Abstract

The invention provides a general USB (Universal Serial Bus) based equipment firmware updating method. The method comprises the following steps of: (1) providing a control computer and intelligent equipment; (2) electrically connecting the intelligent equipment with the control computer by utilizing a USB through a USB interface; (3) running a firmware upgrading program upper computer by the control computer and providing a man-machine friendly guide type updating operation and display interface for a user; (4) running a firmware updating program lower computer by the intelligent equipment; (5) sending an operation command of the user to the firmware updating program lower computer by the firmware updating program upper computer to control the intelligent equipment to switch to a firmware updating mode; (6) acquiring a new edition firmware program by the firmware updating program and downloading the new edition program into the firmware updating program lower computer by blocks; and (7) acquiring all blocked programs by the firmware updating program lower computer, then combining, splicing and checking, and prompting the user whether the firmware updating is successful or not. The invention sufficiently utilizes the traditional standard USB interface of the computer and helps the user to finish a firmware updating task with high efficiency.

Description

technical field [0001] The invention relates to a device firmware upgrade technology, in particular to a device firmware upgrade method based on a general usb bus. Background technique [0002] With the rapid development of electronic technology, all walks of life can see more and more in-depth applications of intelligent detection and testing equipment. These smart devices have a common feature, which is provided with a program read-only memory inside, and a control program for making the smart device play an intelligent control function is stored in the memory. The program in the read-only memory is read-only and cannot be modified during the normal operation of the device, as if it is a fixed object, so it is called firmware. Due to changes in functional requirements of smart devices, or defects in firmware programs that need to be repaired, it is necessary to develop a new method that can update and upgrade device firmware programs. [0003] The most commonly used meth...
