Problems solved by technology

[0004] However, existing computer industrial control equipment and embedded equipment generally require manual operation of mouse and keyboard equipment to control the software upgrade process, and the software upgrade is not convenient and flexible enough.
And for a terminal with only a touch screen but no keyboard and no mouse, it will be difficult and inconvenient to upgrade the software and firmware in the initial stage of embedded startup, especially if there is no touch screen driver support.

Abstract

The embodiment of the invention discloses a software upgrading method and a software upgrading device, which are used for upgrading a software. The method disclosed by the embodiment of the invention comprises the following steps: acquiring the current state value of a dial switch connected with a master controller after the master controller is electrified; determining whether upgrading is carried out on the software according to the state value; and if upgrading on the software is needed, carrying out the upgrading operation on the software. With the adoption of the software upgrading method and the software upgrading device, the master controller can be effectively and automatically triggered for upgrading operation without using a keyboard, a mouse, display equipment and other external devices to control software upgrading, and the software upgrading is more flexible.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a software upgrading method and device. Background technique [0002] Generally, general-purpose computer industrial control equipment and embedded devices are basically equipped with access devices such as serial port debugging, network port communication, keyboard and mouse, and display devices. At present, software upgrades on computer industrial control equipment and embedded terminal devices are basically controlled through serial ports. , network remote online upgrade, etc., use external input and output devices such as keyboards, mice, display devices, etc. to control the software upgrade process. Specifically: the industrial control equipment and the embedded terminal target equipment are connected to the serial port or network card of the computer system through a serial port cable or a network cable, and the operator operates the keyboard and mouse and other equipment...
