BRIEF DESCRIPTION OF THE DRAWINGS
[0036] Figure 1 This is a structural schematic diagram of the system in a preferred embodiment of the present invention. DETAILED DESCRIPTION
[0037] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. The present invention is not limited to this embodiment, and other embodiments may also fall within the scope of the present invention as long as they conform to the gist of the present invention.
[0038] In a preferred embodiment of the present invention, based on the above problems existing in the prior art, a safety maintenance system suitable for an on-board intelligent cockpit is provided. Figure 1 As shown, including:
[0039] An intelligent operation module 1, which is disposed in an on-board intelligent cockpit and is used to provide daily operation services for users;
[0040] A security maintenance module 2 is connected to the intelligent operation module 1 and is used to provide security maintenance services to the intelligent operation module 1. The security maintenance module 2 includes:
[0041] A storage protection unit 21, used to store the operation information generated in the service process of the daily operation service and provide storage protection services in the security maintenance service;
[0042] A timed maintenance unit 22, used to provide a timed maintenance service in a security maintenance service to the intelligent operation module 1;
[0043] A management and maintenance unit 23, used to provide management and maintenance services in the security maintenance service to ordinary users and administrators pre-set by the intelligent operation module 1;
[0044] A task maintenance unit 24 is used to configure a task scheduling server to provide task maintenance services in the security maintenance service for multiple pending tasks generated by the intelligent operation module 1.
[0045] Specifically, in this embodiment, taking into account the security issues such as operation information leakage, user authority abnormalities, and task scheduling abnormalities in the on-board smart cockpit of a modern car, the storage protection unit 21 is used to store and maintain the operation information generated during the service process of daily operation services to solve the problem of operation information leakage, and the management and maintenance unit 23 is used to maintain the management authority of ordinary users and administrators to solve the problem of user authority abnormalities, and the task maintenance unit 24 is used to schedule and maintain the pending tasks generated by the intelligent operation module 1 to solve the problem of task scheduling abnormalities.
[0046] In a preferred embodiment of the present invention, a file storage module 3 is further included, connected to a file storage pre-configured in the intelligent operation module 1, and is used to detect whether the file name of the new file exists in the file storage each time the user creates a new file, and when the file name of the new file does not exist in the file storage, output an analysis result indicating that the file name does not exist and display it to the user; and
[0047] When the file name of the new file exists in the file storage, an analysis result indicating that the file name already exists is output and displayed to the user.
[0048] Specifically, in this embodiment, taking into account the security issues of storage file loss and abnormal file storage in the on-board smart cockpit of a modern car, a file storage device is set to save files to solve the problem of storage file loss, and the file storage module 3 is used to detect whether the file name of the new file is repeated each time the user creates a new file, so as to increase the validity of the new file and reduce the repetition rate of the file, thereby solving the problem of abnormal file storage.
[0049] In a preferred embodiment of the present invention, the file storage module 3 includes:
[0050] The first analysis unit 31 is used for detecting whether the file name of the new file exists in the file storage device each time the user creates a new file, and outputting an analysis result indicating that the file name does not exist when the file name of the new file does not exist, and prompting the user to input a file protection code corresponding to the new file; and
[0051] When the file name of the new file exists, an analysis result indicating that the file name already exists is output to prompt the user to modify the file name of the new file;
[0052] The file storage unit 32 is connected to the first analysis unit 31 and is used to bind the file protection code with the corresponding new file and the file name of the new file upon receiving the file protection code input by the user and store the new file in the file storage.
[0053] Specifically, in this embodiment, considering that only detecting whether the file name is repeated to decide whether to create a file lacks certain security and rationality, the first analysis unit 31 will prompt the user to enter a file protection code when confirming that the file name of the new file is not repeated, and bind the file protection code entered by the user to the new file through the file storage unit 32 to ensure that the new file will not be opened at will by others, thereby increasing the security of the new file.
[0054] Preferably, when creating a new file, first determine whether the file name already exists. If so, prompt the user to "re-enter the file name!", otherwise prompt the user to "please enter the file protection code!". After the user enters the file protection code, the new file will be successfully created.
[0055] In a preferred embodiment of the present invention, a file search module 4 is further included, connected to the file storage in the intelligent operation module 1, and the file search module 4 includes:
[0056] The second analysis unit 41 is used to determine whether the file name exists in the file storage when the user inputs a file name for search and output an analysis result indicating that the file name exists if the file name exists to prompt the user to input a file protection code corresponding to the file name; and
[0057] When the file name does not exist, an analysis result indicating that the file name does not exist is output to prompt the user to re-enter the file name;
[0058] A third analysis unit 42, connected to the second analysis unit 41, is used to determine whether the file protection code matches the file protection code bound to the file name when the file protection code is received and to open the file corresponding to the file name when the match succeeds; and
[0059] When the matching is unsuccessful, an analysis result indicating that the file protection code is wrong is output to prompt the user to re-enter the file protection code.
[0060] Specifically, in this embodiment, after the file storage unit 32 binds the new file and the corresponding file protection code, when the user searches for the required file, he not only needs to enter the correct file name, but also needs to enter the file protection code corresponding to the file. The file can only be opened when both the file name and the file protection code are correct, thereby increasing the security of the file.
[0061] Preferably, in actual situations, it can also be arranged that when a user inputs a file name and wants to find a file and view the content in the file, it is determined whether the file name exists. If so, the file is opened to view the content of the file. Otherwise, a prompt "File name does not exist!" is given to the user, and the user is asked to re-enter the file name. When the user wants to write content in the file, it is first determined whether the file name exists. If so, the user is prompted "Please enter the file protection code!". If not, the user is prompted "File name does not exist!" and the user is asked to re-enter the file name. After the user enters the file protection code, it is determined whether the file protection code is correct. If correct, the file is opened for the user to write. If incorrect, the user is prompted "File protection code error!" and the user is asked to re-enter the file protection code.
[0062] Preferably, the number of times a user can input a file protection code may be limited, and when the file protection code input by the user is incorrect for a certain number of consecutive times, the user is prohibited from inputting a file protection code.
[0063] Preferably, the file protection code is a security guarantee for the file. With the continuous enhancement of information technology, many people steal other people's important data or information by obtaining other people's files, so many users set file protection codes to prevent the leakage of their file contents. Sometimes users will set their own passwords at will, and may need to modify the password to be more stringent after setting it. Therefore, a process for modifying the file protection code can be designed to facilitate users to make changes.
[0064] Preferably, when the user inputs the file name of a file whose code they want to modify, it is first determined whether the file name exists. If so, a prompt is given to "Please enter the file protection code of the original file"; if not, a prompt is given to the user to "The file name does not exist" and the user is asked to re-enter the file name. After the user enters the file protection code, it is determined whether the file protection code is entered correctly. If correct, the user is prompted to "Please enter a new file protection code"; if incorrect, the user is prompted to "The file protection code is wrong" and the user is asked to re-enter the file protection code. After the user enters the new file protection code, the new file protection code is bound to the file name of the original file and the user is prompted to "The file protection code has been modified successfully!".
[0065] In a preferred embodiment of the present invention, the storage protection unit 21 includes:
[0066] The storage subunit 211 is used to provide a translation backup buffer to store the operation information generated during the service process of the daily operation service;
[0067] The protection subunit 212 is connected to the storage subunit 211, and is used for continuously monitoring the translation lookaside buffer and, when receiving access exception information output by the translation lookaside buffer, issuing an alarm to the user according to the access exception information.
[0068] Specifically, in this embodiment, there are multiple domains in the translation backup buffer, and the application software installed in the intelligent operation module 1 often only accesses one domain. When an application software illegally accesses the storage space of other domains, access exception information will be generated, and the protection sub-unit 212 will alarm the user based on the access exception information.
[0069] Preferably, the user can contact the maintenance personnel of the intelligent operation module 1 for corresponding processing according to the access abnormality information.
[0070] In a preferred embodiment of the present invention, the intelligent operation module 1 is pre-configured with multiple individual counters and a corresponding alarm. The timing maintenance unit 22 continuously counts a real-time value of each individual counter, and controls the corresponding alarm to warn the user when the real-time value is greater than a preset rated value.
[0071] Specifically, in this embodiment, in order to meet the electronic reliability and real-time requirements of modern automobiles, it is necessary to improve the timing mechanism of the intelligent operation module 1 as much as possible to speed up the response speed to timing events. The general timing mechanism is composed of a software counter and an alarm. In this system, the software counter is replaced by a hardware counter, and each output comparison channel in the hardware counter is individually transformed to set each output comparison channel as a separate counter, and each separate counter is connected to an alarm. The hardware counter composed of multiple separate counters and the alarm form an optimized timing mechanism and are applied to the intelligent operation module 1, which can effectively improve the response speed to timing events.
[0072] Preferably, the original software counter can only count the number of occurrences of a single timed event each time, while the optimized hardware counter can count the number of occurrences of multiple timed events at the same time, thereby increasing the scope of use of timed events. In addition, the original software counter needs to count multiple types of timed events, resulting in excessive memory usage and slow response speed. The optimized hardware counter includes multiple separate counters, each of which counts one type of timed event, which can effectively reduce memory usage and improve response speed.
[0073] In a preferred embodiment of the present invention, a plurality of application software are pre-installed in the intelligent operation module 1, and the management and maintenance unit 23 includes:
[0074] The password maintenance subunit 231 is used to provide an identity information table, and pre-store the management authority of each common user and administrator in the identity information table, as well as an identity password corresponding to each common user and administrator;
[0075] The identity matching subunit 232 is connected to the password maintenance subunit 231, and is used to match the identity password in the identity information table when receiving the identity password input by the user and provide the user with corresponding management rights when the match is successful; and
[0076] If the match fails, it will prompt that the user's identity password does not exist;
[0077] The application maintenance subunit 233 is used to continuously count the usage time of each application software and control the application software to suspend providing corresponding daily operation services when the usage time is less than a preset standard time.
[0078] Specifically, in this embodiment, the management authority of each common user and administrator in the identity information table is maintained by the password maintenance subunit 231, and the corresponding management authority is granted to the user by the identity matching subunit 232, which can greatly reduce the probability of abnormal authority problems.
[0079] Preferably, considering that a large number of application software are installed on the intelligent operation module 1, and users use less than half of these application software most of the time, however, even if the users do not use them, these application software will still run in the background, posing a risk of attracting attackers. Therefore, the usage time of each application software is counted through the application maintenance sub-unit 233 and the service of the application software is suspended when the usage time of the application software is less than the standard time.
[0080] In a preferred embodiment of the present invention, the management and maintenance unit 23 also includes a log maintenance subunit 234, which is used to detect whether there is a system log in the intelligent operation module 1 at a preset time interval indicating that an attacker has entered or accessed, and to issue an alarm to the user when a system log exists.
[0081] Specifically, in this embodiment, the system log often records the activities occurring on the system, including whether an attacker has successfully entered or attempted to access the system. Therefore, it is quite necessary to regularly check the system log. The log maintenance subunit 234 detects whether there is a system log indicating that an attacker has entered or accessed the system at a preset time interval, and when such a system log exists, an alarm is prompted to the user to improve security.
[0082] In a preferred embodiment of the present invention, the task maintenance unit 24 includes:
[0083] The first maintenance subunit 241 is used to provide a task queue and add each to-be-processed task to the task queue, and sort each to-be-processed task in descending order of priority based on the priority corresponding to each to-be-processed task;
[0084] The second maintenance subunit 242 is connected to the first maintenance subunit 241, and is used to detect whether the task scheduling server generates a scheduling opportunity and control the task scheduling server to execute the pending tasks ranked first in the task queue when the scheduling opportunity is generated, and delete the pending tasks from the task queue after the processing is completed.
[0085] Specifically, in this embodiment, for the intelligent operation module 1, simply relying on improving the scheduling algorithm can no longer greatly improve the real-time performance of the intelligent operation module 1 in processing tasks. Therefore, hardware logic is used to implement task scheduling. During the specific implementation, a combinational circuit is used to implement a hardware scheduler as a task scheduling server. Since the hardware logic runs independently of the central processing unit of the intelligent operation module 1 and does not occupy the processing time of the central processing unit, the saved processing time is used to execute the tasks to be processed, thereby improving the schedulability, reliability and real-time performance of the tasks to be processed.
[0086] In a preferred embodiment of the present invention, the task maintenance unit 24 also includes a third maintenance sub-unit 243, which is connected to the first maintenance sub-unit 241 and is used to control the third maintenance sub-unit 243 to sort the remaining pending tasks and new pending tasks in the task queue in order of priority from high to low when the intelligent operation module 1 generates a new pending task.
[0087] Specifically, in this embodiment, the core of the second maintenance sub-unit 242 is to determine the next pending task to be executed at each scheduling opportunity of the task scheduling server according to the scheduling algorithm, and control the task scheduling server to switch. Therefore, the task queue needs to be re-sorted every time the intelligent operation module 1 generates a new pending task. The third maintenance sub-unit 243 is used to detect whether the intelligent operation module 1 generates a new pending task and control the third maintenance sub-unit 243 to re-sort the task queue when the intelligent operation module 1 generates a new pending task.
[0088] The above are only preferred embodiments of the present invention, and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of this specification and illustrations should be included in the protection scope of the present invention.
