Internet of Things device remote control method and system

Abstract

The invention provides an Internet of Things device remote control method and system. The method comprises the following steps: a terminal device without the fixed IP address sending a pipeline connection request for establishing an SSH pipeline with a server to the server with the fixed IP address based on an SSH protocol; enabling the server to establish a connection port used for communicatingwith the terminal device and a monitoring port used for monitoring the remote control equipment to remotely control the terminal device in the server according to the pipeline connection request; andthe terminal device receiving the remote control command sent by the server through the connection port, and controlling the Internet of Things equipment connected to the terminal device according tothe remote control command. According to the method and the system, the terminal device without the fixed IP address and the remote control equipment without the fixed IP address establish the SSH connection through the server with the fixed IP address. Therefore, the problem that the Internet of Things equipment is remotely controlled under the big background that the public network address is not enough and the number of the Internet of Things terminal device is continuously increased at present is solved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Things control, in particular to a remote control method and system for Internet of Things devices. Background technique [0002] A large number of IoT devices such as sensors and cameras are emerging, but the IP addresses that can be used by the devices are very limited. The currently popular IPv4 provides very limited IP addresses. There are 4.3 billion IP addresses in the world, which has basically been exhausted. In order to solve the problem of lack of IP addresses, it was proposed by IETF in the 1990s to solve the problem of limited IPv4 addresses. This protocol has 7.9×10^28 IP addresses to choose from, which can well solve the problem that the current IP is not enough. question. However, IPv6 will also face security and popularization issues. At present, most (about 90%) IP addresses on the Internet are still based on IPv4, and many IoT terminal devices cannot implement IPv6 d...
