Abstract
The invention provides a network camera system online update method. Five subareas are employed. The subareas comprise a Boot subarea, a kernel subarea, a Ramdisk Rootfs subarea, a Ubifs App subarea and a Ubifs Config subarea. Moreover, a whole update process is divided into three parts. A first part comprises signal interaction. A second part comprises mirror downloading and application replacement. The second part can be divided into kernel update, file system update and application update. A third part comprises device reboot and update edition confirmation. According to the method, the waste of hardware storage resources resulting from a network camera update mechanism is reduced; the hardware cost is reduced; the problem that a system cannot be booted due to accidental power failure in an online update process of a network camera device can be solved. The interaction in the network camera update process is increased. The update progress is accurately tracked.
Description
Technical field
The invention belongs to web camera technical field, be specifically related to a kind of internet protocol camera system online upgrading method.
Background technology
Along with developing rapidly of network, digital security monitoring development is advanced by leaps and bounds, and increasing web camera starts to replace
Change traditional analog video camera and become the main flow of safety monitoring.Web camera can be installed to the whole world Anywhere, passes through
The long-range preview of monitoring software, the multiformity of the demand that extensively introduces of use, the remote maintenance upgrading of video camera also seems to pass
Important.
Industry Normal practice is employing system double copies mechanism at present, and system partitioning is illustrated such as Fig. 1.System uses four points
District, is boot partition Boot respectively, kernel subregion kernel, and host file system subregion A uses Ubifs form,
Backup file partition B uses Ubifs form.
Fig. 2 is upgrading tool and the internal interaction diagrams of video camera in escalation process.Whole escalation process is divided into two parts,
Part I signals, Part II image download and self renewal.Upgrading Fig. 3 describes firmware and downloads in video camera
Portion, video camera self renewal schematic diagram.
Detailed process is shown in Fig. 4, it is described as follows:
The first step: upgrading tool builds WEB server, creates Client simultaneously.
Second step: web camera starts upgrading, and the Client of upgrading tool actively connects the liter within web camera
Level service Server.
3rd step: after upgrading tool Client connects the upgrading Server success within web camera, send network and take the photograph
Camera upgrade command.
4th step: after the upgrading Server within web camera receives upgrade command, web camera enables automatically
Wget downloads firmware updating.
5th step: the firmware of web camera has been downloaded, the firmware size that verification is downloaded is the most correct.
6th step: firmware updating inspection OK, web camera upgrade service starts to automatically update replacement backup partition content.
7th step: web camera backup subregion has updated, carry backup subregion, will be current to internet protocol camera system
The configuration file of main system copies backup subregion to.
8th step: the configuration file of internet protocol camera system updates replacement to be completed, and revises system start-up subregion sign, by standby
Part subregion loads as main partition, by current main partition as backup subregion.
9th step: system start-up mark has updated, occurs to notify that client, device upgrade complete, system weighs automatically
Open.
Tenth step: web camera is restarted successfully, upgrading tool actively connects web camera, and detection version is the most successful.
But this way has following defects that the wasting of resources, whole file system backup, memory space money can be increased
Source.Such as: host file system size 60M, standby system is also required to the space resources of 60M, and only backs up subregion
For upgrading, it is not use this space under normal operation, greatly adds hardware cost.
Escalation process cannot be avoided to interrupt conductance cause to upgrade unsuccessfully, the serious system that causes cannot start.Whole escalation process
It is divided into three phases, updates backup zone time T1, more new configuration file time T2, revise active flag time T3.
Occurring that accident power-off can cause upgrading unsuccessfully in T1 and the T2 stage, after power-off, system can be again started up, if at T3
Stage occurs that accident power-off, situation there will be severe system and cannot start.Power-off occur in any stage, being all cannot
Avoid, all can cause upgrading unsuccessfully.This is also the critical defect of the program.
Escalation process does not have information mutual, it is impossible to be accurately positioned escalation process, especially after download firmware to video camera,
Operated by be all to complete inside video camera, externally do not have any alternately, it has not been convenient to track and localization upgrading progress.
Summary of the invention
It is an object of the invention to provide a kind of internet protocol camera system online upgrading method, reduce web camera upgrade mechanism
The hardware store wasting of resources caused, saves hardware cost.Solve accident during web cam device online upgrading
Power-off causes the system cannot starting problem.Increase web camera escalation process mutual, accurately follow the tracks of upgrading progress.
The invention provides following technical scheme:
A kind of internet protocol camera system online upgrading method, takes five subregions, is boot partition Boot respectively, and kernel divides
District kernel, root file system district Ramdisk Rootfs, application partition Ubifs App, and configuration file subregion
Ubifs Config；
Meanwhile, whole escalation process is divided into three parts, and Part I is Signalling exchange；Part II be image download and
Program is replaced, and this part can be divided into the upgrading of kernel upgrading, file system and application program updating；Part III is
Equipment is restarted and is confirmed with upgraded version.
Specifically include following steps:
S1, upgrading tool create Tcp Client, send upgrade information xml message to web camera, web camera
TCP Server receives this xml message；
The packet parsing that S2, web camera receive, the platform information of response upgrading tool equipment self and version information；
S3, upgrading tool are according to the platform information received and version information, and packing currently prepares the version information of upgrading,
Again web camera is issued；
S4, web camera resolve the version information that upgrading tool sends, it may be judged whether need upgrading, if the version of upgrading
This is newer than web camera version, returns firmware updating order, if the version of upgrading does not has radiography unit version new, stops
Upgrading；
S5, web camera receive instrument and the firmware information of coming occur, and start to update kernel, and renewal completes, and occur to rise
Level completion status；
S6, kernel upgrading complete, and start to download file system, and the state that sends is to upgrading tool；File system has been downloaded
Starting self renewal, the state that sends is to upgrading tool；
S7, repetition S6, download application program；Then self renewal；
After S8, kernel, file system, application program three part have updated, the state that sends, to upgrading tool, then sets
For starting to restart；
S9, web camera are restarted successfully, and upgrading tool actively connects web camera, and detection version is the most successful.
The invention has the beneficial effects as follows: save hardware resource, reduce product cost, add finished product competitiveness；Solve
Escalation process of having determined interrupt the equipment that causes cannot starting problem, facilitate product maintenance, saved what product up-gradation produced
Extra human cost resource；Escalation process implements mutual monitoring, facilitates operator to position upgrading progress, improves efficiency.
