Detailed Description
In order to make the above objects, features and advantages of the present invention more comprehensible, embodiments accompanied with figures are described in detail below.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than as described herein, and therefore the present invention is not limited to the specific embodiments disclosed below.
A flowchart is used in the present application to describe the operations performed by a system according to embodiments of the present application. It should be understood that the preceding or following operations are not necessarily performed in order precisely. Rather, the various steps may be processed in reverse order or simultaneously. At the same time, other operations are added to or removed from these processes.
Embodiments of the present invention describe a method of dynamically configuring and operating a system ROM file of an electronic device and an electronic device that can dynamically configure and operate its system ROM file.
In one embodiment, the system ROM files include Boot files, kernel (Kernel) files, system program files, and application installation Boot files. The electronic device may be connected to the server side via a network.
FIG. 1 is a flow chart of a method of dynamically configuring and operating a system ROM file for an electronic device in accordance with an embodiment of the present application. As shown in FIG. 1, the method includes step 101, loading a startup file. Step 102, loading the kernel file. Step 103, loading the system program file. Step 104, reading a pre-configured SN number from a non-volatile storage area of the electronic device. Step 105, obtaining a profile file corresponding to the pre-configured SN number in the mapping table. And 106, acquiring the application installation configuration files of the corresponding models from the server side by one or more application installation starting files according to the profile files. Step 107, installing one or more applications based on the installation configuration file.
The electronic device performs the device startup and initialization based on a Read-Only Memory (ROM) file for use by a user.
Specifically, in step 101, a Boot (Boot) file in a system ROM file is loaded. Heretofore, a power-up link of the electronic device has been included in practice to power up portions of the electronic device. After the electronic device is powered on, system ROM file configuration of the device is started. In step 101, a Boot file (which may also be referred to as a Boot file) is loaded. The startup file (or a plurality of files included in one startup folder) includes a startup boot file after the system is started up and a configuration instruction which is the most basic for system operation. Such as a boot icon and an initial boot of the system device.
In step 102, a Kernel (Kernel) file is loaded. The kernel file (which may also be multiple files in a kernel folder) is a file that further configures the operation of the system after loading a Boot (Boot) file. Such as memory management of the system, drive configuration, data input and output operation management, interrupt handling, and the like.
In step 103, a system program file is loaded. The system program file is a basic file which enables the electronic device to realize normal system operation after the electronic device is powered on and starts a Boot loading and starting (Boot) file and a Kernel (Kernel) file, and comprises the operation and management of each component module of the system. Such as a display module, an input-output module, a memory module, etc. Meanwhile, the normal running of the system program is also the basis for the subsequent application program installation.
In one embodiment, the system program file includes a mapping table of SN numbers and profile files. The information of the profile file may determine the installation model of the application in the system ROM file.
In some embodiments, the SN number is determined from business logic of the operating scenario of the electronic device. The SN number may be, for example, a code consisting of several bytes of characters. The information recorded by the partial bytes in the SN number may indicate the difference in the operating scenario of the electronic device, and thus the corresponding business logic. For example, the electronic device may be a vending device, and the application scenario of the device may be, for example, a supermarket, a college restaurant, a mini-retail store, or the like. The operation modes of the corresponding devices of the application scenes, namely, the business logic, are different. The business logic of the multiple operational scenarios is numbered and forms a code. And forming an SN number of business logic corresponding to the operation scene of the electronic equipment based on the code.
In one embodiment, the SN number may be an 8-byte or 10-byte binary code. The codes of the first byte and the second byte from the low level to the high level can indicate the product name of the electronic device or the project name corresponding to the developed program, such as F2, TD and the like, which are used for converting the codes and pointing to specific characters with customized meanings. The third byte and the fourth byte may be encodings of the operational scenario and business logic of the electronic device. Other bytes of the SN number may indicate the date of manufacture of the electronic device, lot number, serial number, etc. In addition, several spare bytes may be set aside to label potentially more information.
Different SN numbers indicate business logic of different application scenarios of the electronic device. For example, the passenger flow of a large supermarket is diversified, and the mobility is high. The user group of the college restaurant is relatively less mobile. Sales, inventory, etc. for small retail stores are quite different from those for large supermarkets. These determine the business logic of the electronic devices installed in different application scenarios. Correspondingly, application programs installed in electronic equipment in different application scenes also have different requirements so as to better meet the requirements of equipment users with different roles in different application scenes.
In one embodiment, the information of the profile file may determine the installation model of the application in the system ROM file. And the SN number indicates the business logic of the different application scenarios of the electronic device. And the SN number and the profile file are associated through a mapping table of the SN number and the profile file contained in the system program file. The profile file includes specific attribute information of the software.
In step 104, a pre-configured SN number is read from a non-volatile storage area of the electronic device. The nonvolatile memory area is, for example, flash (Flash memory). The SN number may be burned in the nonvolatile memory area at the time of factory production of the electronic device.
In step 105, a profile file corresponding to the pre-configured SN number in the mapping table is obtained. The profile file includes definition information of the type of application to be installed on the electronic device. And the limit information of the application program model corresponds to the business logic of the operation scene of the electronic equipment. The limitation information may be presented in the form of a series of character strings.
For example, if the electronic device is a swipe code payment device or a face-brushing payment device, or other types of vending devices, the business logic in different application scenarios also has a difference. Such as a supermarket, a college supermarket or restaurant, a mini-retail store, etc.
The different profile files comprise the limiting information of the application program model, and the limiting information corresponds to the business logic of different application scenes of the electronic equipment marked by the SN number. And the profile file and the SN number are associated through the mapping table of the SN number and the profile file contained in the system program file. The information of the profile file can be read and parsed by the system program.
In step 106, the one or more application installation start files obtain the application installation configuration files of the corresponding model from the server according to the profile file. In some embodiments, the application installation profile of the corresponding signal may also be obtained from a local storage of the electronic device. The application installation start file is, for example, an apk format file, or an exe format file, and may be other formats. The locally stored application installation profile may be obtained from the server side over the network during other periods of time. The connection between the electronic equipment and the server side is also convenient for acquiring the application program installation configuration file required by updating during the subsequent maintenance of the ROM file.
For example, an application program to be installed on an electronic device is developed in different models corresponding to different application scenarios such as a supermarket, a small retail store, a unit or a school restaurant. When the application program is installed, applications of corresponding models (or versions or different models in the same version) need to be installed according to the use situation of the electronic device. And the application program installation starting file obtains the installation configuration file of the program with the corresponding model according to the profile file.
In step 107, one or more applications are installed based on the installation configuration file. The installed application programs of different models can correspond to the differences of application scenes, and corresponding differences are set on business logic. For example, according to different sales scenarios of the electronic device application, there are differences among pushing programs of the commodities, summary of data, and statistical analysis programs.
In some embodiments, the electronic device further comprises an input-output device. The input-output device is, for example, a display device, an image pickup device, and/or a code scanning device. The display device is, for example, a display screen or an operation panel. The camera device is, for example, a face recognition camera, and is used for recognizing scenes such as face recognition and/or face payment. The code scanning equipment can be used for scanning code recognition or code scanning payment and other scenes.
The method for dynamically configuring and operating the system ROM files of the electronic equipment can compile ROM files suitable for a plurality of application scenes according to different scenes to be applied by the equipment in the production and development processes of software and hardware of the electronic equipment. In the starting and initializing process of the electronic equipment, dynamic configuration and operation are carried out based on the compiled ROM file, and the initialization of the system on the electronic equipment is realized.
The method for dynamically configuring and operating the system ROM file of the electronic equipment can realize that the ROM file of the same version is suitable for a plurality of application scenes and different business applications. When the electronic equipment is developed based on a public board card, the dynamic configuration can be realized in the starting and initializing processes of the equipment by adapting a plurality of application scenes of the electronic equipment through the ROM files of the same version without compiling and debugging different ROM files aiming at different equipment application scenes. The development and maintenance cost of ROM is greatly saved, and the development period of equipment software is shortened, so that the marketing period of products is shortened.
In some schemes, a mode of adding a board card ID on a hardware board card of the electronic equipment and adapting different board card IDs through the ROM file are adopted, so that a version of ROM file corresponds to various board cards. However, in order to adapt to different application scenes, a plurality of different boards are required to be configured, so that the system structure becomes more complex, and the cost is correspondingly increased.
In addition, some technical schemes are also provided, by storing some configuration information in a nonvolatile storage area of the equipment, the system reads information of a system processor or information of set hardware when the system is started up, so as to realize the corresponding application of the configuration system. However, in this technical solution, some properties of the system are fixed, and the hardware configuration of the device also limits the use scenarios, so that the application in multiple scenarios cannot be compatible.
According to the method for dynamically configuring and operating the system ROM file of the electronic equipment, the electronic equipment determines the program installation model in the corresponding application scene according to the information of the profile file corresponding to the pre-configured SN number in the starting and initializing process of the system through the SN number in the system program file and the mapping table of the profile file. Dynamic configuration and operation of the system ROM file are realized.
The application also provides an electronic device capable of dynamically configuring and running the system ROM file, and the electronic device can be connected with a server through a network. The system ROM files include a boot file, a kernel file, a system program file, and an application installation boot file. The electronic device includes a first memory, a second memory, and a processor.
Wherein the first memory stores a system ROM file. The system ROM files include a boot file, a kernel file, a system program file, and an application installation boot file. The second memory stores computer readable instructions.
