Internet of things control method and a system

Abstract

The invention provides an Internet of things control method and a system. The method comprises the following steps: a device end subscribes to a topic and sends configuration information of the topicto a server, the server receives and stores the configuration information, when the client end wants to change the configuration of the topic subscribed by the device end, the client end sends a control instruction to the device end; the device end changes its configuration according to the control instruction and sends the changed configuration to the server, the server updates the stored configuration information according to the changed configuration. The device end of the invention stores the configuration information in the server, so as to avoid that the memory of the device end with small memory is easily exhausted or the request is blocked due to the limited processor resources.

Description

technical field [0001] The invention relates to the field of the Internet of Things, in particular to an Internet of Things control method and system. Background technique [0002] The Internet of Things is an important part of the new generation of information technology, and it is also an important stage of development in the "informationization" era. As the name suggests, the Internet of Things is the Internet of things connected. This has two meanings: first, the core and foundation of the Internet of Things is still the Internet, which is an extended and expanded network based on the Internet; Exchange and communication, that is, things are closely related. The Internet of Things is widely used in the integration of networks through communication perception technologies such as intelligent perception, identification technology and pervasive computing. The Internet of Things has a wide range of uses, covering intelligent transportation, environmental protection, gover...

AI Technical Summary

Problems solved by technology

However, if the configuration information of the device is stored on the device itself, and all operations are performed between the device and the client, the following problems may occur: 1) The IoT device generally has a small memory and limited processor resources. Multiple clients requesting device information multiple times can easily consume device memory or cause request blocking

2) The network environment where the IoT device is located is complex. In a cellular network or home broadband environment, packet loss is prone to occur, resulting in poor client experience

3) The IoT device itself is unstable, and it is easy to lose the configuration of the device due to power failure or other reasons, and it cannot be retrieved or it is difficult to retrieve the original configuration
