Detailed Description
The invention will be further explained with reference to the drawings and the embodiments.
Example (b): with reference to figures 1-3 of the drawings,
a vehicle-mounted terminal dual system comprises a first system and a second system, wherein private security applications are installed in the first system, non-private ecological applications are installed in the second system, and a mirror image system which runs in a container and is in a mirror image relationship with the second system is deployed in the first system; the first system is a working system based on a Linux system, the second system is a living system based on an Android system, and the mirror image system is ATL (Android To Linux) based on the Android system; the mirror image system is specifically configured in such a way that a system management module of the main system acquires application information of the non-private application from the second system through the SDK of the Android system, sends the application information to the mirror image system, and displays the application information through the first system.
The system also comprises a main system, wherein the main system is respectively interacted with the first system and the second system; the main system comprises a system management module for managing the first system and the second system, and a system switching module for controlling switching between the first system and the second system.
Based on the system, the invention also provides a method for realizing the double systems of the vehicle-mounted terminal, which comprises the following steps,
s1, the system management module of the main system traverses the non-private ecological application in the second system to obtain the application information; the application information comprises an application program package name and an icon.
S2, the system management module transmits the application information to a mirror image system in the first system, and displays the application information through the first system; and displaying the application information in the mirror image system through a homepage QT application program of the first system.
S3, installing or starting the application by clicking the non-private ecological application or the private security application displayed in the first system;
s4, judging whether the application at the click position is a non-private ecological application corresponding to the second system or not through the mirror image relationship between the mirror image system and the second system, if so, executing S5, otherwise, executing S6; specifically, whether the application is the non-private ecological application in the second system is judged by judging whether the application package name corresponding to the application at the click position corresponds to the non-private ecological application in the second system.
S5, starting the application through the second system;
and S6, starting the application through the first system.
When the non-private ecological application is installed or updated in the second system, the system management module is informed, the system management module sends the installation or update information to the mirror image system, and the application is displayed or updated by the homepage QT application program of the first system.
Specifically, in order to achieve the above effects, the technical problem to be solved includes a dual-system switching method for the first time, and this part may use the existing dual-system switching technology, which will be described briefly later. Because the system switching problem is not the core content considered by the invention, the invention mainly focuses on how the working system supports the expansion of the Android system ecology. Namely, the work system realizes the support To ATL (android To Linux) through a container technology.
In order To support the extension of the Android system ecology and prevent the redundancy of codes, the atl (Android To linux) parts of the living system and the working system need To implement code reuse. The dual system completely reuses a set of open system codes, which inevitably causes interference and causes unpredictable problems. For this case, the special logic portion needs to be distinguished by macro definition, and thus there is a large modification workload.
Moreover, when the version of the Android system is upgraded, the synchronous upgrading of the ATL (Android To Linux) is required, mainly comprising the upgrading of a HAL (HAL layer calling) mode and the upgrading of an ATL (Android To Linux) code, wherein the upgrading is determined according To the issued Android high version, otherwise, the problem that the application using the Android ecological extended function cannot be supported exists.
Finally, it is also necessary to consider an application developed in a working system, and this application is also implemented in consideration of system security. The QT can be used for developing an application program, similar to Android native system application, basic applications such as telephone, homepage, short message, camera, music, system setting and the like can be realized, and development can also be performed according to actual requirements.
The implementation of the application mainly aims at the large premise that the leakage of personal privacy data in the current vehicle-mounted system and the current mainstream Android vehicle-mounted system are possibly limited to be used or charged at any time, and provides a safe and reliable vehicle-mounted double system for supporting mutual switching of working modes and living modes. The double systems not only ensure that the living system and the working system are mutually isolated and do not interfere with each other, but also realize the expansion of supporting the ecological application of the Android system in the working system, and the invention is further explained by combining the attached drawings.
As shown in fig. 1, the method mainly includes the following aspects:
(1) first, a main system is required for the control and management of the working system and the living system. The main system mainly realizes the mutual switching scheme between the working system and the living system and provides the functional service of the basic platform. The safe working system can be started as a default system, and if system switching is required, the working system or the living system directly interacts with the main system, and the working system or the living system is handed to the main system for system switching after an instruction is issued. The system switching is also a mature technology, the method is diversified, the system switching is not the main point of the important introduction of the invention, and the system switching management method is not described in detail.
(2) The working system is the core of the invention, safe application programs are realized by using a safe Linux system QT technology, and an Android virtual machine is introduced, so that the system is compatible with mainstream ecological application of the current vehicle-mounted system.
(3) The living system is a mainstream system used by the current vehicle-mounted terminal, namely an Android system, and comprises open mainstream application, and the living system is very flexible in modification and expansion.
Fig. 3 illustrates a working and living system, both of which are described in relation to implementation. The Android system atl (Android To linux) is developed in a working system, and the Android system atl (Android To linux) runs in a container, wherein the atl (Android To linux) scheme realizes compatibility of mainstream vehicle-mounted ecosystem application software in the working system, and then two main aspects of the working system security application and how To realize the Android system ecosystem compatibility are introduced:
as shown in fig. 2, the operating system uses a more stable and secure Linux system, which is more advantageous than a more open Android system in terms of security. Compared with an APK program developed by a JAVA language, the application program developed by the QT has qualitative improvement on code safety and cracking difficulty. Although Android programs also have some technologies to prevent easy cracking, such as code confusion and the like, the difficulty of decompiling and cracking the APK file is still far lower than that of an application program developed by QTC/C + +.
As can be seen in fig. 2, when the working system is started, the homepage needs to show the application program icon, and a special starting scheme needs to be established for the icon display. When the system is started, the system management module needs to use an interface Software Development Kit (SDK) of the Android system to traverse the installed Android application program, so as to obtain information such as application program names and icons, and notify the obtained information to a homepage QT application program of the Android system for displaying. Thus, the homepage application not only shows the QT application, but also shows the Android application.
After successful display is completed, a special starting scheme also needs to be customized for starting the QT application program and the ATL-compatible Android application program in the working system. As can be seen in fig. 2, when an application icon is clicked, the homepage application program may first obtain an application package name of a click position, and if the package name can be obtained, an interface in an interface Software Development Kit (SDK) of the Android system is used to start the corresponding Android application program. If the package name of the clicked application program cannot be obtained, the clicked application program is regarded as the QT application program, and therefore the self QT application program starting process in the working system is executed.
The process of installing the application program is similar to the system starting process introduced above, and mainly includes actively notifying a system management module when installation is completed or new Android application update is detected, processing by the system management module, and then submitting the new installation application to QT homepage application program for updating and displaying.
In addition, the implementation of the ATL (android To Linux) scheme depends on a container technology, the system of the container and the host machine realizes resource sharing, the implementation efficiency is improved, and the performance loss is not too high. After the container technology is applied, each container uses a kernel and a common program library which are the same as those of the host, and in addition, the process executed in the container is equivalent to the process operated in the host, so that the operation and the processing of the system management module on the container are facilitated. According to the realization, the isolation capability between the containers is stronger, so that living and working systems can run independently better.
Furthermore, the physical device resources can be allocated to different virtual machines by taking advantage of the virtualization technology of the container. Each virtual machine is a complete operating system, and corresponding deployment is completed through the mirror image of the corresponding system. Here the image resembles an operating system, while the container resembles the virtual machine itself, which can be started, stopped, deleted, etc., and each container is isolated from the others. Due to the advantages of the container technology, two containers can be used in a proper order, and a working system with a Linux system mirror image and a living system with an Android system mirror image are respectively deployed, so that a vehicle-mounted double system which is expected by the invention and has mutually switchable working modes and living modes is achieved.
An ATL (Android To linux) module in the working system is a further extended application To the container technology, deploys a mirror image corresponding To the living system, and selectively runs and loads by defining a macro similar To the Android ATL. And the multiplexing of the living system and the working system to the Android codes is realized.
With the continuous improvement and function increase of Google on the Android system, it may also be involved that when Google needs To upgrade the version of the Android system, the working system needs To modify and upgrade the synchronization of atl (Android To linux) and the shared Android system code in the living system. Not only needs to transplant HAL layer HIDL interface newly added to Android, but also needs to perfect adaptation work such as code modification and synchronous upgrade of an ATL macro control part.
Finally, with the increasing international situation, if the day is the mainstream Android system is restricted or charged for use. The invention provides a safe and reliable vehicle-mounted double-system mode for supporting mutual switching of working modes and living modes, which can not only quickly and effectively provide the realization idea and the solution of a new system, but also be safely and reliably compatible with the ecology supported by the original vehicle-mounted system.
In order to deal with the great change which possibly occurs at any time, the invention provides a system which is compatible with the current mainstream vehicle-mounted application and can solve the safety problem, wherein one system is a closed and safe working system (such as a Linux system) and the other system is an open living system (such as an Android system). Switching selection is carried out according to the use scene, namely, mutual switching between a working system and a living system is supported.
The working system not only can develop functions and basic applications with high confidentiality required by the industry, but also can use a mature container technology to operate an open mainstream system. Therefore, the installation and the operation of the ecological application supported by the open mainstream system on the working system are achieved, and the working system has better system expansibility while supporting higher confidentiality.
The open life system is similar to the vehicle-mounted system which is generally used at present and is also an independently operated system. However, due to the openness and the openness of the system, the system has the risk of being easily cracked in the aspect of safety and the like. Plus uncertainty factors that may be limited in use or charged at any time. The system is only suitable for use scenes which are not limited to use and have low requirements on personal privacy and safety at present because the system has the characteristics of more flexibility, convenience and the like in open operation and use.
Therefore, with the vehicle-mounted dual system supporting the mutual switching of the working mode and the living mode, the obvious problem of the traditional vehicle-mounted system can be perfectly solved, and the expansibility of the Android system is compatible.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the technical solutions, and those skilled in the art should understand that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all that should be covered by the claims of the present invention.
