Detailed Description
The invention will be further described with reference to the drawings and examples.
Examples: with reference to figures 1-3 of the drawings,
A vehicle-mounted terminal double system comprises a first system and a second system, wherein a private security application is installed in the first system, a non-private ecological application is installed in the second system, and a mirror image system which operates in a container and is in 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 specifically comprises a system management module of a main system, wherein the system management module of the main system obtains application information of a non-private application from a second system through an SDK of an Android system, sends the application information to the mirror image system and displays the application information through a first system.
The system also comprises a main system which is interacted with the first system and the second system respectively; the main system includes 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, a system management module of a main system traverses a non-private ecological application in a second system to acquire application information; the application information comprises application package names and icons.
S2, the system management module transmits the application information to a mirror image system in the first system, and the application information is displayed through the first system; the application information in the mirror image system is displayed through a homepage QT application program of the first system.

When the non-private ecological application is installed or updated in the second system, the system management module is notified, the system management module sends the installation or update information to the mirror system, and the application is displayed or updated by the homepage QT application program of the first system.
In particular, in order to achieve the above effect, the technical problem to be solved includes a dual system switching method, and this part may use an existing dual system switching technology, which will be described in detail 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 ecology of the Android system. I.e. the operating system achieves support for ATL (Android To Linux) through container technology.
In order to support the expansion of the Android system ecology and prevent redundancy of codes, the ATL (Android To Linux) part of the living system and the working system needs to realize code multiplexing. The dual system completely multiplexes a set of open system codes, which tends to cause interference and cause unpredictable problems. For this case, the special logic portion needs to be distinguished by macro definition, so there is much modification workload.
Furthermore, the method also synchronously upgrades ATL (Android To Linux) when the version of the Android system is upgraded, mainly comprises upgrading the HAL layer calling mode and upgrading ATL (Android To Linux) codes, and the part is required to be based on the published Android high version, otherwise, the problem that some extended function applications using Android ecology cannot be supported exists.
Finally, it is also a consideration for applications developed in the working system, and this application is also implemented in view of system security. The QT can be used to develop application programs, and the Android-like native system application can realize basic applications such as telephone, homepage, short message, camera, music, system settings, etc., and can also be developed according to actual requirements.
The implementation of the application mainly aims at the 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 use or charge at any time, and provides a safe and reliable vehicle-mounted double system supporting the mutual switching of working and living modes. The dual system not only ensures that living and working systems are isolated from each other and do not interfere with each other, but also realizes the expansion of supporting the ecological application of the Android system in the working system, and the application is further described below with reference to the accompanying drawings.
As shown in fig. 1, mainly includes the following aspects:
(1) First, a main system is required for control management of a work system and a living system. The main system mainly realizes a mutual switching scheme between the working and living systems and provides basic platform functional services. The safe working system can be started as a default system, and if the system is to be switched, the working system or the living system directly interacts with the main system and sends out instructions to the main system to switch the system. The system switching is also a mature technology, the method is diversified, the system switching is not the key 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, and besides the safe application program is realized by using the safe QT technology of the Linux system, the Android virtual machine is also introduced, so that the system is compatible with the mainstream ecological application of the current vehicle-mounted system.
(3) The living system is operated by a main stream system, namely an Android system, used by the current vehicle-mounted terminal, wherein the system comprises an open main stream application, and the transformation and the expansion of the system are very flexible.
As shown in fig. 3, where both the work and living systems are illustrated with respect to implementation. The Android system ATL (Android To Linux) running in the container and the security application developed in the working system, wherein the ATL (Android To Linux) scheme realizes the compatibility of the application software of the main vehicle-mounted ecological system in the working system, and the two main aspects of the security application of the working system and how to realize the compatibility of the ecological application of the Android system are described as follows:
As shown in fig. 2, the working system uses a more stable and safe Linux system, which is more advantageous in terms of safety than a more open Android system. Compared with an APK program developed by JAVA language, the application program developed by QT has a qualitative improvement in code security and cracking difficulty. Although Android programs also have some techniques to prevent easy cracking, such as code confusion, APK file decompilation cracking difficulty is far lower than QT C/c++ developed applications.
As can be seen in fig. 2, when the operating system is started, the home page needs to present application icons, and a special start-up scheme needs to be formulated for the display of the icons. When the system is started, the system management module needs to use an interface software development kit (Software Development Kit, SDK for short) of the Android system to traverse the installed Android application program, so that information such as application program names and icons is obtained, and the obtained information is notified to a homepage QT application program of the Linux system for displaying. In this way, the homepage application not only displays the QT application program, but also displays the Android application program.
After successful display, the operating system also needs to customize a specific starting scheme in order to start the QT application and the Android application compatible with the ATL. In fig. 2, when the application icon is clicked, the homepage application program will first obtain the package name of the application program at the clicking position, and if the package name can be obtained, the corresponding Android application program is started by using the interface in the interface software development kit (Software Development Kit, abbreviated as SDK) of the Android system. And if the package name of the clicked application program cannot be acquired, the clicked application program is considered to be the QT application program, so that the starting flow of the QT application program of the self in the working system is executed.
The installation application program flow is similar to the system starting flow introduced above, and mainly the system management module is actively notified after the installation is completed or the update of a new Android application is detected, and after the system management module processes the new Android application, the new installation application is updated and displayed by the QT homepage application program.
In addition, the implementation of ATL (Android To Linux) scheme depends on container technology, the system of container and host realizes shared resource, the implementation efficiency is improved, and the performance loss is not too high. After the container technology is applied, the kernel and the public program library which are the same as the host are used in each container, and the processes executed in the containers are equivalent to the processes running in the host, so that the system management module can conveniently operate and process the containers. According to the implementation, the isolation capability between the containers is stronger, so that the living and working systems can also operate independently better.
Furthermore, physical device resources may be allocated to different virtual machines using the advantages of the container's virtualization technology. Each virtual machine is a complete operating system, and the corresponding deployment is completed through the mirror image of the corresponding system. Here the image resembles an operating system and the containers resemble the virtual machine itself, which can be started, stopped, deleted, etc., and each container is isolated from the other. Due to the advantages of the container technology, the two containers can be used in a reasonable way and respectively provided with the working system of the Linux system mirror image and the living system of the Android system mirror image, so that the vehicle-mounted double system which is expected to be safe, stable and reliable and has mutually switchable working and living modes is achieved.
A ATL (Android To Linux) module in the working system is a further expansion application of 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. The Android codes are multiplexed by the living system and the working system.
Along with the continuous perfection and function increase of Google on an Android system, when Google needs to upgrade an Android system version, a working system needs to modify and upgrade the Android system code synchronization shared in ATL (Android To Linux) and a living system. The adaptation work such as code modification and synchronous upgrading of the ATL macro control part is completed besides transplanting the HAL layer HIDL interface newly added in the Android.
Finally, with the increasing severity of international situation, if there is one day when the mainstream Android system is limited to use or charged for use. The invention provides a safe and reliable vehicle-mounted double-system mode supporting the mutual switching of working and living modes, which not only can rapidly and effectively give out the realization thought and solution of a new system, but also can be safely and reliably compatible with ecology supported by the original vehicle-mounted system.
In order to cope with the possible great change at any time, the invention provides a system which can be compatible with the current mainstream vehicle-mounted application and can solve the safety problem, wherein one system is a relatively closed and safe working system (such as a Linux system) and another relatively open living system (such as an Android system). The switching selection is made according to the use scenario, i.e. the mutual switching between the working system and the living system is supported.
The working system can develop functions and basic applications with high confidentiality required by industry, and can also use a mature container technology to operate an open mainstream system. Therefore, the installation and operation of the ecological application supported by the open mainstream system on the working system are achieved, so that the working system supports higher confidentiality and has better system expansibility.
The open living system is similar to the vehicle-mounted system which is commonly used at present, and is also a system which operates independently. However, the system has the risk of being easily broken in terms of safety due to the openness and openness of the system. And the uncertainty factors such as limited use or charging exist at any time. And the system has the characteristics of open operation, more flexibility and convenience in use and the like, and is only suitable for use scenes which are not limited in use at present and have low requirements on personal privacy and safety.
Therefore, after the vehicle-mounted double systems supporting the mutual switching of the working mode and the living mode are provided, 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 for illustrating the technical solution of the present invention and not for limiting the technical solution, and those skilled in the art should understand that modifications and equivalents may be made to the technical solution of the present invention without departing from the spirit and scope of the present invention, and all such modifications and equivalents are included in the scope of the claims.
