Terminal device firmware upgrading method and system based on Websocket long connection

Abstract

The invention discloses a terminal device firmware upgrading method and system based on Websocket long connection. The method comprises the steps that a terminal device builds a Websocket long connection with a server after the terminal device is networked, wherein the server stores a first firmware installation package and a first download address, a first firmware identifier and a first firmwareversion, which are corresponding to the first firmware installation package, and wherein the terminal device stores a second firmware identifier and a second firmware version corresponding to a currently-used second firmware installation package; and based on the Websocket long connection, the terminal device obtains the first download address from the server and downloads the first firmware installation package for upgrading according to the first download address. The terminal device firmware upgrading method and system based on Websocket long connection are good in user experience and convenient to operate. On the one hand, the terminal device can actively send an upgrading request; on the other hand, the server can actively issue an upgrading instruction.

Description

technical field [0001] The invention relates to the technical field of terminal device firmware upgrade, in particular to a method and system for upgrading terminal device firmware based on Websocket long connection. Background technique [0002] Firmware is a program written in EROM (Erasable and Programmable Read-Only Memory) or EEPROM (Electrically Erasable and Programmable Read-Only Memory), which refers to the device "driver" stored inside the device, such as CD-ROM drive, recorder, etc. Internal firmware, the operating system can realize the operation of a specific machine according to the standard device driver through the firmware. [0003] At present, in the fields of security, attendance, witnesses, video, etc., most of the firmware upgrades of terminal devices are still manually upgraded. Go to the terminal device to perform the upgrade operation, or copy it through a remote connection, and then go to the terminal device to perform the upgrade operation. The ent...

AI Technical Summary

Problems solved by technology

The entire firmware upgrade process is cumbersome, consumes a lot of human resources, the operation is not convenient enough, and the user experience is poor

[0004] The existing solutions for automatically upgrading the firmware installation package through the cloud platform server have the following problems: 1. The server and the terminal device need to be connected through a middleware device, which increases the hardware cost on the one hand, and on the other hand, the server and the terminal device The device cannot directly exchange messages, which leads to easy loss of messages and increased security risks; 2. The terminal device can only initiate an upgrade request to the server or / middleware device to the server, and the server cannot initiate an upgrade command to the IoT terminal. On the one hand, it cannot Realize batch upgrade instructions. On the other hand, if the firmware installation currently used by the terminal device is defective, the server cannot actively issue the upgrade command in time, and can only wait for the upgrade request message of the terminal device, which is not time-sensitive.
