Detailed Description
The invention provides a multi-interface integrated software upgrading method, which can not only solve the technical problems, but also complete the self-upgrading of an upgrading system on line.
The invention integrates the serial port, USB and WiFi three-channel upgrading method, and when the embedded software system of the equipment only has a serial port, the software system is automatically switched to serial port communication. When the embedded system of the equipment has a serial port and a USB, the software system is firstly switched to USB communication. When the embedded system of the equipment has a serial port, USB and WiFi, the software system is firstly switched to USB communication, and when the USB does not access the equipment, the software system is switched to a WiFi wireless channel. The user can also configure the transport port that is opened first and switch to the next communication port without opening the default communication port. The system is an operating system which can run in a self-adaptive mode, and a plurality of versions do not need to be compiled. The system automatically switches to a WinCE system or a Windows desktop system or a Linux system to run by identifying the running operating system.
The system is separated from the embedded software to be upgraded and is stored in one position with the embedded software to be upgraded. The embedded software to be upgraded calls the system software, and the system software can also run independently. The system software has information security processing, and enters an upgrade page by inputting a password when needing to be upgraded. The system provides the software upgrading function of the upper computer software and the lower computer software and the transparent transmission upgrading of other sub-modules of the lower computer. The system and the lower computer software carry out RS232 serial port communication.
The software interface of the system is divided into three parts, wherein the upper part displays the upgrading step, and the currently-performed step can be displayed in different colors. The middle part displays an upgrading module list, the name of the module to be upgraded, the currently running software version number and the version number needing upgrading, a progress bar and an individual upgrading button. Two operation buttons are displayed on the lower portion of the interface. When the software runs in the Windows desktop system environment, the interface can display the serial port number selection box. The serial port 1 is configured by default, and a user can select the serial port number of the connected equipment. The system automatically switches interface language information by identifying the equipment language. Support 10 languages: chinese, english, spanish, russian, czech, polish, italian, french, romania and portuguese.
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and examples.
