Abstract

The invention is suitable for the technical field of the network, and provides a searching method and searching system of local area network equipment. The searching method of the local area network equipment comprises the following steps: primary equipment acquiring a broadcast address of the located LAN when detecting a first preset instruction for searching slave equipment, wherein the primaryequipment sends an equipment searching request to the broadcast address of the LAN, thereby enabling the equipment searching request to be broadcasted in the local area network; the slave equipment returns slave equipment information to the primary equipment according to the equipment searching request, so that the searching step of the LAN equipment is simplified.

Description

technical field [0001] The invention belongs to the field of network technology, and in particular relates to a search method and a search system for local area network equipment. Background technique [0002] The existing Internet of Things network is based on Transmission Control Protocol (Transmission Control Protocol, TCP) or Internet Protocol (Internet Protocol, IP). To realize data transmission between smart devices, the IP address of the destination device must be obtained first, that is, Devices in the same LAN are searched. [0003] In the prior art, when searching for devices in the same local area network, it can be realized through existing local area network device discovery protocols, for example, multicast Domain Name System (multicast Domain Name System, mDNS) protocol and Universal Plug and Play (Universal Plug and Play, UPnP) protocol, however, the existing local area network device discovery protocol has a relatively complicated implementation process, is...
