Detailed Description
The following description of the embodiments of the present application will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the application are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
FIG. 1 is a flow diagram of a vehicle backup warning method provided in accordance with one or more embodiments of the present application.
The vehicle backup warning method shown in fig. 1 includes:
step S1, receiving information of an external system, wherein the information comprises fault type information generated by the external system, and the external system processes abnormal states of the fault type information;
and S2, starting a preset alarm according to the information of the received external system.
Through the scheme, the following beneficial technical effects are obtained:
the application recognizes the working states of other systems by receiving the information of other systems on the filtering bus, and recognizes the abnormal state when the system processes the interactive fault data according to the functional relation among the systems, thereby playing the role of alarming the working states of other systems.
According to the application, by checking the fault data information and executing the state information of the warning command in the fault data, the abnormal time interval of the fault data information and the state information of the warning command is identified, and the preset warning sound is automatically started, so that the function of assisting in executing the warning command is realized.
The application directly outputs the preset alarm sound by identifying the instructions sent by other systems on the bus, can monitor the abnormal state of other systems, can be used as an alarm unit of the alarm system, and directly executes the instructions sent by other systems.
Specifically, the vehicle backup alarm system mainly acquires interactive data information of other external systems in a bus mode. The source and the use of the data information can be known from the content of the data information by sensing an external system through a bus mode. The external system is relative to the vehicle backup alarm system, and may include a vehicle main system and an instrument system.
For example, in a normal case, the main system of the vehicle machine sends fault information to the bus according to the operating states of software and hardware managed by the main system of the vehicle machine, for example, fault information such as abnormal operation of a certain cooling component under the management of the main system of the vehicle machine, and the instrument system can come from the certain cooling component according to the abnormal operation state, and instruct the screen of the instrument system of the operation desk to display an icon of overheat fault of the certain cooling component, etc.
During the period, the problems of instrument system failure, unsmooth communication between the vehicle main system and the instrument system and the like are not eliminated, and the vehicle backup alarm system can assist in alarming or supplement alarming according to the information of the external system.
For example, although the meter system is used for alarming, the meter system may be abnormal, and a scheme for carrying out backup alarming on the meter system is also needed.
Therefore, the backup alarm system can be triggered according to the command of the vehicle main system for displaying the alarm information and the feedback information of the alarm information which cannot be normally displayed by the instrument system, and the preset alarm sound is output.
In this embodiment, the external system processes the abnormal state of the fault class information including instruction information corresponding to the external system fault state:
and starting a preset alarm according to the command sent by the external system and corresponding to the fault state of the external system.
Specifically, for example, the vehicle main system has self-detection capability, can acquire information fed back by the instrument system from the bus, knows that the instrument system has a fault, or can not normally acquire the feedback information of the instrument system, and can directly change a mode of sending an instruction to the backup alarm system, and the backup alarm system temporarily serves as the instrument system or replaces a part of functions of the instrument system to send alarm sounds. At this time, the backup alarm system corresponds to an alarm unit of the whole alarm system or the instrument system.
For example, the vehicle host system and the meter system may detect each other's communication unblocked through network probe technology.
In this embodiment, the processing of the abnormal state of the fault class information by the external system further includes, correspondingly processing the information of the abnormal alarm function in the fault class information:
according to an alarm command sent by an external system, receiving information of abnormal alarm function;
and starting a preset alarm according to the received information of abnormal alarm function and corresponding alarm command.
Specifically, the meter system receives the warning command from the vehicle main system, but automatically detects that a fault exists when the warning command is executed to perform a warning function. The instrument system sends information of abnormal warning function to the vehicle backup warning system, and the backup warning system replaces the instrument system to execute warning command. The backup alarm system replaces the instrument system, monitors fault information sent by the host system and performs auxiliary backup alarm.
In this embodiment, the processing of the abnormal state of the fault class information by the external system further includes:
the fault class information of the first external system is received and comprises an alarm command sent by the external system;
the receiving of the fault class information of the second external system comprises executing feedback information of the warning command;
judging whether feedback information for executing the warning command is delayed compared with warning command sent by an external system, and judging whether the feedback information exceeds a preset delay threshold;
if the preset delay threshold is exceeded, corresponding to the fault information of the first external system, starting a preset alarm.
Specifically, the external system may be a vehicle main system or an instrument system, and is an external system with respect to the vehicle backup alarm system. The vehicle main system does not simply send out fault information, but also reports the time of warning information as an instrument system. Subsystems like instrumentation may also be present in the vehicle host system. The instrument system sometimes has the functions of screen display, warning and alarming, and can also automatically detect and manage fault states of other systems, and the management and output of warning types are carried out on the summarized fault states. Thus, the first external system can be regarded as a vehicle main system, and the second external system can be regarded as an instrument system. For example, the vehicle-mounted system sends fault information to the bus and includes an alarm command, and if the instrument system receives the alarm command, a preset alarm function is realized according to the alarm command, such as displaying an alarm icon, sending alarm sound, and the like. After the warning function is executed, information for executing a warning command is sent to the bus, for example, a control screen is lightened to display an icon, or other components are driven according to the warning command, and feedback information is left on the bus. The warning backup system can receive warning commands from the bus and also can receive execution information of the corresponding warning commands.
In general, after receiving the data information of the warning command, the backup warning system can receive the information of the warning command executed by the corresponding instrument system soon. It is not excluded that the resource of the meter system is occupied by other processes, and the warning command cannot be immediately executed, but the warning command is executed quickly within a preset time, which is the capability that the meter system should have. Therefore, the backup alarm system can filter the alarm command and the corresponding feedback information, and through delay verification, if the feedback information corresponding to the alarm command is not received for a long time, the alarm command can be timely executed according to the alarm command instead of the instrument system to send out the alarm sound. Meanwhile, the instrument system can also be warned that the suspected fault or abnormality of the vehicle main system cannot be responded quickly.

and the alarm module is used for starting a preset alarm according to the information of the received external system.
It should be noted that, although the system only discloses the information receiving module and the alarm module, the present application is not limited to the above basic functional module, but rather, the present application is intended to mean that one skilled in the art may add one or more functional modules to the above basic functional module to form an infinite number of embodiments or technical solutions, that is, the system is open rather than closed, and the scope of protection of the claims of the present application is not limited to the above disclosed basic functional module because the present embodiment only discloses individual basic functional modules.
