Remote upgrade function realization method and system based on MCU and TFTP protocol

Abstract

The invention discloses a remote upgrade function implementation method based on an MCU and a TFTP protocol. The method comprises the steps that application software of special equipment of a local upgrade management system establishes TCP network connection and sends a software version query message to the special equipment; the special equipment obtains software version information and reports the software version information to the local upgrading management center to judge whether upgrading is executed or not; if so, a to-be-upgraded software version of the local upgrade management receiving system sends a software deployment instruction to the special equipment; the special equipment confirms whether a software deployment process is executed or not to the local upgrade management; the special equipment applies for file downloading from the local upgrade management center according to the upgrade package downloading path, verifies upgrade package data, and reports file downloading success or downloading failure; and after the upgrade package is successfully downloaded, the special equipment executes the deployment upgrade work of the equipment software. According to the invention, remote operation of upgrading is realized through rapid upgrading management of special equipment for ground stations at different deployment sites, and the operation and maintenance cost of the ground receiving system is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellite equipment, in particular to a method for realizing a remote upgrade function based on an MCU and a TFTP protocol. Background technique [0002] The remote sensing satellite ground receiving system has the ability to receive remote sensing satellite data and plays an important role in the wide application of remote sensing satellite data. With the gradual increase in the number of launched remote sensing satellites, the construction and deployment of remote sensing satellite ground receiving systems are also increasing. The geographical distribution is becoming more and more extensive, so the operation and maintenance work of the ground receiving system is becoming more and more difficult. [0003] In order to improve the operation and maintenance efficiency of the ground receiving system and realize the operation and maintenance of the automatic system, the ground receiving system...

AI Technical Summary

Problems solved by technology

There may be equipment abnormalities in the remote sensing satellite ground receiving system. To upgrade the equipment, most of the previous upgrade methods used special equipment and special tools. It is not convenient to open the box to upgrade the equipment to be upgraded on site, but also reduces the efficiency.
