Embodiment
Purpose of design of the present invention is: according to the middleware characteristic, the fusion mode of adaptive middleware and complete machine software, data management scheme with the mutual digital TV terminal middleware of operation platform is provided, guarantee that it can be stablized, operation safely, wherein, data management is meant operations such as software upgrading or data backup.In addition, in the scheme provided by the invention, the management process that has also comprised digital TV terminal complete machine software, if complete machine software needs upgrading, abide by the upgrade framework in the upgrading scheme, finish the realization of the corresponding interface, can realize the complete machine software upgrading, wherein, complete machine software is except the middleware, and other need the general name of upgrading software part in the terminal.
Middleware independence refers to, middleware only can obtain self residing store path, and have a control to this path, it is can arrange by oneself under this path deployment of self file of middleware, and except a cover graft layers interface, complete machine software and operating mechanism thereof are sightless fully for middleware.The middleware with independence stores by self and but operating mechanism guarantees stable operation and safety upgrade.When complete machine software and operating mechanism when open fully or part is open to middleware, middleware can be dissolved among the complete machine software, the non-independence of middleware this moment, and its upgrading then relies on the mechanism of complete machine software self to guarantee.
Upgrading scheme among the present invention, middleware independence and not merely different immediately upgrading modes have been taken into account, the adaptive middleware fusion form different with complete machine software, for the middle unit development person provides greater flexibility when being transplanted to new terminal, the middle unit development person can self role select the fusion form, and can be flexibly the position of intermediate member arranged in terminal storage equipment as required.
Referring to Fig. 1, the flow chart for the data managing method that the present invention is based on the digital TV terminal middleware comprises:
S101: the independence of judging the middleware of digital TV terminal;
S102:, then carry out data backup or software upgrading at middleware separately if middleware is independent;
S103: if middleware is not independent, then complete machine software is carried out in data backup or the software upgrade process, finish data backup or software upgrading simultaneously to middleware.
Differentiation process about independence is: when starting described digital TV terminal, read the middleware independence sign in the system parameters of digital TV terminal, thereby determine whether middleware is independent.For example, can judge by the value of system parameters root_path, be sky, then show not have independence, be not empty, then indicates the storage directory of middleware.
Preferably, further execution in step also after S102: call the interface between middleware and the Digital Television complete machine software, complete machine software is carried out data backup or software upgrading.Thereby mutual by middleware and operation platform, finish the upgrading of complete machine software.
As seen, the invention provides a kind of perfect data processing scheme based on middleware, this scheme fully takes into account the amalgamation mode of middleware and terminal platform software, amalgamation mode between adaptive software, thereby, be applicable to that the middleware under the various amalgamation modes is implanted for the implantation of middleware provides higher flexibility.Because of middleware can be in order to repair BUG and to increase the constantly upgrading of new function, so guarantee that middleware can be stablized, upgrading normally is crucial, and the upgrading of complete machine software is to realize by calling the graft layers interface, and its safety and stability type is guaranteed by the complete machine software provider.
Below by specific embodiment the present invention is described in detail.
At first, the fusion form of clear and definite middleware and complete machine software, when complete machine software and operating mechanism when open fully or part is open to middleware, middleware can be abandoned independence, and selects to be dissolved among the complete machine software.And be the situation of flight data recorder fully for complete machine software, then can only adopt to make middleware have independence, operation depends on the socket that complete machine software provides.This depends on developer and exploitation form.The developer of the developer of middleware and complete machine software may separate in the actual product that has, and also may be to hold two duties with a collection of developer.Situation about having is that complete machine software only need be linked into operation platform, and the more function of individual character will be provided himself, and situation about having then is to utilize middleware and the better amalgamation of complete machine software, more relies on the customized more rich functions of framework of middleware.Has independence as middleware, then only need terminal equipment to provide enough memory spaces to preserve middleware software, middleware has under the path of authority at it realizes at least two passages with catalogue form, simultaneously, preserves and upgrades channel status (as EEPROM) by non-volatile memory device.Be illustrated in figure 2 as the structure of middleware and complete machine software storage, among the figure, a partly represents non-independent middleware and complete machine software configuration, and b partly represents independent middleware and complete machine software configuration.
As shown in Figure 3, the schematic diagram that alternately middleware is carried out data management for digital TV terminal and operation platform, among Fig. 3, middleware place digital TV terminal can comprise OAM (OperationAdministration and Maintenance, operation management maintain) module, startup process (STARTUP) module, interface module, core services module, equipment is transplanted module, OSAL (Operating SystemAbstraction Layer, operating system abstract layer) task module and HAL (Hardware AbstractionLayer, hardware abstraction layer) storage update module etc.To the data management of middleware, download redaction and finish the process of local update except comprising from the server end of operation platform, also need under abnormal conditions, guarantee the stable operation of self.So data management provides a upgrading and backup framework at least, thereby the number and the download location of shielding complete machine software section, the details of the Status Change of software file layout and complete machine software upgrade process, require graft layers that required upgrading and backup interface is provided, by calling corresponding interface, finish the upgrading and the backup of complete machine software.Simultaneously upgrade framework is being safeguarded the starting state and the version information of middleware when needed, can guarantee from returning to normal condition when abnormal conditions occurring, and can select to realize that middleware self finishes upgrading by network.
Data management scheme of the present invention, one of innovation just has been middleware position in complete machine software adaptive, but self maintained upgrade status, the part that can turn to complete machine software realizes upgrading, thereby improved adaptability to terminal equipment, when transplanting, have more flexibility, provide more choices to the developer.
One, the data management scheme that has the middleware of independence
At this moment, middleware has the control authority that self is disposed, and at first separately middleware is carried out data management, then, can further manage complete machine software.
(1) separately middleware is carried out data management
The upgrading middleware can guarantee that middleware still can not enter into latest edition when complete machine software does not possess promotion condition or upgrading failure separately, thereby obtains more rich functions and user experience.
The main flow process of the data management scheme of middleware as shown in Figure 4.
S401: after the startup, judge that middleware needs backup? if desired, carry out the backup flow process of S402, otherwise, the upgrading flow process of execution S403.
Particularly, can need determine whether backup middleware information by calling physical layer interface.
As seen, the principle of middleware being carried out data management is: preferentially carry out the data backup procedure, ability software upgrade process under the situation that does not need to back up.Upgrading and backup flow process can not simplified the processing to running status carrying out in once starting.
(1.1) backup flow process
Middleware adopts binary channels (or multichannel) to guarantee self normal operation, under installation directory, can exist two passage A and B to store middleware, A is as the main channel, and B is as backup path, realizes backup (synchronously) between middleware upgrading and local channel by the state machine that starts process maintenance channel starting state.The process of backup promptly is the process that the data of a passage copy to another passage.
A specific implementation example is as follows:
Middleware software is if be stored in the DEST subregion, and take the double copies of catalogue form: the A channel catalogue is called osA; B passage catalogue is called osB.
Inlet does not participate in upgrading for boot executable file, boot, is fixing start-up code, and which catalogue it starts from according to starting sign decision middleware.Which, whole middleware is started up by script by starting script in the boot decision startup passage.
During install software, earlier software kit is downloaded to interim memory location, and verification.Revising gap marker is " write operation ", subsequently with all the elements deletion under the osB catalogue, backup; Software kit is unziped to the osB catalogue, backup; Revising gap marker is " not checking ", deletion downloaded software bag.
Before middleware starts, judge that by boot relevant startup sign decides the software that starts which passage.
Start totally three of signs.Need guarantee safe storage:
1) pathAorB: from which channel start, 1 is A, and 2 is B;
2) updateA:A gap marker, 6 is normal; 1 write operation; 2 not checkings; 3 failures;
3) updateB:B gap marker, 6 is normal; 1 write operation; 2 not checkings; 3 failures.
The principle that the backup flow process is mainly followed is as follows:
1) backup actions has precedence over the upgrading action, and an action is only carried out in each startup;
When 2) A channel starts, can trigger the upgrading action;
3) undesired as not starting channel status, trigger backup actions.
(1.2) upgrading flow process
The process of software upgrading is: the server executive software version detection process in the operation platform when the software that detects than current software upgrading version, sends to digital TV terminal with the information of recent software and carries out software upgrading.
Those skilled in the art understand, and whole terminal has the version number of unified naming rule, also can be described as major release, corresponding to each software section, no matter be complete machine software or middleware self, the version number of self are arranged all, also can be described as minor release/point release.In the process that server version detects, the major release of terminal can be reported, receive the version number that server end is passed back simultaneously, as two version number's differences, then representative has upgrade requirement, and at this moment, terminal also need be downloaded whole upgrade software tabulation, in the subsequent upgrade action, each software section upgrading is required.When middleware independence, scalable middleware also upgrades its minor release/point release, channel status.
The upgrading flow process is followed following several principles:
1) after starting successfully from passage A, just begin the action of upgrading, promptly channel B is all the time as the passage on probation of redaction;
2) backup actions has precedence over the upgrading action, and backup or upgrading are only finished in each startup;
When 3) two gap markers are " normally ", preferentially start passage A;
4) be in not verified passage and have precedence over " normally " channel start, starting advance sign is " failure ";
5) before " normal channel " started, the gap marker that will start was set to " failure ";
6) arbitrary channel start failure once switches to another channel start;
7) after two gap markers are " failure ", take turns starting two passages;
8) before the startup, standard two flag bits as not belonging to employed value, then are changed to " failure ";
9) after starting successfully, the sign that starts passage is changed to " normally ".
(2) to the data management of complete machine software
After separately middleware being backed up or upgrading, further calling interface upgrading complete machine software, and trigger the change of corresponding complete machine application state information, thus finish backup or upgrading.Detailed process and principle can be referring to above-mentioned data managements to middleware.
Two, middleware does not have the data management scheme of independence
At this moment, middleware merges among complete machine software, the data management of middleware self is included in complete machine software data management interface inside, and data management processes is followed the general frame of complete machine software, just carries out upgrading, backup and the state-maintenance action of middleware no longer separately at middleware.
The middleware that does not have independence, escalation process is all safeguarded its operation information by physical layer interface voluntarily as other complete machine software section.In the AKU of complete machine software, all the elements of middleware have been comprised.At this moment, when being well suited for the complete machine software development, determined software architecture and abnormal condition protection, can conveniently embed middleware as one of them part.
Need to prove, when upgrading complete machine software, at first need to obtain local software information, comprise software sequence number, version number, upgrading order and software kit download path (complete trails+filename) etc.The version number of software section on the contrast server, can determine the corresponding software section of whether upgrading, note 2 points this moment, at first, when middleware independence, middleware will be as first software section, and the sequence number of each complete machine software section need add 1, moreover when the software kit download path is sky, show and do not possess the storage environment of downloading software kit this moment, need return corresponding error, concrete miscue information can be customized.Secondly, after all need upgrading software partly to upgrade to finish, upgrade major release, this more new element be subjected to bottom control, final updating starting state parameter, the change of starting state because of may exist software next time to start after the upgrading time is by this interface, satisfy pent-up demand, improve whole upgrading flow process.
From the above, the middleware upgrading will propose following several functional requirement to graft layers:
1) obtains the complete machine software information, comprise software sequence number, download path, upgrading order and the current version of software section data, correspondence and operation platform;
2) given software kit position, corresponding complete machine software section upgrading realizes;
3) obtain and the major release of new terminal more;
4) complete machine software startup state upgrades, and comprises normal startup, begins upgrading, finishes upgrading, begins backup and finishes these several states of backup;
5) backup of complete machine software is judged and is realized.
Corresponding with said method, the present invention also provides a kind of data administrator based on the digital TV terminal middleware, particularly, this device can be meant digital TV terminal, also can be meant the functional entity in the digital TV terminal, as long as can finish the function of this device, on implementation, can pass through hardware, software or software and hardware combining and realize.
This device comprises middleware independence judging unit and Data Management Unit at least, and wherein: middleware independence judging unit is used to judge the independence of the middleware of digital TV terminal; Data Management Unit is used for managing according to the data of middleware independence to middleware, wherein, if middleware is independent, then carries out data backup or software upgrading at middleware separately; If middleware is not independent, then complete machine software is carried out in data backup or the software upgrade process, finish data backup or software upgrading simultaneously to middleware.
Preferably, when middleware independence, Data Management Unit further calls the interface between middleware and the Digital Television complete machine software after carrying out data backup or software upgrading at described middleware separately, complete machine software is carried out data backup or software upgrading.
Particularly, the course of work of middleware independence judging unit is, by when starting described digital TV terminal, reads the middleware independence sign in the system parameters of digital TV terminal, determines the independence of middleware.
Preferably, Data Management Unit also is used for the execution sequence of the data backup of middleware and software upgrading is controlled, wherein, when when calling physical layer interface and determine to carry out data backup to middleware, the preferential data backup procedure of carrying out, otherwise, ability software upgrade process.
As seen, what the present invention program adopted is unified upgrading and backup framework, take into account middleware and whether had two kinds of situations of independence, strengthened the flexibility of the position in the middleware terminal software framework of living in, security and stability when having satisfied middleware independence, and complete machine software upgrading mechanism is provided, and can make complete machine software mutual by middleware and operation platform, finish the upgrading of self, can solve the upgrading of middleware now and the technical problem of complete machine software upgrading.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
