Remote upgrade method and remote upgrade device for wireless sensor network node

Abstract

The invention relates to a remote upgrade method and a remote upgrade device for a wireless sensor network node and belongs to the technical field of communication, computers and Internet of things. Hardware of the device includes a network controller and a wireless sensor network node; software of the device includes three parts, namely upper computer software, network controller driving software and node driving software; an upper computer software interface is used for displaying all remote online wireless sensor network nodes, supporting for manually loading APP files of the nodes to an upper computer, supporting selecting to-be-upgraded nodes, sending instant to-be-started APP file fragments, and waiting for automatic remote upgrade completion of the nodes; during a data sending process, a multiple-check and resending mechanism is adopted, so as to ensure that the APP files are accurately sent to target nodes; and when special situations such as power failure occur to a node upgrade process, automatic re-upgrade is performed after restart, and finally self firmware update is completed. The remote upgrade method and the remote upgrade device are capable of solving the problem that the technology of the Internet of things is vigorously developed and wireless sensor nodes are widely applied, but upgrade is difficult, and saving manpower and financial resources, thereby being beneficial to promotion of development of the industry of the Internet of things.

Description

technical field [0001] The invention belongs to the technical fields of communication, computer and Internet of Things, and relates to a method and a device for remotely upgrading wireless sensor network nodes. Background technique [0002] The Internet of Things is another revolutionary development of the information industry after computers, the Internet, and mobile communication networks. Its value lies in allowing objects to have "intelligence" and realizing communication between people and things, and between things. It has the characteristics of strong permeability, great driving effect and good comprehensive benefits. Promoting the development and application of the Internet of Things is conducive to promoting the transformation of production, life, and social management methods to intelligent, refined, and networked directions. The development of related disciplines and the enhancement of technological innovation capabilities are of great significance to promote ind...

Problems solved by technology

[0007] In view of this, the purpose of the present invention is to aim at the rapid development of the Internet of Things industry, the Internet of Things technology is widely used in various fields of life such as home furnishing, transportation, medical care, environment, industry, etc., but it is difficult to update the program of a large number of wireless sensor network nodes at the bottom of the Internet of Things In the context of the background, a low-cost, easy-to-operate remote upgrade method for wireless sensor network nodes is proposed. This method overcomes the shortcomings of the traditional local download upgrade method, that is, technicians need to use PCs to connect nodes with cables and use professional The host computer software downloads the new program, and sends the new firmware of the node on the remote host to complete the firmware upgrade of the node
