Description
Technical Field
The invention relates to the technical field of remote upgrading of embedded equipment, in particular to a power-off self-recovery mechanism for remote upgrading of a network camera.
Background
In daily life, the network camera is visible everywhere and acts as a recorder of traffic violation; defenders playing campus and family protection; the invention aims to solve the problem that network camera equipment cannot work normally due to abnormal conditions such as sudden power failure and the like in the remote upgrading process of a network camera.
Disclosure of Invention
The invention aims to provide a power-off self-recovery mechanism for remote upgrade of a network camera, which aims to solve the problem that network camera equipment cannot work normally due to abnormal conditions such as sudden power-off and the like in the remote upgrade process of the network camera, which is provided in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme: a network camera remote upgrading power failure self-recovery mechanism comprises the following steps; s1, starting upgrading; s2, storing url of the remote server upgrading firmware; s3, downloading the new firmware to the memory and saving an upgrade flag file; s4, erasing and writing; s5, judging whether power failure occurs in the upgrading process; s6, erasing is completed; s7, deleting the upgrading mark file; s8, restarting the equipment; and S9, normal operation of the equipment.
Preferably, before burning a new upgrade firmware into a ROM storage medium of the device, the device first saves a url file recording a download link of the remote upgrade firmware in the system partition.
Preferably, a new firmware program is downloaded to the RAM according to the url, and an upgraded mark file is recorded, wherein the mark file exists and is mainly used for detecting the completion degree of the burning work, and the mark file can be deleted after the burning work is completed; not completed, the file will be retained.
Preferably, the firmware burning operation is started, the firmware program in the RAM is burned into the ROM, if no abnormal condition occurs, the execution continues to S6, and when abnormal conditions such as power failure occur, the device is jumped to and powered on again.
Preferably, no abnormal condition occurs, and after the burning is finished, the equipment deletes the mark file and restarts the equipment.
Preferably, the device is powered on again when abnormal conditions such as power failure occur, the device detects the upgraded logo file, and if the file is detected, the process goes to S3; if the file is not detected, it indicates that the burning work is completed before the abnormal condition occurs, and the process continues to execute S9.
The invention has the beneficial effects that: the invention can solve the abnormal conditions such as sudden power failure and the like in the remote upgrading process without adopting a ROM backup mechanism under the condition of limited ROM storage space, the network camera can automatically recover to work, the problem of crash in the remote upgrading process of the network camera can be reliably solved, the maintenance cost of hardware and personnel of embedded equipment is saved, and the user experience is improved.
Drawings
FIG. 1 is a flow chart of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1, please refer to fig. 1, the present invention provides a technical solution: a network camera remote upgrading power failure self-recovery mechanism comprises the following steps;
firstly, before burning new upgrade firmware to a ROM storage medium of equipment, the equipment stores a url file for recording a download link of the remote upgrade firmware in a system partition;
step two, downloading a new firmware program to an RAM according to url, and simultaneously recording an upgraded mark file, wherein the mark file exists and is mainly used for detecting the completion degree of the burning work, and the mark file can be deleted after the burning work is completed; not completed, the file will be retained;
step three, starting firmware burning work, burning a firmware program in the RAM into the ROM, and if no abnormal condition occurs, continuing to execute the step four; jumping to the fifth step when abnormal conditions such as power failure occur;
step four, no abnormal condition occurs, after the burning is finished, the equipment deletes the mark file, the equipment is restarted, and the step six is skipped;
step five, when abnormal conditions such as power failure occur, the equipment is electrified again, the equipment can detect the upgraded mark file, and if the file is detected, the step two is skipped; if the file is not detected, before the abnormal condition is shown, the burning work is finished, and the step six is continuously executed;
and step six, successfully upgrading, and enabling the equipment to normally work.
During the remote upgrade of the network camera, the download link of the upgrade firmware of the remote server can be stored, when the abnormal phenomenon of power failure occurs, the network camera marks the abnormal emergency, when the network is electrified again, the abnormality of the original upgrade process can be detected, at the moment, a backup ROM storage mechanism is not needed, the network camera can request the remote server to continuously download the upgrade firmware, and after the download installation action is executed, the network camera can work normally again.
All the electrical components in the present application are connected with the power supply adapted to the electrical components through the wires, and an appropriate controller should be selected according to actual conditions to meet the control requirements, and specific connection and control sequences should be obtained.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
