Internet of Things system based on UPNP protocol, and Internet of Things system data transmission method based on UPNP protocol

Abstract

The invention discloses an Internet of Things system based on a UPNP protocol, and an Internet of Things system data transmission method based on a UPNP protocol. The Internet of Things system comprises a source device supporting the UPNP protocol and a target device supporting the UPNP protocol, also includes a man-machine interaction module in the source device, wherein when the source device searches the address, the man-machine interaction module sends the response information to the source device according to the acquired service information of the target device. The Internet of Things system based on a UPNP protocol, and the Internet of Things system data transmission method based on a UPNP protocol can realize zero-failure for the connection between the source device and the target device, and can realize free transmission of data between the source device and the target device on different platforms, and can be quick and efficient in transmission, and can be simple in secondary development and access, and can reduce the threshold for data flowing for different platforms.

Description

technical field [0001] The present invention particularly relates to an Internet of Things system and an Internet of Things data transmission method based on the UPNP protocol. Background technique [0002] The UPNP protocol is the Universal Plug and Play protocol. At present, the IoT system based on the UPNP protocol can realize the following functions: [0003] 1. Automatically realize mutual discovery and automatic connection between devices in the LAN. [0004] 2. After the devices are connected to each other in the local area network, you can put the video of device A to device B for playback, and control the video play / pause, volume increase and decrease, and playback progress control of device B on device A. [0005] 3. After the devices are interconnected, the multimedia resources of device B can be accessed on device A. [0006] Due to differences in the hardware generated by different device manufacturers and the implemented software protocol stacks, in some cas...

AI Technical Summary

Problems solved by technology

[0006] Due to differences in the hardware and software protocol stacks generated by different device manufacturers, in some cases, the existing UPNP protocol-based IoT system devices cannot discover each other and automatically connect

At the same time, the existing UPNP protocol-based IoT system devices can only communicate with each other, and cannot realize the free copy transmission of data, especially the efficient transmission of big data
