Method for updating embedded system software

Abstract

The invention discloses a method for updating embedded system software. The software comprises a master station / server and equipment. The method comprises the following steps that: A, the master station / server extracts configuration information and an equipment linked list, sets an upgrading network, opens a log and starts an upgrading process; B, an upgrading module receives an upgrading file from the master station / server and updates upgrading process information to a nonvolatile region in real time; C, the upgrading file is verified, stored and filed and running switching data is set; D, main and auxiliary running regions are switched, test run of a new edition program is performed, running is performed if the test run is abnormal, and if the test run is abnormal, a state code is reported, the main and auxiliary running regions are switched and the program of a previous normal running edition is run; and E, the equipment generates a local log and the master station / server stores an upgrading log.

Description

technical field [0001] The invention relates to an embedded system software upgrading method. Background technique [0002] With the advancement of science and technology and the development of technology, the intelligent components of embedded devices are getting higher and higher, and the requirements for equipment are becoming more and more specific, and the update cycle of requirements is becoming shorter and shorter, even in the life cycle of equipment. Internally, there is a need for function expansion or upgrade. The distribution of embedded devices is generally scattered (such as terminal products), and some products are even relatively remote. If they are upgraded or updated manually on site, it will consume a lot of manpower and construction period. [0003] With the development of wireless communication network technology, the speed and reliability of wireless communication itself are getting higher and higher, so some technologies or methods attached to wireless...

AI Technical Summary

Problems solved by technology

[0004] 1: During the upgrade process, it will affect the current operation function of the device, and seriously cause some real-time data errors

[0005] 2: During the upgrade process, if the device is abnormal (such as reset, crash, etc.) or the operating environment of the device is abnormal (power failure, strong electromagnetic interference, etc.), the device will be completely paralyzed and must be repaired or replaced manually on site.

[0006] 3: After the upgrade is completed, if there is an abnormality in the program (such as incomplete upgrade files, errors or even frequent resets, etc.), the device cannot locally restore the normal running program of the previous version, and it cannot inform the server of the exact status of the device

Can only manually check the status of the equipment on site and repair or replace it

[0007] 4: The upgrade file and the system file are not independent, which is not conducive to the local file management and version management of the device
