Embodiment Construction

[0025] The specific process of the remote software update method proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] The realization of the scheme of the present invention is divided into two stages—that is, the U-boot customization before the deployment of sensor nodes and the software update stage after the deployment of the entire sensor network.

[0027] (1) Before each node is deployed, U-boot is customized and written into the memory of the node;

[0028] (2) After deployment, use the supporting development tool chain to compile and generate the software image file used for updating, send update instructions to each node of the sensor network through the background server, and update the software of the non-U-boot part on each node in turn, so that Realize the software update of the whole sensor network node.

[0029] Technical scheme of the present invention is specifically as follows:

Abstract

The invention relates to a remote software updating method, which comprises the following steps of downloading a software mirror image to target hardware in a remote communication mode in a target hardware and U-boot guide software environment to realize the non-U-boot part software upgrading on the target hardware which comprises an operating system and an application program part. According to the updating method, the updated software version record management and the node software updating state management of the same hardware configuration in the wireless network are realized in the uppercomputer software. By applying the method, the upgrading of the operating system and the application program of the target hardware node can be realized in a specific target hardware environment, themanual operation of the software upgrading of each hardware point is avoided, the workload of the development and maintenance personnel is effectively reduced, and the operation and maintenance cost is reduced.

Description

technical field [0001] The invention belongs to the fields of computer embedded software and the Internet of Things, and in particular relates to a method for remotely updating software on multi-node hardware of the Internet of Things based on U-boot. Background technique [0002] Software update means that when the software developer writes the software, because the designer does not consider comprehensively or the program function is not perfect, after the software is released, after the software is released, the program is modified or new functions are added, and the software is released again and deployed to the target system. the process of. [0003] U-boot, or UniversalBootLoader, is an open source system boot software. Developed from the open source project PPCBoot, ARMboot is incorporated into PPCBoot, and it is collectively called U-Boot with some other arch loaders. The first version U-Boot-0.2.0 was released on December 17, 2002. U-Boot provides two modes of op...
