly. In the home environment, smart IoT devices mainly use LAN for communication, and the commonly used LAN communication protocols for smart IoT devices include TCP protocol and UDP protocol. The TCP protocol is a connection-oriented protocol, which can ensure that the communication data reaches the receiver. However, using the TCP protocol for communication consumes a lot of resources, and the hardware resources of smart IoT devices are very limited. Therefore, when using the TCP protocol for communication, the number of client connections in the LAN will be limited. If the number of connected clients exceeds the specified number, it is necessary to restrict new incoming clients ...
