Camera remote firmware upgrading system and method based on GigE Vision interface

Abstract

The invention provides a camera remote firmware upgrading system and method based on a GigE Vision interface. The method comprises the following steps: a firmware upgrading package which is compressed based on Huffman coding and at least comprises two files is provided, wherein one is a configuration file, and the other is a to-be-upgraded file; the firmware upgrading package is stored in a directory of a server; a camera is connected with an upper computer PC, the camera enters a GVCP feedback command thread, and the upper computer initializes the camera and then sends a command data package of firmware upgrading to the camera through a GVCP protocol; after the camera returns a confirmed ACK data package to the upper computer, the upper computer obtains the firmware upgrade package from the server and then sends the firmware upgrade package to the camera; the camera receives the firmware upgrade package sent by the upper computer; the firmware upgrade package is uncompressed based on Huffman coding, and finally, the firmware upgrade package is written into a specified directory.

Description

technical field [0001] The invention relates to the field of firmware upgrading, in particular to a camera remote firmware upgrading system and method based on the GigE Vision interface. Background technique [0002] To upgrade the firmware of existing devices, you need to replace the files in the flash with a card reader, connect the host computer and the development board through a cable to replace the files in the flash, or use an FTP tool to replace the files in the flash. Frequent plugging and unplugging of the sd card requires powering off the device during the process, and re-powering on after the upgrade, which is relatively complicated; the camera will cancel the use of the sd card in the future, and use QSPI+eMMC flash storage media. It is very inconvenient to upgrade by connecting the host computer and the development board through a large number of cables; to upgrade through FTP tools requires the use of third-party tools, and the IP address of the camera must be...

[0002] To upgrade the firmware of existing devices, you need to replace the files in the flash with a card reader, connect the host computer and the development board through a cable to replace the files in the flash, or use an FTP tool to replace the files in the flash. Frequent plugging and unplugging of the sd card requires powering off the device during the process, and re-powering on after the upgrade, which is relatively complicated; the camera will cancel the use of the sd card in the future, and use the flash storage medium of QSPI+eMMC, and use the onboard It is very inconvenient to upgrade by connecting the host computer and the development board through a large number of cables; upgrading through FTP tools requires the use of third-party tools, and the IP address of the camera must be confirmed in advance

The firmware upgrade of the device through the above three methods will greatly reduce the efficiency of the upgrade, and cannot provide users with a good user experience.
