Description
Technical Field
The invention relates to the technical field of Internet of things connection, in particular to a method for mutual configuration of Internet of things devices.
Background
WIFI is also called wireless network, is a trademark of WIFI alliance, a wireless local area network technology based on IEEE802.11 standard. The IEEE802.11 standard defines a Medium Access Control (MAC) layer and several physical layer (PHY) specifications to provide wireless connectivity for fixed, portable and mobile terminals within a local area network.
At present, the internet of things equipment needs to configure a network by inputting a password, so that the internet or a server can be accessed to realize the functions of the internet of things equipment. The operation of configuring the network is troublesome, and as more and more devices of the internet of things are used, or in a scene requiring batch deployment, each device needs the same operation to access the network, which brings inconvenience to users. For the internet of things equipment without an input interface, the configuration of the network is more inconvenient. The method for configuring the WIFI account for the Internet of things equipment without the input interface in the prior art mainly comprises three methods, namely the Internet of things equipment is provided with an Ethernet interface, the Internet of things equipment is accessed to the Internet by using a network cable, WIFI account information is transmitted to the equipment through a cloud server, and the network cable is unplugged after the Internet of things equipment receives the WIFI account, so that WIFI is connected; secondly, a WIFI hotspot of a fixed SSID (Service Set Identifier) is started on the Internet of things equipment, the user switches the WIFI of the mobile terminal to be connected to the Internet of things equipment, and the WIFI account information is transmitted to the Internet of things equipment through application software on the mobile terminal. And thirdly, a monitoring mode is started through a WIFI module of the Internet of things device to receive WiFi parameters broadcasted by terminal devices such as the mobile terminal.
In the third scheme, a common solution is to fill the header part of the MAC layer packet with information to be transmitted to the internet of things device by using the signal of WIFI itself. The Internet of things equipment is started to enter a scanning mode, whether supported data exist in each channel needs to be monitored, and if the supported data exist, the data are analyzed to configure the Internet of things equipment.
The above scheme has the following problems: (1) the technology generally only encodes data for transmission without encryption because of less available space of the packet head part of the MAC layer data packet, so that a third party can illegally acquire transmitted information by monitoring and analyzing; (2) the transmission capacity is small, and the technology divides and fills data to be transmitted into the header part of the MAC layer data packet, and transmits the data for multiple times, so that transmission failure is easily caused by packet loss if the transmitted data volume is large, and the technology is limited to be only applied to transmitting a small amount of data; (3) when the deployment is carried out, special mobile terminal equipment and other equipment are required to be used for broadcasting, and the mass deployment is inconvenient.
